Best Quiet Flush Toilets for Light Sleepers
A quiet toilet is almost always a gravity-flush toilet, because the soft pull of falling water never produces the loud whoosh of a pressure assist model. These picks are ranked on flush mechanism, refill-valve noise, MaP flush-test scores, water use and aggregated owner reviews so a 2am flush does not wake the house, while still clearing the bowl on the first try.
Why Trust Best Flushing Toilets
- Flushing power and MaP flush-test scores
- Water efficiency (GPF and EPA WaterSense)
- Aggregated owner reviews
- Clog resistance and trapway design
- Brand reliability and warranty
Research updated June 2026.
Quick Answer
The quietest flushing toilet is the TOTO Drake II, a gravity model whose Double Cyclone siphon clears a 1,000-gram MaP load with a smooth, low-rumble flush and a quiet refill. For the softest possible operation, the Kohler San Souci one-piece skirted design is the near-silent pick.
If you have ever been jolted awake by a toilet down the hall, you already know that not all flushes are created equal. The single biggest noise variable is the flush mechanism itself. A pressure assisted toilet uses compressed air to blast water through the bowl, which is what makes it the loudest residential fixture you can buy. A gravity toilet, by contrast, relies only on the weight of falling water to siphon the bowl, so it works quietly by design. For a light sleeper, a senior who wakes easily, a nursery next to a bathroom, or an open-plan apartment where the toilet shares a wall with the living space, the choice is clear: a well-engineered gravity toilet with a slow-closing, low-noise refill valve is the answer.
This guide ranks toilets on how quietly they flush and refill, without sacrificing the clearing power you actually need. We lean on the MaP (Maximum Performance) test, an independent benchmark that measures how many grams of solid waste a toilet clears in a single flush, where 600 grams is very good and 1,000 grams is the maximum the test awards. We weigh that against water use in gallons per flush, EPA WaterSense status, the design of the fill valve and flush valve, the trapway, and the pattern of aggregated owner reviews across major retailers, with extra weight on any reviewer who specifically mentions noise. For the wider view across every flush type, see our pillar guide to the best flushing toilets.
How we research and rank. We do not test toilets in a lab and we never claim to. Our rankings compare published manufacturer specifications, third-party MaP flush-test scores, EPA WaterSense certification status and the pattern of aggregated owner reviews across major retailers. For a quiet-flush list we weight flush mechanism and refill-valve noise first, then strong-but-smooth clearing performance, then water efficiency. Where a model carries a known noise quirk, such as a loud aftermarket fill valve or a gurgling trapway, in long-term reviews, we say so rather than calling it a universal winner.
What Makes a Toilet Quiet?
A toilet is quiet when it uses a gravity flush rather than pressure assist, and pairs it with a slow-closing or float-cup fill valve that refills the tank gently instead of with a hiss. Smooth siphonic bowl designs like TOTO's Double Cyclone and Tornado Flush move water without splashing or gurgling, and a one-piece skirted body dampens vibration further. Pressure assisted toilets are the loudest and should be avoided by light sleepers.
Toilet noise comes from three separate events, and a quiet toilet manages all three. The first is the flush itself, where a pressure assist toilet releases compressed air in a loud surge while a gravity toilet simply lets water fall and siphon, producing a soft rush instead of a bang. The second is the refill, when the fill valve reopens to recharge the tank; an old ballcock valve hisses loudly while a modern slow-closing float-cup valve fills with a gentle gurgle. The third is bowl behavior, where a well-shaped siphonic trapway draws the bowl down smoothly without the air-gulping glug that cheap toilets make. The picks below were chosen because they handle all three quietly, and where a fill valve can be quieted further with an inexpensive upgrade, we note it.

Which Toilet Is the Quietest to Flush?
The quietest toilets to flush are gravity-fed one-piece models such as the Kohler San Souci and TOTO UltraMax II, because the seamless skirted body dampens vibration and the siphonic bowl draws water down without gurgling. Their slow-closing fill valves refill the tank with a soft gurgle rather than a hiss, so the whole flush-and-refill cycle stays gentle enough not to wake a light sleeper in the next room.
One-piece toilets tend to be the quietest because the tank and bowl are fused into a single mass of vitreous china, which absorbs and deadens the small vibrations that a two-piece toilet can transmit through the bolts joining its separate tank. Add a skirted, fully enclosed base and there are fewer hard edges to ring or rattle. The flush mechanism matters even more than the body, though, which is why TOTO and Kohler lead this list: their gravity siphons are tuned to pull the bowl down in a smooth, continuous draw rather than a series of glugs, and their factory fill valves close slowly to avoid the water-hammer thunk and prolonged hiss that make a cheap toilet sound loud at 2am.
Are Pressure Assisted Toilets Too Loud for a Bedroom?
Yes, pressure assisted toilets are too loud for a bedroom or any space where quiet matters. The compressed-air surge that gives them their strong flush also produces a distinct loud whoosh that is the most common complaint in owner reviews. Light sleepers, nurseries and ensuite bathrooms that share a wall with a bedroom should choose a gravity toilet, which clears just as effectively at the same water use but far more quietly.
Pressure assist has a real place: it is the most clog-resistant flush you can install, and for a hard-use main bathroom or basement that power is worth the noise. But in a bedroom-adjacent location it is the wrong tool. The good news is that you give up almost nothing on clearing power by choosing gravity, because the top gravity models on this list, like the TOTO Drake II and UltraMax II, reach the same perfect 1,000-gram MaP score as a pressure toilet while flushing quietly. If you want the loud-but-powerful comparison, see our roundup of pressure assisted toilets, but for a quiet home, stay with gravity.
Does a Quiet Toilet Still Flush Well?
Yes, a quiet gravity toilet can flush extremely well. The TOTO Drake II and UltraMax II both reach a perfect 1,000-gram MaP score, the maximum the test awards, while flushing quietly thanks to TOTO's Double Cyclone siphon. Quiet operation and strong clearing are not opposites: a well-engineered siphonic bowl moves water efficiently and smoothly, so it clears a heavy load on the first try without the noise of a pressure flush.
The myth that a quiet toilet must be weak comes from old low-flow toilets of the 1990s, which were both quiet and genuinely bad at clearing. Modern siphonic engineering changed that. A toilet like the Drake II uses two water jets and a precisely shaped trapway to start the siphon quickly and pull the bowl down in one smooth, powerful action that happens to be quiet. The MaP scores back it up: a 1,000-gram rating means the bowl clears a load far larger than any real-world use, quietly. So you do not have to choose. For families that combine quiet needs with heavy use, our guide to the best toilets for large families weighs both clearing power and reliability.

The 8 best quiet flush toilets
Each pick below is ranked on quiet flush and refill operation first, then smooth-but-strong clearing performance, then water efficiency and value, cross-checked against aggregated owner reviews that mention noise.
1
Best overall
TOTO Drake II
4.7
Best for: quiet plus power
The Drake II is the toilet to beat for anyone who wants a soft, low-rumble flush without giving up clearing power. Its Double Cyclone gravity siphon uses two water jets to start the siphon fast and pull the bowl down in a smooth, continuous draw, earning a perfect 1,000-gram MaP score at an efficient 1.28 gallons while staying noticeably quieter than a pressure toilet.
Flush TypeDouble Cyclone gravity siphon
GPF1.28
MaP Score1,000 g
Bowl Height16.125 in (comfort)
Warranty1-year limited
Best For
- Smooth, low-rumble gravity flush with no pressure whoosh
- Perfect 1,000-gram MaP clearing at an efficient 1.28 gallons
- Quiet factory fill valve and EPA WaterSense certification
Not Ideal For
- Buyers who want a fully seamless one-piece body
- Anyone needing the absolute lowest 0.8-gallon water use
The Double Cyclone system is the quiet workhorse here. By feeding the bowl through two angled jets instead of a single rim hole, it builds the siphon smoothly and avoids the gulping glug of cheaper trapways, so the flush is a soft rush rather than a clatter. The CeFiONtect glaze keeps the bowl clean, which also means fewer noisy repeat flushes.
Owner reviews consistently call it powerful and quiet in the same breath, a rare combination, and specifically praise how little it disturbs a sleeping household. The two-piece body is the only knock for those chasing the very quietest option, since a one-piece deadens vibration slightly more, but the flush mechanism itself is best in class. It is WaterSense certified, so the quiet flush is also a frugal one.
Expert Take
Check price on Amazon
If you want one toilet that flushes quietly yet clears like a powerhouse, this is it. The Drake II proves the two goals are not in conflict. For a light sleeper who also fights the occasional heavy load, nothing else on this list matches its blend of a soft gravity flush and a perfect MaP score, and the quiet refill seals the case.
Bottom Line: The best mix of a quiet gravity flush and perfect clearing power, ideal for a light sleeper who still wants a strong toilet.
2
Quietest overall
Kohler San Souci
4.6
Best for: near-silent flush
The San Souci is the pick when quiet is the single priority. Its low-profile, fully skirted one-piece body fuses tank and bowl into one mass of vitreous china that absorbs vibration, and Kohler's AquaPiston canister flush opens a 3-inch valve for a fast, smooth draw that is among the softest-sounding gravity flushes you can buy.
Flush TypeAquaPiston canister gravity
GPF1.28
MaP Score800 g
Bowl Height15 in (standard)
Warranty1-year limited
Best For
- Seamless skirted one-piece body that deadens vibration
- Smooth AquaPiston canister flush with a soft sound
- Low-profile design that suits nurseries and tight ensuites
Not Ideal For
- Heavy loads that demand a full 1,000-gram MaP score
- Taller users who prefer a comfort-height seat
The AquaPiston canister sits at the center of the tank and lifts straight up to release water through a 360-degree opening, which fills the bowl evenly and quietly instead of through a single side flapper. Fewer moving parts also means fewer rattles and a more reliable seal over time, so the toilet stays quiet for years rather than developing a noisy run.
Owner reviews praise the looks and the genuinely soft flush, with the low 15-inch height and the 800-gram MaP score being the trade-offs versus the taller, harder-clearing picks. For a powder room, a nursery-adjacent bath or any space where a near-silent flush matters more than maximum clearing, it is the standout, and the skirted base also wipes clean in seconds.
Expert Take
Check price on Amazon
When the goal is the quietest possible toilet and loads are typical rather than extreme, the San Souci wins. The fused one-piece body and canister flush make it one of the softest-sounding fixtures on the market. Just match it to a normal-use bathroom rather than a hard-hammered family main bath, where a 1,000-gram pick serves better.
Bottom Line: The softest-sounding pick here, with a seamless one-piece body ideal for nurseries and quiet ensuites.
3
Best one-piece
TOTO UltraMax II
4.7
Best for: quiet and strong
The UltraMax II takes the Drake II's powerful, quiet flush and wraps it in a sleek one-piece body, giving you the best of both worlds. The same Double Cyclone gravity siphon earns a perfect 1,000-gram MaP score at 1.28 gallons, while the fused tank-and-bowl construction deadens vibration for an even softer overall sound than the two-piece version.
Flush TypeDouble Cyclone gravity siphon
GPF1.28
MaP Score1,000 g
Bowl Height16.5 in (comfort)
Warranty1-year limited
Best For
- One-piece body that deadens vibration for a softer flush
- Perfect 1,000-gram MaP clearing at an efficient 1.28 gallons
- Comfort height seat and easy-clean seamless surfaces
Not Ideal For
- Buyers on a tight budget, since one-piece costs more
- Anyone who needs a 0.8-gallon ultra-low-flow flush
This is the toilet for the buyer who refuses to compromise: it flushes as quietly and clears as powerfully as anything on the list, in a body that is both attractive and easy to keep clean. The Double Cyclone jets start the siphon smoothly, and the one-piece china carries less vibration than a bolted two-piece tank, so the whole flush-and-refill cycle is gentle.
Owner reviews echo the Drake II on power and quiet, adding praise for the seamless styling and the comfort height seat. The only real trade-off versus the Drake II is price, since one-piece construction costs more to manufacture. For a primary bathroom where a quiet, strong, good-looking toilet is worth the spend, it is the top one-piece pick and overlaps with our best toilets of 2026.
Expert Take
Check price on Amazon
If your budget reaches the one-piece tier, the UltraMax II is the easy call for a quiet primary bathroom. You get the Drake II's perfect MaP flush, an even softer sound from the fused body, and styling that suits a nicer bath. It is the no-compromise quiet pick when looks and clearing both matter.
Bottom Line: A perfect-MaP quiet flush in a seamless one-piece body, the no-compromise pick for a quiet primary bathroom.
4
Best compact
Kohler Santa Rosa
4.6
Best for: small quiet baths
The Santa Rosa packs a quiet, strong flush into a space-saving compact-elongated one-piece body, making it the pick for a small bathroom that still needs gentle operation. Kohler's AquaPiston canister flush draws the bowl down smoothly for a perfect 1,000-gram MaP score at 1.28 gallons, while the fused body keeps vibration and noise low.
Flush TypeAquaPiston canister gravity
GPF1.28
MaP Score1,000 g
Bowl Height16.5 in (comfort)
Warranty1-year limited
Best For
- Compact-elongated body that fits tight bathrooms
- Quiet AquaPiston flush with a perfect 1,000-gram MaP score
- One-piece construction that dampens flush noise
Not Ideal For
- Buyers who want the very softest 800-gram-class flush
- Anyone needing the deepest comfort of a full elongated bowl
The Santa Rosa is one of the few toilets that gives you elongated-bowl comfort in a footprint close to a round bowl, which is why it is a favorite for small bathrooms and apartments. The AquaPiston canister releases water evenly around the rim, starting the siphon quickly and quietly, and the comfort height seat suits most adults.
Owner reviews praise the space savings, the strong flush and the quiet, reliable canister mechanism, with the main note being that the compact bowl is slightly shorter front-to-back than a full elongated one. For a quiet powder room or a tight ensuite that still needs full clearing power, it is the standout compact pick, and it appears in our roundup of the best toilets for home.
Expert Take
Check price on Amazon
When space is tight but you still want a quiet, full-strength flush, the Santa Rosa is the smart compromise. It delivers a perfect MaP score and a soft canister flush in a footprint that fits where a full elongated one-piece will not. For small quiet bathrooms, that combination is hard to beat.
Bottom Line: A quiet, perfect-MaP flush in a compact one-piece body, ideal for small bathrooms that still need full clearing power.
5
Best dual flush
TOTO Aquia IV
4.5
Best for: water savings
The Aquia IV is the quiet pick for households that also want to save water, pairing TOTO's smooth Dual Max flushing with a dual-flush button that selects 0.8 gallons for liquid waste or 1.28 gallons for solids. The light 0.8-gallon flush is especially quiet, moving little water, which makes a late-night liquid flush almost unnoticeable.
Flush TypeDual Max gravity, dual flush
GPF0.8 / 1.28
MaP Score1,000 g
Bowl Height16.5 in (comfort)
Warranty1-year limited
Best For
- Light 0.8-gallon flush that is very quiet and water-thrifty
- Dual-flush button lets you match water and noise to the load
- Skirted body that wipes clean and looks modern
Not Ideal For
- Buyers who dislike top-mounted dual-flush buttons
- Anyone who prefers a simpler single-flush handle
Dual flush gives a light sleeper a useful trick: for the most common nighttime visits you press the half-flush, which uses just 0.8 gallons and is among the quietest flushes possible because so little water moves. The full 1.28-gallon flush handles solids with the smooth Dual Max siphon at a perfect 1,000-gram MaP score, and the skirted body looks clean and modern.
Owner reviews highlight the water savings and the quiet half-flush, with the only real trade-off being the need to occasionally use the full flush for heavier loads, since the full flush itself already matches the 1,000-gram leaders on clearing power. For an eco-minded home that values both quiet and a low water bill, it is the standout, and it features in our best toilets of 2026 roundup.
Expert Take
Check price on Amazon
The Aquia IV is the pick when you want quiet and water savings together. The 0.8-gallon half-flush is the quietest flush in this guide for routine use, which is exactly what a light sleeper wants for a 3am visit. Just rely on the full flush for solids, and the perfect 1,000-gram rating means it is never an issue.
Bottom Line: The quietest routine flush here thanks to a 0.8-gallon half-flush, ideal for an eco-minded household.

Best value
Woodbridge T-0019
4.5
Best for: quiet on a budget
Woodbridge built its reputation on TOTO-style quiet one-piece toilets at a fraction of the price, and the T-0019 is its strong-flushing value pick. The dual siphon-jet gravity flush earns a perfect 1,000-gram MaP score at 1.28 gallons, and the fully skirted one-piece body keeps both vibration and cleaning effort low.
Flush TypeDual siphon-jet gravity
GPF1.28
MaP Score1,000 g
Bowl Height16.5 in (comfort)
Warranty5-year limited
Best For
- Quiet skirted one-piece body at a value price
- Perfect 1,000-gram MaP flush from a dual siphon jet
- Soft-close seat and easy-clean glazed surface included
Not Ideal For
- Buyers who want the long-term parts depth of TOTO or Kohler
- Anyone who insists on a name-brand fill valve from the factory
The T-0019 delivers the quiet one-piece experience for far less than the premium brands. The dual siphon jets start the flush smoothly and clear the bowl forcefully, and the included soft-close seat means no slamming lid to wake the house, a noise source people often forget. The skirted base wipes clean in seconds.
Owner reviews are strong on the quiet, powerful flush and the value, with the main cautions being that the long-term parts network is smaller than TOTO's or Kohler's, and a small number of owners eventually swap the fill valve for a name-brand unit to keep the refill quiet. For a quiet upgrade on a budget, it punches well above its price and overlaps with our best toilets for home picks.
Expert Take
Check price on Amazon
The T-0019 is the value answer for a quiet bathroom. You get a skirted one-piece body, a perfect MaP flush and a soft-close seat for well under the premium brands. Keep a name-brand fill valve in mind as a cheap future upgrade if the original ever gets noisy, and it will stay quiet for years.
Bottom Line: A quiet skirted one-piece with a perfect MaP flush at a value price, the best budget pick for a quiet bathroom.
7
Best two-piece
Kohler Cimarron
4.5
Best for: classic quiet
The Cimarron is Kohler's most popular two-piece toilet, and it pairs a quiet, strong AquaPiston canister flush with the brand's enormous parts and service network. It earns a perfect 1,000-gram MaP score at 1.28 gallons, and the canister mechanism gives it one of the smoothest, quietest flushes in the affordable two-piece class.
Flush TypeAquaPiston canister gravity
GPF1.28
MaP Score1,000 g
Bowl Height16.5 in (comfort)
Warranty1-year limited
Best For
- Quiet, reliable AquaPiston canister flush
- Perfect 1,000-gram MaP score at 1.28 gallons
- Kohler's deep parts network keeps it quiet long-term
Not Ideal For
- Buyers who want a fully seamless one-piece body
- Anyone seeking the absolute softest possible flush sound
The AquaPiston canister is the quiet heart of the Cimarron. By releasing water in a 360-degree pattern through a center-mounted valve, it starts the siphon smoothly and avoids the flapper-driven slosh of older designs, while having fewer parts that can wear into a noisy run. Kohler stocks every component, so a quiet flush stays quiet for the life of the toilet.
Owner reviews praise the strong, smooth flush and the easy availability of parts, with the two-piece body being the only reason a noise purist might step up to a one-piece. For a reliable, widely supported toilet that flushes quietly and clears completely, the Cimarron is the classic value choice and appears in our best toilets for home guide.
Expert Take
Check price on Amazon
The Cimarron is the safe, sensible quiet two-piece. The canister flush is smooth and dependable, and Kohler's parts depth means you can keep it quiet for decades with cheap, easy-to-find replacements. It is not the very softest here, but it is the easiest to live with long-term.
Bottom Line: A quiet, perfect-MaP two-piece backed by Kohler's deep parts network, the dependable classic pick.

Best modern look
Swiss Madison St. Tropez
4.4
Best for: contemporary baths
The St. Tropez brings a sleek, European-styled one-piece body to the quiet-flush category, with a dual-flush button that selects 0.8 or 1.1 gallons. The very low water volume keeps both flushes quiet, and the fully skirted, low-profile design suits a modern bathroom where the toilet should be seen but not heard.
Flush TypeDual flush gravity, siphonic
GPF0.8 / 1.1
MaP Score800 g
Bowl Height16.5 in (comfort)
Warranty1-year limited
Best For
- Sleek skirted one-piece body for modern bathrooms
- Low 0.8 to 1.1-gallon flushes that stay quiet
- Soft-close seat and dual-flush water savings included
Not Ideal For
- Heavy loads that want a 1,000-gram MaP score
- Buyers who prioritize a deep brand parts network
The St. Tropez is the design-forward quiet pick. Its low water volume means the flush moves gently, and the seamless skirted body both looks clean and damps vibration. The included soft-close seat eliminates lid-slam noise, and the compact, contemporary shape fits small modern baths where styling matters as much as function.
Owner reviews praise the looks, the quiet low-volume flush and the value, with the cautions being the 800-gram MaP score, which suits typical rather than extreme loads, and a smaller parts network than the legacy brands. For a contemporary bathroom that wants a quiet, water-thrifty toilet with a designer feel, it is the standout, and it overlaps with our best toilets of 2026 roundup.
Expert Take
Check price on Amazon
The St. Tropez is the pick when you want a quiet flush in a toilet that actually looks the part of a modern bathroom. The low water volume keeps it gentle, and the soft-close seat removes the lid slam most people forget about. Match it to normal use, not a hard-hammered family bath, and it delivers quiet style.
Bottom Line: A quiet, low-volume flush in a sleek skirted one-piece, the design pick for a modern bathroom.
Expert Take
Across all eight, the lesson is that quiet starts with the flush mechanism, not marketing. Every pick here is gravity-fed, because a pressure assist toilet simply cannot be quiet. Within gravity, the differences are small and come down to body type and fill valve: a one-piece skirted body like the San Souci or UltraMax II deadens vibration best, a dual-flush model like the Aquia IV offers the quietest routine flush at 0.8 gallons, and a soft-close seat on any of them removes the lid-slam most people overlook. Choose a 1,000-gram model if loads run heavy, and replace any noisy factory fill valve with a slow-closing one for a few dollars.
Buying advice
How to choose a quiet flush toilet
A few details on the spec sheet decide how quiet a toilet really is. Focus on these four factors and you will pick a toilet that clears the bowl without waking the house.
Choose gravity flush, not pressure assist
This is the single most important rule for a quiet toilet, and it overrides everything else. A pressure assisted toilet releases compressed air to drive the flush, which produces a loud whoosh that is the leading complaint in pressure-toilet reviews and is plainly too loud for a bedroom-adjacent bathroom. A gravity toilet uses only the weight of falling water to start a siphon, so it works quietly by design. The good news is you sacrifice nothing on clearing power, because the best gravity models reach the same perfect 1,000-gram MaP score as a pressure toilet. If a salesperson or listing pushes pressure assist for a quiet bedroom bath, that is the wrong recommendation. For the loud-but-powerful alternative and when it makes sense, see our pressure assisted toilets guide.
Quiet tip. The flapper or canister inside the tank also affects noise. A canister flush, like Kohler's AquaPiston, opens straight up through a center valve and tends to sound smoother and quieter than a side-hinged flapper, while also lasting longer before it develops a noisy phantom run. If two toilets are otherwise equal, the canister design is the quieter long-term choice.
Pick a quiet, slow-closing fill valve
After the flush ends, the fill valve reopens to recharge the tank, and this refill is often the loudest and longest part of the whole cycle. Old ballcock valves hiss loudly for thirty seconds or more, while a modern float-cup or slow-closing valve fills with a gentle, brief gurgle. TOTO and Kohler ship quiet factory valves, which is part of why they lead this list. On a budget toilet, or on any older toilet that has gotten noisy, you can drop in a quiet slow-closing fill valve for a few dollars in about fifteen minutes, and it is the single most effective quieting upgrade you can make. If a toilet you otherwise love has a noisy fill complaint in reviews, treat that valve swap as a cheap, easy fix rather than a dealbreaker.
Favor a one-piece, skirted body
The toilet body itself transmits or absorbs sound. A two-piece toilet joins a separate tank to the bowl with bolts and a gasket, which can transmit small vibrations and occasionally rattle, while a one-piece toilet fuses tank and bowl into a single mass of vitreous china that absorbs those vibrations and sounds noticeably softer. A skirted, fully enclosed base removes hard edges that can ring and, as a bonus, wipes clean in seconds. If quiet is your top priority, a one-piece skirted model like the Kohler San Souci or TOTO UltraMax II is the body style to choose. A two-piece like the Drake II or Cimarron is still quiet thanks to its flush mechanism, but the one-piece edges it out on pure sound.
Seat tip. Do not overlook the toilet seat. A standard hinged seat slams down with a sharp crack that can be louder than the flush itself, especially at night. A soft-close seat lowers slowly and silently, and most quiet-focused toilets, including the Woodbridge T-0019 and Swiss Madison St. Tropez, include one. If your chosen toilet does not, add a soft-close seat for a few dollars; it is the cheapest quiet upgrade in the bathroom.
Match clearing power to your real use
Quiet does not mean weak, but you should still match the MaP score to your household. A 1,000-gram model like the Drake II, UltraMax II, Santa Rosa, Woodbridge T-0019, Cimarron or the dual-flush Aquia IV clears any real-world load on the first quiet flush, which matters in a busy family bath because a second flush is twice the noise. An 800-gram model like the San Souci or St. Tropez is plenty for a typical powder room, ensuite or low-traffic bathroom, and the lower-volume dual-flush options are actually the quietest for routine use. Pick the higher MaP score for a hard-use main bathroom and the lighter, lower-water options for a quiet secondary bath. For homes that combine quiet needs with heavy daily use, our best toilets for large families guide weighs clearing power and reliability together.
What Is a Good MaP Score for a Quiet Toilet?
A good MaP score is 800 grams or higher, and 1,000 grams is the maximum the test awards. For a quiet toilet, a 1,000-gram gravity model like the TOTO Drake II clears any load on the first flush, which keeps things quiet by avoiding a noisy second flush. An 800-gram model is plenty for a normal-use bathroom, and lower-volume dual-flush picks are often the quietest for routine nighttime use.
Expert Take
If you remember one thing, make it this: a quiet toilet is a gravity toilet with a slow-closing fill valve and, ideally, a one-piece skirted body and a soft-close seat. Get those right and the toilet will be quiet regardless of brand. The TOTO Drake II and UltraMax II prove you never have to trade clearing power for quiet, while a dual-flush model like the Aquia IV gives a light sleeper the gentlest possible 0.8-gallon flush for routine late-night visits.
Our Verdict
For most light sleepers the TOTO Drake II is the one to buy: a smooth Double Cyclone gravity flush, a perfect 1,000-gram MaP score, a quiet refill and EPA WaterSense efficiency at 1.28 gallons. Step up to the TOTO UltraMax II for an even softer one-piece body, choose the Kohler San Souci for the near-silent pick, the TOTO Aquia IV for the quietest 0.8-gallon routine flush, or the Woodbridge T-0019 for quiet on a budget. Avoid pressure assist, add a soft-close seat, then check the current price on Amazon.
FAQ
Common questions about quiet flush toilets
? What is the quietest type of toilet?
A gravity-fed toilet is the quietest type, because it uses only the weight of falling water to start a siphon rather than the loud compressed-air surge of a pressure assisted toilet. The very quietest are one-piece skirted gravity models with a slow-closing fill valve, such as the Kohler San Souci or TOTO UltraMax II, where the fused body deadens vibration and the refill is a soft gurgle instead of a hiss.
? Why is my toilet so loud when it flushes?
The most common causes are a pressure assisted flush mechanism, a noisy old fill valve that hisses on refill, or a worn flapper that lets the bowl gurgle. A loud, prolonged refill is usually the fill valve, which you can replace with a quiet slow-closing valve in about fifteen minutes. If the loud noise is the flush itself, you likely have a pressure assist toilet, which is loud by design.
? Are one-piece toilets quieter than two-piece?
Generally yes, slightly. A one-piece toilet fuses the tank and bowl into a single mass of vitreous china that absorbs vibration, while a two-piece joins a separate tank with bolts that can transmit small sounds or rattle. The flush mechanism matters more than the body, though, so a well-engineered two-piece like the TOTO Drake II is still very quiet.
? Can a quiet toilet still flush powerfully?
Yes. The TOTO Drake II and UltraMax II both reach a perfect 1,000-gram MaP score, the maximum the test awards, while flushing quietly thanks to a smooth siphonic design. Modern gravity toilets prove that quiet operation and strong clearing are not opposites, so you do not have to choose between a soft flush and a clean bowl.
? How do I make my existing toilet quieter?
Replace the fill valve with a quiet slow-closing or float-cup valve, which is the most effective and cheapest fix and takes about fifteen minutes. Add a soft-close seat to eliminate lid slam, partly close the supply shutoff to slow the refill if it hammers, and replace a worn flapper to stop phantom gurgling. Together these often quiet an existing toilet without replacing it.
? Is a pressure assisted toilet ever a good choice for a quiet home?
Only for a bathroom far from any bedroom or living space, such as a basement, workshop or hard-use main bath where its strong clog resistance is worth the noise. For an ensuite, a nursery-adjacent bath or any light-sleeper situation, a pressure assist toilet is too loud, and a gravity toilet clears just as well far more quietly.
? What fill valve is the quietest?
A modern float-cup or slow-closing fill valve is the quietest, because it shuts off gradually to avoid the water-hammer thunk and prolonged hiss of an old ballcock valve. TOTO and Kohler ship quiet valves from the factory. On any noisy toilet, a quiet aftermarket fill valve is an inexpensive, effective upgrade you can install yourself.
? Does dual flush make a toilet quieter?
The light setting does. A dual-flush toilet like the TOTO Aquia IV lets you use a 0.8-gallon flush for liquid waste, and because so little water moves, that half-flush is among the quietest flushes possible, ideal for a routine late-night visit. The full flush for solids is a normal-volume gravity flush, still quiet but louder than the half-flush.
? Why does my toilet make a loud noise after flushing?
That noise after the flush is the tank refilling through the fill valve. A loud hiss or a vibrating water-hammer sound usually means an old or failing fill valve, or a supply shutoff opened so far that water rushes in fast. Replacing the valve with a quiet slow-closing model and slightly throttling the shutoff almost always solves it.
? Are TOTO toilets quiet?
Yes, TOTO toilets are among the quietest available. The Double Cyclone and Tornado Flush siphonic systems pull the bowl down smoothly without gurgling, and TOTO ships quiet factory fill valves. Models like the Drake II and UltraMax II combine that quiet operation with a perfect 1,000-gram MaP score, making them favorites for light sleepers.
? Are Kohler toilets quiet?
Yes. Kohler's AquaPiston canister flush, used in the Cimarron, Santa Rosa and San Souci, releases water through a center valve in a smooth 360-degree pattern that sounds quieter than a side-hinged flapper and lasts longer before developing a noisy run. Paired with Kohler's quiet factory fill valves, these models are strong quiet-flush choices.
? Will a quiet toilet wake a sleeping baby in the next room?
A good gravity toilet with a quiet fill valve and a soft-close seat is unlikely to wake a sleeping baby through a wall, especially using a dual-flush half-flush. The biggest avoidable noise is a slamming seat, so a soft-close seat is essential near a nursery. Avoid pressure assist entirely, since its loud whoosh can carry through walls.
? Does water pressure affect toilet noise?
Yes. Very high home water pressure makes the fill valve refill faster and louder and can cause water hammer, the banging in pipes after a flush. Partly closing the supply shutoff valve slows the refill and quiets it, and a pressure-reducing valve helps if your whole-home pressure is high. Gravity toilets are far less pressure-sensitive than pressure assist models.
? What is a canister flush and is it quieter?
A canister flush uses a center-mounted valve that lifts straight up to release water in a 360-degree pattern, instead of a side-hinged flapper. It tends to sound smoother and quieter, fills the bowl more evenly, and lasts longer before it wears into a leaky, gurgling run. Kohler's AquaPiston is a common canister design found in quiet models.
? Are skirted toilets quieter?
Skirted toilets can be marginally quieter because the enclosed base removes hard edges that might ring, and most skirted models are one-piece designs that already deaden vibration. The bigger benefit of a skirt is easy cleaning, but in a quiet-focused toilet the seamless body and skirt together help keep operation soft.
? Do EPA WaterSense toilets flush quietly?
Generally yes, because most WaterSense toilets are efficient gravity models that move 1.28 gallons or less, and lower water volume tends to mean a softer flush. WaterSense certification confirms both strong flushing performance and low water use, so a certified gravity toilet like the TOTO Drake II is quiet and frugal at the same time.
? How much does it cost to make a toilet quieter?
Very little. A quiet slow-closing fill valve and a soft-close seat are each inexpensive parts you can install yourself in well under an hour, and together they address the two loudest noises, the refill hiss and the lid slam. Replacing the whole toilet is only worth it if the flush mechanism itself, such as a pressure assist unit, is the problem.
? Is a half-flush enough for solid waste?
No, the 0.8-gallon half-flush on a dual-flush toilet is designed for liquid waste and paper only, and you should use the full flush for solids. For light sleepers this still helps, since most routine nighttime visits only need the quiet half-flush, and the full flush is available whenever a heavier load calls for it.
? Which brands make the quietest toilets?
TOTO and Kohler lead for quiet operation, thanks to smooth siphonic and canister flush designs and quiet factory fill valves. Woodbridge offers quiet TOTO-style one-pieces at a lower price, and Swiss Madison makes quiet, low-volume modern designs. All four are gravity-based, which is the foundation of a quiet flush.
? Do round or elongated bowls flush more quietly?
Bowl shape has little effect on flush noise; the mechanism and fill valve matter far more. A round bowl saves space and an elongated bowl is more comfortable, but both flush at the same volume on a given model. Choose the shape that fits your bathroom and let the flush type and fill valve determine how quiet it is.
