Best Round Toilets for Small Bathrooms

A round-front bowl is the single most reliable way to shrink a toilet's footprint, because it projects roughly four inches less from the wall than an elongated bowl. In a small bathroom those inches decide whether a door clears the seat and whether the room feels open or cramped. We ranked the best round toilets by published bowl projection, independent MaP flush-test scores, EPA WaterSense certification, gallons per flush and the patterns across thousands of aggregated owner reviews, then balanced footprint against flush power so you never have to apologize for a second flush.

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

Quick Answer

The TOTO Drake in its round-front version is the best round toilet for small bathrooms. It pairs a short projection with a top-tier 1,000-gram MaP flush at an efficient 1.28 gallons, so you reclaim floor depth without losing flush power. For the best value choose the round American Standard Cadet 3, and for the cleanest compact one-piece pick the round Kohler Santa Rosa.

A round toilet is defined by the shape of its bowl, and that shape solves the one problem every small bathroom shares: not enough floor depth. A round-front bowl is shorter and more circular than an elongated bowl, projecting roughly 25 to 27 inches from the finished wall versus 29 to 31 inches for an elongated model. That difference of three to five inches is exactly what decides whether a door clears the seat, whether your knees press against a facing vanity, and whether a tiny powder room is comfortable or claustrophobic. Manufacturers rarely advertise a model as the best choice for a small bathroom, so the work falls to you to read the spec sheet, compare projections and find the short round bodies that still flush like full-size toilets.

We do not install or test these toilets ourselves. Instead we compare published manufacturer dimensions, independent MaP (Maximum Performance) flush-test scores, EPA WaterSense certification and the patterns across thousands of verified owner reviews. For a small-bathroom pick the priorities shift from a standard roundup. Beyond does it clear the bowl in one flush and does it stay clean, we asked four extra questions for every toilet here: how short is the bowl projection, does the body stay narrow enough to leave the code-required side clearance, does it offer a 10-inch rough-in option for older homes, and does the small round body still post a MaP score strong enough to avoid a second flush. Every model below pairs a genuinely tight footprint with a flush that holds up under daily use. For the full performance-first ranking across every bathroom size, start with our guide to the best flushing toilets.

What Is the Best Round Toilet for a Small Bathroom?

The round-front TOTO Drake is the best round toilet for most small bathrooms because its short bowl projects roughly 26 to 27 inches from the wall while posting a top-tier 1,000-gram MaP flush score at an efficient 1.28 gallons. For the best value, the round American Standard Cadet 3 matches that 1,000-gram flush in an even cheaper body, and the round Kohler Santa Rosa is the cleanest compact one-piece because it has no tank-to-bowl seam to scrub.

How We Research and Rank Round Toilets

Every toilet here had to combine a genuinely short round footprint with a flush that holds up under daily use. We favored bowls that project around 27 inches or less from the wall, narrow bodies that leave room for the code-required 15-inch side clearance, and a MaP score high enough to clear the bowl in one flush. Most of our picks rate 800 to 1,000 grams, where 350 grams is the residential pass threshold and 600 grams or higher is considered strong. We gave weight to EPA WaterSense certification and a 1.28-gallons-per-flush rating or better, since small bathrooms are often powder rooms, secondary baths and rentals where efficiency adds up across the year. We also noted which models offer a 10-inch rough-in version, because small bathrooms in older homes frequently have a shorter rough-in than the standard 12 inches. We weighted verifiable specs and aggregated owner feedback over marketing language, and we do not take payment for placement. The table below summarizes how the picks compare on the numbers that decide a small-bathroom install.

The 9 Best Round Toilets for Small Bathrooms, Reviewed

1
Best Overall

TOTO Drake (Round)

4.7 Small bathrooms

The round-front Drake is the round toilet we recommend to most small-bathroom shoppers because it pairs a short bowl projection with TOTO's powerful G-Max gravity flush, so you reclaim floor depth without dropping to a weak budget model.

Flush TypeSingle, G-Max gravity
GPF1.28
MaP Score1000 grams

Best For
  • Small bathrooms that still see daily use
  • A top-tier flush in a short body
  • Easy access to TOTO parts and service
Not Ideal For
  • Shoppers who want a hidden, skirted trapway
  • Anyone who needs the seat in the box

The round front shaves several inches of projection against an elongated bowl, freeing the depth that decides whether a tiny bath is usable. Despite the compact body, the wide 3-inch flush valve and G-Max siphon jet move a strong, full rinse at an efficient 1.28 gallons, and the model carries EPA WaterSense certification.

Owners consistently rate the Drake among the most reliable single-flush toilets they have owned, with a very low clog rate and a forceful, dependable flush. The styling is plain and the trapway is exposed, so it is a function-first pick rather than a showpiece, and the seat sells separately.

Expert Take

When a small bathroom still has to handle real daily traffic, the round Drake is the safest choice on this list. It delivers a 1,000-gram MaP flush, the same as full-size power toilets, in a short round body, and TOTO's parts availability means it is easy to keep running for years.

Bottom Line: The round toilet that fits a small bathroom without trading away the strong, low-clog flush of a full-size model.

Not Ideal For
  • Shoppers who want a hidden trapway
  • A design-forward look

You are not giving up flush strength to save space or money here. The EverClean surface resists stains and odor-causing bacteria, keeping a small room feeling fresher between cleanings, and a 10-inch rough-in version is available for older walls.

At an efficient 1.28 gallons it keeps water use low, and its strong, dependable owner track record makes it an easy recommendation for a rental, a basement bath or a simple upgrade. The styling is plain and the trapway exposed, but the value against that 1,000-gram flush is hard to beat.

Expert Take

This is the value benchmark the rest of the list is measured against. If a small bathroom needs a strong, low-clog flush and every dollar counts, the round Cadet 3 delivers full-size flush power in a space-saving body, with a 10-inch rough-in option that solves awkward older bathrooms.

Bottom Line: The best value round toilet, pairing a 1,000-gram MaP flush with a short, comfortable-height bowl.

Best One-Piece

Kohler Santa Rosa (Round)

The Santa Rosa is the compact one-piece to beat for a small bathroom. Its seamless body has no tank-to-bowl joint to scrub, which matters far more when you are cleaning at close quarters in a tight room.

Flush TypeSingle, Class Five
GPF1.28
MaP Score800 grams
Bowl HeightComfort (16.5 in)

Best For
  • A modern, seamless small bathroom
  • Owners who hate scrubbing seams
  • A short, low integrated-tank silhouette
Not Ideal For
  • Solo DIY installs (it is heavy)
  • The tightest budgets

The compact bowl sits on a notably short footprint, and the low integrated tank keeps the silhouette down, which reads as more open in a small bathroom. Kohler's Class Five flushing system moves a strong, wide rinse that owners rate highly for single-flush reliability.

Reviewers give it consistently positive notes on how little upkeep the clean lines demand and on the dependable flush. The one-piece body is heavier to lift and costs more than a comparable two-piece, so plan the install with a second pair of hands.

Expert Take

For a tidy, modern small bathroom where you want clean lines and minimal cleaning, this is the standout. The seamless body is worth the extra lift on installation day, and the Class Five flush holds up under regular use without the second-flush problem some water-savers have.

Check price on Amazon
Bottom Line: The easiest round toilet to keep clean, with a strong flush in a genuinely short one-piece body.
TOTO Entrada round toilet

Shortest Projection

TOTO Entrada (Round)

  • Tight door-swing and knee clearance
  • An affordable route into TOTO flush quality
Not Ideal For
  • Shoppers who want a skirted, hidden trapway
  • Heavy-use family bathrooms wanting 1,000 g

The round front keeps the projection close to the wall, freeing the depth that decides whether a closet-sized bath is usable. Despite the small body, it runs a strong gravity flush at an efficient 1.28 gallons and carries EPA WaterSense certification, and a 10-inch rough-in version exists for older walls.

Owners report dependable single-flush performance and a low clog rate, and many note it is one of the cheaper ways to get genuine TOTO engineering. The 800-gram MaP score is strong rather than top-tier, so it suits a low-to-moderate-traffic bath more than a busy family bathroom.

Expert Take

When projection is the single number standing between you and a usable room, start here. The Entrada gives you real TOTO flush reliability in the shortest body the brand offers, and confirming the 10-inch rough-in version exists means it fits awkward older bathrooms a standard toilet cannot.

Bottom Line: The shortest-footprint round toilet here, ideal for the tightest powder rooms where every inch of depth counts.

  • Owners who dislike a two-piece seam
  • Buyers expecting the seat included

The taller seat sits at chair height for a more natural stand and sit, while the round bowl keeps the projection short, so you get the comfort without giving up the room. Its Class Five system posts a top-tier 1,000-gram MaP score at an efficient 1.28 gallons.

Owners praise the balance of a powerful flush, a low water figure and the kind of reliable, well-supported design Kohler is known for. If accessibility matters in your small bathroom, our roundup of the best toilets for seniors covers comfort-height options in more depth.

Expert Take

When a small bathroom is shared by taller adults or anyone who finds a low seat hard to use, this is the pick to start with. It is rare to find chair-height comfort and a short round projection in the same body, and the flush is genuinely strong.

  • A design-forward bathroom
  • Owners who want a skirted look

It posts a high 1,000-gram MaP score and clears the bowl with a forceful flush at an efficient 1.28 gallons. The round bowl keeps the projection short, and the wide trapway resists the clogs that plague many budget toilets, with a 10-inch rough-in option for older walls.

Contractors reach for Gerber in rentals and basements precisely because it is dependable and inexpensive to maintain. If your priority is a compact round bowl with a genuinely strong flush and you do not need designer styling, the Viper delivers more than its modest price suggests.

Expert Take

For a landlord or anyone fitting out a basement half bath in a small footprint, this is the smart-money round toilet. You get a 1,000-gram flush and a wide, clog-resistant trapway for the least outlay, with parts any plumber can source.

Not Ideal For
  • Strict low-flow households (1.6 GPF)
  • Quiet-flush priorities

The oversized 4-inch flush valve and extra-wide 2-3/8-inch trapway move waste with force, which is why owners with a history of clogs single it out. The round-front body keeps the projection short, so you get that power without a long footprint.

The trade-off is water and noise: at 1.6 gallons it uses more than the WaterSense picks, and the powerful flush is louder. For a small bathroom that handles real volume, though, the near-zero clog rate is often worth it.

Expert Take

Reach for the Champion 4 when a small bathroom takes heavy use and you are tired of plunging. It is not the most efficient or quietest choice here, but few round toilets are this hard to clog, and the round body keeps the footprint short.

Reliable Workhorse

Kohler Highline (Round)

Not Ideal For
  • Buyers chasing a top-tier 1,000-gram flush
  • Owners who want a seamless one-piece

The round Highline keeps the projection short while pairing a comfort-height seat with Kohler's Class Five system, which posts a strong 800-gram MaP score at an efficient 1.28 gallons. It is one of the most widely stocked toilets in the country, so flappers, fill valves and seats are easy to find.

Owners describe it as the toilet they install and forget, with a flush that rarely needs a second pull and a reputation for going years without issues. It is not the strongest flusher here, but the balance of reliability, comfort height and parts availability makes it a safe small-bathroom choice.

Expert Take

If you want a round toilet that simply works and is trivial to service, the Highline is the low-risk pick. It will not top the MaP chart, but for a typical small bathroom that does not see punishing traffic, its 800-gram flush and ubiquitous parts make it hard to regret.

Bottom Line: A reliable, easy-to-service round toilet that fits a small bathroom and rarely gives owners trouble.
Gerber Avalanche round toilet

Best Dual Flush Budget

Gerber Avalanche (Round)

4.3 Water savings on a budget

The Gerber Avalanche pairs a round-front body with a dual-flush button, giving a small bathroom meaningful water savings and a strong flush without the price of a premium brand.

  • A strong flush on a modest budget
  • Comfort-height seating in a short body
Not Ideal For
  • Design-forward, skirted bathrooms
  • Owners who want premium-brand support

The dual flush gives a light 0.8-gallon flush for liquids and a full 1.28-gallon flush for solids, which adds up to real water savings in a room used several times a day. Despite the budget price, it posts a top-tier 1,000-gram MaP score and keeps the projection short with its round bowl.

Owners praise the strong flush and the water savings, though a few note the plain styling and the need to occasionally tune the dual-flush valve. For a small bathroom where efficiency and a strong flush matter more than looks, the Avalanche is a lot of toilet for the money.

Expert Take

Choose the Avalanche when a small, busy half bath is quietly running up the water bill and you do not want to pay TOTO money to fix it. The 1,000-gram MaP score paired with a 0.8-gallon light flush is an unusually efficient, strong combination at this price.

Check price on Amazon
Bottom Line: A strong, water-smart dual-flush round toilet that saves money in a busy small bathroom without a premium price.
Expert Take

Across all nine picks, the pattern is clear: choosing a round-front bowl is the single biggest lever for cutting projection in a small bathroom, and it costs you nothing in flush power. The round TOTO Drake, American Standard Cadet 3, Kohler Cimarron, Gerber Viper and Champion 4 all post 1,000 grams on the MaP test in a short body. Buy the shortest round body that hits your MaP target, confirm the rough-in, and only then worry about styling or one-piece versus two-piece.

What Is the Smallest Toilet for a Small Bathroom?

The smallest toilets for a small bathroom are round-front models, which project roughly 25 to 27 inches from the wall versus 29 to 31 inches for an elongated bowl. The round TOTO Entrada and round versions of the American Standard Cadet 3 and Gerber Viper are among the shortest, and several offer a 10-inch rough-in version for even tighter older walls. Wall-hung toilets save the most floor space of all but require an in-wall carrier and a more involved install.

Are Round Toilets Better for Small Bathrooms Than Elongated?

Yes, round toilets are better for small bathrooms because the round bowl projects three to five inches less from the wall than an elongated bowl, which frees the floor depth and door clearance a tight room needs. Elongated bowls are more comfortable for many adults, so they are the better choice only when a small bathroom is narrow but has depth to spare. When floor depth is the constraint, a round bowl wins.

How to Choose a Round Toilet for a Small Bathroom

Buying a round toilet for a small bathroom is really an exercise in measuring carefully before you fall for a look. The checks below cover the mistakes that lead to a return, or to a toilet that technically fits but makes the room miserable to use.

Measure rough-in and projection before anything else

Two numbers decide whether a round toilet works in your space. The rough-in is the distance from the finished wall to the center of the floor bolts, and most homes are 12 inches, though 10 and 14 inch rough-ins exist in older or unusually laid-out spaces, so confirm yours before you shop our picks for every bathroom. The bowl projection is how far the toilet sticks out from the wall once installed. Round-front bowls typically project 25 to 27 inches and elongated bowls 29 to 31 inches. In a small bathroom those inches decide whether a door clears the bowl, so measure the actual open floor area and the door swing before you buy.

Use the round bowl to reclaim the most depth

The round-front bowl is the whole reason these toilets suit a small bathroom. It shaves a few inches off the projection so the toilet does not crowd a vanity, a door or your knees. Elongated bowls are more comfortable for many adults, so if your space is narrow but has depth to spare, a compact-elongated model keeps most of that comfort while staying reasonably short. When the constraint is overall floor depth, go round without hesitation, because the comfort gap between a modern round bowl and an elongated one is smaller than most shoppers expect.

Check side clearance and the 10-inch rough-in option

Plumbing codes generally require at least 15 inches from the center of the toilet to any side wall or fixture. In a genuinely small bathroom, a narrower tank and bowl help you hit that gap, so check the overall width on the spec sheet, not just projection. If your bathroom is in an older home, look for models that publish a 10-inch rough-in version, including the round TOTO Entrada, American Standard Cadet 3 and Gerber Viper, because a standard 12-inch toilet will not seal correctly on a 10-inch rough-in.

Do not trade flush strength for a smaller body. A round toilet does not have to mean a weak flush. Most of our short-footprint picks rate 800 to 1,000 grams on the independent MaP test, the same as full-size power toilets. Flush power comes from bowl geometry, trapway size and the flush valve, not overall footprint. Check the MaP score and aim for 1.28 GPF with EPA WaterSense certification so you get a strong, efficient flush in a body that fits.

Match the toilet to how the small bathroom is used

A guest powder room and a daily-use second bathroom have different needs even when they share the same dimensions. For a low-traffic half bath, a dual-flush model like the Gerber Avalanche saves water and a simple workhorse like the Kohler Highline keeps things easy. For a small bath that gets heavy daily use, lean toward a higher MaP score and a proven low-clog design like the round Champion 4, Drake or Cadet 3. If your small bathroom is the primary bath shared by the whole household, our guides to the most reliable toilets for daily use and the best toilets for large families cover the heavy-duty options worth considering.

Expert Take

Resist the urge to choose by appearance first. In a small bathroom, the order of operations is rough-in, then projection and door swing, then MaP score, and only then styling. Buy the shortest round body that still posts an 800-gram or higher MaP score, confirm whether you need a 10-inch rough-in version, and you will get a room that feels open and a flush you never have to repeat.

What Is a Good MaP Score for a Round Toilet?

A good MaP score for a round toilet is 600 grams or higher, with 800 to 1,000 grams considered strong. MaP testing measures how many grams of solid waste a toilet clears in a single flush, and 350 grams is the minimum residential pass set in cooperation with EPA WaterSense. A round bowl does not lower this number, so aim for at least 600 grams in a low-traffic powder room and 800 grams or more in a small bath that sees daily use.

Which Round Toilet Offers the Best Value?

The round American Standard Cadet 3 offers the best value because it pairs a top-tier 1,000-gram MaP flush with a short body, an EPA WaterSense 1.28-gallon rating and a stain-resistant EverClean surface, all at a budget-friendly price. The round Gerber Viper is the cheapest strong alternative, also posting a 1,000-gram flush and a wide, clog-resistant trapway for even less money in rentals and basements.

FAQ

Frequently Asked Questions

? What is a round toilet?

A round toilet has a round-front bowl, which is shorter and more circular than an elongated bowl. It projects roughly 25 to 27 inches from the wall versus 29 to 31 inches for an elongated model, so it takes up less floor depth. That shorter footprint is exactly why round toilets are the standard recommendation for small bathrooms, powder rooms and tight half baths.

? Are round toilets better for small bathrooms?

Yes. A round-front bowl projects three to five inches less from the wall than an elongated bowl, which frees the floor depth and door clearance a small bathroom needs. Unless your space is narrow but deep, a round bowl is the better choice because it keeps the room comfortable to walk into and lets the door swing clear of the seat.

? Do round toilets flush as well as elongated ones?

They can. Flush strength comes from bowl geometry, trapway size and the flush valve, not bowl shape. Several round models, including the TOTO Drake, American Standard Cadet 3 and Gerber Viper, rate a top-tier 1,000 grams on the independent MaP test, matching full-size power toilets. Check the MaP score rather than assuming a round bowl flushes weakly.

? How much smaller is a round toilet than an elongated one?

A round-front bowl typically projects about three to five inches less from the wall than an elongated bowl. In practice that means a round toilet sticks out roughly 25 to 27 inches while an elongated one reaches 29 to 31 inches. In a small bathroom, those inches often decide whether a door clears the seat or whether your knees press against a facing vanity.

? What is the shortest-projection round toilet?

The round TOTO Entrada has one of the shortest projections in any major lineup, and round versions of the American Standard Cadet 3, Kohler Cimarron and Gerber Viper all keep the bowl close to the wall while posting strong MaP scores. Always measure your open floor depth and door swing, then match it to the published projection on the spec sheet.

? What rough-in do I need for a small bathroom?

Most homes use a 12-inch rough-in, measured from the finished wall to the center of the floor bolts, but 10-inch and 14-inch rough-ins exist in older or unusually laid-out bathrooms. Measure yours before buying, because a 12-inch toilet will not seal correctly on a 10-inch rough-in. The round TOTO Entrada, American Standard Cadet 3 and Gerber Viper all publish 10-inch rough-in versions for tighter walls.

? Is a one-piece or two-piece round toilet better for a small bathroom?

Either works. One-piece round toilets like the Kohler Santa Rosa are easier to clean because there is no seam, which helps in a cramped space, but they are heavier to install. Two-piece models like the TOTO Drake and Kohler Highline cost less and are lighter to handle. Base the decision on projection and MaP score first, then choose the body style you prefer.

? Are round toilets available in comfort height?

Yes. The round Kohler Cimarron, Gerber Viper and American Standard Cadet 3 all come in comfort-height configurations, pairing a taller, chair-height seat around 16.5 to 17 inches with a short round bowl. Comfort height refers to seat height, not footprint, so it does not add depth or width to a small bathroom.

? How much floor space does a round toilet need?

Most plumbing codes call for at least 15 inches from the center of the toilet to any side wall or fixture, and a minimum of 21 inches of clear space in front of the bowl. A round toilet with its short projection makes hitting these clearances much easier, which is why bowl shape and projection matter more than overall size in a small bathroom.

? Are round toilets less comfortable than elongated?

Round bowls are slightly smaller on the seat, which some adults notice and others never do. Modern round bowls are larger and more comfortable than older designs, and the difference is smaller than most shoppers expect. In a small bathroom where depth is tight, the comfort trade-off is usually well worth the floor space a round bowl reclaims.

? Do round toilets save water?

They can, and most modern round models do. Look for an EPA WaterSense label and a 1.28-gallons-per-flush rating, which uses about 20 percent less water than the 1.6-gallon federal maximum. Bowl shape does not affect water use, so a round toilet with the right rating is just as efficient as an elongated one. The round Gerber Avalanche even adds a dual-flush button for extra savings.

? What is the best round toilet overall?

The round TOTO Drake is the best round toilet for most small bathrooms, pairing a short projection with a powerful G-Max gravity flush that posts a top-tier 1,000-gram MaP score at an efficient 1.28 gallons. It balances flush power, reliability, water efficiency and parts availability better than any other round model on our list.

? Which brands make the best round toilets?

TOTO, Kohler and American Standard lead for round toilets, with strong value options from Woodbridge, Swiss Madison and Gerber. These brands publish full specs and post reliable MaP scores, so you can match a short round body to a proven flush. TOTO and American Standard in particular offer the widest range of round-front and 10-inch rough-in models.

? How do I keep a round toilet from clogging?

Choose a model with a MaP score of 800 grams or higher and a wide, fully glazed trapway, such as the American Standard Champion 4, Gerber Viper or round Cadet 3. Avoid flushing wipes or excess paper, and in a low-traffic powder room use the full flush rather than a light dual-flush setting for solids. Trapway design matters more than bowl shape for clog resistance.

? Are wall-hung toilets a good option for a small bathroom?

Wall-hung toilets save the most floor space because the tank hides inside the wall and the bowl appears to float, freeing the floor beneath. They cost more and require an in-wall carrier and more involved installation, so they suit a full remodel rather than a quick swap. For most shoppers, a short-projection round floor model is the simpler space-saving choice.

? What is the best value round toilet?

The round American Standard Cadet 3 is the best value, pairing a top-tier 1,000-gram MaP flush with a short body and a stain-resistant EverClean surface. The round Gerber Viper is the budget alternative for rentals and basements, offering a similar 1,000-gram flush and a wide trapway for even less.

? Does WaterSense certification matter for a round toilet?

Yes. EPA WaterSense certification means the toilet uses 1.28 gallons per flush or less while still passing flush-performance standards, saving water and money over the life of the toilet. In a small bathroom that often doubles as a busy half bath, those per-flush savings add up quickly across a year.

? Can a round toilet still be heavy-use rated?

Yes. The round American Standard Champion 4, TOTO Drake and Cadet 3 all keep a short projection while posting 1,000-gram MaP scores and wide trapways built for frequent use. A small bathroom does not force you into a weak flush, so if the bath takes real traffic, prioritize a high MaP score and a wide trapway over styling.

? Do round toilets come with a seat included?

Many do not. Premium models like the TOTO Drake, TOTO Entrada and Kohler Cimarron often sell the seat separately, while several Woodbridge, Swiss Madison and Gerber models include a soft-close seat in the box. Check the listing before buying, and factor a round seat into your budget since round and elongated seats are not interchangeable.

? Is a round or elongated toilet seat needed for a round toilet?

A round toilet needs a round seat, which is shorter front to back than an elongated seat. The two are not interchangeable, so confirm the bowl shape before buying a replacement seat. Round seats are widely available in soft-close and standard versions, and they typically cost a little less than elongated seats.

Our Verdict

For most small bathrooms the round TOTO Drake is the best round toilet, pairing a short projection with a top-tier 1,000-gram G-Max flush at an efficient 1.28 gallons. Choose the round American Standard Cadet 3 for the best value, the round Kohler Santa Rosa for the cleanest one-piece, the round TOTO Entrada when projection is the constraint, the round Kohler Cimarron for comfort height, the round Gerber Viper for the least money, the round Champion 4 when a small bath still takes heavy use, the round Kohler Highline for set-and-forget reliability, and the round Gerber Avalanche for dual-flush water savings on a budget. Measure your rough-in and projection first, aim for an 800-gram or higher MaP score, and any pick here will keep a small bathroom open and usable for years.
