The Kohler Veil is the toilet you reach for when you want a fully integrated bidet, a heated seat and a tankless, wall-hugging body that flushes on demand without a bulky tank. It is built on a tankless electric flush that pulls pressurized line water through a swirl-style rinse, paired with a warm-water washlet, an air dryer, a heated seat and a remote that controls all of it. This review compares the Veil's published specifications, its dual-flush water-use figures, EPA WaterSense certification, the engineering behind its tankless flush, and the recurring themes across thousands of aggregated owner reviews, so you can decide whether this integrated smart toilet earns a place in your bathroom.
Research updated June 2026.
The Kohler Veil is our top pick for buyers who want a fully integrated smart toilet with a tankless body, warm-water bidet, heated seat and dual-flush efficiency in one seamless skirted unit. Its tankless electric flush uses just 0.8 and 1.28 gallons, carries EPA WaterSense certification, and the spa features rival a TOTO Washlet built into the bowl itself.
The Kohler Veil is one of those toilets that sells on what it does for you, not just how it clears the bowl. From the outside it is a compact, fully skirted one-piece with a low, tankless profile that hugs the wall and photographs like a piece of modern furniture rather than plumbing. There is no traditional tank rising behind the seat, because the Veil flushes electrically using pressurized water from your supply line. Built into the body are a warm-water bidet wand with adjustable position and pressure, a warm-air dryer, a heated seat, a deodorizer, a nightlight and an automatic open-and-close lid on many configurations, all driven by a wireless remote. The Veil is aimed squarely at the buyer who wants the spa experience of a Japanese smart toilet without bolting a separate washlet seat onto an ordinary bowl.
This review looks past the showroom appeal and at the engineering and data that actually predict how an integrated smart toilet performs. We compare the Veil's published specifications (flush method, dual-flush water volumes, trapway, bowl shape, rough-in and electrical needs), how its tankless flush behaves against gravity rivals, its WaterSense certification and gallons-per-flush figures, the bidet and seat feature set, and the consistent patterns across thousands of aggregated owner reviews covering flush strength, bowl rinsing, the washlet, reliability and the realities of living with an electric toilet. Where the Veil has genuine weaknesses, we name them plainly. To see how it stacks up against the whole field, our pillar roundup of the best flushing toilets places integrated smart toilets like the Veil alongside the strongest conventional flushers.
We do not install the Veil in a lab and flush it ourselves, and we will not pretend we do. Instead we read Kohler's published specifications, compare the Veil's flush method and water-use figures against rival toilets, factor in WaterSense certification and gallons per flush to reward power that stays efficient, study the bidet and heated-seat feature list, and read the recurring themes across thousands of aggregated owner reviews. No payment buys a favorable verdict on this page.

A note on model codes. The Veil intelligent toilet is most commonly sold as the K-5401 (the full collection is also listed under codes such as K-77795 for newer revisions and regional variants). It ships as a complete integrated unit, not a bowl-and-seat you assemble. Because it is an electric toilet, it requires a dedicated grounded GFCI electrical outlet behind or beside the unit, and the flush relies on a minimum supply-line water pressure that Kohler publishes in the spec sheet. Feature sets, lid automation and exact water-use figures vary slightly by revision, so always confirm the electrical requirement, the rough-in, the minimum water pressure and the included remote before you order.
Flush behavior on the Veil is fundamentally different from the gravity toilets most buyers know, so it is worth understanding before you commit. There is no tank of standing water waiting to be dumped. Instead, the Veil draws pressurized water directly from your supply line and an internal pump-and-valve system meters it through the rinse rim and jet on demand. When you press the remote, the toilet releases a measured, swirling rush of line water that washes the bowl and drives the siphon. The upside is a compact, tankless body with no tank to refill between flushes and no tank condensation to wipe down. The trade-off is that the flush depends on adequate household water pressure and on electrical power, so the Veil behaves differently than a self-contained gravity bowl.
Because the Veil is an integrated electric toilet rather than a standalone bowl, it is not graded in the standard MaP (Maximum Performance) gram test the way a TOTO Drake or Kohler Cimarron is, so there is no single published gram figure to quote. What the specifications and aggregated owner reviews tell us is that the flush is engineered for a clean, efficient rinse on low water volumes rather than for clearing the absolute heaviest waste loads. Most owner reviews describe the flush as quiet and tidy, with the swirl rinsing the bowl evenly, and clogs uncommon in normal residential use. A minority of reviews note that on the lighter 0.8-gallon eco flush, heavier loads occasionally need a second cycle, which is the practical cost of a tankless design tuned for water savings.
The Veil is the toilet we recommend when a buyer wants the full spa experience of a heated seat and warm-water bidet built into one seamless, tankless body, and is willing to run power and confirm water pressure to get it. Treat the flush as a clean, efficient rinse rather than a brute-force clog clearer. If your bathroom clogs constantly or you want a maximum-rated gravity flush, a TOTO Drake with a separate Washlet seat is the more bulletproof path. If you want one integrated unit that looks and feels modern, the Veil delivers.
The Veil is a dual-flush toilet, using 1.28 gallons for the full flush and roughly 0.8 gallons for the light eco flush, and it carries EPA WaterSense certification. WaterSense certifies toilets that use at least 20 percent less water than the federal 1.6-gallon maximum while still passing flush-performance criteria, and the Veil clears that bar comfortably. Because most flushes in a typical household are liquid-only and can use the 0.8-gallon mode, average daily water use lands well below a single-flush 1.28-gallon toilet, and far below an older 1.6-gallon model. The bidet feature also reduces toilet-paper use, an indirect resource saving many owners value.
Over a year of normal household use that low average volume adds up to a meaningful water saving, and in regions that offer toilet rebates a WaterSense model can qualify, though buyers should confirm whether their local program covers integrated electric toilets. The Veil appears among the smart options in our roundup of the best flushing smart toilets, where its blend of dual-flush efficiency and integrated bidet features is exactly the balance buyers in that category want. For shoppers focused purely on the lowest water use, our guide to the best dual-flush toilets covers the wider field of efficient flushers.
The Veil earns its smart-toilet status by integrating features that are normally split across a bowl and an add-on seat. Instead of buying a conventional toilet and bolting a separate washlet on top, you get a single unit where the bidet wand, heated seat, dryer, deodorizer and flush are engineered to work together. Aggregated owner reviews are largely positive on the experience: buyers praise the warm-water cleansing, the heated seat in cold bathrooms, the quiet flush and the clean tankless look. The recurring caution is that, like any electronic toilet, it adds complexity a basic gravity bowl does not have, which we cover honestly in the reliability section below.
The feature list is the reason most buyers shortlist the Veil. The bidet wand offers warm water with adjustable spray position, water pressure and temperature, plus an oscillating mode, and it self-cleans before and after use. The heated seat has multiple temperature settings, which owners in cold climates consistently single out as the feature they would not give up. The warm-air dryer reduces or eliminates the need for paper, the carbon deodorizer manages odor at the source, and a soft nightlight helps with late-night trips. On lid-automation versions, a motion sensor opens the lid as you approach and closes it after, and an auto-flush option triggers the rinse when you step away. A wireless remote, and on some revisions a companion app, controls the settings. For buyers comparing standalone bidet upgrades instead, our guide to the best bidet toilet seats covers the add-on route.
Styling is where the Veil clearly justifies itself against plainer, more powerful rivals. The tankless one-piece body is low and compact, with a fully skirted form that conceals the trapway and a continuous, seamless surface that wipes clean in a single pass. With no tank rising behind the seat, the Veil takes up less front-to-back depth than most conventional toilets, which makes it a genuine option for tight or modern bathrooms where a traditional tank would dominate. The absence of a tank also means no tank-to-bowl seam to scrub and no tank sweating in humid weather, two cleaning headaches that disappear entirely.
On bowl cleaning, the swirl-style rinse and the self-cleaning bidet wand both help keep maintenance down, and many owner reviews note that the integrated design leaves fewer crevices to scrub than a conventional bowl with a bulky add-on seat. The Veil is typically offered at a comfortable, chair-like seating height that suits most adults and is easier on the knees and back than a low standard toilet, a benefit owners with mobility concerns appreciate. The one area that needs attention on any electronic toilet is the seat hinge and wand housing, where the electronics live, so wiping is preferred over harsh chemical soaks. For buyers weighing seamless bodies in general, our look at the best skirted toilets puts the Veil's tankless form in context.
Installation is more involved than a standard toilet, and buyers should plan for it. The Veil fits a standard rough-in (the distance from the finished wall to the center of the floor drain), but you must confirm the exact figure on Kohler's spec sheet for your revision before ordering. The two requirements that catch buyers off guard are electrical and water pressure. The Veil needs a dedicated, grounded GFCI electrical outlet within reach of the unit, so if there is no outlet near the toilet you will need an electrician to add one, which is the single most common installation cost owners mention. The flush also depends on a minimum incoming water pressure, published by Kohler, so homes with low static pressure should verify they meet it before buying.
Because the Veil is a complete integrated unit, you are not assembling a tank and bowl, but you are connecting water, power and the unit's own valves, so many buyers hire a plumber and, if needed, an electrician rather than going fully DIY. Parts and service flow through Kohler's network, which is a real advantage with an electronic product, since a no-name imported smart toilet can be hard to get parts for years later. The flip side is honest to state: an electronic toilet has more that can eventually need service than a simple gravity bowl, and in a power outage the manual flush option becomes important, so confirm your revision includes one. Check the current price on Amazon to see where the Veil lands today against standalone washlet pairings.
Reliability is the question every smart-toilet buyer should ask, and the honest answer is mixed but reasonable. Aggregated owner reviews skew positive on the day-to-day experience, with the bidet, heated seat and quiet flush drawing consistent praise. The criticisms cluster around the realities of an electronic product: a small share of reviews mention remote or sensor quirks, the need for a nearby outlet, and the fact that any warm-water bidet with a heated seat adds electronics that a plain toilet does not have. None of that is unique to the Veil, it is the trade-off inherent to every integrated smart toilet, including premium Japanese models.
The practical guidance is to weigh the spa features you will actually use against the added complexity and the install requirements. If a warm-water bidet and a heated seat would genuinely change how you feel about your bathroom, the Veil delivers them in a cleaner, more integrated package than bolting a separate washlet onto a basic bowl, and Kohler's parts network reduces the long-term risk. If you mostly care about raw flushing power and simplicity, a conventional gravity toilet will serve you with fewer things to ever go wrong. Buyers cross-shopping the category should also read our roundup of the best smart toilets for the broader field.
The Veil is the toilet to buy when you want a tankless, seamless body with a built-in warm-water bidet, heated seat and dual-flush efficiency in one unit, not a bowl with a bolted-on washlet.
The tankless flush meters pressurized line water through a swirl rinse on 1.28 or 0.8 gallons, so there is no tank to refill and no condensation to wipe, and the integrated bidet, dryer, heated seat and deodorizer run from a wireless remote. It is engineered for a clean, efficient rinse rather than brute force, with most owner reviews reporting quiet operation and few clogs in normal use.
Aggregated owner reviews are largely positive, with repeated praise for the warm-water cleansing, the heated seat in cold bathrooms and the seamless tankless styling. The most common criticisms are the dedicated-outlet and water-pressure requirements at install, occasional remote or sensor quirks, and the added complexity any electronic toilet carries versus a plain gravity bowl.
This is the toilet we recommend most often to buyers who want the full Japanese-style spa experience built into the bowl itself rather than added on top. Confirm you have a grounded outlet and adequate water pressure, accept the electronics trade-off, and the Veil rewards you with a clean, modern, genuinely pleasant toilet you stop thinking about.
Pairing a TOTO Washlet seat with a maximum-rated TOTO Drake gives you the strongest gravity flush plus warm-water bidet features, in a modular setup you can service piece by piece.
The Drake's 3-inch G-Max siphon jet grades a maximum 1000 grams on MaP, far above any tankless integrated unit, and the Washlet seat adds warm water, a heated seat and a dryer on top. The trade-off is a visible tank and a seat-on-bowl seam rather than the Veil's seamless tankless body.
Owner reviews praise this pairing as the most bulletproof way to get bidet features without trusting the whole toilet to electronics, since the simple gravity bowl keeps working even if the seat ever needs service. Our TOTO Washlet review and TOTO Drake review break down each half.
If maximum flushing power matters as much as the bidet, this modular pairing beats any tankless integrated toilet on raw clog clearing. Choose it over the Veil when you want simplicity and serviceability over a seamless one-piece look.
The Santa Rosa wraps Kohler's AquaPiston canister flush in a compact, seamless one-piece body, the choice when you want a clean Kohler one-piece without any electronics.
The AquaPiston canister releases water from all sides of the valve for a strong, efficient flush that grades a full 1000 grams on MaP, far simpler and more bulletproof than a tankless electric flush. The one-piece body removes the tank-to-bowl seam, so there is no gap collecting dust, and it needs no outlet or minimum water pressure to work.
Owner reviews highlight the clean look, quiet flush and easy maintenance, with no electronics to ever fail. For shoppers who like the Veil's seamless shape but not its complexity, our Kohler Santa Rosa review explains who it suits best.
Choose the Santa Rosa when you love the idea of a seamless Kohler one-piece but do not want to run power or trust electronics. It gives you a maximum-rated gravity flush in a clean body, leaving the bidet decision to a separate seat later if you want it.
Value in the smart-toilet category depends on whether you want one integrated unit or a modular bowl-plus-seat setup. The Veil's case is that everything is engineered to work together in a single seamless body, with no add-on seat seam and Kohler service behind it, which is worth a premium to buyers who prize the look and the integration. The modular path, a maximum-rated gravity bowl with a separate washlet, usually delivers more raw flushing power for the money and lets you replace just the seat if the electronics ever fail. Budget-focused buyers chasing the skirted smart-toilet look at a lower price should also weigh Swiss Madison's integrated and washlet options, which we cover in our roundup of the best smart bidet toilets.
When buyers describe wanting a spa-like bathroom with a heated seat and warm-water bidet in a clean, modern unit, the Veil is the one we point to first. Confirm the outlet and water pressure, decide whether you value seamless integration over modular serviceability, and the Veil's bundled features justify their premium for the right buyer. If you flush heavy loads constantly or want the simplest possible toilet, pair a Drake with a Washlet instead and accept the visible tank.
The Veil is the right call for homeowners and remodelers who want a fully integrated smart toilet with a warm-water bidet, heated seat and dual-flush efficiency in one seamless, tankless body, and who have or can add a nearby electrical outlet and adequate water pressure. It suits modern and compact bathrooms where a tank would dominate, rewards buyers who will actually use the spa features daily, and offers real peace of mind through Kohler's broad parts and service network compared with no-name imported smart toilets. The bidet and dryer also cut paper use, a benefit many owners come to value quickly.
You should look elsewhere if your bathroom has no outlet and you do not want to pay an electrician, if your home has low water pressure, or if you simply want the strongest, simplest gravity flush regardless of features, in which case a conventional Kohler or TOTO bowl, optionally with a separate washlet seat, serves you with fewer things to ever go wrong. Buyers who want maximum 1000-gram clog clearing should pair a TOTO Drake or American Standard Champion 4 with an add-on bidet seat rather than rely on a tankless integrated flush.

Yes, for buyers who want an integrated smart toilet. The Veil bundles a tankless dual-flush, warm-water bidet, heated seat, dryer and deodorizer into one seamless body, carries EPA WaterSense certification, and aggregated owner reviews praise the spa features and clean tankless look. The trade-offs are the install requirements and the added complexity of an electronic toilet.
Yes. The Veil is an electric toilet that requires a dedicated, grounded GFCI outlet near the unit to power the flush, bidet, heated seat and dryer. If there is no outlet nearby, you will need an electrician to add one. Confirm your revision includes a manual flush backup for power outages before buying.
The Veil is tankless, so instead of dumping a tank of standing water it draws pressurized water directly from your supply line and meters it through a swirl rinse on demand. This needs adequate household water pressure, which Kohler publishes, but it removes the bulky tank, the refill wait and the tank condensation entirely.
The Veil is a dual-flush toilet using 1.28 gallons for the full flush and roughly 0.8 gallons for the light eco flush, and it is EPA WaterSense certified. Because most flushes can use the lighter mode, average daily water use lands well below a single-flush 1.28-gallon toilet and far below an older 1.6-gallon model.
Yes, the Veil carries EPA WaterSense certification. The program certifies toilets that use at least 20 percent less water than the federal 1.6-gallon maximum while still passing flush-performance criteria. The Veil's dual-flush 1.28 and 0.8-gallon volumes clear that bar comfortably, and its bidet feature also reduces paper use.
The Veil is an integrated tankless electric toilet, so it is not graded in the standard MaP (Maximum Performance) gram test the way conventional gravity bowls like the TOTO Drake are. There is no single published gram figure. Owner reviews describe the flush as a clean, efficient rinse rather than a maximum-force clog clearer.
Yes. The Veil has a built-in warm-water bidet wand with adjustable spray position, water pressure and temperature, plus an oscillating mode, and it self-cleans before and after use. The bidet is integrated into the toilet itself rather than added as a separate washlet seat, which is the main reason buyers choose it.
Yes, the Veil includes a heated seat with multiple temperature settings, controlled by the wireless remote. Owners in cold climates consistently single out the heated seat as the feature they would not give up. It is one of the spa features built into the integrated body alongside the bidet and dryer.
Yes, the Veil ships with a wireless remote that controls the flush, bidet, heated seat, dryer and other settings, and some revisions add a companion app. Confirm the included remote and any app support for your specific revision on the product page before ordering.
Many Veil configurations include an automatic lid that opens as you approach via a motion sensor and closes after use, and some add a hands-free auto-flush. Lid automation and auto-flush vary by revision, so confirm whether the model you are buying includes these features before ordering.
It is more involved than a standard toilet. You must connect water and power, and the Veil needs a dedicated grounded GFCI outlet and adequate water pressure. Many buyers hire a plumber and, if no outlet exists, an electrician. Confirm the rough-in, the electrical requirement and the minimum water pressure on Kohler's spec sheet first.
The Veil fits a standard rough-in, the distance from the finished wall to the center of the floor drain, but the exact figure can vary by revision, so confirm it on Kohler's spec sheet before ordering. Measure carefully and verify your bathroom matches before committing to an integrated unit.
Clogs are uncommon in normal residential use, and the swirl rinse keeps the bowl clean. The honest caveat is that on the lighter 0.8-gallon eco flush, heavier loads occasionally need a second cycle, which is the trade-off of a tankless design tuned for water savings. For chronically heavy loads, a maximum-rated gravity bowl offers more margin.
Because the Veil is an electric toilet, you should confirm your revision includes a manual flush option for power outages, which most do. The bidet, heated seat and dryer will not work without power, but a manual flush keeps the toilet usable. This is a key reason to verify the backup-flush feature before buying.
The Veil is a fully integrated, tankless one-piece unit, meaning it is a single seamless body rather than a separate tank and bowl. It ships as a complete unit, not parts you assemble, which gives it the clean, low profile that suits modern and compact bathrooms.
The Veil is a fully integrated tankless smart toilet with the bidet built into the body, while a TOTO Washlet is a seat you add to a separate bowl. The Veil wins on seamless integration and compact tankless looks. A Washlet on a TOTO Drake wins on raw flushing power and piece-by-piece serviceability. Choose based on whether you value integration or simplicity.
Yes, the tankless body is one of the Veil's biggest advantages in tight spaces. With no tank rising behind the seat, it takes up less front-to-back depth than most conventional toilets and presents a clean, low profile. That makes it a genuine option where a traditional tank would dominate the room.
Aggregated owner reviews skew positive on day-to-day use, with the bidet, heated seat and quiet flush drawing consistent praise. Like any electronic toilet, it adds complexity a plain gravity bowl does not have, and a small share of reviews mention remote or sensor quirks. Kohler's parts and service network reduces long-term risk compared with no-name imports.
Yes. The Veil includes a warm-air dryer that reduces or eliminates the need for paper and a carbon deodorizer that manages odor at the source. Combined with the warm-water bidet and heated seat, these round out the integrated spa experience that buyers choose the Veil for.
For buyers who will use the warm-water bidet and heated seat daily and want them in one seamless tankless body, yes. The Veil costs more than a conventional toilet, but it bundles features that would otherwise require a bowl plus a separate washlet, and Kohler's parts network backs it. If you mainly want flushing power per dollar, a Drake plus a Washlet seat may serve you better.
The Kohler Veil is the toilet we recommend first to buyers who want a fully integrated smart toilet, with a warm-water bidet, heated seat, dryer and deodorizer built into one seamless, tankless body rather than bolted on as a separate washlet. Its tankless electric flush meters pressurized line water through a swirl rinse on an efficient, WaterSense-certified 1.28 and 0.8 gallons, and aggregated owner reviews back the experience up with praise for the spa features and the clean, compact look. The honest trade-offs are real: it needs a dedicated outlet and adequate water pressure, it carries the added complexity of any electronic toilet, and it is not a maximum-force gravity clog clearer, so heavy-load bathrooms may prefer a Drake paired with a Washlet seat or a 1000-gram gravity bowl like the Cimarron or Champion 4. But for a modern bathroom where you want the integrated spa experience in one tankless unit backed by Kohler's parts network, the Veil is one of the smartest picks in the category. Check the current price on Amazon to see where it sits today.
