The TOTO Neorest RH and the Kohler Veil are the two integrated smart toilets most luxury buyers end up weighing against each other. Both are one-piece, tankless designs from major plumbing brands, both bundle a heated seat, warm-water bidet, dryer, and self-cleaning wand into a sealed unit, and both sit firmly in the four-figure-and-up tier. This is not a question of whether either is good — they both are. It's a question of whether you're buying the most advanced self-cleaning system on the market or the best-looking toilet in the room.
The core difference comes down to philosophy. TOTO is the company that invented the modern washlet, and the Neorest is its flagship — the toilet where hygiene technology is the headline. Its EWATER+ system sanitizes the bowl and wand between uses automatically, and the powered Tornado dual flush is engineered for thorough, reliable clearing. The Kohler Veil leads with design: a sleek, low-slung tankless silhouette that's widely considered one of the best-looking smart toilets you can buy, with the heated seat, warm-water wash, dryer, and self-cleaning wand you'd expect at this price. Both are premium; they just put their money in different places.
| TOTO Neorest RH | Kohler Veil | |
|---|---|---|
| Price | $4,400–$5,100 | $3,500–$6,000 depending on retailer and finish |
| Flush & performance | Powered Tornado dual flush — centrifugal rinsing action engineered for strong, thorough single-flush clearing | Tankless powered dual flush; reliable clearing, though TOTO's Tornado flush is the more celebrated system |
| Self-cleaning tech | EWATER+ auto-sanitizes bowl and wand with electrolyzed water; PREMIST wets the bowl before use — the most complete hygiene automation here | Self-cleaning wand that rinses itself; effective, but no electrolyzed-water bowl sanitizing equivalent to EWATER+ |
| Bidet wash & comfort | Instant tankless warm water, heated seat, warm-air dryer, deodorizer, oscillating/pulsing wash modes, multiple user settings | Warm-water bidet, heated seat, warm-air dryer, adjustable spray and position — strong comfort set, slightly fewer fine-tuning extras than the Neorest |
| Design & auto features | Full auto open/close lid and auto flush; refined but more traditional flagship styling | Full auto open/close and auto flush in one of the sleekest, lowest-profile tankless designs on the market — the styling is the standout |
| Reliability / brand | TOTO — the category originator with the deepest track record in electronic toilets and strong long-term build reputation | Kohler — a major, trusted US plumbing brand with wide support and a strong reliability record |
When to choose each
Choose the TOTO Neorest RH if hygiene technology and flush performance are what you're paying for. EWATER+ sanitizing the bowl and wand automatically between uses is the most complete self-cleaning system in this comparison, the PREMIST function means less sticks to the bowl in the first place, and the powered Tornado dual flush is the most celebrated flush in the category. It's also the pick if you want the deepest track record in electronic toilets — TOTO has been refining the washlet longer than anyone — and you value that engineering pedigree for a fixture you expect to keep for a decade or more.

The low-slung tankless silhouette is genuinely striking, the full auto open/close and auto flush deliver the hands-free experience, and you still get the heated seat, warm-water wash, and dryer that define the tier. With its price able to dip below the Neorest at the right retailer, it's also the pick for buyers who want flagship looks and core smart features without committing to TOTO's top-tier hygiene tech — and who'd rather put the budget into a fixture that anchors the bathroom's design.

Frequently asked questions
Is the TOTO Neorest worth the extra money over the Kohler Veil?
It depends on what you value. The Neorest's premium buys you the most complete self-cleaning system in the category — EWATER+ sanitizes the bowl and wand automatically, and PREMIST reduces buildup — plus TOTO's celebrated Tornado flush and the deepest track record in electronic toilets. If hygiene automation and flush performance are your priorities, yes, it's worth it. If you mainly want the look and the core smart features, the Veil delivers those for potentially less.
Does the Kohler Veil have anything like TOTO's EWATER+?
Not an exact equivalent. The Veil has a self-cleaning wand that rinses itself, which keeps the wash nozzle hygienic, but it doesn't have TOTO's EWATER+ system that electrolyzes tap water to sanitize the bowl and wand, and it doesn't have a PREMIST function that pre-wets the bowl. The Veil is hygienic and low-maintenance; the Neorest's automated hygiene simply goes a step further, which is a big part of its higher price.
Are both of these one-piece tankless toilets?
Yes. Both the TOTO Neorest RH and the Kohler Veil are one-piece, tankless integrated smart toilets, which is part of why both look so clean and modern compared to a traditional toilet with a tank. Both still need a 120V GFCI outlet nearby for power, both sit on a standard rough-in, and both are best installed by a plumber given their weight and the electrical connection. Tankless also means the flush is powered rather than gravity-fed, so adequate water supply pressure matters for both.
