Is the TOTO Neorest LS Worth It?
Yes — if your budget allows for it, the Neorest LS is absolutely worth the investment.
This is not a bidet seat you add to an existing toilet. It is a complete, one-piece smart toilet that replaces your entire fixture, and the experience it delivers reflects that. From the moment you walk into the bathroom, the lid opens on its own. The bowl premists. The heated seat is ready. When you are done, the toilet flushes and the lid closes — all without you touching anything.
If you have been browsing the bidet toilet seat comparison chart, looking for the best of the best, the Neorest LS is where that search ends. It is the kind of product that makes other bathrooms feel like a step backward.
Design & Build Quality
The Neorest LS has one of the most distinctive silhouettes in the luxury smart toilet market. Where most bidet toilets have soft, rounded forms, the LS goes in a completely different direction — sharp linear edges, straight lines, and a skirted base that hides the trapway completely for a seamless floor-to-seat look.
It is available only in Cotton White ceramic, but TOTO gives you a meaningful design choice with three accent trim options — Silver, Nickel, or Black — that extend to the matching remote control. This level of customization is rare in the category and makes it possible to match the unit to almost any modern bathroom aesthetic.
The unit ships in two separate parts — the bowl and the top unit — with a combined shipping weight of over 110 lbs. That means this is not a solo weekend install. You will want a licensed plumber and electrician involved, particularly because the Neorest LS draws up to 1,283 watts and ideally should be on a dedicated 20A GFCI circuit. If you are comparing it to a simpler seat-only upgrade like the TOTO Washlet S5, understand that this is a fundamentally different category of purchase — one that involves a full toilet replacement, not a seat swap.
The seamless seat design eliminates the gap between seat and lid where grime traditionally collects, and the lid itself can be removed for deep cleaning. Build quality is exactly what you would expect from the brand behind the highest rated bidet toilets in the industry — solid, premium, and built to last well beyond the 3-year residential warranty.
Cleaning Performance
This is where the Neorest LS genuinely separates itself from the competition, and the separation is not small.
Three layers of hygiene technology work in concert every single time you use the toilet. PREMIST® automatically sprays the inside of the bowl with water before you sit down, making the CEFIONTECT® glaze even more effective at preventing waste from adhering to the surface. CEFIONTECT® itself is TOTO’s ultra-smooth ionic barrier glaze — it works passively 24/7 to keep the bowl cleaner between scrubbing sessions.
Then there is EWATER+®, which is arguably the most advanced self-cleaning technology in the consumer bidet market. After every use, the system electrolyzes tap water into a mild sterilizing agent similar in properties to diluted bleach, then mists the wand, the underside of the seat, and the toilet bowl itself. You are not just rinsing — you are sterilizing, automatically, every time.
The result is a toilet that requires significantly less manual cleaning effort than any conventional toilet or even most other bidet toilets. Users consistently report that the bowl stays visibly cleaner for longer, and the wand maintenance concern that comes with many bidets for existing toilets is essentially eliminated here.
The TORNADO FLUSH® system completes the picture — dual nozzles create a centrifugal, cyclonic flush that covers the entire hole-free rim bowl without leaving dead spots. Between the 0.8 GPF and 1.0 GPF options, you are always getting a thorough flush with minimal water use.
Comfort Features
Comfort on the Neorest LS is not a feature — it is the entire philosophy of the product.
The heated seat offers five temperature levels, and because the Neorest LS uses an instantaneous tankless water heater, you get unlimited warm water during the cleanse from the very first second — no waiting, no running cold mid-wash. For anyone who has tried a tank-heated seat like older TOTO C-series models and experienced the warm water cutting out, this is a genuinely noticeable upgrade.
Six wash modes give you precise control: front wash, soft rear, rear, oscillating, pulsating, and wide front. Water temperature, pressure, and spray position are all adjustable. The warm air dryer has five temperature settings, and the integrated deodorizer activates automatically while you are seated. A bowl night light means no stumbling in the dark for late-night visits — a small feature that becomes surprisingly indispensable once you have it.
Four user memory presets make the LS genuinely practical for multi-person households. Each person saves their preferred seat temperature, water temperature, water pressure, and nozzle position into their own preset and calls it up with a single button press. If you have been comparing this to other heated bidet toilet seats, it is worth noting that most seat-only models max out at two presets — the Neorest LS doubles that.
Controls & Installation
The Neorest LS is controlled via an ergonomic wireless stick-style remote that comes in your choice of Silver, Nickel, or Black to match the toilet’s accent trim. The remote handles everything — lid, seat, wash mode, temperature, pressure, auto flush, and user preset selection.
The proximity sensor that triggers the auto-open lid works reliably and can be configured to open only the lid or both the lid and seat simultaneously. One real-world limitation that multiple users have noted is that the remote buttons are not backlit, which can make selecting the right button in a dark bathroom inconvenient. It is a minor complaint on a unit this capable, but it is honest feedback worth knowing before you buy.
Installation requires a 120V GFCI outlet within approximately 4 feet of the toilet’s placement, and the power cord runs 3.9 feet. The unit is ADA compliant with a universal comfort height seat at 17-5/16″ — accessible for seniors, people with mobility challenges, and users of all ages. If accessibility is a priority, our guide to the best bidets for seniors is worth a read alongside this review, as the Neorest LS ranks among the most accessible options available.
Who Is the TOTO Neorest LS Best For?
The Neorest LS is the right choice for you if you are renovating or remodeling and want the centerpiece of a truly premium bathroom, not just a bidet seat upgrade.
It suits buyers who want total hands-free automation, genuinely reduced cleaning burden, and a product that can comfortably serve the whole household with individual presets. It is particularly well suited to design-conscious buyers who appreciate the choice of trim finish and the sharp linear aesthetic that sets the LS apart from the rounder profiles of the Neorest AS and Neorest RS.
If you are comparing the Neorest LS to other best bidets for home use and budget is not the primary constraint, this unit consistently wins on automation depth, hygiene technology, and long-term cleaning convenience. It is also one of the few smart toilets that will look at home in a true luxury bathroom design — the trim options make a real difference in that regard.
FAQ
Does the TOTO Neorest LS replace the 700H model?
Yes. The Neorest LS is the direct successor to the TOTO Neorest 700H. It introduces EWATER+® spray under the seat (in addition to the bowl and wand), a seamless seat for easier cleaning, four user presets instead of two, a newer auto flush with closed-seat option, and warmer seat and dryer performance. If you had the 700H and loved it, the LS is a meaningful upgrade in nearly every area.
Does the Neorest LS fit a standard 12-inch rough-in?
Yes. The Neorest LS is designed for a standard 12-inch rough-in (wall to center of drain). This is the minimum required distance — if your rough-in is further from the wall, the toilet will simply sit further out, which is fine. Always confirm your rough-in measurement before ordering, and plan for professional installation since the unit ships as two freight pieces totaling over 110 lbs.
How does the EWATER+® system work on the Neorest LS?
EWATER+® works by electrolyzing ordinary tap water inside the unit, transforming it into a mild sterilizing agent with properties similar to diluted bleach — without any chemicals or additives required from you. After every use, the system automatically mists the wand, the underside of the seat, and the toilet bowl itself. About 25 seconds after flushing, the bowl receives another EWATER+® mist. The result is ongoing automated sanitation that substantially reduces the amount of manual scrubbing your toilet needs. It is the same technology found in TOTO’s WASHLET seats like the S2 and S5, but extended here to cover under the seat as well.
How does the Neorest LS compare to the Neorest RS?
The Neorest RS has a softer, more rounded profile, no trim finish options, and a side panel design. The LS goes further with sharp linear edges, a completely smooth seamless ceramic base with no side panel, decorative trim choices (Silver, Nickel, or Black), and a slightly larger footprint that feels more spacious to sit on. The LS also replaced the 700H as TOTO’s premium-tier Neorest, making it the current top-of-line standalone Neorest model before the NX2. If design and automation depth matter to you, the LS is the clear step up. You can also compare integrated options in our best toilets with bidet roundup.
Conclusion
The TOTO Neorest LS earns its position at the top of the luxury smart toilet market through sheer depth of automation, hygiene technology, and build quality.
The fully hands-free experience — from the auto-open lid greeting you to the EWATER+® mist that follows your flush — sets a standard that very few products in any category can match. The instantaneous warm water, six wash modes, four user presets, and the choice of decorative trim finishes make it genuinely personal in a way that most premium toilets are not.
The honest trade-offs are the high price, the professional installation requirement, and the non-backlit remote. None of those change what this toilet actually delivers day to day — which is an experience so refined it makes everything else feel ordinary by comparison.
