Is the TOTO NEOREST RS Worth It?
Yes — if you’re ready to commit to a complete toilet upgrade and want the most automated bathroom hygiene experience available at the entry point of the Neorest lineup.
The RS delivers the full Neorest package: touchless auto open/close lid, auto flush, PREMIST bowl misting before every use, EWATER+ wand and bowl sanitization after every use, instantaneous warm water, and a 5-setting heated seat — all in one sleek, integrated unit.
What makes it particularly compelling at this tier is the three-year residential warranty, which is exceptional for an integrated smart toilet and reflects the engineering confidence behind the product.
The RS replaced the now-discontinued TOTO Neorest RH and brings two meaningful upgrades to that platform: four user memory presets instead of two, and a redesigned block-style remote with a more intuitive layout.
If you’re considering any bidet seat in the upper-mid to premium range, it’s worth asking whether you’d rather upgrade your entire toilet to the RS instead — the integration, hygiene technology, and cleanup story are significantly better than anything you can achieve by adding a seat to an existing toilet.
For a broader look at where the RS sits in the smart toilet landscape, the guide to the highest-rated bidet toilets is a useful starting point.
Design and Build Quality
The Neorest RS has what TOTO describes as an organic design — smooth, rounded curves and a sloping silhouette with no sharp corners.
It’s the softer-looking of the two new Neorest models, sitting in contrast to the more angular, contemporary lines of the step-up Neorest AS.
The skirted trapway conceals all plumbing lines for a completely seamless exterior, and the seamless seat design eliminates the dust-collecting gap that plagues conventional toilets and even most bidet seats.
The entire ceramic surface is coated with CEFIONTECT — TOTO’s nanoscale glaze that seals the porous surface and makes it genuinely difficult for waste to bond to the bowl.
Combined with PREMIST, which pre-wets the bowl with water before every use, you’ll find you need to scrub far less frequently than you ever did with a conventional toilet.
At 27-1/8″ L × 15-1/4″ W × 21-1/2″ H, the RS has a larger footprint than a typical consumer-grade toilet, so checking your bathroom rough-in dimensions before ordering is essential.
The Universal Height seat at 17-11/16″ from floor to seat is genuinely comfortable for a wider range of adults than the lower seat heights found on older toilet designs — and the ADA compliance makes it a practical choice for households with elderly users or anyone with limited mobility.
If accessibility is a priority, the best bidets for seniors guide covers what to look for in more detail.
Flushing and Bowl Cleaning
The TORNADO FLUSH system uses 360° rimless cleaning power — water spirals around the entire inner surface of the hole-free rim bowl, leaving no dry patches or hard-to-reach corners where waste could linger.
The dual flush gives you the choice of 1.0 GPF for solid waste and 0.8 GPF for liquid, which translates to measurable water savings over the life of the toilet compared to older 1.6 GPF models.
Auto flush activates as soon as you rise from the seat, with a manual backup override on the remote in case of power outages — a sensible and reassuring design choice that keeps the toilet fully functional even without electricity.
The EWATER+ system activates after each flush to mist both the wand and the inner bowl surface with electrolyzed water — a natural sanitizing agent that breaks down bacteria without any chemical cleaners.
In practice, owners consistently report that bowl cleaning sessions become far less frequent and far easier than with any conventional toilet — which is exactly what the PREMIST and CEFIONTECT combination is engineered to do.
Bidet and Comfort Features
The integrated bidet wand delivers five fully adjustable cleanse modes — rear, soft rear, front feminine, oscillating, and pulsating — with independent water pressure and temperature controls for each.
The instantaneous water heater means warm water is available from the very first second of your wash, with no waiting and no running cold mid-session regardless of how long you wash or how many consecutive users follow you.
This is a meaningful advantage over tank-style heated bidet seats, which are limited to whatever volume of pre-heated water sits in the reservoir — usually enough for 30 to 60 seconds before cooling.
If you’ve been comparing bidet seats and wondering what separates them from a fully integrated unit like the Neorest RS, the bidet toilet seat comparison chart gives you a useful reference point for what the best seats can do — and the RS does all of it, built in.
The four-user memory preset system on the remote lets each household member save their preferred temperature, pressure, spray position, and seat warmth — one button on the block-style remote retrieves all of their settings at once.
The heated seat warms automatically as you approach the toilet, and the air deodorizer uses a filter-only system — no synthetic fragrances sprayed into the air, just odor neutralization as it happens.
For families with multiple users or seniors who benefit from a touchless, warm, and fully automated bathroom experience, the RS justifies every aspect of its positioning as TOTO’s entry point into the Neorest lineup.
The best bidets for home use guide is worth a read if you’re still weighing integrated toilets against high-end bidet seats.
Controls and Installation
The block-style remote is intuitive by smart toilet standards — the buttons are logically grouped and clearly labeled, with a wall-mount bracket included so it sits accessibly within arm’s reach without resting on the tank.
The learning curve is real but manageable — most users are comfortable with the essential controls within a couple of sessions and confident with the full feature set within a week.
Installation is more involved than adding a bidet seat to your current toilet.
You’re replacing the entire toilet, which means a plumber is strongly recommended for disconnecting the existing unit, rough-in verification, and final connection — this is not a typical DIY afternoon project.
That said, the RS ships with detailed installation manuals for both the top unit and bowl components, and the unit separates into manageable pieces for transport through a standard bathroom doorway.
The water supply can enter from either the floor or the wall at 4.5″ from center, which gives you flexibility if your existing plumbing comes from a non-standard position.
A GFCI outlet is required within reach — the power cord is 3.9 feet, so plan outlet placement accordingly before installation day.

Who Is the TOTO NEOREST RS Best For?
The RS is the right choice if you’re ready to commit to a full bathroom renovation or toilet replacement and want the most feature-complete smart toilet at the entry level of TOTO’s integrated Neorest lineup.
It’s particularly well-suited to multi-person households where the four-user preset system, touchless auto flush, and auto open/close lid deliver a genuinely hands-free, personalized experience for every family member.
Seniors and users with limited mobility benefit significantly from the Universal Height seat, the touchless controls, and the warm water bidet that eliminates the need for reaching, twisting, and wiping.
If you’ve been using a premium bidet seat like the TOTO K300 or Brondell Swash 1400 and want the next level of integration and automation, the RS is the natural step up.
And if you’re trying to decide between the RS and the step-up Neorest AS, the core question is whether the AS’s additional EWATER+ under-seat rinse and angled, contemporary design justify the price difference for your household — both models deliver the same core Neorest experience.
FAQ
What did the TOTO NEOREST RS replace?
The NEOREST RS replaced the discontinued TOTO Neorest RH.
The two key improvements over the RH are four user memory presets instead of two, and a redesigned block-style remote that includes a dedicated preset button and a more intuitive layout.
The design also received an update — the RS has a softer, more rounded organic shape compared to the more utilitarian profile of the original RH.
If you’re replacing an aging RH or evaluating the RS against memory of that model, the core hygiene technology is the same with these meaningful comfort and usability upgrades layered on top.
Does the TOTO NEOREST RS fit in a standard bathroom?
It can, but you need to verify your rough-in dimensions before ordering.
The RS measures 27-1/8″ L × 15-1/4″ W × 21-1/2″ H, which is larger than a standard residential toilet.
The standard 12″ rough-in (center of drain to finished back wall) applies, and the water supply must be positioned 4.5″ from center on the left side when facing the unit.
TOTO publishes a spec sheet and installation manual for the RS with detailed dimensional drawings — reviewing these before purchasing is strongly recommended, particularly for smaller bathrooms.
What’s the difference between the TOTO NEOREST RS and NEOREST AS?
Both are current-generation Neorest integrated smart toilets sharing the same core technology: auto open/close lid, auto flush, PREMIST, EWATER+, tankless water heating, and four-user presets.
The Neorest AS adds one key hygiene feature the RS lacks: an additional EWATER+ rinse beneath the seat (not just the wand and bowl), which provides an extra layer of sanitization.
The AS also uses a metal stick-style remote compared to the RS’s plastic block-style remote, and the AS has a more angular, contemporary design versus the RS’s softer curves.
The AS’s lid hinge is positioned farther back on the toilet, which gives you a larger usable seating area — a practical difference some users will notice.
If the under-seat EWATER+ rinse, larger seating area, and contemporary design aesthetic matter to you, the AS is worth the step up.
If the RS’s organic design suits your bathroom and the core Neorest experience is what you’re after, the RS delivers it fully.
Can I install the TOTO NEOREST RS myself?
Technically yes, but professional installation is strongly recommended.
Unlike adding a bidet seat to an existing toilet — which most people complete in 30 to 45 minutes — the Neorest RS involves removing and disposing of your current toilet, verifying rough-in alignment, and making both plumbing and electrical connections to a heavy, precision-engineered unit.
The RS ships in two components (top unit and bowl unit) with separate installation manuals for each.
A plumber with experience in one-piece toilet installations will handle the process efficiently and ensure the connections meet local code requirements — a worthwhile investment given the value of the unit.
Conclusion
The TOTO NEOREST RS is one of the most complete smart bathroom purchases you can make at its tier — a fully integrated touchless toilet and bidet that handles virtually every hygiene and comfort function automatically the moment you walk in.
PREMIST, CEFIONTECT, TORNADO FLUSH, EWATER+, instantaneous warm water, four-user presets, a 3-year warranty, and ADA-compliant Universal Height all come standard.
The trade-offs are real: you’re replacing your entire toilet, it ships freight to curbside only, the footprint is larger than a conventional unit, and Cotton White is your only color option.
But for buyers who want the cleanest, most automated, most hygienic bathroom experience available at the entry level of TOTO’s flagship Neorest lineup — the RS delivers it without compromise.
For more context on how the RS compares to simpler upgrades, see the best bidets for existing toilets guide and the bidet toilet seat comparison chart — both help you decide whether an integrated toilet or a premium bidet seat is the right path for your bathroom and budget.
