1. TOTO Neorest RS Dual Flush Integrated Bidet Toilet
The TOTO Neorest RS is the entry point to TOTO’s Neorest integrated toilet lineup — and “entry point” is doing a lot of heavy lifting here.
This is still a fully hands-free, self-cleaning, heated, auto-flushing smart toilet with a remote control and four user memory presets.
Its organic, soft-curved silhouette gives it a serene, spa-like look that blends into almost any bathroom interior.
Features
- Compact footprint: 27-1/8″ L x 15-1/4″ W x 21-1/2″ H — one of the smallest Neorest models available
- 1G Tornado Flush dual-flush system (1.0 / 0.8 GPF) with CEFIONTECT glaze
- EWATER+ automatically mists and sanitizes the wand and bowl after every use
- PREMIST pre-wets the bowl before each use, making waste 80% less likely to stick
- Instantaneous warm water heater — unlimited warm water, never runs cold
- Five wash modes: rear cleanse, soft rear cleanse, front cleanse, oscillating, pulsating
- Heated seat with five temperature settings and automatic lid open/close
- Four user memory presets, warm air dryer, air deodorizer, and night light
- ADA compliant at Universal Height (17-11/16″ floor to seat)
- Three-year limited residential warranty
Pros
- Most compact Neorest available — ideal for smaller bathroom footprints
- Elegant organic shape suits a wide range of interior design styles
- EWATER+ + PREMIST combination keeps the bowl exceptionally clean day-to-day
- Four user presets make it perfect for multi-person households
- Significantly lower price point than the NX2 while still being a luxury integrated toilet
Cons
- No ACTILIGHT UV self-cleaning — you will need occasional manual bowl cleaning
- Narrower bowl width compared to the NX2’s elliptical form
If you want a world-class integrated bidet toilet with TOTO’s full Clean Synergy suite — PREMIST, EWATER+, CEFIONTECT, and Tornado Flush — but don’t need the autonomous UV self-cleaning that ACTILIGHT provides, the RS is an outstanding choice.
It’s the smarter value buy for most households stepping up to the Neorest level for the first time.

2. TOTO Neorest NX2 Dual Flush Integrated Bidet Toilet
The TOTO Neorest NX2 is TOTO’s most advanced residential toilet — the absolute flagship of the entire Neorest lineup.
Its dramatic elliptical silhouette, inspired by the organic beauty of pebbles shaped by water over time, is immediately recognizable as something different.
But the design is not even its most impressive feature — that title belongs to ACTILIGHT, TOTO’s exclusive UV photocatalytic self-cleaning system built into the lid.
Features
- Larger sculptural footprint: ~31-1/2″ L x 18-7/16″ W x 23″ H — a true bathroom centerpiece
- ACTILIGHT: UV light in the lid activates a zirconium photocatalytic glaze that breaks down organic matter at the molecular level — no chemicals, no scrubbing
- Self-cleaning cycle activates after 8 hours of inactivity, keeping the bowl immaculate between uses
- EWATER+ sanitizes the wand, bowl interior, and under-seat area after every use
- PREMIST pre-wets the bowl before each use for superior waste elimination
- CLEAN RESIN wand and seat material keeps surfaces more hygienic with less effort
- 1G Tornado Flush dual-flush system (1.0 / 0.8 GPF) with CEFIONTECT glaze
- Instantaneous water heater, five wash modes, four user presets, heated seat, air dryer, night light
- ADA compliant at Universal Height (17-5/16″ floor to seat)
- Three-year limited residential warranty
Pros
- ACTILIGHT is the most advanced self-cleaning toilet technology available to residential buyers — nothing else comes close
- Bowl stays cleaner autonomously, with no need for manual scrubbing between deep cleans
- Sculptural elliptical design is a genuine design statement — the Neorest NX2 looks like modern art in your bathroom
- CLEAN RESIN adds another layer of hygiene to the wand and seat surfaces
- The most complete Clean Synergy experience TOTO has ever built into a single toilet
Cons
- Substantially higher price than the RS — the gap is significant
- Larger footprint requires more bathroom floor space
- Available only in Cotton White — no color alternatives
If you are building or renovating a luxury bathroom and you want the best available technology in a toilet — one that genuinely cleans itself between uses without any effort on your part — the NX2 is the only toilet in the world that delivers at this level.
It is one of the most impressive bathroom fixtures available anywhere.

Design and Footprint: Compact Elegance vs. Sculptural Statement
The Neorest RS has a soft, gently curving silhouette that blends quietly into a bathroom.
At 27-1/8″ long and 15-1/4″ wide, it’s notably more compact than the NX2 — making it the right choice if your bathroom is working with limited floor space or you prefer a toilet that doesn’t dominate the room.
The Neorest NX2 takes the opposite approach.
Its elliptical, pebble-like form is a deliberate design statement — at 31-1/2″ long and 18-7/16″ wide, it commands attention and looks like a premium fixture the moment you walk into the room.
If you’re designing a bathroom from scratch around a showpiece toilet, the NX2 wins this category decisively.
If you’re working with an existing bathroom and fitting a new toilet into a defined space, the RS is the more practical choice and no less elegant in its own right.
For more on color and finish options, see our guide on TOTO Cotton White vs Colonial White — worth reading before you finalize your order.
Winner: TOTO Neorest NX2 for maximum design impact; TOTO Neorest RS for smaller spaces.
Self-Cleaning Technology: Where the NX2 Pulls Away
Both toilets share TOTO’s core Clean Synergy suite: EWATER+, PREMIST, and CEFIONTECT glaze.
EWATER+ uses electrolyzed water to mist and sanitize the wand and bowl interior after every use — no chemicals required.
PREMIST pre-wets the bowl before you sit, making waste dramatically less likely to stick and significantly reducing how often you need to scrub.
These two technologies together already make both toilets far easier to maintain than any conventional toilet.
But the NX2 goes a step further that the RS simply cannot match: ACTILIGHT.
ACTILIGHT combines a UV light built into the lid with a special zirconium photocatalytic bowl coating.
When UV light hits the coating, it breaks down organic matter at a molecular level — continuously, passively, without any chemicals, without any intervention from you.
The NX2 even runs an automatic self-cleaning cycle after 8 hours of inactivity, so the bowl is always at its cleanest before you sit down.
There is no other residential toilet in the world that offers this level of autonomous self-cleaning.
If minimizing manual cleaning effort is a priority — or if you’re looking for the best solution for elderly family members who find cleaning difficult — this is a decisive advantage.
Our guide to the best bidets for seniors covers why hands-free, low-maintenance features like this matter so much for older users.
Winner: TOTO Neorest NX2 — ACTILIGHT is a genuine technological leap.
Wash Performance: A Tie at the Highest Level
When it comes to the actual bidet washing experience, both models are equally excellent.
You get five wash modes on both: rear cleanse, soft rear cleanse, front cleanse, oscillating, and pulsating.
Both use an instantaneous water heater for unlimited warm water — no tank to run dry mid-wash.
Both offer four user memory presets so every member of your household can save their exact temperature, pressure, and position preferences.
The NX2 also features CLEAN RESIN on the wand and seat surface — a material that repels residue more effectively than standard plastic, adding one more layer of passive hygiene.
But in terms of the wash itself — spray coverage, water pressure, wash modes, and temperature control — you will not notice a difference between the RS and the NX2 during normal use.
Both deliver TOTO’s top-tier bidet performance.
If you’re coming from a bidet seat and wondering what you’d gain from going fully integrated, our bidet toilet vs bidet seat guide breaks that down in detail.
Winner: Tie — both deliver TOTO’s best-in-class wash experience.
Flushing Performance: Identical Engineering
Both the RS and the NX2 use TOTO’s 1G Tornado Flush system — a hole-free rim design with dual-nozzle jets that generate a powerful cyclonic rinsing action covering every part of the bowl.
Both offer a dual-flush of 1.0 GPF (for heavier jobs) and 0.8 GPF (for lighter ones), both are WaterSense certified, and both include an automatic flush that activates when you rise from the seat — with a manual override for power outages.
CEFIONTECT ion-barrier glaze is on both models, reducing how much waste sticks to ceramic surfaces and making the flush more effective with less water.
If you’re also comparing performance across other TOTO integrated toilet models, our best toilets with bidet guide covers the full landscape at different price points.
Winner: Tie — identical flushing technology and efficiency.
Value: What You’re Actually Paying For
The Neorest RS is significantly less expensive than the NX2 — and the gap is substantial.
For the RS, you’re getting every core TOTO Neorest feature: EWATER+, PREMIST, CEFIONTECT, Tornado Flush, unlimited warm water, four user presets, auto flush, auto lid, heated seat, air dryer, night light, and a three-year warranty.
The NX2 adds ACTILIGHT UV self-cleaning, CLEAN RESIN surfaces, and its iconic sculptural design — and charges a premium for them.
Whether that premium is worth it depends entirely on how much passive bowl cleanliness matters to you.
If you’re someone who dislikes cleaning the toilet and wants technology to handle it for you as completely as possible, the NX2 makes a compelling case.
If you want TOTO’s best-in-class bidet experience at the most accessible Neorest price point, the RS is the answer — and it is still one of the finest toilets available anywhere.

Winner: TOTO Neorest RS for value; TOTO Neorest NX2 if ACTILIGHT justifies the premium for you.

Frequently Asked Questions
Is the TOTO Neorest 550e the same as the NX2?
The TOTO Neorest 550e is discontinued.
The NX2 is the current model that carries forward the 550e’s legacy at the premium end of the Neorest lineup, and it adds significant upgrades including ACTILIGHT UV self-cleaning, an updated Tornado Flush system, CLEAN RESIN surfaces, and a redesigned elliptical bowl for improved performance and cleanliness.
If you were considering the 550e, the NX2 is the recommended current-generation replacement.
What is ACTILIGHT and why does only the NX2 have it?
ACTILIGHT is a proprietary TOTO self-cleaning system that combines a UV light built into the toilet lid with a special zirconium photocatalytic glaze applied to the bowl surface.
When the UV light activates, it triggers a reaction that breaks down organic matter at the molecular level — continuously sanitizing the bowl without chemicals or physical scrubbing.
It is exclusive to the NX2 within TOTO’s current Neorest floor-mounted lineup because it requires the premium zirconium bowl coating in addition to the UV light hardware, which adds significant manufacturing cost.
The RS uses EWATER+ and PREMIST for daily bowl hygiene, which are excellent systems — but ACTILIGHT represents a fundamentally different and more autonomous level of self-cleaning.
Can I install the Neorest RS or NX2 myself?
Both toilets require a standard 12″ rough-in floor drain and a nearby GFCI electrical outlet.
While experienced DIYers can handle the water supply connection, most homeowners choose to use a licensed plumber for the initial installation of a Neorest, given the complexity of the unit and the investment involved.
Neither toilet requires in-wall work — both are floor-mounted one-piece units — but the remote wall-mount bracket installation and electrical requirements are best handled by a professional.
How does the Neorest RS compare to the Neorest AS and LS?
The RS is the most compact and most accessible Neorest model, designed with organic soft curves.
The AS shares most of the same features as the RS but has a more angular, modern linear design and a slightly different silhouette — ideal for minimalist or contemporary bathrooms.
The LS is the largest and most feature-complete non-ACTILIGHT Neorest, designed for ADA accessibility with an ultra-linear form.
None of the RS, AS, or LS models include ACTILIGHT — that technology remains exclusive to the NX2 at the top of the floor-mounted Neorest range.

Conclusion
Both the TOTO Neorest RS and the TOTO Neorest NX2 are exceptional integrated smart toilets — they represent the best that bathroom technology has to offer.
The RS is the smarter value choice: a compact, beautifully designed luxury toilet that delivers TOTO’s full Clean Synergy bidet experience at a significantly lower price than the NX2.
The NX2 is the right choice if you want the single best toilet TOTO has ever made — one with ACTILIGHT UV self-cleaning that puts it in a category of its own.
Most buyers who are making the leap to a fully integrated Neorest for the first time will find the RS meets every need they have.
Those who are building a luxury bathroom around a statement fixture and want the most autonomous, low-effort toilet experience imaginable should go straight to the NX2.
Whichever you choose, you are investing in a toilet that will transform your bathroom routine — and if you want to compare more premium options side by side, our best toilets with bidet guide is the perfect next read.
