Is the TOTO Neorest NX1 Worth It?
Yes — for the right buyer, the Neorest NX1 is absolutely worth it.
This is not a bidet seat you add to an existing toilet.
It is a complete bathroom upgrade: a fully integrated smart toilet that handles everything automatically — from welcoming you with an open lid to flushing and closing on its way out.
If you are comparing this to a premium bidet seat like the TOTO Washlet S7 and wondering whether the jump to an integrated unit makes sense, the NX1 answers that question with a definitive yes — provided the budget is there.
Where the NX1 earns its price is in the totality of the experience.
Every single interaction is hands-free.
Every hygiene function runs automatically.
And the design itself commands attention in a way no bidet seat ever could.
For buyers who want a toilet that feels like it belongs in a five-star hotel — and are willing to invest accordingly — the NX1 delivers without compromise.
Design & Build Quality
The NX1’s silhouette is genuinely unlike anything else in the smart toilet category.
Its egg-like elliptical form — all smooth, continuous curves with no visible seams, buttons, or mechanical hardware — gives it the look of a sculptural art piece rather than a bathroom fixture.
TOTO describes it as inspired by Japanese handcrafted pottery, and you can see that influence clearly.
The vitreous china construction feels dense and premium, with a CEFIONTECT ion-barrier glaze that makes the surface extraordinarily smooth to the touch.
That glaze is functional as well as beautiful — waste simply does not stick to the bowl surface, which means far less scrubbing and fewer cleaning chemicals needed over time.
The stainless steel wireless remote is a standout accessory — slim, minimal, and wall-mounted, it matches the NX1’s aesthetic and puts every function at your fingertips without cluttering the toilet itself.
If you’ve been researching the best toilets with bidet built in, you’ll immediately recognize why the NX1’s design sets it apart from conventional bidet toilet combos.
At 31.5″ deep by 18.4″ wide by 23″ tall with a 17.3″ seat height, it fits a standard 12″ rough-in — but you should measure your bathroom clearance carefully before ordering, as the organic shape can feel larger in tighter spaces.
Cleaning Performance
The TORNADO FLUSH system uses dual 3-inch velocity release nozzles to generate a powerful cyclonic rinse that covers 100% of the bowl with every flush.
At just 1.0 GPF (or 0.8 GPF for lighter flushes), it is one of the most water-efficient flush systems available on any toilet in this class.
Combined with CEFIONTECT, the bowl genuinely stays cleaner between scrubs than any conventional toilet.
The EWATER+ system is where the NX1’s hygiene story really separates itself from the competition.
After every use, it automatically mists the bidet wand, the toilet bowl, and the underside of the seat with electrolyzed water — a gentle, chemical-free sanitizing agent that neutralizes bacteria without any effort on your part.
Even during idle periods, the NX1 triggers an automatic self-cleaning cycle after 8 hours of inactivity.
Pair this with the PREMIST function — which coats the bowl with a fine film of water before you sit down to prevent waste from adhering — and you have a toilet that is actively cleaning itself around the clock.
For anyone who has read our guide on the highest rated bidet toilets, it’s clear why the NX1 consistently appears at the top of those lists.
Comfort Features
The bidet wand delivers five wash modes: rear cleanse, soft rear cleanse, front feminine cleanse, oscillating, and pulsating.
Water temperature and pressure are both adjustable across five levels, with your preferred settings saveable in one of four user memory presets.
For multi-person households, this means every user can have their exact preference loaded and ready with a single tap on the remote.
The heated seat runs at up to five temperature levels.
One real-world note worth knowing: unlike some older Neorest models where the seat stayed continuously pre-heated, the NX1 operates in a standby mode at a lower base temperature and heats to your chosen setting after its body sensor detects you sitting.
The warm-up takes about 10 seconds — something most users adapt to quickly, but worth knowing going in.
The warm air dryer is adjustable and completes a hands-free session without any toilet paper needed.
The night light casts a soft blue glow into the bowl — subtle, easy on the eyes, and genuinely useful in the dark without needing to flip on overhead lights.

Controls & Installation
The NX1 ships with a sleek stainless steel block-style wireless remote designed to wall-mount cleanly beside the toilet.
It controls everything: spray position, pressure, water and seat temperature, dryer strength, deodorizer, flush, and lid operation.
The layout is intuitive, with well-labeled buttons that are easy to operate even for first-time users.
Installation follows a standard toilet replacement process — connecting the water supply line and a GFCI outlet.
However, because the NX1 ships via LTL freight and is significantly heavier than a standard toilet, professional installation is strongly recommended.
All Neorest models are designed for a 12″ rough-in, so if your bathroom is set up for that (which most American bathrooms are), there should be no plumbing surprises.
You will need a GFCI outlet within reach — if you don’t already have one near the toilet, budget for an electrician.
If you’re deciding between adding a top-tier bidet seat versus going fully integrated, our guide to the bidet toilet vs bidet seat debate breaks down the real differences in cost, installation, and experience.
Who Is the TOTO Neorest NX1 Best For?
The NX1 is for buyers who are ready to replace their toilet entirely and want the most design-forward, feature-complete integrated smart toilet available.
It is the right fit if you are renovating a bathroom from scratch, building a new home, or upgrading a master bathroom where aesthetics and luxury performance are equally important.
It is particularly well-suited to multi-person households who will benefit from the four user memory presets — no one has to reset their preferences between uses.
If you are exploring the broader world of the best bidets for home use, the NX1 sits firmly at the top of that hierarchy.
It is less ideal if you want to keep your existing toilet, are on a tighter budget, or need something a plumber can swap out in an afternoon without freight delivery.
For that scenario, a seat like the TOTO Washlet S5 delivers incredible performance at a fraction of the NX1’s footprint and cost.
But if you want the very best — and your bathroom can accommodate it — the Neorest NX1 is in a category by itself.
FAQ
Is the TOTO Neorest NX1 discontinued?
No. The NX1 is TOTO’s current flagship elliptical smart toilet and is actively sold and supported.
It sits below the NX2 in TOTO’s lineup — the only difference between the two is that the NX2 adds the Actilight UV-powered bowl sanitization system.
If you are exploring how it compares with other Neorest models, our guide to the highest rated bidet toilets covers the full lineup.
What is the difference between the NX1 and the NX2?
The NX2 adds TOTO’s Actilight system, which uses UV light to activate a zirconium coating inside the bowl, providing an additional layer of self-sanitization beyond EWATER+ and PREMIST.
In practice, both are exceptional at keeping the bowl clean — the NX2 simply adds one more layer of autonomous hygiene technology for those who want it.
The NX1 is more widely available and offered at a lower price point than the NX2.
Does the TOTO Neorest NX1 work with a round toilet rough-in?
The NX1 is designed exclusively for a 12″ rough-in elongated floor mount installation.
It is not compatible with unusual rough-in sizes (10″ or 14″) without modification, and it replaces your existing toilet entirely rather than fitting onto an existing bowl.
Always confirm your rough-in measurement before ordering.
How does the NX1 compare to a top-tier bidet seat like the TOTO Washlet S7?
The TOTO Washlet S7 is the best bidet seat TOTO makes — and it delivers an outstanding experience on any compatible existing toilet.
The NX1 goes further: it replaces your toilet entirely, adds fully autonomous bowl cleaning, auto-lid operation, auto-flush, and the iconic elliptical one-piece form that no seat can replicate.
If budget and toilet replacement are not obstacles, the NX1 wins on every dimension.
If you want to keep your current toilet and still get excellent bidet performance, the S7 is the smarter practical choice.
Conclusion
The TOTO Neorest NX1 is one of the most impressive bathroom fixtures you can buy — a fully autonomous, gorgeously designed smart toilet that handles every aspect of hygiene without you lifting a finger.
Its EWATER+ system, PREMIST function, CEFIONTECT glaze, and TORNADO FLUSH technology combine to create a toilet that is actively cleaning itself around the clock.
The elliptical design is genuinely stunning, the stainless steel remote is intuitive, and the four user presets make it a practical fit for the whole household.
The trade-offs are real: the heated seat takes about 10 seconds to reach full temperature, it ships freight, and professional installation is a practical necessity.
But for the buyer who is ready to invest in the absolute best, the NX1 rewards that decision every single day.
