Design and Aesthetics: Which One Looks Better?
This is genuinely where the two toilets diverge the most — and it comes down to personal style.
The Neorest RH has a rounded, pebble-like form.
Every curve is soft and organic, and the overall profile has an almost sculptural quality that makes it look like it was carved rather than manufactured.
It was clearly inspired by the Neorest 500H, and buyers who loved that model will feel right at home with the RH.
The Neorest RS takes a different approach.
Its curves are equally smooth, but the silhouette is more structured — TOTO describes it as a “serene” form designed to harmonize with its surroundings rather than stand out.
In most bathrooms, the RS will read as more contemporary and architectural, while the RH feels warmer and more spa-like.
Winner: Tie — it’s entirely a matter of personal aesthetic.
Neither toilet is objectively more beautiful than the other.
If you want a rounded, organic feel, the RH wins.
If you prefer clean, structured curves that recede into the bathroom design, the RS is your pick.
For a broader look at how integrated smart toilets compare to bidet seat upgrades in terms of bathroom aesthetics, our bidet toilet vs bidet seat guide is worth a read.
Hygiene Technology: Which One Cleans Better?
Both toilets share the same foundation: CEFIONTECT ceramic glaze, PREMIST bowl pre-misting, and EWATER+ electrolyzed water auto-cleaning.
On the surface, that sounds like a tie — but the RS goes further in two meaningful ways.
First, the RS’s EWATER+ system also mists the under-seat area after every use, something the RH does not do.
That’s a zone that accumulates moisture and bacteria over time, and having it automatically treated with electrolyzed water after every flush is a genuine hygiene upgrade.
Second, the RS uses CLEAN RESIN for both the wand and seat surface.
This proprietary material is engineered to be more resistant to bacterial adhesion than standard plastics, making both surfaces measurably easier to keep hygienic between uses.
The RH has neither of these additions — it was built before TOTO developed these refinements.
Winner: TOTO Neorest RS.
The under-seat EWATER+ coverage and CLEAN RESIN technology give the RS a meaningful hygiene advantage that matters in daily real-world use.
If bowl hygiene is important to you — and it should be — our comparison of TOTO’s WASHLET S5 vs S7 covers how EWATER+ works in practice at the seat level too.
User Presets and Multi-User Households
The memory preset gap between these two toilets is one of the clearest practical differences.
The Neorest RH supports 2 user memory settings — enough for a couple sharing a bathroom, where each person saves their preferred wand position, water temperature, pressure, and seat warmth.
The Neorest RS doubles that to 4 user memory settings.
For families, households with live-in relatives, or anyone who has guests regularly, that extra flexibility removes the need to manually reset preferences every time someone different uses the toilet.
It’s a seemingly small upgrade that becomes genuinely important in day-to-day use.
Winner: TOTO Neorest RS.
Four presets is strictly better than two, and for a toilet at this price point, you’ll want everyone in the household to have their settings saved and ready.
For comparison on how preset counts matter across TOTO’s seat lineup, our bidet toilet seat comparison chart shows how this plays out across the brand’s full range.
Availability and Long-Term Ownership
This is where the comparison becomes straightforward.
The TOTO Neorest RH is officially discontinued.
Remaining units are available through existing retailer stock, but once that inventory clears, replacement parts and warranty support become increasingly uncertain.
For a toilet at this price point — a unit you expect to use for 15 to 20 years — that’s a real consideration.
The RS, by contrast, is TOTO’s current production model in this category.
You get a fresh warranty, full parts availability, and the assurance that TOTO’s support infrastructure is behind it for the long term.
Winner: TOTO Neorest RS — and it’s not close.
Buying a discontinued luxury toilet is a risk that’s hard to justify when the current replacement model is better in nearly every measurable way.

Verdict — Which One Should You Buy?
The answer here is clearer than most head-to-head comparisons allow.
Buy the TOTO Neorest RS if… you’re making a fresh purchase decision and want the most advanced, most hygienically complete integrated smart toilet TOTO currently makes at this tier.
The RS wins on hygiene technology (EWATER+ under-seat, CLEAN RESIN), user presets (4 vs 2), and long-term availability.
It’s the smarter investment — full stop.
Buy the TOTO Neorest RH if… you specifically love its rounded organic aesthetic and have found remaining new stock at a significantly lower price than the RS, and you’re comfortable with the discontinued status.
The RH is still a brilliant toilet with the full Neorest feature set — it’s just the older generation, and the value case depends almost entirely on the price delta you can capture on remaining inventory.
For buyers still weighing whether to go with an integrated unit or a high-end seat on their existing toilet, our best bidets for existing toilets guide is a good place to compare what’s possible at a lower price point.
FAQ
Is the TOTO Neorest RH discontinued?
Yes, the TOTO Neorest RH (MS988CUMFG) has been officially discontinued by TOTO.
Remaining units are still available through some retailers while stock lasts, but TOTO no longer actively produces it.
The TOTO Neorest RS (MS8341CUMFG) is the recommended current-generation replacement, offering all the same core features plus meaningful upgrades including extended EWATER+ coverage and 4 user memory presets instead of 2.
What is the difference between the Neorest RS and Neorest RH?
Both share the same foundational TOTO technology: TORNADO FLUSH, CEFIONTECT glaze, PREMIST, EWATER+, auto open/close lid, auto flush, heated seat, warm air dryer, deodorizer, and wireless remote.
The RS adds three upgrades the RH does not have: EWATER+ misting of the under-seat area, CLEAN RESIN wand and seat construction for superior hygiene, and 4 user memory presets vs 2.
The main reason to choose the RH over the RS is design preference — some buyers prefer its rounder, pebble-like form.
Are the Neorest RS and RH the same size?
Nearly, but not exactly.
Both are 27-1/8″ deep and within a fraction of an inch in width (15-1/4″ for the RS vs 15-3/16″ for the RH).
The RS is very slightly taller at 21-1/2″ vs the RH’s 21-1/16″.
In practice, the footprint difference is negligible, and both fit a standard 12″ rough-in.

How does the TOTO Neorest RS compare to the Neorest AS?
The Neorest AS is positioned one tier above the RS and adds 4 user presets (same as RS), Actilight UV bowl sanitizing (not on the RS), and a slightly different aesthetic profile.
For buyers who want the absolute top of the Neorest lineup with UV cleaning, the AS is worth the additional investment.
For most buyers, the RS delivers the same core Neorest experience at a meaningfully lower cost.

Conclusion
The TOTO Neorest RS vs RH debate is one that resolves clearly once you weigh what actually matters in a luxury smart toilet purchase.
The RH is a beautiful toilet with a devoted fanbase — and if remaining stock is available at a compelling discount, it remains a worthwhile unit.
But in virtually every objective category — hygiene technology, user flexibility, long-term support, and parts availability — the RS wins.
It’s the better product by design, and it’s the one TOTO currently stands behind.
