Is the TOTO Nexus Worth It?
Yes — and quite comfortably so.
The TOTO Nexus isn’t just a pretty toilet.
It’s a precision-engineered, one-piece skirted unit that solves the two biggest problems homeowners have with standard toilets: cleaning difficulty and flush reliability.
If you’re renovating a bathroom and want a toilet that performs at a high level, looks genuinely modern, and is ready to pair with a premium bidet seat down the line — the Nexus delivers on all three counts.
It’s not the cheapest one-piece toilet on the market, but for what it offers in flush technology, surface protection, and WASHLET+ integration, the value proposition is solid.
For context on where it sits in TOTO’s toilet lineup, our TOTO Drake vs Nexus comparison breaks down exactly how these two popular models stack up against each other.
Design & Build Quality
The Nexus is unmistakably modern.
Its one-piece construction fuses the tank and bowl into a single vitreous china unit — no gap, no seam, no place for grime to hide between the tank base and the floor.
The fully skirted design takes this further by concealing the entire trapway behind a smooth, curved ceramic surface that sweeps cleanly down to the floor.
You won’t find yourself reaching behind the bowl with a bottle of cleaner and a brush trying to get into all the nooks and crannies that exposed trapway designs create.
A wipe-down is all it takes on the exterior.
The high-profile silhouette — 27″ tall — gives the Nexus a presence that feels intentional rather than bulky.
At 17-1/2″ wide and 28-5/8″ deep, it fits comfortably in most standard bathrooms without crowding the space.
CEFIONTECT glaze is applied across all interior ceramic surfaces — and it makes a real difference.
This ion-barrier coating creates an extraordinarily smooth surface that actively resists waste, mold, and mineral deposits from bonding to the porcelain.
Paired with the Tornado Flush, it means the bowl stays noticeably cleaner between cleanings than a standard glazed toilet bowl would.
If you’re deciding between color options, our TOTO Colonial White vs Cotton White guide can help you pick the right finish for your bathroom.
Flushing Performance
The TORNADO FLUSH system is the engineering heart of the Nexus — and it justifies TOTO’s reputation for powerful, efficient flushing.
Instead of a traditional rim with flush holes that collect mineral buildup and deliver uneven water coverage, the Nexus uses a hole-free rim with two precisely positioned nozzles.
These dual nozzles inject water at high velocity in opposing angles, creating a powerful centrifugal vortex that scrubs the entire bowl surface — from rim to trap — in a single, circular motion.
The result is a thorough, quiet, one-flush performance at just 1.28 gallons per flush.
For reference, older toilets commonly use 1.6 GPF or more — the Nexus delivers a visibly stronger result with 20% less water.
This earns it EPA WaterSense certification, CALGreen compliance, and compliance with California’s water efficiency standards.
The glazed trapway at 2-1/8″ diameter is also generous enough to handle demanding use without clogging concerns.

Comfort Features
The Nexus ships with TOTO’s SS124 SoftClose seat already included — a detail that many competing toilets in this price range omit.
The SoftClose mechanism uses hydraulic hinges to prevent the lid from slamming shut, which extends seat life and eliminates that jarring noise that echoes at 2 a.m.
Universal Height is one of the most underrated features of this toilet.
The bowl rim sits at 16-1/8″ from the floor — about an inch taller than a standard toilet — which makes it significantly more comfortable for adults to sit and stand without straining.
It’s also ADA compliant when the trip lever is installed on the approach side, making it appropriate for households with seniors or anyone with limited mobility.
If accessibility is a priority, our guide to the best bidets for seniors covers companion seat options that pair well with the Nexus.
The elongated bowl shape adds roughly two additional inches of seating surface compared to a round bowl, which most adults find noticeably more comfortable for extended use.
WASHLET+ Integration
This is where the TOTO Nexus separates itself from the competition in a meaningful way.
The Nexus is designed specifically as a WASHLET+ T40 compatible toilet — meaning it has a discreet channel routed through the bowl surface to conceal the power cord and water supply line of a compatible TOTO bidet seat.
When you pair it with a TOTO S-series WASHLET like the S5 or S7, the seat integrates so seamlessly that the result looks indistinguishable from a fully integrated smart toilet.
No exposed cords dangling from the seat.
No supply line running visibly along the floor.
Just a clean, continuous toilet-and-seat profile that rivals the look of units costing several times more.
The Nexus is also compatible with auto-flush functionality when paired with an auto-flush-ready WASHLET — a detail that brings a fully touchless bathroom experience within reach without replacing the entire toilet.
If you’re considering which WASHLET seat to pair with the Nexus, our TOTO C5 vs S5 comparison and our C5 vs S7 breakdown are both worth reading to understand the current TOTO bidet seat lineup.

Installation
Installing a one-piece toilet is more involved than a standard two-piece, primarily because of weight.
The Nexus ships at around 117 lbs in its box — plan for two people to handle the lift and positioning safely.
Beyond the weight, installation follows a standard process: set the wax ring, position the toilet over the floor flange, secure with mounting bolts, and connect the supply line.
The standard rough-in is 12″ — the most common residential measurement by far.
If your bathroom has a 14″ rough-in, TOTO sells an adapter (TSU10W.14) separately.
Note that additional consumables — wax ring, floor bolts, and supply line — are not included and need to be purchased separately.
The chrome trip lever is left-hand by default, but brushed nickel and polished nickel lever options are sold separately if you want to match your bathroom hardware exactly.
Once installed, the skirted base’s smooth exterior means no awkward gap between the toilet base and the floor to caulk around exposed hardware.
Who Is the TOTO Nexus Best For?
The Nexus is the right choice for bathroom remodelers who want a toilet that looks premium, cleans itself more effectively between scrubs, and gives them a clear upgrade path to a bidet seat without visible cords or plumbing compromises.
It’s ideal if you’re planning to pair it with a heated bidet seat or a TOTO WASHLET now or in the future — the WASHLET+ design makes that upgrade dramatically cleaner-looking than on any non-WASHLET+ toilet.
It’s also a strong pick for multi-generational households where Universal Height and ADA compliance matter.
It may not be the right fit if you’re on a strict budget, need a round bowl, or want a toilet with a longer warranty — in those cases, exploring the broader highest rated bidet toilet options might help you find a better match.

FAQ
Is the TOTO Nexus the same as the Nexus II?
TOTO’s website currently lists the Nexus under the “Nexus II” name for some product pages, but the model number MS642124CEFG remains the same unit.
The Nexus II designation appears to reflect a branding refresh rather than a hardware change — specs, features, and ASIN are unchanged from what has been sold as the original Nexus.
Does the TOTO Nexus work with round toilets?
No — the Nexus is available only with an elongated bowl.
If you need a round bowl configuration, the Nexus is not the right model for your bathroom.
TOTO offers other skirted designs in round versions, so it’s worth checking the full lineup if bowl shape is a constraint for you.
What’s the difference between the Nexus and TOTO’s Aimes toilet?
Both are one-piece skirted WASHLET+ compatible toilets with CEFIONTECT and Tornado Flush.
The Aimes has a slightly different exterior silhouette — a more architectural, angular profile — while the Nexus has a softer, more rounded high-profile look.
Performance is essentially equivalent; the choice comes down to aesthetic preference and compatibility with your bathroom’s design direction.
Our TOTO Aimes WASHLET+ S7A review gives you a detailed look at how the Aimes performs as a full toilet-plus-bidet system if you’re weighing both options.
Which WASHLET seat should I pair with the TOTO Nexus?
For T40 seamless WASHLET+ cord-concealment, the TOTO S5 is the best-value choice — unlimited warm water, PREMIST, EWATER+, four user presets, and Wirecutter’s top bidet seat pick.
If you want bowl EWATER+ and a slimmer 4.1″ profile, step up to the S7.
For auto open/close lid and proximity sensor, the S7A is the top non-Neorest option.
All three use the T40 system and integrate seamlessly with the Nexus.
Conclusion
The TOTO Nexus is a genuinely impressive one-piece toilet that earns its price through superior flushing engineering, smart surface protection, and a WASHLET+ integration system that no standard toilet can match.
The Tornado Flush is as reliable as it looks on paper — one flush, every time, with 1.28 GPF.
CEFIONTECT glaze actively reduces how often you need to scrub the bowl.
The fully skirted exterior makes cleaning the outside of your toilet a 20-second wipe instead of a 10-minute ordeal.
The one honest trade-off is the one-year warranty, which feels conservative for a premium-priced toilet — but TOTO’s engineering quality means most owners will never need to use it.
