1. TOTO Aimes One-Piece Elongated Toilet MS626234CEFG#01
The TOTO Aimes is a bold, high-profile one-piece toilet that makes an immediate visual statement in any bathroom.
Its fully skirted design conceals the trapway entirely, eliminating the hard-to-clean gaps you deal with on standard toilets.
If you’re planning to pair it with a WASHLET+ bidet seat, the Aimes is factory-designed for that exact integration — the T40-compatible channel hides the supply line and power cord for a truly seamless look.
Features
- One-piece elongated skirted design with a bold, high-profile silhouette
- Tornado Flush system (1.28 GPF) with dual-nozzle centrifugal action and a hole-free rim
- CeFiONtect ceramic glaze prevents waste from adhering to the bowl surface
- Universal Height for comfortable seating across a wide range of users
- WASHLET+ T40 ready for seamless bidet seat integration
- SoftClose slim seat included
- 12″ rough-in with optional adapters for 10″ or 14″
- ADA compliant and EPA WaterSense certified
Pros
- Exceptional design flexibility — one of the few TOTO toilets adaptable to all three rough-in sizes
- The high-profile silhouette gives it more visual weight and presence than the Nexus
- Tornado Flush keeps the bowl clean with minimal effort
- Great for bathrooms where you want a statement piece, not just a toilet
Cons
- Slightly taller profile may not suit every bathroom aesthetic
- The bolder design can look too heavy in smaller bathrooms
The Aimes is the toilet you choose when you want form and function in equal measure.
If your bathroom has an existing 10″ rough-in or you’re planning a WASHLET+ upgrade, this is the more flexible pick — and if you’re exploring all your toilet bidet combo options, the Aimes deserves a top spot on your list.

2. TOTO Nexus One-Piece Elongated Toilet MS642234CEFG#01
The TOTO Nexus takes a more restrained approach — where the Aimes is bold, the Nexus is quietly refined.
Its skirted design is described as “360 fully skirted,” and its lower profile gives it a sleeker, more contemporary appearance that feels at home in minimalist or transitional bathrooms.
The Nexus shares the same core TOTO DNA as the Aimes — Tornado Flush, CeFiONtect, WASHLET+ compatibility — but packages it in a slightly lower, more understated silhouette that many users find easier to live with day to day.
Features
- One-piece elongated 360 fully skirted design with a sleek, low-profile look
- Tornado Flush system (1.28 GPF) with dual-nozzle centrifugal bowl rinse
- CeFiONtect glaze for a cleaner bowl between scrubs
- Universal Height and ADA compliant
- WASHLET+ T40 compatible with Auto Flush ready capability
- SoftClose slim seat included
- 12″ rough-in, adaptable to 14″
- EPA WaterSense and CALGreen certified
Pros
- Cleaner, more streamlined silhouette that suits modern and minimalist bathrooms
- The flat tank lid is a practical bonus — you can actually set things on it
- Auto Flush compatibility is built in, unlike the Aimes
- 360 fully skirted design is arguably even easier to clean than the Aimes
Cons
- Only adapts to 14″ rough-in, not 10″ — less flexible than the Aimes
- Some users report the installation is slightly more involved due to the skirted design
The Nexus earns its place as one of the best-looking toilets in TOTO’s lineup, and it pairs beautifully with any WASHLET+ seat — if you want to explore what that upgrade looks like, our bidet seat comparison chart is a great place to start.

Head-to-Head: TOTO Aimes vs Nexus
Design and Aesthetics
The Aimes carries a high-profile, commanding look — it’s taller and more visually assertive.
The Nexus, at an inch shorter overall, sits lower and reads as more refined and contemporary.
If you’re designing a bathroom around a specific style, the Nexus tends to fit more universally, while the Aimes makes a stronger visual statement.
Winner: Nexus — for most modern bathrooms, its restrained silhouette ages better.
Rough-In Flexibility
This is the clearest practical difference between the two toilets.
The Aimes adapts to 10″, 12″, or 14″ rough-in configurations using optional TOTO adapters.
The Nexus only adapts to 12″ or 14″ — if your bathroom has a 10″ rough-in, the Aimes is your only option between these two.
Winner: Aimes — broader rough-in flexibility is a real advantage in older homes.
Flushing Performance
Both toilets use TOTO’s Tornado Flush with a 1.28 GPF single flush, a hole-free rim, and dual nozzles that create centrifugal cleaning action.
Both also feature CeFiONtect glaze, which means waste is far less likely to stick to the bowl in the first place.
In real-world use, performance is essentially identical between the two — this is a draw.
Winner: Tie — you get the same excellent flushing technology either way.
WASHLET+ and Smart Toilet Compatibility
Both toilets are T40 WASHLET+ ready, meaning they’re pre-engineered to conceal the bidet seat’s supply line and power cord.
The key difference: the Nexus has built-in Auto Flush compatibility, while the Aimes does not.
If you’re planning to add a high-end WASHLET+ seat like the S7A and want a fully automated, hands-free experience, the Nexus gives you that door without extra workarounds.
You can explore the full range of WASHLET+ compatible seats on our best bidets for home use guide or review the best heated bidet seats to understand what features pair best with either toilet.
Winner: Nexus — Auto Flush compatibility gives it a clear edge for smart bathroom setups.
Ease of Cleaning
Both have fully skirted designs that eliminate the exterior trapway nooks.
The Nexus is marketed specifically as a “360 fully skirted” design, which means there’s even less surface area to reach around.
The Aimes’ higher profile also means slightly more exterior surface overall.
Winner: Nexus — by a narrow margin, its lower and more fully enclosed design is slightly easier to wipe down.
Verdict: Which One Should You Buy?
Both toilets are excellent, and choosing between them comes down to your specific bathroom and how you plan to use the toilet long term.
Buy the TOTO Aimes if…
- Your bathroom has a 10″ rough-in — the Nexus simply won’t adapt to it
- You want a bolder, more high-profile toilet that becomes a focal point of the room
- You’re not planning to add Auto Flush and just want a reliable, feature-rich TOTO one-piece
- You’re pairing it with a standalone WASHLET seat and want the widest compatibility options
Buy the TOTO Nexus if…
- You want the cleanest, most streamlined look with a lower profile that fits any modern bathroom
- You’re planning a fully automated setup with Auto Flush
- Your rough-in is 12″ or 14″
- You appreciate the flat tank lid as a practical surface — it’s a small thing that becomes surprisingly useful
For most buyers in a standard 12″ rough-in bathroom who want a future-proof smart toilet setup, the TOTO Nexus edges ahead.
But if you’re working with a 10″ rough-in or simply love the look of the Aimes’ more dramatic silhouette, don’t second-guess yourself — the TOTO Aimes is every bit as capable.
FAQ
Are the TOTO Aimes and Nexus the same toilet?
They share the same core technology — Tornado Flush, CeFiONtect, Universal Height, WASHLET+ T40 compatibility, and skirted one-piece design — but they differ in profile height, rough-in flexibility, and Auto Flush readiness.
The Aimes is taller and adapts to three rough-in sizes, while the Nexus is lower, sleeker, and includes built-in Auto Flush compatibility.
Which TOTO toilet is easier to clean?
Both are far easier to clean than a two-piece toilet thanks to their skirted designs, which conceal the trapway and eliminate exterior gaps.
The Nexus’ “360 fully skirted” construction gives it a slight edge in this category, and CeFiONtect glaze on both models means waste is less likely to stick in the first place.
If you’re curious how these compare to non-electric options, our handheld bidet vs bidet seat guide covers the broader hygiene picture.
Can I add a bidet seat to both the Aimes and Nexus?
Yes — both are WASHLET+ T40 ready, which means any T40-compatible WASHLET+ bidet seat will integrate seamlessly, with the power cord and supply hose hidden inside the toilet’s built-in channel.
Our best bidets for existing toilets guide can help you find the right WASHLET+ seat to pair with either model.
Is the TOTO Aimes or Nexus better for seniors?
Both are Universal Height, which puts the seat at a comfort height similar to a standard chair — easier to sit down on and stand up from than regular toilets.
Both are also ADA compliant.
For seniors specifically, either toilet works well when paired with the right bidet seat — check out our best bidets for seniors guide for the best WASHLET+ pairings.
