1. TOTO WASHLET+ AP Wall-Hung Elongated Toilet with C5 Bidet Seat
The TOTO AP is built for homeowners who want a clean, minimalist bathroom that feels effortlessly modern.
Its fully skirted, smooth design hides every line, curve, and trapway — giving you a toilet that almost disappears into the wall for a truly seamless look.
Paired with the WASHLET C5 bidet seat and the DuoFit® in-wall tank system, you get a complete luxury bathroom package right out of the box.
Features
- Elongated, fully skirted bowl with concealed trapway for a smooth, uninterrupted silhouette
- DYNAMAX TORNADO FLUSH® — hole-free rim with dual-nozzle cyclonic flushing action
- CEFIONTECT® glaze prevents waste from sticking, keeping the bowl cleaner between scrubs
- Adjustable universal height from 15″ to 19″ for comfort and ADA accessibility
- DuoFit® in-wall tank with dual-flush push plate (1.28 GPF full / 0.9 GPF light)
- WASHLET+ C5 bidet seat included — wireless remote, PREMIST, EWATER+ wand cleaning, heated seat, air dryer, and deodorizer
- Compatible with T40 WASHLET+ system only; power cord and water supply hose concealed within wall
Pros
- Cleaner, more minimalist design than the EP — ideal for contemporary or Japandi-style bathrooms
- All-in-one bundle includes toilet bowl, WASHLET bidet seat, in-wall tank, push plate, and mounting hardware
- Saves up to 9 inches of floor space compared to floor-mounted toilets
- EWATER+ bidet wand cleaning offers exceptional hygiene without harsh chemicals
Cons
- Requires professional installation — not a DIY project
- In-wall tank system requires 2×4 or 2×6 wall framing with proper bracing
- Higher upfront cost than a standard floor-mount toilet + bidet seat setup
The AP is the right choice if you’re designing a bathroom from scratch and want everything to feel cohesive, architectural, and ultra-clean.
If you’re already deep into the world of premium bidet brands, you’ll recognize immediately why TOTO’s engineering here is in a class of its own.

2. TOTO WASHLET+ EP Wall-Hung Elongated Toilet with C5 Bidet Seat
The TOTO EP takes the same premium wall-hung platform and adds a distinctive design element — a sculpted side recess or “cutout” detail that gives the bowl a more architectural, statement-making look.
It’s a subtle difference from the AP, but for design-forward homeowners, it can be a defining one.
Like the AP, the EP comes bundled with the WASHLET C5 bidet seat and the DuoFit® in-wall dual-flush tank system, so you’re getting a full luxury toilet-and-bidet package.
Features
- Elongated bowl with distinctive side cutout recess detail for a more sculptural appearance
- DYNAMAX TORNADO FLUSH® with 1.28 GPF full flush and 0.9 GPF light flush
- CEFIONTECT® ceramic glaze for a smoother, easier-to-clean bowl surface
- Universal height adjustable from 15″ to 19″ for accessibility and comfort
- DuoFit® in-wall tank included with matte silver dual push plate
- WASHLET+ C5 bidet seat — 5 spray settings, PREMIST, EWATER+ cleaning, heated seat, warm air dryer, air deodorizer
- Concealed power cord and water supply hose via the WASHLET+ T40 system
Pros
- More visually distinctive than the AP — the side recess adds character to contemporary bathrooms
- Same powerful DYNAMAX TORNADO FLUSH and CEFIONTECT as the AP at the same performance level
- Slightly more compact external width (18½” vs AP’s standard skirted profile) for tighter spaces
- Complete bundle with WASHLET C5, in-wall tank, push plate, and all mounting hardware
Cons
- The side recess styling may not suit ultra-minimalist bathroom designs as well as the AP
- Still requires professional installation and proper in-wall framing
- Same high upfront investment as the AP bundle
The EP is the better pick if you want your toilet to be a design statement and you appreciate architecture-inspired details in your fixtures.
If you’re comparing full toilet bidet combos and care about aesthetics as much as function, the EP gives you that extra visual edge.

Design: AP vs EP — What Actually Looks Different?
This is the most important category to understand, because it’s where the AP and EP actually diverge.
The AP features a continuously smooth, fully skirted exterior — there are no interruptions, no indentations, no visible seams.
The result is a toilet that looks like a single, unbroken ceramic form when viewed from the side.
The EP, by contrast, has a noticeable side recess or “cutout” detail built into the bowl’s exterior profile.
This gives the EP a more sculpted, layered appearance — something closer to what you’d expect from European bathroom design brands.
Neither design is objectively better. But your bathroom aesthetic should drive the decision: the AP fits seamlessly into modern, spa-like spaces, while the EP works beautifully in design-forward or contemporary interiors where fixtures are meant to be noticed.
Both choices pair beautifully with a high-quality WASHLET bidet seat — and the bundled C5 seat in each package is an excellent one.
**Winner: Tie — choose based on your bathroom’s aesthetic direction.**
Flushing Performance: Does Either Have an Edge?
Here, the answer is simple — they’re identical.
Both the AP and EP use TOTO’s DYNAMAX TORNADO FLUSH® system, which sends 100% of flush water through a hole-free rim with dual nozzles.
This creates a powerful cyclonic vortex that cleans every part of the bowl without needing a visible rim channel — which is a significant hygiene advantage since rim channels are notoriously hard to clean.
Both toilets offer the same dual-flush options: 0.9 GPF for a light rinse and 1.28 GPF for heavier jobs.
And both feature the CEFIONTECT® ion-barrier glaze, which is one of the reasons TOTO toilets stay noticeably cleaner between cleanings.
If you’re coming from a standard toilet, either model will feel like a revelation.
The pros of switching to a bidet toilet combo go well beyond flushing performance — but it’s reassuring to know both AP and EP deliver equally here.
**Winner: Tie — identical flushing technology and water efficiency.**
Installation: What You Need to Know Before Buying
This is one of the most important practical considerations for either model, and they’re the same here too.
Both the AP and EP are wall-hung toilets, meaning the bowl mounts to the wall with no floor contact — and the tank is completely hidden inside the wall via the DuoFit® in-wall system.
That means you’ll need proper wall framing (2×4 or 2×6 studs), professional plumbing, and an electrical outlet nearby for the WASHLET bidet seat.
The good news: once installed, cleaning is dramatically easier than a floor-mounted toilet since there’s no base to scrub around.
Wall-hung installation also lets you set the finished bowl height anywhere from 15″ to 19″, which is a genuine accessibility benefit for households with varying needs.
If you’re already exploring bidets for seniors or people with limited mobility, the height adjustability here is a major plus.
**Winner: Tie — both require the same professional installation process.**
WASHLET C5 Bidet Seat: Included With Both
One of the smartest things about buying either the AP or EP bundle is that you get the WASHLET C5 bidet seat included.
The C5 is a mid-range TOTO WASHLET that includes: rear and front warm water cleansing, oscillating and pulsating spray modes, PREMIST bowl misting before each use, EWATER+ wand self-cleaning, a heated SoftClose seat, a warm air dryer, and an air deodorizer — all controlled via wireless remote with 2-user memory settings.
If you’ve been researching the TOTO C2 vs C5, you’ll know the C5 is the more feature-complete option and well worth the upgrade.
The WASHLET+ system also means all cords and hoses are concealed inside the wall — no visible wires, no external hose running to the seat, no cluttered aesthetic.

**Winner: Tie — both bundles include the same excellent WASHLET C5 seat.**
Space Saving: Which Fits Smaller Bathrooms Better?
Both the AP and EP wall-hung toilets save up to 9 inches of floor space compared to a traditional floor-mount toilet.
Because the tank is completely inside the wall, you only see the bowl floating off the floor — opening up the bathroom visually and making cleaning far simpler.
Looking at the bowl dimensions, the AP measures approximately 21¼” in depth and 16⅛” in width, while the EP measures 21¼” in depth and 18½” in width at its widest external point.
The EP’s side recess detail means the external width reads slightly wider in specs, though the functional footprint is comparable.
If your bathroom is genuinely tight on lateral space, the AP’s sleeker skirted profile may give you a slight advantage.
For more bathroom space-saving ideas, take a look at how wall-hung bidet toilets compare to bidet seats in terms of footprint.
**Winner: AP (slight edge) — marginally narrower skirted profile for very tight spaces.**

You’re designing a spa-like, minimalist, or Japandi-inspired bathroom where every element is clean and uncluttered.

FAQ
Q: Are the TOTO AP and EP functionally the same toilet?
Yes, almost entirely.
Both use the same DYNAMAX TORNADO FLUSH system, the same 1.28/0.9 GPF dual-flush, the same CEFIONTECT glaze, the same universal height adjustment (15″–19″), and the same WASHLET+ T40 compatibility.
The primary difference between them is the bowl’s exterior design — the AP has a smooth, fully skirted look, while the EP features a distinctive side recess detail.
Q: Do the AP and EP come with a bidet seat included?
In the WASHLET+ bundles sold on this page, yes — both are bundled with the TOTO WASHLET C5 bidet seat.
If you buy just the bowl (CT426CFG for AP, CT428CFG for EP), the seat is not included and must be purchased separately.
The C5 WASHLET bundle is the smarter buy since it ensures compatibility and conceals all cords via the WASHLET+ T40 in-wall system.
Q: Can I install the TOTO AP or EP myself?
These are not DIY installations.
Both models require a properly framed wall with 2×4 or 2×6 studs, a licensed plumber to connect the in-wall DuoFit tank and drain, and an electrician if there’s no nearby GFCI outlet for the WASHLET.
Professional installation is strongly recommended and typically required for warranty purposes.
Q: Do I need a special toilet to use a TOTO WASHLET bidet seat?
For the WASHLET+ bundles (AP+C5 and EP+C5), the bowl and bidet seat are specifically designed to work together — with the hose and power cord hidden inside the wall for a seamless look.
If you already have a standard toilet and just want a bidet seat, you can explore a standalone bidet for existing toilets without replacing the whole toilet.
Conclusion
The TOTO AP and EP wall-hung toilets are two of the finest bathroom fixtures you can buy — and choosing between them really comes down to one thing: how you want your bathroom to look.
The AP gives you that perfectly smooth, architectural minimalism that disappears into the wall.
The EP gives you a sculpted, design-forward bowl with a side detail that adds personality without compromising performance.
Both deliver TOTO’s legendary DYNAMAX TORNADO FLUSH, CEFIONTECT bowl protection, dual-flush efficiency, and the excellent WASHLET C5 bidet seat in their respective bundles.
There’s no wrong answer here.
