TOTO Washlet+ Drake II + S550e Integrated Smart Toilet Combo

The Washlet+ Drake II combo positioning

The Washlet+ Drake II + S550e combo (MW4543046CEFGA) is TOTO's strategic alternative to the Neorest line — Drake II bowl + Washlet S550e electronic seat sold as a single factory-engineered SKU rather than as separate components. At $2,280-$2,780, the combo delivers approximately 80% of the Neorest 700H smart-toilet experience at half the price ($4,180-$4,880).

The "Washlet+" designation matters. TOTO sells Washlet seats (C5, K300, S350e, S550e) as standalone aftermarket replacement seats that fit virtually any TOTO bowl. The Washlet+ designation indicates the seat is pre-engineered for a specific bowl — in this case, the Drake II — with the spray nozzle position calibrated to the bowl geometry, the auto-deodorizer ducting aligned to the bowl rim, and the seat-to-bowl interface optimized for a clean visual fit. You can buy a Drake II + Washlet S550e separately and assemble them, but the Washlet+ combo eliminates the integration guesswork.

What "Washlet+" actually means engineering-wise

A standard Drake II + standalone Washlet S550e combination works fine — TOTO designed all current bowls and Washlet seats to be cross-compatible. The Washlet+ designation adds:

• Pre-calibrated nozzle position — the S550e wash nozzles hit the optimal spray pattern for the Drake II bowl shape, not just "any TOTO bowl shape."
• Optimized auto-flush sensor calibration for the Drake II's flush valve actuation (the S550e auto-flush feature)
• Tighter visual fit — the seat-to-bowl gap is minimized vs aftermarket Washlet install
• Single SKU warranty coverage — bowl + seat handled as one product
• Pre-installed water-supply tee adapter for the wash function

For owners who don't care about these refinements, buying a Drake II separately + S550e separately is equally functional and ~$200 cheaper combined.

The feature set — what you actually get

The Washlet+ Drake II + S550e combo combines two products into one experience:

From the Drake II bowl:

• Double Cyclone flush — two angled jet nozzles creating centrifugal vortex bowl-cleansing
• CeFiONtect glaze — hydrophobic ceramic surface, extended cleaning intervals
• 1.28 GPF WaterSense certified
• 1,000g+ MaP score — stronger flush than Neorest's 800g (the Drake II bowl is the stronger-flushing TOTO)
• Universal Height 17.25" ADA-compliant
• Two-piece serviceability — tank and bowl can be serviced separately

From the Washlet S550e seat:

• Heated seat with temperature adjustment + eco-mode
• Instant-heat water for the bidet wash (no tank-warmup wait)
• Integrated bidet wash — rear wash, front wash (feminine cleansing), oscillating wash, temperature-adjustable, pressure-adjustable, nozzle-position-adjustable
• Warm-air dryer with 5 temperature settings
• Auto open/close lid with motion sensor
• Auto-deodorizer with carbon filter
• EWATER+ pre-use bowl mist — ionized electrolyzed water sanitization
• Self-cleaning wand — the wash nozzle cleans itself before and after each use
• Soft-light night LED ring under the seat for nighttime use
• Wireless remote control wall-mount for all functions

What you give up vs Neorest 700H

• The tankless silhouette. The Washlet+ Drake combo is a traditional two-piece bowl + tank with a Washlet seat on top. The Neorest is a single tankless integrated unit. Visual: Washlet+ Drake looks like "a toilet with a smart seat"; Neorest looks like "a designer fixture."
• The foot-sensor flush. The Drake II uses a standard chrome trip lever; flushing is a manual handle press. Neorest has foot-sensor or auto-flush.
• The seamless seat-to-bowl interface. Washlet+ has a visible seam between bowl rim and Washlet seat; Neorest has a flush integrated seam.
• ACTILIGHT UV pre-mist. Washlet S550e has EWATER+ post-use mist but NOT the additional ACTILIGHT UV that Neorest 750H/NX1/NX2 add.
• Dual-flush capability. The Drake II bowl is single-flush 1.28 GPF; Neorest is dual-flush 0.8/1.0 GPF.

The variant matrix

The "Classic" vs "Contemporary" design refers to the Washlet S550e seat exterior styling — Classic has more traditional curves, Contemporary has sharper geometric lines. Functionally identical.

What's in the box

• Drake II bowl (CST454CEFG body)
• Drake II tank with Double Cyclone flush mechanism
• Washlet S550e electronic seat unit
• Wireless wall-mount remote control + mounting hardware
• Water-supply tee adapter (for splitting flow between tank fill and wash function)
• S550e power cord (~6 feet, plugs into GFCI outlet)
• Tank-to-bowl gasket and brass bolts
• Seat-to-bowl mounting hardware (color-matched bolts and grippers)
• Wax ring NOT included
• Installation manual covering both bowl install and Washlet seat install

Install requirements (the GFCI is still required)

• GFCI electrical outlet within 3 feet of the toilet base — same as Neorest. Required.
• Standard 12" rough-in.
• 3/8" compression-fit water supply with the included tee adapter.
• Total weight: ~125 lbs across two boxes (Drake II bowl + tank = ~85 lbs; S550e seat = ~40 lbs). Much easier to handle than Neorest's 140 lb single unit.
• Standard 12" floor flange; floor doesn't need to be perfectly flat (more forgiving than Neorest).

Install procedure (90 minutes for someone with plumbing comfort)

1. Standard Drake II two-piece install — see Drake II install walkthrough. ~60 minutes.
2. Install water-supply tee adapter between angle stop and tank fill connection.
3. Mount the Washlet S550e seat to the bowl using included color-matched bolts (replaces the SoftClose seat that would otherwise come on a standalone Drake II).
4. Connect the Washlet's water supply line to the tee adapter.
5. Plug the Washlet power cord into the GFCI outlet.
6. Pair the wireless remote control with the seat (button-press combination from manual).
7. Test all functions: flush (trip lever), wash (remote button), dryer (remote), heated seat (auto-on when seated), lid auto-open (motion-sensor).

The total cost picture (US, all-in)

• Washlet+ Drake II + S550e combo: $2,280-$2,580
• GFCI outlet installation (if not present): $200-$450
• Wax ring + minor plumbing supplies: $15-$25
• Plumber labor (if not DIY): $250-$450
• Total turnkey: $2,495-$3,505

What owners report (3-15 year ownership)

• The Washlet S550e + Drake II combination is genuinely the smart-toilet experience at a third of Neorest cost. Heated seat, integrated wash, dryer, auto-lid — all the features people fall in love with — present and well-engineered.
• The visible seam between Drake II tank and Washlet seat is the aesthetic compromise. Some owners don't notice; others wish they'd spent the additional $1,500-$2,500 for Neorest.
• Drake II's Double Cyclone flush outperforms Neorest's flush in MaP testing (1,000g+ vs 800g). Real-world bowl-cleansing on the combo is actually stronger than on a Neorest.
• Service is easier than Neorest. Bowl + tank serviced as standard TOTO Drake II (universal aftermarket parts available everywhere). Washlet seat serviced separately or replaced as a module if electronics fail.
• Washlet S550e service life: 10-15 years. When the wash pump or control board fails (eventually), replacement is module-level — typically $400-$700 vs Neorest's $500-$1,000 module replacement.
• Drake II porcelain service life: 25-30 years. Same as standalone Drake II.
• The flexibility advantage: if the Washlet S550e fails after warranty, you can replace just the seat — keeping the Drake II bowl and tank as functional standard toilet. Neorest failure typically means full unit replacement.
• Most-cited reason to choose Washlet+ Drake over Neorest: the $1,500-$2,500 savings + the modular service path. Most-cited reason to choose Neorest over Washlet+: the integrated visual silhouette and tankless aesthetic.

Where the Washlet+ Drake combo wins vs Neorest

• Lower price — $2,280-$2,580 vs $4,180-$4,880 (Neorest 700H). Saving $1,500-$2,500.
• Stronger flush performance — Drake II's 1,000g+ MaP vs Neorest's 800g.
• Modular serviceability — seat and bowl handled separately. Failure of one doesn't require replacing the other.
• Easier install — two lighter components vs Neorest's 140 lb single unit.
• Broader service network — Drake II + Washlet are serviced by far more plumbers than the Neorest-certified-only network.
• Universal aftermarket parts for the bowl side — flapper, fill valve, supply line are universal.

Where Neorest wins vs Washlet+ Drake

• Integrated tankless silhouette — the visual aesthetic that's the Neorest signature
• Foot-sensor flush + auto-flush — Drake II uses standard trip lever
• Tankless design — lower total height (~22" vs Drake II's 28-30")
• Dual-flush 0.8/1.0 GPF for water-conservation households (Drake II is single-flush 1.28 GPF)
• ACTILIGHT UV pre-mist on Neorest 750H/NX1/NX2 (Washlet+ has EWATER+ but not ACTILIGHT)
• Resale value perception — "Neorest" carries more brand cachet than "Washlet+ Drake combo" in luxury real-estate listings

Where Washlet+ Drake competes against other smart toilets

The verdict — should you buy the Washlet+ Drake II + S550e combo?

Buy if:

• You want the Neorest smart-toilet experience without the Neorest price tag
• You value modular serviceability (seat and bowl handled separately)
• You prefer stronger flush performance — Drake II's Double Cyclone outperforms Neorest's flush mechanism
• You're OK with the visible seam between tank and seat (vs Neorest's seamless integrated silhouette)
• The $1,500-$2,500 savings is meaningful
• You want broader service network coverage

Choose Neorest 700H/750H instead if:

• The tankless integrated silhouette is the buying reason
• You want foot-sensor flush + auto-flush + tankless aesthetic
• Master bath in $1M+ residence where "Neorest" carries documented brand cachet
• Dual-flush 0.8/1.0 GPF water conservation matters more than Drake II's stronger flush

Choose standalone Drake II + S550e separately if you want to save another $200 and don't care about the pre-engineered Washlet+ integration.

Warranty

TOTO Washlet+ Drake II + S550e combo residential warranty: 1 year on tank trim, 2 years on Washlet electronics, lifetime on porcelain. The Washlet seat is serviced as a TOTO Washlet product (separate service workflow from the Drake II bowl). Combo warranty is administered by TOTO USA as a single SKU but service routing depends on which component needs attention.

Pricing reality (2026)

Washlet+ Drake II + S550e MW4543046CEFGA (Cotton White Classic): $2,280-$2,580. Ferguson and Build.com Pro Desk: $2,080-$2,280. Home Depot: $2,499-$2,699 standard. Holiday sales periodically drop to $1,880-$2,080. Sedona Beige and Bone variants +$200-$300.

The honest summary

The Washlet+ Drake II combo is the smart move for the buyer who wants every Washlet S550e feature + premium TOTO bowl quality but doesn't want to pay the $1,500-$2,500 premium for the tankless integrated Neorest silhouette. It's the value-pick within TOTO's smart-toilet lineup — and the choice that most US owner-occupied premium bathroom remodels under $30,000 actually end up selecting once buyers see both options.
