TOTO Drake WASHLET+ S5 — MW7763446CEG#01

The TOTO Drake WASHLET+ S5 Two-Piece Toilet pairs the two-piece Drake body at TOTO's regular height and a 1.28 GPF TORNADO FLUSH® with the WASHLET+ S5 and the wireless remote that stores each user's settings.

The remote stores its own settings for up to four people, so a shared bathroom stops being a negotiation over water temperature and pressure, and nobody has to reset the seat after somebody else has used it.

Toilet Type: Two-piece WASHLET+ toilet
Height: Regular Height Toilet
Bowl Shape: Elongated
Flush: High-efficiency TORNADO FLUSH® — single 1.28 GPF (4.8 LPF)
Rough-In: 12"
Included WASHLET: WASHLET+ S5 (SW3446)
Controls: Multifunction remote, memory for up to 4 users
Auto Flush: Not included — TOTO lists no auto-flush kit for this combination

High-efficiency TORNADO FLUSH®

TOTO's TORNADO FLUSH rinses the bowl on a single 1.28 GPF flush, which TOTO classes as high-efficiency.

CEFIONTECT® Ceramic Glaze

CEFIONTECT minimizes waste sticking to porous ceramic surfaces, which supports easier bowl cleaning between flushes.

Regular Height with a Concealed Connection

TOTO lists this Drake as a regular height toilet, and the WASHLET+ connection conceals the seat's supply line at the back of the bowl.

Adjustable Warm-Water Cleansing

Front and rear washing uses aerated warm water, oscillating and pulsating, with spray position, temperature and pressure all adjusting independently.

Heated Seat and Three-Setting Dryer

The seat is heated with its own temperature control, and the warm-air dryer offers three variable temperature settings.

Wireless Remote with Four-User Memory

The wireless remote stores personalized settings for up to four users, so each person gets their own temperature and pressure without resetting anything.

TOTO Drake WASHLET+ S5 Two-Piece Toilet - 1.28 GPF Compatibility

The TOTO Drake WASHLET+ S5 is a two-piece elongated toilet with integrated smart bidet seat. Confirm these four things before ordering:

Rough-in measurement: 12-inch standard (no 10-inch or 14-inch adapter available for this model).
Floor clearance: 21 inches in front of the bowl, 15 inches on each side.
Water supply: Standard ½-inch connection at the base of the toilet.
Electrical outlet: GFCI 120V required within 3 feet to power the integrated WASHLET+ S5 bidet seat.

Installation steps

Prep. Shut off the water supply, flush to empty the tank, then disconnect the supply line.
Remove the old toilet. Unbolt from the floor and scrape the old wax ring from the flange.
Set the wax ring. Place a new wax ring on the flange, centered over the drain.
Seat the bowl and attach tank. Lower the bowl onto the flange, press down firmly, bolt the tank to the bowl, and hand-tighten floor bolts evenly.
Connect and test. Reconnect the supply line, restore water, and plug the WASHLET+ S5 into the GFCI outlet.

TORNADO FLUSH® at 1.28 GPF

TOTO builds this Drake on its TORNADO FLUSH system, which the sheet describes as high-efficiency at 1.28 GPF.

This is a single-flush toilet: one volume, 1.28 GPF (4.8 LPF), with no reduced-flush setting to choose between.

The flush is operated by a chrome plated trip lever on the side of the tank, and the trap measures 2-1/8" across.

CEFIONTECT® Glaze on a Two-Piece Drake

CEFIONTECT ceramic glaze minimizes waste from sticking to porous ceramic surfaces, supporting easier bowl cleaning between flushes.

This is a two-piece toilet, so the tank and bowl are separate components: the C776CEGT40 elongated bowl with the ST776EA tank.

TOTO lists this model as a regular height toilet. The WASHLET+ supply connection is concealed for a seamless installation.

Adjustable Warm-Water Cleansing with Heated Seat and Dryer

The S5 fitted to this regular height Drake cleanses front and rear using gentle aerated warm water, with both oscillating and pulsating features.

Spray position, water temperature and water pressure each adjust on their own, and the water range runs 95ºF–104ºF.

An instantaneous water heater supplies continuous warm water, the seat is heated across 82ºF–97ºF, and the warm air dryer offers three variable settings.

EWATER+®, PREMIST® and a Wireless Remote with User Memory

EWATER+ auto-cleans the wand after every use, and PREMIST automatically mists the bowl before each one.

The wand also cleans itself inside and out before and after every use.

Controls are handled by a multifunction remote control with personalized memory settings for up to 4 users, and CLEAN RESIN keeps the wand and seat easier to maintain. Night light illuminates the inside of the bowl.
