TOTO Drake WASHLET+ S7A — MW7764736CEGA#01

The TOTO Drake WASHLET+ S7A Two-Piece Toilet puts TOTO's top-tier WASHLET+ S7A on a two-piece Drake body at TOTO's regular height that flushes at 1.28 GPF, and it is the only seat in the range with a touchless lid.

Choose the auto-flush configuration and the toilet flushes itself while the lid opens and closes untouched, so an ordinary visit needs no contact with the fixture at all; the standard configuration keeps the same seat and adds the kit only if you want it later.

  • 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+ S7A (SW4736AT40)
  • Controls: Multifunction pearl white block-style remote, memory for up to 4 users
  • Auto Flush: Included with the auto-flush model (THU857 kit); available as an upgrade on the standard model

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

The S7A washes front and rear with aerated warm water, with oscillating and pulsating modes and independently adjustable position, temperature and pressure.

Heated Seat and Five-Setting Dryer

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

Touchless Auto Open/Close Lid

The S7A is the only WASHLET tier with a touchless auto open/close lid, which is what separates it from the otherwise closely matched S7.

TOTO Drake Washlet+ S7A Two-Piece 1.28 GPF Compatibility

The TOTO Drake Washlet+ S7A is a two-piece elongated toilet with integrated smart bidet seat. Confirm these four things before ordering:

  • Rough-in measurement: 12-inch standard.
  • 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 within 3 feet (powers integrated WASHLET+ S7A bidet seat).

Installation steps

  1. Prep. Shut off the water supply, flush to empty the tank, then disconnect the supply line.
  2. Remove the old toilet. Unbolt from the floor and scrape the old wax ring from the flange.
  3. Set the wax ring. Place a new wax ring on the flange, centered over the drain.
  4. Seat the new toilet. Lower the bowl onto the flange, press down firmly, and hand-tighten the bolts evenly.
  5. Attach the tank and connect. Bolt the tank to the bowl, reconnect the supply line, restore water, and plug into the GFCI outlet.

Frequently Asked Questions about TOTO Drake S7A MW7764736CEGA

Why is TOTO Drake so good?

TOTO Drake is good because it combines powerful flushing, easy-to-clean surfaces, and a reliable bidet system for a comfortable and hygienic experience.

Is the TOTO Drake loud?

TOTO Drake Washlet+ S7A Two-Piece 1.28 GPF

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.

  • High-efficiency TORNADO FLUSH system
  • Single 1.28 GPF (4.8 LPF) flush
  • Chrome plated trip lever flush control

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.

  • CEFIONTECT glazed elongated bowl
  • Two-piece tank and bowl construction
  • Concealed WASHLET+ supply connection

Adjustable Warm-Water Cleansing with Heated Seat and Dryer

The S7A 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 86ºF–104ºF.

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

  • Front and rear aerated warm water
  • Oscillating and pulsating spray modes
  • Five-setting warm air dryer

EWATER+®, PREMIST® and the Touchless Auto Open/Close Lid

EWATER+ auto-cleans the wand and the bowl 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.

The S7A is the only tier with a touchless auto open/close lid, driven by a multifunction pearl white block-style remote control that stores each user's settings. CLEAN RESIN keeps the wand and seat easier to maintain, and a night light is fitted.

  • EWATER+ on the wand and bowl
  • PREMIST before every use
  • Touchless auto open/close lid

What do you get with the Drake WASHLET+ S7A?

This is combination MW7764736CEGA#01: the two-piece Drake with the C776CEGT40 elongated CEFIONTECT bowl, the ST776EA tank, and the SW4736AT40 WASHLET+ S7A, in Cotton.

TOTO lists it as a regular height toilet — not Universal Height — and it flushes once at 1.28 GPF (4.8 LPF).

The bowl sets on a 12" rough-in and the trap measures 2-1/8" across.

The auto-flush model adds TOTO's THU857 Auto Flush Kit; the standard model does not include it, and TOTO lists it as an available upgrade.
