TOTO Drake WASHLET+ S7 — MW7764726CEGA#01

The TOTO Drake WASHLET+ S7 Two-Piece Toilet is a two-piece Drake at TOTO's regular height flushing at 1.28 GPF, carrying the WASHLET+ S7 — the tier where EWATER+ starts cleaning the bowl as well as the wand.

The auto-flush configuration adds TOTO's THU857 kit so the toilet flushes on its own, and the block-style remote handles everything else from across the room. The standard configuration is the same toilet and the same seat without that kit.

Toilet Type: Two-piece WASHLET+ toilet
Height: Regular Height Toilet — seat height 16" [407mm]
Bowl Shape: Elongated
Flush: High-efficiency TORNADO FLUSH® — single 1.28 GPF (4.8 LPF)
Rough-In: 12"
Included WASHLET: WASHLET+ S7 (SW4726AT40)
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 S7 cleanses front and rear with aerated warm water, oscillating and pulsating, and its water range starts lower than the S2 and S5 at 86ºF.

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.

EWATER+ on the Wand and the Bowl

EWATER+ cleans the wand and the bowl after every use on the S7, where the S2 and S5 clean the wand only — that is the real step up between the tiers.

TOTO Drake Washlet+ S7 Two-Piece Compatibility

The TOTO Drake WASHLET+ S7 is a two-piece elongated smart toilet with an integrated bidet seat. Confirm these four things before ordering:

Rough-in measurement: 12-inch standard installation.
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 the integrated WASHLET+ S7 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. Lower onto the flange, press down firmly, and hand-tighten the bolts evenly.
Attach the tank and test. Bolt the tank to the bowl, reconnect the supply line, and plug the S7 into the GFCI outlet.

Frequently Asked Questions about TOTO Drake S7 MW7764726CEGA

What is the difference between Toto Drake and Drake 2?

The difference between Toto Drake and Drake 2 is that the Drake 2 has a more updated design and improved flushing system, while the original Drake is a more basic and classic model.

What is the difference between TOTO WASHLET and washlet+?

The difference between TOTO WASHLET and Washlet+ is that Washlet+ is designed to pair with specific TOTO toilets to hide cords and hoses for a cleaner look.

What's the difference between the TOTO S7 and S7A?

The difference between the TOTO S7 and S7A is that the S7A includes an automatic lid and added convenience features, while the S7 focuses on the core cleaning and comfort functions.

Why is Toto Drake so good?

The Toto Drake is so good because it combines a powerful flush, reliable performance, and an easy-to-clean design for everyday use.

Is the Toto Drake loud?

The Toto Drake is not loud because it uses a smooth and efficient flush system that keeps noise levels lower than many standard toilets.

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, with a seat height of 16" [407mm]. The WASHLET+ supply connection is concealed for a seamless installation.

Adjustable Warm-Water Cleansing with Heated Seat and Dryer

The S7 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.

EWATER+® on the Wand and Bowl with Remote Convenience

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.

Controls are handled by a multifunction pearl white block-style remote control, and CLEAN RESIN keeps the wand and seat easier to maintain. Night light.

What do you get with the Drake WASHLET+ S7?

This is combination MW7764726CEGA#01: the two-piece Drake with the C776CEGT40 elongated CEFIONTECT bowl, the ST776EA tank, and the SW4726AT40 WASHLET+ S7, in Cotton.

TOTO lists it as a regular height toilet — not Universal Height — and it flushes once at 1.28 GPF (4.8 LPF), with a seat height of 16" [407mm].

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.
