TOTO Drake WASHLET+ S7 — MW7764726CEFGA#01

The TOTO Drake WASHLET+ S7 Two-Piece Toilet - Universal Height is a two-piece Drake at Universal 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: Universal Height
  • 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.

Universal Height with a Concealed Connection

TOTO lists this Drake at Universal Height, 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 - Universal Height Compatibility

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

  • Rough-in measurement: 12-inch standard connection to the floor drain. (Optional 10 inch adapter)
  • 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 bowl.
  • Electrical outlet: GFCI 120V within 3 feet of the tank (powers the integrated WASHLET+ S7 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 bowl. Lower the bowl onto the flange, press down firmly, and hand-tighten the bolts evenly.
  5. Attach the tank and test. Bolt the tank to the bowl, reconnect the supply line, and plug the bidet seat into the GFCI outlet.

CEFIONTECT® Glaze on a Two-Piece Drake
