TOTO Aquia IV Cube WASHLET+ S7 — MW4364726CEMFGNA#01

The TOTO Aquia IV Cube WASHLET+ S7 Two-piece Toilet is a completely skirted two-piece toilet with dual-flush DYNAMAX TORNADO FLUSH® and the WASHLET+ S7, the tier where EWATER+ starts cleaning the bowl as well as the wand.

The auto-flush configuration adds TOTO's THU855 kit so the toilet flushes on its own, and the multifunction pearl white 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 (Aquia IV Cube)
Height: Universal Height
Bowl Shape: Elongated, completely skirted
Flush: DYNAMAX TORNADO FLUSH® — 1.28 / 0.9 GPF
Rough-In: 12" standard; optional 10" (TSU48.10) and 14" (TSU48.14)
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 (THU855 kit); available as an upgrade on the standard model

DYNAMAX TORNADO FLUSH® with Dual Flush

TOTO's DYNAMAX TORNADO FLUSH uses 360º cleaning power to reach every part of the bowl, and you pick 1.28 GPF for a full flush or 0.9 GPF for a reduced one.

CEFIONTECT® Ceramic Glaze

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

Completely Skirted WASHLET+ Design

The skirted exterior gives you a flat surface to wipe rather than a contoured trapway, and the WASHLET+ connection conceals the seat's supply line.

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 Aquia IV Cube Washlet+ S7 Two-Piece Compatibility

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

Rough-in measurement: 12-inch standard. 10-inch and 14-inch supported with TSU01W adapter (sold separately).
Floor clearance: 21 inches in front of the bowl, 15 inches on each side.

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 the tank. Lower the bowl onto the flange, press down firmly, hand-tighten bolts evenly, then bolt the tank to the bowl.
Connect and test. Reconnect the supply line, restore water, and plug the bidet cord into the GFCI outlet.

DYNAMAX TORNADO FLUSH® with 1.28 / 0.9 GPF Dual Flush

TOTO states that DYNAMAX TORNADO FLUSH utilizes 360º cleaning power to reach every part of the bowl.

You get two flush volumes: 1.28 GPF for a full flush and 0.9 GPF for the reduced flush, which TOTO classes as ultra high-efficiency.

CEFIONTECT® with a Completely Skirted WASHLET+ Design

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

TOTO describes the completely skirted design as a sleek and understated look that is easier to clean, with no contoured trapway to wipe around.

The Cube is the squared-off member of the Aquia IV family and uses its own tank casting, the ST436EMNA.

Adjustable Warm-Water Cleansing with Heated Seat and Dryer

Paired with the Cube, the S7 provides front and rear cleansing in gentle aerated warm water, oscillating and pulsating.

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+ auto-cleans the wand and the bowl after every use, with PREMIST wetting the bowl ahead of each use.

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 illuminates the side and the inside of the bowl.
