TOTO Nexus WASHLET+ S7 — MW6424726CEFGA#01

The TOTO Nexus WASHLET+ S7 One-Piece Toilet is a completely skirted one-piece toilet on TORNADO FLUSH® 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: One-piece WASHLET+ toilet
Height: Universal Height
Bowl Shape: Elongated, completely skirted
Flush: High-efficiency TORNADO FLUSH® — single 1.28 GPF (4.8 LPF)
Rough-In: 12" standard; 14" option available
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.

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 Nexus Washlet+ S7 One Piece 1.28 GPF Compatibility

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

Rough-in measurement: 12-inch standard. 14-inch rough-in available upon request.
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 new toilet. Lower onto the flange, press down firmly, and hand-tighten the bolts evenly.
Connect and test. Reconnect the supply line, restore water, and plug into the GFCI outlet.

TOTO Nexus Washlet+ S7 One Piece 1.28 GPF

TORNADO FLUSH® at 1.28 GPF

TOTO builds this Nexus 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, the trap measures 2-1/8" across, and the bowl sets on a standard 12" rough-in with a 14" option.

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.

Because this is a one-piece toilet there is no seam between tank and bowl to wipe along, and TOTO lists the bowl as CST642CEFGAT40.

Adjustable Warm-Water Cleansing with Heated Seat and Dryer

On this one-piece Nexus the S7 cleanses front and rear with gentle aerated warm water, with 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 mists the bowl before every 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.
