TOTO Nexus WASHLET+ S7A — MW4424736CEFGA#01

The TOTO Nexus WASHLET+ S7A Two-Piece Toilet puts TOTO's top-tier WASHLET+ S7A on a completely skirted two-piece body flushing 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: 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+ 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.

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 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 Nexus Washlet+ S7A Two-Piece Compatibility

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

Rough-in measurement: 12-inch standard, with a 14-inch option available. A 10-inch rough-in is not available for this model.
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 WASHLET+ S7A bidet seat and auto-flush).

Installation steps

Prep. Shut off 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 the WASHLET+ into the GFCI outlet.

Frequently Asked Questions about TOTO Nexus S7A MW4424736CEFGA

Is the TOTO Nexus a good toilet?

The TOTO Nexus is a good toilet because it offers strong flushing performance, an easy-to-clean design, and compatibility with WASHLET bidet seats.

What is the difference between TOTO Washlet S7 and S7A?

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

How tall is the Toto Nexus toilet?

The TOTO Nexus toilet is built at a universal height, making it more comfortable for most adults to sit and stand.

Does TOTO Nexus have tornado flush?

The TOTO Nexus does have Tornado Flush, which provides a powerful and efficient clean with every flush.

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.

This is a two-piece toilet, so the tank and bowl are separate components: the CT442CUFGT40 bowl with the ST442EA tank.

Adjustable Warm-Water Cleansing with Heated Seat and Dryer

The S7A fitted to this two-piece Nexus 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+®, 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.

What do you get with the Nexus WASHLET+ S7A?

This is combination MW4424736CEFGA#01: the Nexus two-piece toilet with the CT442CUFGT40 elongated CEFIONTECT bowl, the ST442EA tank, and the SW4736AT40 WASHLET+ S7A, in Cotton.

It is Universal Height, flushes once at 1.28 GPF (4.8 LPF), and sets on a 12" rough-in with a 14" option available.

The two-piece set also lists TOTO's 9AU321-A WASHLET Adaptor, the part that makes the concealed WASHLET+ connection at the tank.

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.
