TOTO Nexus 1G WASHLET+ S7A — MW4424736CUFGA#01

The TOTO Nexus 1G WASHLET+ S7A Two-Piece Toilet puts TOTO's top-tier WASHLET+ S7A on a completely skirted two-piece body flushing at 1.0 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: Ultra high-efficiency TORNADO FLUSH® — single 1.0 GPF (3.8 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 (THU856 kit); available as an upgrade on the standard model

Ultra high-efficiency TORNADO FLUSH®

TOTO's TORNADO FLUSH rinses the bowl on a single 1.0 GPF flush, which TOTO classes as ultra 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 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 rough-ins supported with TSU01W adapter (sold separately).
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 required to power the integrated S7A 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 opening.
Seat the bowl and attach tank. Lower the bowl onto the flange, press down firmly, bolt the tank to the bowl, then hand-tighten floor bolts evenly.
Connect and test. Reconnect the supply line, restore water, and plug the WASHLET+ S7A into the GFCI outlet.

Frequently Asked Questions about TOTO Nexus S7A MW4424736CUFGA

Is the TOTO Nexus a good toilet?

The TOTO Nexus is a good toilet because it offers strong flushing performance, a sleek skirted design, and compatibility with high-end WASHLET features.

What is a TOTO S7A?

A TOTO S7A is a premium WASHLET bidet seat with advanced features like an automatic open and close lid, heated seat, warm water wash, and self-cleaning technology.

What toilets are compatible with TOTO S7A?

Toilets compatible with the TOTO S7A are models designed for WASHLET+ systems, allowing hidden connections for a clean and seamless installation.

How tall is the Toto Nexus toilet?

The Toto Nexus toilet comes in universal height, which is slightly taller than standard toilets for more comfortable sitting and standing.

TORNADO FLUSH® at 1.0 GPF

TOTO builds this Nexus 1G on its TORNADO FLUSH system, which the sheet describes as ultra high-efficiency at 1.0 GPF.

This is a single-flush toilet: one volume, 1.0 GPF (3.8 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 ST442UA tank.

Adjustable Warm-Water Cleansing with Heated Seat and Dryer

On the two-piece Nexus 1G, the S7A handles front and rear cleansing with 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+®, PREMIST® and the Touchless Auto Open/Close Lid

EWATER+ auto-cleans the wand and the bowl after every use, and PREMIST puts a film of water in the bowl before you sit down.

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.
