TOTO Aquia IV WASHLET+ S7A — MW4464736CEMGNA#01

The TOTO Aquia IV WASHLET+ S7A Two-piece Toilet is a completely skirted two-piece toilet with dual-flush DYNAMAX TORNADO FLUSH® and TOTO's top-tier WASHLET+ S7A, 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 flush kit only if you want it later.

Toilet Type: Two-piece WASHLET+ toilet
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+ S7A (SW4736AT40)
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 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 Aquia IV Washlet+ S7A 2 Piece Toilet - 1.28 GPF & 0.9 GPF

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.

The flush is operated by a chrome plated push-button, and the trap measures 2-1/4" across.

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 CT446CEGNT40 bowl and the ST446EMNA tank.

Adjustable Warm-Water Cleansing with Heated Seat and Dryer

The S7A fitted to this Aquia IV 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 mists the bowl before every use.

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 night light illuminates the side and the inside of the bowl.
