TOTO Aquia IV WASHLET+ S7 — MW4464726CEMFGNA#01

The TOTO Aquia IV 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
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.

Frequently Asked Questions about TOTO Aquia IV S7 MW4464726CEMFGNA

The height of the TOTO Aquia IV is universal height, which is designed to be more comfortable for most adults when sitting and standing.

What's the difference between TOTO WASHLET and washlet+?

The difference between a TOTO Washlet and Washlet+ is that Washlet+ is made to pair with specific TOTO toilets so the cords and hoses stay hidden for a cleaner look.

How to know if toto washlet will fit?

You can know if a TOTO Washlet will fit your toilet by checking if you have an elongated bowl and the right mounting space behind the seat. Most TOTO models are designed to fit standard setups.

Is the TOTO Aquia IV a good toilet?

The TOTO Aquia IV is a good toilet because it has a powerful dual flush system, an easy-to-clean design, and works well with modern Washlet bidet seats.

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 CT446CEFGNT40 bowl and the ST446EMNA tank.

Adjustable Warm-Water Cleansing with Heated Seat and Dryer

The S7 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+® 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 illuminates the side and the inside of the bowl.
