TOTO Aurora Washlet+ S7 — MW6864726CEFG#01

The TOTO Aurora Washlet+ S7 is the elongated, completely skirted one-piece Aurora toilet supplied with the Washlet S7 bidet seat, flushing at 1.28 GPF on TOTO's INTEGRAVITY SYSTEM™.

The S7 moves beyond the S5 with five warm-air dryer settings and EWATER+® cleaning for both the wand and the bowl. It is operated from a wireless remote control with personalized memory settings for up to four users.

Toilet Type: One-piece Washlet+ toilet
Bowl Shape: Elongated, completely skirted
Flush: INTEGRAVITY SYSTEM™ — 1.28 GPF (4.8 LPF)
Rough-In: 12" (10" and 14" options available at additional cost)
Seat Height: 17 3/16"
Included Washlet: Washlet S7
Controls: Wireless remote, memory settings for up to 4 users

INTEGRAVITY SYSTEM™

A dual-tank, dual-valve architecture sequences the rim wash and the siphon jet. TOTO states that INTEGRAVITY rinses the bowl 5× longer compared with conventional toilets.

Completely Skirted Washlet+ Design

The toilet is one-piece with a completely skirted exterior, and the Washlet+ connection is concealed, so no protruding pipes or cords are visible.

CEFIONTECT® and PREMIST®

PREMIST wets the surface of the bowl before use, aiding in the removal of waste, and CEFIONTECT glaze prevents debris and mold from sticking to the ceramic.

Instantaneous Warm-Water Cleansing

Front and rear washing, oscillating and pulsating modes, and adjustable spray position, temperature and pressure — with water heated on demand rather than held in a tank.

Heated Seat and Warm-Air Dryer

The seat is heated and its temperature is adjustable. The warm-air dryer has five settings, the count TOTO gives the S7 and the S7A.

EWATER+ Wand & Bowl

EWATER+® uses electrolyzed water to keep both the wand and the toilet bowl hygienic on the S7, and the wand also cleans itself after every use.

TOTO Aurora S7 Compatibility

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

Rough-in measurement: 12-inch standard. 10"/14" 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.
Electrical outlet: GFCI 120V within 3 feet (powers integrated WASHLET+ 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.
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.

Frequently Asked Questions about TOTO Aurora S7

What is the difference between the WASHLET S7 and the S7A?

One feature. The S7A adds an automatic open and close lid. EWATER+ in the bowl and on the wand, four wash modes, the five-setting dryer, the high-output deodorizer, the auto-sensing night light, the skin-contact sensor and the 4.1-inch profile are identical on both.

What does EWATER+ in the bowl actually do?

On the S7 and S7A, electrolyzed water mists the bowl after every use and on a timer when the toilet has been unused, and a button on the remote triggers it manually. On the S2 and S5, EWATER+ cleans the wand only. Combined with the CEFIONTECT glaze, the bowl misting is what keeps the ceramic looking clean between cleans.

Should I choose the 1.28 GPF Aurora or the other version?

The two are only about twelve dollars apart, so this is not a cost decision. Choose 1.28 GPF if you have a long horizontal drain run with minimal fall, older cast-iron pipe, or this is the only fixture on that branch, because an ultra-low-flow toilet has less water available to carry solids the full distance. Otherwise the 1.0 GPF Aurora 1G is fine and uses roughly 22% less water per flush.

What makes a WASHLET+ toilet different from a standard bidet seat installation?

WASHLET+ is a matched pair. The bowl has a channel cast into the back of it, and the seat runs its power cord and water hose rearward into that channel rather than out of the side. Nothing is visible from the front or the side. An ordinary bidet seat added later will work on this bowl, but its cord and hose will run across the skirt in plain view.

What are the downsides of the Aurora WASHLET+ S7?

The main limitations are that INTEGRAVITY launched in February 2026 and has no long-term field record yet, the warranty is one year rather than the two or three some competitors offer, and the toilet ships with a left-hand trip lever, so ADA compliance requires either a right-hand lever or auto flush. The Ebony finish also ships without CEFIONTECT glaze while costing more than Cotton White. At 132 lbs boxed this is a two-person installation.

What Makes the TOTO Aurora One-Piece Design Different?

The Aurora toilet is a single one-piece unit with an elongated bowl.

Its exterior is completely skirted, which TOTO describes as a sleek and understated look that's easier to clean.

Being a Washlet+ model, the supply connection is concealed, so no protruding pipes or cords are on show.

The standard rough-in is 12 inches, and 10-inch and 14-inch options are available at additional cost.

What Makes the Aurora's INTEGRAVITY Flush Different?

Every Aurora runs on the INTEGRAVITY SYSTEM™, a gravity-driven flush engine TOTO states is exclusive to the series.

Two tanks and two valves let it sequence the rim wash and the siphon jet.

TOTO states that INTEGRAVITY rinses the bowl 5× longer compared with conventional toilets, using 1.28 gallons per flush.

The bowl itself is TORNADO FLUSH®: two nozzles, a centrifugal cyclonic rinsing action and a hole-free rim.

CEFIONTECT® glaze prevents debris sticking to the ceramic, and PREMIST® wets the bowl before each use.

What Does the Washlet S7 Add?

The Washlet S7 washes front and rear, with oscillating and pulsating modes.

Spray position, water temperature and water pressure all adjust, and the water is heated on demand rather than stored.

The seat is heated, and the warm-air dryer has five settings.

EWATER+® cleans both the wand and the toilet bowl, and the wand also cleans itself.

A wireless remote control holds memory settings for up to four users.

Which TOTO Aurora Washlet Should You Choose: S2, S5, S7 or S7A?

All four use the same 1.28 GPF Aurora toilet, so the main choice is which Washlet goes on top.

All four share the core cleansing and comfort functions: washing, instantaneous heating, a heated seat and a dryer.

Choose the S2 if… you want the core Washlet cleansing and comfort functions and are comfortable using the arm-mounted control panel.
Choose the S5 if… you want that core experience with a wireless remote and memory for up to four users.
Choose the S7 if… you want five dryer settings instead of three, and EWATER+® cleaning for both the wand and the bowl.
Choose the S7A if… you want the S7 feature set plus the touchless automatic open/close lid.
S2 → S5: arm panel becomes a wireless remote with 4-user memory.
S5 → S7: three dryer settings become five, and EWATER+® adds bowl cleaning.
S7 → S7A: adds the touchless automatic open/close lid.

Separate auto-flush Aurora configurations are available for S7 and S7A; the four SKUs covered here do not include auto flush.

What do you get with the TOTO Aurora Washlet+ S7?

The TOTO Aurora Washlet+ S7 is sold as a single combination SKU, MW6864726CEFG#01, pairing the Aurora one-piece toilet with the Washlet S7 in Cotton.

It uses 1.28 GPF and fits a standard 12-inch rough-in, with 10-inch and 14-inch rough-ins costing extra.

This is the Aurora configuration for a buyer who wants five dryer settings and EWATER+® on the bowl as well as the wand.
