TOTO Aurora Washlet+ S2 — MW6863346CEFG#01

The TOTO Aurora Washlet+ S2 is a one-piece, completely skirted toilet with an elongated bowl, supplied with the Washlet S2 bidet seat and flushing at 1.28 GPF on TOTO's INTEGRAVITY SYSTEM™.

The S2 covers the core Washlet cleansing and comfort functions — front and rear washing, a heated seat and a warm-air dryer — and is operated from an arm control panel on the side of the seat.

  • 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 9/16"
  • Included Washlet: Washlet S2
  • Controls: Arm control panel on the side of the seat

INTEGRAVITY SYSTEM™

TOTO's gravity-driven flush engine uses a dual-tank, dual-valve architecture that sequences the rim wash and the siphon jet. TOTO states it rinses the bowl 5× longer compared with conventional toilets.

Completely Skirted Washlet+ Design

The Aurora is a one-piece toilet with a completely skirted exterior. As a Washlet+ toilet it uses TOTO's concealed supply connection, so no pipes or cords show between toilet and seat.

CEFIONTECT® and PREMIST®

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

Instantaneous Warm-Water Cleansing

Front and rear washing with oscillating and pulsating modes, and adjustable spray position, water temperature and water pressure. Water is heated instantaneously rather than stored warm.

Heated Seat and Warm-Air Dryer

The seat is heated and its temperature is adjustable. The warm-air dryer has three settings, the count TOTO gives the S2 and the S5.

Arm Control Panel

The S2 is operated from a convenient arm control panel on the side of the seat, so every function is adjusted at the seat itself.

TOTO Aurora WASHLET+ S2 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

  1. Prep. Shut off the water supply, flush to empty the tank, then disconnect the supply line.
  2. Remove the old toilet. Unbolt from the floor and scrape the old wax ring from the flange.
  3. Set the wax ring. Place a new wax ring on the flange, centered over the drain.
  4. Seat the new toilet. Lower onto the flange, press down firmly, and hand-tighten the bolts evenly.
  5. Connect and test. Reconnect the supply line, restore water, and plug into the GFCI outlet.

Frequently Asked Questions about TOTO Aurora S2

Does the WASHLET S2 come with a remote control?

No. The WASHLET S2 is operated from a control panel mounted on the right arm of the seat. If you would prefer a wireless remote with memory for up to four users, that is the WASHLET S5, which is otherwise the same seat.

Is the WASHLET S2 missing features the other WASHLETs have?

Less than most comparison charts suggest. The S2 includes instant warm water, PREMIST, EWATER+ wand cleaning, an automatic deodorizer, a heated seat, a three-setting warm air dryer and a night light. What it genuinely lacks against the S5 is the wireless remote and the seamless seat body.

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+ S2?

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.

TOTO Aurora WASHLET+ S2 One-Piece Toilet - 1.28 GPF

What Makes the TOTO Aurora One-Piece Design Different?

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

It uses what TOTO calls a completely skirted design, for a sleek and understated look that's easier to clean.

As a Washlet+ toilet it also uses TOTO's concealed supply connection, so no pipes or cords show between the toilet and the seat.

A 12-inch rough-in is standard, with 10-inch and 14-inch options available at additional cost.

  • One-piece Aurora design, elongated bowl
  • Completely skirted design, easier to clean
  • Concealed Washlet+ supply connection

What Makes the Aurora's INTEGRAVITY Flush Different?

The Aurora uses TOTO's INTEGRAVITY SYSTEM™, a gravity-driven flush engine TOTO states is exclusive to the Aurora.

Its 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, at 1.28 GPF.

The water is delivered through TORNADO FLUSH®, where two nozzles create a centrifugal, cyclonic rinsing action across a hole-free rim.

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

  • Dual-tank, dual-valve flush architecture
  • Sequenced rim wash and siphon jet
  • TORNADO FLUSH® across a hole-free rim

What Does the Washlet S2 Add?

The Washlet S2 washes front and rear, with oscillating and pulsating modes.

Spray position, water temperature and water pressure are adjustable, and the water is heated instantaneously rather than stored warm.

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

Every function is operated from a convenient arm control panel on the side of the seat.

EWATER+® keeps the wand hygienic, the wand cleans itself after every use, and the seat has an automatic air deodorizer.

  • Heated seat, three warm-air dryer settings
  • EWATER+® keeps the wand hygienic
  • Arm control panel on the seat

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+ S2?

The TOTO Aurora Washlet+ S2 is sold as a single combination SKU, MW6863346CEFG#01, pairing the Aurora one-piece toilet with the Washlet S2 in Cotton.

It flushes at 1.28 GPF on a standard 12-inch rough-in, with 10-inch and 14-inch rough-ins available at additional cost.

This is the Aurora configuration for a buyer who wants the core Washlet functions with arm-mounted controls.
