The TOTO WASHLET+ Aquia IV Cube Two-Piece Elongated Dual Flush 1.28 and 0.9 GPF Toilet and WASHLET C2 Bidet Seat is designed to conceal the WASHLET power cord and water supply hose for a seamless installation. Part of the newly redesigned C Series, the WASHLET C2 features a soft rear spray, rear cleanse, and front cleanse with the option of an oscillating stream. The temperature and pressure of the water are adjustable with three temperature settings and five pressure settings. The controls are located on a convenient arm control panel. PREMIST wets the surface of the toilet bowl, aiding in the removal of waste and resulting in a better clean. The C2 model utilizes TOTO's EWATER+ system when the wand self-cleans. EWATER+ transforms the water into a safe and powerful compound, creating peace of mind by cleaning the inside and outside of the wand before and after every use. The WASHLET features a heated SoftClose seat with three temperature settings. The Aquia IV Cube features TOTO's DYNAMAX TORNADO FLUSH, utilizing a 360 degree cleaning power to reach every part of the bowl. This version of the Aquia IV includes CEFIONTECT, a layer of ceramic glaze that minimizes waste from sticking to ceramic surfaces. This feature, coupled with the WASHLET PREMIST and TORNADO FLUSH, assists to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The enhanced design of the Aquia IV inner bowl reduces water flow resistance and turbulence, resulting in a quieter flush. Allows you to proactively conserve water by choosing between a 0.9 GPF rinse or 1.28 GPF for tougher jobs. The sleek tank design coupled with the skirted bowl create a sophisticated look and minimizes the need to reach behind the bowl to clean in between the nooks and crannies of the exterior trapway. Designed in TOTO's Universal Height, which allows for a more comfortable seat position across a wide range of users. The Aquia IV Cube comes ready for install into a 12" rough-in, but may be adapted for a 10" or 14" rough-in with the purchase of a separately sold adapter. Additional items needed for installation must be purchased separately: wax ring, toilet mounting bolts, and toilet water supply lines. Compatible with T40 WASHLET+ electronic bidet seat and toilet bowl components only.

TOTO MW4363074CEMFGN#01 – Frequently Asked Questions

1) What do I still need to buy to install a TOTO Aquia IV WASHLET+ toilet?
Plan on a wax ring, toilet mounting bolts, and a water supply line. Those three are not in the carton. What does come with it: the WASHLET installation hardware, the tank to bowl gasket, the tank to bowl hardware, and the toilet bolt caps. You also need a grounded electrical outlet within reach of the concealed cord location, since the WASHLET seat is powered.
2) Can I put a different brand of bidet seat on the Aquia IV WASHLET+ bowl?
No. The WASHLET+ version of the Aquia IV bowl is drilled and channeled to hide the seat's power cord and water supply hose, and it is compatible with T40 WASHLET+ electronic bidet seats and TOTO toilet bowl components only. A standard aftermarket bidet seat will not route through the concealed path and will leave the cord and hose exposed. If you want a non-TOTO seat, buy a conventional Aquia IV bowl instead of the WASHLET+ package.
3) What is the difference between the C2 and C5 WASHLET on the Aquia IV?
Both are T40 WASHLET+ seats and both give you front and rear warm water washing with three temperature settings and five pressure settings, an oscillating stream, PREMIST, a heated SoftClose seat, warm air dryer and air deodorizer, all run from an arm control panel. The C2 uses TOTO's EWATER+ to clean the wand inside and out before and after use. Every bowl configuration here, one-piece or two-piece, ADA or standard, is offered with either seat, so pick the seat feature set first and the bowl second.
4) How much water does the Aquia IV WASHLET+ toilet use per flush?
It is dual flush: 0.9 gallons for a light rinse and 1.28 gallons for solids, using TOTO's DYNAMAX TORNADO FLUSH. It is WaterSense certified and the description states CALGreen and CEC compliance, which is what you need if you are specifying into California multi-family or state funded work.
5) Should I order the one-piece or two-piece Aquia IV WASHLET+?
Both are floor mount with a floor outlet and both take the same 12 inch rough-in. The two-piece ships as tank and bowl with the tank to bowl gasket and hardware included, which makes it easier to carry up stairs and through tight doorways. The one-piece MW6463074CEMFGN#01 is a single vitreous piece at roughly 118 pounds shipping and 28-3/8 inches tall, versus a two-piece like MW4463074CEMFGN#01 at about 30-3/4 inches tall. If a low vanity backsplash or a window sill sits behind the toilet, check that height difference first.
6) Is the flush a push button or a lever, and which side is the lever on?
Both are offered. Push button models put the dual flush control on the tank top, and the side lever models mount the trip lever on the left side of the tank. Left hand levers matter when the toilet sits tight against a wall on that side, so check the wall it backs up to before you pick. ADA configurations are offered with either control type.
7) How hard is the Aquia IV WASHLET+ to keep clean in a high traffic unit?
Three things work together on it. CEFIONTECT ceramic glaze keeps waste from sticking to the bowl surface, PREMIST wets the bowl before each use, and the TORNADO FLUSH scrubs 360 degrees. The bowl is skirted, so there is no exposed exterior trapway to reach behind and wipe down. For property managers running a lot of units, that is less scrubbing time and less chemical per turn.
8) What are the component part numbers that make up the Aquia IV WASHLET+ package?
A representative Aquia IV WASHLET+ build ships as four pieces: bowl CT446CEFGNT40#01, tank ST436EMNA#01, WASHLET seat SW3074T40#01, and connection kit 9AU321-A. Those are the numbers to quote if you are ordering a replacement tank or seat down the road rather than a whole new fixture.
9) What size trapway does the Aquia IV have, and is it a fully glazed trap?
The trapway measures 2-1/2 inches. The description notes the inner bowl is shaped to cut water flow resistance and turbulence, which is what makes this one quieter than a typical dual flush. It is a floor outlet fixture, so it sets on a standard closet flange.
10) What color does the Aquia IV WASHLET+ toilet come in?
Cotton White (#01) across every configuration, one-piece and two-piece, C2 and C5, ADA and standard. If you are standardizing a building or matching existing TOTO fixtures, #01 Cotton White is the only finish in this family.
11) Does the Aquia IV WASHLET+ come with batteries, and what type?
Yes, alkaline batteries are included for the remote. The seat itself runs on household power through the concealed cord, so the batteries are only for the wireless control, not the wash functions.
