The TOTO T40 WASHLET+ Carlyle II One-Piece Elongated 1.28 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 Carlyle II toilet features TOTO's TORNADO FLUSH, a hole-free rim design with dual-nozzles that creates a centrifugal washing action that assists in rinsing the bowl more efficiently. This version of the TOTO Carlyle II 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 TOTO Carlyle II is designed in TOTO's Universal Height, which allows for a more comfortable seat position across a wide range of users. This WASHLET+ includes the WASHLET with water supply adapter, Carlyle II bowl and tank set with hardware, and toilet bolt caps. Compatible with T40 WASHLET+ electronic bidet seat and toilet bowl components only. Additional items needed for installation must be purchased separately: wax ring, toilet mounting bolts, and toilet water supply lines.

TOTO MW6143074CEFG#01 – Frequently Asked Questions
1) What rough-in does the TOTO Carlyle II WASHLET+ toilet require, and can it work on a 10 or 14 inch rough-in?
The Carlyle II is built for a standard 12 inch rough-in, measured from the finished wall to the center of the closet flange. If the drain in your floor sits at 10 or 14 inches, it can still be used with an optional adapter: TSU01W.10R for a 10 inch rough-in or TSU01W.14R for 14 inch. Those adapters ship separately, so add one to the order before the plumber gets on site. Measure the existing rough-in before you commit, because a skirted one-piece bowl gives you no room to fudge the setting.
2) Is the TOTO Carlyle II toilet ADA compliant and comfort height?
Yes, the Carlyle II is ADA compliant and built in TOTO's Universal Height. Seat height is 17.5 inches and rim height is 16.125 inches, which puts the finished seat in the comfort-height band a facility needs for accessible stalls and for older residents. That matters for anyone standardizing on one model across a multi-family building or a healthcare wing. It is also WaterSense labeled and meets CALGreen and CEC requirements, which is what a California job or a green-build spec will ask for.
3) What is the difference between the Carlyle II C2 and C5 WASHLET, and what does the Connection Only version include?
Three configurations are sold. Connection Only is the Carlyle II bowl and tank prepped for a WASHLET+ seat, without the seat, so you buy it when the bidet seat is being sourced separately or added later. The C2 adds the C Series bidet seat with front and rear cleanse, oscillating stream, three water temperature settings, five pressure settings, EWATER+ wand self-cleaning, PREMIST, a heated SoftClose seat, deodorizer and warm air dryer, all on an arm control panel. The C5 is the higher seat in the same family. All three are ordered in Cotton White.
4) What else do I need to buy to install a TOTO Carlyle II toilet?
The carton covers the WASHLET with water supply adapter, the Carlyle II bowl and tank set, tank-to-bowl gasket and hardware, WASHLET installation hardware, and the bolt caps. You still have to supply the wax ring, the toilet mounting bolts, and the water supply line. Add an adapter (TSU01W.10R or TSU01W.14R) if the rough-in is not 12 inches. Batteries come with it, alkaline type, for the remote.
5) Will a standard bidet seat or aftermarket washlet fit the Carlyle II bowl?
No. The Carlyle II WASHLET+ bowl is cut for T40 WASHLET+ electronic bidet seats and T40 toilet bowl components only. A generic bidet seat or a non-WASHLET+ TOTO seat will not mate with the concealed cord and supply routing that makes this bowl what it is. If you want an aftermarket seat, buy a conventional TOTO bowl instead, not the WASHLET+ version.
6) Is the Carlyle II floor mounted with a floor outlet, and what is the trapway size?
Floor mount, floor outlet. It sets on a standard closet flange in the slab or subfloor with a wax ring, so it is not a wall-hung or rear-discharge fixture and it will not adapt to a back-outlet stack. The trapway is 2-1/8 inches. If your building runs rear discharge waste, this is the wrong fixture and you need a wall-outlet model.
7) How much space does the TOTO Carlyle II need, and how heavy is it to set?
Plan on roughly 28-5/16 inches of length off the wall and about 18-9/16 inches of width, with an overall height near 28.75 inches. It is an elongated skirted bowl, so check the clearance to a vanity or a swinging door before you commit; elongated adds a couple inches of projection over round front. Shipping weight runs around 127 pounds for the WASHLET versions, which makes it a two-person set on any floor.
8) Why do some Carlyle II models list 1.0 GPF and others 1.28 GPF?
Both flush rates are offered across the range. The 1.28 gallon per flush version is the WaterSense standard and the one most jurisdictions and rebate programs are written around. The 1.0 GPF version, ordered as the CUFG models, moves less water per flush for a project chasing a tighter water budget. Either way you get the same TORNADO FLUSH hole-free rim with dual nozzles and a 3 inch flush valve, which is what keeps the bowl rinsing at those volumes.
9) What are the component part numbers for the TOTO Carlyle II WASHLET+ set?
The C2 configuration breaks down into two components: the bowl and tank set CST614CEFGAT40#01 and the WASHLET seat SW3074T40#01. Those are the numbers to quote if a service call needs only one half of the assembly replaced, or if a facility is stocking spares. Complete assemblies are ordered under the MW and MS numbers, for example MW6143074CEFG#01 for the 1.28 GPF C2 in Cotton White.
10) Which side is the flush lever on the TOTO Carlyle II, and does it matter in a tight bathroom?
Left side, facing the toilet. In a narrow water closet or a corner install where a vanity or wall crowds the tank on the left, that can put the lever hard against an obstruction. Check the clearance on the left of the tank before setting it, particularly in a multi-family retrofit where the compartment was framed for an older fixture.
11) Does the CEFIONTECT glaze on the Carlyle II actually cut cleaning time in a high traffic restroom?
CEFIONTECT is a ceramic glaze layer that keeps waste from clinging to the bowl surface. Paired with PREMIST, which wets the bowl before use, and the TORNADO FLUSH centrifugal rinse, it reduces how often the bowl needs scrubbing and how much chemical goes into it. For a property manager running janitorial across many units, that is the practical argument for the CEFG models over a plain glazed bowl. Note the CUFG variants are the non-CEFIONTECT designation in the same range.
