TOTO UltraMax One-Piece Toilet with E-Max Flushing System

The TOTO UltraMax is a one-piece toilet engineered around TOTO's commitment to "People Planet Water." Available in elongated and round bowl configurations, standard and ADA-compliant heights, 1.28 GPF and 1.6 GPF flush volumes, and with or without CEFIONTECT ion-barrier glaze, this listing covers the full UltraMax family. Select your exact configuration using the options above.

The one-piece construction eliminates the tank-to-bowl joint found on two-piece toilets, removing the gap where dirt and debris accumulate and eliminating the risk of leaks from bolts or gaskets. Cleaning is faster and more reliable, a meaningful advantage in multi-unit residential, hospitality, and commercial restroom applications.

E-Max Flushing System

The E-Max system combines a 3-inch wide flush valve, an extra-large siphon jet, and a full-size 2.125-inch trapway to generate a powerful, quiet, clog-resistant flush. At 1.28 GPF, it meets EPA WaterSense, California CEC, and CALGreen requirements, qualifying for water-efficiency rebates in most jurisdictions. The 1.6 GPF option is available for projects where code or preference requires the higher flow rate.

CEFIONTECT Glaze (Optional)

Select variants include TOTO's CEFIONTECT ion-barrier glaze, an ultra-smooth ceramic surface that prevents waste, mold, and bacteria from adhering to the bowl. This reduces the frequency and intensity of cleaning required, lowering maintenance labor costs in high-traffic commercial and multi-family settings.

ADA-Compliant Height Option

ADA-compliant variants feature a 16.5625-inch rim height, meeting Americans with Disabilities Act requirements for accessible restroom installations. Standard-height variants have a 14.625-inch rim height. Confirm ADA compliance requirements for your project before selecting.

TOTO MS853113E#01 – Frequently Asked Questions

1) Will the TOTO UltraMax one-piece toilet fit my existing 12-inch rough-in?
Yes. Every UltraMax one-piece is built for a 12-inch rough-in, floor mount with a floor outlet, so it drops onto a standard closet flange set 12 inches off the finished wall. Overall length runs 26.5 to 28.25 inches depending on bowl shape and height, and width is 16.5 inches, so measure your clearance forward from the flange, not from the wall.
2) Which TOTO UltraMax do I order for an ADA-compliant restroom?
Order an ADA variant. Those sit at a 16.5625-inch rim height, which meets the ADA seat-height requirement for accessible stalls; the standard-height UltraMax sits at 14.625 inches and does not. The ADA models are the taller ones overall at 29.25 inches high versus 27.125, and 28.25 inches long, so an accessible stall that was laid out around a standard bowl needs the clearance rechecked.
3) Is the TOTO UltraMax WaterSense certified, and does it meet California CALGreen and CEC?
The 1.28 GPF UltraMax is EPA WaterSense certified and meets both California CEC and CALGreen requirements, which is what a California project or a water-rebate submittal needs. The 1.6 GPF version is there for jobs where code or an existing spec calls for the higher volume, but it is the 1.28 that carries the water-efficiency compliance.
4) Round or elongated bowl for a tight bathroom, and how much length does it save?
Round is the short one. The round-bowl UltraMax measures 26.5 inches long against 28 inches for the standard-height elongated, so you pick up about an inch and a half of floor in front of the bowl. In a powder room or a tight multi-family bath with a door swing or a vanity in the way, that is usually the deciding number. Elongated gives the more comfortable seat and is the normal choice in hospitality and commercial restrooms where the clearance exists.
5) I have a 1.6 gallon toilet now. Can I put a 1.28 GPF UltraMax on the same drain line?
Same rough-in, same floor outlet, so mechanically it is a straight swap onto a 12-inch flange. The thing to check first is the drain slope on your building's waste line: older long horizontal runs sized around 3.5 and 1.6 gallon flushes carry less water with a 1.28, and if you are converting a whole stack at once that is the conversation to have with the plumbing engineer. Where that is a concern, the UltraMax is also built in 1.6 GPF with the same body and the same 2.125-inch trapway, so you keep the fixture and drop back to the higher volume.
6) Does a one-piece toilet like the TOTO UltraMax really clean up easier than a two-piece?
That is the practical reason to spend up on it. There is no tank-to-bowl joint, so there is no seam collecting dirt behind the bowl and no tank bolts or gasket to weep years later. For a property manager turning units or a housekeeping crew doing a floor of guest baths, it is fewer minutes per fixture and one less leak call. If you want it to stay clean with less scrubbing, take the CEFIONTECT glaze option, which is an ion-barrier ceramic surface that keeps waste and mold from sticking.
7) Will the TOTO UltraMax clog with the low 1.28 gallon flush?
The E-Max system is built around volume of water moving fast rather than a lot of it. A 3-inch flush valve dumps the tank quickly, a large siphon jet starts the siphon, and a full 2.125-inch trapway carries it out. That 2.125-inch trapway is the number that matters for clog resistance, and it is the same on the 1.28 and the 1.6 GPF models.
8) Can I get the TOTO UltraMax with the trip lever on the right side?
Both. The chrome trip lever is offered in left-hand and right-hand, chosen at order time. It matters when the toilet sits in an alcove or hard against a vanity and the lever would otherwise land against the wall, and it matters for accessible stalls where the flush control has to be on the open side of the fixture.
9) Do I need to buy a seat separately for the TOTO UltraMax?
No, a SoftClose seat ships with it. That is worth knowing on a bulk order, since a competing two-piece often quotes bare and the seat is a separate line. The lid will not slam, which is the usual complaint in apartments and hotels with shared walls.
10) Is the CEFIONTECT glaze on the TOTO UltraMax worth it for a high-traffic restroom?
In a building where a crew cleans the same fixtures every day, yes. CEFIONTECT is an ultra-smooth ion-barrier ceramic surface that stops waste, mold, and bacteria from adhering, so bowls need less frequent and less aggressive cleaning, which is labor cost in a hotel or a large multi-family property. In a single-family bath flushed a few times a day, the plain glaze is the cheaper spec and holds up fine. Note the glazed models are offered in Cotton White.
11) What colors does the TOTO UltraMax come in for matching the rest of a building's fixtures?
Four: Cotton White, Bone, Colonial White, and Sedona Beige. If you are standardizing across a portfolio, Cotton White is the one carried across the widest set of configurations, including the CEFIONTECT-glazed and ADA models. Bone, Colonial White, and Sedona Beige appear on the standard and ADA models without the glaze option.
12) How heavy is the TOTO UltraMax, and is it a one-man set?
Between 91 and 99 pounds depending on model, with the round-bowl coming in at 91 and the taller ADA and glazed models at the top of that range. One-piece toilets carry all that weight in a single awkward unit rather than splitting into a tank and a bowl, so plan on two people to set it and to get it up a stair. Worth building into the labor line on a multi-unit replacement.
13) Does the TOTO UltraMax need power or batteries?
No power and no batteries. The UltraMax is a straight gravity flush with a manual trip lever, so there is nothing to wire and no cells to change on a maintenance schedule. That keeps it usable in an existing restroom with no receptacle behind the fixture.
