The TOTO Ultimate One-Piece Round Bowl 1.6 GPF Toilet projects TOTO's mark of excellence: "People Planet Water." The TOTO Ultimate features a sleek, one-piece design that will immediately beautify the appearance of your bathroom. The one-piece design is not only aesthetically pleasing, but also offers the benefit of being easier to clean versus a two-piece toilet. By removing the gap between the tank and bowl, we eliminate the hiding place for dirt and debris. An additional benefit of the one-piece toilet is that there is no threat of leaks from bolts or gaskets that can occur in two-piece toilets. The TOTO Ultimate features TOTO's innovative Power Gravity flushing system that enables the toilet to perform powerful flushes. The TOTO Ultimate includes a TOTO SoftClose seat and a left-hand side chrome lever.

TOTO MS853113#01 – Frequently Asked Questions
1) How tall is the seat on the TOTO Ultimate, and is it a comfort height toilet?
Rim height on the Ultimate is 14.625 inches, which is a standard height bowl, not a comfort or right height fixture. Add roughly a half inch of seat on top of that. If you are specifying for senior housing, an accessible unit, or anywhere you want a taller seat around 16-1/2 to 17 inches, this is the wrong model and you want a comfort height one-piece instead. Overall height to the top of the tank is 27.125 inches, so it clears a window sill or a low vanity backsplash easily.
2) Does the TOTO Ultimate come with a seat, or do I have to buy one separately?
A TOTO SoftClose seat is included in the box, along with a left-hand chrome trip lever already fitted. So the only things you are adding to the order are a wax ring or waxless seal, closet bolts, and a supply line. For a property manager doing a run of unit turns, that is one less line item to track per bathroom.
3) Can I use the TOTO Ultimate to replace a standard two-piece toilet already in the bathroom?
In most cases yes, because the Ultimate uses the same 12 inch rough-in and floor outlet mounting that a standard two-piece uses. Pull the old fixture, check that the flange measures 12 inches from the finished wall to its center and that it sits at or slightly above finished floor, then set the new bowl on a fresh wax ring and new closet bolts. Two things to plan for: the one-piece body is 91 to 93 pounds and needs two people to set, and the supply stop needs to line up with a left-hand lever layout.
4) Which side is the flush handle on the TOTO Ultimate?
Left-hand side, in chrome. On a one-piece tank that is not something you swap easily the way you would on a two-piece, so check your clearance before ordering. If the toilet tucks into an alcove or sits tight against a side wall on the left, the lever is the thing that gets blocked.
5) What colors does the TOTO Ultimate come in?
Four colors across both bowl shapes: Cotton White, Colonial White, Bone, and Sedona Beige. Every color is offered in both the round bowl and the elongated bowl, so you can match an existing fixture run without being forced into one shape. Colonial White and Cotton White are distinct shades, not the same white, which matters if you are adding a toilet to a bathroom where the tub and lav are already TOTO in one of them.
6) How do I read the TOTO Ultimate part number to order the right color?
The base number gives you the bowl shape and the suffix after the hash gives you the color. MS853113 is the round bowl, MS854114 is elongated. Then #01 is Cotton White, #03 is Bone, #11 is Colonial White, and #12 is Sedona Beige. So MS854114#12 is the elongated bowl in Sedona Beige. Getting the suffix wrong is the most common way a replacement lands on site in the wrong shade.
7) Is a one-piece toilet like the TOTO Ultimate worth it over a two-piece for a rental or multi-family unit?
The case for one-piece in rental stock is maintenance, not looks. There is no tank-to-bowl gasket or bolt set between tank and bowl, so the single most common slow leak call on a two-piece toilet does not exist here. Cleaning is faster too, since there is no seam behind the tank collecting grime between turns. The tradeoff is weight and handling: the round bowl unit is 91 pounds and the elongated is 93 pounds in one piece, so it is a two-person carry up stairs, and if the china cracks you replace the whole fixture rather than a tank.
8) Does the TOTO Ultimate need power or batteries?
No power and no batteries. The Ultimate is a straight gravity flush fixture, all mechanical, with a manual left-hand trip lever. Nothing to wire, no receptacle needed behind the fixture, and no battery to replace on a maintenance schedule. That separates it from washlet-equipped and sensor-flush models that do require a GFCI outlet nearby.
