TOTO CST404CUFRG#01 – Frequently Asked Questions
1) Is the Promenade II toilet ADA compliant, and how tall is the seating height?
ADA compliant, yes. The Promenade II uses TOTO's Universal Height design, with a rim height of 16.25 inches before you add a seat. That puts the finished seat height in the comfort-height range once a seat is mounted, which is what an ADA opening calls for. For a hospitality or healthcare facility standardizing on one fixture, this is the elongated Universal Height model to spec.
2) What do I need to buy on top of the Promenade II toilet to actually install it?
The Promenade II ships as a bowl and tank set with the tank-to-bowl gasket, tank-to-bowl hardware, and toilet bolt caps in the carton. You still have to supply the wax ring, the toilet mounting bolts (closet bolts), the water supply line, and the toilet seat. Budget those four line items on every unit if you are ordering for a multi-unit rollout, because none of them come in the box.
3) Should I get the 1.0 GPF or the 1.28 GPF Promenade II?
Both flush volumes are offered. The 1.28 GPF version is the standard WaterSense volume and is the safer choice on older drain lines or long horizontal runs where carry matters. The 1.0 GPF version uses TOTO's 1G technology to complete the flush on a single gallon, which is what you want when a water utility rebate, CALGreen, or California CEC compliance is driving the spec. Either way the bowl uses TORNADO FLUSH, a hole-free rim with dual nozzles.
4) How much space do I need for a Promenade II toilet in a small bathroom?
The complete two-piece Promenade II measures 28.5 x 17.75 x 31.25 inches. The bowl is elongated, so it projects further off the wall than a round-front would. In a tight powder room or a multi-family bath with a door swing close to the fixture, measure that 28.5 inch dimension against your clear floor space before ordering. A bowl-only configuration is also offered if you are replacing just the bowl and keeping an existing tank.
5) Does the Promenade II meet California water efficiency requirements?
Yes on all three: the Promenade II is EPA WaterSense listed and meets California CEC and CALGreen requirements. That combination is what a California institutional or municipal spec normally asks for, and it is also what most utility rebate programs key off. It is ADA compliant as well, so one model covers both the water and the accessibility line on the submittal.
6) Can I get a Promenade II with the flush lever on the left side?
Both lever hands are available. The lever is offered in left and right, so if the toilet sits in an alcove or against a vanity where one side is blocked, order the hand that clears. The decorative trip lever is chrome. Pick the hand at order time; it is a configuration choice, not something you reverse on site.
7) What colors does the TOTO Promenade II come in besides white?
Five finishes: Cotton White, Colonial White, Bone, Sedona Beige, and Ebony. Cotton White and Colonial White are two distinct whites, so if you are matching an existing TOTO fixture in a building, confirm which white the original was rather than assuming. Bone and Sedona Beige are the warmer tones common in older multi-family bathrooms.
8) Is CEFIONTECT glaze worth ordering on a Promenade II for a high-traffic restroom?
CEFIONTECT is available or omitted, so it is a decision at order time. It is a ceramic glaze layer that keeps waste from adhering to the bowl surface. Paired with the TORNADO FLUSH rinse, it cuts how often the bowl needs scrubbing and how much chemical the cleaning crew uses. On a building where housekeeping labor is the recurring cost, that is the version to spec. On a low-use residential unit the non-glazed version flushes identically.
9) What are the bowl and tank part numbers if I only need to replace one half of a Promenade II?
The two-piece set breaks into a C404CUFG bowl and an ST403UR tank. If a bowl cracks and the tank is fine, order the bowl on its own rather than a complete set. A bowl-only configuration is offered for exactly that case. Match the finish code and the glaze option to what is already installed, or the two halves will not match in color.
10) How big is the trapway and flush valve on the Promenade II?
The trapway measures 2-1/8 inches in diameter and the tank uses a 3 inch flush valve. The large flush valve is what dumps the tank fast enough for a 1.0 or 1.28 gallon flush to clear the bowl. When you are stocking repair parts across a portfolio, the 3 inch valve size is the number to match on replacement flappers and seals.
11) How heavy is a Promenade II toilet, and is it a one-person set?
The complete two-piece Promenade II weighs 91.5 pounds. Split into its bowl and tank halves it handles fine for one installer, which is part of why a two-piece is easier to carry up stairs and through a finished unit than a one-piece of the same size. Plan the lift accordingly on upper-floor multi-family work.
