TOTO TCU436CRU#01 – Frequently Asked Questions
1) Is TOTO TCU436CRU#01 just the tank lid, or does it include the tank?
It's the vitreous china tank lid only. No tank, no trip lever, no flush valve or fill valve components come with it. Order it when the original lid is cracked or chipped and the tank itself is still good.
2) Which TOTO toilet does the TCU436CRU#01 china lid fit?
This lid is the replacement for the TOTO ST436U tank. TOTO tank lids are model specific, so confirm the number stamped or printed on the underside of your existing lid, or the tank model marked inside the tank, matches before ordering. A lid from a different TOTO tank series will not seat correctly.
3) My property has a mix of TOTO toilets. Can I stock one lid to cover all of them?
No. Tank lids are matched to the tank model, and TCU436CRU#01 fits the ST436U tank only. For a mixed fleet you need to identify each tank model and order the matching lid part number for each one. Only openings with the ST436U tank take this lid.
4) What is the TCU436CRU#01 lid made of, and will it match the rest of my toilet?
Vitreous china, the same material as the toilet body, so the surface and sheen match the tank it sits on. The #01 suffix at the end of the part number is TOTO's color code, and it has to match the color code on the toilet you are repairing, which appears after the # on the toilet's own model number.
5) Do I need a plumber to replace a TOTO toilet tank lid?
No. The lid sits loose on top of the tank, so it lifts off and the new one drops in place with no tools, no plumbing connections and no shutting off the supply. Handle it carefully, china chips on a hard edge.
