TOTO TCU453CRU#11 – Frequently Asked Questions
1) Which Toto toilet tank does the TCU453CRU#11 lid fit?
It's the replacement tank lid for the Toto ST453U tank. Tank lids are tank-specific, so match the lid to the ST453U casting and not just to the bowl model or the overall toilet suite name. If the tank stamped inside your unit is anything other than ST453U, this lid is the wrong part.
2) What part number should I order for a Toto ST453U replacement tank lid, and is a tank included?
Order TCU453CRU#11. That's the lid only, a single china cover for the ST453U tank. No tank, no trip lever, no flush valve or fill valve comes with it, so if the tank body itself is cracked you need the complete tank rather than this cover.
3) I manage apartments and a tenant broke a toilet tank cover. Can I just buy the lid instead of a whole toilet?
Yes, for a Toto ST453U tank that's exactly what this part is for. The TCU453CRU#11 is the factory lid sold on its own, so a dropped or cracked cover doesn't mean replacing the fixture. Check the model stamped inside the tank before ordering, since Toto lids don't interchange between tank models.
4) Does a Toto tank lid need any mounting hardware or tools to install?
No hardware. A china tank cover like the TCU453CRU#11 simply sets onto the rim of the ST453U tank under its own weight, so installation is lift off the broken one and set the new one in place. Nothing to bolt, no gasket, no plumbing to break into.
