TOTO TCU453CRU#51 – Frequently Asked Questions
1) Which Toto tank does the TCU453CRU#51 lid fit?
It's the replacement china tank lid for the Toto ST453U toilet tank. Tank lids are tank-specific, so match the tank model stamped inside the tank or on the bowl before ordering, and order under part number TCU453CRU#51.
2) I manage a building with several Toto toilets and a cracked tank lid. Can I use a lid from a different Toto model?
No. A Toto tank lid is cut for one tank footprint, and the TCU453CRU#51 is made for the ST453U tank. A lid off another Toto tank will not seat correctly on the rim. Identify the tank model first, then order the lid that matches it.
3) Is the TCU453CRU#51 just the lid, or does it include tank trim?
Lid only. TCU453CRU#51 is the tank cover itself, no flush valve, fill valve, handle or tank-to-bowl hardware. If the trim inside the tank is what's failing, order those parts separately.
4) Does replacing a Toto tank lid require any tools or plumbing work?
None. The lid sits loose on the tank rim, so it lifts off and the new one drops on with no fasteners, no gaskets and no need to shut off the supply. That makes it a straightforward swap for maintenance staff on an occupied restroom.
