TOTO TCU453CRU#03 – Frequently Asked Questions
1) Which Toto toilet tank does the TCU453CRU#03 tank lid fit?
The TCU453CRU#03 is the replacement tank lid for the Toto ST453U tank. It is a lid only, so it is matched to that tank model and is not a universal fit for other Toto tanks.
2) My Toto tank lid cracked, can I order just the lid instead of a whole new toilet?
Yes. The TCU453CRU#03 is sold as a standalone tank lid, which is the usual repair when a lid is chipped or cracked but the tank and bowl are fine. It carries no flush valve, fill valve, or trip lever, so you are ordering the ceramic lid alone for an ST453U tank.
3) What does the #03 suffix mean on Toto part number TCU453CRU#03?
On Toto part numbers the digits after the hash are the finish code, and it has to match the toilet you are repairing or the lid will not blend with the tank. TCU453CRU#03 is the #03 finish version of the ST453U lid.
4) We standardize toilets across a building, can one Toto lid cover several tank models?
No. Toto tank lids are model specific, and TCU453CRU#03 is cut for the ST453U tank only. For a mixed fleet you need to pull the model number stamped inside each tank and order the matching lid for each one.
5) Does the Toto TCU453CRU#03 lid include the flush button or trip lever assembly?
It does not. The TCU453CRU#03 is the tank lid itself, a washroom accessory part for a toilet application. If your flush mechanism is also damaged, that trim is ordered separately.
