TOTO TCU454CRE#51 – Frequently Asked Questions
1) Will the Toto TCU454CRE#51 tank lid fit a Toto ST454E tank?
Yes. The TCU454CRE#51 is the replacement tank lid made for the Toto ST454E tank, so it drops onto that tank without modification. Tank lids are tank-specific, so if the tank stamped inside your lid or on the china is anything other than ST454E, order the lid for that tank number instead.
2) I cracked the lid on a Toto toilet in one of my units. Do I have to replace the whole tank?
No. The tank lid is sold on its own as a service part, so a cracked or chipped lid on an ST454E tank is a lid-only replacement. The TCU454CRE#51 is the lid for that tank. Nothing inside the tank is affected, so the fill valve, flush valve and trip lever stay as they are.
3) How do I confirm which Toto tank lid I need before ordering?
Lift the existing lid and read the tank number molded inside the tank or on the back of the china. Toto tank lids are matched to that tank number, not to the complete toilet model, so an ST454E tank takes the TCU454CRE#51 lid. Also note the color code following the hash on the toilet so the replacement matches.
4) What does the #51 at the end of Toto TCU454CRE#51 mean?
On Toto part numbers the digits after the hash are the china color code, so TCU454CRE#51 is the ST454E lid in that one color variant. Match the color code on the lid to the toilet it sits on, since a lid in a different code will be a visible mismatch against the tank and bowl.
5) Does the Toto TCU454CRE#51 tank lid come with any flush hardware or trip lever?
It is the china lid only. No trip lever, no flush valve, no fill valve, no gasket set. If the handle broke along with the lid, the trip lever is a separate part ordered for the ST454E tank.
