TOTO TCU446CRU#51 – Frequently Asked Questions
1) I cracked a toilet tank lid in one of my units. Can I just buy the lid from Toto instead of a whole tank?
Yes, for an ST446E tank you can order the lid on its own. TCU446CRU#51 is the standalone china lid, which is the usual fix for a chipped or cracked lid where the tank body and internals are still good. Match the ST446 tank model first, since Toto lids are specific to the tank they were molded for.
2) What does the #51 at the end of TCU446CRU#51 mean?
On Toto part numbers the suffix after the # is the finish code, so TCU446CRU#51 is the ST446E lid in that one specific color. Toto lids are only interchangeable within the same color code, so order the suffix that matches the tank and bowl already installed.
3) Does this Toto lid include the flush handle or any tank hardware?
No. TCU446CRU#51 is the china lid alone. Trip lever, fill valve, flush valve, tank-to-bowl bolts and gasket all have to be ordered separately if the repair needs them. A tank lid simply rests on the tank rim, so no mounting hardware is involved.
4) Is the Toto TCU446CRU lid ceramic or plastic?
It is a china (vitreous ceramic) lid, the same material as the tank itself, not a molded plastic cover. That matters for commercial restrooms and multi-family units where lids take abuse, and it also means it will chip rather than flex if it is dropped during install.
