TOTO TCU446CRU#11 – Frequently Asked Questions
1) Which TOTO toilet tank does the TCU446CRU tank lid fit?
The TCU446CRU is the vitreous china tank lid made for the TOTO ST446 tank. It is a direct replacement part for that tank only, so if the tank on the toilet is not an ST446, this lid will not seat correctly. Check the model number stamped inside the tank before ordering.
2) I cracked a toilet tank lid in one of my units - can I buy just the lid instead of a whole toilet?
Yes. The TCU446CRU is sold as a standalone china tank lid for the TOTO ST446 tank, so a cracked or chipped lid can be replaced without touching the tank, bowl, or trim. No flush valve, trip lever, or fill valve comes with it; it is the lid alone.
3) What is the exact part number I should order for a TOTO ST446 tank lid in cotton white?
Order TCU446CRU#11. The #11 suffix is TOTO's color code that follows the base part number, and it is the only code this lid is offered under.
4) Does the TOTO TCU446CRU lid include a flush button or push-button trim?
No. TCU446CRU is the china lid by itself. Any trip lever, push button assembly, or tank-to-bowl hardware on the ST446 tank stays with the tank and is ordered separately if it also needs replacing.
5) Is a replacement china tank lid something an onsite maintenance tech can handle?
Yes, it just sets in place on the ST446 tank - no tools, no draining, no plumbing work. Handle it like any vitreous china piece: it chips on edges and corners, so set it flat rather than on its rim while working.
