TOTO TCU446CRU#03 – Frequently Asked Questions
1) Which TOTO tank does the TCU446CRU china lid fit?
The TCU446CRU is the vitreous china tank lid made for the TOTO ST446 tank. It is a replacement lid only, so the tank body, trip lever and internal trim are not included. Match your tank model marking before ordering, since TOTO lids are not interchangeable between tank series.
2) My TOTO toilet tank lid cracked. Can I just buy the lid instead of a new tank?
Yes, for an ST446 tank. The TCU446CRU china lid is sold as a standalone replacement part, which is the usual fix for a chipped or cracked lid in a multi-family or hotel bathroom, no tank swap and no re-plumbing involved. Only the china lid itself ships.
3) Will a TOTO tank lid from another model work on an ST446 tank?
No. China tank lids are model-specific, and the TCU446CRU is cut for the ST446 tank opening. A lid from another TOTO tank will sit proud, rock, or foul the flush mechanism. Use the ST446 lid for an ST446 tank.
4) What does the #03 suffix mean on TOTO part number TCU446CRU#03?
On TOTO part numbers the digits after the # are the finish code, so TCU446CRU#03 is the TCU446CRU tank lid in TOTO's #03 color. To keep a toilet looking uniform, order the lid in the same finish code stamped on the tank or bowl you are matching.
5) Is the TOTO TCU446CRU lid ceramic or plastic?
It is vitreous china, the same material as the tank itself, which is why it matches the tank in color and gloss rather than yellowing like a plastic cover. Handle it as ceramic: set it flat, do not drop it on a tile floor, and avoid abrasive cleaners that dull the glaze.
