TOTO TCU446CRU#01 – Frequently Asked Questions
1) Which TOTO tank does the TCU446CRU#01 china lid fit?
The TCU446CRU#01 is the vitreous china tank lid for the TOTO ST446U tank. If the tank on your toilet is stamped ST446U, this is the matching replacement lid. Lids are not interchangeable between TOTO tank models, so check the number molded inside the tank or on the back of the broken lid before ordering.
2) Is a TOTO china tank lid sold separately from the tank, or do I have to buy the whole tank?
This is a standalone replacement part, just the china lid itself. No tank, no trip lever, no flush valve or fill valve comes with it. For a cracked or chipped lid on an ST446U tank, replacing the lid alone is the fix, you do not need to pull the tank.
3) What does the #01 suffix mean on TOTO part number TCU446CRU#01?
On TOTO part numbers the digits after the hash are the color code, and #01 is Cotton White. Order the code that matches the rest of the toilet, since a lid in a different color code will not blend with the tank and bowl.
4) I manage apartments with TOTO toilets and lids keep getting cracked. Can I stock one lid for all of them?
Not unless every tank is the same model. A TOTO china lid is cut to one tank footprint, and the TCU446CRU#01 is specific to the ST446U tank. For a mixed fleet, inventory by tank number, record which unit has which tank, and order the lid that matches that tank rather than a single catch-all part.
5) Does this TOTO lid come with a trip lever or flush handle?
No. The TCU446CRU#01 is the china lid only. If the handle or trip lever is also damaged, that is a separate TOTO part keyed to the tank model, ordered on its own.
