TOTO TCU446CRE#11 – Frequently Asked Questions
1) Which Toto toilet tank does the TCU446CRE lid fit?
It is the china lid for the Toto ST446E tank. Tank lids are matched to one tank casting, so ordering by the tank model stamped inside your existing tank is the way to get the right part. If your tank is not an ST446E, this lid will not seat properly.
2) What is the exact part number I need to order for a Toto ST446E replacement tank lid?
Order TCU446CRE#11. The base part is TCU446CRE and the #11 suffix is Toto's Colonial White color code, so the full number with the suffix is what identifies the finish you receive.
3) Does the Toto TCU446CRE tank lid come in other colors besides #11?
The TCU446CRE lid is offered here in the #11 finish only. Toto color suffixes are not interchangeable between lid part numbers, so if your fixture is cotton white or another Toto color you need the matching suffix for that color rather than this one.
4) I manage apartments and a tenant cracked a toilet tank lid. Can I replace just the lid instead of the whole toilet?
Yes, if the tank is a Toto ST446E. A cracked or chipped lid is a standalone replacement, and swapping it is a drop-on job with no water shut off and no plumbing work. The lid is vitreous china, so match the tank model and the color suffix and the toilet goes back into service without touching the bowl or the trim.
5) Will a tank lid from a different Toto model work on my ST446E?
No. China tank lids are cast to the rim profile of one specific tank, so a lid from another Toto model will rock, overhang, or sit loose even when it looks close in size. For an ST446E tank, TCU446CRE is the lid that matches.
