TOTO TCU646CRU#11 – Frequently Asked Questions
1) Which Toto toilet does the TCU646CRU#11 tank lid fit?
The TCU646CRU#11 is the vitreous china tank lid made for the Toto CST646U toilet. It is a model-specific replacement lid, so it should be ordered by matching the tank model, not by measuring an existing lid.
2) I cracked a toilet tank lid in one of my units - can I just order a lid instead of a whole toilet?
Yes. The TCU646CRU#11 is sold as a standalone china tank lid for the CST646U, so a cracked or chipped lid can be replaced without touching the tank, bowl, or trim. It is just the lid itself, with no flush handle, fill valve, or flapper included.
3) Will a Toto tank lid from a different model fit my CST646U?
No. Toto china lids are cut to the specific tank they ship on, and the TCU646CRU#11 is the lid matched to the CST646U. A lid from another Toto tank will typically sit proud or rock on the tank rim. Identify the tank by its model number and order the lid that carries that model's lid number.
4) What does the #11 suffix on TCU646CRU#11 mean?
On Toto part numbers the suffix after the hash is the finish code, and #11 is Toto's Colonial White china. If the rest of the fixture is Cotton (#01) or another color, the lid will not match, so confirm the color code stamped inside the existing lid before ordering.
5) Is any hardware or sealing needed to install this Toto china tank lid?
No fasteners are involved. A Toto china tank lid rests on the tank rim under its own weight, so installation is simply setting it in place and checking it sits flat with no rock. Since it is unsecured china, handle it off the tank when working on the fill valve or flapper.
