TOTO TCU646CRE#11 – Frequently Asked Questions
1) Which TOTO toilet does the TCU646CRE#11 china tank lid fit?
The TCU646CRE#11 is the vitreous china tank lid made for the TOTO CST646E toilet tank. It is a direct replacement part for that model, so it is the right lid if the broken one came off a CST646E. It is not a universal lid; tank lids are model specific and will not seat correctly on another TOTO tank.
2) Is TCU646CRE#11 just the lid, or does it come with tank trim or a flush valve?
Lid only. TCU646CRE#11 is the china tank cover for the CST646E and includes no fill valve, flush valve, flapper, trip lever or gasket. If the tank internals are also failing, order those separately as TOTO repair parts for the CST646E.
3) I cracked a toilet tank lid in one of my units - can I just buy the lid instead of a whole new toilet?
Yes, for a CST646E you can replace just the cover. TCU646CRE#11 is sold as the standalone china lid, which is the usual repair when the tank and bowl are intact and only the cover is chipped or cracked. For property managers running multiples of the same toilet, keeping one spare lid on the shelf avoids pulling a whole fixture.
4) What does the #11 at the end of TOTO TCU646CRE#11 mean?
The suffix after the hash on a TOTO part number is the finish code, and #11 is TOTO's Colonial White. Order the lid in the same code as the toilet it sits on, since the lid is the visible top of the tank and a mismatched code will read as an off-white against a cotton white fixture.
5) Does a replacement china toilet tank lid need any hardware or sealant to install?
No fasteners are involved. A china tank lid like TCU646CRE#11 simply sets onto the rim of the CST646E tank under its own weight, so installation is lifting the old cover off and setting the new one on. Handle it with two hands; vitreous china chips at the edges if it is dropped onto the tank rim.
