TOTO TCU646CRU#12 – Frequently Asked Questions
1) Which toilet does the TOTO TCU646CRU#12 china tank lid fit?
It is the replacement china tank lid for the TOTO CST646U toilet. Tank lids are model-specific china castings, so it is intended for that tank and not as a universal fit across other TOTO models.
2) Is this just the lid, or does it include tank internals or a trip lever?
Lid only. TCU646CRU#12 is the vitreous china cover that sits on the tank, with no flush valve, fill valve, trip lever or gasket included. If the fill or flush hardware is also failing, order those separately.
3) My property has several TOTO toilets and one cracked lid. Can I order a single lid instead of a whole toilet?
Yes, that is exactly what this part is for. A cracked or chipped tank lid on a CST646U can be replaced on its own with TCU646CRU#12, no need to pull the toilet or buy a new tank. Confirm the tank you are matching is a CST646U, since china lids do not interchange between TOTO model families.
4) What does the #12 at the end of TCU646CRU#12 mean?
The suffix after the hash is TOTO's color code, so TCU646CRU#12 is that lid in the #12 china color. Match the suffix on the lid to the color code on the existing tank, or the replacement will be the right shape in the wrong shade.
