TOTO TCU776CR#51 – Frequently Asked Questions
1) Which Toto toilet does the TCU776CR#51 tank lid fit?
It's the replacement tank lid assembly for the Toto ST776 tank. Tank lids are model-specific, so match it to an ST776 tank body; it won't seat correctly on other Toto tanks.
2) I manage a building with several Toto toilets and one lid got cracked. How do I make sure I order the right one?
Find the model number stamped inside the tank or on the back of the tank wall. If the tank reads ST776, the TCU776CR#51 lid assembly is the matching replacement. If it reads anything else, you need that tank's own lid - Toto lids are not interchangeable across tank models, and a near-match will rock or leave a gap at the tank rim.
3) Is TCU776CR#51 just the lid, or does it include tank trim?
It's the tank lid assembly for the ST776 only. Flush valve, fill valve, and other tank internals are separate parts and would need to be ordered on their own.
4) Does the TCU776CR#51 tank lid come in more than one color?
It's supplied in the single #51 finish code. Toto uses the suffix after the hash to denote color, so if your fixture is a different Toto color, you'd order the ST776 lid in that color code instead.
5) Is this a toilet tank lid or a urinal/bidet part?
Toilet. The TCU776CR#51 is a toilet tank lid assembly, sized for the ST776 tank.
