TOTO TCU776CR#01 – Frequently Asked Questions
1) Is the Toto TCU776CR#01 tank lid a genuine Toto replacement part for the ST776 tank?
It's the factory Toto tank lid assembly for the ST776 tank, ordered under part number TCU776CR#01. Toto tank lids are model-specific castings, so the ST776 lid is what you want when the original is cracked, chipped, or missing off an ST776 tank. Matching by part number rather than by eye is the only reliable way to get a lid that seats correctly.
2) My Toto toilet tank lid is broken. Do I have to replace the whole tank?
No. The lid is sold on its own as an assembly, so a cracked or broken lid on an ST776 tank is a parts replacement, not a tank or toilet replacement. Order the TCU776CR#01 lid, confirm your tank is an ST776, and the rest of the fixture stays in place.
3) Will the Toto ST776 tank lid fit another Toto tank model?
Plan on ST776 tanks only. The TCU776CR#01 is the lid assembly made for the ST776 tank, and Toto lids are keyed to the tank they were molded for. If the tank in your building is a different Toto model, look up the lid part for that specific tank number rather than trying this one. The tank model is usually stamped inside the tank or on the back of the china.
4) Does the Toto ST776 tank lid come with any trip lever or internal tank parts?
It's the lid assembly on its own. Flush valve, fill valve, trip lever, and tank-to-bowl hardware are separate parts, so if you're rebuilding an ST776 tank rather than just replacing a damaged lid, order those items alongside it.
5) Is there more than one finish option for the Toto TCU776CR#01 tank lid?
One configuration only: TCU776CR#01. There is no size or finish choice to specify when ordering, so the part number is the whole order. For a property manager standardizing restrooms across a floor, that means every ST776 tank takes the same lid with nothing else to match.
