TOTO TCU784CR#11 – Frequently Asked Questions
1) What does the TOTO TCU784CR#11 part actually replace on a toilet?
It's the vitreous china tank lid, the ceramic cover that sits on top of the tank. It is a replacement lid only, so no flush valve, fill valve, trip lever, or tank hardware comes with it. If your tank lid cracked or chipped, this is the piece that fixes it without replacing the whole tank.
2) I manage several buildings with TOTO toilets. Will this lid work on any TOTO tank?
No. The TCU784CR#11 is dedicated to the ST784S tank and will not seat on other TOTO tank models. For a fleet of restrooms, record the tank model from inside each tank rather than the toilet's marketing name, since one bowl can pair with more than one tank over a production run.
3) What color is the TOTO TCU784CR#11 tank lid?
Bone. TOTO's color suffix system puts that at #11, and the full part number to order is TCU784CR#11. Ordering a lid in the wrong suffix gives you a correctly fitting lid in a color that won't match the bowl, so keep the #11 on the number.
4) Does the TOTO TCU784CR#11 lid come with the flush handle or tank trim?
No. It's the china lid on its own. Trip levers, fill and flush valves, tank bolts, and the tank-to-bowl gasket are separate parts, so order those alongside if the repair involves more than the cover.
5) Do I need any tools or hardware to install a TOTO china tank lid?
None. The lid sits loose on the rim of the ST784S tank under its own weight, with no fasteners or sealant involved. Set it down flat and square; china is brittle at the edges and most breakage happens from dropping the corner on the rim.
