TOTO TCU786CR#11 – Frequently Asked Questions
1) What is the TOTO TCU786CR#11 part?
TCU786CR#11 is the tank lid assembly for the TOTO ST786 toilet tank. It's a replacement part, the lid only, not a tank or a complete toilet. If you're chasing a cracked or missing lid on an ST786 tank, this is the piece that goes back on top.
2) Will the TCU786CR#11 lid fit any TOTO tank, or only the ST786?
Only the ST786. TOTO tank lids are model specific, and this one is built as the ST786 lid assembly. Match the model number stamped inside your existing tank or on the tank itself before ordering. If it reads anything other than ST786, this lid is the wrong part.
3) I have a TOTO toilet with a cracked tank lid. Do I need to replace the whole tank?
No. On an ST786 tank the lid is sold on its own as assembly TCU786CR#11, so a cracked or chipped lid is a lid swap, not a tank replacement. The tank, trip lever, and fill and flush valves all stay in place.
4) Does the ST786 tank lid come with the flush handle or any working parts?
It's the lid assembly only. The trip lever, fill valve, flush valve, and tank-to-bowl hardware are separate parts and stay with your existing tank. Order those individually if you're rebuilding the tank at the same time.
5) I manage a building with several TOTO toilets. How do I order the right lids in quantity?
Go by tank model, not by toilet name. Lift each lid and read the model number cast inside the tank: every ST786 tank takes TCU786CR#11, and a tank with a different number takes a different lid. The full part number including the #11 suffix is what identifies the exact lid, so quote it in full on the order.
