TOTO TCU654CR#51 – Frequently Asked Questions
1) What exactly is the TOTO TCU654CR#51 part?
It's a replacement ceramic tank lid for a TOTO Aquia toilet, sold on its own as a spare part. You get the lid only, no tank, no trip lever, and no internal trim. If the tank itself is cracked or the flush hardware is what failed, this isn't the part that fixes it.
2) My Toto tank lid broke - how do I know I'm ordering the right replacement lid?
Tank lids are model specific, so match it by the part number TOTO prints under the lid or on the tank, not by appearance. This one is TCU654CR#51, the Aquia lid. If the number stamped on your old lid or tank is anything else, order that number instead, since a lid from a different TOTO series will not seat correctly on the tank rim.
3) Is the #51 in TCU654CR#51 a color code?
Yes. On TOTO parts the suffix after the # is the finish code, so TCU654CR#51 is the Aquia lid in that specific TOTO color. Order the suffix that matches the rest of your fixture; a lid in the wrong color code will fit but will not match the bowl and tank.
4) Does a replacement Aquia tank lid come with the flush button or trip lever?
No. The TCU654CR#51 is the lid alone. Aquia dual-flush models use a push-button trim that mounts through the lid, and that trim is a separate part. If your button assembly is broken or missing, order it separately along with the lid.
5) Is a tank lid worth replacing on its own, or should I swap the whole toilet?
For property managers and maintenance crews, the lid is a routine standalone replacement - no water shutoff, no re-setting the bowl, no wax ring. A cracked or missing lid is cosmetic and a theft/vandalism item in multi-family and commercial restrooms, so stocking the matching lid number keeps the fixture in service without touching the rough-in.
