TOTO TCU743BCR#01 – Frequently Asked Questions
1) What exactly is TOTO part TCU743BCR#01?
TCU743BCR#01 is a TOTO toilet tank lid sold as a replacement part, not a complete tank or toilet. You get the lid only, so the tank, trip lever, and flush valve internals stay as they are. Order it by that full part number including the #01 suffix, since TOTO codes the finish into the number.
2) Can I buy just the toilet tank lid instead of replacing the whole toilet?
For a cracked or missing lid, a china replacement lid like TCU743BCR#01 is the normal fix. It is a toilet application part, so nothing in the bowl or the supply line is disturbed, and for a property manager it keeps a unit in service without a plumber pulling the fixture. The one thing to get right is the part number, because tank lids are tank-specific and will not interchange across models.
3) Will a TOTO tank lid from another model fit my tank if the size looks close?
No. China tank lids are moulded to one tank's rim profile and trip lever cutout, so a lid from a neighbouring TOTO model usually sits proud or rocks even when the footprint looks similar. TCU743BCR#01 is a model-specific replacement lid. Pull the model number stamped inside your tank and order the lid called out for it.
4) Does the #01 on the end of TOTO TCU743BCR#01 mean a color?
Yes. On TOTO part numbers the trailing code is the china color, and #01 is Cotton White. If the toilet in the restroom is a different TOTO color, the matching lid carries a different suffix, so match the suffix on the tank you are replacing rather than just the TCU743BCR base number.
5) Does a replacement TOTO tank lid come with flush handle or tank hardware?
No, TCU743BCR#01 is the china lid by itself. Trip levers, flappers, fill valves, and tank-to-bowl hardware are separate parts. If the handle is also broken, order the trip lever for your tank model at the same time so you are not back at the fixture twice.
