TOTO THU6442#01 – Frequently Asked Questions
1) What exactly is TOTO THU6442#01?
THU6442#01 is a TOTO toilet tank lid, square shape, in the Cotton White finish (TOTO's #01 color code). It is a replacement lid only, not a full tank or a complete rough-in kit, so it ships as the ceramic cover that sits on top of the tank.
2) Will a TOTO tank lid from another model fit my toilet if the shape looks the same?
No. TOTO tank lids are matched to a specific tank model, and the seating rim and overall footprint change between series even when both lids look square. Order by the lid part number that matches your tank, which for this one is THU6442#01 in Cotton White. If your tank calls for a different THU number, this lid will not seat correctly.
3) Does the #01 suffix on THU6442 mean Cotton White?
It does. On TOTO part numbers the trailing color code identifies the finish, and #01 is Cotton White, which is what this square lid is supplied in. If your fixtures are Colonial White or Sedona Beige, the color will not match and you need the lid in that code instead.
4) I manage a building with a lot of TOTO toilets and a tenant broke a tank lid. Can I just buy the lid?
Yes, that is exactly what this is. THU6442#01 is sold as a standalone square tank lid in Cotton White, so a cracked or chipped cover can be swapped without touching the tank, trip lever, or flush valve. Match the part number to the tank you are repairing before you order in quantity for a fleet of toilets.
5) Does the TOTO THU6442#01 lid include the flush button or trip lever?
No. It is the ceramic tank lid alone. Any push-button assembly, trip lever, or trim you need stays with your existing tank or gets ordered separately as its own TOTO part.
6) Is any installation or plumbing work needed to fit a TOTO square tank lid?
None. The lid sets onto the tank rim under its own weight, with no fasteners, gaskets, or supply connections involved. Shut the water off only if you are also servicing the tank internals; for a straight lid replacement you just lift the old one off and set the new one on.
