TOTO THU9775 – Frequently Asked Questions
1) What exactly is TOTO part THU9775?
THU9775 is a TOTO left side cover plate, part of a base plate assembly, in the Cotton (white) finish. It is a replacement trim piece, not a functioning valve or flush mechanism, so it covers and conceals rather than operates anything.
2) Does THU9775 cover both sides of the base, or do I need the right side too?
It is the LEFT side cover only. A base plate assembly that needs both sides concealed takes a matching right side cover ordered separately under its own TOTO part number.
3) I manage a building with several TOTO fixtures. How do I confirm this cover fits the one I'm repairing?
Match by part number, not by appearance. TOTO cover plates are model specific, so the reliable check is the parts breakdown for your fixture: if it calls out THU9775 for the left side cover, this is the correct piece in Cotton. Visually similar covers from other TOTO models will not seat the same way on the base plate.
4) Is the TOTO THU9775 cover available in any finish other than Cotton?
Cotton only. THU9775 is the single orderable part number, and it is the Cotton finish version of the left side cover. If the fixture being repaired is in a Sedona Beige, Bone, or Ebony finish, the Cotton piece will not match and a different TOTO part number is required.
5) Will replacing the THU9775 cover fix a leak or a flushing problem?
No. The left side cover is cosmetic trim over the base plate assembly. Leaks and flush faults come from the valve, seals, or supply connections, so a cracked or discolored cover is the only reason to order this part.
6) Is any mounting hardware or gasket included with the TOTO left side cover?
What ships is the cover plate itself. Treat screws, gaskets, or clips as separate items and reuse the existing hardware from the base plate assembly unless it is damaged.
