TOTO TCU706CR#03 – Frequently Asked Questions
1) Will the TOTO TCU706CR#03 tank lid fit any toilet tank, or only the ST706?
Only the ST706 tank. The TCU706CR#03 is the vitreous china replacement lid made for TOTO's ST706 tank, and china lids are tank-specific: the rim profile and footprint are molded to one tank only. If the tank stamped inside your toilet is not an ST706, this lid will not seat correctly and you need the lid matched to that tank number instead.
2) Where do I find the tank number to confirm I need the TCU706CR#03 lid?
Lift the existing lid and look inside the tank, usually on the back wall above the water line or near the flush valve. TOTO stamps or prints the tank model there, and it reads ST followed by digits. If it reads ST706, the TCU706CR#03 china lid is the matching replacement. The number on the bowl is different from the tank number, so go off the tank marking.
3) Does this TOTO replacement come with flush handle or trip lever parts?
No. The TCU706CR#03 is the china lid by itself, nothing else. Trip levers, flush valves, fill valves and gaskets are separate parts. If you are replacing a cracked lid, that is all you need; if the flush mechanism is also failing, order those trim parts alongside it.
4) Is the #03 on the TOTO TCU706CR#03 a color code?
Yes, the suffix after the hash is TOTO's finish code, and #03 is the glaze color on this lid. Because a lid sits right on top of the tank, the code has to match the tank's code or the shade will read off. Check the full model marking on your tank, including its hash suffix, and match it.
5) Can a property manager replace a cracked toilet tank lid without touching the plumbing?
Yes. Swapping a china tank lid like the TCU706CR#03 means lifting the broken one off and setting the new one down, with no water shutoff, no draining and no tools, as long as the trip lever and fill valve are untouched. Handle it as glazed china, though: it chips on contact with tile or the tank rim, so set it down on a towel while you work.
