TOTO TCU743CRE#12 – Frequently Asked Questions
1) What does the TOTO TCU743CRE#12 tank lid fit?
The TCU743CRE#12 is TOTO's replacement tank lid for the ST743E toilet tank. It's the ceramic lid only, not the tank, and it's matched to that specific tank model, so it won't sit correctly on other TOTO tanks. Check the model stamped inside your existing tank or on the china before ordering.
2) Is the TOTO TCU743CRE#12 just the lid, or does it include the tank and flush valve?
Lid only. The TCU743CRE#12 is a replacement tank lid, so no tank, fill valve, flush valve, flapper, or trip lever comes with it. If your tank is cracked or your flush hardware has failed, those are separate parts.
3) I broke the lid on a TOTO ST743E tank. Do I have to replace the whole toilet?
No. The lid is sold on its own as TCU743CRE#12 for the ST743E tank, so a dropped or cracked lid is a single-part fix rather than a new toilet. For property managers running a lot of the same TOTO fixture, ordering these by the tank model is the usual way to keep spares on hand.
4) How do I order the right TOTO tank lid so the color matches my toilet?
Order by the full part number including the color suffix. On the TCU743CRE#12, the #12 after the hash is TOTO's color code, and the part is stocked in that one code. If the rest of your fixture carries a different TOTO color suffix, you need the lid built for that suffix instead, since the ceramic glaze won't match across codes.
5) Will a TOTO tank lid from a different model fit the ST743E?
Not reliably. Tank lids are cut to the rim of one specific china tank, and the TCU743CRE#12 is made for the ST743E. A lid off another TOTO tank will either overhang, rock, or leave a gap at the trip lever. Match the tank model, not just the brand.
