TOTO TCU424CRS#12 – Frequently Asked Questions
1) Will the TOTO TCU424CRS#12 lid fit my ST424S toilet tank?
Yes. The TCU424CRS#12 is TOTO's replacement tank lid made specifically for the ST424S tank, so it is the matching part rather than a universal cover. Tank lids are molded to one tank body, so ordering by the tank model (ST424S) is the only reliable way to get a lid that seats correctly.
2) Is this TOTO lid a generic toilet tank cover that fits several models?
No, and this is where most orders go wrong. TCU424CRS#12 is cut for the ST424S tank only. Toilet tank covers are not interchangeable between models or even between color runs, so if your tank is stamped with a different ST number you need that tank's lid, not this one.
3) I broke a toilet tank cover in one of my units. Can I buy just the lid from TOTO instead of a whole tank?
You can. TCU424CRS#12 is sold as a standalone spare tank lid for the ST424S tank, which is the usual fix for a cracked or chipped cover in a rental or hotel bathroom. No other tank trim comes with it, so if the flush valve or fill valve is also failing those are separate parts.
4) What does the #12 suffix mean on TOTO part number TCU424CRS#12?
On TOTO part numbers the code after the # is the finish. TCU424CRS#12 is the Sedona Beige version of the ST424S tank lid. If the tank on the fixture is cotton white or another color, the base number stays TCU424CRS and the suffix changes, so match the suffix to the tank you are covering.
5) Does a TOTO tank lid come with the flush handle or any mounting hardware?
No. The TCU424CRS#12 is the ceramic cover only. Tank lids on TOTO two-piece toilets rest on the tank rim and are not bolted down, so there is no gasket or fastener kit involved. Trip levers, fill valves and flappers are ordered separately.
6) Where do I find the tank model number to confirm I need the ST424S lid?
Lift the existing cover and look inside the back wall of the tank. TOTO stamps the tank model (for example ST424S) into the china there, usually near the date code. If it reads ST424S, TCU424CRS#12 is the matching beige replacement cover.
