TOTO TCU446CRE#01 – Frequently Asked Questions
1) Which TOTO toilet does the TCU446CRE#01 tank lid fit?
The TCU446CRE#01 is the china tank lid for the TOTO Nexus two-piece 1.28 gpf toilet built on the ST446E tank. Tank lids are model-specific in shape and seating, so match the tank number stamped inside your existing tank (ST446E) before ordering rather than going by the bowl or by the overall toilet name.
2) Is the TOTO TCU446CRE#01 just the lid, or does it come with tank trim?
Lid only. TCU446CRE#01 is the vitreous china cover for the tank, sold as a replacement part. Flush valve, fill valve, flapper, trip lever and tank-to-bowl gaskets are separate items, so if you cracked the lid that is all you need, but a leaking tank rebuild takes different parts.
3) What does the #01 suffix mean on TOTO part TCU446CRE#01?
#01 is TOTO's finish code for Cotton White. The lid is ordered as one piece with that code baked into the part number, so TCU446CRE#01 is the Cotton White lid. If the rest of your fixture is a colored TOTO finish, the code after the # has to match the tank, or the lid will read as a different white on the same toilet.
4) Can a property manager use one TOTO Nexus tank lid across a building's toilets?
Only where the tanks are the same model. TCU446CRE#01 seats on the ST446E Nexus tank and nothing else, so it standardizes across units only if those units were all specified with the same Nexus two-piece 1.28 gpf toilet. Mixed TOTO models in one building need their own lid part numbers; the tank number cast inside each tank is the thing to inventory, not the bowl style.
5) Will a universal or aftermarket tank lid work instead of the TOTO TCU446CRE#01?
No. Tank lids are not universal. This one is molded china sized to the ST446E tank rim, and TOTO tanks vary in rim profile and lid seating between series, so a lid from another model sits proud, rocks, or fouls the trip lever. Replacing a broken lid on a Nexus 1.28 gpf two-piece means ordering the matching china lid.
