TOTO TCU446CRE#51 – Frequently Asked Questions
1) What exactly is the TOTO TCU446CRE#51 part?
It's a vitreous china toilet tank lid, not a complete tank or toilet. TOTO part number TCU446CRE#51, the replacement lid for the ST446E tank. If you've cracked or chipped a lid and the tank itself is sound, this is the piece that replaces it; the trip lever, flush valve and fill valve are separate parts.
2) Will the TCU446CRE lid fit any TOTO tank, or only the ST446E?
Only the ST446E. TOTO tank lids are model specific, matched to the tank's footprint and the lever cutout, so a lid from another tank won't seat correctly. Check the model number stamped inside your tank before ordering, and order TCU446CRE if it reads ST446E.
3) Does the #51 suffix on TCU446CRE#51 mean a particular color?
Yes, the #51 is TOTO's color code suffix, and it's the only finish code this lid is offered in. When you order, include the full suffix: a lid ordered without it may not match the tank and bowl color.
4) I manage a building with several TOTO toilets. Can I stock one lid to cover them all?
No. Lids are tied to the specific tank model, so a single spare won't cover a mixed fleet. The TCU446CRE serves ST446E tanks only. If you're standardizing, record the tank model and color suffix for each restroom and keep a spare lid per tank model rather than one universal part.
5) Does the TOTO tank lid come with the flush lever or any mounting hardware?
It's the china lid alone. No trip lever, no gasket, no bolts, nothing fastening it down, it rests on the tank rim. If your lever is broken too, order that separately for your tank model.
