TOTO TCU646VCRE#01 – Frequently Asked Questions
1) What toilet does the TOTO TCU646VCRE#01 china lid fit?
The TCU646VCRE#01 is the replacement china tank lid for the TOTO CST646U tank, specifically the CST646CEMFGNAT40 configuration. It is the lid only, not a tank or a complete toilet, so order it when the original lid is cracked or chipped and the tank itself is sound.
2) Can I order just the tank lid for a TOTO CST646U instead of replacing the whole toilet?
Yes. TOTO sells the china lid on its own under part number TCU646VCRE#01, matched to the CST646CEMFGNAT40 tank. For a property manager with a broken lid in a unit, that is a single part swap, no plumbing work involved.
3) Will a TOTO tank lid from a different model fit my CST646U?
No. TOTO tank lids are model specific and are cast to the rim profile of one tank. The TCU646VCRE#01 is the lid made for the CST646U (CST646CEMFGNAT40) and a lid from another TOTO tank will not seat correctly. Match the lid part number to the tank, not to the brand.
4) What color is the TCU646VCRE#01 TOTO tank lid?
The #01 suffix on the part number is TOTO's Cotton White code, so the lid is Cotton White to match a CST646U tank in the same finish. If the tank in the building is a different TOTO color, the lid code changes with it.
