TOTO TCU646VCRE#03 – Frequently Asked Questions
1) Will the Toto TCU646VCRE#03 tank lid fit my toilet?
The TCU646VCRE#03 is the vitreous china tank lid made specifically for the Toto CST646CEMFGNAT40 toilet. Tank lids are model-specific, so it only fits that tank, not other Toto two-piece models. Check the model number stamped inside your tank or under the lid before ordering.
2) I cracked the lid on a Toto toilet in one of my units. Can I buy just the lid instead of a whole new toilet?
Yes. Toto sells the china tank lid as a standalone replacement part, and TCU646VCRE#03 is the one for the CST646CEMFGNAT40. For property managers, replacing the lid alone keeps the existing tank, trim, and rough-in untouched, so there is no plumbing work involved.
3) Is the TCU646VCRE#03 a cotton white lid, or do I need to match a color?
The #03 suffix in TCU646VCRE#03 is Toto's color code, and it must match the color code on your toilet. If your toilet's model number ends in a different suffix, the glaze will not match and you need the lid coded to your toilet's color.
4) Does this Toto lid include the flush handle or trip lever?
No. TCU646VCRE#03 is the china lid only, with no trim, flush lever, or tank hardware. If the lever or flush valve also failed, order those separately.
5) Does installing a Toto china tank lid require any tools or hardware?
No tools needed. The china lid simply sets on top of the tank and rests in place by its own weight, so it is a drop-on replacement once you have the correct lid for the CST646CEMFGNAT40 tank.
