TOTO TCU646VCRE#11 – Frequently Asked Questions
1) Which Toto toilet does the TCU646VCRE#11 tank lid fit?
The TCU646VCRE#11 is the vitreous china tank lid made for the Toto CST646CEMFGNAT40 toilet. It is a model-specific replacement lid, so match the toilet model exactly rather than going by tank shape, since Toto lids are not interchangeable across tank bodies.
2) I cracked a toilet tank lid in one of my units. Can I buy just the lid from Toto instead of a whole tank?
Yes. TCU646VCRE#11 is sold as a standalone china tank lid for the CST646CEMFGNAT40, so a cracked or chipped lid does not mean replacing the tank or the toilet. Finish code #11 (Colonial White) ships with it, so the replacement matches the original china color on that model.
3) Does the Toto TCU646VCRE#11 come with the flush valve or trip lever?
No. It is the china lid only. Flush valve, fill valve, flapper, trip lever and tank-to-bowl hardware are separate parts, so if the tank took a hit hard enough to break the lid, check the trim separately and order those pieces on their own.
4) Will a Toto tank lid from a different model fit my CST646 toilet?
Plan on no. Toto china lids are cast to a specific tank, and this one is specified for the CST646CEMFGNAT40. Lids from other series will sit proud, rock, or not cover the opening, and the lid also has to clear the flush actuation on that model. Order by the toilet's model number stamped inside the tank.
5) What color is the #11 suffix on a Toto part number?
On Toto, the digits after the # are the china color code, and #11 is Colonial White, an off-white rather than the brighter cotton white (#01). If the toilet in the bathroom is Colonial White, TCU646VCRE#11 is the matching lid; a #01 lid will read noticeably cooler next to it.
6) Is this a plastic or ceramic toilet tank lid?
Ceramic. It is a vitreous china lid, same material as the tank itself, which is why it matches in color and gloss but will chip or crack if dropped. Handle it flat and set it on a towel, not on edge, during valve service.
