TOTO TCU646VCRE#12 – Frequently Asked Questions
1) Which Toto toilet does the TCU646VCRE#12 tank lid fit?
The TCU646VCRE#12 is the vitreous china tank lid for the Toto CST646CEMFGNAT40 toilet. It is a replacement lid only, so match the lid part number to the toilet model before ordering. Tank lids are model specific, and a lid from a different Toto tank will not seat correctly.
2) Is this a whole toilet tank or just the lid?
Just the lid. The TCU646VCRE#12 is the china top that sits on the tank, with no tank body, no flush valve, fill valve, or trip lever included. If the tank itself is cracked you need the tank assembly, not this part.
3) I manage an apartment building and a tenant broke a Toto toilet lid. Can I replace the lid alone instead of the whole toilet?
Yes, that is exactly what this part is for. A broken or chipped lid on a Toto CST646CEMFGNAT40 gets replaced with the TCU646VCRE#12 china lid, no plumbing work involved. The lid simply lifts off and sets back on, so a maintenance tech can swap it in minutes without shutting off the supply.
4) Will a Toto tank lid from another model fit my CST646CEMFGNAT40?
No. Toto tank lids are cast to the specific tank they belong to, and the TCU646VCRE#12 is matched to the CST646CEMFGNAT40 tank. A lid from a different Toto series will sit proud, rock, or leave gaps at the rim. Identify the toilet model first, then order the lid keyed to it.
5) What does the #12 at the end of the Toto lid part number mean?
On Toto part numbers the suffix after the # is the finish code, and #12 is Toto's Sedona Beige. Order the lid in the same finish code as the toilet it sits on or the color will not match, since Toto china colors differ noticeably side by side.
6) What is the Toto china lid made of and will it hold up in a commercial restroom?
It is vitreous china, the same fired glazed material as the toilet tank itself. That glazed surface cleans with standard restroom chemicals and will not stain or discolor like a plastic lid. The tradeoff is that china chips if dropped, which is the usual reason a facility ends up buying this part.
7) Do I need any hardware or sealant to install this Toto tank lid?
No hardware. The lid rests on the ground rim of the tank under its own weight, so there are no screws, gaskets, or adhesive involved. Set the old lid aside, wipe the tank rim clean, and place the new one flat.
