TOTO TCU646VCRE#51 – Frequently Asked Questions
1) What toilet does the Toto TCU646VCRE#51 tank lid fit?
The TCU646VCRE#51 is the china tank lid for the Toto CST646CEMFGNAT40 toilet. Tank lids are model-specific, so it seats on that tank and no other. If the toilet in your building is a different Toto model, the lid will not sit correctly, and you need the lid keyed to that model number instead.
2) Will a Toto tank lid from another CST model work on a CST646 toilet?
No. Toto molds each tank lid to the tank it ships with, and the CST646CEMFGNAT40 takes the TCU646VCRE#51. A lid from a different series will either overhang, rock, or fail to clear the flush tower. Match the tank lid to the toilet's full model number, not just the brand.
3) Is the Toto TCU646VCRE#51 a replacement lid only, or does it come with tank trim?
It is the vitreous china lid by itself. No fill valve, flush valve, trip lever, or tank-to-bowl hardware comes with it. Property managers replacing a cracked or missing lid get exactly the ceramic piece; anything else broken inside the tank has to be ordered separately.
4) What does the #51 suffix mean on Toto part TCU646VCRE#51?
On Toto part numbers the code after the hash is the finish. TCU646VCRE#51 is the single finish this lid is sold in, so there is no color choice to make when ordering; the base number TCU646VCRE plus #51 is the complete part number to quote.
5) Our maintenance crew broke a toilet tank lid. Do we have to replace the whole toilet?
No, the lid is sold as a standalone china piece. For a Toto CST646CEMFGNAT40 the replacement is TCU646VCRE#51, which drops onto the existing tank with no plumbing work at all: shut nothing off, set the lid on, done. That keeps a fleet of identical fixtures uniform instead of introducing an odd toilet into the building.
6) Is the Toto TCU646VCRE#51 lid ceramic or plastic?
Vitreous china, the same material as the tank it covers, which is why the finish and sheen match an existing Toto fixture rather than standing out the way a plastic aftermarket lid does. It also means it will chip or crack if dropped, so handle it as you would the tank.
