TOTO TCU646CRU#01 – Frequently Asked Questions
1) Is TOTO TCU646CRU#01 just the tank lid, or does it include the tank?
It is the china tank lid only. TCU646CRU#01 is a replacement vitreous china toilet tank lid, so no tank, no trip lever, and no flush valve or fill valve come with it. If your tank body is cracked or the internal trim is failing, this part won't solve that.
2) Can I order a universal toilet tank lid instead of the exact TOTO part number?
No. Tank lids are not universal. A china lid is cast to the footprint of one specific tank, and the trip lever cutout and bevel vary by model, so a lid from another series will either sit proud of the tank or rock. Order the lid by its TOTO part number, TCU646CRU#01, matched to the tank you have.
3) What color is TOTO part TCU646CRU#01?
The #01 suffix at the end of the part number is TOTO's color code for Cotton White, which is the most common finish on TOTO toilets. If the rest of your fixture is Colonial White or Sedona Beige, the lid will not match and you need the equivalent lid in that color code.
4) How do I confirm a TOTO tank lid is the right one for my toilet before ordering?
Lift the lid and look at the underside, and also check the back wall inside the tank. TOTO stamps or embosses the tank model number there, and that is the number the lid is matched to, not the number on the bowl or the seat. Match the stamped tank model and the color code, then order the lid by part number. Guessing from the bowl shape alone is how the wrong lid gets shipped.
5) Do property managers need to keep spare TOTO china tank lids on hand?
For a multi-family or hospitality property standardized on one TOTO toilet, yes, it is worth stocking a lid or two. China lids are the part that gets dropped and chipped during cleaning or seat changes, and a replacement lid restores the fixture without touching the tank or the flush valve. Keep the spares matched to the tank model and the Cotton White #01 color code used on the rest of the fixtures.
