TOTO THU6316#12 – Frequently Asked Questions

1) Is THU6316#12 just the tank lid, or does it include tank trim parts?
THU6316 is the toilet tank lid assembly itself, in a round shape. It is the ceramic lid that sits on the tank, not a fill valve, flapper, or flush lever kit. If your repair is a cracked or chipped lid, this is the right part; if the toilet is running or not flushing, you need trim or a flush valve instead.
2) What color is the TOTO THU6316#12 tank lid?
It's a beige lid. The #12 suffix on the TOTO part number is the color code, so THU6316#12 is the beige version of the THU6316 round tank lid. Matching the color suffix on the toilet you are repairing matters, because the same lid ships under different suffixes for other colors and a mismatched suffix arrives the wrong shade.
3) Will a round TOTO tank lid fit my elongated toilet?
Tank lids are matched to the specific tank casting, not to the bowl shape, and THU6316 is the round lid. Order by the tank model number stamped inside your tank rather than by bowl shape. If the lid on the toilet is a different profile than round, this one will not seat correctly.
4) I manage a building with several beige TOTO toilets. Can I stock this one lid for all of them?
Only for the tanks that specifically call out THU6316. TOTO assigns a separate lid part number per tank model, so beige color alone does not make it interchangeable. Pull the tank model from inside each tank and stock the lid number each one lists; the #12 suffix keeps the beige color consistent across whichever lids you carry.
5) Do I need any tools or extra hardware to install a TOTO tank lid?
No hardware is involved. The lid assembly simply sets on top of the tank, so replacing a broken one is a lift-off, set-on job with nothing to fasten and no water shutoff required. Handle it carefully, since it is vitreous china and chips on the rim edge.
