TOTO TCU642CRU#51 – Frequently Asked Questions
1) Is the TOTO TCU642CRU#51 just the tank lid, or does it come with the tank and trim?
It's the tank lid only. The TCU642CRU#51 is a replacement Nexus one-piece toilet tank lid, a cover casting with no tank, no fill or flush valve, and no trip lever included. If your porcelain lid cracked or walked off, this is the piece that replaces it; a broken flush mechanism needs the corresponding repair kit instead.
2) How do I make sure I order the right TOTO Nexus tank lid, since the lids look alike?
Order by the full part number including the color suffix: TCU642CRU#51. TOTO lids are model and color specific, so the base number has to match your toilet and the suffix after the # has to match the finish of the china. Pull the number stamped on the underside of your old lid or inside the tank and match it before buying, because a lid from an adjacent Nexus configuration will not seat correctly.
3) Will this Nexus lid fit a two-piece TOTO toilet?
No. This is a one-piece Nexus tank lid, and one-piece and two-piece tanks have different lid footprints and seating surfaces. For a two-piece TOTO you need the lid called out for that specific two-piece model number, not TCU642CRU#51.
4) For a property with several TOTO Nexus toilets, is stocking a spare tank lid worth it?
It's a common spare for multi-family and hospitality maintenance, because a dropped porcelain lid is one of the more frequent toilet casualties and the fixture stays in service otherwise. The catch is that the lid is tied to both the model and the china color, so stock the exact part number your units carry rather than a generic Nexus lid. Here that number is TCU642CRU#51.
5) Does a replacement TOTO tank lid need any hardware or sealant to install?
None. A toilet tank lid sits loose on the rim of the tank by gravity, so there is nothing to bolt, gasket, or caulk. Set it on, check it beds flat all the way around, and you're done. If it rocks or overhangs, you have the wrong lid number for that tank.
