TOTO TCU654CR#01 – Frequently Asked Questions
1) Will the TOTO TCU654CR#01 tank lid fit my Aquia toilet?
The TCU654CR#01 is the china tank lid made for the TOTO CST646CEMFGNAT40 Aquia one-piece toilet. It is model-specific: TOTO tank lids are cast to the tank they ship on, so it fits that CST646CEMFGNAT40 tank and not other Aquia tanks. Check the model number stamped inside your tank or on the china before ordering.
2) I cracked the lid on my Aquia toilet. Can I buy just the lid instead of a whole new toilet?
Yes. The TCU654CR#01 is sold as a standalone replacement part, so a cracked or chipped lid on a CST646CEMFGNAT40 Aquia does not mean replacing the fixture. It is the china lid only, no trip lever or internal trim included.
3) I manage a building with several TOTO Aquia toilets. Can I stock one lid that fits all of them?
Not with this one. The TCU654CR#01 covers the CST646CEMFGNAT40 tank only. Aquia has run through several tank generations with different lid castings, so a facility with mixed Aquia vintages needs the lid matched per tank model. Pull the model number off each tank and order by that, not by the Aquia name.
4) Is the TOTO TCU654CR#01 lid ceramic or plastic?
Vitreous china, same material as the tank it sits on. That is why it chips rather than flexes, and why it wipes down with the same cleaners you use on the rest of the fixture.
5) Do I need any tools or parts to install a replacement TOTO Aquia tank lid?
No installation involved. The TCU654CR#01 sets onto the tank rim under its own weight, so there is nothing to bolt, seal, or plumb. Set the old lid aside, lower the new one on, and check that it seats flat and does not rock against the trip lever.
