Toto ULTRAMAX II 1PC TANK LID TCU604CRE#12

TCU604CRE#12 is the china tank lid only for the Toto Ultramax II one-piece toilet. No tank body, no trim, no flush valve or fill valve comes with it. It's the replacement part you order when the original lid was cracked or dropped and the toilet itself is fine.

On Toto part numbers the code after the hash is the color, so TCU604CRE#12 is the Sedona Beige version of the Ultramax II one-piece lid. If your toilet is cotton white or colonial white, the lid body is the same casting but you need the matching color suffix, because a beige lid on a white bowl is an obvious mismatch. Match the suffix stamped on your existing toilet before ordering.

No. It's cut for the Ultramax II one-piece tank deck and nothing else. Toto one-piece models (Ultramax, Ultramax II, Aquia, Carlyle, Vespin, Nexus) all have different tank shapes, so a lid from one won't seat on another. Pull the model number off the china, usually stamped inside the tank or under the lid, and confirm it's an Ultramax II before ordering.

Yes, and that's exactly what this part is for. The Ultramax II lid is a separate serviceable china piece, so a cracked or chipped lid doesn't mean replacing a working toilet. Keeping one or two on the shelf per color used in the building is normal practice for multi-family and hospitality maintenance.

Nothing to install. The lid sets down on the tank rim under its own weight, no bolts, gasket, or sealant. Set it on square so the flush button or handle linkage isn't fouled, and be aware china lids chip easily at the edges when set down on a hard surface during the swap.
