Toto AQUIA TANK LID - BONE TCU412CR#11

TCU412CR is the ceramic tank lid by itself, a replacement cover for a Toto Aquia toilet tank. No flush valve, fill valve, trip lever or tank-to-bowl hardware comes with it. If your lid cracked or walked off during a turnover, this is the piece that puts the tank back to original; anything inside the tank is ordered separately.

Match on the tank model number, not on the toilet name. Toto tank lids are cut to one specific tank, and the Aquia family has run across several tank versions, so a lid for one will sit proud or rock on another. Pull the lid off and read the number moulded inside the tank or stamped on the underside of the old lid, then order the lid built for that tank. TCU412CR is the Aquia lid. Colour also has to be matched to the toilet's Toto colour code so the glaze matches the tank and bowl.

The digits after the hash are Toto's colour code, and they are part of the ordering number, not a packaging detail. TCU412CR is the Aquia lid itself; the suffix tells the factory which glaze to ship. When you order, give the full string including the suffix, otherwise you can end up with the right shape lid in the wrong shade sitting on the tank.

Yes, and it is worth doing if your units were fitted out with the same Aquia toilet. Lids are the most commonly broken vitreous china part in a rental turnover and they are not interchangeable between toilet models, so one spare that matches your standard tank saves replacing a whole two-piece toilet over a dropped cover. Confirm every unit runs the same Aquia tank before you buy in quantity, since a building fitted out in phases often has more than one tank version.
