TOTO TCU446CRU#12 – Frequently Asked Questions
1) Will the Toto TCU446CRU#12 china lid fit my ST446 toilet tank?
The TCU446CRU#12 is the vitreous china tank lid made for the Toto ST446 tank, specifically the ST446E 1.0 GPF version. It is a replacement lid only, so the tank itself and its trim stay as they are. If your tank is stamped with a different ST model number, this lid is not the match.
2) What does the #12 suffix mean on Toto TCU446CRU#12?
On Toto part numbers the digits after the # are the color code, so TCU446CRU#12 is the Sedona Beige lid rather than a white one. If the rest of your fixture is cotton white, you want the #01 version of the same lid instead, otherwise the lid will not match the bowl.
3) I cracked the tank lid on a Toto toilet. Do I have to replace the whole tank?
No. The china lid is sold on its own, so a cracked or chipped lid on an ST446E tank is a drop-in replacement, not a tank job. Nothing inside the tank is disturbed, the fill valve and flush valve stay in place and the lid simply sets back down on the tank rim.
4) Does the Toto TCU446CRU#12 lid come with a flush button or any trim?
It is china only. The TCU446CRU#12 is the ceramic lid for the ST446E tank with no flush lever, push button, bolts, or gasket included. If your trip lever or flush mechanism is also damaged, order that separately.
5) We maintain a building with 1.0 GPF Toto toilets. Which lid do we stock for the ST446E tanks?
For ST446E 1.0 GPF tanks, the china lid is TCU446CRU, and the #12 code gives you Sedona Beige. Property managers standardizing a floor of identical fixtures should order by the tank number stamped inside the tank, since Toto lids are not interchangeable between tank models even within the same gallons-per-flush rating.
