Cahaba CATUBDRAIN Tub Big Drain Cap Hardware 3"

It is drain cap hardware, a service part rather than a complete waste and overflow assembly. If your shoe, tailpiece, or overflow tubing is what failed, this cap will not cover it; you need a full waste and overflow kit for that. Use this when the body of the drain is sound and you are replacing a damaged, corroded, or mismatched cap.

Three inches. That is the face size of the cap, so measure across the visible drain cover in your tub before ordering, a standard smaller cap will look undersized if you swap the other way.

Four finishes: Black, Brushed Nickel, Chrome, and Champagne Bronze. Finish is the only thing you pick, so match it to the tub filler and overflow plate already on the tub rather than ordering by size alone.

That is what it is built for. It is a stocked service part offered in one 3 inch size across four finishes, so you can buy the same cap for every tub in a building and just split the order by the finish each unit uses. Caps take the most abuse and the most cosmetic damage of anything on a tub waste, so keeping them on the shelf is usually cheaper than pulling full assemblies.
