Our take on the Kohler Underscore 60 in. x 30 in. Alcove Bathtub

The Underscore is Kohler's 60-inch acrylic alcove tub, sized for standard three-wall alcoves and built with an integral apron and tile flange to simplify installation. Its 58-gallon basin and 15-inch water depth make it deeper than many builder-grade tubs of the same footprint, so it soaks rather than just showers. Acrylic keeps it lighter than cast iron at about 80 lbs, though it feels less solid underfoot than enameled cast iron. It suits remodelers replacing a standard tub and anyone who wants a deeper soak without moving plumbing.

Pros

  • Smooth acrylic surface is easy to wipe clean
Cons

Questions and answers

Does it fit a standard 60-inch alcove?
Yes. It is 60 inches long and about 32 inches wide, sized for a standard three-wall alcove. Check your rough opening and drain location before ordering.
Can the drain go on either side?
Yes. It comes in left- and right-hand drain versions, so pick the one that matches your plumbing.
Does it need a mortar bed?
Kohler's instructions call for setting the base in mortar or an approved foam bed. Skipping it is the usual cause of a flexing floor.
How does it compare with a cast iron tub?
It is far lighter and easier to install, but acrylic flexes more and does not hold heat as long as enameled cast iron.
Is the tile flange included?
Yes. The tile flange is molded into the tub, so tile can be set against it without a separate kit.
How much water does it hold?
About 58 gallons to the overflow, with a 15-inch water depth.
