Our take on the KOHLER K-20201-LA Underscore 60" x 30" alcove bath with integral apron, integral flange, and left-hand drain

The Kohler Underscore K-20201-LA is a 60-inch by 30-inch acrylic alcove bathtub with a left-hand drain. Its integral apron gives a finished front without a separate panel, and the integral flange helps keep water out of the wall during alcove installation. The 19-inch step-over height keeps the same soak depth as a standard 21-inch tub while making it easier to climb in, and the sloped backrest with lumbar support is shaped for longer soaks. It suits remodelers replacing a standard alcove tub, especially anyone who wants easier entry or an ADA-compliant bath. Against cast iron and heavier composite tubs it is lighter and simpler to install, but acrylic flexes more and holds heat less well than enameled cast iron.

About the KOHLER K-20201-LA Underscore 60" x 30" alcove bath with integral apron, integral flange, and left-hand drain

The KOHLER Underscore is a 60" x 30" acrylic alcove bath with a left-hand drain. An integral apron gives the front a clean, finished look. An integral flange helps keep water from seeping behind the wall and simplifies alcove installation.

The step-over height is 19", while the bath keeps the same depth as a standard 21" bath. A slotted overflow allows for deep soaking. Integral lumbar support and a gently sloped backrest add comfort, and the bottom surface is textured.

The bath is ADA compliant and suitable for residential use.

Questions and answers

Does the Kohler Underscore K-20201-LA fit a standard alcove?
Yes. It is 60 inches long, 30 inches wide and 20-1/4 inches high, sized for a standard alcove opening. The drain is on the left, so check your rough-in before ordering.
How is this different from a standard 21-inch tub?
The step-over height is 19 inches instead of 21, which makes climbing in easier while keeping the same soak depth. That lower entry is also what makes it ADA compliant.
Is the drain included?
No. The tub has a left-hand drain outlet, but the drain trim and overflow kit are sold separately. Kohler's installation guide lists the compatible drain options.
What does the slotted overflow do?
It lets water sit higher before draining, so you can soak deeper than with a standard round overflow. It still prevents overflow if the tub is overfilled.
Is acrylic a good choice for a bathtub?
Acrylic is light, warm to the touch and easy to install, which suits alcove replacements. It does not hold heat as long as cast iron and can flex or scratch, so it is a trade-off rather than an upgrade.
Does it need a separate apron or tile surround?
No apron panel is needed because the apron is molded into the tub. The integral flange tucks behind the wall finish to help keep water out.
