Underscore™

The KOHLER Underscore 60" x 30" alcove bathtub with Bask® heated surface and a right-hand drain delivers a soothing, spa-like soak right in your own bathroom. Streamlined with contemporary flair, this rectangular alcove bath features a warming surface for your back, shoulders, and neck, with three adjustable temperature settings so you control the level of warmth. A slotted overflow drain allows for a deep soak, and the sloped backrest, paired with integral lumbar support, keeps you comfortable from the first minute to the last. An integral flange simplifies installation and helps prevent water from seeping behind the wall, supporting a straightforward alcove installation. From morning routines to evening wind-downs, this soaking bath offers the fit, warmth, and comfort you want in an alcove bathtub. Choose the Underscore bath with Bask® technology to make gentle warmth part of your everyday routine.
