Streamlined for simplicity, the KOHLER Underscore oval bath exudes refined style with contemporary flair. The Bask heated surface warms your back, shoulders, and neck with adjustable temperature settings to create a soothing, spa-like environment. A slotted overflow drain allows for a luxuriously 65-1/2” x 35-3/4” oval drop-in deep bath as you relax against the comfortable sloped backrest.
