Taking its design cues from traditional Craftsman furniture, the KOHLER® Archer line of baths reveals beveled edges and curved bases for a clean, sophisticated style. This 72" x 36" rectangular drop-in bath's heated surface warms the back and neck with adjustable temperature settings to create a soothing, spa-like environment. A low step-over height offers easy access while allowing deep, comfortable soaking. A lumbar arch gently support the natural curves of your body.
