Mariposa 72" Drop-in Bathtub vs Kohler Windward 72" Drop-In Bath

The Mariposa is the pick if you want a whirlpool: six adjustable jets, a built-in heater and a single-speed pump come standard, and the 36-inch width fits a standard alcove. The Kohler Windward is the better soaking tub: 42 inches wide, 15 inches of water depth, 78.5 gallons, molded lumbar support and armrests, and it can seat two. Both are acrylic drop-ins with a reversible drain, so the real choice is jets versus room and comfort. Owners of acrylic tubs in this class report the finish holds up well; the Kohler's deeper basin and armrests draw the most praise from bathers, while whirlpool owners value the Mariposa's heater.

• Choose the Mariposa if you want a jetted whirlpool with a built-in heater and a narrower 36-inch footprint that drops into a standard alcove.
• Choose the Kohler Windward if you want a deep, wide soaking tub with lumbar support and armrests, and you have room for a 42-inch-wide deck.
