Kohler Underscore 72" Bathtub vs Streamline N-4160 72 in. Acrylic Soaking Tub

Buy the Kohler Underscore if you want a wide, deep tub with a heated surface and a lifetime warranty. Buy the Streamline N-4160 if your alcove is 36 inches wide and you want a lighter tub with a finished drain included. The Kohler is the better-built tub: thicker acrylic, a 139-gallon capacity and a sloped backrest that owners of Underscore baths consistently praise. The Streamline is a basic acrylic soaker with a 5-year warranty and a 16-inch soak depth that leaves shoulders exposed.

• Choose the Kohler Underscore if you have room for a 42-inch-wide drop-in and want the deepest soak, a heated backrest surface and a lifetime limited warranty.
• Choose the Streamline N-4160 if your alcove is 36 inches wide, you want a lighter tub to carry upstairs, and the included oil-rubbed bronze drain matches your fixtures.
