Deep Soak™ Drain – The innovative family of Deep Soak™ bath drains eliminate the wasted space above a standard overflow cap, allowing a higher water level in the bath, whirlpool or air bath. The result is a deeper, more luxurious soaking experience. Deep Soak™ Bathtub Drain – The Deep Soak Bathtub drain works with all standard bathtubs, raising the water level by over 2 inches! Easy to install; easy to use; hard to live without once you’ve tried it! Deep Soak™ Max Drain – The Deep Soak Max drain installs on our specially designed Evolution tubs, whirlpools and air baths. By designing the tub and drain to work together we’ve raised the water over 3 inches deeper than a standard bath drain! Indulge yourself with a spa experience every time you take a bath!
