With its tight corners and long, straight lines, Kohler's Underscore collection of baths offers the best design in all the right sizes. Featuring a contemporary undermount installation, the Underscore perfectly complements the use of natural materials in your bathroom, including granite, stone, and tile. A specially molded lumbar support ensures bathing comfort while providing additional floor space in the bath.
The roomy Underscore bath (6-foot version shown with brass slotted overflow drain; view larger).
This version of the Underscore measures 5-feet in length, but it also comes in 5.5- and 6-foot sizes. It's also available with Kohler's BubbleMassage functionality in the 5-, 5.5-, and 6-foot sizes. It's available in 10 colors, including almond, biscuit, black black, cashmere, dune, ice grey, Mexican sand, sandbar, thunder grey, and white.
The Underscore works with Kohler's Clearflo slotted overflow bath drain (required, available separately), which offers approximately 2 inches of increased soaking depth and a toe tap-style drain. It is installed on one of the ends of the tub.
This Underscore tub measures 60 inches long by 32 inches wide by 21 inches deep, has a water depth of 17-1/8 inches, and offers an 81-gallon capacity. Floor support under the bath must provide for a minimum of 50 pounds per square foot of load, and the hot water supply should be 70 percent of the bath or greater (56.7 gallons). It's backed by a 1-year limited warranty.

Installed today and discovered the tub had a bow in it. Did not notice this in the box or when handling. It's sitting on a level surface and you can see the 3/16" rise in the middle. This is on both sides. Disappointed as it's an expensive tub designed for sitting on a flat surface.I recommend you do not buy this tub. Go with a heavier cast tub

This is a great tub. I have used Jetted tubes in the past. But I have a spa in my pool. Jetted tubes hold bacteria. This is the most comfortable soaking tube my ladies have ever sat in. The biggest problem is getting it delivered. That was a pain in the ass.

Deep drop-in tub. Made the most out of a small bathroom!

This tub is fabulous. The position of the overflow drain (and the shape) mean you can make the bath very very deep. Other Koehler and other brand rubs may have higher sides, but it’s pointless if the water can only go up to the level of the overflow.Other positives: no texture on floor (good if you’re a soaker, not so good if you have little kids who will stand up in it), good recline angle, holds up well (this is my 3rd one, in different bathrooms, and I love them all!)

Woohoo! This is a great bathtub. My only regret is that I only had 60" of space so I couldn't order a 6 ft. model.Shell is heavy and well-braced. No flex when seated into thinset. The deepest water depth I could find. Far superior product compared to the best alternatives I could find at a big box store.

Tub arrived quickly and without a dent in the box. The instructions are next to nothing and I'll have to build the frame by taking my own measurements. Tub feels slick and I'm happy with finish. I hope I'm as happy after the install!

I got this to fit the space I had for a tub when I remodeled my master bath. It is deeper than the usual tub so works well for my husband and I, who are both tall. I got the nickel hardware. The drain popup closes with a push, then opens with another push. Fabulous - just don't sit on it and open it by mistake : ).I go the Price Pfister Kenzo spread faucet and matching handheld shower with this. I have no complaints about this tub - and the delivery was great too.
