I have the Kohler Underscore drop-in 36" x 60." I love it. Is this going to be a tub-only or will it be a tub/shower combo? The Underscore has a slanted back and lumbar support. If it's a tub/shower combo, you'd have to be careful not to step on the slanted/lumbar area. Our tub/shower combos have tubs that are not very slanty.
