Our take on the KOHLER K-1137-0 Underscore 72" X 42" Drop-In Bath

The Kohler Underscore K-1137-0 is a large rectangular drop-in bathtub, 72 inches long and 42 inches wide, with a sloped backrest and a slotted overflow drain that lets the water sit deeper than a standard overflow. It is built for a roomy alcove or a generous deck surround, and its clean lines suit modern bathrooms. Against typical 60-inch tubs it gives noticeably more soaking length and width, but its size demands a large footprint and a deck that supports it. Owners of Kohler's Underscore line generally praise the deep soak and solid acrylic feel.

Questions and answers

Is this tub big enough for two people?
At 72 by 42 inches it is wider than most tubs, so two adults can share it, though it is still a standard-depth bath rather than a two-person whirlpool.
Does the slotted overflow really make it deeper?
Yes. The slotted overflow sits higher than a conventional round overflow, so the water can fill closer to the rim.
What kind of installation does it need?
It is a drop-in tub, so it needs a deck or surround built around it and a properly supported floor underneath.
Is it acrylic or cast iron?
It is an acrylic bath, which keeps it lighter than cast iron but requires a solid bed of support to prevent flex.
Does it come with a faucet or drain?
No. The tub is sold on its own, so the faucet, drain and overflow trim are chosen separately.
Will it fit a standard alcove?
No. At 72 by 42 inches it needs a larger alcove or a custom deck than a typical 60-inch tub.
Where is the KOHLER K-1137-0 Underscore 72" X 42" Drop-In Bath cheapest?
