Our take on the KOHLER K-1821 Underscore 66" x 32" drop-in bath

The KOHLER Underscore K-1821 is a 66-inch rectangular acrylic drop-in tub with a clean, contemporary look. Its sloped backrest and integral lumbar support give more back support than a flat-back tub, and the slotted overflow lets you fill the water higher for a deeper soak. At 66 x 32 inches it fits alcoves and standard tub surrounds that a longer 72-inch tub would not. It is a soaking tub only, with no jets, so it competes with other acrylic soakers on comfort and depth rather than on massage features.

Questions and answers

Does the KOHLER Underscore K-1821 include a drain?
No. It needs a KOHLER Clearflo slotted overflow bath drain, either the K-7271 brass or K-7272 version, bought separately. The slotted overflow is what allows the deeper fill.
How does it compare with a 72-inch Underscore tub?
It is 6 inches shorter, so it fits alcoves where a 72-inch tub will not. The trade-off is less length to stretch out, though the sloped backrest and lumbar support help make up for it.
Is this a jetted or whirlpool tub?
No. It is a plain soaking bath with no jets or air blowers. Shoppers who want massage features need a whirlpool model instead.
What are the outside dimensions?
66 inches long, 32 inches wide and 22 inches high, weighing about 110 pounds. Check your rough opening before ordering, since drop-in tubs sit in a framed deck.
Can it be used in a rental or residential bathroom?
KOHLER lists it for residential use. It is a standard drop-in acrylic tub, so installation follows the usual deck and drain requirements.
Where is the KOHLER K-1821 Underscore 66" x 32" drop-in bath cheapest?
At KOHLER Stores by General Plumbing Supply, for $1,558.42, as of our latest check.
