Which is better for deep soaking?

The Streamline holds 63 gallons with a 16.1 inch soaking depth; the Kohler holds 60 gallons at 13-1/4 inches. The Streamline soaks deeper, though the Kohler's slotted overflow is designed to let you fill higher than a standard overflow.

Is the Kohler worth the extra money?

At $1,136.62 at Amazon versus $224.00 at Streamline Bath as of November 6, 2026, you pay about $900 more for the Kohler name, a lifetime limited warranty, a preinstalled color-matched drain, and molded back and neck support. If warranty and brand support matter to you, it can be worth it.

Both are acrylic. The Kohler backs its tub with a lifetime limited warranty, which is the stronger long-term guarantee. The Streamline lists no written warranty, so its lifespan depends on the 3.8 mm acrylic shell holding up.

Will either fit a 72 x 36 inch alcove?

Both are 72 inches long and 36 inches wide and are drop-in models, so the rough opening is the same. Check the drain location: the Kohler drain is on the left, and the Streamline uses an external drain you route yourself.

Which is easier to install?

The Kohler ships with an integral overflow and a preinstalled toe-tap drain, which cuts plumbing work. The Streamline includes an external drain and adjustable leveling feet, which help on uneven floors but add drain assembly.

Do the drains match common fixtures?

The Kohler drain is color-matched to the tub, so it matches the bath but not necessarily your faucet. The Streamline's matte oil rubbed bronze drain suits oil rubbed bronze fixtures and clashes with chrome or brushed nickel.
