40 To 49 Gal Undermount Tubs & Whirlpools

The clean, rectangular profile of the Kaldera is designed for sublime bathing. This collection of under-mount and drop-in bathtubs comes in multiple sizes for all spaces. The faceted edges create crisp contours that enhance its ergonomic shape, for a singularly indulgent bathing experience. With a tapered angle of recline, the Kaldera makes leaning back, letting go, and lingering longer even lusher. Kaldera’s minimalist impression expresses elegance in every line.

Timeless style and deep bathing put the Lacey in a class of its own. Our most versatile tub – the Lacey affords clean lines and elegance in almost any design category. Enjoy the Lacey for all its fundamental beauty, or as a starting point to configure and customize to your own vision of perfection.

Love this tub. It is deep and great for getting your whole body immersed. The 66" x 30" is even better, but we didn't have room for it in this particular bathroom.. Astrid. Medford, OR. Tue Jun 20 2017
