American Tubs Compact Series Model 3138 Walk-In Bath Tub

Experience Comfort and Accessibility with the American Tubs Compact Series Model 3138 Walk-In Bath Tub

The American Tubs Compact Series Model 3138 Walk-In Bath Tub—also known as the “Cube Tub”—is a space-saving, high-quality walk-in bathtub designed for tight installations where traditional tubs won’t fit. This ultra-compact model, part of the Compact Series, is ideal for small spaces like three-quarter baths, 36” x 36” shower stalls, laundry rooms, or garages. It features an outward-swinging door and comes with two integrated side panels, offering flexibility for free-standing or alcove installations.

The D3138KW includes a Kingston one-piece faucet with a handheld sprayer, conveniently mounted on the tub deck. For those maintaining shower functionality, it pairs perfectly with an adjustable shower slide bar and custom shower curtain. Despite its smaller footprint, this walk-in tub delivers a premium bathing experience, making it the perfect compact walk-in bath solution for limited-space environments.
