American Tubs Extra Wide Series Model 3555 Walk-In Bath Tub

The American Tubs D3555KS Extra Wide Walk-In Tub is the most spacious model in our entire lineup—designed to deliver a safe, accessible, and luxurious bathing experience for users up to 400 lbs. Engineered for comfort, this extra-large walk-in bathtub features a generous 28¾” ADA-compliant contoured seat and the widest interior well space available in a walk-in tub today, making it a top choice for bariatric users and multi-generational households.

The 23½” curved, easy-access door enhances entry and exit, while the integrated under-seat support frame ensures long-term durability. Ideal for users who enjoy a spacious soak or need room for assisted bathing, this walk-in bath is also popular among those who prefer to use it as a standing shower.

Due to its size, it's important to verify hallway, doorway, and stairwell dimensions prior to installation, and to ensure your home’s water heater can support its larger water capacity. The D3555KS offers unmatched comfort, safety, and accessibility in a generously sized footprint.
