Safety Tubs' latest model has lowered the threshold for its walk-in tubs, making it even easier for people with limited mobility to enjoy a relaxing bath. Sitting three inches off the ground, the unit features a 21-in. wide door and integrated 17-in. high seat. For a spa-like experience at home, amenities such as whirlpool and bubble jets, chromatherapy, aromatherapy, in-line heaters and self-cleaning technologies can be integrated. The compact 52 in. unit includes a built-in safety bar and slip-resistant floor. The tubs retail from $3,500 for a basic model to $7,500 for a fully loaded home-spa.
