There are several different types of walk-in tubs available today, and each is designed for different needs, uses and preferences. The main types of walk-in tubs are standard soaker walk-in tubs, deep enough for the user’s torso and lower body to submerge; hydrotherapy walk-in tubs, which feature massage jets; bariatric tubs, designed for larger users and support up to 600 lbs.; and wheelchair accessible walk-in tubs, also known as slide-in tubs. Add-on features are also available for most tub models from the majority of walk-in tub brands.
