If you want a totally relaxing bath to soothe your tired muscles and relieve stress, then invest in air bathtubs. This type of tub is not known to give therapeutic water massage. But the air that goes through the jets and into the tub creates a gentle, soothing massaging action to provide general relaxation.

But this tub is flexible which makes it a perfect replacement for any modern bathroom. You can order from online retailers a customize version, such as combining jets that can create a whirlpool bath. Prices for customized air bathtubs may vary depending on their features, styles, materials and designs. Here is a review of online offerings.
