Spa World Corp - Atlantis Tubs 4260VNAL Venetian 42x60x23 Inch Rectangular Air Jetted Bathtub - The Venetian series bathtubs resemble simplicity set in classic design. A rectangular, minimalism-inspired design turns simplicity of square forms into perfection of symmetry. An air pool bathtub creates thousands of warm bubbles that stimulate the skin&#039;s light touch receptors, producing an overall calming effect. An air blower works like a giant hair dryer, taking the room temperature air, increasing it by approximately 30-degrees and blowing it through the bath. Air baths differ from a whirlpool in that the massage is much softer. Drop-In tubs have a finished rim designed to drop into a deck or custom surround. They can be installed in a variety of ways like corners, peninsulas, islands, recesses or sunk into the floor. A drop in bath is supported from below and has a self rimming edge that is designed to sit over a frame topped with a tile or other water resistant material. The trim for the air or water jets is featured in white to color match the tub.
