Sterling Plumbing has expanded its Lawson bath collection with the Lawson Air Massage bath. The 20-inch-deep bath features three levels of airflow with 360 degrees of bubbles. The blower automatically purges all water from the air channels 20 minutes after the bath has drained, which allows for less maintenance than a traditional whirlpool. Baths are made of Vikrell material, a solid, lightweight, durable material that is scratch- and stain-resistant. Heating is optional and three colors are available: almond, biscuit and white.
