Additional Details ------------------------------ Product description: Amazon.com Fitting the soft mat of this unit into any bathtub by running the flexible hose from the control unit into the water instantly converts the tub into a bubble-massage spa. The 47-by-14-inch mat, made of PVC plastic, adheres firmly to the tub with suction cups and fills with air to cushion the body. The 14-foot hose, which attaches to the tub with a suction cup, delivers bubbles on command with 600 watts of power. Using either the LED-illuminated touch pad on the control unit or the cordless remote control, massage duration can be selected (15, 30, or 60 minutes) as well as the massage strength (high, medium, or low), the bubble speed (high, medium, or low), and either steady bubbles or one of three variable bubble patterns. The water-resistant remote control operates with two 3-volt batteries (which are included) and fits into a holder that adheres to wall or tub with a suction cup. The control unit's power cord is 14 feet long. The spa carries a two-year warranty against defects. --Fred Brack
