The acrylic provides color, not structure. We measure durability by weight and the thickness of the fiberglass, not thickness of the acrylic. The acrylic covering is at most 1/8 inch thick and tapers to 15 or 20 thousandths of an inch in the footwell of the spa. Water is heavy. Water in a spa can weigh one or two tons. What happens when you fill a thin-walled spa with water? The water pushes down and gradually bends or breaks the spa. To compensate for the lack of strength in a thin-walled spa, some manufacturers fill the underside with urethane foam. Others require sand or a wood structure underneath the spa. Sand or foam provides support under the benches or seats, lounge area and step. Portable spas depend on the wooden skirt and total foam fill to support the water weight. Unfortunately servicing plumbing leak is nearly impossible. Just look at Craigs List. There are thousands of these leakers for sale.
