The Water Brick Water Seat™ enhances the spa experience, adding comfort and an extra boost for those that need it. Made of PVC coated vinyl and a unique stuffing that holds its shape, the Water Brick is durable and well suited for the spa environment. At over 4″ thick, the water seat offers a great deal of comfort compared to sitting directly on a hard spa surface. To ensure the seat sinks into place, a removable pouch has been included which can be filled with marbles or washed pea-gravel. The spa experience is meant to be relaxing – let the Water Brick complete the experience. Available in blue and black.
