The bathtub is formed primarily from acrylic vacuum panels, which are then reinforced with fiberglass. This construction is more insulating and durable enough to withstand heavy blows without cracking or splintering. This bathtub is quite a high-quality Lucite acrylic and the acrylic is non-porous, which means it is more durable, retains heat longer, and is easier to clean. Because the tub's base is made of fiberglass, this tub tends to be lighter than other materials on the market. You can enjoy style and warmth while soaking in this polished oval tub, and its modern design is a good match for any look creating the perfect environment for you to bathe and immerse yourself in the spa experience.
