Acrylic Acrylic's hardness and high gloss make it very easy to clean Acrylic is seamless and virtually non-porous, making it less susceptible to mildew, soap scum, and other chemicals Since acrylic's color goes through the entire material, most scratches can be buffed out easily Acrylic is color fast and will retain its high-gloss appearance for many years Acrylic's finished side never touches the tub mold during the molding process, so its finish is protected from the beginning Acrylic provides high heat retention for a more comfortable bathing experience
