HYDROSPRING Spas made with Lucite ® cast acrylic have always been the easiest to clean. Genuine Lucite® spa surfaces allow you to realize your visions in deep, breathtaking colours. Choose from a wide range of colours finishes to fit any decor--from stunning, textured granite to smooth, elegant marble styles. Lucite® cast acrylic has color that runs true to the core of the material. With proper care, your hot tub will be as rich and lustrous years from now as it is today. Now Lucite International has taken Lucite® acrylic surfaces to the next level by incorporating Microban® antimicrobial product protection which inhibits the growth of bacteria that can cause odor, stains and product degradation. And Microban® won't wear off with time because it's actually built in the hot tub spa's surface.
