Sundance Spas offers a variety of Acrylic Shell colors for you to choose from. With most models, you can choose any color, although with some models, there may be some exclusions (usually because of the size of the hot tub). A few colors are textured, while many are smooth. Functionally there is little difference, and it's entirely personal preference.
Colors may appear different from screen to screen. We try to have most of the shell colors represented in our showroom and at the very minimum we have color samples available to see in person. It is also worth nothing that colors with marbling can have variances in the marbling from hot tub to hot tub.
