Fortunately for you, any quality hot tub will come with an insulated cover. The cover is actually one of the most important components of the hot tub. The cover holds the heat in so that your energy bills stay low. All quality hot tub covers also have safety locks to keep small children out when not accompanied by an adult. Not all hot tub covers are made the same. You want to make certain that the hot tub that you get has a high quality, thick foam insulation core with a good seal to hold the heat in the tub when it is not in use. Along with the cover, you will want to make sure you get a high quality, easy to use, cover lifting device; this will help you to easily lift the cover on and off when you do want to use the hot tub.
