13FibroTherapy-tbBullfrog is the industry leader in green spa technology. It all starts with the design of their spas, which are made with recyclable ABS plastic and synthetic wood for an upscale finish. Bullfrog spas do not use real wood, which can warp, rot, and spring leaks, resulting in expensive repair bills. If you’re worried about having to use potentially harmful chemicals to retard bacteria growth, don’t be—Bullfrog spas filter 100 percent of the water within them, saving you time and allowing you to keep chemical usage to a minimum.
