New from Covana is the Evolution, an automated cover built for hot tubs and swim spas. The cover fits square 7-foot and 8-foot hot tubs, rectangular 8-by-9 to 8-by-11-foot hot tubs, and round hot tubs up to 8 feet. Evolution covers are fully adjustable and can be raised within 20 seconds. The covers rise above the hot tub and are supported by four posts. The covers meet UL/CUL, CE and ASTM safety standards.
