A Signature Spa’s marine-grade vinyl hot tub cover adds to the value of your spa. Every high-density foam hot tub cover is made for maximum heat retention. The Spa Cover locks into place forming a protective seal to keep heat in and weather out. Additionally, the spa water stays clean longer, reducing maintenance costs. Available in Light Grey or Mocha, each hot tub spa cover coordinates with the acrylic spa shells and cabinets. They taper from 4″ to 2″ center-to-side for efficient water run-off, with handles both inside and outside the spa cover for easy lifting and closing.
