Master Spas Covers
Owning a properly-sized Master Spa hot tub cover is best way to keep the heat in, the cold out, and your energy bills low! As heat rises from your spa, a well-insulated cover will act as a barrier and prevent the heat from escaping.
Our covers contain a 1.5lb foam density, long steam stopper cushions, six-inch foam insulation, and four inch tapered sides. All of these elements ensure that your hot tub is as energy efficient as can be! Want a completely custom hot tub cover? We can do that too!
