4.2ft Inflatable PVC Hot Tub Cover — Insulated Energy-Saving Lid, Rain & Debris Protection for Yard/Garden

Fit and compatibility: Designed for rectangular hot tubs with a 4.2 feet diameter, this inflatable spa cover works with most of our spa hot tub series and is ideal for outdoor use in the yard or garden. Quick setup: The blow-up bathtub cover inflates rapidly and is ready in minutes, making it simple to deploy when you want to keep your tub clean and warm. Robust PVC construction: Built from premium PVC, the cover is strong, durable, and resistant to wear and scratches for long service life. It also helps block objects from entering the water and reduces the frequency of filter use. Superior protection: This energy-saving lid keeps out wild animals, leaves and other debris, limits dust intrusion, minimizes condensation, and helps prevent freezing — all of which cut down on routine filter cleaning. Thermal performance: The inflatable protector reduces water evaporation and heat loss, captures sunlight to help maintain temperature, and shortens the time needed to reheat the water for use.
