Hot Tub Bubble Blanket 7x7 FT 16-Mil Solar Cover - Retains Heat

Our review of the Hot Tub Bubble Blanket finds it best suited for hot tub and small pool owners who want a low-cost, straightforward way to retain heat and cut evaporation. The biggest reason to buy is its simple, effective thermal action: the 16-mil PE material holds warmth and reduces water loss so tubs heat faster and stay warm longer. Installation is easy and the cover can be cut to fit irregular shapes, making it a practical choice for seasonal use or as a backup to heavier covers.

Key Features

• Energy Saving: Uses sunlight to gently heat water and helps retain heat so you spend less on reheating and maintain swim-ready temperatures.
• Evaporation Reduction: Cuts water evaporation by up to 95%, which saves water and reduces the need to refill or rebalance chemicals frequently.
• Durable PE Material: Constructed from strong, lightweight PE that resists fading and damage from sun and water exposure for seasonal reuse.
• Custom Fit: Can be trimmed to size with scissors so it adapts to different hot tub shapes and small pools without special tools.
• Wide Application: Works with hot tubs, spas, ponds and above- or in-ground pools as a simple insulating layer and debris barrier.
• Risk-Free Purchase: Backed by a 100% satisfaction guarantee, letting buyers test performance with support if expectations are not met.

Who It's For

This cover is aimed at homeowners with small pools, inflatable or metal-frame round pools, and hot tub owners who want an inexpensive way to reduce heating costs and water loss. It is especially useful for those who need a lightweight, easy-to-handle solution that can be cut to fit odd shapes and stored between uses.

It is less appropriate for someone seeking a permanent, heavy-duty winter cover or a rigid safety cover; those requiring extreme longevity under heavy use should consider thicker, specialized insulation options. Users expecting a multi-year commercial-grade life should weigh mixed durability reports before relying on it as the sole long-term cover.
