Angooni Hot Tub Thermal Blanket 8x8FT (244x244cm) 16MIL Bubble Cover — Insulating, Trim-to-Fit

Angooni's 8x8FT 16MIL hot tub thermal blanket is a durable bubble cover designed to reduce evaporation and trap solar heat, floating on the spa surface for easier warming and lower maintenance.

This 244 x 244 cm bubble blanket from Angooni is made with a thicker 16MIL construction to resist tearing and preserve the integrity of the air bubbles that store and transfer heat. Engineered to sit bubble-side down on the water, the cover serves as an insulating layer that limits heat loss, blocks debris, and shortens the time your heater needs to run. It’s also simple to trim for a custom fit, making it compatible with in-ground spas, portable hot tubs, and stock-tank pools.

How does the thermal blanket reduce heat loss and evaporation?

The Angooni blanket creates a barrier between the water and air that slows evaporation and heat escape. Air trapped in the bubbles adds insulating capacity, while the material’s solar-transmissive surface helps capture sunlight and pass warmth into the water.

• 16MIL thickness for improved durability and fewer punctures
• Bubble layer holds air to limit convective heat transfer
• Designed to float bubble-side down for best heat transfer
• Reduces water evaporation—lower refill frequency and chemical use

Will this cover fit my hot tub and how easy is it to customize?

The blanket ships as an 8x8 foot (244x244 cm) sheet that can be trimmed with scissors to match non-standard tubs. Because it’s flexible and lightweight, most owners can cut it to shape and lay it in place without tools.

• Pre-cut size: 8x8 feet for many square and nearly square tubs
• Trim-to-fit design lets you adjust for round, oval, or odd-shaped tubs
• Bubble side should face down when installed for optimal performance
• Warning: measure your tub before ordering to ensure best fit

How does the Angooni blanket protect water quality and reduce upkeep?

By covering the water surface, the blanket keeps leaves, dust, and small pests out of the tub, reducing skimming and filter strain. Less surface exposure also helps keep chemicals and temperature more stable, cutting routine maintenance time.

• Blocks debris like leaves, dirt, and small animals
• Reduces frequency of topping off water and chemical adjustments
• Lightweight cover is easy to remove and replace for cleaning
• Compatible with spas, stock tanks, and small pools

How durable is the 16MIL material compared with typical covers?

The Angooni blanket’s 16MIL gauge exceeds common 8–12 MIL options, offering stronger puncture resistance and longer bubble life. That extra thickness helps prevent premature tearing and maintains insulating performance across more seasons.

• Thicker film resists abrasion and punctures better than thinner blankets
• Air bubbles less likely to burst, preserving insulating function
• Longer usable life reduces replacement frequency and cost
• Store flat or rolled to avoid creasing when not in use

Who this is for: The Angooni 8x8FT 16MIL hot tub thermal blanket is best for spa and small pool owners who want a low-cost, easy-to-use insulation layer that cuts evaporation, keeps debris out, and leverages sunlight to warm water. It fits users who prefer a lightweight, trim-to-fit solution rather than a rigid hard cover, and who want a thicker, longer-lasting bubble blanket than typical market options.
