Gekufa Hot Tub Solar Bubble Blanket 7x7 ft 16-mil Gray — Heavy-Duty Thermal Pool Cover for Heat Retention & Evaporation Control

The Gekufa Hot Tub Bubble Blanket is a 7 x 7 ft, 16-mil square solar cover designed to float on spas and small pools to retain heat, reduce evaporation and protect water when not in use.

This heavy-duty, gray thermal blanket uses a bubble-core polyethylene construction to capture solar energy and slow heat loss overnight. Lightweight yet durable, the 16-mil sheet can be trimmed to match custom tubs, above-ground frames, or irregular spa shapes. It’s intended as a mechanical insulator and solar absorber — a low-effort accessory that helps keep water warmer between heating cycles and cuts evaporation so you waste less water and energy.

How does the Gekufa bubble blanket conserve heat for my hot tub?

The bubble structure traps pockets of warm air and transfers sunlight into the water surface, reducing radiant and convective heat loss. Placing the cover on the water creates a barrier that slows cooling overnight and between uses.

• 16-mil PE construction resists tearing and UV fade
• Bubble cell design captures and holds solar warmth
• Reduces heat loss across the water-air interface
• Floats directly on the water for immediate effect

Will this solar cover fit my pool or spa and how easy is it to customize?

The 7 x 7 ft square is a convenient starting size for many small hot tubs and plunge pools, and the material is designed to be cut to fit. Scissors or a utility knife let you trim the edges so the cover conforms to odd shapes or frames without special tools.

• Can be cut to shape for round, oval, or custom tubs
• Lightweight for straightforward positioning and removal
• No special hem or hardware required for simple trims
• Large enough for many compact above-ground pools and spas

How does the Gekufa blanket help with evaporation and cleanliness?

By covering the water surface, the blanket dramatically reduces direct evaporation and limits airborne debris from entering the water. Less evaporation means lower water top-up frequency, and fewer leaves and dirt result in easier maintenance.

• Blocks wind-driven evaporation and conserves water
• Acts as a physical barrier against leaves and dust
• Helps keep chemical balances steadier between uses
• Simplifies pool clean-up and reduces strain on filtration

How durable is the material and what care does it require?

Made from robust PE material, the 16-mil sheet resists daily sun exposure and repeated wetting without rapid degradation. Routine rinsing and storing the blanket out of harsh weather will extend its usable life.

• PE composition resists fading, cracking and soaking damage
• Can be reused season after season with basic care
• Simple cleaning: rinse, dry, and roll for storage
• Avoid sharp objects and rough surfaces to prevent punctures

Who is this for? The Gekufa Hot Tub Bubble Blanket is ideal for hot tub and small pool owners who want an affordable, low-effort way to keep water warmer, lower evaporation, and reduce maintenance. It suits backyard spa users, seasonal pool owners, and anyone with above-ground or framed pools who prefers a cover that’s simple to trim, apply, and store. This product is not a safety cover; it’s intended for insulation, solar heating assistance, and debris reduction rather than child or pet protection. If you want a lightweight, customizable solar solution that minimizes water and energy waste, this Gekufa blanket is a practical choice.
