Wesiti 5 ft Solar Pool Cover Discs — 16 mil, 6-Pack Circular Heating Blankets for Pools, Spas & Hot Tubs

Wesiti 5 ft Solar Pool Cover is a 16-mil, 6-piece set of circular solar blankets designed to float on water and help retain heat, reduce evaporation and keep debris out of pools, hot tubs and spas.

These lightweight, bubble-style covers are intended for above-ground and inground circular pools, spas and hot tubs where small, modular discs give flexible coverage. Each disc measures about 5 ft (1.5 m) in diameter and the 16-mil construction provides a durable barrier that floats with the bulb side facing down into the water. Sold as a six-piece pack, they’re meant to be combined to cover larger surfaces, cut heat loss, and slow evaporation without the bulk of a single full-sheet cover.

How do these solar discs help keep pool water warmer?

The bubble-layer design traps solar energy and reduces heat transfer from water to air, helping maintain a warmer surface temperature. They act as a thermal barrier overnight and during cooler days, letting sunlight in while minimizing conductive heat loss.

• 16-mil thickness for stronger insulation than thin film covers
• Bubble-side down increases heat capture and flotation
• Individual discs can be arranged to maximize sun exposure
• Reflective top surface helps convert sunlight to warmth

Will these covers reduce water evaporation and debris?

Yes — by forming a floating layer they limit direct water exposure to air, which slows evaporation and reduces the rate of chemical loss. The discs also intercept leaves, pollen and light debris, keeping pool water cleaner between full covers or maintenance.

• Reduce water loss by limiting exposed surface area
• Catch surface debris to ease skimming and filtering
• Help preserve pool chemicals by minimizing off-gassing
• Simple to place and remove for routine cleaning

How do I use and arrange the Wesiti solar pool discs?

Place the bubble (bulb) side down so the smooth side faces up and allow each disc to float freely. Cover as much of the surface as possible—performance improves when roughly four-fifths or more of the pool surface is covered. Discs can be overlapped slightly and rearranged to match irregular or circular shapes.

• Bulb side down on water for correct flotation and heat transfer
• Calculate pool surface and aim for ≥80% coverage for best effect
• Six 5 ft (1.5 m) discs per pack for flexible coverage options
• Trim is possible for custom fit on odd-shaped areas

Are these discs compatible with different pool types and sizes?

The discs are versatile for most circular, irregular, above-ground and inground pools, as well as hot tubs and spas. Because each unit is separate, you can scale coverage by adding more packs or arranging the discs to fit curved edges and elevated rims.

• Works with above-ground, inground and irregular-shaped pools
• Suitable for hot tubs and small spa surfaces
• Modular design adapts to curved and segmented pool sections
• Durable materials resist tearing and deformation during use

Who is this for: Homeowners and renters with small-to-medium pools, hot tub owners, and caretakers of irregular or round pool shapes who want an easy, removable thermal solution. It’s a practical accessory for anyone seeking to limit evaporation, reduce heating time, and cut down on surface debris with a lightweight, stackable solar option that’s simple to position and remove.
