Wesiti 5 ft Solar Pool Covers 16 mil — 3-Pack Circular Discs for Pools & Spas, Bubble-Insulated Heat Retention

Wesiti 5 ft 16 mil solar pool covers are circular, bubble-insulated discs sold as a three-piece kit to retain pool and spa heat, reduce evaporation, and extend swimming time.

These compact solar blankets are designed for above-ground, inground, and irregular-shaped pools, as well as hot tubs and spas. Each disc measures approximately 5 ft (1.5 m) in diameter and covers about 20 sq ft, providing a modular approach to covering awkward areas where a full blanket is impractical. Made from a durable 16 mil material, the covers use air-bubble insulation to trap warmth and slow water loss.

How does the Wesiti solar cover help warm my pool or spa?

The bubble layer captures sunlight and converts it into thermal energy that stays in the water, helping preserve daytime warmth into the evening. Using multiple discs lets you place coverage where heat loss is greatest without the expense of a full-size solar blanket.

• 16 mil thickness for better heat retention than thinner films
• Bubble side faces down to transfer sun-warmed air to the water
• Three 5 ft discs cover targeted zones totaling ~60 sq ft
• Modular placement for hot spots, steps, or spas

Will these covers reduce water evaporation and chemical loss?

Yes — covering the water surface significantly slows evaporation, which conserves water and helps maintain chemical balance. Partial coverage still yields measurable reduction in evaporation compared with an uncovered surface.

• Bubble barrier limits direct air exposure and wind-driven loss
• Reduces top-off frequency and chemical rebalancing needs
• Useful in windy or sunny climates where evaporation is common

How do I use and care for the 5 ft solar discs?

Place the covers bubble-side down onto the water so the bubbles make contact with the surface; this maximizes heat transfer. For best performance, cover at least 80% of your pool when possible and store the discs flat and shaded when not in use to prolong their life.

• Bubble side down in water; avoid dragging over rough edges
• Cover at least 80% of pool area for optimal results
• Rinse and dry before folding for storage to prevent mold
• Keep away from sharp objects and pool chemicals when stored

Are these covers compatible with different pool shapes and sizes?

Yes — the circular, modular format makes these discs ideal for irregular shapes and small areas where a full blanket won’t fit. They’re particularly handy for spas, round above-ground pools, and corners of larger pools.

• Works with inground and above-ground pools, spas, and hot tubs
• Three-piece kit allows flexible placement and partial coverage
• Great for covering steps, shallow ends, or sun-warmed zones

Who is this for: The Wesiti 5 ft solar cover three-pack is aimed at pool and spa owners who need a flexible, affordable way to retain heat and reduce evaporation without installing a custom full-coverage blanket. It's a practical choice for owners of small pools, hot tubs, irregular-shaped pools, or anyone wanting targeted thermal protection and water savings with easy storage and handling.
