Oval 18ft x 33ft Solar Cover for Inground and Above Ground Pools

Our review of the oval 18' x 33' solar cover finds it best suited to pool owners who want a simple, effective way to keep water warmer and reduce evaporation without heavy equipment. The single biggest reason to buy is its proven ability to retain heat and lower overnight heat loss: the 12 mil thickness and bubble design absorb sunlight during the day and trap warmth after sundown. Installation is straightforward and the lightweight sheet makes daily use practical for one or two people maintaining a residential pool.

Key Features

• Optimal heat retention: The 12 mil thickness and bubble surface absorb sunlight and hold warmth overnight to help keep pool water comfortable.
• Prevents evaporation and debris: The cover reduces water loss from evaporation and blocks leaves and dirt, which lowers maintenance needs and chemical use.
• Lightweight and easy to use: The blanket is light enough to roll out and remove by hand, making daily covering and storage convenient for most owners.
• Durable construction: Heavy duty 12 mil material is designed for multiple seasons of use while remaining manageable to handle.
• Customizable fit: The oval cover can be trimmed with a marker and sharp scissors for pools with slightly different shapes, with bubbles facing down for best performance.
• Made in the USA: Manufactured domestically, which can matter to buyers seeking locally produced pool accessories.

Who It's For

This solar cover is a good match for owners of oval above ground or inground pools who want a cost-effective method to raise daytime temperatures and conserve heat overnight. It works well for seasonal pools where simple, repeatable installation is preferred over automated or rigid covers.

It is less suitable for those who need a fitted custom cover with straps or a winter safety cover rated for heavy loads; buyers expecting multi-year rugged commercial use should consider heavier commercial-grade options or reinforced covers made specifically for high-traffic installations.

Pros & Cons

Pros

• Effective heat retention thanks to 12 mil thickness and bubble design.
• Reduces evaporation and keeps debris out of the pool, cutting maintenance time.
• Lightweight and easy to handle for routine use and storage.
• Customizable trim lets it fit a variety of oval pool shapes.

Cons

• Durability receives mixed feedback; some users report it should last several seasons while others experienced wear earlier than expected.
• Not a safety or winter cover, so it will not replace rigid or anchored options for heavy-duty protection.
