Smartline 20 Ft X 40 Ft Rectangle Liner
The Smartline liner is a beaded, 20-gauge virgin vinyl option designed for rectangular, flat-bottom pools. It is important to verify pool measurements, especially wall height, to ensure an accurate fit. North American cut material is hand-folded to minimize creasing. For installation, allow the liner to warm in sun for about an hour to improve stretch. Ideal installation temperatures are around 70–80°F. This model fits pools with a 48-inch flat-bottom and uses the standard bead section atop the liner material to snap into the bead receiver opening. Always confirm wall height and bead compatibility before purchasing.

It reduces water evaporation by up to 95% and can raise water temperatures by 8–15°C, depending on conditions. The cover is designed for both inground and above-ground pools and works best in environments with chlorine levels below 2.5 ppm and pH above 7.2. It’s a practical accessory for extending the swimming season and lowering heating costs through solar gain.

Real Relax Solar Pool Cover, 20×40 Ft
This 16 mil blue solar pool blanket uses bubble technology to minimize evaporation and heat loss while absorbing solar energy to warm the pool water. It is designed to cover a 20×40 foot rectangle and helps keep debris out of the pool when not in use. Regular use can contribute to lower heating costs and a longer swimming season, especially in milder climates.
WaterWarden Inground Pool Safety Cover 20×40

Buying Guide: Key Purchase Considerations For 20×40 Inground Pools
When choosing products for a 20 x 40 inground pool, consider these factors to balance performance, safety, and value:
- Pool type and liner fit: Verify wall height and bead style. Beaded liners require bead receivers and precise measurements. Ensure the liner is designed for a 48-inch flat bottom if applicable and confirm your pool’s exact dimensions before ordering.
- Material quality and thickness: Liner thickness (gauge) affects durability and lifespan. Virgin vinyl is generally more resistant to tears and UV damage than recycled materials. For beaded or overlap installations, match the liner’s construction to your pool’s construction and preferred installation method.
- Installation temperature and handling: Some liners benefit from warm temperatures during installation, with recommendations to lay the material out in the sun to soften. Follow manufacturer guidance to minimize wrinkles and ensure proper stretching.
- Safety and weather protection: For safety covers, look for triple-stitched seams, reinforced straps, and included installation hardware. UL or ASTM certifications add an extra layer of assurance for pool safety and durability.
- Energy savings and seasonal use: Solar pool covers can reduce evaporation, conserve heat, and extend the swimming season. Consider climate, sun exposure, and pool usage when evaluating cost savings and temperature gains.
- Warranty and support: Check warranty length and coverage for liners and safety covers. A robust warranty reflects manufacturer confidence and can influence long-term maintenance costs.
- Installation complexity: Some products include complete installation kits, while others may require professional installation. Assess your DIY comfort level and available tools before purchasing.
- Compatibility with accessories: Ensure that safety covers accommodate the pool’s deck layout and that installation hardware aligns with your deck, anchors, and springs.
- Maintenance needs: Covers and liners affect pool maintenance routines, including cleaning, chemical balance, and winterization steps. Plan for regular inspection of seams, beads, and anchor points.
