—Design decisions
Choosing a cover for a new pool
Covers reduce debris, evaporation and temperature swings. Some must be planned into the pool’s design from the start.
Automatic slatted covers roll out over the water from a box built into the pool or deck. They suit rectangular pools, keep debris out and reduce evaporation, and can help hold temperature. Because the cover box is built into the structure, the decision must be made at design stage. Manual covers are simpler but need handling each time.
Design guides set out the choices that are hard to change once the shell is built.
Safety covers are designed to bear weight and form a barrier when closed. Solar covers — floating sheets — reduce evaporation and can gain some heat, useful in winter. Each type has different maintenance and storage needs. Choosing during design means fixings, cover boxes and power can be planned.
01Summary
What matters most here
Plan automatic covers early
The box is built into the pool.
Reduce evaporation
Covers save water.
Help temperature
Hold heat in winter, reduce gain in summer when shaded.

How to use this
Decide on the cover type at the design stage, especially for automatic slatted covers that need a box built into the pool or deck. Compare options on how they suit the pool’s shape, their safety, how much they reduce evaporation and heat change, and how they are stored and operated, so the cover is used rather than left in its box.
Mistakes worth avoiding
- Deciding after construction
- Some covers need structural provision built into the shell or deck. Choosing afterwards may rule them out or mean costly changes.
- Ignoring storage and handling
- A manual cover with nowhere convenient to store it tends not to be used. Plan where it goes when the pool is in use.
04FAQ
Common questions about this
- Do covers work on freeform pools?
- Automatic covers suit rectangular pools; other types can be shaped.
- Do covers keep the pool cool?
- They reduce evaporation; their effect on temperature depends on type and sun.
- Are covers a safety measure?
- Only covers designed to bear weight; others are not safety devices.
- Can a cover be added later?
- Surface-mounted covers can; built-in boxes need structural work.
