3 Things to Know About Covers for Irregular-Shaped Pools

Custom covers are the only safe option Irregular pools like kidney, freeform, or lazy-L shapes have curves that standard covers cannot hug. Gaps let in debris and create a safety hazard, since a loose cover can allow someone to slip under.

Measure the widest and longest points Get exact dimensions of your pool at its extremes, then order from a manufacturer that makes custom covers. Many pool supply stores offer this service, though you will pay more and wait one to two weeks.

Tarps are a poor substitute A heavy tarp with water bags can work temporarily for winter storage if safety is not a concern. But it will still let in leaves and look sloppy, so the extra cost for a custom cover is worth it.
