18 x 36 ft Inground Pool Winter Covers
A 18 x 36 ft inground pool takes a 23 x 41 ft or 24 x 42 ft cover. The extra is the overlap, 2.5 or 3 ft on every side, and it laps onto the deck where the water tubes hold it down. Every cover on this page is listed by the pool it fits, and the covers cut for a larger pool that still work here are under Also fits.

These are cut for a larger pool but still work here. Each card shows the overlap it leaves on the sides and on the ends, so you can check it against your deck.

Email me when it is backInground winter cover questions
What size winter cover fits an 18 x 36 ft inground pool?
A 23 x 41 ft cover, or a 24 x 42 ft from the Cool Covers King line. Plus 5 ft leaves 2.5 ft of overlap a side, plus 6 ft leaves 3 ft.
How many water tubes does an 18 x 36 ft pool need?
16 tubes of 8 ft, or 13 of 10 ft. The 23 x 41 ft cover has a 128 ft edge, and the tubes go end to end around it, out on the deck.
Which larger covers also fit an 18 x 36 ft pool?
A 23 x 45 ft cover leaves 2.5 ft on the sides and 4.5 ft on the ends. A 25 x 45 ft leaves 3.5 ft and 4.5 ft, and a 26 x 46 ft leaves 4 ft and 5 ft. All are listed under Also fits.
Is there a leaf net for an 18 x 36 ft pool?
Yes. A leaf net lies over the solid cover and holds the leaves off it. Once the trees are bare you pull the net off with the leaves still in it, instead of scooping them off the cover.
Solid or mesh for an 18 x 36 ft pool?
Both are on this page. Solid keeps the light out, so the water opens cleaner, and you pump the rain and snowmelt off the top. Mesh drains straight through into the pool, so nothing collects, and you do more cleaning in the spring.
