25 x 40 ft Inground Pool Winter Covers

A 25 x 40 ft inground pool takes a 30 x 45 ft cover. The extra is the overlap, 2.5 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.

Inground winter cover questions

What size winter cover fits a 25 x 40 ft inground pool?

A 30 x 45 ft cover. That is the pool plus 5 ft, which leaves 2.5 ft of overlap on every side for the water tubes to sit on.

How many water tubes does a 25 x 40 ft pool need?

19 tubes of 8 ft, or 15 of 10 ft. The 30 x 45 ft cover has a 150 ft edge, and the tubes go end to end around it.

Which larger covers also fit a 25 x 40 ft pool?

A 30 x 46 ft cover leaves 2.5 ft on the sides and 3 ft on the ends. A 30 x 50 ft leaves 2.5 ft on the sides and 5 ft on the ends. Both are under Also fits.

My pool is 24 x 40 ft. Can I use a 30 x 45 ft cover?

Yes. On a 24 x 40 ft pool it leaves 3 ft on the sides and 2.5 ft on the ends, which is inside the 2.5 to 5 ft the overlap has to keep. The 24 x 40 ft page shows it the same way, under Also fits.

Do I drain the pool for the winter?

No. Never drain an inground pool. The water holds the shell down against the groundwater outside it. The level comes down a little, and the cover's overlap is cut to reach the lowered waterline and still lap onto the deck.
