12 x 20 ft Inground Pool Winter Covers

A 12 x 20 ft inground pool takes a 17 x 25 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 12 x 20 ft inground pool?

A 17 x 25 ft cover. That is the pool plus 5 ft, which leaves 2.5 ft of overlap on every side. Covers cut for larger pools that still leave enough overlap are grouped under Also fits.

How many water tubes does a 12 x 20 ft pool need?

The 17 x 25 ft cover has an 84 ft edge, so 11 tubes of 8 ft, or 9 of 10 ft. Lay them end to end around the outside of the cover, where they rest on the deck rather than on the water.

Can I use a cover made for a bigger pool on a 12 x 20 ft pool?

Yes, as long as every side keeps 2.5 to 5 ft of overlap. A 17 x 29 ft cover leaves 2.5 ft on the sides and 4.5 ft on the ends. A 22 x 30 ft cover leaves the full 5 ft all round. Both are under Also fits.

Is there a mesh cover for a 12 x 20 ft pool?

Yes. The mesh cover drains rain and snowmelt straight through into the pool, so nothing collects on top and there is no pump to run. The solid covers on this page block the light instead, so the water opens cleaner in spring.

What are these covers made of, and how long are they warranted?

Triple laminated polyethylene with heat sealed seams, black on tan or silver on black. Stated warranties at this size run from 8 to 25 years, and each card lists its own.
