Unrippable Winter Cover for 25x45ft Rectangle In-Ground Pool

You absolutely need to know the size of your in-ground pool. Measure your pool from the inside edge to the inside edge to get the exact length and width (for oval or rectangular pools) or the diameter (for round pools). If you have steps, or swimouts, etc. that extend the length of width from the main part of the pool add those dimension to your overall LxW. If you have an irregular shaped pool (kidney, custom), then you will need to imagine the largest rectangle that will completely cover the pool and that will be your LxW. The LxW that you have is your Pool Size and you need to remember it.

Winter covers are sold based on your pool's size, not the cover's actual dimensions. The cover is usually 4-5ft longer and wider than the pool. This usually allows enough cover to float on top of the water in the pool, come up the sides, and have at least 12 inches (1ft ) of the cover to lay flat on the deck and be held in place with water tubes. This is called the overlap.

Now you can search for a pool cover that is made for the Pool size you have. If there is not one for the your exact pool size, then find the next pool size that is larger. EX: if your pool is a 16x32ft pool and doesn't have extra pool steps extending either the length or width, then you will look for winter pool covers for a 16x32ft pool. Now if you have steps on the end of the pool that extends the water past the 16x32ft rectangular shape of your pool by 3ft, then your pool size is now a 16x35ft pool. The next standard pool size they usually make a winter pool cover is 18x36ft and this becomes the cover you should get for your pool. Any extra cover material on top of the deck can be folded up and under the water tubes for a neat and tidy appearance.

Standard covers use cheap fillers in their inner woven material (scrim) that degrade and tear easily. Unrippable versions use solid polyethylene strands with thick UV-stabilized coatings designed to withstand extreme cold and high winds without ripping. It is so very strong, its nearly impossible to rip where in the video test, the standard covers ripped easily. The warranty is arguably the BEST in the industry: 8-Year Full Non-Prorated Warranty.

The cover's core scrim (inner woven layer) is made from 100% pure polyethylene with no cheap fillers or regrind material. Freetime Fun states this makes it up to five times stronger than covers that rely on high weave/scrim counts, which they say can be misleading since those covers often use weaker filler-based tapes.

Yes, a cover pump is recommended. Solid winter pool covers are waterproof, unlike a mesh cover, so rain and melting snow sit on top of it instead of draining through. Industry guidance for this type of cover is to remove standing water once it exceeds about an inch deep, since heavier accumulation can stress the seams and pull the cover into the pool. A small electric submersible pump,or periodical siphoning, is the typical recommendation, and letting water sit unpumped for long stretches can shorten the cover's lifespan and complicate removal in spring.

The Unrippable Winter Cover uses a super-strong scrim made from 100% polyethylene flat wide strips that full width coverage instead of space out thread with cheap fillers. This scrim is engineered to be up to five times stronger than typical winter covers, so it greatly resists tearing from wind, ice, and normal handling during the off-season.
