8 Best Inground Pool Covers for Winter (October 2026)
The best winter covers for inground pools include the Blue Wave Arctic Armor 20 x 40 ft Inground Cover for included fastening hardware, the Robelle 20 x 40 ft Super Winter Inground Cover for extra overlap, and the Navy Blue 25 x 45 ft Inground Winter Cover for a 25 x 45 ft pool.
On this page (5 sections)
The Blue Wave Arctic Armor 20 x 40 ft Inground Cover is the best inground pool cover for winter for a standard 20 x 40 ft rectangle, with a cable and winch included and water tube loops around the edge. Robelle is a close fit if you want a 5 ft overlap, while the TIXANF covers suit smaller 18 x 36 ft and 16 x 32 ft pools.
Measure the pool before comparing covers. A stated pool fit and the cover's actual dimensions are different, and built-in steps or an irregular shape can need extra material.

How we chose these inground pool covers for winter
The best fit depends on pool dimensions, overlap, fabric details and how the cover attaches around the edge. We compared the listed materials, fastening features, fit guidance and warranty information against the needs of a seasonal inground pool closing.
We gave more weight to clear pool sizing and specific installation details. Our score weighs specs, features and buyer feedback against what you're shopping for.

The best inground pool covers for winter
The Blue Wave and Robelle options lead this group for their stated 20 x 40 ft fit and more complete fastening details. The remaining picks serve larger or smaller pool sizes, or offer a different way to secure the perimeter.
Blue Wave Arctic Armor 20 x 40 ft Inground Cover: Best for included fastening hardware
- 7 x 7 scrim woven polyethylene
- Heat-sealed seams
- Sewn water tube loops every 4 ft
- Cable and metal winch included
The cable and metal winch come with the cover, and sewn loops every 4 ft provide a separate way to secure water tubes. Its black underside blocks sunlight to help inhibit dirt buildup.
Pros
- Cable and metal winch included
- Water tube loops every 4 ft
- Black underside blocks sunlight
Cons
- Water tubes sold separately
- Not designed for foot traffic
Blue Wave's Arctic Armor suits a 20 x 40 ft rectangular pool where you want the cable and winch included. Its 7 x 7 scrim woven polyethylene has heat-sealed seams, and the black underside blocks sunlight to help inhibit dirt buildup.
Sewn loops every 4 ft give you another fastening option with water tubes, which are sold separately. The cover also has grommets every 2 ft for the included vinyl-coated cable and metal winch, so check which method fits your deck and closing routine.
Blue Wave backs the cover with an 8-year limited warranty, with full coverage in year 1 and prorated coverage in years 2 through 8. After heavy snow, the care guidance is to clear buildup from the pool edge with a soft-bristle broom; a pump can remove standing water.
This is a debris cover, not a safety cover. Never walk on it or let it support weight.
Robelle 20 x 40 ft Super Winter Inground Cover: Best for extra overlap
- 8 x 8 scrim polyethylene
- 2.36 oz per sq yd material
- 5 ft overlap
- Water tube loops
The 5 ft overlap gives extra material beyond a 20 x 40 ft pool. Robelle recommends water tubes as the only installation method, and says the cover should float loosely on the water.
Pros
- 5 ft overlap
- 8 x 8 scrim
- 10-year warranty
Cons
- Water tubes sold separately
- Water tubes are the recommended installation method
Robelle's Super Winter Cover is a strong match when the pool is 20 x 40 ft and you want more overlap. The cover measures 25 x 45 ft, giving it a 5 ft overlap beyond the stated pool size.
The material is heavy-duty polyethylene at 2.36 oz per sq yd, woven with an 8 x 8 scrim. Water tube loops run around the perimeter, and Robelle recommends vinyl water tubes as the only installation method; those tubes are sold separately.
Robelle says the cover should float loosely on the pool water without excessive stress. If steps or a buddy seat project beyond the pool, consider a larger size so the cover can reach around them.
The 10-year warranty is longer than the warranty stated for several other picks here. Choose this model if you are comfortable sourcing water tubes and following that floating installation method.
Navy Blue 25 x 45 ft Inground Winter Cover: Best for a 25 x 45 ft pool
- 7 x 7 scrim
- 4 ft overlap
- Heat-sealed seams
- Integrated loops and reinforced grommets
This cover is sized for a larger 25 x 45 ft rectangular pool, with a stated 4 ft overlap. Its heat-sealed seams and integrated securing points suit buyers who need a larger format.
Pros
- 25 x 45 ft size
- 4 ft overlap
- Heat-sealed seams
Cons
- Larger format may not suit smaller pools
- The product description gives limited detail on fastening hardware
Shop Square's navy cover is sized for a 25 x 45 ft rectangular pool, so it fills a gap for owners with a larger pool than the 20 x 40 ft options. It states a 4 ft overlap, a 7 x 7 scrim and heat-sealed seams.
The cover has integrated loops and reinforced grommets for securing it. The product information does not spell out whether cable, winch or water bags come with it, so confirm the fastening pieces you need before ordering.
This pick makes the most sense when your pool dimensions match the larger format. A cover that's too large or too small can make securing the edges harder, so measure the waterline and account for steps before choosing.
UIRWAY 20 x 40 ft Inground Winter Cover: Best for coated woven fabric
- Dual-layer LDPE coating
- 185 GSM fabric with 14 x 14 weaving
- 4 ft overlap
- 3-year warranty
UIRWAY pairs a dual-layer coating with tightly woven fabric and a 4 ft overlap. It advises sizing up for nonrectangular pools, built-in steps or uncertain measurements.
Pros
- 14 x 14 weaving
- 4 ft overlap
- 3-year warranty
Cons
- No cable and winch listed
- Check fit carefully around steps and irregular shapes
UIRWAY pairs a 20 x 40 ft rectangular pool fit with a stated 4 ft overlap. The cover's actual size is 44 x 24 ft, and the maker calls out 185 GSM fabric with 14 x 14 weaving and a dual-layer LDPE coating.
Rustproof aluminum grommets and wide PE webbing are the stated fastening features. UIRWAY says to size up for built-in steps, nonrectangular pools or uncertainty about dimensions, so verify the size chart and your pool shape before settling on this option.
A 3-year warranty is stated. Its combination of coated fabric and tight weaving makes it a reasonable alternative when those details matter more than included water tubes or a cable and winch.
In The Swim 20 x 40 ft Inground Winter Cover: Best for a cable and winch setup
- 7 x 7 woven polyethylene
- 5 ft overlap
- Cable and winch included
- Solid cover
The included cable and winch provide a familiar fastening setup for a rectangular pool. The stated 5 ft overlap adds material beyond the pool dimensions.
Pros
- Cable and winch included
- 5 ft overlap
- 7 x 7 woven material
Cons
- Product bullets conflict on whether it is for above-ground or inground pools
- Limited fit detail for irregular shapes
In The Swim's cover states a 20 x 40 ft rectangular fit, a 5 ft overlap and a cable and winch. Its 7 x 7 layered woven polyethylene is described as helping reduce chemical use and maintenance time.
There is a fit caveat to resolve before buying: one bullet describes protection for above-ground pools, while other details identify a rectangular inground pool fit. Confirm that this exact model is intended for your pool and installation before ordering.
If the intended inground fit is confirmed, the overlap and included fastening hardware make the setup comparable to other 20 x 40 ft options. Its product information doesn't give as much guidance for steps or irregular shapes as some competing picks.
Doheny's Economy 20 x 40 ft Winter Cover: Best for water bag loops
- 5 ft overlap
- Water bag loops about every 4 ft
- Aluminum grommets at all 4 corners
- 4-year economy cover
This economy cover has water bag loops about every 4 ft to help keep bags in place, plus corner grommets. Water bags are not included.
Pros
- Water bag loops around the perimeter
- 5 ft overlap
- Economy option
Cons
- Water bags sold separately
- The product information does not specify scrim count
Doheny's Economy cover fits a 20 x 40 ft rectangle and includes a 5 ft overlap. Its water bag loops about every 4 ft help keep bags in place, while aluminum grommets sit at all 4 corners.
The water bags are sold separately. The product information describes this as an economy grade, 4-year cover, but does not give a scrim count for this specific option.
Choose it if you already use water bags or want to buy them separately. Check the perimeter layout and the extra material around your pool before installation, especially near corners or decking.
Heavy Duty 18 x 36 ft Inground Winter Cover: Best for an 18 x 36 ft pool
- 12 x 12 mesh count
- 4 ft overlap
- Water bag straps
- Reinforced edges
The 18 x 36 ft size matches a smaller rectangle than the 20 x 40 ft picks. It uses water bag straps, and the water bags are not included.
Pros
- 18 x 36 ft size
- 12 x 12 mesh count
- 4 ft overlap
Cons
- Water bags sold separately
- Limited product details beyond the listed features
This TIXANF cover is sized for an 18 x 36 ft rectangular pool, a useful option when 20 x 40 ft would leave too much material. It states a 12 x 12 mesh count, reinforced edges and a 4 ft overlap.
Water bag straps secure the cover, but bags are not included. The cover is described as needing to lie flat against the water surface, so plan the water level and edge fastening together.
The product details also describe it as mesh while claiming to keep rain and snow out. Since those descriptions can point to different water behavior, confirm how the cover handles water before choosing it over a solid option.
Heavy Duty 16 x 32 ft Inground Winter Cover: Best for a 16 x 32 ft pool
- 12 x 12 mesh count
- 4 ft overlap
- Water bag straps
- Reinforced edges
This is the smallest stated pool fit in this group, at 16 x 32 ft. Its 4 ft overlap and water bag straps offer a straightforward setup when those dimensions match your pool.
Pros
- 16 x 32 ft size
- 12 x 12 mesh count
- 4 ft overlap
Cons
- Water bags sold separately
- Product dimensions differ between the stated size fields
The second TIXANF option fits a 16 x 32 ft rectangular pool and gives the same stated 4 ft overlap and 12 x 12 mesh count as its larger sibling. Water bag straps are included in the description, with bags sold separately.
Its product details conflict on dimensions: the title and bullets describe a 16 x 32 ft pool fit, while the size field gives a much smaller measurement. Confirm the actual cover dimensions and intended pool fit before buying.
Choose this cover only if the seller confirms the 16 x 32 ft fit for your pool. A size mismatch can leave parts of the pool exposed or make the cover difficult to secure.
What should you check before buying a winter cover?
Start with the pool's waterline dimensions, shape and any steps or seats that extend beyond the main rectangle. Then compare those measurements with both the stated pool fit and the cover's actual dimensions, including overlap.
Next, check how the edge is secured. Some covers use water tubes or bags that are sold separately, while Blue Wave and In The Swim include a cable and winch; the installation method should suit your pool surround.
Finally, decide how you'll handle water and debris through the winter. Solid covers can collect rain and snowmelt on top, so plan for a cover pump and regular checks.
Our guide to keeping water off a pool cover covers that routine.
Is a winter cover a safety cover?
No. A winter debris cover is meant to keep seasonal debris out of the pool, and it should not be treated as a barrier for people or pets.
Blue Wave specifically says not to walk on its cover or let it support weight.
If you need a cover designed to support foot traffic, compare the construction and intended use in our safety cover versus winter cover guide. Keep the distinction clear when choosing and installing a cover.
Which inground pool cover for winter should you choose?
Choose Blue Wave if you have a 20 x 40 ft rectangle and want both a cable and winch and water tube loops. Pick Robelle for the same pool size with a 5 ft overlap and a water-tube-only installation recommendation.
For a 25 x 45 ft pool, consider Shop Square's larger format; for a smaller rectangle, compare the TIXANF sizes and verify the conflicting dimensions first. Read how to measure your pool for a cover before ordering, then plan for removing standing water during winter.

Frequently asked questions
How much overlap should an inground pool cover have?
The right overlap depends on the cover's fastening method and your pool layout. The 20 x 40 ft covers here state overlaps from 4 to 5 ft, while UIRWAY gives a 4 ft overlap and advises sizing up for steps or irregular shapes.
Measure the pool and compare the actual cover dimensions before buying.
Should a winter pool cover be solid or mesh?
A solid cover blocks water from passing through, so rain and meltwater can collect on top and may need pumping. Mesh lets water drain through, but fine debris can still enter the pool.
Read our guide to mesh and solid pool covers to compare cleanup and water management.
Can you walk on an inground winter cover?
No. A winter debris cover is not a safety cover and should not support a person’s weight.
Blue Wave explicitly warns against walking on its cover.
If you need a barrier designed for foot traffic, compare the differences in our safety cover versus winter cover guide.
How do you keep water off a solid winter pool cover?
Use a cover pump to remove standing water from a solid cover after rain or snowmelt. Check the pump and cover regularly, because pooled water adds weight and can complicate winter maintenance.
See our guide to keeping water off a pool cover for practical options.
