Ultimate Charcoal Winter Oval Pool Cover 18 x 33 ft - Easy Install

In this review the Robelle Ultimate Charcoal Winter Oval Pool Cover is evaluated for owners of 18 x 33 ft above ground pools who need a tough, easy-to-install solid winter cover. The bottom line: this cover's extra 4 ft overlap and included winch and cable make installation noticeably simpler than standard covers, and the heavy 5.2 oz/yd2 polyethylene with a 14 x 14 scrim gives confidence that it will stand up to winter weight and wind when cared for properly. It is best suited to pool owners prioritizing a solid barrier against snow and debris.

Key Features

• Extra Overlap: A 4 ft overlap (cover size 22 x 37 ft) simplifies anchoring and makes draping over rails or decks easier than smaller covers.
• Heavy Material: Constructed from 5.2 oz/yd2 polyethylene so the cover resists stretch and provides a more durable winter barrier than lighter competitors.
• 14 x 14 Scrim: A dense scrim weave increases tear resistance and overall longevity compared with low-scrim covers.
• Solid Construction: The solid design does not allow water to pass through, keeping leaves and dirt out of the pool through the offseason.
• Installation Hardware Included: A winch and cable are provided so owners can secure the cover through the grommets without buying extra tools.
• Long Warranty: Backed by a 20-year warranty, indicating the manufacturer stands behind the material and workmanship.

Who It's For

This cover is aimed at above ground pool owners with an 18 x 33 ft oval pool who want a solid winter barrier and an easier install than low-overlap covers. Homeowners with decks can place the cover over the deck and use vinyl water weights, or route the cable under a partial deck to secure the perimeter.

Those who need a cover that breathes or allows water through should look elsewhere, since this is a solid cover. Also, buyers seeking the absolute thickest industrial fabric might prefer specialty heavy-duty options, as some customers note concerns about long-term durability under extreme conditions.
