iBirdie Hot Tub Spa Cover 85 x 85 in (7x7 ft) Waterproof Outdoor with 18-in Skirt & Air Vents

iBirdie 85 x 85 inch outdoor hot tub SPA cover is a heavy-duty, waterproof fabric protector designed to shield 7 x 7 ft hot tubs from rain, snow, debris and sun while fitting over a rigid hard top.

This cover adds a lightweight, breathable barrier on top of your existing hard spa lid to keep moisture, leaves and UV exposure from contacting the hard cover directly. Sized at 85 inches by 85 inches with an 18-inch skirt height, it’s built for 7 x 7 foot spas and features reinforced seams, air vents, handles and corner fastenings to hold it securely during changing weather.

How will this cover protect my hot tub through seasons?

The iBirdie cover is made from heavy-duty fabric treated with a waterproof coating to resist rain and snow. Double-stitched seams with seam sealant help prevent leaks and tearing so the hard top beneath stays cleaner and drier year-round.

• Waterproof coated fabric blocks precipitation and splashes.
• Double-stitched seams with sealant reduce seam failures.
• Air vents let trapped moisture escape to limit condensation.
• UV-resistant material helps reduce sun damage to the hard cover.

Will this fit my spa and stay in place during wind?

This cover measures 85" long, 85" wide and 18" high—measure your hot tub’s length and width first and order a cover larger than the tub for proper coverage. Four adjustable buckles and waterproof corner zippers secure the cover to the hard top and help keep it stable in breezy conditions.

• Size: 85 in × 85 in footprint with an 18 in skirt for side coverage.
• Adjustable buckles at four points to tighten the fit.
• Waterproof zippers at corners give extra wind resistance.
• Two fabric handles make aligning and removing the cover easy.

Does this cover breathe or trap moisture under the lid?

Breathability is built into the design via air vents on both sides to help expel trapped humidity, lowering the chance of mildew forming underneath. While vents reduce internal moisture buildup, this product is intended as an outer weather barrier and not as insulation—continue using your hard insulated lid beneath for thermal protection.

• Dual side air vents allow airflow and moisture escape.
• Helps limit condensation on the hard cover underneath.
• Not a replacement for an insulated hard cover—use both together.

How durable is the material and how is it constructed?

iBirdie builds the cover from heavy-duty fabric with a waterproof coating and reinforces stress points with double stitching plus seam sealant to resist tears, leaks and wear. The construction is focused on outdoor longevity and everyday handling—easy to put on and remove thanks to sewn handles.

• Heavy-duty outer fabric with waterproof finish for weather resistance.
• Double-stitched seams and sealant increase tear and leak resistance.
• Integrated handles for easy placement and removal.
• Designed to cover and protect an existing hard top, not to replace it.

Who is this for? The iBirdie 85 x 85 inch outdoor hot tub SPA cover is suited for hot tub owners with 7 x 7 ft spas who want a durable, easy-to-use outer barrier to protect their hard cover from debris, precipitation and UV exposure. It’s ideal for yards exposed to wind, trees or frequent seasonal weather changes, and for anyone who wants a breathable, secure cover that pairs with their existing insulated hard top.
