MIXC Square Hot Tub Cover 85 x 85 Inch Overcover for 7 ft x 7 ft Spas — 600D Waterproof, Heavy-Duty with Vents

MIXC’s Outdoor Waterproof 600D Square Hot Tub Cover is a heavy-duty, weather-resistant protector sized to fit most 7 ft x 7 ft and similar square spas up to 85" × 85".

Keep your square hot tub cleaner and better protected from rain, snow, UV and debris with a rugged outer shield made from high-density 600D Oxford fabric. This cover is built as an over-layer to work with your existing insulated hard cover beneath—its purpose is to add a waterproof, breathable barrier that extends the life of the underlying cover and reduces maintenance between uses.

How does this cover protect my hot tub from bad weather?

The MIXC cover uses thick 600D waterproof Oxford fabric and reinforced seams to block rain, sleet and light snow while resisting wear from sun and wind. Integrated vents reduce trapped moisture so condensation and mildew are less likely to form under the overlay.

• 600D high-density waterproof outer fabric for reliable rain resistance
• Tear-resistant, high-strength construction for wind and abrasion resistance
• Side air vents to allow moist air to escape and reduce condensation
• Works as an over-cover together with your insulated hard spa lid

Will this fit my spa and how do I secure it?

This model is sized up to 85" × 85" and is intended for square tubs including 84"×84", 83"×83", 82"×82" and standard 7 ft × 7 ft spas. Choose a cover larger than your tub for a proper overhang and measure your spa before ordering. Adjustable straps and an elastic drawcord help keep the cover snug during windy conditions.

• Designed for square tubs up to 85" length and width
• Adjustable buckle straps for fast, secure fastening
• Elastic drawcord for a tailored fit around corners
• Recommended to be used over an existing insulated hard cover

How do I maintain the MIXC waterproof cover?

Maintenance is straightforward: wipe away dirt with mild soap and water, allow the cover to air dry, and store it in a cool, dry place when not needed. Avoid harsh chemicals, sharp objects and prolonged exposure to extreme elements beyond normal outdoor conditions to preserve materials and warranty coverage.

• Clean with mild soap and water; rinse thoroughly
