iBirdie Outdoor Waterproof Stock Tank Cover for 150 Gallon Oval Tanks — 59x41x12, 600D Reinforced, Drawstring & Velcro

The iBirdie Outdoor Waterproof 150 Gallon Stock Tank Cover is a heavy-duty, weatherproof protective cover sized to fit 150-gallon oval stock tanks (59" x 41" x 12") and built to keep your outdoor cold plunge or stock tank clean and sheltered.

Protecting an outdoor stock tank or ice bath from rain, leaves, sun and debris extends the life of the tank and reduces maintenance. The iBirdie cover uses 600D reinforced fabric, double-stitched seams, taped waterproof seams, and adjustable fastenings to deliver a secure, weather-resistant barrier. It’s designed to fit snugly over 150-gallon oval tanks while offering easy on/off handling and options for added storm security.

How does this cover stand up to wind, rain and sun?

The cover combines a thick 600D weatherproof outer fabric with taped, double-stitched seams to keep water out and resist tearing. An adjustable drawstring and Velcro strap let you cinch the skirt for a tighter hold in blustery conditions. While engineered for strong protection, we recommend supporting the center (for example with boards underneath) during heavy snowfall or prolonged pooling of water.

• 600D reinforced fabric blocks rain and UV exposure
• Double-stitched seams with waterproof tape prevent leaks
• Drawstring and Velcro strap secure fit against wind
• Central support recommended to avoid water pooling

Will this cover fit my 150-gallon oval stock tank?

The cover measures 59 inches long, 41 inches wide and 12 inches high, sized specifically to fit most 150-gallon oval stock tanks. Measure your tank dimensions before ordering to ensure a snug fit, noting that the cover’s height expects a standard rim and shallow overhang. The adjustable cinch helps fine-tune the fit for slightly different tank profiles.

• External dimensions: 59" L × 41" W × 12" H
• Designed for 150-gallon oval tanks and similar shapes
• Adjustable drawstring allows minor size adjustments
• Not intended as a load-bearing snow platform—support center if needed

How easy is the cover to use and maintain?

Installation is straightforward: drape the cover over the tank, pull the drawstring until snug, and secure the Velcro strap for added stability. The durable fabric wipes clean with a sponge and mild soap, and the robust stitching resists fraying so the cover stays functional season after season. When not in use, fold the cover dry and store in a breathable bag or dry space to preserve longevity.

• Quick on/off with drawstring and Velcro fastening
• Wipes clean—no special cleaners required
• Foldable for compact storage between seasons
• Stitched and taped seams reduce maintenance needs

What construction features ensure long-term durability?

iBirdie built this cover with long-term outdoor use in mind: thick 600D fabric resists abrasion and UV fading, while taped seams prevent water ingress at stitch lines. Reinforced hems and double stitching add tear resistance at high-stress points. These elements combine to give a reliable protective barrier that holds up to frequent removal and everyday exposure.

• 600D durable outer fabric for abrasion and UV resistance
• Double-stitched seams with waterproof tape for leak prevention
• Reinforced hems to prevent tearing at attachment points
• Velcro and drawstring hardware rated for outdoor use
