Tip: double-check your tank’s size before ordering so the fit is actually the “perfect size” part.

What this cover is for

This Rubermaid 100-gallon waterproof stock tank cover is intended for outdoor setups like a cold plunge/ice bath style tank or other livestock water trough use.
The biggest appeal is the zipper access: you can unzip a section to reach the water without removing the whole cover every single time.

It’s made with heavy-duty waterproof Oxford fabric and includes features meant to help it stay secured in outdoor conditions, including bungee cord securing and reflective strips for better visibility.

Quick fit check

The cover is described as suitable for a stock tank pool around:
54 inches long, 35 inches wide, and 6 inches down.
If your tank differs, it may not sit as intended—so it’s worth measuring first.

Key Features

Upgraded zipper access
Unzip just a section at the seam so you can reach the water without pulling off the whole cover.
Waterproof + insulated design
Built to help protect against outdoor mess and support temperature protection for covered use.
Bungee cord securing
Helps keep the cover in place and reduces the “blown away” problem in windy weather.
Reflective strips
Reflective elements on the front and back are intended to make it easier to notice at night.
Hook rope for weighting
The bottom includes a hook rope intended for hanging sandbags to add stability in strong winds.
Heavy-duty fabric + stitching
Described as waterproof Oxford fabric with precision double stitching and an anti-UV coating.

Why This Product Exists

This cover is basically for people who want their outdoor stock tank setup to look (and stay) more “ready” on a day-to-day basis.
At some point, most of us realize leaving a tank uncovered turns into extra cleaning, extra debris, and extra annoyance.

The zipper access is also a practical touch—because nobody wants to remove a big cover every time they need to check or use the water.

Best Fit For

  • Outdoor 100-gallon stock tank setups that need a waterproof, insulated cover
  • People who want easier access thanks to a zipper section (instead of fully removing the cover)
  • Situations where visibility at night matters, thanks to reflective strips
  • Owners who want added protection from wind, rain, dust, and general outdoor debris

It’s also described as having universal compatibility for other outdoor setups like kids water tables or some outdoor furniture use cases—though the fit is the main thing to verify for your tank.

Final Verdict

If you’re using a 100-gallon stock tank outdoors and you’re tired of the “uncovered tank chaos,” this waterproof insulated cover is a solid, practical option.
The zipper access is the standout feature for everyday use, and the securing/reflective details are there for real-world outdoor conditions.
Just make sure the sizing matches your specific tank before you commit.
