Why is my hot tub cover so heavy, and what should I replace it with?

Short answer: Most hot tub covers get heavy because the foam inside slowly soaks up water. Once the foam is waterlogged, the cover gets hard to lift, stops insulating well, and usually can't be fixed. It's time for a new cover. Arctic Spas owners have two good options: the Arctic Spas Polar Cover or the Smartop hard cover.

Why covers get heavy

A standard spa cover is foam wrapped in plastic and vinyl. Over the years, steam and moisture from the hot tub work their way into the foam. Waterlogged foam is heavy and loses its insulation value, so your spa uses more energy to stay hot.

Signs it's time to replace your cover

  • The cover is much heavier than it used to be, or hard to lift
  • It smells like mildew
  • The vinyl is cracking, torn, or falling apart
  • It sags in the middle or doesn't seal well
  • It just looks bad in your backyard

Your replacement options

Arctic Spas Polar Cover

The factory replacement cover built to fit your Arctic Spa. A good choice if you want a traditional cover made for your model.

Smartop hard cover

A hard cover made of aluminum and hard plastic. As shown in the video:

  • Easy to use: open and close it with one hand.
  • Doesn't absorb water: it doesn't rely on foam for structure, so moisture stays out of the insulation and it keeps insulating well over its life.
  • Lasts longer: hard materials hold up in the sun better than soft vinyl or canvas.
  • Replaceable parts: fix it instead of throwing it away.
  • Looks better: a modern look that stays nicer longer.
