Best Hot Tubs for Cold Climates: Keep Warm All Winter in Minnesota




person-in-hot-tub-in-winter

A hot tub can be the perfect escape from Minnesota’s cold winters, but can your spa endure the season’s harsh wind, rain, and snow? Not all hot tubs are designed to withstand cold climates, so choosing a hot tub that combines durability with energy efficiency is key.

Here, we break down what makes a hot tub winter-ready and how you can keep yours in great shape through the colder months.

1. Energy Efficiency: Save Money While Staying Warm

In a cold climate, your hot tub has to work harder to maintain warmth, requiring more energy—and more money—if your spa isn’t energy-efficient. To maximize efficiency, check your hot tub’s insulation type and plumbing design.

2. Full-Foam Insulation: The Best Option for Cold Climates

The insulation system of your hot tub can make all the difference in winter performance. Many hot tubs use perimeter insulation to reduce manufacturing costs, but full-foam insulation is far superior. Full foam surrounds the interior cabinet with insulating material, shielding your hot tub from the cold while providing structural support.

A study by Hot Tub University concluded that full-foam spas outperform perimeter-insulated models by more than double in heat retention. With full foam, your spa’s components are better protected against the cold, and the reduced motor and jet vibrations extend the lifespan of these components, reducing the risk of breakdowns.

3. Durable Covers: Essential for Minnesota Snow and Wind

A well-fitted cover is crucial for protecting your spa from the winter elements. The best covers are those specifically designed for your hot tub model, ensuring a snug fit that seals in warmth and keeps out cold air. Look for a cover that’s durable enough to support the weight of snow after a storm and won’t open in strong winds.

4. Protecting Your Spa from the Elements: Sun, Snow, and Wind

While full-foam insulation and a durable cover protect your spa, extra steps can keep it performing optimally through each season. Consider adding a Covana Gazebo for further shelter from snow, wind, and UV rays, all of which can wear on your spa over time. Proper placement, such as installing your hot tub under an eave or within a gazebo, also provides added weather protection.

5. Winter Spa Care: Keep It Running All Season Long

Did you know that the highest-quality spas, like Cal Spas, typically don’t require winterizing? With their energy-efficient designs and high-quality materials, these spas are made to withstand freezing temperatures, keeping your pipes from freezing even in the harshest Minnesota winter. If you won’t use your hot tub for more than six weeks, however, winterizing may be necessary to protect your investment.
