Can Inflatable Spas Be Used in Winter?

When winter rolls around, inflatable spas face a frosty decision—keep bubbling or shut them down? The short answer: yes, you can keep using your spa, but it comes with higher bills and extra effort. The alternative is draining and storing it until spring.

Which option is best? That depends on how often you’ll use it, how much time you’re happy to spend on maintenance, and how much you want to spend on energy. Let’s break it down so you can make the right choice for your family.

How to Safely Use Your Inflatable Spa in Cold Weather

Prepping Your Spa for Winter Use

Check the Manufacturer’s Recommendations

Before you do anything, check your spa’s manual. Some brands encourage year-round use, while others strongly warn against it. Following the manufacturer’s advice will save you from costly mistakes.

Ensure Proper Placement and Ground Protection

Cold ground can quickly sap heat and put stress on your spa’s base. Set it up on a flat, insulated surface—something that cushions and protects against frost. Think of it as giving your hot tub a warm winter coat.

Insulate the Base and Sides

Adding extra insulation makes a big difference. A thermal mat under the spa and wraps around the sides help lock in heat. Without it, you’ll literally be pouring money into the cold ground.

Maintaining Water Temperature and Quality

Use a High-Quality Thermal Cover

A decent cover isn’t just handy—it’s essential. It keeps warmth in, stops debris falling in, and helps keep your electricity bill under control.

Consider a Spa Blanket or Mat

For extra warmth, add a floating spa blanket beneath the cover. It traps heat inside the water and reduces how often the heater needs to kick in.

The Importance of Regular Water Chemistry Checks

Winter doesn’t mean less maintenance. Test your spa water regularly for pH, alkalinity, and sanitiser levels. Poor water balance can damage the spa and make soaking less enjoyable.

Protecting Your Spa from Freezing

Keep the Pump Running

Circulating water is far less likely to freeze. Running the pump ensures constant movement and keeps the heater working effectively.

Use an Anti-Freeze Agent (if recommended by the manufacturer)

Some spa brands allow antifreeze in the system to prevent frozen pipes. Always check your manual before adding anything—better safe than sorry.

What to Do in Extreme Cold

When temperatures plunge and you’re not planning to use the spa, the safest option is to drain, dry, and pack it away. It avoids damage and saves on electricity too.

Essential Tips for Maximising Your Winter Spa Experience

Accessories That Make a Difference

Spa Surround and Steps

Getting into a hot tub on a frosty night feels magical—but also a little slippery. Steps and surrounds make it safer and more comfortable, especially with kids around.

Towel Warmers and Robes

Nothing ruins a soak faster than shivering the second you get out. A warm towel or heated robe waiting nearby is the ultimate winter spa hack.

LED Lighting and Cup Holders

Turn your garden soak into a proper escape. Add LED lights for atmosphere and cup holders for hot chocolate, mulled wine, or whatever keeps you cosy.

Post-Use Care in Winter

Draining and Storing Your Spa

If you’re not planning to use the spa regularly, draining and storing is best. Make sure every drop of water is out and that the tub is fully dry. Even a little moisture can cause mould or freezing damage.

Cleaning and Conditioning the Tub

Once drained, clean the spa thoroughly and condition the vinyl before folding it away. Store it in a cool, dry place out of direct sunlight until spring rolls back around.

Conclusion: Making the Right Decision for Your Inflatable Hot Tub

Whether you keep your spa bubbling all winter or pack it away, the key is preparation. Running it year-round brings cosy evenings under the stars, but also higher bills and more upkeep. Storing it avoids damage and saves money, but means waiting for warmer weather to enjoy it again.

Think about your lifestyle, budget, and how often you’ll actually use it. With the right care—whether in use or storage—your inflatable spa will stay in great shape for many seasons to come.
