Hot Tub Winter Care Guide

Winter is one of the best times to enjoy your spa. The contrast of hot water and cold air is amazing, and AquaSolus hot tubs are built for the chilly winter months.

Here’s how we recommend looking after your hot tub in winter

Whether you’re soaking in December or shutting it down for a few weeks, these tips will help protect your spa from damage, high bills, and frozen pipes.

Keep it running and don’t switch it off

Unless you’re fully draining your tub, always keep the water circulating. Turning it off in cold weather risks freezing the water inside your pipes and pumps, which can cause cracks or major damage.

Good to know:

• Set the water temperature to around 37–38°C
• Use “economy mode” if you’re away but still want protection
• Run a circulation cycle daily to prevent freezing

Clean your filters and check your water balance

Clean filters work better in cold months, and proper water chemistry prevents limescale and bacteria. The AquaSolus chemical range has what you need to keep it balanced.

We recommend checking your water at least once a week. If you need a quick refresh, read our guide on how to clean your hot tub filter.

Insulate your hot tub and your cover

Most AquaSolus hot tubs already include advanced insulation, but adding a floating thermal blanket or upgrading your cover can make a real difference in winter.

Bonus tip: Use windbreaks, like a fence or hedge, to cut down heat loss even more.

What if you’re not using your hot tub in winter?

If you plan to close it down, be sure to do it right. Just turning it off can be risky if any water remains inside the pipes.

• Fully drain all water from the shell and plumbing
• Use a wet vac to remove hidden water from jets
• Leave the drain valve open
• Cover securely and check it every few weeks

Draining it anyway? It’s a good moment for fresh water: see how often should you change hot tub water.
