Winter Hot Tub Care: Keep Your Water Clean & Clear All Season Long
There’s nothing quite like slipping into a warm, bubbling hot tub on a crisp winter evening. But to truly enjoy your soak, you’ll want to make sure your water stays clean, clear, and inviting—even in the coldest months. Winter hot tub maintenance takes a little extra attention, but with the right routine, you can keep your spa fresh all season long.
Here’s your ultimate guide to keeping your hot tub water clean in winter!
1. Keep the Cover Clean & Secure
Your hot tub cover is your first line of defense against winter debris like leaves, snow, and dirt. A well-maintained cover helps prevent contaminants from entering the water. Here’s how to keep it in top shape:
✅ Brush off snow & ice to prevent excess weight and damage.
✅ Wipe down the underside of the cover regularly to prevent mold and mildew.
✅ Ensure a snug fit to keep out dirt and minimize heat loss.
A clean, well-fitted cover not only keeps your water pristine but also helps save energy!
2. Maintain Proper Water Chemistry
Cold weather doesn’t mean you can skip water testing! Balancing your water chemistry is key to preventing bacteria growth, cloudy water, and scale buildup. Aim for these ideal levels:
✔ pH: 7.4 – 7.6
✔ Alkalinity: 80 – 120 ppm
✔ Sanitizer (Chlorine or Bromine): 3 – 5 ppm
Test your water at least once a week, and adjust chemicals as needed to keep it balanced.
3. Shock the Water Regularly
Winter hot tubbing means less evaporation and more contaminants (body oils, lotions, and sweat). Shocking your spa once a week with a non-chlorine or chlorine shock will help:
🔹 Break down organic waste
🔹 Prevent cloudy or smelly water
🔹 Boost sanitizer efficiency
Always shock your hot tub after heavy use or when the water starts looking dull.
4. Rinse Your Filters More Often
Your filters work overtime in the winter, catching debris and keeping your water crystal clear. Make sure to:
🌀 Rinse filters weekly with a garden hose to remove buildup
🌀 Soak in a filter cleaner every month for a deep clean
🌀 Replace filters annually (or as needed) for peak performance
A clean filter = cleaner water and a happier hot tub!
5. Keep the Water Moving
Stagnant water can lead to bacteria growth and freezing issues. If you’re using your hot tub less frequently in winter:
🌡 Set your circulation pump to run daily
🌡 Run the jets for 10-15 minutes every few days if your tub isn’t in use
🌡 Check for proper water flow to prevent freezing in extreme cold
Keeping the water moving ensures consistent heat distribution and prevents unwanted surprises!
6. Drain & Refill Before It Gets Too Cold
If your water is more than 3-4 months old, it’s best to drain and refill before deep winter sets in. Changing water in freezing temperatures can be tricky, so plan ahead and refresh your spa when the weather is mild.
Tip: If you must drain in winter, use a submersible pump to speed up the process and refill quickly to avoid freezing pipes.
7. Be Prepared for Extreme Cold
If a deep freeze is on the way, take these precautions:
❄ Keep the cover securely in place
❄ Ensure water is properly heated and circulating
❄ Check for power outages—a frozen hot tub can cause serious damage!
For peace of mind, consider using a remote temperature monitor to keep an eye on your spa’s status from the comfort of your home.
