Can You Use an Inflatable Hot Tub in Winter?
Yes - with the right precautions. Using an inflatable hot tub in winter is one of the most enjoyable ways to enjoy the cold season. But winter use requires extra insulation, higher energy budgets, and awareness of freeze risks. Here's everything you need to know.
Winter Use: Temperature Zones Guide
Whether you can comfortably use your inflatable hot tub in winter depends heavily on your local climate. Here's a temperature-based guide:
| Outdoor Temperature | Usability | Recommendation |
|---|---|---|
| Above 50°F (10°C) | Excellent - normal operation | Use freely. Minimal extra cost. |
| 40-50°F (4-10°C) | Good - slightly longer heat times | Use with insulated cover. Moderate cost increase. |
| 32-40°F (0-4°C) | Possible - heater works harder | Use extra insulation. Consider wind barriers. |
| 20-32°F (-7-0°C) | Challenging - high energy costs | Freeze Shield required. Backup plan for power outages. |
| Below 20°F (-7°C) | Not recommended | Winterize and store. Risk of freeze damage too high. |
Tips for Using an Inflatable Hot Tub in Cold Weather
1. Use an Insulated Cover - Always
This is the single most important winter tip. A quality insulated cover prevents up to 60% of heat loss. Models with EnergySense covers (Coleman and SaluSpa) have a significant advantage in winter. Always keep the cover on when not actively soaking.
2. Add a Thermal Floating Blanket
A thermal floating blanket sits on the water surface under the main cover, adding an extra layer of insulation. This can reduce heat loss by an additional 15-20% and cut heating costs. They cost $15-$25 on Amazon and are highly recommended for winter use.
3. Use an Insulated Ground Mat
The ground under your tub is a major source of heat loss. Replace the thin ground cloth with a thick insulated mat, foam board, or even multiple layers of interlocking foam tiles. This prevents cold ground from "stealing" heat from the tub bottom.
4. Set Up Wind Barriers
Wind chill dramatically accelerates heat loss. Position your tub near a wall, fence, or building for natural wind protection. You can also use outdoor privacy screens or create a simple windbreak with lattice panels or outdoor fabric screens.
5. Keep the Water Warmer When Not in Use
In winter, keep your tub at 95-100°F between uses instead of letting it cool down to ambient temperature. Reheating from cold takes 12-24 hours and uses far more energy than maintaining a warmer baseline temperature. The small ongoing cost is much less than the energy spike of reheating from cold.
6. Plan for Power Outages
This is the biggest risk in winter. If power goes out and temperatures are below freezing, water in the pump and lines can freeze and cause permanent damage. Have a plan:
- Monitor weather forecasts for extreme cold or storms
- Know how to quickly drain your tub if extended power outage is expected
- Consider a battery backup or generator for the heater pump
- Models with Freeze Shield only work while plugged in - they don't protect during outages
Winter Energy Costs: What to Expect
Running an inflatable hot tub in winter costs more due to the temperature differential between the water and ambient air. Here's a realistic breakdown:
| Season | Estimated Monthly Cost | With Insulation |
|---|---|---|
| Summer (75°F+) | $20-$35 | $15-$25 |
| Spring/Fall (50-75°F) | $30-$50 | $25-$40 |
| Mild Winter (40-50°F) | $45-$65 | $35-$50 |
| Cold Winter (32-40°F) | $60-$80 | $45-$65 |
| Harsh Winter (below 32°F) | $80-$120+ | $60-$90 |
*Based on average US electricity rates (~$0.16/kWh) and a 4-6 person inflatable hot tub at 104°F.
How to Winterize Your Inflatable Hot Tub for Storage
If you decide to store your inflatable hot tub for winter, follow these steps to prevent mold, mildew, and material damage:
- Add line flush to the water and run jets for 20 minutes to clean internal plumbing.
- Drain completely - use the drain valve and a submersible pump to remove all water.
- Remove and clean the filter. Discard if worn; store if still usable.
- Clean the interior with a vinegar/water solution. Scrub all surfaces.
- Rinse thoroughly and remove all cleaning residue.
- Dry completely - this is critical. Leave open for 24 hours. Use towels to absorb remaining moisture. Any moisture left can cause mold growth during storage.
- Disconnect pump components and ensure they are dry.
- Deflate fully and fold loosely (avoid tight creasing).
- Store in a dry, indoor location - a garage, basement, or closet works. Avoid unheated spaces where temperatures swing dramatically.

Can you use a Coleman SaluSpa in the winter?
Yes, Coleman SaluSpa models can be used in winter, especially in mild climates (above 40°F/4°C). They feature Freeze Shield technology that automatically activates the heater if water approaches freezing temperatures. However, in extremely cold climates (below 32°F/0°C), energy costs increase significantly and the heater may struggle to maintain temperature.
What temperature is too cold for an inflatable hot tub?
Most manufacturers recommend outdoor temperatures above 40°F (4°C) for reliable operation. Below this, the heater works harder, energy costs spike, and there is increased risk of component damage. Below 32°F (0°C), there is serious risk of freezing if the heater fails or loses power. If you live in a region with temperatures regularly below 20°F (-7°C), winterizing and storing is recommended.
Will an inflatable hot tub freeze in winter?
An inflatable hot tub can freeze if the heater fails or loses power while left set up in freezing temperatures. Frozen water can crack the pump, damage internal plumbing, and split seams. Models with Freeze Shield (Coleman/SaluSpa) have automatic protection, but this only works while plugged in with power. A power outage in freezing weather is the biggest risk.
How much does it cost to run an inflatable hot tub in winter?
Winter operation costs $50-$80+ per month in electricity, compared to $30-$60 in warmer months. The heater runs much more frequently to maintain temperature against cold air. Using an insulated cover, thermal floating blanket, insulated ground mat, and wind barriers can reduce costs by 30-40%. In very cold climates, costs can exceed $100/month.
Should I store my inflatable hot tub for winter?
In mild climates (winter temps above 40°F/4°C), you can use it all winter with proper precautions. In cold climates (regular temps below 32°F/0°C), storing is recommended to protect the tub and save on energy costs. If storing: drain completely, clean thoroughly, dry fully (critical to prevent mold), deflate, and store indoors in a dry location.
How do I winterize my inflatable hot tub for storage?
To winterize for storage: 1) Add line flush and run jets for 20 minutes. 2) Drain all water completely. 3) Remove and clean the filter. 4) Clean interior with vinegar solution. 5) Rinse thoroughly and let dry completely (use towels and leave open for 24 hours). 6) Disconnect and dry pump components. 7) Deflate the tub fully. 8) Fold loosely and store in the original box or a dry bag. 9) Store indoors in a dry, temperature-stable location.
