Why People Love Hot Tubbing in Vermont Winters

Cold weather soaking isn’t just a vibe — it’s full of real benefits.

1. Muscle Relief & Recovery

The hot water helps relax tight muscles that get stiff from cold temps, shoveling snow, or winter workouts.

2. Stress Relief

Something about snowy views + steamy water = total mood reset.

3. Better Sleep

Hot water raises your body temperature, then cools it rapidly afterward, helping you fall asleep easier.

4. Circulation Boost

The cold-to-warm transition improves blood flow, perfect for chilly Vermont days.

5. It’s basically a winter oasis

When everything around you is frozen, your hot tub becomes your personal outdoor spa retreat.

Do Hot Tubs Work in Freezing Weather?

Short answer: Yes — if they’re properly maintained.

Hot tubs are designed to operate year-round, even in temperatures that drop into the negatives. But you MUST keep:

• The heater working

• Water levels full

• The water circulating

• The covers insulated and sealed

Vermont winters are tough, but a well-maintained hot tub can handle them.

How to Use a Hot Tub Safely in Freezing Weather

Here’s where the Vermont-specific advice comes in.

Keep Your Hot Tub Running 24/7

In freezing temperatures, the hot tub should never be turned off.
Running water = warm water = no freezing pipes.

Check Water Levels Regularly

Evaporation happens fast in cold, dry air.
If the water level gets too low, the heater and pumps can shut off — and that’s when freezing becomes a risk.

Use a High-Quality, Insulated Cover

Heavy snow, wind, and cold air can zap heat quickly.
A good cover helps:

• Keep heat in

• Keep debris out

• Reduce energy costs

• Prevent evaporation

• Protect the shell

Avalon Pools & Spas carries winter-ready insulated covers perfect for Vermont’s climate.

Maintain Proper Water Chemistry

Even in winter, balance your water!
Keep an eye on:

• pH

• Alkalinity

• Sanitizer levels

• Calcium hardness

Unbalanced water can damage equipment — especially in freezing weather.

Check Filters Weekly

Dirty filters force your hot tub to work harder, which can strain pumps and heaters.

Snow Removal Matters

Clear snow off the hot tub cover to prevent:

• Heat loss

• Cover damage

• Extra weight on the shell

Use a soft broom or brush — never a shovel.

How Cold Is Too Cold for a Hot Tub?

Great news: there’s no official “too cold” temperature, as long as the hot tub is running and cared for properly.

The air can be:

• 20°F

• 10°F

• 0°F

• Even –10°F or colder

Your tub can still run safely.
Hot tubs are designed to combat cold temps — especially the premium brands Avalon Pools & Spas sells.

The water temperature is what matters. Most Vermonters keep their winter soaking temp between 100°F–104°F.

Energy Efficiency Tips for Winter Hot Tub Use

Using your hot tub during a Vermont winter will use more energy — but these tips keep costs manageable:

• Use an insulated cover
• Add a thermal blanket under the cover
• Avoid long soak sessions with the cover off
• Keep jets on low settings
• Maintain clean filters
• Keep water balanced
• Don’t drain and refill mid-winter

Avalon Pools & Spas can also recommend energy-efficient hot tubs for Vermont homeowners who want high performance with lower winter operating costs.

Should You Drain Your Hot Tub in Winter?

No.
Do not drain your hot tub when it’s freezing outside.

The plumbing can freeze before you refill it.
Frozen pipes = expensive repairs.

If you absolutely have to drain your hot tub (for repair or deep cleaning), let Avalon Pools & Spas handle the winterization safely.

Winter Hot Tub Prep Checklist (VT Edition)

Before the temperature drops, make sure you:

• Inspect and clean filters

• Test all jets and pumps

• Check heater function

• Balance water chemistry

• Top off water

• Replace worn-out covers

• Ensure the cover skirt seals tightly

• Check for air leaks around the cabinet

• Confirm freeze protection settings are working

FAQ: Using a Hot Tub in Freezing Weather

Can a hot tub freeze in the winter?

Yes — but only if it’s turned off or water isn’t circulating. A properly running hot tub will not freeze.

Is it safe to go from freezing air into a hot tub?

Absolutely. Just keep your head warm, limit time outdoors when wet, and avoid alcohol.

Can I use my hot tub during a snowstorm?

Yep! Just be cautious walking on slippery surfaces and keep the cover protected from excess snow weight.

How often should I check water chemistry in the winter?

Once a week is ideal — more if you use the hot tub daily.

Should I lower the temperature to save money?

You can drop a few degrees, but don’t let the water fall below 95°F in mid-winter.
