Essential Tips for Winterizing Your Wood-Fired Hot Tub 🔥❄️

As the temperatures drop and the air gets crisp, few things feel as magical as sinking into a steaming wood-fired hot tub under a winter sky. But before you can enjoy those cozy nights, it’s important to prepare your hot tub properly for the colder months. Winter brings unique challenges—freezing temperatures, extra moisture, and limited sunlight—so a little preparation now will save you time, money, and headaches later.

Whether you're planning to use your tub all winter long or shut it down until spring, this guide walks you through the steps to keep your wood-fired hot tub safe, efficient, and ready for action.

Decide: Will You Use It All Winter or Winterize It?

Before you grab any tools, determine your plan for the season:

✔ Using it during winter?

You’ll need to keep it filled, maintain regular firing, and protect the external stove or chimney.

✔ Closing it down?

You’ll need to drain it fully and protect it from freezing and moisture.

Each path has a slightly different process—so once you know your plan, you’re ready for the next step.

Give Your Hot Tub a Thorough Clean

Whether you're using it or not, winterizing starts with a clean slate.

• Drain the water completely.

• Scrub the interior with a mild, non-abrasive cleaner. Wood-friendly products only!

• Rinse thoroughly to remove any residue.

• Clean the stove, removing ash and soot.

• Check the filter system (if yours has one) and clean or replace filters.

A clean tub ensures fewer issues when temperatures drop and reduces the risk of bacteria growth.

Inspect the Wood and Hardware

Winter weather is hard on wood and metal. Before freezing conditions set in, take a few minutes to inspect:

• Wood panels for cracks or dryness

• Bands/straps for tightness

• Seals and gaskets for leaks

• Stove connections for corrosion or blockages

• Chimney to make sure it’s clear of creosote buildup

If anything needs tightening or repairing, do it before frost makes repairs more difficult.

Protect the Stove and Chimney

Your heater is the heart of your wood-fired hot tub.

If you’ll be using it:

• Store seasoned firewood in a dry location.

• Make sure the chimney cowl is secure to prevent snow and debris from entering.

• Consider adding a heat shield or wind guard if your tub is exposed to the elements.

If you’re shutting it down:

• Empty and clean the firebox.

• Drain all water from the stove jacket, pipes, and coils. Standing water + freezing = cracked metal.

• Cover the stove with a waterproof, breathable cover.

  
  

If You’re Using It All Winter: Keep It From Freezing

A wood-fired hot tub can freeze quickly if left unattended. To keep everything running smoothly:

• Fire it up regularly—at least once every few days depending on climate.

• Keep the water circulating, especially if you have a pump.

• Always keep the main lid on when not in use.

If You’re Not Using It: Fully Winterize

For a full winter shutdown:

✔ Drain every drop

This includes the tub, stove, piping, filters, and heater coils.Even small pockets of water can freeze and cause damage.

✔ Remove accessories

Take out seating, drink holders, and any soft materials.

✔ Dry the interior completely

This prevents mold and swelling/contracting as temperatures fluctuate.

Safety Tips for Winter Hot Tub Use

If you're enjoying your tub in winter, keep these in mind:

• Keep a path cleared and salted to prevent slipping.

• Have a designated area for towels and robes so they stay dry.

• Never fire the stove without enough water in the chamber.

And of course—don’t soak alone in extreme weather.

Enjoy a Cozy, Hassle-Free Winter

With just a bit of preparation, your wood-fired hot tub can bring months of warmth, relaxation, and unforgettable winter nights. Whether you’re soaking under the stars or putting your tub to sleep until spring, these steps ensure it stays in perfect condition and ready for countless seasons ahead.
