Wood Burning Hot Tubs – Natural Fire-Heated Outdoor Soaking

What Is a Wood Burning Hot Tub?

A wood burning hot tub (often also called a wood-fired hot tub) is heated by burning firewood in a dedicated stove connected to the tub. As the fire heats the stove, warm water circulates naturally through the tub, raising the temperature without the need for electrical pumps or heaters.

This type of heating has been used for generations in Scandinavia and Northern Europe and remains popular today for gardens, cabins, holiday homes, and remote locations.

Common Terms Explained

You may see several different names used online. In practice, they all describe the same heating principle:

• Wood burning hot tub – focuses on the fuel source (firewood)
• Wood heated hot tub – highlights the natural heating method
• Fire heated hot tub – emphasizes open-fire warmth
• Wood fired spa – a marketing term for a traditional wood-heated tub

The differences are linguistic rather than technical. All rely on a wood-fired stove to heat the water naturally.

How Does a Wood Burning Hot Tub Work?

A wood burning hot tub heats water using simple and reliable physics:

1. Firewood is lit inside the stove
2. The stove heats water as it passes through or around it
3. Hot water rises into the tub while cooler water flows back to the stove
4. This natural convection continues until the desired temperature is reached

There are two main stove configurations:

External Wood Stove

• Positioned outside the tub
• Frees up interior space for bathers
• Easy to access and clean

Internal Wood Stove

• Installed inside the tub wall
• Faster heat transfer
• Compact and visually minimal

Both systems are efficient, safe when properly installed, and widely used.
