What Is a Wood Fired Hot Tub?

A wood fired hot tub is an outdoor hot tub heated using a wood-burning stove rather than electricity. The stove heats the water directly, circulating warmth through the tub until it reaches a comfortable bathing temperature, typically between 37–40°C.

The tub itself is usually made from durable timber such as thermowood, spruce, or larch, often combined with a smooth internal liner for hygiene and easy maintenance. The stove can be positioned inside the tub (integrated) or outside the tub (external), depending on the design and preference.

Wood fired hot tubs are valued for their:

• Simple construction
• High reliability
• Independence from the power grid
• Authentic bathing experience

They represent the original form of outdoor hot tubbing, long before electric pumps and digital controls became common. Some buyers also compare niche brands such as Salty Barrel hot tubs with manufacturer-built alternatives like TimberIN.

Why Choose a Wood Burning Hot Tub?

Choosing a wood burning hot tub is not just about heating water — it is about lifestyle, atmosphere, and freedom.

No Electricity Required

One of the biggest advantages is that a wood fired hot tub works without electricity. This makes it ideal for:

• Off-grid homes
• Remote cabins and lodges
• Rural gardens
• Holiday rentals and glamping sites

There are no cables, no power upgrades, and no ongoing electrical consumption.

Authentic Outdoor Experience

The crackling sound of fire, the smell of burning wood, and the gentle warmth of water create a bathing experience that electric systems simply cannot replicate. Many owners describe it as more relaxing, more social, and more connected to nature.

Lower Long-Term Running Costs

While wood is required, it is often cheaper and more predictable in cost than electricity. Many users source their own logs or use local firewood, keeping running costs low over time.

Powerful Natural Heat

A properly designed wood stove can heat water efficiently even in cold weather, making wood fired hot tubs suitable for year-round use, including winter bathing. Some buyers researching wood-fired hot tubs also compare Nordic brands such as Kirami with European manufacturers like TimberIN®.

Off-Grid Hot Tubs – Freedom to Install Anywhere

An off grid hot tub is one of the strongest reasons people choose wood fired heating.

Because no permanent electrical connection is required, wood fired hot tubs can be installed in places where electric hot tubs are impractical or impossible:

• Forest cabins
• Mountain lodges
• Countryside properties
• Temporary or seasonal locations

For glamping businesses and holiday accommodation owners, this flexibility is a major advantage. Guests love the idea of soaking in hot water heated by real fire, especially in scenic or remote surroundings.

Off-grid capability also means fewer regulatory hurdles, no worries about outdoor electrical safety, and a simpler installation overall.

How Does a Wood Fired Hot Tub Work?

The heating process is simple yet highly effective:

1. The tub is filled with water
2. The wood stove is loaded with dry firewood
3. The fire heats the metal stove body
4. Heat transfers directly to the surrounding water
5. Warm water circulates naturally inside the tub

There are no pumps required for heating. Circulation happens through natural convection, making the system reliable and easy to maintain.

Depending on tub size, stove power, and outdoor temperature, the water typically heats in 2–4 hours.

Wood Fired Hot Tub Heating Options

Understanding heating configurations is essential when choosing the right model.

External Wood Fired Stove

An external stove sits outside the tub and connects via water inlets.

Advantages:

• More internal bathing space
• Easier to add wood while bathing
• Higher stove power options available

This is the most popular choice for family-sized and larger hot tubs.

Integrated Wood Stove

An integrated stove is located inside the tub, usually behind a protective guard.

Advantages:

• Compact, traditional appearance
• Slightly faster initial heat transfer
• Ideal for smaller tubs

This option appeals to those seeking a classic, minimalist design.

Both systems deliver excellent performance — the choice depends on space, aesthetics, and personal preference.

How Long Does a Wood Fired Hot Tub Take to Heat?

Heating time depends on several factors:

• Water volume – larger tubs take longer
• Stove power – stronger stoves heat faster
• Wood quality – dry hardwood burns hotter
• Outdoor temperature – cold weather increases heat-up time

As a general guide:

• Small tubs: 1.5–2.5 hours
• Medium tubs: 2–3 hours
• Large family tubs: 3–4 hours

Once heated, maintaining temperature requires only occasional refuelling.

Is a Wood Fired Hot Tub Eco-Friendly?

A well-used wood fired hot tub can be a surprisingly eco-conscious choice.

Renewable Fuel Source

Wood is a renewable energy source when responsibly sourced. Unlike fossil fuels, it forms part of the natural carbon cycle.

No Standby Energy Use

Electric hot tubs consume power continuously to maintain temperature. Wood fired tubs use energy only when you choose to heat them.

Long Lifespan

High-quality wooden hot tubs are built to last many years, reducing waste compared to short-lived inflatable alternatives.

For environmentally conscious buyers, this balance of natural materials and efficient heating is a strong advantage.

Maintenance and Care of Wood Fired Hot Tubs

Wood fired hot tubs are known for their simplicity, but basic care is essential.

Stove Maintenance

• Remove ash regularly
• Check chimney airflow
• Use dry, untreated wood

Water Care

• Change water periodically
• Use appropriate water treatment
• Clean internal surfaces as needed

Winter Use

Wood fired hot tubs perform exceptionally well in winter. In freezing conditions, ensure water is not left standing unused for long periods, or drain the tub after use if required.

Overall maintenance is straightforward and does not require specialist servicing.

Wood Fired vs Electric Hot Tubs

Understanding the differences helps buyers make the right choice.

Wood Fired Hot Tubs

• No electricity required
• Traditional bathing experience
• Lower running costs
• Manual heating process

Electric Hot Tubs

• Instant temperature control
• Continuous filtration systems
• Higher energy consumption
• More complex components

Neither option is “better” — they serve different lifestyles. Wood fired hot tubs appeal to those who value authenticity, independence, and outdoor living.

Design, Size, and Configuration Options

While this page focuses on heating, wood fired hot tubs are available in many configurations:

• Compact tubs for 2–4 people
• Family-sized tubs for social bathing
• Round or square designs
• Above-ground or partially sunken installations

Additional features such as air or hydro massage systems, steps, insulation, and covers can be selected depending on the model.

Choosing the right configuration ensures comfort, safety, and long-term enjoyment.

Safety Considerations

Wood fired hot tubs are safe when used correctly.

Key points include:

• Never overheat the water
• Keep children supervised
• Maintain clear space around the stove
• Follow installation and ventilation guidelines

Quality construction and proper use ensure years of safe relaxation.

Who Are Wood Fired Hot Tubs Best For?

A wood burning hot tub is ideal for:

• Homeowners seeking natural outdoor wellness
• Rural and off-grid properties
• Sauna and spa enthusiasts
• Holiday rental owners
• Anyone who enjoys hands-on, traditional heating

They are less suited to those who want instant, automated spa operation — but perfect for those who appreciate ritual and atmosphere.

Choosing the Right Wood Fired Hot Tub

When selecting your model, consider:

• Number of users
• Available space
• Preferred stove type
• Frequency of use
• Installation environment

Once these factors are clear, choosing the right design becomes straightforward.

Frequently Asked Questions (UK)

How long does a wood fired hot tub take to heat in the UK?

Most wood fired hot tubs reach bathing temperature in around 2–4 hours, depending on tub size, stove power, outside temperature, wind, and the type of firewood used. In colder UK weather, good insulation and a well-fitted cover can reduce heat loss during warm-up.

Do wood burning hot tubs work well in cold UK weather?

Yes. A wood burning hot tub is ideal for cooler climates because the stove produces strong heat and you can top up the fire as needed. Many owners enjoy year-round use, including autumn and winter, as long as you follow basic water and frost care guidance.
