The Ultimate Guide to Wood-Fired Hot Tubs: Everything You Need to Know

Wood-fired hot tubs offer a beautifully simple way to relax outdoors — no electricity, no noisy pumps, just heat, water, and nature. With modern materials and smart design, they’re now more efficient and durable than ever. Whether you’re new to the idea or ready to invest, this guide walks you through everything you need to know about wood-fired hot tubs.

What Is a Wood-Fired Hot Tub?

A wood-fired hot tub is an outdoor soaking tub that uses a wood-burning stove to heat the water — no power supply needed. Instead of traditional all-wood construction, modern tubs often feature a durable fibreglass or acrylic liner, providing comfort, better heat retention, and easier maintenance. The exterior, or cladding, can be natural timber for a classic look, or composite cladding for a low-maintenance, weather-resistant finish.

How Do They Work?

You simply fill the tub with cold water, light a fire in the integrated or external stove, and let the heat circulate through a system of water jackets or pipes. Thanks to improved insulation and efficient stoves, our hot tubs typically heat up in just 1.5 to 3 hours, depending on the size and conditions.

Choosing the Right Model

Here’s what to think about when selecting a wood-fired hot tub:

Size: From cozy 2-person tubs to family-sized 5–8 person options.

Liner Material:

·        Fibreglass: Strong, lightweight, and excellent at holding heat.

·        Acrylic: Smooth, highly resistant to wear, and easy to clean.

Cladding Options:

·        Timber: Warm, rustic aesthetics with a natural finish.

·        Composite: Weatherproof, long-lasting, and maintenance-free.

Stove Type:

·        Internal Stoves: Heat faster but slightly reduce internal space.

·        External Stoves: Leave more room inside the tub and are easy to access.

Heating Tips for Best Performance

Burn dry hardwood like oak or ash for a steady, hot flame.

Stir water occasionally to circulate heat evenly.

Use a thermometer to monitor temperature (ideal range: 37–39°C or 98–102°F).

Keep the lid on during heating to trap warmth and reduce heating time.

Maintenance Is Simple

Unlike electric spas, wood-fired tubs have fewer moving parts and are easy to care for:

Liners: Just rinse or wipe down regularly; no need for harsh chemicals.

Water: Change periodically depending on frequency of use.

Stove: Empty ash after a few uses and keep firebox clean.

Cladding:

·        Timber can be oiled to maintain its look.

·        Composite requires just a quick rinse to stay clean.

A modern wood-fired hot tub offers the perfect mix of traditional charm and modern convenience. With quick heating times, durable fibreglass or acrylic interiors, and the option for timber or composite cladding, it's never been easier to enjoy luxurious outdoor soaking — naturally and sustainably.
