Naturally fired. Properly heated. Deeply relaxing.

We all love sinking into the dry heat of a wood-fired sauna or soaking in the quiet calm water of a traditional hot tub – especially when it is naturally heated with long lasting kiln dried firewood rather than electricity. The experience is that much more authentic and a genuine experience at home, or in a spa.

At Randalls, we supply kiln-dried hardwood that gets your sauna or hot tub up to temperature fast – and keeps it constant throughout your wellbeing session.

Whether you’re heating a small garden sauna or hot tub for your own relaxation ritual, or running a commercial spa that relies on consistent heat and reliability, we deliver firewood that performs.

Our kiln-dried hardwood logs light quickly, burn cleanly, and deliver the long, intense heat that wood-fired saunas and hot tubs need to stay hot for hours.

Wood Fired Sauna

Using wood-fired saunas and hot tubs isn’t just a luxury – it’s good for body and mind. From improved circulation to stress relief, muscle recovery to better sleep, the benefits of regular sauna use are well documented. And wood-fired systems offer a more natural, grounding experience.

Wood Fired Hot Tub

Wood-fired hot tubs offer several benefits, including being eco-friendly, promoting relaxation, and requiring less maintenance than electric or gas-powered tubs. They provide a unique, rustic experience with the ambiance of a crackling fire and the scent of burning wood.

There’s something elemental about lighting the fire yourself, hearing it crackle, and feeling the warmth build from within.
