The outdoor wellness market in the UK has expanded steadily for several years. Garden offices, outdoor saunas, cold plunge pools, and fire pits have all seen surging demand as homeowners invest in their outdoor spaces as genuine extensions of their living environment. Among all of these, wood-fired hot tubs sit in a particularly interesting position: widely admired, frequently considered, and more accessible than most people assume.
If you have been thinking about one and talking yourself out of it, the case for acting is stronger than the case against.
What Makes Wood-Fired Different
The core difference between a wood-fired hot tub and an electric model is in how it heats. An electric tub draws from a power supply, runs through a heating element, and reaches temperature at the touch of a button. A wood-fired tub heats through a firebox, either sitting inside the tub or alongside it depending on the design, using natural convection as the fire burns. The process takes two to three hours. It also costs a fraction of an electric session to run, requires no permanent electrical installation, and integrates nothing into your energy bill.
That practical difference generates a secondary benefit that is harder to quantify but easy to feel. The ritual of preparing a wood-fired tub, loading the firebox, lighting the fire, monitoring the temperature, and waiting for the water to come up to heat is part of what makes it restorative. By the time you step in, you have already spent time disconnecting from screens and engaging with something physical. The experience begins before the soaking does.
The Wellness Case
Regular hot water immersion has documented physiological effects. Warm water dilates blood vessels, lowers blood pressure, reduces muscle tension, and supports circulation. The parasympathetic nervous system response triggered by sustained heat reduces cortisol and activates a state associated with recovery and rest. Used in the evening, it consistently improves sleep onset and depth.
For people managing high-stress working lives, chronic tension, or physically demanding occupations, the decompression of a weekly hot tub session accumulates into tangible improvements in how the body feels. For those who exercise regularly, the heat helps clear lactic acid from muscles and reduce next-day soreness.
Royal Tubs manufactures wood-fired hot tubs in the UK from sustainably sourced timber, with a range spanning the classic Wooden model, the Deluxe with premium pipework and modern convenience features, the compact Ofuro designed for smaller spaces, and the spacious Square model. Each comes with a high-grade steel stove and is available with extensive customization options including interior colour, exterior timber finish, jets, lights, and filtration. Prices start at around £1,245 with nationwide delivery and finance available.
Because Royal Tubs builds in the UK, lead times are shorter than importing from Scandinavian suppliers, which have historically dominated the wood-fired hot tub market. The company also manufactures outdoor saunas and ice tubs, allowing buyers to assemble a full outdoor contrast therapy circuit from a single source.
Practical Considerations Before You Buy
Space is the first thing to plan around. Most round models sit between 1.5m and 2m in diameter, with clearance needed around the perimeter for safe access and firebox operation. A flat, stable surface, whether existing ground, paving, or a purpose-built deck, is required.
Water management in a model without built-in filtration comes down to two approaches: chemical treatment with a cover between sessions, or emptying and refilling after each use. For occasional users, the latter is often simpler and more practical. Neither approach is especially burdensome, but it is worth deciding your preference before purchase.
Firewood supply is the recurring operational consideration. A session typically uses one to two bags of kiln-dried hardwood, costing roughly £6 to £15. Having a reliable local supplier and storage space for wood makes the ownership experience consistently smooth.

FAQ
How long does it take to heat a wood-fired hot tub from cold? Most wood-fired hot tubs reach a comfortable bathing temperature of around 38°C in two to three hours, depending on the starting water temperature and outdoor conditions. Many owners light the fire in the early afternoon for an evening soak.
Do you need planning permission to install a wood-fired hot tub in the UK? In most residential gardens in England and Wales, no planning permission is required. A wood-fired hot tub is treated as a temporary outdoor structure. If you live in a listed building, conservation area, or area of outstanding natural beauty, it is advisable to check with your local planning authority before purchasing.
Are wood-fired hot tubs suitable for year-round use? Yes. Winter use is genuinely one of the most enjoyable aspects of owning a wood-fired hot tub. The contrast between cold outdoor air and warm water is particularly satisfying during the colder months, and many owners find that their tub gets more use in autumn and winter than in summer.
How much does it cost to run a wood-fired hot tub per session? Running costs are primarily the cost of firewood. A typical heating session uses one to two large bags of kiln-dried hardwood, costing between £6 and £15 depending on your supplier. There are no electricity costs associated with heating, making wood-fired tubs significantly cheaper to run per session than electric alternatives.
Can a wood-fired hot tub be used for a commercial property such as a glamping site? Yes. Wood-fired hot tubs are a well-established feature in the glamping and rural accommodation market. They offer a standout amenity that supports premium nightly rates, require relatively little operator maintenance, and are durable enough for regular use across seasons. Royal Tubs caters specifically to this market and provides guidance for commercial buyers.
