The difference is real but smaller than enthusiasts claim. What changes, what doesn't, and which Bristol venues run which.
Ask around Bristol's sauna scene and you'll be told fairly quickly that wood-fired is the real thing and electric is a compromise. That's overstated, but there is a genuine difference and it's worth understanding before you pick.
What actually differs
Heat quality. A wood stove holds a large mass of stones at a high temperature, so when you pour water on it you get a dense, fast burst of steam that hits hard and fades. Domestic-sized electric heaters hold fewer stones and recover more slowly, so the steam is gentler and the room evens out faster. Bigger commercial electric units close most of this gap.
Noise and smell. A wood fire crackles, and the room smells faintly of woodsmoke. People who prefer wood-fired are usually describing this more than the heat.
Consistency. Electric wins. It's the same temperature at 7am on a Tuesday as it is on a Saturday afternoon. A wood stove drifts depending on who last fed it.
Where it can go. Wood-fired needs a flue and clearance, which is why they're in yards, farms and parks. Electric is why a sauna can exist inside a leisure centre or a hotel basement.
What doesn't differ
The heat itself, in the way that matters to your body. 85°C is 85°C. If your reason for going is the hot-cold cycle and how you feel afterwards, both do the job.
Which is which in Bristol
Wood-fired: Bristol Sauna Yard, Ardagh, Orchard Sauna, Fire & Ice at both sites, Bristol Wild Sauna, Stone & Steam, Unfold, Wildplunge, Briery Wood, Field Trip, The Mendip Sauna.
Electric: Bristol Community Sauna, Suvi, The Conscious Breath, and every hotel, gym and leisure centre on the list.
Note that two of the best-regarded community saunas in the city, Bristol Community Sauna and Suvi, are both electric. That tells you most of what you need to know about how much it matters.
The practical answer
If you're going once, go for setting and price, not heater type. If you're going weekly through winter and you've come to enjoy the ritual of it, you'll probably drift towards wood-fired, and Bristol has plenty of it.
