Integrated and internal wood burners
Log burner hot tubs: a wood-fired stove built into the tub
A log burner hot tub heats its water with a wood stove that sits inside or is built into the tub, so there is no separate heater beside it. It is the most compact way to have a wood-fired soak.

Hi Albertas, as promised, I’ve attached some photos of our Hot Tub. We’re not on Facebook or the other social media platforms, but we’re happy for you to use any you might want for your website. It arrived Friday morning 4th April and we were in the water and enjoying it on Saturday evening. We’ve been in it every night since! A big thank you to you and your team. The specification is exactly as planned, and the workmanship is excellent. You might welcome some feedback on a couple of relatively minor issues, which I hope you will find helpful. We only received 4 pictures of the hot tub, but in all honesty, these weren’t really enough for us to confirm that we would be happy with the product before making the final payment. We trusted the process and made payment, but it would have been better if we could have seen images of the liner and also inside the electric cupboard and the insulation. Just something to be aware of. The other minor point relates to the sand filter and UV-C. both of them came with European plug fittings that required changing. I would have thought that a UK specification would come with a UK plug. Again, this is not a huge point, but it was inconvenient to have to change these. Apart from those minor niggles, everything was great. So, once again, a big thank you to you and your team. Best of luck and continued success in the future.

Review and installation photos →Hi, We have managed to install our hot tub, and this weekend was our first use! The hot tub is exactly what we wanted, looks fab, heated quickly and stayed warm for ages!
How a log burning hot tub works
The stove is a sealed firebox surrounded by water. You light the fire through a door at the top or side, the hot firebox walls warm the water touching them, and that warm water rises while cooler water flows in from below. This natural circulation needs no pump and no electricity. Smoke leaves through a chimney, which has a guard so bathers cannot touch the hot flue.
There are two main designs. An internal stove sits fully inside the tub behind a timber or metal guard. An integrated stove is built into the tub wall, so the firebox is in the water but the door is reached from outside. Both heat efficiently because almost all of the fire’s heat goes straight into the water.
Log burner inside the tub or an external heater?
| Internal or integrated log burner | External wood-fired heater | |
|---|---|---|
| Footprint | Most compact: no heater beside the tub | Heater stands next to the tub |
| Seating | The stove guard takes some bench space | The whole bench is free |
| Refuelling | From the tub edge or outside door | Easy, away from bathers |
| Ash and cleaning | Inside or at the tub wall | Kept outside the tub |
| Best for | Small gardens, simple off-grid set-ups | Larger groups, frequent use |
Neither is better in every garden. If space is tight or you want the simplest set-up, a log burner in the tub makes sense. If you want every seat free or plan to refuel while people are bathing, look at the external heaters on our wood fired heater for hot tub page.
Using a hot tub with a log burner
- Fill before lighting. Never light the stove in an empty or part-filled tub; the firebox must be covered with water.
- Use dry, seasoned wood. Wet wood smokes, burns cooler and leaves tar in the chimney.
- Cover while heating. A thermal cover, shaped around the chimney, cuts heating time.
- Stir the water. The top warms first; mix before getting in and check the temperature.
- Keep the guard on. The stove and chimney stay hot; supervise children at all times.
- Let it cool before cleaning. Clear ash once the stove is cold.
Check your local rules on wood burning. In smoke control areas, only approved fuels or exempt appliances may be used; ask your local council if you are unsure.
Choosing your log burner hot tub
Start with size: a two-seater such as the Duo Wood, a compact four-seater such as the Nordic Compact Snorkel or Snorkel Compact, or a larger round tub such as the Core or Deluxe. Then choose the shell: a lined tub is easy to clean, while the Wooden Basic and Thermowood Basic are traditional all-timber tubs. Our main wood fired hot tubs page compares every heating route, and outdoor hot tubs lists the full range.
Log burner hot tub questions
What is a log burner hot tub?
A hot tub heated by a wood-burning stove that sits inside the tub or is built into its wall, so no separate heater stands beside it.
Does a log burning hot tub need electricity?
No. The stove heats the water by natural circulation. You only need power for optional extras such as jets, bubbles, lights or filtration.
Is an internal log burner safe?
Yes, when used as instructed: the firebox is guarded, the chimney has a protective shield and the tub must be full before lighting. Supervise children and never touch the stove while it is hot.
Can I change from an internal to an external heater later?
That depends on the tub. Ask us with your model details; replacement internal and integrated stoves are also sold separately.
