What is a wood-fired hot tub?
The Natural Hot Tub
Originally a Scandinavian/Canadian concept, a wood-fired hot tub offers you a simple, eco-friendly way to enjoy outdoor bathing.
Forestflame wood fired hot tubs combine a durable Western Red Cedar tub with a long-lasting stainless steel firebox and flue.
You simply fill the tub with 2 cubic metres of fresh water, light a wood fire in the totally submersed firebox, which then heats up the water to between 35°C and 40°C.
You can control the temperature by adding more wood and varying airflow into the firebox using the attached regulator.
It couldn't be simpler!

What makes a Forestflame wood-fired hot tub so good?
Place your tub where you want it
Let's face it, a wood-fired hot tub offers the romance of the great outdoors - a magnificent view, a secret dell, a private courtyard.
Being able to site your tub exactly where you want it, regardless of where the nearest plug point happens to be, is one of the great pleasures of a wood-fired tub.
Watching the sun go down from your favourite spot, while luxuriating in the embrace of still warm water, is an experience you will treasure, time after time.
Fresh water - no need for nasty chemicals
There's nothing quite like fresh water to inspire those feelings of being at one with nature.
If you have ever swum in a lake, you'll know exactly what we mean.
So many of you are allergic to the chemicals found in most plastic hot tubs and whirlpools - isn't it time those allergies became a thing of the past?
Fresh water is vital, refreshing and natural.
What's more, when you've finished bathing, the fresh water from your wood-fired hot tub can be used to irrigate your garden without killing the plants!
If you're enjoying the final moments of the sun's ebbing rays on a warm summer evening, the last thing you need is the constant drone of water pump.
With a Forestflame hot tub, all you will hear is the faint crackle of the wood fire, the birds evening chorus and the bubbles popping in the top of your champagne flute.
Peace at last!
Fun for friends and family
It's one thing to enjoy your wood-fired hot tub on a romantic summer's evening, but it's just as much fun when you have a bunch of friends and family around for a session in the tub.
Kids love water and with the correct supervision, a Forestflame tub is ideal for allowing them to gain confidence in a safe, warm and clean environment - no stinging eyes or yucky tastes in a wood-fired hot tub!
Our standard tubs accommodate 6 adults in comfort so there's plenty of room for 8 or more children.

Smaller Tub Now Available!
Due to popular demand we have added a 1.5 metre tub to our range for those who have a smaller space available.
This is a comfortable tub for 2 people and was designed largely for accommodation providers where, space and speed of change-over are major factors.
The capacity is just over half that of the larger tub, with proportional savings of time for filling, heating and draining.
Just £4950 + delivery (includes all the accessories that come with the larger tub)
Frequently Asked Questions
How long does it take to get the water up to temperature?
This varies from Summer to Winter:
In Summer, heating the water from 14C to 34C takes around 1 1/2 hours
In Winter, heating the water from 6C to 40C takes around 3 1/2 to 4 hours.
We recommend that you stir the water occasionally to maintain even heating.
Approximately how much fuel does the boiler require per session?
On average, you should need about 2 bags of dry logs (like those you can get from a petrol station) for a session, with maybe a bit more for winter use.
Can I use other fuels other than wood?
The burner must only be fuelled with dry wood - not fresh sawn, or wet wood. As the boiler is underwater, its surface temperature isn't high enough to burn off excess tar in the burner.
How many adults will fit in the tub comfortably?
Your hot tub will accommodate 6 adults comfortably.
What volume of water does the tub take?
Filled to the correct level 1 to 2 inches above the top of the firebox, the hot tub takes about 1.6 cubic metres of water. The total capacity of the hot tub without the boiler is around 2 cubic metres.
Do you supply a cover for the tub?
Yes, we do supply a cover as an optional accessory at extra cost.
Is the tub noisy when the fire is burning?
No - the fire can be heard giving an occasional gentle crackle, which adds to the romantic atmosphere and ambience of the experience.
Is there a lot of smoke from the flue?
If the fire is managed correctly i.e. lit, then built-up steadily in 2-3 stages to a full firebox, then a minimal amount of smoke is produced. Smoke occurs when there is insufficient heat to burn off gases.
What does the tub need to stand on - do I need a special concrete slab, etc.?
Your hot tub needs a 10' circle (3m) of flat concrete, flagstones, or gravel
How heavy is the tub - will it be OK on my decking?
When full and occupied, your hot tub will weigh about 2 tons. It must therefore stand on a solid base. As long as levels allow tub draining to take place and there is no obstruction to airflow around the base, your hot tub can be sunken, or have decking built around it.
Hot Tub Safety
How hot does the water get?
You vary the water temperature by means of a thermometer and by adjusting the fire with the regulator (air intake). Once the desired temperature is reached, simply close the air intake and the water temperature will not rise noticeably.
Does the base of the tub get slippery?
If dirty water is left in your hot tub, bacteria will form a slippery coating. If the inside of your hot tub is disinfected and cleaned as per instructions, it will always offer a good non-slip surface.
Is there a danger of burning myself on the boiler?
The burner is protected by a fence and you should make no attempt to touch the burner when it is lit. However, any surface underwater will not be hot on brief contact. Sustained contact (excluding water from the surface) may cause a burn.
Does the flue get hot?
The chimney (flue) above the cover board is insulated and timber-clad to avoid danger to users.
How deep is the water when at the correct depth?
Maximum depth inside the tub is 31"(80cm) with an initial fill depth of approx. 25"(65cm) allowing for the displacement of bodies.
Can you fit seating in the tub?
Yes you can fit seating in your hot tub and we recommend low, removable seats. Fixed seating, as fitted by some other manufacturers, tends to make cleaning more difficult.
Hot Tub Maintenance
How frequently do I need to change the water?
Herein lies one of the main differences with plastic spa/jacuzzi use. We recommended that you change the water after 2 close sessions. We do not supply a noisy and unattractive filtration system and so bathers should be clean before entering the hot tub.
Do I need to use any chemicals to keep the water clean?
We suggest you add the stated dose of disinfectant and stir well 1 hour prior to emptying. This avoids bacteria growing in the timber. The disinfectant decomposes in water within 30-40 minutes.
How do I clean the tub?
All accessible parts should be scrubbed while still wet after emptying, or during emptying and rinsed down afterwards.
How do I empty the tub?
We supply you with a tap and hose tail allowing you to water your garden with the hot tub's contents. A drain hole with a plug is provided for total emptying.
How do I clean the ash out of the boiler?
Most people can reach in with a shovel, or scoop, once the embers are cold. You can buy a long-handled dust pan/brush from us as an accessory.
Wood does burn well on a bed of its own ash and so may be used for 4 - 5 fires before emptying.
There is no need to completely empty or clean the burner.
How often will the flue need sweeping?
The flue shouldn't need sweeping. With a good fire and air inlet fully open, the flame may reach the top of the chimney which will stop any build-up of tar and soot inside.
How long would you expect the tub to last?
Cedar is one of the most rot-resistant timbers known. Given good maintenance, the tub should happily last 20 years.
Will the wood fade and do I need to treat it with a protector like my garden furniture?
The wood may fade or discolour over time depending on the location of the tub. You can apply similar wood protector to the one you use on your wooden garden furniture to the exterior of the tub.
Will the wood shrink in a dry summer if the tub isn't used?
Yes, if left empty and without a cover on. We recommend (after draining and cleaning) that you refill to 1-2"(5cm) and fit a cover.
