Buying a wood-fired hot tub – what matters most?
A wood-fired hot tub is a deliberate choice for a slower pace, deeper relaxation, and meaningful time spent outdoors.
Before investing, it is important to consider the full picture: the size, shape, heater type, insert materials, and other details that matter in a long-term purchase. Our guide will help you make a better-informed choice.

Relaxation, wellness and personal value
Warm water naturally helps create a feeling of calm and comfort. It offers something very different from simply sitting on the sofa after work
Personal relaxation
Time with friends and family
Fun for kids
A hot tub can serve very different purposes during the week and at the weekend. When friends come over or the family gets together, it becomes a place to spend time together.
Without screens and everyday noise, real conversations happen more easily, relationships grow stronger, and memories are created that often become the most meaningful part of the investment.
Hot tub and children
We honestly recommend giving children and adults separate time in the hot tub whenever possible. Otherwise, adults may end up spending more time wiping water off their face than relaxing 🙂
No screens
When several children are in the hot tub, they don't need screens or any additional entertainment.
Perfect for birthday parties
Perfect for children's birthday parties and gatherings with several families.
All day fun
Lots of laughter, splashing, and maybe even a bit of diving.
Note: Children should always be supervised by an adult and must never be left unattended in or around the hot tub.
Relaxation from daily life and recovery after work
Time in a hot tub can become part of a simple routine that helps you leave the day behind. It gives both body and mind a chance to settle after work, noise, and constant activity
Pleasant contrast
Sitting in cooler air while immersed in warm water creates a pleasant contrast and a relaxing experience in itself.
Balance and relaxation
Being immersed in warm water helps the whole body relax and creates a sense of balance and calm.
Summer refresh
During summer, you can lower the water temperature and enjoy the hot tub as a refreshing break from the heat.
How to choose the right hot tub?
Here are the key points worth understanding and comparing before you buy
Traditional wooden tub or modern hot tub?
Traditional Nordic hot tubs are round and usually come without jets or LED lighting. The focus is on hot water, quiet time, and sitting together.
Some older Nordic models are made entirely of wood, and the water is drained and refilled each time because there is no filtration system.
Gardenvity offers only modern hot tubs with traditional wood-fired heating. Models are available in round or square shapes, and the seating is always ergonomically designed for comfort.
Wood-fired heating can also be combined with electric temperature maintenance, massage features, lighting, and a filtration system.
Round or square?
Round hot tubs are best suited to shared use and spending time together. They usually do not have clearly defined individual seats, with the massage jet positions loosely shaping where each person sits. If your aim is simply to relax and talk, there is no need to switch the jets on.
They also fit easily into most backyard settings.
Square hot tubs have a more modern look, closer to the jacuzzi style many people know. They also give you more legroom inside the tub.
The corner design allows for more effective massage placement, and some models include a lounger, creating a balance between a classic hot tub and a more massage-focused model.
Integrated stove or external stove?
An integrated stove saves space in the backyard and makes the hot tub look more compact.
You can choose a model where the stove uses part of the inner tub space and creates a raised seating area, or choose the Horizon stove, which keeps the interior flat.
The main advantage of an external stove is that it gives you more choice in power output, although it does take up more space.
In the long term, an external stove is also easier to upgrade or replace, and the connection is straightforward.
Round insert with a raised seat, 4-6 people
Round insert with a raised seating area, inner diameter 180 cm and outer diameter 200 cm, available with two stove options: Standard or Verta
Standard, 30 kW
🔥 Heating time: approx. 2 hours
Verta, 30kW
🔥 Heating time: approx. 2 hours
The Verta heater is a relatively new design on the market. Its main advantage is the larger window, which gives a wider view of the flame. The glass technology also helps prevent it from becoming smoky too quickly, so it stays clearer for longer.
Space saving
The main advantage of this solution is that it saves space in the garden while still providing enough heating power.
Raised seating area
Some people see the raised seating area as a drawback, while others find it very practical.
Best for all
Although it changes the usual seating layout, it is ideal as a place to cool down and refresh yourself.
The picture shows the version with a 180 cm inner diameter, which seats 4–6 people.
When we say 4–6 people, we mean that 4 adults can sit very comfortably, with space for up to 2 children as well — although this is the maximum. When it comes to children, though, they somehow always manage to make room for more. 🙂
Round insert without raised seating area, 6-8 people
Round insert with an inner diameter of 180 cm and an outer diameter of 200 cm, without a raised seating area. Available with either an integrated Horizon stove or an external Octa stove
Integrated stove Horizon, 20 kW
🔥 Heating Time: approx. 3,5 - 4 hours
External stove Octa S, 26 kW
🔥 Heating Time: approx. 2,5 - 3,5 hours
External stove Octa M, 30kW
🔥 Heating Time: approx. 2 - 3 hours
External stove Octa L, 38 kW
🔥 Heating Time: approx. 1,5 - 2 hours
Horizon
The Horizon stove offers a good balance between saving space in the garden and maintaining comfort in a round hot tub. However, it is slightly less powerful than the external stove options.
Octa
The external Octa stove gives you more freedom to choose the power output. If you want the water to heat up as quickly as possible, a higher output is recommended. Keep in mind that this stove requires more installation space.
Square insert with a raised seating area, 4–6 people
Square insert with an inner width of 180 cm and an outer width of 200 cm, available with either the Standard or Verta stove. Seats 4–6 people
Standard, 30 kW
🔥 Heating time: approx. 2 hours
Verta, 30kW
🔥 Heating time: approx. 2 hours
Square Hot Tubs
Browse our pre-configured square wood-fired hot tubs, or explore configurable models.
Modern Look
Square hot tubs are closer in style to the jacuzzi look many people know, while offering a more modern design.
Better Massage Zones
More effective massage systems can be built into the corners, combining classic hot tub use with a more focused massage experience.
Lounger Benefits
The lounger also creates more possibilities for neck and leg massage, making the hot tub more versatile.
Square insert without a raised seating area
Inner width 180 cm, outer width 200 cm, available with either the Horizon or Octa stove. Seats 4–6 people

🔥 Heating Time: approx. 2,5 - 3,5 hours
External stove Octa M, 30kW

External stove Octa L, 38 kW
🔥 Heating Time: approx. 1,5 - 2 hours
Insert choice: Acrylic or fibreglass?
Traditional all-wood hot tubs have largely been replaced by models with fibreglass or acrylic inserts
The main advantages of acrylic and fibreglass:
Smooth surface
Ergonomic seating
Easy to clean
Compared to acrylic, fibreglass surfaces may be slightly more prone to fine scratches. This is normal for this type of material and does not affect comfort or everyday use. Depending on the colour or gloss level, one surface may also appear to scratch less than another, but this is often simply due to the way light reflects off it.
Acrylic inserts are more costly to produce, while fibreglass inserts are generally less expensive
Fiberglass & Osmosis
Fibreglass used to be more closely associated with osmosis issues, but thanks to the use of double protective layers similar to those used in shipbuilding, this is no longer a common problem.
Main Differences
Today, the main difference between fibreglass and acrylic is the choice of colours and finishes. Both materials are available in grey, but acrylic also offers marbled finishes, while fibreglass can have a 3D sparkle effect.
Choosing a colour
For most buyers, the decision is mainly aesthetic — it comes down to which finish and colour you prefer.
Winter-Ready Heating and Filtration
Enjoy the independence of wood-fired heating, added protection from freezing, and a filtration system designed to keep the water cleaner for longer with less maintenance
Key features
Many of our pre-configured models come with Premium filtration as standard, including a built-in 3 kW heater. If you choose a simpler configuration, you can always upgrade and add this feature.
3 kW heater
The wood-fired stove provides natural heating, while the integrated 3 kW heater helps maintain a safe minimum temperature in colder conditions.
Protection against freezing
This combination helps protect the system in winter and keeps the hot tub safer in sub-zero temperatures.
Filtration, Less Maintenance
Premium filtration and effective water circulation help keep the water cleaner for longer, with fewer water changes.
