Seating Capacity – Comfort vs Maximum Numbers
Capacity listings often reflect the maximum number of people who can fit inside, not the number who can sit comfortably.
200 cm Model
The 200cm model is designed to comfortably accommodate three to four adults with adequate personal space. For everyday use, this size provides a relaxed seating arrangement without feeling crowded. While it can host five to six people on occasion, it is best suited for smaller groups where comfort is the priority rather than maximum capacity.
This model is particularly well suited for couples, small families, or households where the hot tub will be used primarily by the same core group of users. Its size make it easier to integrate into terraces, patios, and more compact garden layouts without overwhelming the outdoor space. For properties with limited installation area, the 200 cm model offers a balanced combination of functionality, efficiency, and comfort
225 cm Model
The Amber 225 model is designed to comfortably accommodate five to six adults while maintaining enough personal space for a relaxed experience. For social occasions, it can host up to seven or eight people when needed, making it well suited for gatherings and extended family use.
With its increased diameter, the 225 cm model offers noticeably more interior room, allowing for greater freedom of movement and a more open seating arrangement. This added space can enhance overall comfort, particularly during longer bathing sessions or when the tub is used frequently by larger groups.
If the hot tub will primarily be used by two to four people, the 200 cm model is generally sufficient and more efficient. However, for households that regularly entertain guests or prefer a more spacious interior environment, the 225 cm model provides a clearly more generous bathing experience.
Installation Space
When planning the installation of a wood-fired hot tub, it is important to consider more than just the overall diameter. Proper clearance ensures safe operation, ease of maintenance, and long-term durability.
As a general guideline, allow:
A minimum of 50 cm of clearance around the tub for access and ventilation
Adequate vertical space for the chimney system
Sufficient room for steps and safe entry and exit
The 225 cm model requires a larger prepared base and naturally occupies more visual space. It creates a stronger architectural presence, which can be an advantage in larger outdoor settings. In more compact spaces like terraces, the 200 cm model typically integrates more proportionally and maintains a balanced appearance within the surrounding environment.
Heating Time and Efficiency
Water volume has a direct impact on heating time and wood consumption. The larger the volume of water, the more energy is required to raise it to bathing temperature.
As a general guideline:
200 cm model:
Typically requires approximately 1300L of water and 2 to 2.5 hours to reach bathing temperature, depending on outdoor conditions, starting water temperature, and the type of firewood used.
225 cm model:
Usually requires approximately 1700L of water and 3 to 4 hours of heating to reach bathing temperature under similar conditions.
The larger model contains a greater volume of water, which naturally increases both fuel consumption and preparation time. For customers who value faster heating and overall efficiency, the 200 cm model offers a practical advantage. For those who prioritize interior space and comfort over heating speed, the 225 cm model may be the more suitable choice.
Base Requirements and Weight
A filled wood-fired hot tub can weigh between approximately 1,400 and 2,000 kg, depending on model and water level.
The 225 cm model, due to its greater volume, places higher load demands on the base structure. Reinforced concrete is ideal for both sizes. If installing on decking or elevated structures, load capacity should always be verified.
Operating Costs Over Time
Both models operate using the same heating system and are constructed from the same materials. The primary difference lies in water volume. Due to its larger capacity, the 225 cm model will naturally require:
On average 10 – 20kg more firewood per heating cycle compared to 200cm models
~ 400L higher water consumption when filling
Usualy takes 1 – 1.5h. longer to achieve bathing temperature.
While the difference in operating costs is not significant for occasional use, it becomes more noticeable with frequent heating. For customers planning regular use, this is an important factor to consider when choosing between the two sizes.
Making the Right Decision
Choose the 200 cm model if:
The tub will primarily be used by two to four people
Faster heating time is important
Installation space is limited
Efficiency and lower water volume are priorities
Choose the 225 cm model if:
You regularly host larger groups
Interior space and seating comfort are a priority
You have sufficient installation space
Longer heating time is not a concern
Having determined the right size, you are welcome to explore our Amber models and review their full specifications and included features.
Both sizes are built using the same materials, heating system, and construction standards. The difference is not in quality, but in capacity and operational characteristics.
If you are uncertain, consider how the hot tub will be used on a regular basis rather than on occasional events. Choosing a model based on realistic, everyday use will ensure greater long-term satisfaction.
