Buying a sauna: The most important decisions before purchase

When buying a sauna, the first decision is not about design, but about planning. Location, size, stove, material, and budget together determine which sauna will best suit your home in the long run.

The following questions help make clear decisions early on:

• Should the sauna be in the garden, in the house, or in an ancillary room?

• How many people will use the sauna regularly?

• Is a classic Finnish sauna, a compact indoor sauna, or a garden sauna more suitable?

• What requirements arise from the power connection, foundation, or permits?

• What is a realistic budget for acquisition, installation, accessories, and operation?

For an initial market overview, the article: Saunas for Garden and Home, compares different designs, sizes, and applications. To make your decision easier, we will look at the most important points in detail.

Garden sauna or indoor sauna: Which solution suits your home?

The decision between a garden sauna and an indoor sauna primarily depends on the available space. Equally important are privacy, structural requirements, user experience, and desired atmosphere.

Garden sauna: When a sauna in the garden makes sense

A garden sauna fits well if you have enough space outdoors. It creates distance from everyday life and often feels like a private retreat.

This solution is particularly useful for these sauna requirements:

• You desire a natural spa feeling in your own garden.

• The sauna should be planned independently of the living space.

• Larger models, glass fronts, or an antechamber are of interest.

• A foundation, power connection, and permit are available in the garden or can be installed.

The detailed planning for buying a garden sauna is particularly relevant when the location and construction type are already fixed.

Indoor sauna: When a sauna in the house fits better

An indoor sauna is suitable when short distances and discreet use are a priority. Bathroom, basement, or a wellness room can be good options for this.

It is especially suitable for houses with adequate ventilation, power supply, and sufficient room height. Planning an indoor sauna for home should consider these technical points early on.

Compact or spacious? How to choose the right sauna size

A small sauna for home is sensible if space needs to be used efficiently. However, the right size depends not only on square meters but also on seating comfort, lying area, and the regular number of users.

How to realistically estimate your space requirements

The space requirement for the sauna begins with the cabin size but does not end there. Door opening, ventilation, power connection, movement area, and a pleasant cooling area are also part of planning the usable space.

Important questions for choosing the size are:

• Do you mostly use the sauna alone, with two people, or with several people?

• Do you primarily want to sit or also lie comfortably?

• Should the sauna be in the bathroom, basement, garden house, or garden?

• Is there enough distance to walls, furniture, and technical connections?

• Is there enough space outside the cabin for changing and cooling down?

Small sauna for home: When compact models make sense

Compact models are particularly well-suited for clearly defined floor plans. They are suitable for households that sauna regularly but do not plan a large wellness room.

A small sauna cabin is often the right choice if:

• one to two people primarily use the sauna,

• the room is narrow, low, or angled,

• short heating times are important,

• the sauna should be quietly integrated into the home visually.

Planning a small sauna for home is particularly helpful in cramped spaces. For an initial selection, these compact design saunas offer good orientation by size, shape, and effect.

Location in the garden: Clarify building permit, foundation, and subsoil

Before purchasing a garden sauna, the location, building permit, and subsoil for the garden sauna should be checked together. These points determine whether the sauna can be used safely, legally, and comfortably in the long term.

Check garden sauna building permit early

Whether a garden sauna requires a permit depends not only on the footprint. Height, enclosed space, distance to the property line, type of stove, and local regulations can also play a role.

For planning, these questions are particularly important:

• Are there regulations from the state building code, development plan, or municipality?

• Are boundary distances and neighbor rights maintained?

• Does the sauna have a wood-burning stove, chimney, or special technical equipment?

• Is the property located in a protected area or a special development area?

The garden sauna building permit should therefore be clarified before ordering and installation. This way, you avoid later changes to the location or model.

Sauna foundation and subsoil preparation for the garden sauna

A suitable sauna foundation protects the structure from moisture, settling, and tilting. It also ensures that doors, walls, and glass surfaces function properly in the long term.

Sauna wood types, construction, and wall thickness in comparison

Wood for sauna influences the feeling of warmth, scent, appearance, and maintenance effort. Equally important are the construction method and sauna wall thickness, as they co-determine heat storage, stability, and energy consumption.

Important selection criteria are:

• Spruce appears classic, bright, and natural.

• Thermo wood is more dimensionally stable and often more resistant to moisture.

• Dark surfaces like Shou Sugi Ban set strong design accents.

• Thicker wall thicknesses can retain heat longer.

• Clean workmanship reduces warping, gap formation, and maintenance effort.

A comparison of sauna wood types clearly shows these differences. This makes it easier to assess which construction fits the garden, interior, and personal wellness demands.

Choosing a sauna stove: Electric or wood-burning?

A sauna with an electric or wood-burning stove differs not only in operation. The stove influences heating time, atmosphere, operating comfort, installation effort, and ongoing maintenance.

A sauna with a wood-burning stove appears particularly traditional but requires more preparation. Chimney, exhaust system, and inspection should comply with the Chimney Sweeping and Inspection Ordinance.

For comparing the options, a reliable classification of saunas with electric or wood-burning stoves helps. This clarifies which stove suits the location, use, and desired sauna experience.

All costs at a glance: from acquisition to installation and running expenses

Sauna costs are composed of the model, size, construction method, stove, installation, and operation. Those who consider these areas together can realistically plan their own sauna and better avoid later additional costs.

Sauna costs: Which cost areas are important

Acquisition is only one part of the total cost. Delivery, assembly, electrical connection, accessories, and regular electricity consumption are also part of budget planning.

Important cost areas include:

• Sauna cabin or sauna house

• Sauna stove and control unit

• Delivery and installation

• Power connection or preparation for a wood-burning stove

• Accessories such as infusion bucket, thermometer, lighting, and loungers

• Ongoing energy and maintenance costs

What additional costs can arise with a garden sauna

With a garden sauna, site-related expenses often arise. These include the foundation, subsoil preparation, permit review, power supply, and possibly garden work.

Garden sauna costs depend particularly heavily on location, size, and features. A clear cost framework helps to balance comfort desires and investment.

The path to the right sauna: What matters when buying

Anyone looking to buy a sauna benefits from a pre-selection in the sauna shop. Based on location, size, wood type, stove, and budget, the right model can be narrowed down much more effectively.

For the final selection, these points are particularly helpful:

• suitable construction type for garden, house, or compact rooms

• realistic size according to user number and comfort requirements

• suitable stove with appropriate technical preparation

• harmonious wood type, wall thickness, and features

• transparent planning of delivery, installation, and operation

A sauna configurator can provide additional guidance if dimensions, features, and design need to be individually coordinated. For a structured selection, buying a sauna offers a suitable introduction to various models for garden and home.

Frequently asked questions about private saunas

Which sauna fits better, garden or interior?

A garden sauna is a better fit if there's sufficient outdoor space and you want to create your own wellness area. It offers more distance from everyday life and often greater design freedom. An indoor sauna is suitable if short distances, weather-independent use, and discreet integration into the house are more important. Ceiling height, ventilation, and power supply are crucial.

What should you consider before buying a sauna?

Before purchasing, the location, size, stove type, wood, wall thickness, and budget should be clarified. These factors determine which model will permanently suit the house or garden. Technical requirements such as power connection, foundation, and possible permits are also important. The sooner these points are checked, the more reliable the planning will be.

Does a garden sauna always require a building permit?

No, a garden sauna does not always require a building permit. The regulations depend on the federal state, municipality, size, location, and features. Boundary distances, development plans, chimneys, or special property situations can also be relevant. Therefore, it is advisable to check with the responsible building authority before ordering and installing.

How much space does a small sauna for home need?

A small sauna doesn't just need space for the cabin itself. Door opening, ventilation, power connection, movement area, and a cooling-down area should be planned for. For one to two people, a compact model is often sufficient. More comfort is achieved if seating, reclining, and changing are not planned too tightly.

What is the total cost of owning a sauna?

The total cost depends on the model, size, construction, stove, delivery, installation, and operation. The pure purchase price therefore only forms part of the budget. For a garden sauna, additional costs may arise for the foundation, subfloor, power supply, permit review, and garden work. Accessories, maintenance, and energy consumption should also be taken into account.
