When calculating the total budget for a sauna, it’s important to consider several key factors that can make the price vary significantly. Here we explain the most relevant ones:
Outdoor saunas, for example, usually require additional work like a solid foundation or protective covering, while indoor ones must adapt to available space and ensure adequate ventilation.
The larger it is, the more materials will be needed and the greater the heater power required, which translates to higher cost.
The quality and type of wood used affects both price and comfort and durability. Woods like Nordic spruce, red cedar, or heat-treated wood offer excellent properties for heat conservation, humidity resistance, and providing a pleasant experience.
The type of heating you choose directly influences initial cost and subsequent energy consumption. Each option has its advantages: wood provides a traditional and authentic atmosphere; electricity offers greater convenience; and infrared provides faster and more energy-efficient heating.
Elements like LED lighting, Bluetooth speakers, aromatherapy kits, decorative volcanic stones, or special thermometers can slightly raise the price but greatly enrich the experience.
Factors like installer availability, local demand, or even climate can influence total cost. In colder regions, for example, it may be advisable to reinforce insulation, which implies a small budget increase.
Before installing the sauna, some adaptations may be necessary, such as leveling the ground, preparing the base with concrete slab or decking, incorporating an electrical outlet, or reinforcing insulation.
Before installing a sauna, it’s essential to consider several practical aspects that will ensure efficient, safe operation adapted to your home.
Make sure you have sufficient space for the sauna you want to install, whether indoor or outdoor. There must be room not only for the structure but also to allow good air circulation and, in the case of an outdoor sauna, to build a stable foundation.
Some saunas—especially electric ones—may require three-phase current connection. It’s advisable to consult with a professional electrician to ensure your current electrical installation supports the requirements of your chosen sauna.
Adequate ventilation is essential to avoid humidity accumulation and condensation, which contributes to both material durability and interior air quality in the sauna.
Generally, saunas don’t require water connection, except for steam saunas, which do need plumbing installation.
Good insulation not only improves energy efficiency but also accelerates heating time and maintains temperature more stably. It’s a key factor especially in saunas installed outdoors or in cold areas.
Depending on the autonomous community and installation type (especially outdoors), it may be necessary to request a building permit or comply with certain urban planning requirements. Consulting with your city hall will save you from unexpected issues.
The sauna must have protection against fire, humidity, and electrical overloads. Choosing certified products and ensuring professional installation is the best way to enjoy with complete peace of mind.
Once installed, maintaining your sauna in good condition is simpler than it seems. With basic care and intelligent planning, you can enjoy it for many years without complications or excessive costs.
Electricity expense will depend on sauna type, heater power, and frequency of use. Infrared saunas, for example, are usually more energy efficient, while wood-fired ones don’t generate an electricity bill but do require stove maintenance.
It’s recommended to clean the interior regularly, ventilate well after each use, periodically check electrical connections, and treat the wood with special sauna oils. This care extends useful life and maintains the experience in optimal conditions.
With adequate maintenance, a sauna can exceed 15 years of use without problems. Choosing quality materials and correct installation from the beginning is key to guaranteeing longevity.
Although the initial investment may seem high, having your own sauna is much more economical than frequently visiting a commercial spa. In the medium and long term, savings are evident, and you’ll also have the convenience of using it when and how you want.
A sauna not only improves your personal wellbeing but also represents a real improvement in your home:
Installing a sauna is an effective way to increase your property value, which can make the difference compared to other similar homes in the market.
A sauna conveys comfort, luxury, and personal care, making the home more attractive if you decide to sell or rent it in the future.
When considering sauna installation, a common doubt arises: assemble it yourself or hire professionals? The decision will depend on your experience, available time, and budget.
Self-assembly is usually more economical, as labor costs are reduced. However, you must consider that some technical work—like electrical installation or insulation—must comply with current regulations.
Installing a DIY sauna involves basic knowledge of carpentry, electricity, and planning. If you like DIY projects and have time, it can be a very rewarding experience. But if you prefer to ensure everything works perfectly from day one, it’s most advisable to use professionals.
The time it takes to assemble a sauna yourself varies according to type and installer experience. It can take from several days to some weeks.
Hiring experts offers you peace of mind, quality finishes, installation warranty, speed, and efficiency.
Always look for installers with proven experience, ask for references or photographs of previous work, compare budgets, and ensure they use certified materials.
Installing a home sauna is a decision that can transform your quality of life.
Whether you choose a traditional wood sauna, a modern infrared cabin, or a compact indoor model, the result will be a space for relaxation, health, and disconnection.
Multiple options are available adapted to different lifestyles, budgets, and spaces. Remember: the final cost will depend on factors like sauna type, size, chosen materials, and whether you opt for professional installation or DIY assembly.
A well-chosen and well-installed sauna not only improves your physical and mental wellbeing but also becomes a differentiating and attractive element within your home.
Between €2,600 and €6,200, according to size and finishes.
Yes, in the long term, especially if you use it frequently.
Infrared saunas are usually the most energy efficient.
A prefabricated sauna can be installed in 1-3 days. A DIY project can take weeks.
