Creating Your Home Sauna: What You Need to Know
Building a home sauna is more achievable than most people realise. Whether you're looking at a compact barrel sauna for the garden or a modular indoor cabin for a spare room, the fundamentals remain the same: proper insulation, effective ventilation, appropriate heating, and quality timber. What changes is how these elements are configured for your specific space.
For many homeowners, an indoor home sauna makes sense when space inside the property allows—basements, ensuite bathrooms, or converted utility rooms all work well. Indoor installations typically use electric sauna heaters due to simpler wiring and ventilation requirements, and can be finished to match your interior aesthetic using species like aspen or alder.
Outdoor home saunas offer a different experience entirely. A garden sauna provides spatial separation from the main house—useful for creating a dedicated wellness zone—and often requires less structural work since it's a standalone structure. Outdoor sauna cabins and cube saunas come in various sizes and can be specified with either wood-burning heaters or electric options depending on your preference and available power supply.
The choice between indoor and outdoor often comes down to space, access, and intended use. Indoor saunas integrate seamlessly into daily routines and aren't weather-dependent—ideal if you're using your sauna year-round, multiple times per week. Outdoor saunas provide the ritual of stepping outside, which many find enhances the experience—particularly when combined with cold water immersion.
Your Sauna, Your Way
When space is awkward, specific, or simply demands something beyond an off-the-shelf cabin, a bespoke indoor sauna or bespoke outdoor sauna makes sense. Our team designs and installs entirely custom saunas—built in situ using thermo-treated timber, tailored bench configurations, and integrated lighting—so the finished sauna looks and performs exactly as it should for your home.
Bespoke doesn't necessarily mean expensive; it means designed with purpose. We've installed home saunas in converted garages, below-stairs alcoves, garden studios, and rooftop terraces. Each one required specific problem-solving around ventilation, access, drainage, and aesthetics—work that only becomes clear once you properly assess the space.
Building Your Own Home Sauna
Many of our clients build their own saunas, and we support them through every stage. Our complete DIY sauna guide covers everything from framing and insulation to bench construction and heater installation. We supply the same premium sauna timber, glass sauna doors, and LED lighting systems used in our professional installations, along with free consultations to help plan your materials list and answer technical questions.
For DIY projects, we typically recommend starting with clear dimensions and a heating plan. Most home saunas fall between 4-8m³ in volume, which determines your heater size and influences timber quantities. Whether you're cladding walls in thermo aspen or building benches from alder bench boards, we can guide material selection based on your budget and intended finish.
What to Expect: Costs & Benefits
A typical 6kW electric home sauna costs approximately £1.50–£2.00 per hour to run at current UK energy rates, assuming a 30–45 minute heat-up period followed by your session. Larger heaters (8–9kW) increase running costs proportionally, while smaller spaces with efficient insulation require less energy.
Wood-burning saunas have different economics—fuel costs depend on your timber source and how efficiently you run the stove, but many users find them cheaper long-term, particularly if they have access to seasoned firewood. The trade-off is that wood-burning requires more active management: stoking, ash removal, and chimney maintenance.
Health Benefits of a Home Sauna
Regular sauna use supports cardiovascular health, aids post-exercise recovery, and provides a structured environment for stress management. The heat exposure increases heart rate temporarily (similar to moderate exercise), promotes circulation, and encourages deeper sleep when used in the evening. For many, the value isn't just physiological—it's the ritual itself: uninterrupted time away from screens and demands.
Having a sauna at home removes the friction of needing to travel to a spa or gym. The convenience means more consistent use, and consistency is where the compounding benefits accumulate. Whether it's a 15-minute session after a run or a longer weekend ritual, the sauna becomes part of your routine rather than an occasional treat.
The Finnmark Difference
Finnmark was founded by brothers Jake and Max Newport—"The Sauna Twins"—out of frustration with the lack of authentic sauna expertise in the UK market. Today, we're the UK's only "Sauna from Finland" certified retailer, which means every product we supply meets the standards set by the country where sauna is a cultural institution, not just a wellness trend.
We don't operate on the typical retail model. Our team includes sauna specialists, not salespeople. When you call with a question about ventilation rates, timber species, or heater sizing, you're speaking with someone who has designed, built, and used these systems extensively. That knowledge base means better recommendations, fewer mistakes, and saunas that perform properly from day one.
Whether you're purchasing a complete outdoor cabin, commissioning a bespoke installation, or sourcing premium cladding for a DIY build, you're working with a company that has installed hundreds of home saunas across the UK and understands exactly what's required to deliver an authentic Finnish sauna experience.

Barrel Saunas UK: Your Questions Answered
Do I need planning permission for a home sauna?
Indoor saunas typically don't require planning permission as they're considered internal alterations. Outdoor saunas may fall under permitted development rights if they're under 2.5m in height and not positioned too close to boundaries, but it's worth checking with your local authority. Listed buildings and conservation areas have stricter rules.
How much space do I need for a home sauna?
Minimum viable size is approximately 1.2m × 1.5m for a compact single-person sauna, though most people find 1.8m × 2.0m more comfortable. Family-sized saunas typically range from 2.0m × 2.5m to 2.5m × 3.0m. The key is having sufficient headroom (minimum 1.9m ceiling height) and proper bench layout so heat stratification works correctly.
What's better: electric or wood-burning heater for a home sauna?
Electric heaters are more convenient—faster heat-up, precise temperature control, and no ash or chimney maintenance. Wood-burning heaters provide a more traditional experience with a gentler, more humid heat, and appeal to those who enjoy the ritual of fire tending. For indoor home saunas, electric is almost always more practical due to ventilation and installation simplicity.
How long does a home sauna take to heat up?
Most electric saunas reach 80°C in 30–45 minutes depending on room volume and insulation quality. Wood-burning heaters take 45–60 minutes typically. Pre-heating is part of the routine, and many people use this time to stretch, shower, or prepare the space.
What maintenance does a home sauna require?
Regular cleaning (wipe down benches after use), periodic deep cleaning of timber surfaces, and occasional treatment with sauna-safe cleaning products. Electric heaters need sauna stones rearranging and replacing every 1–2 years. Wood-burning stoves require ash removal and annual chimney inspection. Properly maintained saunas last decades.
Will a home sauna add value to my property?
A well-designed, professionally installed sauna is generally viewed as a premium amenity, particularly in higher-value properties. Estate agents report that wellness features appeal to health-conscious buyers, though like any home improvement, ROI depends on your local market and overall property positioning.
