It's like everything, you have a dream and you want to make it come true. And if you still visit the sauna in Finland. You want to have a Finnish sauna at home.
The Finnish sauna is characterized by very high temperature and humidity. It is heated by conventional or electric stoves, which are equipped with lava rocks. Due to their watering, steam is released into the air. The temperature in this sauna exceeds 90 degrees.
A game with space and prize
You are facing a decision, where to build a sauna? Outdoor or indoor? I had an outdoor project, but I built the inner. Why? The outdoor sauna is significantly more expensive (definitely 2x). You have to reckon with the roof, rest room, shower, electricity supply, sidewalk to the sauna, etc., and so the project gradually becomes more complicated. In the indoor sauna, you build such a larger "cabinet" for electricity. If you have a home where:)
But where with the big "closet" in the house? The sauna doesn't have to be huge, but comfort matters. I have a sauna about 2x2x2 meters in size and can fit in comfortably 6 people and stoves. It is built to measure and the carpenter helped me a lot with it. I placed it right next to the exit on the terrace. Close to the hardening pond.
Note. The sauna is not at home with us, but in our nearby guesthouse, which is actually also our home
You don't have a carpenter? You can also buy a sauna on a turnkey basis and fold it at home. There are plenty of offers and sizes.
What you need to solve in advance?
Connection of electric stoves to a sufficient electricity supply, preferably a three-phase cable. I have cable 5×4 CYKY has 25 circuit breaker (electrician plugged in in an hour)
What sauna elements do you need for construction?
Sauna electric stove - for a classic sauna we count on the required power of 1kW per 1m3 of sauna space. I have a 9kW stove. Lava stones are bought separately.
Control unit (control) – I have digital with the option to automatically set the shutdown time, offered by the stove manufacturer
Sauna door - I have glazed
Mineral wool 40mm or 60mm - I have insulation 40 mm
Alu tape and Alu foil – The foil is used to reflect heat back into the sauna
Ventilation grille (sauna ventilation after switching off)
Silicone cable 5×2,5mm (display and thermometer connection)
and then various bucket accessories, light, thermometer ….
What material does a carpenter need?
Nordic spruce decks for interior and exterior sauna trim. I have floorboards the size of 14 mm, width 95 mm.
Construction prisms - I have 40mm x 60mm
Alder laths for benches, grate on the floor and playpen around the stove. Why alder? It must be a type of wood, which does not release bad luck and is pleasant to sit on (does not make chips) and also has low thermal conductivity
Layer sauna arrangement:
(picture: layer drawing )
Outer casing – floorboards
Insulation layer - special mineral wool is used. Good insulation will allow, that the stove quickly heats up the sauna, for me for 40 minutes
ALU foil – this layer reflects part of the thermal radiation, which did not swallow the decks, back to the sauna
Construction prisms – structural spruce wooden prisms are used, from which a wooden structure supporting the inner cladding is created
Sauna interior cladding - sauna boards
a nearby rest room with a shower or an exit outside will make it easier for the sweaty to get cool and fast
outdoor cold habitat, This is a joy after a sauna (note:. How to build an outdoor pond in another issue of PDČ)
if you build the sauna on smooth tiles, easy to wipe
Quality stainless steel screws, at the bench nicely carved under the surface of the batten, so they don't burn you while sitting
Ventilation and humidity. At the end of the sauna, the sauna door and the ventilation grille open. The generated heat can stay in your house or you can connect the ventilation via a fan, for example, from an outdoor greenhouse
We sauna regularly with children and friends. It's one of my dreams.
See you in the sauna
