Finnish sauna wood is designed to withstand high temperatures and changing humidity, but regular care is essential to keep your sauna clean, comfortable and looking its best.
The good news is that sauna maintenance is simple. A few basic habits after every session, combined with regular cleaning and an annual inspection, can keep the timber in excellent condition for years.
After Every Sauna Session
The most important part of sauna maintenance is allowing the wood to dry properly.
Let the sauna dry
After using the sauna, allow the room to ventilate and dry completely. Remove wet towels and seat covers and do not leave moisture on the benches.
Good ventilation is particularly important in Cyprus, where the surrounding climate is warm and many private saunas are located next to swimming pools or outdoor areas.
Wipe the benches
After the sauna has cooled, wipe the benches with a clean, slightly damp cloth.
Avoid pouring water over the benches or leaving them wet for long periods.
Use a towel
Using a towel on the bench helps protect the wood from sweat and moisture.
If the sauna is next to a swimming pool, avoid sitting directly on the timber in wet swimwear. Pool water and chemicals can affect the appearance of the wood over time.
Cleaning Sauna Wood
Sauna benches and other wooden surfaces should be cleaned regularly, depending on how frequently the sauna is used.
Use a soft cloth or soft brush together with a cleaning product specifically designed for sauna wood.
Avoid:
-
Bleach and aggressive disinfectants
-
Strong household cleaners
-
Pressure washers
-
Excessive amounts of water
The aim is to clean the timber without saturating it with moisture or damaging its natural surface.
For a private sauna used several times a week, a more thorough cleaning every few months is usually sufficient. Frequently used commercial saunas require more regular attention.
Annual Sauna Maintenance
At least once a year, inspect the sauna more carefully.
Check the:
-
Wooden benches and walls
-
Bench supports and fixings
-
Sauna ventilation
-
Heater and control system
-
Sauna stones
-
Areas showing stains, cracks or excessive wear
Wood naturally expands and contracts with changes in temperature and humidity, so bench fixings may need to be checked and tightened over time.
Sauna stones should also be inspected and replaced if they are cracked, crumbling or significantly deteriorated.
Does Sauna Wood Need Oil?
Not necessarily.
Some sauna timber is left untreated, while other surfaces can be treated with products specifically designed for sauna interiors.
Always follow the recommendations for the particular type of wood and finish.
Do not use ordinary furniture oils, varnishes or wood treatments unless they are specifically approved for sauna use and high-temperature environments.
What Should You Avoid?
A few simple rules will help protect the timber.
Do not pressure-wash the sauna.
Too much water and pressure can damage the wood and force moisture into areas that are difficult to dry.
Do not leave wet towels on the benches.
They prevent the timber from drying properly.
Do not dry clothes inside the sauna.
A sauna is not designed to be used as a drying room, and this can create a fire risk.
Do not exceed the heater's recommended temperature.
Always follow the manufacturer's operating instructions.
Natural Changes in Sauna Wood
Wood is a natural material and will change over time.
Heat, humidity and repeated heating and cooling cycles can gradually change the colour and texture of the timber.
Slight darkening or changes in surface appearance are normal and do not necessarily indicate a problem.
Proper maintenance does not mean preventing the wood from ageing. It means protecting it from unnecessary moisture, dirt and damage while allowing its natural character to develop.
When Does Your Sauna Need Professional Service?
Contact a sauna specialist if you notice:
-
Persistent moisture or condensation
-
Strong or unusual smells
-
Cracked or damaged timber
-
Loose benches
-
Ventilation problems
-
Heater or control system issues
-
Damaged sauna stones
Early maintenance is usually much easier than repairing a problem after it has developed into a larger issue.
