The scope of sauna renovation can vary greatly depending on the object. It can mean everything from minor surface renewal to complete renovation of the entire sauna space. Typically, renovation includes at least the following stages:
Demolition and Preparatory Work
Dismantling old sauna structures - removing benches, removing wall and ceiling panels, and possible removal of old flooring material (e.g., vinyl mat or tiles). At the same time, base structures are exposed and it's checked whether moisture has penetrated the structures.
Installation of New Finishing Materials
The sauna's appearance is renewed by installing new wall and ceiling panels and benches. The material chosen is usually heat and moisture-resistant wood (such as aspen, heat-treated alder, or spruce), which creates the desired atmosphere. Benches are custom-made according to the space's dimensions, and their placement and height are planned with usage comfort in mind.
Heater Replacement
The old heater is replaced with a new, efficient model. In Lappeenranta, many have electric heaters especially in city homes, while wood-fired heaters are preferred in cottage saunas. During renovation, a heater suitable for the space (with the right power and desired heating method) is selected and fire-safely installed in place. At the same time, heater stones and protective walls are renewed if necessary.
Electrical Work and Lighting
During renovation, the sauna's electrical system is updated to modern standards. Old fixtures are replaced with modern sauna lights suitable for humid and hot conditions - for example, LED strips under benches or fiber optic lights in the ceiling create atmosphere. All electrical connections, wiring, and possible control panels are installed by a professional in accordance with electrical safety requirements.
Ventilation Improvement
Good ventilation is an essential part of a functioning sauna. During renovation, ventilation openings can be added or enlarged and it's ensured that replacement air circulates correctly. If necessary, an exhaust valve is installed or the existing ventilation system is adjusted so that the sauna dries quickly after use.
Insulation and Waterproofing
If deficiencies in insulation or moisture damage are discovered during the demolition phase, the sauna's thermal insulation and vapor barrier (waterproofing) are renewed according to modern building codes. This is especially important if the sauna is located next to a wet room (e.g., next to a bathroom), so that moisture doesn't penetrate the structures. A professional ensures that waterproofing is done correctly and tested before surface installation.
All these work stages are carefully executed in the correct order. First, the new sauna is planned and dimensioned, then necessary demolition work is performed, and finally construction and finishing. The result is a renewed sauna that looks good, functions flawlessly, and is safe to use.
A smaller surface renovation (for example, only replacing benches, panels, and heater) can be completed in a few days, while a larger sauna renovation in Lappeenranta - which also includes renewing insulation and electrical systems - can take from a couple of weeks to a month depending on the object's requirements. A professional can give an estimate of duration in advance, and a well-planned project progresses smoothly from start to finish.
