The sauna is the heart of a Finnish home. But if it dates back decades, is waiting for moisture damage to set in, or is simply worn out, it won't raise your home's value — it will lower it.
A good sauna renovation changes the situation permanently. Here is what you should know before making your decision.
What a sauna renovation really costs — and what it brings back
The price of a sauna renovation varies significantly depending on the scope. A light surface renovation can cost a few thousand euros, but a comprehensive overhaul — new bench wood, benches, a stove, quality tiling and waterproofing — typically runs considerably higher.
Yet the question is not just about cost. It is an investment.
- A quality sauna renovation concretely increases the resale value of an apartment — buyers appreciate a functional, modern sauna
- A properly executed moisture structure prevents costly water damage, which can cost many times more than the renovation itself
- An energy-efficient stove and modern heating reduce running costs year after year
- Everyday comfort and home enjoyment increase immediately
A sauna renovation in Helsinki or Espoo is also a clear advantage in competitive housing markets. A well-maintained sauna stands out during viewings and negotiations.
Why a half-finished renovation costs more than one done right the first time
Many people carry out a sauna renovation in phases: first the bench wood, then perhaps the stove, later the tiles. The result is often a disappointment — and the bill comes twice.
When a renovation is done in stages by different contractors, problems easily arise:
- Waterproofing and tiling don't align properly if they are not planned together
- HVAC and construction work overlap poorly, causing delays and additional costs
- Questions of responsibility become blurred — who is accountable if moisture gets into the structures?
- The end result looks inconsistent when materials and work are not coordinated
A sauna renovation carried out all at once, as a complete whole, is both higher quality and more cost-effective in the long run.
Sauna renovation with Metikäinen — construction and HVAC under one roof
Metikäinen has an extensive background in the Uusimaa region, with a team that has over 500 completed projects and more than 40 years of combined experience behind them. The construction trade has been passed down through four generations of the family.
The most important difference from many other operators: construction and building technology are handled by the same partner.
- One contract covers the entire project — no coordination between multiple contractors
- Electrical, plumbing and construction work are planned together from the very beginning
- A turnkey renovation means you receive a finished sauna — not half-completed work
- Clear division of responsibility: one partner is accountable for the entire end result
This is particularly important in sauna renovations, where HVAC work and construction technology are inseparably linked. Metikäinen serves both private households and housing companies in Helsinki, Espoo and throughout the Uusimaa region.
Specialist tiling and moisture safety — the two factors that make all the difference
The value of a sauna comes from the details. And two factors matter more than anything else: tiling and moisture safety.
Poorly executed waterproofing is not visible straight away. It shows up years later — as mould, structural damage and a renovation bill that is many times higher than the original.
- Professionally executed specialist tiling lasts for decades without cracks or grout damage
- Correctly chosen materials withstand the temperature fluctuations and moisture stress of a sauna
- The moisture structure is designed as a whole — not merely as a surface material
- Quality execution also means a visually beautiful end result that enhances the appearance of the home
Metikäinen carries out specialist tiling as part of a broader sauna renovation or bathroom renovation — always as a complete package, never as individual pieces.
