Why is waterproofing so important?

Waterproofing is the most important structure in a bathroom, protecting floor and wall structures from moisture. It is a mandatory requirement under Finnish building regulations for every bathroom renovation, and it should never be compromised.

Properly done waterproofing prevents water from reaching the structures, which prevents costly moisture damage and mould formation. Professional waterproofing lasts the entire lifespan of the bathroom, typically 20-30 years or longer.

Factors affecting the price

The price of waterproofing depends on many factors. The most important factors affecting the price are the bathroom size, the number of walls to be waterproofed, the number of penetrations, the condition of surfaces, and material choices. Premium waterproofing agents cost slightly more but offer the best protection.

  • Bathroom size: A larger surface area requires more material and labour.
  • Number of walls to be waterproofed: More extensive wall surfaces increase the price.
  • Number of penetrations: Pipes, drains, and electrical installations require careful treatment.
  • Surface condition: Surfaces in poor condition require more preparation work.
  • Material choices: Premium waterproofing agents cost slightly more but offer the best protection.

Tip for those ordering waterproofing

Always request quotes from several renovation companies and compare both prices and the materials to be used. Waterproofing should never be skimped on — it is an investment that pays for itself by preventing costly moisture damage. Also read our comprehensive bathroom renovation pricing guide.
