Home › Bathroom renovations
A renovator asks whether the bathroom price is shown before a quote request, whether the warranty on the work is stated and whether the renovation can be paid in instalments. These decide 50 points out of a hundred.

We scored 7 turnkey bathroom renovation companies on 19 metrics. The key question: does the company state its waterproofing qualifications, warranty and price level clearly before a quote request?
A bathroom renovation is one of the most expensive and riskiest renovations in a home: faulty waterproofing is the most expensive possible renovation mistake, because moisture damage often reveals itself only years later. Therefore the most important thing is to verify the competence of the waterproofing, the warranty and the price level before even requesting a quote. We compared companies doing turnkey renovations by how openly they state these matters.
VTT-certified waterproofing or wet-room qualification mentioned (25), example price or price per square metre shown without making contact (20), renovation stages and schedule described (20), warranty and liability insurance stated (15), business ID (Y-tunnus) shown (10), independent review or references shown (10)
Transparency is 30% of the basic metrics, i.e. 15% of the total points · these metrics make up its 100 points · the full formula and the other pillars
How to read the comparison correctly: Half of the points come from buyer's questions, i.e. things the buyer finds out before deciding. The other half measures how openly the company publishes its prices, terms and contact details. Clear differences in points indicate a genuine difference: one tells you the price immediately, another only after logging in. Close scores should not be read as a ranking order, because every measurement has a margin of variation. The measurement accuracy and the full calculation formula are open in the methodology.
Customer experience is brought into the assessment separately. We also collect customer feedback and customer experiences about companies through separate surveys. The survey results will be added to the overall assessment later.
Who is on the list? Companies doing turnkey bathroom renovations that have their own live site and that operate in several cities or the whole region. Included are operators from the capital region and Uusimaa (Blosius, MPV Saunatehdas, Renowin, LaattaBest, Nemo), Suomen LVI-Rakennushuolto from the Häme and Lahti area, and KYLPY Mestarit from Pirkanmaa. This concerns a full waterproofing renovation, not mere surface coating.
Why is the price rarely visible? The price of a bathroom renovation depends on the floor area, plumbing and electrical work and material choices, so most companies only give a quote. Some (MPV Saunatehdas, Renowin) publish an example price or a range, which shows in the scores. A missing public price is a measurement gap in this category, not a zero.
Every company is measured with the same public formula: half of the points come from buyer's questions and half from basic metrics, which have four pillars: technical quality, transparency, reachability and AI quality score. Ranking cannot be bought, and you can see the origin of each point on the company's profile. Read the full methodology →

Waterproofing of wet rooms may only be done by a qualified contractor. A certified wet room work supervisor is a person with verified competence for this; it reduces the risk of moisture damage.
Yes, a household tax deduction can be claimed on the labour portion. The deduction is personal, so spouses can each receive it.
