Many thanks to Sanitär Koster AG We would like to sincerely thank Sanitär Koster AG for the excellent work they did during the renovation of our house in Uetikon am See. Inside, all plumbing installations were professionally and meticulously renewed. New pipes, fixtures, and sanitary fittings were expertly installed and seamlessly integrated into the existing structure. The bathroom and toilet now shine with renewed splendor and impress with their functionality and high-quality workmanship. Mr. Koster and his team worked reliably, efficiently, and with great skill. The collaboration was always pleasant and solution-oriented – we felt we received excellent advice and support. A big thank you for the outstanding work. We would gladly use their services again! Sincerely, O. Strauss
Our reliable partner for heating systems for years. Fast, transparent, and fair.
Excellent company with top-notch staff.
Not really recommended (barely 3 stars! And only because everyone can have a bad day). The installer was polite, but he initially installed the single-lever mixer incorrectly. Now both are installed, but one is loose. What a shame! According to the installer, the design of the single-lever mixer is to blame, which I don't find entirely convincing.
was very satisfied
From consultation to execution, everything went smoothly. Costs were adhered to.
