Bathwater - Safe water for bathrooms & showers
Valmonas Analytik AG offers comprehensive microbiological testing for shower, bath and wellness facilities – in accordance with the requirements of the Drinking Water Ordinance and relevant ISO standards .
Our goal: Hygienic safety for bathers, patients and users.
Warum Badewasseruntersuchungen wichtig sind
Water in swimming pools, whirlpools, wellness areas, or showers can be a breeding ground for microorganisms. Especially at elevated temperatures or with aerosol formation (e.g., in hot tubs, steam rooms, showers), there is a risk from germs such as Pseudomonas aeruginosa or Legionella .
Regular analyses ensure:
Legal certainty (legally compliant audits)
Health protection (avoidance of infection risks)
Quality assurance for operators
Our microbiological tests
We analyze your bath water for the following parameters:
Aerobic, mesophilic bacteria
Escherichia coli
Enterococci
Pseudomonas aeruginosa
Legionella spp.
The selection of parameters depends on the type of water and the usage scenario, for example:
Swimming and bathing pool water
Baths with biological water treatment
Bubble baths / whirlpools with > 23 °C and aerosol formation
Steam baths
Shower facilities
