Safety & Etiquette
Safety and Etiquette at Borde Therme Bad Sassendorf
Borde Therme Bad Sassendorf is generally safe to visit, with the standard precautions that apply at any brine thermal facility. Wet and slippery surfaces around pool edges, sauna cabin steps, and changing area floors are the most consistent risk. Wear grip sandals throughout, walk slowly near pool entries and outdoor sauna paths, and keep one hand free when moving between areas. In cooler weather the outdoor sections can have slippery paving, so take particular care during autumn and winter mornings.
Brine water at 32 to 33 degrees Celsius is warm enough to promote relaxation but can still cause fatigue over a long visit. Take breaks between soaks, drink water throughout the day, and step out if you feel lightheaded or unusually tired. The brine floating pool at 15 percent salt content creates strong buoyancy. Take time to find your balance when you first enter, and keep brine away from eyes and any open skin irritations. Visitors with cardiovascular conditions, pregnancy, or heat-sensitive health issues should seek personal medical advice beforehand.
Children up to 14 require adult supervision throughout. Keep children's soak time shorter than adults and plan breaks. The house rules state that phone use and photography are generally not permitted, which helps maintain privacy and a quieter atmosphere.
The sauna area follows German textile-free convention. A large towel is needed on all sauna bench surfaces. Aufguss sessions run on a schedule led by staff. Shower before entering any pool or sauna, and keep personal care products out of shared water.
