Safety & Etiquette
Fonteverde Tuscan Resort and Spa Safety Tips
Fonteverde Tuscan Resort and Spa is a fully managed spa with trained staff and medical personnel on site, making it safer than unmanaged natural springs. The spring water enters the pools at 42 degrees Celsius, cooled to around 37 degrees in the main pool. Standard precautions apply: those with cardiovascular conditions, respiratory disorders, low blood pressure, or recent surgery should seek medical clearance before bathing. Pregnant women should consult their doctor before using thermal pools or spa facilities.
Swimwear is required. Bathrobes and slippers are included in the pool entry fee; towels are available as a supplement. Shower before entering pools. Avoid eating for an hour before thermal treatments. Stay well hydrated throughout, as thermal water causes fluid loss even at lower pool temperatures.
The Bioaquam circuit uses whirlpool jets, cold water elements, and a waterfall with strong pressure jets. Visitors with neck, back, or recent injury conditions should inform staff before entering. The circuit is designed for alternating warm and cool immersion; those with heart conditions should check with the on-site medical team before using it.
Advance booking for all treatments is strongly recommended, and day visitors should pre-book pool access during high season and on weekends. Pool capacity is actively managed to preserve the experience for all guests. Check the thermal spa website for current opening hours and rates before travelling, as the day spa and hotel pool have separate booking channels.
