We want to create a relaxing experience for everyone, so here are our top tips for respectful sauna etiquette.
Read the entire article
Always start your wellness day with a shower to prevent any unpleasant odours when you start to sweat. You should also shower after using the toilet.
Respect the dress code: wear a fitted swimsuit, bikini or swim shorts in the swimwear section and go nude in the nude section.
Make sure your entire body fits on your towel to protect the wooden benches and to keep them clean and dry for your fellow sauna-goers.
Keep a comfortable distance between yourself and other guests.
Listen to your body: if you get too hot, leave the sauna quietly.
Take time to cool down and make sure you drink plenty of water between sauna sessions.
Respect the silence: everyone comes to our wellness centre to relax.
Treat our staff and your fellow sauna-goers with respect.
Leave your phone at home or store it in a locker. We have a no-phone policy at our wellness centre to ensure the privacy of our guests.
Last but not least: intimate physical contact is strictly prohibited, and so is any form of sexual harassment. Those who fail to comply will be denied access to our saunas in the future.
