Sauna Etiquette in Porto — What to Expect

What to Wear

Every sauna in Porto requires a swimsuit in shared areas — no exceptions. This applies to Finnish saunas, hammams, steam rooms, and infrared studios alike. If you're coming from Germany or Finland, where saunas are traditionally textile-free, this will feel different. In Porto, it's non-negotiable.

Most venues provide towels, but not all. Hotel spas like Mandalay Spa Liberdade include robes and slippers as part of the experience — a nice touch that makes the visit feel more premium. At standalone venues like The Hot Cold Club or Vidnova, you'll want to bring your own flip-flops.

Pack list: swimsuit, flip-flops, a water bottle, and a hair tie if needed. Leave valuables in the locker — every venue provides them.

Finnish Sauna Etiquette

Porto has several excellent Finnish saunas, and the etiquette is straightforward. Sit on your towel — never directly on the wooden bench. This is both hygienic and expected. Sessions of 10 to 15 minutes are typical, followed by a cool-down period outside the sauna. At contrast therapy venues like The Hot Cold Club, that cool-down means an ice bath. At Healthy Horizon, you can use cold plunge pools between rounds.

Three rounds of heat and cool-down is the sweet spot for most people. Don't feel pressure to stay in longer than feels comfortable — nobody is judging you for stepping out after eight minutes.

A few specifics: don't pour water on the stones unless the venue explicitly allows it (some do, some don't). Keep conversation low. And if you're at a busy venue, be mindful of space — don't spread out across two seats when others are waiting.

Hammam Etiquette

The Oriental Spa is Porto's only dedicated hammam, and the experience is entirely different from a Finnish sauna. It's attendant-led, which means you don't need to know much — just show up, change into your swimsuit, and let the therapist guide you through the ritual.

The traditional hammam sequence involves warm steam to open your pores, followed by black soap application and vigorous exfoliation with a kessa glove. It can feel intense the first time, but that's the point — the exfoliation is remarkably thorough. After the scrub, you'll rinse and relax in the warm room.

The main thing to know: just relax and follow the therapist's lead. They've done this thousands of times. If the pressure is too much, say so — they'll adjust immediately. Couples sessions are available if you want to experience it together.

Hotel Spa Etiquette

Porto's hotel spas — Sayanna Wellness & Spa, BSpa by Karin Herzog, The Vintage Porto Spa, and others — are open to non-guests, but they run on a different rhythm than standalone saunas.

Book ahead. This isn't optional for hotel spas, especially on weekends. Day visitor spots are limited, and showing up without a reservation usually means being turned away.

Arrive 10 to 15 minutes early. Check-in involves paperwork, a locker assignment, and sometimes a brief orientation. If your spa circuit is time-limited, the clock starts at your booking time — not when you actually get to the sauna.

Respect phone-free zones. Most hotel spas in Porto enforce a no-phone policy in wet areas and relaxation rooms. Leave your phone in the locker. The quiet relaxation rooms — with heated loungers, dim lighting, and herbal tea — are meant for actual relaxation, not scrolling. It's one of the best parts of the experience if you let it be.

Tipping in Porto Spas

Portugal doesn't have a heavy tipping culture, and spas are no exception. Here's the general rule:

For treatments (massages, hammam rituals, facials): a tip of €5 to €10 is appreciated but not expected. If the therapist was exceptional, it's a nice gesture. Hand it to them directly at the end of your treatment.

For self-service spa circuits: no tip is expected. You're using the facilities independently, and the staff maintaining the venue are salaried. This applies to most visits at places like BluSpa Jupiter Porto, El Spa at Melia Porto, or Core Collective.

Don't feel awkward about not tipping — it's genuinely not the norm in Portugal for spa circuit access.

General Tips

Hydrate before, during, and after. Porto is warm, and dehydration hits faster than you'd expect. Drink at least a glass of water before your session and another after. Most venues have water fountains or offer water and tea. If you're unsure about dehydration signs, this quick NHS dehydration guide is useful.

Shower before entering the sauna. This is expected at every venue, and there are showers in the changing areas for exactly this reason. A quick rinse removes products, oils, and sweat that would otherwise end up on shared surfaces.

No phones in wet areas. Even at venues that don't explicitly ban them, using your phone in a sauna or steam room is considered poor form. Nobody wants to be in a hammam with someone on a video call.

Start with a gentler option if you're new. If you've never been in a sauna, an infrared session at The Reformer Lab (around 50 to 60 degrees) is far less intense than a Finnish sauna at 85 to 88 degrees. It's a good way to ease in, and this Harvard Health sauna safety overview is a useful primer before your first session.

Go on a weekday morning. Every venue in Porto is quieter before noon on weekdays. You'll have more space, less noise, and a better experience overall.
