FORTYSEVEN Wellness-Therme, Switzerland

Modern thermal bathing in Baden’s historic spa district

FORTYSEVEN is a large, design-forward thermal complex on the Limmat in Baden, built for people who want a full day of warm water without guesswork. You soak in managed indoor and outdoor pools, then add sauna rounds or the site’s “Kosmos” sensory experience if that’s your style. It’s a controlled facility, so the basics are simple: lockers, clear closing times, and time-based tickets.

What makes it feel different

Baden is a Roman-era bathing town, and the facility leans into that lineage without trying to feel old-fashioned. Switzerland Tourism notes the thermal water here rises at 47°C (about 117°F), a reminder that the source is hot even though the pools are balanced for comfortable soaking.

Good to know before you go

The main baths, saunas, and Kosmos are open daily 08:00–22:00, with last admission one hour before closing and pools stopping 30 minutes before closing. Kids can visit, but the age rules matter, especially for sauna areas.

Where it is
FORTYSEVEN is in Baden at Grosse Bäder 1, 5400 Baden, right in the spa district by the river.

Getting there
This is walk-in access, no hike. The operator notes it’s under a 10-minute walk from Baden train station. There’s also a direct bus option, Bus line 3 from Baden Bahnhof West to the “Grosse Bäder” stop. If you prefer not to think about parking, public transport is the low-stress move.

Parking
Parking is available around the clock in the Bäder multi-storey car park. The operator also notes EV charging in that garage, and suggests nearby overflow garages if it’s busy.

Hours
Bad/Sauna/Kosmos are listed as open Monday to Sunday 08:00–22:00. Last admission is one hour before closing, and bathing ends 30 minutes before closing.

What to bring
Swimsuit for the baths, plus sandals for wet floors. You can hire towels and bathrobes on site if you want to travel lighter. In cooler months, bring a warm layer for outdoor-to-indoor transitions.

This is best for travelers who want a high-comfort thermal baths day near Zurich, with clear hours and plenty of space. It’s also a solid choice in bad weather because you’re not relying on trails or daylight.

Families
Yes, with clear limits. Children are defined as ages 3–15 and are only admitted with an adult. Children under 3 are not admitted. If your plan includes sauna time, note that only children over 12 may enter the swimwear sauna areas (and only with an adult), and the swimwear-free sauna areas are 18+.

Couples and friends
Great for couples who like a steady rhythm: warm water, a rest, then a sauna round. Friends can have a good day here too, just keep the volume down in quieter zones so the space stays relaxing for everyone.

Mobility and access
The operator states the entire facility is wheelchair accessible, which is unusually clear for a wet-floor environment. You’ll still want to plan for slick surfaces and longer indoor walking distances. If you need the easiest route from entry to the calmest pool, staff can usually point you in the right direction once you arrive.

Expectations vs reality
It’s a modern, managed complex, not a quiet mountain bath. Go early if you want the calmest version.

Heat pacing keeps the day comfortable
Do the visit in rounds. Ten to fifteen minutes in hot water or sauna, then a real break. Warm water can make you feel fine while you’re slowly overheating. If you feel dizzy, headachy, or unusually tired, get out, cool down, and drink water.

Kids and heat
Children tire faster in thermal settings. Shorter soaks, more breaks, and a firm “out of the water to rest” routine keeps it pleasant. If a child looks glassy-eyed or cranky, call it early.

Slips are the most common real injury
Wet tile, steps, and outdoor transitions are where people get hurt. Wear sandals, walk slowly, and keep one hand free for balance. If you’re carrying a phone and a drink, it’s fine to make two trips.

Sauna rules are part of safety
FORTYSEVEN separates swimwear sauna areas from swimwear-free sauna areas, with stricter age rules for the latter. Follow the posted guidance and choose gentler rooms first. You do not need extreme heat to have a good day.

Shared-space etiquette
It goes best when everyone shares space and keeps things moving. Don’t block steps or jets, keep personal items tidy, and lower voices in calmer corners. Photos are easiest when you keep other guests out of frame.

Kind cautions
If you’re pregnant, heat-sensitive, or managing cardiovascular concerns, keep sessions shorter and skip strong hot-to-cold contrasts. A gentler pace usually feels better here.

What are the opening hours?

The main Bad/Sauna/Kosmos areas are listed as open daily 08:00–22:00. Last admission is one hour before closing, and bathing ends 30 minutes before closing.

Can children visit?

Yes. Children ages 3–15 are admitted only when accompanied by an adult. Children under 3 are not admitted.

Are there sauna age rules?

Yes. Only children over 12 may enter the swimwear sauna areas (with an adult), and the swimwear-free sauna areas are for guests 18+.

How do I get there without a car?

The operator notes it’s under a 10-minute walk from Baden train station, and Bus line 3 runs from Baden Bahnhof West to the “Grosse Bäder” stop.

Is it wheelchair accessible?

The operator states the entire facility is wheelchair accessible. Wet floors are still part of the environment, so plan traction footwear and a conservative pace.
