How to Book a Beer Spa in Prague

A friend tried to explain the Prague beer spa to me over dinner. He got to “you sit in a tub of beer” and I stopped him, because surely that was the whole thing. It wasn’t. The tub is warm beer and herbs. There’s a tap of cold Bernard lager next to it. And the whole thing lasts 90 minutes.

This guide covers how to book a Prague beer spa: the three most-reviewed options, what the treatment actually involves (hops, malt, warm beer, and yeast all go in the bath), and the practical things — what to wear, whether you can really drink unlimited beer while bathing, and when booking matters.

What a Beer Spa Actually Is

You sit in a wooden bathtub filled with a mixture of warm water, dark beer, hops, crushed malt, and active brewer’s yeast. The temperature is about 34-36°C — warm enough to relax in, cool enough that you don’t cook yourself. You soak for about 20-25 minutes, then move to a warm straw bed or a salt cave for another 15-20 minutes, and then to the massage or rest stage depending on what you booked.

The claimed benefits are standard wellness rhetoric: the hops and yeast “feed the skin,” the warm water and carbonation improve circulation, the enzymes help tired muscles. The actual benefit is that it’s genuinely pleasant. Warm water, dim light, the smell of hops, and beer you can drink for an hour. Very few spa treatments let you drink while you take them.

The Drinking Part

Each bathtub has a personal tap mounted on the wall above it. You pour your own beer. It’s unlimited for the duration of your session. Most people manage 3-5 pints in 90 minutes, which sounds reckless but isn’t — you’re in warm water, breathing hops, and you dehydrate fast. The beer is basically replacing the fluids the spa is pulling out of you.

Worth knowing: the bath water is not the beer you drink. The tub contains beer ingredients (hops, malt, yeast) plus warm water. The drinkable beer is filtered Bernard lager, kept separately and piped to your tap. People sometimes panic that they’re drinking the bath water. They’re not.

The Three Best Beer Spas in Prague

What Actually Happens in 90 Minutes

A typical Bernard Beer Spa visit with the massage upgrade looks like this:

0-5 min. Arrive, check in, change into the provided slippers and robe. Bring a swimsuit or bathe nude — the tubs are in private rooms, it’s your call.

5-25 min. In the tub. The attendant pours in the beer-and-herb mix, starts the jet bubbler, and leaves you alone. Pour your first beer from the wall tap. Talk, don’t talk, nap if you want. Most people do their phone photos in the first five minutes.

25-40 min. Towel off, move to the straw bed in the adjacent room. This is weirder than it sounds — a raised wooden platform covered in fresh hay, warm from below, with blankets. You lie on it and rest. In Czech sauna tradition this is called the “hay sweat.”

40-70 min. Massage. 30 minutes of table massage — standard spa format, body oils, no beer element. You drink water here, not more beer, because drinking during a deep tissue massage is a bad idea.

70-90 min. Change, drink water, maybe another half-beer in the waiting room, leave. You walk out with beer still in your system, hops in your hair, and a level of relaxation that’s unusual after a single spa session.

The Salt Cave (Largest Beer Spa Option)

If you book the Largest Beer Spa (option 2 above), you also get 20 minutes in a salt cave after the beer bath. This is a small room with walls and floor made of Himalayan salt, pink-lit from below, with a gentle saline mist. You sit on a heated lounger and breathe. The claimed benefits are respiratory — the salt ions are supposed to be good for asthma, bronchitis, and general lung function. The actual benefit is that the room is extremely quiet, the light is warm and pink, and you’re forced to relax for 20 minutes with no phone.

What to Wear

The rooms are private (you book the whole room, not a shared one), so it’s your choice. Common setups:

• Swimsuit. Most comfortable for mixed groups.
• Nude. Normal in European spa culture. The staff don’t care.
• Underwear. Fine if that’s what you brought.

Whatever you wear, accept that it’s going to smell like beer for about 24 hours afterwards. Wash your swimsuit immediately. The herb-and-hop smell doesn’t fully come out of hair in one wash either — plan your evening accordingly.

Should You Actually Drink?

Honest answer: moderately. Unlimited beer in a warm bath sounds great, but four pints in 60 minutes in 35°C water will make you light-headed faster than you expect. Pace yourself. The spa staff have seen people pass out from trying to hit the limit of the tap — you don’t have to impress anyone. Two beers spread across the session is plenty.

Water is available at all the spas. Drink it between beers. Keep a glass of water on the edge of the tub. You’ll thank yourself at the end.

A Short History of the Beer Spa

Beer baths are older than people assume. The first documented commercial beer spa opened in 2006 in the Chodovar brewery in western Bohemia, but the practice goes back centuries — monastic brewers in the 9th and 10th centuries would bathe in leftover beer wort as a way of using up the batch before it spoiled. It was never positioned as wellness; it was thrift. The modern spa version rebrands that practice as a treatment.

The Prague beer spas opened from about 2010 onwards. The Bernard brand was the first to scale, opening the Ungelt location in 2013 and the second branch shortly after. The “largest beer spa” venue opened later with a higher-volume model aimed at groups and stag parties. The category now has 8-10 operators across Prague; the three above are the ones worth considering.

The Ingredients — What’s Actually in the Bath

The exact recipe varies by venue but the typical Bernard bath mix, per two-person tub, contains:

• About 15 litres of dark beer base (the unfermented concentrate, not drinkable lager)
• 300g of crushed hops
• 150g of active brewer’s yeast
• 100g of malted barley
• The rest is warm water — roughly 150 litres total

The resulting bath smells strongly of hops — that grassy, almost marijuana-adjacent scent you get in a functioning brewery. Some people love it; a few find it too much. Sit in the steam before you commit to booking if you’re uncertain — there’s usually a small reception area where you can smell the bath before the appointment.

A Word on the “Skin Benefits”

The marketing claims the beer bath is good for your skin: the hops are exfoliating, the yeast feeds skin bacteria, the alcohol (there’s a trace of it in the bath too) sterilises minor infections. Some of this is supported by research on brewer’s yeast masks and beer-based skincare; a lot of it is spa-brochure hype.

The honest way to think about it: the beer bath is a relaxation experience with some real thermal and hydration effects, plus a fun-story element. It’s not a medical treatment and it won’t cure anything. If you’re looking for serious skin therapy, see a dermatologist; if you’re looking for a weird, memorable Prague afternoon, book the spa.

Couples and Groups

Beer spas are mainly sold as couples’ experiences — the rooms typically have two tubs side by side, one bed, one fireplace. They also work fine for friend groups or solo visits, but the pricing structure is geared to pairs.

Solo visits get you the same room but cost only slightly less than the double price. If you’re traveling alone, consider the Largest Beer Spa — its per-person pricing is more forgiving.

Getting There

All three beer spas are in or near Old Town. Ungelt is directly behind Týn Church — literally 2 minutes from the Astronomical Clock. The second Bernard branch is a 5-minute walk northeast. The Largest Beer Spa is about 10 minutes southwest, near Charles Bridge.

Metro: Staroměstská (Line A) is closest. Trams 17 and 18 run nearby. If you’re already staying in Old Town, you can walk to any of them.

When to Book

Bernard Ungelt books out 3-4 days ahead in summer (June-August). The Largest Beer Spa has more capacity and usually has same-day availability. Winter (November-March) is easier — you can often book same-day at any of the three.

Evening slots (after 6pm) are the most popular — most visitors time it as the wind-down before dinner. Daytime slots (11am, 1pm, 3pm) are often available same-day.

Practical Details

Age. 18+ at all three venues. Nobody’s getting into the beer bath under drinking age.

Duration. 60-90 minutes depending on what’s included (massage adds 30 min).

Bring. Swimsuit optional, hair tie if you have long hair, phone if you want photos in the first 5 minutes (the herb-mix-plus-warm-water combination is rough on touchscreens after that).

Cancellation. Usually 24 hours free cancellation; check your booking confirmation.

Tipping. Not expected but appreciated; 10% of the bath price to the attendant is standard if the service was good.

The Ungelt Courtyard — Worth Knowing

The Bernard Ungelt spa is located in a medieval merchant courtyard that’s worth two minutes of attention before or after your visit. Ungelt was the main customs yard of Prague from the 12th century onwards — foreign merchants had to stop here, unload, pay duties, and stay the night under guard. The rectangular courtyard is what remains. Most of the original buildings are gone, but the space still has the quiet, enclosed feel of a 900-year-old transit point.

The courtyard today has a few small cafés and an antique shop. Not much else. The Bernard spa is on the south-east corner, next to the small fountain.

Other Prague Nights Worth Having

The beer spa is basically a wind-down activity. Pair it with something energetic earlier in the day and you’ve got a full Prague itinerary. After a morning Old Town Hall Tower climb and the Klementinum tour, an afternoon beer spa slot fits naturally. If you want to turn it into a full night, a medieval dinner afterwards works — you’re already in a good mood from the spa and the heavy Czech food soaks up whatever beer is still in you.

For a different Prague wellness angle, the Ice Pub is the cold opposite of this — 30 minutes at -7°C, one vodka, done. Some people do both in the same week. For a less niche pairing, a Vltava river cruise at sunset is the obvious post-spa activity if you’re still in the mood for something gentle.
