Friedrichsbad

The Friedrichsbad in Baden-Baden is a grand 19th-century bathhouse and one of the most beautiful historic thermal baths in Europe. Behind its Renaissance Revival facade in the old spa quarter, you follow a fixed ritual – the Roman-Irish bath – through 17 stations of warm air, steam and thermal pools. On most days it is enjoyed the traditional German way, without swimsuits. For many visitors to the Black Forest, it is the most memorable experience in town.

History: built on Roman foundations

Grand Duke Frederick I of Baden commissioned the bath in 1868, and it was built between 1869 and 1877 on the very hillside where the Romans had their baths. Construction dragged on because of the Franco-Prussian War, funding problems and the discovery of Roman ruins underground. Architect Karl Dernfeld modeled the symmetrical layout on the imperial baths of ancient Rome, crowning the circular pool with a dome about 57 feet (17.5 m) high. Today the bath is owned by the state of Baden-Württemberg and run by Carasana, which also operates the neighboring Caracalla Spa. Since 2021, Baden-Baden has been part of the UNESCO World Heritage site "Great Spa Towns of Europe".

How the Roman-Irish bath works

The ritual combines Roman warm and steam baths with the dry hot-air baths developed by the Irish physician Dr. Barter. Key stations, in order:

• Warm-air room at 54 °C (129 °F) and hot-air room at 68 °C (154 °F)
• An optional soap-and-brush massage (about 10 minutes, €19)
• Two thermal steam baths at 45 °C and 48 °C
• A thermal full bath at 36 °C and a whirlpool at 34 °C
• The domed pool at 28 °C – the highlight for most guests
• A cold plunge at 18 °C, followed by rest in a warm sheet and tea in the reading room

Towels, slippers, shampoo and body lotion are provided, so you don't need to bring anything.

Nudity, swimwear and age rules

On Mondays, Tuesdays, Thursdays, Fridays and Sundays, bathing is traditionally nude and mixed (men and women together). Wednesdays and Saturdays are swimwear days, when a regular swimsuit is required. Children under 14 are not admitted, and teens aged 14–17 must come with an adult. The soap-brush massage is offered only at set times (as of October 2026: Monday 2–4 p.m., Thursday 4–8 p.m., Sunday 2–6 p.m.) and can be booked on the day from 10 a.m. at the front desk.

Tickets and opening hours

The Friedrichsbad is open daily 9 a.m.–10 p.m.; last entry is three hours before closing, so tickets are sold until 7 p.m. No reservation is needed. Admission for the Roman-Irish bath is €39 (as of October 2026), with no time limit; allow about three hours. It is closed on December 24 and 25.

Beneath the square, the Roman Bath Ruins museum shows walls more than 2,000 years old; it opens from mid-March to mid-November, daily 11 a.m.–noon and 3–4 p.m.

How to get to the Friedrichsbad

Baden-Baden is on the Rhine Valley main line with ICE and EC services; from the station, bus 205 runs to the Caracalla Spa, a two-minute walk from the Friedrichsbad. Drivers leave the A5 autobahn at Baden-Baden and follow the blue spa signs to the "Bädergarage" parking garage, where bath guests get a reduced rate. Frankfurt Airport is the main international gateway, and the regional Karlsruhe/Baden-Baden airport is closer.

Is it worth visiting?

Absolutely, if you are comfortable with German bathing culture – or choose a Wednesday or Saturday to keep your swimsuit on. Afterward, walk the Lichtentaler Allee to the Kurhaus and casino.
