Römertherme Baden

What to expect

The Römertherme is the year-round thermal bath in the middle of Baden bei Wien, a spa town about 35 km (22 miles) south of Vienna that has been known for its sulphur springs since Roman times. Baden is one of the eleven Great Spa Towns of Europe listed together as a UNESCO World Heritage site, and the town’s World Heritage office maps its 14 springs and historic bathhouses.

The building is a mix of old and new. Between 1997 and 1999 architects Roland Nemetz, Wolfgang Junger and Rupert Weber built the current spa on the site of the old indoor pool, keeping the U-shaped Mineralschwimmschule, a listed swimming school built in 1847/48 to plans by August Sicard von Sicardsburg and Eduard van der Nüll. They roofed over the former open-air pool with a wide glass and steel structure and glazed the west front, so the main hall is bright even in winter.

It is a town bath rather than a resort. There is no hotel attached, the pools are moderate in size, and the clientele is a mix of locals doing lengths, families and day-trippers from Vienna.

The water

Baden’s water is natural sulphur thermal water, and you smell it as soon as you reach the town centre. The World Heritage office says more than 4 million litres of untreated sulphur thermal water flow every day from 14 springs, at 73-94°F23 to 34.5°C, with about 12 mg of sulphide sulphur per litre. Four springs rise at the foot of the Kalvarienberg in the Kurpark, three near Josefsplatz and seven in the former Weikersdorf district. The coldest, the Peregrini spring right by the Römertherme, averages only about 72°F22°C.

That tells you something useful: Baden’s springs are warm, not hot. Pools that feel properly warm are heated above spring temperature. A family guide that described the spa in 2025 lists the water features as:

• Indoor: a whirlpool, an attraction pool, a sports pool and a separate children’s pool.
• Outdoor: the clover-shaped Kleeblattbecken with massage jets, and the Schwefelwandl, a sulphur-water pool for about 30 people that is used through the winter.
• Garden: a herb trail and a barefoot path.

The same source puts the total water area at about 900 m² (9,700 sq ft). The operator’s own pool list and temperatures could not be checked for this guide, because its website was unreachable in October 2026.

Sauna culture

The sauna area has three saunas, three steam baths and a tepidarium, according to the 2025 family guide. In Austria, saunas at thermal baths are almost always textile-free: you wear a swimsuit in the pools and leave it off in the saunas, sitting or lying on a large towel. Expect that here too, but ask at the desk if you want to be sure, as we could not confirm the Römertherme’s current sauna rules.

Getting there

The Römertherme is at Brusattiplatz 4, 2500 Baden, next to the Grüner Markt (the town’s green market) and close to the Casino.

• By car from Vienna: about 34 km (21 miles), roughly 35 minutes, south on the A2 Süd Autobahn and into Baden town centre.
• By public transport: Baden is on the main southern railway line from Vienna, and the Badner Bahn light rail runs from central Vienna to Baden. Both stop within walking distance of the spa.

The Römertherme has its own parking deck. Parking is free for spa visitors: have your exit ticket validated at the main cash desk.

When to go

The Römertherme is a year-round indoor bath, so it works in any weather. Weekends, rainy days and school holidays are busiest. Weekday daytime is the quiet time.

In summer you have a second option in town: the Thermalstrandbad, Baden’s open-air sulphur beach bath from the 1920s, which celebrated its centenary recently. It is a separate venue with separate tickets.

Prices and booking

The most recent dated prices we found come from a family guide, listing day tickets as of May 2025:

• Adults: from €24
• Teens: from €19.90
• Children: from €14.40
• Families: a family discount applies

The same guide gives opening hours as 10 a.m. to 10 p.m. every day, all year. Prices and hours may have changed, and the operator’s website was unreachable when we checked in October 2026. Before a special trip, call the spa on +43 2252 45030 or email roemertherme@baden.at.

The Badener VIP Card, the town’s guest card for overnight visitors, is sold by the Baden tourist office; check whether it includes a spa discount when you book your stay.

Where to stay nearby

There is no hotel at the Römertherme, but Baden has a wide range of hotels, guesthouses and apartments within walking distance, and the tourist office lists private rooms too. Vienna is close enough for a half-day trip.

Nearby stops worth adding

Walk five minutes to the Kurpark, where several of the springs rise at the foot of the Kalvarienberg, and look for the Ursprungsquelle, the town’s original sulphur spring. The Peregrinibad on Marchetstraße, the only bathhouse in Baden that survives in its pre-1800 form, is just next to the spa, with a fountain that runs with Peregrini sulphur water. The Beethoven House, where the composer spent several summers, is also in the centre. For a bigger, more modern thermal spa, Therme Wien in Vienna’s Oberlaa district is about half an hour away.

Safety notes

• Sulphur smell: harmless but strong. Silver jewellery can tarnish in sulphur water, so leave it in your locker.
• Heat: drink water if you combine long soaks with saunas.
• Children: keep small children within reach; the children’s pool is separate from the main pools.
