Cold plunges, thermal baths and 70+ treatment rooms: Therme Singapore breaks ground

Singapore’s wellness landscape is set for a major expansion with the groundbreaking of Therme Singapore, a S$1 billion integrated wellbeing destination slated to open at Marina South in 2030.

Developed by Therme Group, the Vienna-headquartered company behind some of Europe’s largest thermal wellness resorts, the project will span more than 720,000 sq. ft. – equivalent to over nine football fields – making it Asia’s first large-scale urban wellbeing destination.

The seven-storey development will feature more than 20 indoor and outdoor pools and water bodies, alongside over 70 wellness treatment rooms. Visitors can also look forward to over 86,000 sq. ft. of dining and social spaces, many of which will offer views of the waterfront.

What to expect at Therme Singapore

The destination will be organised into three distinct zones: Play, Relax, and Restore.

The Play zone will focus on family-friendly recreation, with children’s pools and 18 water slides. The Relax zone will house thermal pools, therapeutic mineral baths, hydromassage beds and infrared therapy experiences. Meanwhile, the Restore zone will be dedicated to recovery and rejuvenation, featuring saunas, steam rooms, cold plunge pools and massage treatment spaces.

A nearly four-hectare coastal public park will also be created to connect the development with Marina Barrage.

While the scale of the project is significant, Therme Singapore’s arrival also reflects the growing popularity of thermal wellness and hydrotherapy within the broader longevity movement.

Many of the therapies incorporated into the development – including thermal bathing, cold-water immersion, sauna therapy and hydrotherapy – have long been staples at some of the world’s leading medical wellness resorts and longevity retreats.

At destinations such as Grand Resort Bad Ragaz in Switzerland and Lefay Resort & Spa Lago di Garda in Italy, thermal and mineral-rich waters are integrated into programmes designed to support recovery, stress management and healthy ageing. Likewise, wellness group Lanserhof incorporates hydrotherapy, heated pools and sauna facilities as part of its preventive health philosophy.

Closer to home, Japan’s centuries-old onsen culture continues to be regarded as an important pillar of wellbeing. The practice of toji, or hot spring therapy, is based on the belief that regular immersion in mineral-rich waters can support physical recovery, mental wellness and long-term health.

Interest in these modalities is also growing in Singapore. When MORROW Health, the recovery arm of MORROW Medical, fully opens in the third quarter of 2026, the longevity-focused destination will feature an integrated hydrotherapy circuit comprising warm pools (38ºC to 40ºC), hot immersion pools (40ºC to 42ºC) and cold plunges ranging from 6°C to 15°C.

The science surrounding thermal wellness continues to evolve, but studies have linked regular heat exposure and bathing to benefits such as improved circulation, reduced stress, better sleep quality and enhanced recovery.

For many wellness enthusiasts, alternating between hot and cold environments – known in the industry as Contrast Therapy – has become a popular strategy for managing both physical and mental wellbeing.

Founded in Germany, headquartered in Vienna, Austria, and best known for its flagship destination in Bucharest, Therme Group currently operates and develops large-scale wellness resorts across Germany, Romania and other international markets, with projects underway in Europe, US, and Asia.

When Therme Singapore opens in 2030, it will not only add a major new lifestyle attraction to Marina South. It will also bring a wellness practice long associated with European spa towns, Japanese onsens and luxury longevity retreats into the heart of the city.
