The 100m euro (£89.3m, US$130.8m) refurbishment at the Grand Resort Bad Ragaz in eastern Switzerland will be completed in June with the launch of a thermal hot spring complex.
The new Tamina Therme thermal spring building covers 78,576 sq ft (7,300sq m) and has a 35°C indoor swimming pool.
A wide range of other facilities are offered at the complex including an indoor sports pool, hot and cold grottos, a whirlpool, hot tubs, steambaths, an outdoor swimming pool, saunas, and relaxation areas.
The water at Tamina Therme is piped from the nearby Tamina Gorge, a naturally occurring thermal spring. One of Europe's first indoor hot baths opened at Bad Ragaz in 1871, on the site of the new contemporary property.
The Grand Resort Bad Ragaz includes two hotels: the Grand Hotel Quellenhof & Spa Suites - which recently had 57 new spa suites added - and the Grand Hotel Hof Ragaz.
There is also a 59,201sq ft (5,500sq m) To B. Wellbeing & Spa facility on site, which also underwent a revamp. Details: resortragaz.ch
