Bogn Engiadina

Bogn Engiadina Scuol is the mineral bath of Scuol, the main village of the Lower Engadine in the Swiss canton of Graubünden. It was opened in spring 1993 at a construction cost of some 50 million Swiss francs and combines a bathing landscape, a sauna landscape, a separate Roman-Irish bath and a therapy and wellness centre in one octagonal building glazed by a central roof light. German Wikipedia notes that, contrary to common belief, the house is not a thermal bath under the Swiss definition, which requires water to emerge above 20 °C, but a warm mineral bath: the Scuol springs reach the surface cold at roughly 6 to 8 °C and the water is heated afterwards, with a geothermal plant and heat recovery covering about half of the building's energy demand.

The springs themselves are the reason the village became a spa. Over twenty mineral springs rise along a six-kilometre stretch on both banks of the Inn, owing their existence to the geological window of the Lower Engadine, and their mineral content ranges from 1.1 to 17 grams of dissolved salt per litre. They were first mentioned in writing in 1369, were used in the Middle Ages, and made Scuol, Tarasp and Vulpera internationally known spa resorts around a century ago. The operator states that, apart from the brine and cold-water pools, the bath is filled with pure mineral water from the Vi, Sotsass, Tulai and Chalzina springs.

The bathing area offers six indoor and outdoor baths with massage jets, bubblers, waterfalls and a current channel, together with a brine pool. Published figures give the outdoor panorama pool at about 34 °C over 161.5 m², the exercise pool at about 33 °C over 152.5 m², the two-per-cent brine pool at about 33 °C over 71 m², the whirlpool and the warm-water grotto at about 37 °C, the cold-water grotto at about 16 °C and a textile steam bath at about 46 °C. The Roman-Irish bath is a separate naked area for adults only, runs as a booked ceremony of alternating steam and cold-water baths with massage lasting up to three and a half hours, and is not covered by the ordinary admission price.

The bath is open all year; the bathing landscape runs daily from 08:00 to 21:45, with under-18s admitted from 10:30, and the sauna landscape from 09:00 to 21:45 with a women-only Thursday morning. A major revision and rebuild was carried out in 2026: the house was shut entirely from 13 April to 13 May 2026, the brine bath stayed closed until mid-July 2026, and the sauna landscape is stated to remain closed until early October 2026. The operator's own website could not be reached from two independent networks on 10 September 2026 — TCP 443 and 80 both timed out or refused — so the figures above are taken from archived copies of the operator's German pages captured in May and June 2026, and from German Wikipedia.
