Yield of the municipal Ragazerquellen springs supplying Bad Ragaz drinking water: The Ortsgemeinde Bad Ragaz publishes a yield of 170 to 600 litres of drinking water per minute from the Ragazerquellen. This is the municipal supply to the village, not a statement about what reaches a guest room, and no treatment step is published with it.
Regional data is context about the location. It does not establish conditions inside a room.
Safely managed drinking water, Switzerland, 2024: The World Health Organization reports 97 per cent of the population nationally using a safely managed drinking water service. This describes the country, not this property, and says nothing about what reaches a guest room here. It is recorded because it is the background against which a property's own treatment is worth publishing.
Regional data is context about the location. It does not establish conditions inside a room.
Ambient PM2.5 and PM10 near Bad Ragaz, Switzerland, 30 days to 2026-08-17: Modelled ambient air over this location averaged 6.4 micrograms per cubic metre of PM2.5 and 9.3 of PM10 across the 720 hours to 2026-08-17, peaking at 12.2 PM2.5. The World Health Organization annual guideline for PM2.5 is 5. This is the outdoor air over the area, modelled rather than measured on site, and it is not a reading of the air inside any room.

Water Integrity
The resort publishes a source analysis of the thermal water supplied to its baths, giving concentrations in milligrams per litre for fifteen cations and ten anions, with per analyte detection limits reported down to 0.0001 for mercury and 0.001 for cadmium, and cation and anion sums of 104.37 and 287.38 milligrams per litre. The document covers the thermal bathing water rather than the drinking water at a guest room tap, and no laboratory, analyst, method, sampling date or sampling point is named on it.
In their words: “Quecksilber <0.0001”
The resort publishes a hydrological classification of its thermal water as an acratotherm, with mineral content below 1000 milligrams per litre and a temperature above 20 degrees Celsius. The quotation is truncated where the sentence turns to therapeutic claims.
In their words: “The spring is classified as an acratotherm or hot spring (< 1000 mg/l mineral content, temperature > 20°C)...”
The resort names the compositional group its thermal water belongs to, without giving a concentration for any constituent on that page.
In their words: “Based on its composition, the local Bad Ragaz spa water belongs to the main group of chloride-hydrogen carbonate-sulphate waters.”
The resort publishes the delivery route of the analysed spring water to the site, a four kilometre pipeline in use since 1840, and gives the water temperature as 36.5 degrees Celsius. No treatment applied between the spring and the building is published.
In their words: “The thermal water has flowed through a four-kilometre-long pipeline directly to Bad Ragaz since 1840.”
The resort states that thermal water reaches the guest inside the Spa Suites, in a private spa area with a freestanding whirlpool bath and a steam bath.
In their words: “Soak up the healing benefits of pristine thermal water in the seclusion of your own private spa area, where you'll find a freestanding whirlpool bath and a steam bath.”
Zumtobel's undated project release for the Spa Suites states that every bathroom in the Spa Tower has its own supply of the Ragaz thermal water, which is the water the resort's source analysis covers.
In their words: “every bathroom has its own Ragaz thermal water supply, the showers can be turned into a steam bath, and nearly all rooms have their own sauna facilities”

In a January 2012 report on Swiss wellness baths, SRF's consumer programme Kassensturz quoted the person responsible for water quality monitoring at the Tamina Therme, the public thermal bath on the resort campus, describing the bathing water as continuously circulated from a balance tank through a sand filter, disinfected with chlorine and treated with ozone. This describes a campus facility rather than the hotel buildings.
It covers the operator or the group, not this property on its own.
In their words: “«Von dort geht das Wasser über eine Umwälzpumpe durch einen Sandfilter und wird nachher mit Chlor desinfiziert», so Schwengeler weiter.”

The sanitary manufacturer R. Nussbaum publishes an installation report for the haki treatment room at the Tamina Therme on the resort campus, naming the Optipress-Aquaplus and Optiflex-Profix pipework systems, the Optiarmatur and the Easy-Matic actuator unit, and describing a hygiene routine in which the shower line is flushed with 60 degree water.
It covers the operator or the group, not this property on its own.
In their words: “Aus hygienischen Gründen wird die rund 5 m lange Duschleitung zuerst mit 60 °C heissem Wasser gespült.”

Light Rhythm
Zumtobel publishes a project release for the Spa Suites naming the ZBOX lighting management system, four in-room control points at the entrance, desk, bed and bathroom, dimming at night, and the Slotlight, Micros and Panos luminaires in the bathrooms. No colour temperature in kelvin, lux level or flicker figure appears in the release.
In their words: “Four control points are positioned at the entrance, the desk, the bed and in the bathroom to provide the required lighting scenes at the press of a button.”

The resort describes daylight in the Spa Suites in general terms, with no glazing specification, orientation or daylight factor published.
In their words: “Treat yourself to sleek, modern rooms flooded with natural light, accompanied by breathtaking views of the Bündner Herrschaft region.”

Materials and Textiles
Trade press reporting the 2023 refurbishment of the 109 rooms at the Grand Hotel Hof Ragaz records that 186 Airlux mattresses and 436 pillows were installed, naming the mattress brand. No filling material, fibre content, certification or flame retardant treatment is published.
In their words: “186 Airlux-Matratzen und 436 Kissen sorgen für Bequemlichkeit.”

Zumtobel's undated project release for the Spa Suites describes the floor of the rooms as oiled walnut parquet, naming the timber species and the finish type without a product brand.
In their words: “When guests enter their temporary refuge, they step on cool, oiled walnut parquet flooring.”

The published suite equipment list states that the bath amenities are made with thermal water, without naming a producer, an ingredient list or a certification, and describes the room surfaces by material category only.
In their words: “Exclusive thermal water toiletries”
Food and Kitchen
In the resort's own magazine, Culinary Director Sven Wassmer states that none of his ingredients are flown in or driven across Europe, and the article describes regional vegetable growers and a local butcher without naming any of them or giving a share of purchasing.
In their words: “Keines meiner Lebensmittel wird eingeflogen oder quer durch ganz Europa gefahren.”
The resort states that ingredients for its Zollstube restaurant are sourced locally in collaboration with local farmers and producers, without naming a supplier or a verification scheme.
In their words: “High-quality ingredients are sourced locally, and close collaboration with local farmers and producers ensures freshness and quality.”
Biophilic and Healing Design
Zumtobel's undated project release for the Spa Suites gives the height of the Spa Tower lobby, a space guests walk through between the Quellenhof and their rooms, as seven metres, and describes its glazed front. No ceiling height is published for a guest room. A lobby height measures nothing this pathway asks about, so this is recorded as a published detail, not a measurement (Jordan, 18 September 2026).
In their words: “Even a walk from the Quellenhof into the seven-metre high lobby of the Spa Tower, which boasts a glazed front, white leather furniture on white marble floors and very little else, is like a refreshing breeze.”

Fischer Landschaftsarchitekten publish their project page for the resort park, naming themselves as the landscape architect for the client Grand Resort Bad Ragaz, with planning in 2018 to 2019 and 2024 to 2025 and construction in 2019 and 2025, and setting out the shading palette of curved pergolas, shade zones, trees and parasols with its stated purpose in the pool and lounge area. No planting palette or species list is published.
In their words: “Geschwungene Pergolen, Schattenzonen sowie Bäume und Sonnenschirme schaffen im Pool- und Loungebereich eine entspannte, harmonische Atmosphäre.”
The technical reference database BauNetz Wissen publishes the construction of the Tamina Therme on the resort campus, built for Grand Resort Bad Ragaz and completed in 2009 to a design by Smolenicky & Partner, as 115 columns made from 2,200 Swiss firs. This describes the campus thermal bath rather than the hotel buildings.
It covers the operator or the group, not this property on its own.
In their words: “Insgesamt 115 Stützen aus 2.200 Schweizer Tannen bilden die tragende Struktur.”
The published suite equipment list states that the suite has a balcony giving onto the garden or the park, describing outdoor access and outlook without a dimension or a design statement.
In their words: “Spacious balcony overlooking the garden or park”

Disclosures
Compare what each stay offers, how it was checked and what still needs confirming. Assessment labels describe the review, not an overall quality rating.
A low score means a property has not published information. It does not mean the property is unsafe, unhealthy or poorly run.
A score describes proof: what a stay publishes and, on a Human Garage certified stay, what our assessor checked in person. It is not a quality rating of the property. Listings are free, and any commercial relationship is disclosed.
