Quality tested

We set the standards

The Wellness-Hotels & Resorts’ cooperation has been the number one choice for wellness hotels since 1997. The quality seal, which depicts the wellness tree, has gained huge trust amongst affluent guests because only hotels fulfilling certain quality standards receive the seal.
We have developed mandatory criteria, which all the hotels must fulfil to be able to receive the desired brand name. The wellness tree guarantees tranquil, natural surroundings, at least a four-star rating, an attractive and well looked after wellness area, competent staff, sustainable environmental management and wellness-vitality cuisine. Our specific wellness criteria sets standards for the entire wellness industry to the extent that the largest German hotel and restaurant association (DEHOGA) and the German International Hotel Association (IHA) have adapted the classification to set the wellness tree standards as an official benchmark for all wellness hotels in Germany.

The wellness tree quality seal

The following criteria are regulary reviewed externally by TÜV Rheinland - an international body for safety and quality certification - in our parner hotels at a maximum of 24 months. The three-day review takes place as a mystery check and includes the reservations, hotel, catering and of course the spa and wellness department including treatments. Wellness hotels displaying the wellness tree quality seal will guarantee:
  • 4 and 5-star rating
  • Outstanding service with a focus on guests’ individual needs
  • Attractive, well cared for and spacious spa and wellness area with pool, saunas, beauty treatment area, sports and relaxation facilities
  • Extensively qualified, friendly staff in all areas of the hotel
  • Wellness-vitality cuisine                                      
  • Attractions and activities
  • Environmentally aware hotel management
  • Contractual obligation by the hotel to carry out continuous quality and quality assurance checks in all areas
  • Non-smoking rooms
