The focus is on quality

The Rotho company stands for quality at all process levels - starting with the design, to the development, to the production - our quality awareness is rooted and lived every day. We are so convinced of the quality of our products that we give a unique 20-year durability guarantee on almost all of our products.


Our products are all developed in Switzerland and have won some of the most prestigious design awards in the past. In the foreground of each of our developments is the user and his needs. We want to support people in their everyday life in the long term
and offer products that convince through function and quality. For this reason, we are particularly interested in customer-oriented solutions, sensible use of raw materials and timeless design. Because our products should not just stand out for the sake of standing out, but convince through quality and support and delight the user for many years.


Swissness and quality form a unity. That is why Swissness is an attitude for us that all our employees embody. Even if a product is manufactured in a plant outside Switzerland, we do so with the same quality awareness and use the same raw material. Swiss roots and a global perspective shape our culture. This is at the heart of our success at home and abroad.
