Idrosun SA

ABOUT US

With over 40 years of experience, Idrosun SA is today a well-established player in the wellness and building technology sector.
Its story began in 1981 with a family vision: to offer tailored solutions that strike a balance between technical innovation and human care.

Idrosun SA was born from the intuition of Willi Maag, who founded the company with the goal of uniting craftsmanship, technical expertise, and design quality.
Over the years, the company has expanded its fields of operation, integrated advanced technologies, and established itself as a trusted partner for private clients, engineers, architects, designers, and businesses.

Today, the company is led by Simon Maag, who took over from his father and now fully owns the company, continuing its development with a forward-looking approach.

We are mainly active in Ticino, Engadin, the Zurich/Zug region, and Northern Italy, managing bespoke projects in residential, hospitality, and commercial settings. Thanks to our multilingual team, we communicate daily with clients and partners in Italian, German, English, and French, ensuring smooth and professional collaboration across multiple markets.

From the very beginning, our way of working has stood out for its complete and structured method:
every project is followed through all its stages – from the first consultation to the execution and long-term assistance – with consistency and care.

An approach that has shaped the company’s identity and continues to define how we work.
A story that keeps evolving, building new spaces of well-being every day.
