At the end of the 1980s, the company extended its business to sanitaryware, namely the production of exclusive acrylic bathtub models and shower trays.

In 1998 the successful partnership A.S.D. - KOLLER GmbH was established, which continues to this day. With its headquarters in Austria and branches in the USA, Spain, the United Arab Emirates, the Netherlands, Malta and the Czech Republic, KOLLER, GmbH is regarded as the world's largest producer of hydromassage equipment.

In 2003, as a result of changes in market policies, the decision was made to focus all the efforts and know-how acquired up to that point on the exclusive production of shower trays, single and whirlpool baths, enclosures and columns. Since then, the company has made considerable investments allowing the constant technological modernisation of its manufacturing process, the improvement of the working conditions of its employees and the adoption of technology suitable for the protection of the environment.

In 2007 it reinforces its strategic position in the market by inaugurating the Warehouse/Show-room in Guia-Albufeira, where a modern exhibition is installed.

In 2012 the production area is expanded, and A.S.D. now has about 15,000m² of facilities.

In 2017 the new Commercial Area is inaugurated, with 2500m² of covered area and which is intended exclusively for the storage of finished product.

In 2019 a new innovative project is started, related to the new product Planstone, developed entirely by A.S.D. and which is intended for the production of resin and mineral filled Shower Bases.

Currently with a prominent position in its market sector, A.S.D. bets on its future, with the optimization of its human resources being accompanied by an excellent team of long-standing employees, who have knowledge and practices that allow them to act responsibly, but also very young people with great competence and creativity.
