In 2015, Deca launched its first collection in partnership with one of the most prominent Brazilian designers in the international market, Jader Almeida. The partnership has lasted three years and has produced several unique products. In the 2018 line, simple geometry stands out amid a timeless aesthetic designed by Jader in sinks, showers, faucets and accessories. Soft, slightly rounded lines guide the sinks, perfect for projects focusing on design and harmony between shapes. The new line translates the purest design concept into three shower models. In the Round version, the unexpected design creates a curious look, in which the water is distributed along four paths until it reaches the diffuser. The Square and Triangular versions follow the same design as the faucet and mixers created by the designer, bringing an interesting play of shadow and light.

CASACOR has a long history of success as a space for launches and innovation. Deca took advantage of 2018 to experiment with original design pieces signed by two professionals from the cast. At CASACOR São Paulo 2018 , Tenório designed the Deca Cistern , a conceptual space for contemplating and valuing water. One of the spaces that was part of the project was a bathroom for a couple, inspired by nature. The metals and fixtures, including the bathtub, were developed by the architect in conjunction with the brand. Arthur Casas presented the SysHaus modular system at the exhibition . The technology developed by his office made it possible to build a high-standard home in less than a month, with practically zero waste and water consumption. Each part of the project was designed exclusively based on the needs and specifications, in an extremely efficient and functional way. The ceramics and metals were also developed exclusively for the environment and designed by the architect.
