Throughout history, the functional essence of bathrooms has remained unchanged due to their design being shaped by biological parameters. Initially, the function of bathrooms was solely related to hygiene and waste management, resulting in the conception of bathrooms as unhealthy and merely utilitarian spaces. This led to their separation from the rest of the spaces designated for coexistence.
However, the implementation of water supply systems and general drainage networks has vindicated the role of bathrooms in living spaces. They have acquired a primordial role in design proposals for interior design and reflect the user's personality through the combination of colors, coverings, accessories and decorative elements. In the evolution of bathroom design, proposals that stand out for their formal cleanliness, multiple nuances, subtle coexistence of elements, and customization possibilities have emerged. Brands like antoniolupi have developed bathroom furnishings that integrate these proposals and take the limits of design much further by collaborating with renowned architects and designers like Paolo Ulian, Brian Sironi, Luca Galofaro, and Mario Ferrarini, just to mention a few. Continuing with this series of collaborations, Carlo Colombo was in charge of developing Borderline.
