BYOB, ‘build your own bath’ is a design system which brings the bathroom experience to outdoors by being light, flexible, organic and modular. It is constructed with cristalplant material by joining tiles. Tiles can be connected to each other in different configurations to create customised designs and spaces according to particular needs. Rivets are used to fix various bathroom accessories such as basin, mirror and shelves. This project was shortlisted among top 30 in the world by Cristalplant.
