The idea of redesigning bath bottles originated from the observation of a daily need: the use of shampoo, shower gel, and conditioner is frequent, but often accompanied by practical inconveniences. Among these are the difficult opening of the cap, the product that needlessly accumulates at the bottom, and the poor ergonomics of the container, which tends to be slippery and difficult to handle in the shower. We focused on these items precisely because, despite being present in every home, they have rarely been the subject of a real rethinking in terms of functionality. The surveys we conducted confirmed that these problems are widely shared, highlighting the need for a practical, effective solution focused on improving the user experience.
