BubbleBox is a mobile and autonomous hygiene unit that provides migrants, refugees, and homeless people access to showers and washing machines. Its design is conceived to assist public authorities and NGOs in the management of the current humanitarian crisis, first in the North of Paris then beyond.

Built in a repurposed shipping container, the unit is equipped with 4 to 6 individual showers and manual washing machines. The unit uses solar energy to heat the water and power ventilation, as well as a water filtration system known as “Showerloop”, which recycles up to 90% of the water. These efficient and sustainable technologies allow the BubbleBox to function with or without connection to the water and electricity grids so it can welcome users while mounted on a truck or laid on the ground for long-term needs.

By involving local experts and community members in construction and greywater collection, BubbleBox provides a versatile, durable, and cost-effective strategy to improve individual and public health outcomes.
