Mobile plug-in bathroom for rapid servicing

This project has been developed as part of our House of the Future program.

This bathroom is a roll in, roll out stainless steel module with a built in bath, shower, toilet and hand basin. It has been built around a 200 litre water storage and recycling unit. This bathroom can be rolled into any serviced space to make it habitable, either as a living, working or retail space. This mobile unit can be connected via flexible hoses and electrical cabling to traditional service outlets or flexible dry-break connection service systems. All the sanitary fittings can be folded away to allow other uses of the surrounding space.

The bathroom systems are conceived to minimise water usage. The profiles of the fittings are designed to reduce water capacity for effective use by up to 50% over traditional fittings. The design does away with water holding space that is non-functional, without sacrificing comfort.

The toilet is a dry toilet, using only 10% of the water required by a traditional toilet. The unit features a non-mechanical system to liquefy solid waste for efficient disposal. Sewage plumbing cross sections can thus also be greatly reduced. The toilet pan and shower-head retract into the bathroom module and the bath folds up into the shower recess.

Grey water from the shower and hand basin is distilled and purified by the mechanical vapour recompression unit. By boiling water in a vacuum, like boiling a cup of tea on the top of Mount Everest, boiling occurs at a lower temperature due to lower atmospheric pressure, requiring much less energy. The water is then sterilised by an ultra violet light source. This water, now potable, is stored in a 200 litre holding tank for reuse in the shower and hand basin and for flushing the toilet.
