We spotted this fancy multi-tasking toilet/sink by Roca at the London Design Festival. It’s obviously compact and perfect for any loft space or small apartment, and its sleek design houses a nifty self-contained greywater system that is capable of reducing water use by up to 25% compared to a standard 6/3-litre dual flush toilet. It’s a much trendier and elegant solution to existing sink to toilet greywater systems, and we’re excited that high design has embraced waste-water management.

Combo sink/toilet systems such as this have been prevalent in Japan for years, but Roca’s W + W (washbasin + watercloset) looks much more practical and introduces some fresh features. The system uses Roca’s “water-reuse technology” and also features an automatic cleaning system that avoids flushing bacteria into the unit’s built-in cistern, cutting down on unpleasant odors.

Wonderful! When will this catch on in the US?
