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.
Finally people are starting to realize that using our heavily (and expensively) treated drinking water to transport our waste to a facility for treatment (where the water is then dumped into our oceans and bays), might not make the most sense after all. Maybe someday all of those wasted nutrients will be recycled on site even in urban environs, but for now we’re happy to see baby steps towards better water efficiency.

Can’t believe my toilet does not have a basin! How much are these selling for?
Is it possible to by the Sink/Toilet in México?
If yes, how much does it cost.
I am in love with this technology but I’m wondering about a few things. How soapy is the water after you flush? It’s grey water that goes into the tank that will later be used to flush the toilet, so it should be soapy, right? Anyway, When cleaning the basin, the detergents you use will also go into the tank right? Does this affect the flushing system and again, how soapy does it look?
I’m from the Philippines, where can i buy this? and how much
Is this available in Brisbane, Australia?
We live in Melbourne and want to buy one too. Roca in Sydney don’t import them we were told. A great shame. Suggest anyone interested calls them as one day they just might get the message that there is demand – though they are about $6k in NZ.
