Combat Drought: Sinks & Toilets
California has been surviving the worst drought in recent history, the last one being from 1985-1991. San Francisco’s local government is cracking down on wasteful residential and commercial water usage with a call for a 10% reduction in overall water use and a 25% reduction in outdoor irrigation.
Wrapping up our series of blogs focusing on creating eco-conscious interior design, here are tips and products that will make conserving water simple and beautiful.

So what can we do to help reduce water usage? Today’s edition: Combinations that use sink greywater to flush the toilet!
If you’re short on space or even if you have plenty of room and want to reuse the greywater that goes down the drain every time you wash your hands, sink and toilet combos are an excellent idea.

The Caroma Profile Smart 305 Round Front is a unique design with advanced performance: A high-efficiency dual flush toilet using just 1.28 or .8 gallons (4.8/3 liters) per flush. After flushing, fresh cold water is directed through the faucet for hand washing and drains into the tank to be used for the next flush. 27.75″L x 15″W x 35.875″H with a bowl height of 15″, this water-saver will fit right into any bathroom or half-bath.
In a more daring shape, the W+W from Roca brings elegance and sustainability to the bathroom. This sleek design houses a nifty self-contained greywater system that is capable of reducing water use by up to 25% compared to a standard 1.59 or .79 gallon (6/3-liter) dual-flush toilet. The toilet is just 16.14″L x 20.47″W x 19.69″H and the sink is 11″L x 13.38″W x 19.69″H, beautifying any loft space or small apartment while taking up very little room.
