Roca is committed to reducing water consumption by developing sustainable products registered with the Water Efficiency Labelling and Standards (WELS).

WELS is Australia’s water efficiency labelling scheme. Labels show a star rating and also a water consumption or water flow figure. The less water used, the higher the star rating. Tapware, showerheads and toilets all have different maximum ratings. Tapware can be a maximum of 6-stars, toilets can be a maximum of 5-stars and showerheads can be a maximum of 3-stars.
