Not really a designs question; As we start to head toward summer in CA I'm trying to decide on what type of kitchen sink bowl to use? We picked a composite granite sink after reading an article on Houzz and now we want to use a washing bowl as its a must to conserve water during the hotter summer months. The generic plastic bowls get grimy & ugly as they wear and since we're always trying to minimize landfill waste I'm wanting to invest for the long term, any suggestions?
