Non-stainless steel sink strainer/drain opening options?
We have very hard water in our area and the stainless steel sinks we are replacing are permanently stained as a result. Thus, DH wants me to find porcelain sinks with non-metal sink strainer/drain openings. I don't know what they're called but it's the portion that covers the drain hole at the bottom of your sink and usually includes a lift-out strainer. A quick search of the forums brought up mostly threads about garbage disposals.
What are the non-metal options? Are there porcelain/ceramic drain openings?
Thanks for any advice/help.
