The OXO Good Grips 2 in 1 Sink Strainer & Stopper works great for standard sized drains.  Either for kitchens or baths or laundry sinks.  The stopper is easy to twist to open or close and pullsl up with a gentle pull.  The chrome and dark grey rubber are neutral to go with almost any sink decor but especiallly looks nice in stainless steel sinks.
