Thymes,Oregano,Chives,Sages and Parsley would look great in a sink
You could try Sweet Basil but I always seem to do better with it in my greenhouse. There is a Basil called 'African Blue' which would grow in your sink - it could be placed at the back with other herbs to the front and sides. It would be best to use a free draining compost - maybe John Innes with some multipurpose and horticultural grit added.Others will give you some advice as well I am sure
