The sink is cast in pewter, and therefore can be polished with fine steel wool for a stainless steel finish, or painted with suitable paints (car paint or acrylics) for a contemporary composite effect.
Measuring 3 1/8 inches by 1 5/8 inches it requires a hole 2 7/8 inch wide by 1 3/8 inch. The sink will fit ELF 2 inch and 3 inch units, though you will require another unit next to it, to allow for the drainer.
Note you will need to order a tap separately.
