I have a small 4 by 2 feet powder room that I would like to renovate. It is in the basement and has a bulkhead running lengthwise on the ceiling. Part of the ductwork is exposed and sticks out of the bulkhead. I plan on putting in a pedestal sink to make it feel more spacious. I also wanted to tile the whole wall behind the sink but with the bulkhead there I'm not sure how good that will look. I would appreciate any ideas on how to design around these awkward elements. Thanks!
