I would suggest your plumber links the hot and cold fill pipes to the supply UNDER the sink - this gets rid of unsightly pipes and while he's there get him to move the taps to the L side of sink. I would then create a broad drop down counter top to create a place to sort your laundry ready for hanging out to dry or to fold ready for ironing This drop down counter top to be hinged to R side of washing machine and ensuring the taps are not impeded. If you can't do the drop down version then create a free standing top made out of a piece of MDF/laminated board to put over the sink and washing machine for clothes sorting & folding. This free standing top can 'live' at the side of the washing machine when not needed. I would then put shelves above the folded back counter top to store washing powder and sundries. I would store the washing powder etc in colourful or white boxes to keep the place looking tidy and uniform. Handles on the boxes for ease of access. Oh I do love organising - can I pop round and do this for you? Hope all goes well with the changes.

I could see doing something like French doors with opaque glass so the lite could come thru to the rest of the house. Also double French doors would allow you to open the area up completely whilst doing laundry. You could even leave everything where it is (dryer) and build some storage on the left side. I would image the sink would be very useful - I'd be lost without mine in the laundry room.

I recently saw this episode of Ask This Old House where they demonstrated painting tiles - especially as a solution to get one through till an entire redo is possible. http://www.thisoldhouse.com/toh/tv/ask-toh/video/0,,20902001,00.html Looks like you are doing a great job!

If I had a small child, definitely. Plus, I use my bathtub for so much more than baths. It's also great for pet baths and other cleaning duties. I don't have a utility sink in my laundry, so maybe if I had a utility sink, I would not need the bath tub so much.
