I painted the walls a soft chalky green (which really doesn't show up well in the photos ... the photo of the shower curtain has probably the best representation. The color is Harbour Town by Benjamin Moore). On the long wall I painted blocks of color and hung black and white prints of photos I've taken on our many family vacations. I let the kids list their most memorable places and use their lists in choosing photos. A nice way to make the space personal! I can always change out the photos whenever it needs refreshing.
I painted the ugly, old orangish oak and plywood cabinets a semi-gloss black and added chrome hardware. Ahhhh ... they look so much better, and set off the white marble vanity, which isn't going anywhere.
I swapped out the old tropical shower curtain and rings for a sleek black and chrome number. I also hung it about 8" higher up the wall which added more drama than I expected.
I, yes, I myself, personally and without assitance, took down the old brass "hollywood" globe vanity lights and wired up these new chrome and glass beauties. And I even did it right the first time! Was a leap of faith to flip that light switch on for the first time, that's for sure.
What's left is the floor (half carpet - what was the builder thinking??? - and half old vinyl), mainly, and a low flush toilet. I am toying with tearing down the tiles in the shower and installing new ones. I am a bit suspicious that there is an insufficient moisture barrier behind those tiles, and better to take them down and find out than to deal with a mold issue down the road. Or, maybe this is just another excuse ...
