Hi y'all, I've been lurking here while completing my kitchen remodel. I've ended up with a long skinny piece of granite -- just the right size for a bathroom vanity -- and, by a strange coincidence, a powder bathroom that desperately needs a facelift. I'm getting some info from the bathrooms forum but many of my questions are more decor than technical.

"Before" pix:

What I've already decided: white wood open style vanity (RH Chamfered), blue-gray granite countertop, polished nickel wall mount faucet, Rejuvenation lighting fixtures, white halfway up the wall/blue above, some sort of frameless glass shower door, a white framed mirror. I like beachy, cottagey stuff (but don't want to overdo seaside tchotchkes) and dislike anything that says Tuscan villa, which includes all tumbled stone/travertine look material. I love sombreuil mongrel's bathroom. I'm not moving any walls, and have a very small area to work with -- 5' x 6' plus 5' x 3' shower and hallway.

What I haven't decided, and where I'd love some decor suggestions:

--floor (I'm totally at sea here)

--material of white-halfway-up walls (beadboard or subway tile? I'm leaning toward subway tile but I'd like to hear from decor pros)

--glass shower door to be frosted for privacy or not? The shower will be used occasionally by an extremely shy 14 year old boy.

--Cute deco tiles or not? Even though I like simple, plain, and classic white subway tiles, I've been kind of wanting to put some fun deco tiles (in the shower? On the subway tile wall?) here -- I have a secret love for lobsters and crabs. Sources for same? Or would it be too cutesy?

--Any other ideas would be welcome!

Important point to consider: would your suggestions change at all if this was to be the sole bathroom of an 85 year old woman?
