Michou, it's against code (around here, anyway) to hang a chandelier over a bathtub -- or at least, you have to hang it so high, you might as well not bother. It's a safety issue; It's to prevent you grabbing the electrical fixture if you start to slip getting out of the tub. Check your codes to see if this is true in your area before you do too much shopping.

If you really want that look, you might go for a hanging candle light of some kind. I don't recommend actually lighting the candles when you're in the bath ... hot dripping wax might sort of ruin the ambiance!

Can you hand the chandelier in the center of the room with it lined up to the tub from some important vantage point?

Very nice inspiration pictures. I like how the shower is outside the stall confines;)

A wall light I found on ebay that I bought but haven't recieved yet is a Norwell scone. They are chromed brass and safe for damp locations I am told. They have a web site. I got the Emily, which may be too old fashioned for your plan.

Chibimini, thanks for the tip about chandeliers over tubs. i have no idea if it is against code where I am. i will have to check. i guess i can always hang it a little out in front of the tub and a little higher too.

Enduring, thanks for the the link to Norwell lighting. they look like really high quality fixtures. there are a couple of styles of wall sconces that i think might work. thank you!
