There is a supplier of pressed tin advertising in professionals on this site, several pics of bathrooms done in pressed tin. May find some answers there.

Has the plumber advised that it all needs to come out? Or do you want to start afresh? If you want a mid-century look go for light timber and white vanity. Stay away from the 'bowl on the vanity' look and go for a recessed sink. I'd also think about doing something gorgeous (but minimal and modern) with tiles and lights. See the pix below the brass mid-century wall scones give a great effect as do the herringbone tiles not eh walls and black honeycomb tiles on the floor. The key is to keep the palette monochrome (white, grey, black) and add some decorative features. If you want to save $$ (which I always recommend to save on the structural stuff so you have some extra for the fun things) is to keep the plumbing in the current position (unless that is really unworkable).

Thanks, yes we have and found great tiles but are just concerned it will look " messy" !!

MB Design & Drafting, I have to contradict your comment about having only 1 floor waste, we have a large double shower with only 1 floor waste, ours is in the centre of our double shower, our tiles are black and by the time we get out of the shower the water on our shower floor is gone, I always clean the tiles and glass before leaving the shower, I leave the fan on while we dry and by the time we are dried our shower floor is almost dry, we have no trouble at all with only 1 floor waste.. Barbara, we have the same problem, which is not a problem at all, my husband likes his shower much hotter than me but we have our showers turned on to suit each other, we have a small seat at each end to sit on while we wash our hair and feet and each others backs.
