Medicine cabinets have come along way in recent years. The best option is to get a frameless style and integrate it into a wall of mirror. You can mount sconces thru the mirror on either side of the cabinet. If you have walls on either side of the sink, you can put the cabinets to the side, integrated into mirror again. If you have an open wall in your bath, yo can get an extra tall medicine cabinet to hold loads of stuff. There are loads more on houzz photos. Just search medicine cabinet. Sometimes you have to hunt for the cabinet because they are so well integrated. Robern makes some of the best frameless styles, but there are a ton of others on faucetdirect.com. Many even come with integrated lighting for a very modern look.

You are so right white is never out of fashion. I would set your budget and then look at your options. If you plan to stay in the house for many years then spend to the top of your budget (if that is going to give you a life time of pleasure), if you plan on being at the home for only a short time / few years then I would go mid range so it looks lovely, will have good resale value but you can invest your well earned money to go towards something else as well. Obviously Marble / Granite is the top of the range but there are so many cheaper and very attractive options these days that look just as good.

If you can narrow the linen cupboard, then you do do a similar layout to that GB has shown but with a changed door swing, swap the basin and WC, putting the WC on the wall beside the door so the WC is concealed behind the door.

Hi We are torn between a black and a white bathroom vanity. Here are the details of the bathroom: Large marble tiles on floor and up walls. With large round mirror above vanity One feature wall in charcoal hexagons Chrome tapware Concrete basin. We are wondering whether to put the basin on a white concrete top and white vanity front (safe!) OR Black vanity with either white or black top. Love the idea of a black vanity- I think it would really pop with all the grey/white in the tiles/basin etc but would it look odd with a white top (so 3 diff colours grey basin/white top/black vanity front) Better to have a black top? Anyone got an examples to show me? Thanks
