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.

The blue is awesome (grey is too trendy)! The reason it stands out to you is perhaps because it's the only real colour there. Bring in the blue in a window treatment, a small appliance that sits on the counter, a pretty tray or area rug. Also, it is more appealing often if there are more than 2 colours - so right now you have a white and blue colour scheme - bring in red or orange or fushia - something from the other side of the spectrum (like you did with the yellow flowers but in a more permanent way)!

Changing out my pendant lights dramatically changed my kitchen for the better. The slim modern horizontal shapes made the room feel wider and the colour changed the colour of the wood grain finish of the cabinets.

My new kitchen will be light grey cabinets, white and grey stone bench tops. My current dining table is a clear glass top, black leather chairs with chrome legs/framing. I love these gold polished glass pendants for over my island bench but will they look okay with my dining suite or is it too different? I can go for the grey glass lights but they are quite opaque during the day.
