I like this tile as well. Very sleek and mod looking. I would consider running it vertically instead of the picture horizontal pattern. It might give the illusion of more height in the shower surround. The color is great. If you are worried about it being "too much," you could always see if they have the same tile in a different shade and mix the two or doing one wall in a contrasting (lighter) color. I personally like it as long as you have good lighting.

Agreed. and since windows make an essential and large part of a space, Curtains/ blinds become an important design element.

You've got a great space here, and there's so much you can do with it! Do you know what style you're looking to achieve? If you've already got a red and white colour scheme going in your kitchen, you can always opt for this in the living room. Sometimes grey can make the room look a little dark, so it's always worth investing in a white base, and build from there. Maybe change the colour of the curtains to something a little lighter and richer?

Change the pipes which material won't get rusty and corrosion, plastic or PVC is suitable. I think concealed rain shower system is more perfect for your bathroom. Check the link and choose the ideal set: http://www.homary.com/shower-faucets-shower-systems_c157
