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.

softyjain, If the windows need to be replaced I recommend looking at fixed steel to maintain the narrow profile of the windows and small window lites. Using fixed instead of operating will be a cost savings if you don't need to open them. Another option for hanging from the ceiling is a decorative light or chandelier. That way you still have light into your ceiling at night. We offer Renaissance solid bronze windows that don't require any finish or finish maintenance. Architects designers love the rose bronze color, which closely matches copper gutters. http://www.houzz.com/projects/152134/Renaissance-Solid-Bronze-Windows---Doors-by-Progressive-Solutions You may also be interested in this ideabook- http://www.houzz.com/ideabooks/18543834/thumbs/Bronze--Copper---Steel-Window-Ideas

I drew a very crude sketch, definitely not to scale, of how I see your room working. Essentially, you could treat it as two separate seating areas, which makes for easier and more intimate conversation when entertaining a lot of people. Trying to have everyone facing each other in a large room just won't work, and makes for very awkward conversation. I find that at parties and get-togethers, people go off in smaller groups of two to four, then mingle and move around the room to chat with different people. So, to that end, you could establish two conversation areas that will each seat six to eight people. You can also have some of your dining room chairs upholstered and comfortable enough to carry into the entertaining area to create extra seating here. In the far corner by the window, I placed a chair and ottoman, so that is seating for two, and before the get-together, you could place a couple of your dining room chairs over there to create a other small grouping for four. You should still have enough open area in this large space for some people to stand and move around, which a lot of people prefer to do at a party (I know I do!). The bright yellow sofa is a modern take on the old ?English sofa, which in think is the perfect foil to your ultra-modern sectional. The yellow is a bright, cheery - and unexpected - color, but works nicely with white and just says "fun" to me! The small blue tub chair(s) would be placed at an angle facing your white sectional, so you would establish a color,scheme of white, blue and yellow. To this, you could add black, Gray and darker blues through your accessories and artwork. The little blue ceramic drum stool adds a touch of the exotic (and more fun) and is easy to move around as a small side table to set drinks on.

Sorry but I don't understand your pictures. You are talking about 2 bathrooms but we see only one floor plan. Is the 1.52M x 2.24M the 5 x 8 bathroom in your dilemma title. If so, can we see the floor plan of the 5 x 9 bathroom? Is the space with a small rectangle in the middle the extra 5.5 x 4.9 ft space you mentioned in your dilemma? Also 1.52M x 2.24M is in reality 5'0" x 7'4". This is 8 in. less. It can make a big difference on how to place fixtures in a bathroom.
