You can put the TV over the fireplace, not the best situation but the way the room lays out it is the only logical place to put it. If you could you should add one additional layer on your mantel that could extend it out another 4" to deflect the radiant coming from the fireplace. I would also mount it on a slimline mounting bracket and have the bottom of the TV no further than 4" above the mantle. Ideally you want the TV to be in as straight a line as possible with your eyes. You don't want to look up too high at the TV, it's like being at a sports bar. Also if you can snake up the power and the HDMI from the cable there is a box they make that has both in one so it makes for a very clean installation.

Excuse my duh-ness but i'm having difficulty trying to follow whats going on here. Are these two photos an exact replica of your house and pool ? If not a hasty sketch with dimensions could help a lot. By kitchen wall do you mean the wall behind the bar ? And where is the pool wall ? Are you considering the covered area as being "inside" ? Sorry for all those questions lol Sometimes when you have a design problem you need to turn it inside out or on it's head. If you can't beat it maybe embrace it by making a feature of it : i.e. contrast by having the lightest colored pool surround and a great blue or tile inside and under the overhang, something that will echo the water color ? If you have a great covered area as in photo you'll most likely be spending a lot of time there and it could be soothing to be able to sometimes retire into a darker inside. In my book, 10M isn't small and also contrasting two floor colors doesn't necessarily make a space seem smaller and confined and may in fact even open it up. Could it be that you've thought yourself into a box here ? Sometimes one needs to give it all a good shake up and see how it resettles.

I would look at this room from 2 angles, in this order: convenience (as you have young kids and need everyone to be able to fully use it) and aesthetics. Equipment and accessories: #1 - first look at what is necessary to have in this bathroom: a place where to keep soap, toothbrushes, toothpaste -- all within easy reach for all users (including not-tall-enough kids) #2 - a cosmetic mirror ? #3 - a towel rail #4 - a small cabinet for storage Ideally, #1 should be stored directly on the sink, as it's lower, within easy reach for the kids (see below photo from one of our baths): You can do this also witha smaller sink, like the one we use in the half-bath: If you'd like to keep the one you have (which is really nice), you'll have then to use a shelf (as also suggested by someone else above), and I'd propose one of white porcelain and not one of glass, as it's a lot less reliable with children around. Below, an example of what I mean. The shelf should be installed as low as possible to be reachable by the kids, but also the mirror should be much lower, so that they can use it (much more interesting for them) without having it too low so the adults can't see themselves anymore. For #2 look on the left of the mirror in this photo (if you need it): A towel rail (#3) is absolutely necessary and make sure it's one where you can stretch the towel for faster drying (like the one in the 2nd photo). The cabinet storage (#4) could be placed on the wall from the right of the mirror, as you can see we have in our half-bath (also 2nd photo): Aesthetics: I agree that blinds on the window make no sense, light should be let to flow in as it's much needed in a bathroom. If you don't have time or disposition to paint the walls (and maybe they should remain white anyway, or a light color, because this is a small space), you might use decorations from your DYI center and stick them on the walls (see an example below from my daughter's bedroom, but there are other smaller ones for any kind of space): This way, the room becomes more attractive, more welcoming and more colorful (with very low cost). I hope this helps :-)

I would wait for the rug, until you have the shutters up and your furniture placed..it may take on a character of its own and you'll want to compliment. My first thought though was to coordinate with your kitchen and incorporate some black, with a black/beige stripped rug, which would be fun with the wallpaper and perhaps paint your chairs black, add the shutters and you could paint the window trim black and add a large black chandelier.
