I think we are going to use the white subway tile to keep the budget down as I priced new tiles and it would blow out the budget. Really like the contrast grout idea to add a bit of texture and pattern. My partner is a builder and he loves the reclaimed wood shelf idea as we have a lot of spear old wood left over from the renovation. We have made a dinning table and fire place mantel from it already so it would tie in really well.

Oh so cool you noticed that we're trying to achieve a french country/industrial look or did we write that somewhere? I've attached some other photos of a bedroom and the foyer (of those we've taken so far), but are absolutely open to suggestions on a "beachy" feel as well or instead of. Although because its a beach house we don't want to go over board on expense and hence keeping what we already have, and just adding personality to it, if you get what we mean. Kingsize Black upholstered headboard to come in that bedroom.

You could do a wet room on the south end of the room with the tub and shower combined to conserve space. Window would go above tub, however with privacy in mind it would not be low as you have in your cad drawing. see photo. Vanities would go on the west wall with toilet on the east wall. I am guessing at the dimensions because you mention meters and in the US we use feet, but it sounds like about 9'x15" ? The location of the entry door really impacts the layout of the room, but it looks like it cannot be moved.

The taupe countertops are nice. Have you seen all the new choices of backsplash tiles that are available currently? There are so many beautiful ones, there isn't a need to settle on white subway tiles. Venture out to the big box stores or flooring showrooms and take a look... There are tile caps of all sizes to finish off the ends. A nice one is called a tile liner, and it's about 1/2"-wide. There's also metal strips that can be laid in to finish the tile, it looks very nice. They are called: Schluter Systems 0.375-in W x 98.5-in L Aluminum Commercial/Residential Tile Edge Trim and can be found at Lowe's. They come in different colors.
