I like my first idea best as far as use of space. I know people say not to put toilets on an outside wall. We had one in our last house in Iowa, but we had 2X6 construction. I don't know how high your window is, but I'm guessing the toilet would fit under there. The shower would be 5 feet long or shorter if you want a wider space to get to the toilet. (kind of tight the way I have drawn). You could do a 5 and half foot long shower and do an angled door at the left end to allow room between the shower and toilet. The vanity would be about 7 feet long, unless you do a 60 inch vanity with a linen cabinet at the door. I would reverse entry door swing if you do that.. The second top right could work and you would still have a small closet. The bottom left plan would require waterproofing your front window. Hopefully someone will give you other ideas. The bottom right plan is bigger, but no closet. Each square equals 1 foot.

Yes, I think pink is a beautiful color for a master bedroom! The trick is picking the right pink and then balancing it with other elements that are not overly feminine. I love pink and brown together, or black. When choosing a grownup ink go to the brown section in your color deck. As you move up to the lighter colors you will see what I refer to as dirty pinks. These are softer, more pleasing pinks that men can love.

I am also always drawn to this inspiration pic of jute/sisal look with light gray walls too, but my husband likes gray as he thinks it won’t show as much dirt and wear....

Pictures would help Is the cream around the fireplace the same as the cream moldings and built ins? A blue gray is going to make the cream even more yellow, but a green gray may work. It will really depend on the blues and creams that are already in the room.
