We are building as well, our ensuite is similar size. We are having double tiled shower, double vanity and toilet. We didn't separate toilet as it was a added cost and didn't see the point in the master

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.

I currently have the same problem! I wanted that but the tiler didn't do it. I saw it after the shower was finished tiling (when I got home from work). They told me it was too difficult to cut the porcelain tile in a triangle shape and install. I did some research and I can't find a product that can hold weight, even if it is just to shave my leg! I suppose I should have had a triangle corner with a base (that wasn't floating) but I think it is too late. Hopefully someone can tell both of us a better answer. Just realize this was posted July 2014....... where you able to solve the problem??????

This layout is not what i would ever suggest to a client for starters the MBR and DR are all wrong , who wants to walkthat far with food from the kitchen the DR is completely closed off of the rest of the space just too many things to correct for me.I really dislike homes built to look great from the outside with no proper function on the inside
