We considered all of your ideas and more, to the point where we had a sure plan, quoted and ready to go - only to be surprised when we actually saw it. That plan was to make the current ensuite the main bathroom and enter off the end of the room, to reconfigure the WIR to a third bedroom and to make Bed 2 the new master with a walk-thru robe to the new ensuite - currently family bathroom. The issue was that despite taking room from the existing wardrobes between the WIR and Bed 2, the area was just too small - so back to the drawing board. What we have decided to do is keep the same floor plan, knowing that if we choose to sell and return the WIR to a third bedroom it will cost approx. $4K - we think this is a great return on investment, but for our needs the WIR is a big benefit. It turns out our draughtsman missed some vital space where our current pantry exists so we have been able to utilise that space and move the pantry. This has allowed us to change the opening to the main bath to be adjacent to the back door/hall area which removes it from the kitchen/dining/lounge. Despite our best efforts we couldn't make room for a separate shower and bath, so we will have a shower over bath (island style) larger vanity (1200mm) and a concealed cistern toilet. Our finishes will do the talking with exposed brodware michaelangelo shower/bath mixers, beautiful marquina carrara and nero mosaic floor tiles and subways together with a statement wallpaper. We will retain the ensuite as is but we will make the shower significantly bigger, add a large vanity and concealed cistern toilet as per main bathroom. Same finishes. The trick in the ensuite is that we will cover the existing windows opposite the existing shower with the vanity and shaving cabinet (they are frosted from the outside) so we can utilise that wall and it makes no difference to the outside of the house - plus they are double glazed and don't open on that wall so it makes no difference to light or function. Here are the floor plans and the before photos , demo has occurred and we'll be framed and lined prior to Christmas, so stay tuned for more updates!

I would say this is to short. Your bath should be 150 mm from the wall + 75mm standard splash you are at 225mm. The water would land on the edge /rim of your bath. But do not fret. You could install free standing a timber shelf. Above bath for soaps etc and then have the spout mounted onto this? Or just get a new spout?

I like the look of it and the ease and space for the shower, but those baths - a right disaster area for cleaning. I know they look good but convenient they are not - I'm still trying to find an alternative for our room, where I want something similar to the arrangement here.

Moving the niche is not an option at this point. But I do have a question about the niche. My tile installer wants me to consider using the gray tile (same as the floor) on the inside edges of the niche. This is because the wall tile is glass and imperfections in the glass (from cutting it) will show if the glass tile is on the inside edge. How do you guys think that would look? I tried to find photos of a niche where the wall and back of the niche were one color, with the sides being a second color and I couldn't find any examples. Has anyone seen that?
