hH, can you post a quick plan sketch of the room with dimensions window size, fireplace door etc? thanks

we've had a full height window in a shower overlooking a gorgeous bush view and the only concession to privacy was to install a roller blind that could be used if/when needed (for more discreet visitors and at night looking out felt a little exposed) have the two windows the same height and tiled into the reveals and consider a walk in shower with the shower grate against the outside wall although you should consult a plumber and tiler before committing to any ideas as there will be potential restrictions with drainage ..i would be inclined to have a tall narrow louvre window between the toilet and the post and same height fixed panel in the shower although the best size and shape will be decided by structural decisions and budget but a triangular fixed glass panel above both windows would look spectacular...i've also suggested moving the entry for a more generous shower space with the post enclosed, 1200 wide wall hung vanity for your exciting basin and in wall mirror doored wall cabinet to reflect the view to be seen from the loo

some variations to consider but keep in mind that if you have the bath under the window and the vanity on the side near the door there's only 600mm between the shower and a standard vanity

The doorway that sarah has shown at the entry prior to stairs will be load bearing to support the stairs above where they change direction. But it could just be an entranceway. Okl opt 3 I would prob do a 1200 enclosed shower to get a decent sized towel rail outside shower, with door and short end and shower tap near door. Bath robe hooks on door. Not sure if enough the height for toilet under stair, sadly.
