Could you put the laundry behind doors so that you won't see it with the walk through...by the way...I am just over the water in OZ, know what you mean by costs... will get some pics....this would be my option...just going on what you are saying.... The good thing about this is that you can shut the laundry away except for when you are washing...... I would have the washer with the dryer next to it if you can and put a bench over the top of the both of them....for this it is worth getting a front loader if you haven't already got one.. this will avoid the bench on the other side...it can all be contained and done on the one side of the laundry. Don't go for sliding doors ...the glass look great but they will need a bottom track and if they don't have one...they will move a lot....not great for this even though they look great. As for having the bench over the top of the washer and dryer, you can then have overhead shelving, does not need to be cupboards as the bifolds will hide what is in there...double cost other wise. hope this helps...Robyn

Photos would help us a lot but mint and grey usually goes well with charred oak.

I have a similar sized ensuite in my own house and would definitely not put two doors in it. You will probably find that a fixed glass panel to half the width and a glass door the other half would work fine. Alternatively you can get a sliding glass door (again 50/50) if you like the look of them as they do save on space.

I have to ask, do you really need that bath when you have such a tight space? Unless you have tiny children (and remember that's a temporary situation!,) I suggest a larger walk in shower e.g. 1200 x 800 and heated towel rail on the wall nearer the window so its more convenient. Would definitely keep the double vanity for those busy mornings with storage under and you could add mirror fronted cabinet recessed into the wall above the basins to add more storage. Hope that helps!
