Fixed panel, in my opinion. That's what you'd likely brace your hand on while getting in and out. No need to make it risky by adding moving panels.

Good luck wincymeow. I have a similar dilemma and it is not an easy one to solve without taking away from the "grand" look of a walk in shower. I am considering the extreme option of just removing the window and having tiles along that wall. The only other alternative I can see for you is to settle for the telephone box analogy (it did make me smile when you said that because I can see you think similarly to me in what you want to achieve) or to pay the expense of putting in a different type of window that sits high enough or narrow enough to not receive water splashes from the shower or to go with the option oklouise has suggested. I really hope it works out for you and you manage to achieve the dream ensuite you are hoping for.....( for my own sake, I almost feel like the more mental energy i put into the bathroom, the greater my expectation on its outcome and what i am hoping for, which is definitely not a good thing). Its a pity that you can't move any of the plumbing. I think if you are unable to make any changes to the window, then oklouise first suggestion is a good one - changing the orientation of the shower. (The only real negative with the layout that you have to stay with is that the door opening is in front of the toilet so it is the first thing you see, but I guess depending on whether you make the vanity area the feature or the tiles above the shower the feature, you can draw the eyes away from the toilet based on what you do. I think the changed orientation of the shower is a good compromise and depending on what vanity and feature tiles you use, the bathroom should look really nice because even your mirror will reflect the window and whatever is outside.

Yes, I would go to the website for "Steel Shower Screens Australia" and complete a quote request http://www.steelshowerscreens.com.au/ They do some beautiful shower screens with a fine steel frame, however they are not cheap. Best of luck Dr Retro of Dr Retro House Calls

your dilemma is not quite clear...is this a building with attached buildings on both sides without any option for extra windows...what are the walls and floors made out of and what is the internal size of the kitchen, downstairs bathroom, sunroom and the entry foyer? is it possible to add another roof window above the bathroom to improve ventilation?
