I also have a window like that in our shower - it may, but doesn't normally get wet from the shower. I have put in a thin venetian blind in white (made from plastic) very cheap, under $5. I am in process of making an puffy austrian blind to hang above the window, for a bit of colour I am making it from a shower curtain). It will be there for looks, I may never pull it down. The venetian gives privacy and blocks the light a certain amount.

3. Romans. Moving onto the Roman Blind options, I think it important to note that the Romans you have in the other room look to be more ‘Casual Romans.' These are not lined, rather they are self-backed. There is nothing wrong with Casual Roman Blinds but you would be somewhat limited over the choice of fabrics in Australia, Here casual Roman Blinds are limited to plain fabrics such as the ones in your daughter’s bedroom. They are, however, a much more affordable option, though be it at the expense, perhaps, of your ability to be creative and make a design statement in the play room/tv room. Casual Romans require and utilise a pre-stiffened fabric or you will end up with you blinds coming to resemble ‘London blinds’ due to shape distortion and sagging. .. Not a good thing. (and an insult to beautifully made London Blinds) The other type of Roman Blind common in Australia are called ‘Traditional Soft-Roman’ blinds.’ These are lined with pre-stiffened Roman Lining which provides shape stability over time, and offers far superior insulating qualities over Casual Roman blinds because of the lining. They are more expensive not only because of the lining and the labour involved in their manufacture, but because they offer a far greater choice when it comes to fabrics; fabrics which could vary greatly in price, depending on the choices you make. If you want to make a design statement with Roman Blinds, then Traditional Soft-Roman Blinds are the way to go. Reading your post, I think it also worth advising that that you should not be afraid of departing from Romans. We have implemented many solutions with Romans and traditional drapery (eg; curtains and/or sheers) within the same room and even mixing them for the same window. Here are some examples I have found from other professionals on Houzz: Examples of mixing and matching of window treatments within the same room As jenpotts pointed out, you are lucky in that you have the space above the architraves. Mounting the Romans high, they will stack back above the height of the French doors. - So no ducking or blinds catching on the doors if fully retracted (stacked back/up) - It’s hard to tell from the image whether the doors open inward or outward. The bolt would indicate to me that they most likely open outward which is also an advantage. With an all-Roman solution you have several options that could be considered. Option 1 - Roman on the right-hand window and two additional Romans split at the centre of the doors. Option 2 - Roman on the right hand window and 3x Romans, one on each side window of the French doors, and a single Roman that would cover actual doors. An example of where individual (Casual) Roman blinds are utilised for each window panel of the multiple French Doors. I would not advise 4x Romans (one for each door panel and the two adjacent panels), primarily because you have stated the doors aren’t used often and in order to keep costs down, but what I would suggest with all options, is the addition of a single pelmet across all the windows. This would tie them all together off nicely and really add to the presentation of the window treatments collectively. It would also ‘level out' the appearance of the windows. The one on the right looks a little out of place extending up above the height of the French doors drawing the eye and detracting from the overall look of the windows 'collectively.' - A pelmet would level this out, but the downside is that the stack-back on the ‘high’ right-hand window will cause you to lose the upper most portion of that window, with the viewing area reduced to the height of the windows in the French doors and their two adjacent window panels. Here is an example of an extended pelmet that ties the individual blind treatments together. Also notice the addition of the sheer/organza on the right hand side, once again demonstrating that mixing and matching window treatments between window and within the same window treatment is fine. With regards to pelmets. I would suggest a pelmet with a deep fascia… around 25cm. You want the pelmet fascia deep but not too deep so as to overpower the overall look of the window treatments (as a whole). Your pelmet can be padded and lined and I would suggest a coordinated fabric rather than the same fabric you use for the blinds. It’s a real opportunity to make a make a design statement, subtle or otherwise, and will do a lot for the overall projection of the look you want for this room. Ensure you go for a good quality Traditional Soft Roman Blinds. Good quality Roman blinds use pre-stiffened lining rather than normal curtain lining (which is not pre-stiffened and 1/3 of the price). Pre-Stiffened lining is important if you want to maintain the shape of the Romans over time, without them sagging on you. They will also provide far better insulating qualities than cheap Romans made with regular curtain lining. Going 'chain operated' for all the blinds is not an insignificant additional cost given the number of blinds you may elect to purchase, but definitely a decision you would not regret, going forward. This room has potential. Take your time with it, do it justice, even if it means deferring your decision till you can fund it (if that becomes an issue). ... You will have live whatever you purchase for quite some time so it is advisable to take your time making your decision(s) so that your window treatments will be a source of pleasure rather than a source of regret..

Yes, bigreader. My study adjoins the living room but is set much further forward. I wanted to use Roman Blinds in there. On the other side of the living room is the front entry (no windows - just front door) and a wide bifold door between the kitchen/meals area and terrace, then the pantry and laundry which I have wide horizontal windows as well but 600mm high, and I was planning a simple blockout roller blind for each of those windows. The bifold has a special pleated blind that fits into each section and I can't find any other window treatment for bifolds other than drapes, verticals, panels, or shutters that get in the way when the doors are opened. I think it would be quite a challenge to keep them consistent across the front, although I agree it does look better. Here is the plan as it currently stands (a few tiny tweaks to be made yet but nothing significant)

Assuming the front balcony is north facing, and the side window is east. I would do shutters on the French doors and the windows that are either side of the doors. Shutters on the other windows as well. My reasoning is, roller blinds will knock back and forth when the windows are open. If you are sleeping with your windows slightly open for ventilation then this can become annoying. Your home lends itself towards a plantation shutter vibe. You can position the shutters for full sun or partial privacy and everywhere in between or completely closed. Roller blinds are restrictive, they are either open or closed. You could always add sheers or full curtains on the side large window if you wish. The balcony shades the front windows. It really depends on your budget.
