Any Ideas for a vent or window???

[GT1963]

Hi all;

Just cleaning the inside of the bathroom today - and thought we desperately need some type of vent or window for both light and ventilation - short of having the door wide open. When the door is closed it is pitch black - could double as a photo dark room. - there is a light but who wants to turn it on all the time - especially if we are going to be boondocking a lot - must save energy!

Here is a picture of the back - the bathroom area is outlined.

What would you suggest that would look astetically Okay. We are limited to some type of side window/vent as the roof flat is not in the bathroom and I think if we put something half way on the roof it would look silly.

Are there any small sliding windows available that would look the part?? Something similar to that what you get in a boat. what about a unique porthole style window - we have them in our cuddy - they could easily be trimed with Aluminum???

Any suggestions would be welcome....
