I have an Autotrail as well, and my Bathroom window is clear same as yours.We always leave it down as Autotrail fit a clear window in the bathroom (why?), Can I bleach it, paint it or replace it with something more suitable? Any ideas please?
My son bought something similar from Ebay to do a bathroom window which for some reason had clear glass in it. Lasted for 10 years with the shower being used twice a day.I have an Autotrail as well, and my Bathroom window is clear same as yours.
Rather than keeping the blind closed, I went for an alternative approach and 'frosted' the window instead - also gives more light whilst still keeping privacy. Maybe just an option to consider?
(the stuff I used was not wide enough for a one-piece application but still looks good IMO. You can get sheets that would be, but we already had some of this left over)
