We are remodeling one of the bathrooms. We want to convert a tub to a tub/shower combo. One problem, there is a wood window directly over the tub. We really don't want to remove the window (we are not sure how the front of the house would look without this window. It has two larger casement bedroom windows on each side. Regardless of what I do, I will replace the window with a new vinyl replacement window. I am considering a shower curtain that could be pulled closed to protect the window while showering or, I thought we might simply drywall/tile over the inside opening and leave the window in the exterior of the home?? Any thoughts on what to do? The window could be taken out but, new siding would have to be installed on the exterior and this particular siding 4' x 9' sheets are not readily available.
