Our house was built in the 60's. Both upstairs baths have tiny casement windows right in the tiled tub enclosure. While this creates a great tiled shelf area in the shower... it creates huge mold/mildew issues as well. The windows are only about 1' wide, by 3' tall. I should mention that the windows actually do open and were originally intended to vent steam to the outside. Options for remodel? New custom windows? open or not (plans are to install bath ceiling vent/lights). Keep em as casements? What about using glass block for light? I should also mention that yes, we do have accordians for both windows - that are miami-dade approved (for those that might ask..) Anyone dealt with this?
