My husband had a few contractors come by and all told him to make our glass shower screens go all way to ceiling. The only opening for ventilation would be above the shower door. I prefer the glass having a gap all the way across because more ventilation and think it looks better. The ceilings in the bathroom are 8’. The shower is about 33” by 59” with two of the sides being glass. The shower head is in the ceiling. we have a shower curb. Attached a photo of shower with similar design as well as a sketch of our bathroom. How high should we make the glass screens?
