You have valid concerns and we take extra measures to acommodate steam vapor escape by treating the ceiling and/or adjoining painted surfaces outside the shower with usually an oil based primer and sometimes topcoat of paint . Steam rooms require a few things to be just right and if so you shouldnt have excessive release of vapor. Starting with the proper sized generator for the "adjusted cubic ft" A proper glass install with the acceptable tolerances ( we use sweep and bulb gaskets to compensate for minor inaccuracies and zip our steam showers up and then utilize the transom.) A transom smartly placed in relation to the Fan that also needs to be the proper CFM for the room and other hvac concerns,. Our fans are always on a timer, and preferably jumped on the same circuit as the showers interior light. You want the fan on from the start of the shower and remaining on for 30 +/- mins after you get out. I always suggest opening the transom and swinging the shower door IN to the shower when done. On this steamer ceiling we used the existing bathroom fan and planned ahead and had the painter coat our cedar install with sikens marine grade topcoat. Hope that helps a bit in your effort to rectify your concerns.-best

Well if you havent done constrution yet then ask them about the header boards you will need to install for them to secure the hinges on. Outside of that show them a drawing of what you have or if they are close make them come by and bid it. Outside of that ask them what hardware (hinges, door handle) are standard. Do you need brushed nickle?

Phylhl, your shower is beautiful! Kmcg, very true cost is a factor:) Our contractor hired a sub to install a frameless enclosure & one of the only things we requested in the design was that they cut around our marble chair rail that runs through bath & shower - well, apparently they didnt listen and upon install they not only cut our tile on the wall but they cut a notch in our marble tub surround that also juts into the shower. The notch was not something that was discussed when we discussed the design. Needless to say we are very unhappy with the installation. There are multiple other problems as well - door appears warped, leaking at clip, door leaks(no space for sweep left under door), mitered corner leaks, chip in top of door, VERY sloppy silicone....the list goes on. These are the things we have found & the installer admits there are more problems we havent noticed. Also admits to lack of communication before & during install. We are going to ask that they take down glass, have tile replaced as well as the marble notch be filled in & reinstall new enclosure with cuts around tile & marble. My faith in the company is not that great now but I think the right thing to do is allow them to try & fix it. UGH! To make matters worse our contractor isnt being very supportive - glass people long time family friends. Cant believe our complaints! Good thing we are almost finished & he will not get final payment until we are satisified. Curious to see if we are expecting too much from the installer/owner.

What’s the criteria for deciding to use 1/2” glass vs. 3/8”? Length of unsupported glass, height, . . both? Or the length of the door return assuming the door is mounted on the wall. Something else?
