Remodeling Bathroom…what window size?

bk73 | Posted in General Discussion on January 3, 2010 09:37am

I attached a picture of a bathroom I am remodeling in my house. Nothing fancy, but the layout of the bathroom is changing so I’m also going to change the window. In the picture I showed a double casement because I have one around that size. What would be the correct window size for a bathroom like this be? Also, how far off the floor should it be? I was thinking that maybe it shouldn’t extend past the front of the toilet. Thanks. Brad

    Drawing is not great.... So, the window is at the top of the pic with the 4' dimension?

    In the houses we build bathroom windows are always smaller (shorter) than the other windows in the house.

    In any case the window is normally set at the same header height as the rest of the windows in the house so that it will look right from the outside. It's not a set in stone rule though. What is the bathroom ceiling height and the window header height for the rest of the house? The best window for this scenario would have its bottom sill at least 4' off the floor. This would allow a man to use the toilet without having to be proud. :-) In our master toilet room of our own house the sill is 5' off the floor so even my DW who is always worried that "someone might see" can use the room with no window treatments.

    If you really wanted a larger window (taller) you could either apply that spray frosting paint, or apply some of that window film that comes in various patterns that they have at Lowes

    Personally I don’t subscribe to this whole thing about “I have this window sitting around so I’m gonna use it”. Granted it works sometime. One guy here does everything like that. I seriously question if he has ever built any structure that could actually be sold. Donate the excess window to HfH and write off the full cost of the window. Go buy what you need to do the project right. I mean this is a several hundred thousand dollar investment you are dealing with, not a tree fort.

    It might be easier to tell if your picture was a picture.

    Or maybe if your drawing included an actual window.

    On the assumption that the 4' dimension at the top of you graphic is supposed to be some srt of opening........

    I'd vote for something smaller.

    Whatever you want it to be!

    Some windows work great set way up high, just short of the ceiling so the sun angle gets more light farther into the bathroom...other times it's kinda cool having a tall skinny frosted window going from door casing height to the floor.

    Depending on your tastes I don't think there is any wrong answer for a bathroom window on that wall. Helll, I recently saw a complete 3'x4' "shaft" built on the exterior of a house with an overhead glass ceiling that functioned as the bathroom window for a basement bath. The bottom of the shaft was at sitting height--added so much interest to the room that what I originally thought was a mistake turned out to be one of those "wow" features.

    :)

    What size is the double casement you have? (width x height) That would at least be a starting point. The picture is not to good. You might give the measurements of your propose bath. (width of the wall where the window to be located x overall room length)

    There are code considerations for lighting and ventilation.(natural or artificial)

    That is the EXACT bathroom we have.

    We're in an old house, so the original window was a double hung that, if one let the blinds up, would offer a full view to the neighbors of you wiping your rear on the toilet.

    Kind of impractical.

    I replaced the full height double-hung with a (roughly) 2' square awning style casement with frosted glass. It's at the same height as the old one (so, head-height when standing), but no longer offers a breeze/view when sitting on the toilet.

    Being a casement it now offers a better seal in the winter but still lots of morning light. Being frosted and an awning style, we can open it in the summer for letting cross-breeze into the house without exposing too much of ourselves to the neighbors.
