Window replacement - Odd style window

[99_xc600]

I'm in the process of replacing the old wood double hung windows in my 100 year old house. For the most part all of the windows are pretty standard except for the window in my 1/2 bath on the 1st floor.

The window is a casement style that opens into the bathroom. The sill is flat on the bottom. So essentially I'm dealing with a deep box to fit the window into. Do I just treat it as a normal replacement window and specify the sill to be flat and then trim out the inside of the window with traditional jam stops?

The bottom of any replacement window is "flat" already. There is a piece called a sill extender that snaps into the lower edge of the window jamb that provides the necessary point for the replacement window to sit on a sloped sill.
With only two pictures, I would say that the way to approach the replacement would be to remove the storm window (the replacement window will have an integral screen) and hopefully the existing jamb will have a sloped sill from the point where the storm was attached outward from the building. Then proceed to install the replacement window by applying what's called a "blind stop" in the existing jamb, where the storm window was mounted, Then install the window followed by an interior stop to trim the window off to the existing jamb. Note that the depth of the replacement window jamb will be about 3-1/4 inches and that the new window will probably end up somewhere in the plane of the existing hinged sash when you're done.

If the existing exterior sill is not sloped, your best bet is to install a sloped sill and adjust the height dimension of the replacement window to make it fit.

Yes, the exterior sill is already pitched like the rest of the windows and the storm is already attached to a blind stop. So it sounds pretty much just like any replacement window with the exception of the sill extension for the bottom of the window.

Thanks for the advice!
