I'm replacing one double hung window in our bathroom as part of the bathroom remodel. I have about 25 original double hung windows in a home built in 1913 with all natural Douglas fir trim/moldings. So whatever I chose in the bathroom I will need to match up in the rest of the home. I do not want cheap white Vinyl windows. I've done a little bit of research and called Marvin directly to figure out the difference between the three Marvin Windows they make: The Ultimate, The Integrity, and The Infinity. You actually have to talk to three different departments to find out more about each window. What I found out is that the Ultimate and Infinity are very similar looking and would match up nice in an older or even historical home. The Integrity is more modern looking and that's the only big negative for my situation. If I had a newer style home instead of a Victorian Colonial I would opt for a casement window because they seal air tight when closed unlike the double hung, but it would look awful. So the Integrity is out of the equation for me. I found a reputable installer on Angie's List so I agreed to purchase an Infinity window which is 100% fiberglass with the Ever-wood interior option, and rain glass on the bottom sash. I can even stain the interior with a gel type stain to match the existing wood trim. I think it's a great idea to use an all fiberglass window in a bathroom because of moisture and humidity concerns, and to go one step further maybe opt for the triple pane in just the bathroom. Eventually the pine wood will rot away in the bathroom, and condensation will build up on the inside of the glass from showering. Pine is never recommended on exterior trim because it rots out quickly, they recommend Cedar or Douglas fir usually. Recently I used a white PVC vinyl trim that I will never need to paint on the outside made by Aztek from a local lumber yard. I think this would also be a great choice for interior trim inside a bathroom by the way. I've tried the best white exterior paints added the mold inhibitor additives and the paint eventually cracks after a few years. The other option if you want natural wood is to go with a nice hardwood, like oak, cherry, mahogany, or maple and use a clear Benjamin Moore stain, just don't use pine in the bathroom. If I'm happy with the one Infinity in the bathroom I could have all the windows upstairs replaced with Infinity ones. I will opt for the grills only on the windows located on the front of the house. Maybe go with the Marvin Ultimate with stone white Aluminum clad exterior Doug Fir on all the downstairs windows. My house has vinyl siding with storm windows and shutters. The Infinity Installer said they will need to remove the stormers or it will void the Marvin Warranty (which is excellent by the way 10yrs+ I believe) and they will have to use aluminum to wrap the outside trim. There's a little more to replacing the window than I thought. I will update with pictures after the install.

I'm replacing a window in a block wall that has a brick exterior. I will be removing the entire frame of the old window and was planning on using a replacement window without a nailing fin. But after looking at it further, the interior rough opening (leaving existing wood buck in place) is smaller than the exterior brick opening by about 1.5 inches on all sides. This would leave me enough room to use a window with a nailing fin. So my question; should I flash and use a stnd no nailing fin replacement window or go with the window wiht a nailing fin and then flash over the nailing fin?

pella windows will leak, stay away from them, there is a huge class action suit against them at the moment because they are leaking behind the aluminum cladding and rotting the windows marvin make a great product, also take a look at jeld-wen

There is no premium for a "custom" size window in either of those lines. Integrity used to be a stock size program but they do it in any size now. Most windows will have some sort of rot and they can usually be surgically repaired in the process of doing the window replacement. Once the rot is repaired, the new insert can be set and capped/wrapped. If you are messing with EIFs (i.e. full tear out) you need to make sure your installer understands water management and proper flashing.
