Thank you greaper007.
My diaper pail is in the bathroom. Maybe I should leave it in the utility room to avoid the stink.
Window is pretty standard 6'X6' I think.
I think i will have to go the window replacement route afterall! We are not very handy so I will work on getting a few quotes.
Thanks!
Good luck, what type of diaper pail are you using? We had a diaper pail with a sort of rotating handle. You put the diaper in the top and turned the handle, that dropped the diaper into the bag and completely isolated the top from any smell leaking out. I can't seem to find it online but I think it's the diaper champ. It wasn't very expensive and it didn't require special cartridges or bags. The only time it stunk was when you opened the top to take a bag of diapers out. I only did that in the laundry room though so it pretty much isolated the smell.
6'x6' is going to be a pretty expensive window, especially if you want it to open. When you say cat smell, where is it coming from? Do you have carpet in the bathroom, this was really popular around the time of these windows. If so, I'd suggest maybe pulling up the carpet and treating the subfloor with some sort of pet odor neutralizing product. This could be something as simple as vinegar, I believe, or some other commercial product. I think the best thing to do though is paint the subfloor with a product like killz or bin and then reinstall the carpet. A simple job you could do in a weekend.
Then maybe look into a more powerful exhaust fan in the bathroom, that will be much cheaper than a window that size.
