We had our washer moved upstairs from the basement a couple years ago. The guy we had do the plumbing work didnt install a p-trap initially. The stink came up through the drain. It was horrid. So I feel for you.

Hope the insurance covers it and you are able to get the tub your looking for. I am not sure how disabled you are, but the VA will help pay for accesible bath or shower. I have a hard time lifting my legs high enough to get them over a tub, so they helped replace mine. I had to pay a little out of pocket, but they paid most of it.
