Thanks for all the replies! This is our first house, not our "forever" house. We are planning to finish the bath update so we can put our house on the market within the next 8-10 months. Then hopefully we'll be in our "forever" (or at least for a long time) house. :) The tub in the master is somekind of old, original cast iron tub. So I know it will be a pain in the butt for our GC to remove! I'm not much of a bath person except for occasionally, but my hubby likes to take them a little more than occasionally. Really this update is to make our home more attractive to potential buyers and hopefully secure us a fast sale. The master is one of the only things we haven't updated in our home, and we're not planning on spending a fortune. What I DON'T want to do is spend this amt of money period, and then wish I had done the tub. It's in really good condition, but it's so narrow and shallow. I wanted to potentially put in a deeper, wider one, but the walls are an issue. The non-plumbing side is my husband's closet, which is the same size as mine (not very big, but a "walk in," which is the plumbing side.) Moving a wall is an expense I'm not willing to undertake, so that's why I was wondering if we could hack into the wall just a bit where the tub is against my husband's closet. I havent talked about this with my GC yet. I'll do that this week. But y'all have seen that done?? Removing the tub and taking the time/money/effort to create a big walk-in shower is not what I wanted to do. We do have another tub in the hall bath, but not having a tub in the master might make someone not want our house. It's all about resale at this point! At the lowest remodel cost. :)

I don't know about discount (unless you're willing to shop at Habitat Restore type shops or an architectural salvage place), but I do recommend trying out any tub before buying. It's not weird. :) Drag at least one of those boys to the showroom and make him climb on in. For something as hard to replace as a tub, you need to make sure it's right.

This long and narrow bathroom reminds me of the one I grew up with in Brooklyn. It had the same problems you are facing. I highly doubt there is a radiator in this bathroom. The OP can comment if it exists or not. The large diameter steam pipe in the corner is a typical set up for bathrooms in old buildings. There is probably one thermostat controlling the heat for the entire building. The apartment above does not get to set its own temperature. How warm you apartment is in the winter is determined by what floor you live on. I agree if this is the only bathroom then it should to have a tub. I am not sure if re-configuring the tub is going to lower the resale value on a $1M+ coop in NYC. Putting up the wall between the tub and the sink makes the shower more functional. But it will make the bathroom look smaller and block some of the light from the window. I still think if you are going to move the tub the something like this one at Home Depot could work. It is 6 inches shorter than a normal tub. You will need 54 inches from stud to stud which may be possible once the plaster and lathe are removed from the walls. You could install the tub 8-10 inches away from the window wall. A shelf could be built between the tub and the wall and covered with tile. That becomes a place to hold your shampoo bottles and soap dish. Most of the steam pipe would still be exposed and will keep the bathroom warm even with the shower curtain closed. The shower head and controls stay on the same wall. This will open the space to put in a 36 - 48 in vanity with a granite counter top and a wider medicine cabinets and better lighting. That will give you ample storage space. Something that was not an issue when this bathroom was laid out 100 years ago. Have you asked any of your neighbors if they have remodeled their bathrooms? It would be helpful to get ideas and see how they dealt with these challenges.

I guess I had just been looking at Lowe's and HD to see that a porcelain tub is $255 and acrylic is $250. I figured that was pretty darn cheap and don't see a reason to not go that route. I'll have to look into cast vs regular steel to see what the price difference is. If it's big I'm not sure that I'm willing to spend a big chunk but I'll have to discuss it with my wife.
