Here's one where we did a free standing tub in the shower enclosure. 

They typically include such things as labor, materials, basic building services, shell features, interior enclosures, fit-out costs, and basic mechanical and electrical systems.

They also have bathroom stuff including frameless enclosures for a good price.There is another place by Levittown who is a little cheaper but the name escapes me at the moment.

I believe it would be up to code to use the old fan enclosure as a box to make the connection to the new fan, or add a box up in the attic that you make the connection in.

For instance, I know that a full gut and remodel including new toilet, new vanity, mirror, sink, glass door enclosure, stone/tile on shower walls, etc will run me $2500 per bathroom.

The only think that might be relevant in my mind is if the field will be generating noise and headaches (dirty streets, rioting fans, etc.) then this can impact your property value and the type of tenants that will agree to live there.On the other hand, if the school's football team is popular, this can be an opportunity to AirBnB the property and have a tailgating setup (there was a company on Shark Tank that did that).So I'm afraid I gave you the typical "it depends" answer but I hope this gave you a perspective of the pros/cons for your situation.

For instance, I know that a full gut and remodel including new toilet, new vanity, mirror, sink, glass door enclosure, stone/tile on shower walls, etc will run me $3000 per bathroom.

It is a good thing they are spending their time doing that while people can steal my tailgate from my driveway and the cops ask me what I want them to do about it!

I have a DNS 323 2 bay enclosure with 2 2TB harddrives for a total of 4TB.

:mrgreen: Let's see, cut a second opening in the base of your shower enclosure large enough to install a closet flange, connect the ball **** to a Y-fitting on the shower head arm... hmmmm, just where to install the TP so it doesn't get soaked????
