Lastly, do you tile the tub/shower surround or use a fiberglass insert?

jon is right...the min measurements are for a fireman to be able to enter and exit. when you cut the concrete, you have to use a lentil or a header on top. also, tie the storm drain pipe to the weeping tile around the house. then fill with 3/4" gravel. bolt the well to the house with anchors. fiberglass wells or galvanized are the two options. then needs a cover.i quoted it for my house... it would cost between $1500 and $3500, depending on the style/size, etc..

We use a lot of Marvin Ultrex which is a fiber glass frame guaranteed for life (not vinyl) and much more expensive.  

it has short fiberglass hairs in it and used for back plastering concrete,,,,blocks,walls. 

Add fiberglass insulation to that and you get a sponge holding that condensation.  

The problem is they drywalled the entire area but stupidly never insulated the ceiling and walls.The drywall is in great shape so I would hate  to rip it out and have to redo it only to put fiberglass insulation in.I could try to take it down but salvage the existing drywall and attempt to reinstall it but even if I could locate and take out all of the screws its probably more effort than it's worth.The other option I have is slow rising spray foam.  

The one-piece fiberglass tub and surround in one of our rentals need to be replaced.

At some point down the road, the inline image won't be up on flickr any more, and this whole thread will look a bit more awkward to somebody reading it for the first time.Some related BP links for your reading - you might get more ideas from people with similar issues:http://www.biggerpockets.com/forums/67/topics/78831-bathroom-window-and-tilehttp://www.biggerpockets.com/forums/67/topics/78694-ponding-on-shower-windowsillhttp://www.biggerpockets.com/forums/84/topics/60299-building-code-window-above-a-bathtubhttp://www.biggerpockets.com/forums/84/topics/66611-tub-surroundhttp://www.biggerpockets.com/forums/67/topics/78806-tiles-debonding--replace-all-or-just-somehttp://www.biggerpockets.com/forums/67/topics/79117-cultured-marble-price-questionhttp://www.biggerpockets.com/forums/67/topics/79001-building-a-bulletproof-bathroom-in-a-duplexhttp://www.biggerpockets.com/forums/52/topics/67384-porcelain-tile-or-fiberglass-for-rentalhttp://www.biggerpockets.com/forums/84/topics/51964-window-or-no-window-that-is-the-question

@Drew Dowdell so there are some fiberglass products that are carried by the Home Depot that are similar.
