We replaced the shower stall with a 2-piece fiberglass unit that doesn't require caulk (using a unit that I salvaged from a rehab of another unit several years ago and had in storage) and replaced the floor with VCT.

hey pocketeers,What do you prefer for your rentals....Tile surround with tub or fiberglass tub and shower surround?

Overall,  the fiberglass tub is in fairly good condition but the stains.  

Figured this out when I moved it away from the gas hot water heater.He also handled eco fiberglass by hand and told us its safe because it's ECO.

Austin is really hot and all my rentals are 1980's built and we blew about afoot of loose fiberglass insulation in the attics to save wear and tear on the ac units as well as keep the tenants bills lower.

I think fiberglass bat is R19 off the top of my head. 

Steel or fiberglass door will be fine. 

same here ($18,000 1500 sq ft) on one of our commercial metal roof bldgs the membrane appeared to be a fiberglass material but it has held up extremely well (4 years).

Fiberglass tub/shower combo with surround?

If you've already tried the first step by observing what happens outside and in during a heavy rain - making sure that water is redirected away from the foundation by making sure that the gutters are working correctly, the downspouts are emptying at least 6' from the foundation, and that the soil is graded away from the foundation - and you're just looking for a quick fix, you might try plastic or fiberglass wall panels.
