Brass body plumbing fixtures no plastic or abs.

If it is way out of the norm like a....recycled beer can wall bonded with a recycled plastic polymer (just the craziest thing I could think of right now) then you stand to have quite an expensive hurdle getting it tested and designed to pass scrutiny. 

When you get estimates from folks make sure they say there gonna hang plastic at least.

One thing I've done to keep the walls looking nicer is to put the plastic strips on all the outside corners.  

This isn't brain surgery, but you can't ignore the basics or pretend that they don't apply to you.Good Luck,Mike

Seller has told me directly that he is VERY motivated to sell since having bypass surgery (will take less).

Think about it like this...you could go to university for years to learn complex studies like rocket science, astronomy, quantum physics, engineering, surgery.

A hole in the wall was concealed with that plastic molding that goes up against the wall where it meets the floor.

The next day(yesterday) I had surgery and they put a steel plate in and I am now out of commission for 6-8 weeks including physio.

Since it was clear plastic bag everybody could see what he had.
