I have a terrazzo shower pan in an upstairs bathroom -- perhaps 30+ years old -- that is pitted and has one or two cracks under the shower door. The drywall at the base of the wall beside the shower has softened and deteriorated so I suspect there is some degree of leakage. So I will be removing the pan, the tile and the shower door, repairing the wall and replacing everything else.

I need to know the most efficient way to remove the terrazzo shower pan without damaging the integrity of the drain piping. Any help?

I would rent or borrow a rotary hammer. rotary hammer - Google Product Search (http://www.google.com/products?hl=en&q=rotary+hammer&psj=1&wrapid=tlif12855523159372&um=1&ie=UTF-8&ei=xPifTJ7BEcT7lwfF_t3bCg&sa=X&oi=product_result_group&ct=title&resnum=3&ved=0CFkQrQQwAg)
