Replacing an old shower enclosure?

[NIB]

Jeez it's a neo angle.NIB makes short work of that in No time.
Theres a trick to keepin the drywall neat.Take a SR knife an carefully slice the paper of the sheetrock along the outside edge of the tiles.Then U pop of the ouside row af trim tiles an cut the drywall along the tile line with a pigsticker.Thats one of them knife shaped drywall saws.U have to use a hand saw so's not to cut thru any pipes.It keeps it neat.Now u have a dry wall headache to repair.
Can u get underneath to remove the base.If u just undo the top nut on the trap it should come right up.Same thing as with the walls cut the caulk along the base with a knife first..After u take the nails off the lip if there are any.Be shure to change the trap while ur doing this..
Leave it on while ur doing this so no street back gasses(rotten eggs) or other water comes thru it..
When u set the new base.Get some structolight or plaster or a few bags of cement to set the base in it makes it nice an solid.Many of the fibergalss models have a good amount of bounce in em..
