If you do the heating wire you may want to upgrade that section of pipe to plastic piping which won't attract as much cold as metal pipes.

The local inspectors here spot every defect and require them to be fixed (small leak stain on ceiling, tenant-destroyed drawer, plastic accordian door off its hinges, etc.) 

All we have to do is wrap in 4mil plastic and duct tape all seams.

Just last week I had a tenant complain about burnt plastic smell.

I think they were burning something plastic. 

Repiping the house to plastic pipes from the old iron ones?

Try your local fencing supplier they often have guys/subs that will pick up jobs they outsource.We did that with a local supplier here & had a couple of guys put in a complete backyard fence, 4ft high black plastic coated wiring, for $2500 including materials that they picked up & hauled.

Tile is more expensive than the fibre-glass/plastic surround that just glue to drywall, because we use backer board to suds.Now in the past for <C-class rentals we were guilty of just gluing up sheet linoleum as a stall surround & they worked great.

If plastic and needs replacement what are you doing with the show surround and plumbing?
