re: Installing right hand drain tub in a location with a left hand drain

I done something similar when I remodeled mine. You can easily break the slab up by using a hammer drill and drilling a bunch of holes where you want to run the new pipe and then using a chisel bit on the hammer drill to break it up. After drilling the holes the chisel bit slides thru the concrete like butter. Just make sure you spray for termites since you will be disturbing the dirt.
