Just wanted to thank everyone for their input.
He offered to purchase a new bathtub and install it, which is the route we took.
One question, this new bathtub required a mortar bed be installed. Is there any issue installing this on the 2nd Floor of an older home (Built in 1922)?
He didn't put a mortar bed under the first one, so I'm curious as to what the repurcussions of not installing one are?
