What about putting down a plastic water barrier under the house?  

It's not brain surgery!

But the bar may be closing because the owner needs extensive surgery.

The stainless face is what your tenants will like, but the stainless tub will last a lot longer with much less problems than the plastic tub alternatives.For flips under 500k, I use fridgidaire gallery (with plastic tub) as they look like a much more expensive dishwasher than they are.

@Steve BabiakBelieve one of the manufacturer recommendations is to store in an approved container outside and re-fill the units outside and to also use a carbon monoxide detector:"NEVER fill heater fuel tank in living space; fill tank outdoors""NEVER store or transport kerosene in other than a metal or plastic container that is (1)acceptable for kerosene, (2) non-red in color, and (3) clearly marked “Kerosene”.

This is a plastic tub, the surround is much worse than the tub.  

A couple of 4' shop-lights, or one of those strings of sockets with plastic cages around each socket, work fine. 

As the wreck had just occurred at this point i was laid up with severe back and neck injuries requiring 324k in surgeries that I can't pay for and the at fault driver was not covered for.

Next if you do it yourself you will probably use 3" or 4" plastic pipe, abs, or pvc.

I will give a call to the company who did the original surgery tomorrow to ask for the price.
