nah you can do it... but smarter to budget a month without the bathroom.once you start the demo you will keep going until your down to studs and joists.do everything new, you wont regret it.the chamber pot system worked before it can work again.

They will almost all do free demos for you and you can weigh the utility for yourself. 

Not only do you NOT absorb the demo cost.

Good to know if you decide to do any demo.

This should be ongoing activity on your part.For this deal, another approach to consider is get worst case numbers (demo & replace) from contractors and use them for negotiations.  

Our plan is to live in our Rv while we demo and rehab.

I haven't had to pay demo or tile installers or painters or small electrical jobs up front in years.  

Clearly the intent of the ad or this thread is not recycle value, but have any of you ever bought/sold materials from a demo?

DAY 1 OF REHAB: Demo DayImages attached below. 

In this township you can't pull any permits unless has and electric are on.Had to talk to village inspectors get the okay to start demo/ roughs without Permit. no dumpster allowed on site yet but we can proceed with demoing and getting rough a ready.
