We didn't have a choice. We were our own labor. Our kids were still under roof. So there was no other bedroom to move to.
We did plan a weekend trip immediately following the floor leveling application - as mentioned, that's kind of toxic.
Our bathroom used to be open to the bedroom (very 60's to do that)... The first step we did was build a wall and door. That allowed us to close off the bathroom from the main bedroom to contain the dust, etc. The bathroom has a fan and a window, also, so those were used extensively. And my husband set the fan to blow IN to the bathroom, creating a negative pressure when the toilet fan was on.
No regrets about how our bathroom came out - it's still gorgeous, 10 years later.
