Remodel bathroom with tenant in place

[Brad Sparks]

We're days from closing on an out-of-stateproperty that has a tenant in place. Going in we knew that the bathroom will need to be redone. My questions are:

1-since it's the only bathroom in the house, what should we suggest the tenant do?

2-should we style the bathroom according to our (California) standards or research local standards? 

3-this is our first rental so what am I missing in this situation?

Thanks
