Rent a Porta-Potty for a week....You can't walk on it for ATLEAST 24
hours..I'd wait a little longer than 24 hours before installing the
toilet....And who knows what "problems" you might run into when you start
tearing up the floor....Thinking it will be done in ONE day is ridiculous
for a first time DIYer and where are you gonna "GO" even if it does only
take ONE day...Pretty long time to hold it...LOL......
