I have told clients this over and over. If you have just one bathroom in your house or condo and need to renovate the bathroom, move out! But no one believes me. That 8 weeks that it takes to do the bath with a permit (and yes it takes 8 weeks and YES YOU NEED A PERMIT.) can extend if problems arise.
Need convincing? Read the article, "Two Weeks Without a Toilet" from the NYT here. This lady bathed in a plastic tub. Seriously, people. This is not necessary. That is what hotels and friends are for. Go ahead, overstay your welcome.
Please – for the sake of humanity, share your renovation delays and problems with a 1-bath reno.
PS The picture above is a Toto Promenade. It's my new toilet. That terrible, existing Kohler keeps overflowing. (No it's not me.) So I got the Toto, the brand I typically put in clients' homes.
