I just bought a house that had a very old toilet in the upstairs bathroom. During the sale, the owners informed me that the upstairs toilet was leaking so the first thing I did was have a plumber come over to install a new toilet the week after closing. When the plumber took off the old toilet, he informed me that there was no flange in bathroom floor. Since, at the time, I had planned on retiling the bathroom floor, we decided that he would not install a new flange right then and just install the toilet over the pipe. Long story short, the bathroom renovation has taken some back seats to some other projects and I have not used this toilet because it lacks a flange. Does anyone know if it is safe if we use this toilet occiasonally until we do have a flange installe? Any advice would be greatly appreciated. Thanks!
