First I would like to say hello to everyone since Iím new to the forum . I had just purchased a home and Iím doing a remodeling job on the bathroom. It had plaster walls that were 1" thick and walls didnít have those slats of wood but it had a material like drywall and mesh together. Anyway I removed the walls and floor "Hardwood" and decided to keep the ceiling because there was nothing wrong with it. When I removed the floor and toilet ect there was no flange on the cast iron piping so now Iím stuck on what to do. I have researched and found that you could use a closet flange but is this the correct way? Also I was going to tile the floor and wanted to get the sub floor and durock at the same height as the old hardwood floor which was 3/4" thick which is no problem I was going to use a 1/2' plywood with a 1/4" durock material but my cast iron pipe would still be higher than the 3/4". even when I lay the tile down I still think it would be higher than the tile. Anyway would it be my best interest to replace the stink pipe with plastic? if so then how. The house is only one floor and everything is very accessible right now. I will take some pictures later to show. Thanks!
