Whether you are replacing an old and worn out toilet with the same model or replacing it with an upgraded, you will want to know some things before starting. This will make the installation process a little easier on yourself and perhaps you may not need to call a plumber.

  • Before you buy a toilet and try to install it, you need to know the rough-in measurement. Simply take and measure from the wall to the bolts that hold the toilet down. If you are lucky, more than likely the measurement will be 12 inches, which is pretty much standard, but some times the measurement can be either 10 inches or 14 inches.
  • When removing your old toilet, you may have some trouble trying to loosen the nuts on the holding bolts. If this is the case, you can try using WD-40 to loosen the nuts, but if that does not work you may need to just cut the bolts off.
  • Make sure you buy brass bolts when purchasing your new toilet, they will are not only easier to cut later on when needed, but that also will not rust.
  • If you have an uneven floor in your bathroom and you place a toilet on it without using shims, you run the risk of break the wax ring seal and causing a leak. Once you have placed shims under the toilet, that is if they are needed, you will then want to place caulking around the toilet in order to seal it.
  • If you want to avoid cracking the toilet itself, you will want to tighten the bolts loosely and sit on the toilet in order to seat it to the wax ring. if you simply place the toilet in position and tighten the bolts all the way, you run the risk of cracking the toilet and running the base.
