To apply the wax ring, first, turn the toilet upside down on a soft surface to prevent chipping or scratching of the porcelain. If the gap is too wide, use a flange extender ring to adjust the gap at the bottom of the toilet. This beefier ring will ensure a tight seal, provided you have the right distance between the toilet and floor. However, one improvement you can make is to discard the budget wax ring provided by Kohler and instead buy an extra-thick wax ring, such as one from Fluidmaster or Lasco for about $8. This system has been in place for many, many decades, and although there are now waxless silicone seals available (Sani-Seal is one brand name), a wax ring is still the default method and one that works very well.

Most toilets are installed with a wax ring that fits over the bottom drain opening (the horn) to create a seal between the bottom of the toilet and the drain pipe. Then, put on a pair of gloves and remove your existing toilet before continuing to the next step. Instead, sever the tape with a utility knife, thereby preserving the instructions.įirst, turn off the water supply to your existing toilet (or the main water shutoff valve to the entire house). If you rip off the tape, you risk tearing off the instructions.

Tip: The installation instructions for a Kohler Highline toilet are printed on top of the box, split by the box flaps.
