fit the need for tile installation

Would Recommend

I'm replaced rolled vinyl with tile, so the toilet flange needed to rise about 1/2 inch - give or take. This fit the need perfectly since there were multiple heights in the package. I did not need to worry about calculating the height of tile plus underlayment plus mastic

Outstanding replacement parts for our Kohler

Would Recommend

The Oatey Set Rite 7.13 in. Red Plastic Toilet Flange Extender Kit worked unbelievably well with our Kohler Comfort Height Commode. So much so that it reminded me of Al Bundy’s Ferguson when it flushes. It actually sums the lights. IYK,YK

Didn’t like doing it twice to make it nice…

Would Recommend

Liked the different disk size(s) made it easy to fill the gap to within 3/4” needed for wax ring. The gap after tile and mortar bed made the flange about 1-1/8” deeper for a standard wax ring so adding an extra wax ring failed on me twice over 10 years and causing me to remodel the first floor ceiling.

Very easy install to add height

Would Recommend

This extension set worked perfectly to get my toilet up to the new finished floor height. There are spacers from tiny increase in height to quite a large increase. It is very easy to install.

Easy to install

Would Recommend

I was replacing my toilet and realized the flange was well below the new floor. I got this extender and it has good instructions and is easy to follow. Make sure to read the notes because I kept trying to line up all the holes, and once I read the note that said it might not line up with the old flange, everything worked out. Definitely use a drill to get those screws into the old flange and sub floor. Now I'm ready to install my new toilet (as soon as the paint on my walls dry).
