  • Kohler toilet seat replacement

    Typically a simple task to remove a toilet seat. Not if you have a kohler 1 pc. toilet with built in aluminum anchors that are now loose and stripped. can't tighten the screws and can't loosen the screws.

    the homeowner had already torn the seat off the toilet and wasn't able to remove the screws. I used my die grinder with diamond blade to cut off the stainless bolts. the diamond make a very fine cut that doesn't heat up. also a regular abrasive wheel would create sparks and pit the china finish. once the heads are cut off, then i can punch the remaining stud back into the aluminum anchor. at this point i then peel the anchors top flange off and knock the rest into the recessed cavity of the china bowl.

    Once again a totally stupid design that kohlers famous for. making unique designs that don't stand the test of time. worst of all is the cost of the replacement bolt kit they try to sell you, the new seat and my labor to remove the damaged seat bolts. but on a 1 pc. colored toilet, it's still cheaper than replacing the toilet.

    toto at least uses a rubber well nut that squeezes and expands to tighten. not a perfect design, but a simple to replace design when need be.

    the remaining screws and post after the owner attempted to remove the seat. all they do is turn, doesn't tighten or loosen.

    a dremel might work, but a die grinder with a diamond wheel makes easy work of cutting the 1/4'' ss bolts.

      I hear you on Kohler design issues, Rick. Their current quick release/easy clean hinge system on their toilet seats is one of the flimsiest POS's I've ever had the displeasure of dealing with.

        Usually at this point they get talked into a new toilet. Once they hear the labor charge etc. they realize they aren't that attached to the toilet. Lol

          When you're installing a new seat do you normally coat the threads with anything so that when the day comes and the seat must be removed for whatever reason the threads will not be corroded and will unscrew easily. Granted it might not be you coming back some years later but it seems like the right thing to do

            Hey Rick. Literally just ran into the same exact scenerio today. SHE managed to get one out and knocked down. The other one was halfway out but galled and stuck. All she wanted me to do was cut the bolt off so she could knock it down. (I was there doing other jobs this was an extra freebie type thing)

            Anyway. I highly suggest the Milwaukee m12 dremmel tool!! Beats the crap out of using a corded hoss end grinder. Also because it's variable speed and with the abrasive wheels I used it literally had zero sparks.(speed and feed) Just a bunch of dust. I'm very meticulous and wouldn't have done it if it was going to mess up the China. Anchor fell through and that was that.
