We have a one-piece Kohler toilet. We bought a new seat for it. The problem is that after my husband removed the old seat, one of the screws will not come out. It just keeps turning and turning. What should we do? Thank you.

You should be able to get it direct from Kohler unless you can't find it at a specialty plumbing shop .

need help.ours started leaking in the front of the bowl

Kohler will try to sell you $46 anchor bolt kit 84999 & also there special tool. You should expect that for a $400 toilet.

Try this instead:
1. Use 1/8" drill bit and drill and drill around the bolt until the anchor material can be removed.
2. Carefully clean hole with 11/32 drill to remove all remaining acchor material.
3. Go local hardware store & buy a 10 - 32 3/8"X3/4" rubber expansion plug (make certain threaded part is brass & has shoulder on 1 end), a 10 - 32X1.5" Phillips bolt and couple of small fender washers fit the seat.(about $4 for 2)
4. Assemble carefully not to over tighten and crack the porcelain.

Hope it helps

I repaied one of these laast week and it had the Plastic nuts in between the webbing on the seat where the lid connects I believe You remove the plastic cap with a knife and use a flat tip screw driver to remove the screws and replace the seat.

Get a new toilet seat. I don't know anyone who sells the hinges.

Now isn't that a trick. Epoxy! The bolts,now studs, must be quite short. Well, glad you got it resolveve. I hope your house has more than one restroom..That epoxy will need a day or two toset up properly. :) Thank you for the reply. We all learn from each other.

I have the same low boy where the bolts are inside the hollow body of the toilet. I called Kohler customer service and was told to use brute force to yank the toilet seat out. My husband suggested using a saw to cut the bolt but he hasn't done it yet. He wants to replace all our Kohler low boys which constantly leak becos of poor design of handle and flapper. The handle pulls the flapper slightly to the side when you flush. And the flapper lip being a tiny bit too small, if it doesn't sit just right, the toilet leaks. We've replaced one already with a Toto and love it. Too bad that Kohler isn't trying to fix the problem as I see many many online posts with the same problem and recommendation to replace the Kohler with Toto or somethng else.

If your problem is like mine your toilet seat is loose and swivels when you sit on it. If you try to tighten down the screw it won't tighten. Use instructions above to remove old hardware.

To fix with new hardware

Purchase Hilti brand 3/16" x 2-1/2" Toggler Brand Toggle Bolt (Home Depot sells the kit). Kit comes with 10. You will only need 2. My last repair lasted about 8 years (with new kit = 40 years left or the purchase of a new toilet - whichever comes first). Set comes with 3/16 flat head screws. I recommend purchasing 3/16" 2" round head screws with matching flat washers. Sink Metal Toggler into hole with toggler pointing straight up (it's attached by long plastic legs). As it goes in the hole it opens up. Pull up on the plastic pull rings as tight as you can until the toggler is tight up against the inner porcelain of the bowl (similar to tightening cable ties). Line the seat up with the holes and it's new plastic adapter (that won't slip into the hole courtesy of Hilti). Slide washer underneath round head screw but on top of toilet seat assembly and screw directly into the newly installed toggler which is sunk in bowl/abyss receptacle. Repair should take around 5 minutes.

your new seat will have bolts and nuts with it.
