    Yes I have opened the hinged lid and the bolts really are metal.
    It is not possible to get to the nut at the bottom of the bolts as the bolts go into square box in the water compartment and it is porcelain all round.


    Perhaps the seat removes some other way?

Hi,

Generic procedure for these are :-

1. Remove the old toilet seat and any mounting hardware connected to it. Throw the old seat away as well as any old hardware. You don't want to mix up the new with the old.
2 Using a soft scrub cleanser that will not scratch the porcelain, clean the toilet surface where the old seat was attached. Don't forget to clean the bottom surface where the old hardware was attached.
3 Lift the hinge covers on the new seat before placing it on the toilet. Align the new seat to the mounting holes and insert the two bolts.
4 Thread a nut onto each bolt, making sure that the new seat is in the proper position before tightening.
5 Using the wrench and screwdriver, tighten the nuts making sure not to over-tighten them. Once the hinge covers are closed, the job is complete.

Kohler toilet seats are held on by plastic screws. If you cant get the nut on the bottom to come off then use a sharp chisel and just chop the head of the screw off.

Oh yea the screw head is located under a cap. Stick a screw driver under it and pry up and it will open.

How i done it on similar model - To replace seat. look right at where the lid hinges there is like two block about 6 to 8" apart. take a small screw driver and pop free the little door covering the screw head. take a big Philips or straight head screw driver. and then look under neath where bolt would stick out below. and you will see a nut,you should be able to hold nut by hand as you tighten the bolt. both nut and bolt are plastic. draw good and snug.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

    Thanks for your response!!

    OK!! So, you have the different Model. They usually have 2 common models.The procedure for your model would be :-

    1. If you have one of the Kohlers with the Kohler anchor bolts holding the seat, do not buy the $46 anchor bolt kit 84999.
    2 Instead, remove the old anchors and bolts which have an aluminum end which the stainless bolt screws into and over time become corroded together. Use a 1/8" drill and drill around the bolt removing the anchor material until the bolt can be pulled out.
    3 Carefully clean the hole with a 11/32" drill to remove all the remaining anchor material.
    4 Then go to your local hardware store (ACE) and buy a 10-32 3/8"x3/4" rubber expansion plug (check to be certain the threaded part is brass and it has a shoulder on one end), a 10-32x1.5" Phillips bolt and a couple of small fender washers to fit the seat. Total cost under $4.00 for two.
    5 Assemble being careful to not tighten too much and crack the porcelain.

    Let me know,if needed further assistance.

    Hope i helped you.

I can't get to the nuts on the toilet seat in order to loosen them so I can change my broken toilet seat.


I just had the same problem.I can not believe that kohler would design such a flaw. I have four of these toilets in my house,and it would be ridiculously expensive to replace, especially for a seat. To fix it I went to OSH and got some 1/4-20 T nuts, went home cut the bolts off the seat (multi master dremel) with metal cutting blade. With a screw driver tapped the bolt and the small area around the bolt down into the toilet area. Now you have just a porcelain hole. Clean area with solvent (lacquer thinner),get some gel type super glue from hobby shop and put it on inside and top edge of the hole on the toilet. Put some glue around the shaft and under side of the T nut and slip it into the hole.Then put a SMALL bead of glue around where the T nut makes contact with toilet and let it dry aprox 1/2 hour. Now you have a permanent fix.To prevent a problem getting the bolt out in the future,put some anti seize (auto part store) on the threads of the new bolts. Hope this helps.
Good luck

How do we replace the seat on a Kohler K-3386-0 Rialto one piece toilet? The screws/nuts holding the seat down are inside the toilet and aren't accessible. Is there a way to replace the seat without...


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

Get seat of Kohler K-3386


Roberta3fan could be giving bad advice based on experience with other toilets. This does not seem to be an option for this toilet design. I am in a similar situation and it appears that the nut (and it is a metal bolt) is not what you would expect. Here is a picture of the anchor kit for this toilet seat: http://www.plumbingsupply.com/images/kohler-anchorkit-84999.jpg I am going to assume that the sleave that should be engaging the bolt is cross threaded and try to grab it with a pair of vice grips. I'll let you know if it works.

What is the best way to remove stuck toilet anchors


try rotating the entire toilet counter clockwise so the bolts are in the insert slot of the toilet flange and rotate the nut and the bolt head should line up and pop free of flange.

Kohler lowboy toilet seat does not have bolts underneath


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.

Can't change the toilet seat that broke on kohler rialto


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.
