Before You Buy a Kohler One Piece Toilet, Watch this Video on Replacing a Toilet Seat.

[@mwycombe]

Excellent source of information on how to tackle this problem.Thank you so much. I found that Home Depot no longer stock the Everbilt 1 1/16" expansion (or well) nuts. But my local Ace hardware store had a drawer with 1 1/2" #10-32 well nuts for which I got #10-32 3" stainless steel pan-head screws. These have a much more substantial head than the #10-32 1 1/2" Everbilt screws and are needed to reach the 1 1/2" well nut. Be sure to put the #HK36 adapter over the well nut before you tighten the screw to expand the well nut and wedge it in place. On my first attempt the screw was drawn into the soft rubber of the well nut and would not come out so I had to sacrifice it by drilling it out and then doing it the right way with the #HK36 adapter in place before cinching up the well nut to wedge it in place. The EverBilt stainless screws have puny heads and you should insert and extra washer into the #HK36 adapter before tightening it up to prevent the screw head pulling through the #HK36 hole into the well nut soft rubber upper.

Where do you find the adapter at? I’m in a pickle now with this toilet seat. Thanks for the helpful information

@@Meem715 i use shoe goo to glue in standard bolts. dont bother with any kohler parts again.

Thank you so much for this video. I wanted to replace our toilet seat and found that one of the anchors was spinning. Before I went to far with the project I found your video and am glad I did. Before I cut anything off and ended up at a dead end and without a seat I ordered the anchors you suggested. With the knowledge and guidance you provided I was able to remove the old and install the new in half an hour. Thank you again!

[@davidcomora]

Fantastic! Thanks for letting me know!

[@rayb2001]

I'm glad I saw this. My toilet seat was discolored but not broken. I couldn't get the bolts to turn but before I went down the route you did, I ended up sanding mine to remove the discoloration. It's not ideal but saved me a ton of headache! Thanks for struggling through this as I would have duplicated your trauma!

[@edgrossman8929]

This is a design failure

[@scott4191]

Very grateful that you made this video. I recently purchased a home that had this toilet installed and I came across this indefinitely spinning of the screws. Your solution saved me loads of time! Thank you.

[@AlanChan-p9n]

Thank you so much for doing this video. I struggled with the same problem for about a year and was not able to remove the bolts no matter how much wd 40 I put on them. After watching your video, I was able to remove the bolts and the expansion nuts. I got to Home Depot and was able to purchase the screws and the expansion nuts but I could not find the adapter from Bemis. The new toilet seat I bought came with 2 plastic bolts and wing nuts which were intended for a toilet that one could get to the bottom and screw in the bolt/nut. So I took a hack saw and cut off the head of the plastic bolts, drilled a hole in the middle of each bolt head and used them in place of the Bemis adapter. It worked!

[@dawnhill5879]

Thank you so-o-o-o much for this step-by-step video, including holding up the packages you used for each piece. I wrote it all down and then went shopping at Home Depot. Can't believe it took me TWO YEARS to get the toilet seat replaced, and it should have only taken 15 minutes. Like another commenter, I couldn't find the adapter kit you held up for the Bemis seat. I had purchased a Bemis/Mayfair seat like you did, so I just called the Bemis -800 phone number. Lo and behold, the super-helpful customer service woman sent me an adapter kit FREE that I received in two days. It had a whole lot of pieces, (including some that may have been useful instead of the expansion nuts [although they looked a little too wide]), but the white nylon adapters that you showed were exactly the same. Ya hoo! Keep on recording, David. Your video was one of the most helpful I have seen on any topic.

[@davidcomora]

Thanks Dawn, I so glad the video was helpful!! Crazy stuff!

[@IhateCCP]

I am at 3 months' mark. Today new dremel bits arrived. Looks like it will probably take me another few months.

[@viviangude2789]

I didn't have a problem with removing the bolt and anchord, but couldn't figure out where to get the parts. Thank you for this very instrictive video.

[@cskcsk9744]

Thank you! I followed everything, My old seat was still attached - I got one anchor out because it broke while trying, then yanked on the seat until the second anchor came out. Installing the new anchors- yep I broke one of Kohler's $12 aluminum anchors, and had to drill it into the cavity in the toilet. Waiting for a new set from Amazon, so I'll get 2 more chances. yay!!

[@davidcomora]

How did it work out?

[@cskcsk9744]

Got it done with the new anchor! Got the new set for free, returned the first one to amz as defective. I will never buy a one piece toilet

[@davidlpuckett9820]

Your video was an absolute lifesaver - thank you! I've never had so much trouble with a dang toilet seat. Such an incredibly bad design! Thanks to you, I pried the dreadful metal expansion nuts out, went over to Home Depot and got the rubber ones you suggested, and sorted it. No more Kohler products for me!

Oh my god THANK YOU. I just bought a house and it came with a shitty (no pun intended) one piece Kohler with loose rusted bolts. I literally took screenshots of the pieces that worked for you and am going to find them now.

Same issue. However I went down this path serval time, just like you, maybe more. But thank God for your video. I was just about to order another Kohler anchor. But started another round of my KZbin search and found your video. I am going to Home Depot and maybe Menards TODAY. Thank You. 👍

[@AlanBrody]

This was a great source of information. I probably would have been talked into a new toilet if I hadn't seen this. I found the expansion nuts at Menards and bought stainless steel screws and washers. At the end I had the original seat firmly in place. Fingers crossed that it will be easier if there's a next time.

[@LisaMinneci-m4i]

So helpful, David! Just ordered everything at Home Depot. Specifically, Everbuilt Expansion Nuts #10-32x1-1/16" in brass and #10-32x1-1/2 stainless steel machine screws and the Kohler Seat Anchor Kit 84999. I threw in a few washers as well.

[@davidcomora]

Christopher, I'm so glad to hear it helped you avoid some of the insanity others have been going through.

[@nibornm1]

Hi David - a very helpful video and here here - what a pain it is to try to do this! You helped me figure out that I could remove the anchor, which snapped halfway down its length, even after I used plenty of WD-40 to attempt to overcome the corrosion. I ended up placing an 1/8" thick piece of rubber onto the porcelain, then a 1/4" thick piece of oak and then using a pry bar to pull out the screw and anchor. To provide a new anchor I ground down a 1/2 nylon dry wall anchor and glued it in place with epoxy resin. I then used a stainless steel sheet metal screw of the right diameter (+ a the original washer) which held the lid hinge firmly in place. Mission accomplished.

[@davidcomora]

Wow, very ingenious!

[@dericktrx7573]

Dang! Man your luck is as bad as mine. I would never get a one piece ever. And that one there you have I would have pulled it up in a heartbeat and junk it. Thanks good video to watch.

[@kimstringer-taylor8721]

Thank you so much for sharing this. I bought a Sanilo seat which is said to fit all manufacturers’ toilets. But low and behold this was not going to be my normal replacement process. Exact same problems as you described. And reaching Koehler and Sanilo support has been frustrating. I am 1 week in on this nightmare. But you have saved the day! I didn’t want any of the Koehler seats. This one matches the bathroom decor and is more sturdy than the original seat from when I purchased my condo. I can’t believe the drama? Again, Thank you so much.

@@davidcomora the new bolts worked just like you said. only I am an idiot. I got one in and the other didn't catch. the rubber looked like it fell off into the toilet after turning it forever. I ordered more. when the new ones came, I realized that the old bolt had just shriveled up when I turned it and had not broken. I used the old one and have spare bolts now.

[@lisaadams780]

Thank you. I remember the toilet had a lifetime warranty. I wonder if Kohler will replace it or send and person here to change the toilet seat. No one wants to do it for fear of braking the toilet. We are having the exact same problem. Bought a toilet seat over a year ago and couldn’t get it off. After watching your video now I know why we are having a problem. They need to stop selling these types of seats. Also Kohler toilet seat then was $50 to replace it. That is just unbelievable to me and I will never hold this company in high standards anymore. We still have not been able to remove the seat.

[@jenm6476]

Mine has these black pieces that allow quick release of the toilet seat. I purchased a new insert and had to purchase a new screw the other one superimposed to the insert. I out the anchor in, put the bolt into the black piece and started screwing. Unfortunately, the screw stops and the insert doesn’t expand so it’s still loose. What should I should?

[@davidcomora]

@@jenm6476 i had that problem and had to find the correct size anchor. I used a rubber expandable anchor...the firat was too big, so i had to go smaller. Good luck !

Not bad...for a job that (on any other toilet) would taken 10 minutes max! But I'm glad I found your video. We need to change out one of these and this will be very helpful!

[@rayvaul3539]

97 Kohler 1.6 gallon one piece toilets??? My gosh that’s horrible I am stuck with one and I can’t twist the screw wing twist since the hole is like half an inch in diameter or something like that. Why on Earth would Kohler make such a badly designed toilet in which you have so much trouble changing a seat???

[@oralrobert33]

I used a hand grinder to eliminate the bolt head which heated the bolts to the point where all the plastic parts melted. I broke one bolt by bending it back and forth with vice grips. The other one just pulled out; probably could have done the same thing with a torch because I never had to completely grind the heads off. I then had to enlarge the holes from 3/8 to 1/2 inch to accept the Kohler seat anchor. I used a carbide bit and had to keep cooling it off in the toilet water. Probably not the correct bit for porcelain but eventually the job got done.

[@billyoung1826]

David, you are my hero. I have a Toto soft close with the same issue and yours is the only helpful video I found. The replacement directions on our model are straightforward however ours is CONCEALED like yours with no way to access the tightening nuts provided without tentacles (which I do not possess). I don't know why toilet designers do things like this, there are many working designs around this on later concealed toilet designs unfortunately ours is an older model before reason and common sense kicked in. I'm now off to Home Depot or Amazon for expansion nuts. Dumb things drive me bonkers and I can really feel your pain. I'm glad you resolved this nonsense and hopefully I will too.

[@davidcomora]

Glad the video was helpful. I hope it all worked out!

[@viviangude2789]

I tried everything until I finally stumbled upon a merchant at EBay who sold the correct hardware: the expansion nut with the hex hedge screw and the regular screw, and also the bolt that made it possible to hold the hex hedge screw in place while tightening to expand.

[@minipluscreations758]

So you couldn’t screw the bolt from underneath inside the tank? I stuck a stick through the hole and it went through inside the tank. I’m not looking forward to it but I’m going to try putting my hand inside the tank to tighten the bolts.

[@davidcomora]

How did it work out?

Thank you for this. I had to use a wall anchor in the hole but it’s not very solid. I will try and find the parts that you used.

[@deplorableme1777]

I have a K3402PB one piece from 1988. The bolts/nuts are accessible inside the tank

[@bernardsolnik2909]

If you have to pull the bolt out, it can be helpful to hit it sideways a few times to loosen it. Hit it in one direction once, then in the opposite direction once, and repeat this a few times. I also had to drill one of the bolts out, and I started with a very small diameter bit angled at about a 45 degree angle and drilled to eat away at the metal. I gradually worked up to slightly larger diameter bits, never having to get all the way up to the 5/16" drill bit the Kohler mfr's official seat bolt anchor replacement video recommends. Use cobalt drill bits. Once the anchor was loosened from drilling on it, I pushed it down and it fell away.

[@rohitnijhawan5281]

how did you "pull" the anchor out? did you have to use a drill again?

[@tomking1890]

I just bought one, and they changed the design so the seat bolts go all the way through the porcelain. Thumb screw on nuts hold it in place, very simple...

[@michael69040]

Isn't there a toggle type fitting that would work? Also, of course one would use stainless replacement . The original bolts are stainless and thus impervious to a regular hack saw blade. I got the hold fittings out through a few ingenious maneuvers and while the seat was off it was easier to hoist the one piece Kohler with my home made toilet "transporter" which all plumber already have-of course in professional form.

[@meltonkentjr1226]

With the Kohler one piece toilet you have to remove the tank cover and reach inside under the lip where the bolts are supposed to be and unscrew them. I just changed seats on my Dad's and it was a bit of a headache but he LOVES that Kohler 1 piece. I made sure to use the metal washers on top but bought 4 ⅛" rubber washers, 2 lock washers and 2 nuts from the hardware store. I placed 2 rubber washers on top and 2 on the bottom with the lock washers and nuts and tightened them up with no problem.

[@TheArozconpollo]

Nope. This toilet the bolts are blind, not accessible from inside the tank, not accessible anywhere

[@garycooper1627]

I have exactly the same problem as you. I bought a Bemis replacement toilet seat thinking that it should be an easy install. Wrong, as you point out. I could not get the screws out that hold the old seat in place. In watching your video you talk about a Bemis kit that allows you to use the Bemis seat on the Kohler toilet after replacing the Kohler anchors. It looks like the kit is Bemis part HK36 (as shown in your video). I can't find it anywhere. Where did you get yours? If I can't find the kit I'm going to just replace the toilet with another and it won't be a Kohler one piece! Thanks for your video. It really helps.

[@johnh7789]

I just used an expanding rubber anchor from ace hardware. The seat was still a little loose because I should have bought larger anchors but I used contact cement to keep them from moving. The anchors and screws cost about $5.

[@bobbrown5951]

I went through this like you did (seat kept coming loose) but the problem is that the rubber covered "well nut" or "cavity bolt" which is the next size up is too big. Lowe's had them all on display. Can't get it in the hole to even start screwing the bolt in. I got one of the Kohler metal anchors (they're now on Amazon) and was able to install it by pushing down on the screw when I fastened the seat. And I didn't need that overpriced tool kit Kohler tries to sell you for installing it.

[@equality7_2522]

Is this a Rosario model 3434BB? The model number is printed inside the tank.

[@davidcomora]

I believe the model number is 81818AA

[@gjurczyc]

Did you see the 84999 Anchor set with the remoal tools?

[@davidcomora]

I bought a kit from Kohler, not sure of the model, but the expansion screws broke upon installation. So the rubber expansion screws were a lifesaver. Is there new kit?

[@fitnesscanbefree1836]

What did you use to drill out the headless bolt? I am presently at that stage lol

[@davidcomora]

Once the head of the bolt was sawed off, I used a steel rated drill bit that was smaller in width than the bolt and drill down in it about a 1/4 of an inch. Then I used an old drill bit and a hammer to push the bolt down into the fixture. Since you are dealing with ceramics, you need to be careful when you pound down... so if you need to drill further to make the bolt pliable enough to pound through, it might be a good idea.

[@michaels2470]

This toilet came with my place, I was going to replace my toilet seat bc it wasn’t soft close. Noticed I couldn’t get the screws out but after seeing this I think I’m just going to live with it. What a nightmare.

[@scubasteve6462]

Can you find the toilet seat adapter at Home Depot?

FYI: Call Kohler and you should be able to get the kit. I wonder if they have done anything to correct this problem? Mines 18 years old and while I did get the kit from them for free i never did use it as we were afriad it would crack and were not paying someone 150 to do this. Frankly, I cant believe a company of there size and supposed experience made this mistake or am I missing something.

[@davidcomora]

I thought I might have had a lemon, until I posted this video and saw all of the other folks who had the same issue! I actually got the kit and one of the anchors broke and kept turning after I installed.

[@mikerapp8163]

Basic issue is that installers don’t use anti seize on the bolts. If you don’t, you will face what this video depicts. This video is great for all the steps you should not take.

[@limitedblkwrx]

I replaced my anchors with genuine Kholer ones 3 years ago and when I did I put tons of anti-seize, but the anchors still stripped out while I was unscrewing them to replace my seat today. I think these Kohler anchors are just a terrible design.

[@paulbellamy196]

A second issue is mixing two metals, brass and stainless steel in a wet environment and not expecting them to corrode into each other resulting in a solid mass of screw/anchor that either spins in the porcelain hole or is frozen in place. I’m thinking of getting a brass screw to replace the stainless steel one in the 84999 parts kit.

[@joelauri4138]

I repair these a lot. Trick is getting old bolts out and not over tightening new inserts. Unless your very handy call a plumber, retail for the kit is 30 bucks and I normally charge 150 in labor. Remember folks it's not what ya do it's what ya know.

The second bolt is not coming loose, so I soaked it in KROIL… will try again in the morning. Then I took a photo of the model number on the inside of the tank and sent it to Kohler.

I watched the Kohler video on how to replace it and they cut when they talk about removing the old flapper bar. They cut, because its very difficult to pull the old bar out and they don't want you to realize how tough this is. Not surprisingly, they have also removed the ability to post a comment below their video, as I suspect many customers were complaining about how difficult the process is. I may make a Toilet from Hell, Part 2 video to show what is involved in removing the plastic flapper bar.

Supposed to also have a lock washer with the anchor kit

[@Mikemanray]

I bought the metal Kohler kit and it worked ok to put a new seat on. But now about 3 years later we want to change seats again. The anchors are just spinning. I can’t pry them out. The ‘wrench’ they included with the kit can’t get enough grip on the anchor to hold it while I break the screws loose. They must have corroded together. I hate this toilet so much. Thought my issues would be solved forever by buying the official kohler anchors. I might try slide hammering the screws and anchors out. If the toilet breaks, I will celebrate as I throw it to the curb.

Believe it or not, I'm still at it. It has been almost 2 months. Could you, please, answer me this? The anchors contained in the 84999 seemed too narrow for the holes in my toilet, a Kohler Rialto, in spite that they recommend this part to fix my toilet seat. Is it maybe so that it doesn' t matter, since the expansion nut will expand anyway? I can't find any of the other nuts and screws that you and some other people talk about. It seems that Home Depot is no restocking a lot of things, maybe because there are problems with the supply chain. At least in Miami.

[@davidcomora]

Ugggh....as I recall, i had a tough time getting the Kohler expansion screws in place, they seemed tight and then 1 broke. Mine were really tough to get in the holes. I had to bang them in and was afraid I would crack the toilet. I found the Home Depot rubber expansion screws worked great, but they need to be the appropriate size. They are pretty cheap, so maybe try a couple of sizes.

[@franschwabarnard6564]

Why dit you not just change the toilet? I just run into the same problem and for the price of toilets and labor involved to get this done I’m thinking better to go for other options and change

[@davidcomora]

I guess I have too much time on my hands! I accepted this as a challenge.

[@alexandraschinzinger3482]

Omg this is my life right now. Also Kohler toilet seat, trying to replace the seat 😭😭 will never buy a toilet like this again

[@fightingirishsi]

I hate this toilet!! Been going on for over a week trying to replace the toilet seat.

[@kentonbiiwabik3489]

Vice grip and pull up. Whole assembly should come out. Need to remove all the plastic pieces in most cases.

[@prettytootsies6406]

We rented a home with one of these pos. The lid looked so bad, like someonehad some major gangly piercings down yonder. Back to the lid, you have to give the anchors to the toilet gods, and drop them in the base. The new seat has anchors and if the seat needs replaced, repeat. This is a money maker for sure for them. Super nice shitter however.

[@jmuratoreful]

What toilet seat did you use? We’ve got the same stupid toilet and finding a seat that works has been a nightmare.

[@davidcomora]

I bought a standard Bemis and then had to pick up the adaptors that I demonstrate to get it to work. Once I figured it out, all has been well...though I dread the thought of replacing the seat in the future.

[@katipunan5]

Thank you

[@cengeb]

Get the correct flappers, and replace the seat, I have been running Kohler 1 pc 2 of them for almost 20 years, no such issues...Ya replace the flapper maybe every 4 years, and the actual valve after 15 years!

[@davidcomora]

LOL, I may make another video on how to remove the black plastic flapper bar from the back of the water tower. No easy feat! I noticed on Kohler's video that they cut at that point and then the video continues after the bar has been removed. I also notice they removed the ability to comment from that video as I suspect a lot of folks have been having difficulty removing the bar. I am about to replace my 10th flapper in about 18 years. Maybe my water is hard, but the other non-kohler toilets in my house have only had flappers replaced about 1 x in the same time period. This is not a cheap date!

[@cengeb]

@@davidcomora I use Fluidmaster or Korky brand or Kohler OEM flappers...I suspect Kory and or fluidmaster actually makes them anyway. The water tower with the snap in flapper in the back, ya have to make sure you have it proper height, otherwise doesn't work properly. Ya just stretch the thin part that goes into the holder, it snaps right in place...Water quality has a big influence on the flapper and the base it seals against last, for sure. I replaced my one Kohler seat with a new Kohler, using the tool kits from Kohler, inserts went rigth in, now I have a new seat that closes on it's own slow like, no more dropping it. the installation kit from Kohler makes it easy

[@admffun509]

At 10.03 the fun continues i laught so hardq but felt your pain.. im going threw it now thanks for the info.. kohler from hell!😂😂

[@davidcomora]

Hope you figured it out!

[@admffun509]

@davidcomora yes I got the screw spinning and loose then i lifted it about 1/4 high,.I put a glove to protect the porcelain from the steel hammer on toilet and the back of the hammer threw the screw. then I hit the steel hammer with plastic mallet it will raise it for me as I hit the steel hammer with the mallet.. so the steal hammer prys it up as I hit it with mallet.. it came off easy I struggled to use the recommended tools by kohler.. they weren't rigid, they were bending too much.. I used the steel hammer as a pry bar it worked flawlessly if u hit it with plastic mallet.. thank you for your help it took 2 weeks to go back was done in a 1 hr

[@ramonagudelo1888]

I had the same problem 😤😡😤😡😤😡

[@chromeluxx3853]

You missed a step on the anchor inserts. First tighten with lock and flat washers and then just the locking washer. If you overtighten the anchors they will break! VERY BAD IDEA TO REPLACE THE ANCHORS WITH CHEAP ONES!! You will never get them out and they will spin like hell when you try to drill them out.

[@davidcomora]

Tought to determine what is "over tightening" the rubber expansion screws have worked like a dream.

[@SuperHyee]

Thanks !

[@viviangude2789]

Unfortunately, I didint watch oyur video to the very end, when you tell that Kohler's parts are not worth it. So I ordered the kit from Amazon, just to find that the anchors were loose inside my holes: they are 6 mm in diameter and my holes are 9 mms. Now, I have been trying to find your Expansion Nuts #10-31, 1 1/16 in Miami and I cant find them. Neither in Home Depot, Ace Hardware or Ster Brothers. Can yu give me a hit as to where to find the hardware you are showing in your video, both the but and the screws? I'll be most thankful. Im about to get crazy trying to solve this!!! A toilet from Hell, indeed.

[@davidcomora]

@@viviangude2789 sorry to hear about your troubles. I did find the anchor kits at my Home Depot.

[@TheT1million]

Just found this video after 3 trips to the hardware store to change a toilet seat. I'm not handy, but my wife has started making fun of me for not being able to change the seat.
