First of all, there are a million tutorials out there on the web about how to replace/install toilets. I drew on about 500,000 of them in preparing for this project. But I figured I would write my own, in case showing you that even a plumbing newbie like me can do this gives you confidence to tackle a project like this yourself.
The impetus for this was that one of the bolts attaching our toilet to the floor broke. Apparently the ones we had were made of plastic, and it seemed to have become corroded.
It wasn’t an immediate emergency — the toilet still seemed to be sitting snugly in place — but we wanted to deal with it before it actually became an issue since generally it’s important to have two fully functional bolts attaching a toilet to the floor. To avoid leaks and other catastrophes that could cause structural damage. So I’ve heard.
Anyway, the only way to detach a bolt and install a new one is to remove the toilet, because the bolts attach from below. Thusly began our toilet replacement adventure.
First, turn off the water to the toilet by turning this little knob at the bottom of the water hose connecting the toilet to the water supply:
Then flush the toilet a bunch of times to get rid of as much water as possible. Everything you can’t get by flushing, soak up with a sponge. Don’t worry, it only gets more unpleasant and unhygienic from here.
Then detach the water connection from the back of the toilet, which just involves unscrewing the collar by hand.
Next unscrew the nuts on the bolts holding your toilet to the floor (only half the work if one of them is already broken off). With someone stronger than yourself, lift the toilet up, straight off the bolts, and place it on its side on a towel (soft surface is important so you don’t scratch or break the bowl).
You will discover some terribleness:
This is not cause for concern…it’s just how it looks underneath a toilet. Basically what you’re seeing is the remains of the wax ring that creates a water tight seal, and then underneath that is the flange which is what the toilet bolts into. Also rust. But nothing more than that, it’s not sewage even though it looks like it could be. Oh and the red thing is just a cloth you put loosely into the flange opening to prevent gross odors from coming up into the bathroom (it’s okay if your cloth is a different color).
Then scrape off all the wax (a new wax seal is needed every time you install/reinstall a toilet). Bonus points if you do all this immediately after running 8 miles without changing out of your running clothes. Even so, you won’t be the grossest thing going on in there.
Remove the two bolts from the flange, and then put in the new ones that come with the new wax ring kit you’ve bought at Home Depot (pay $6) — unless the box only says there are bolts inside the kit but they aren’t actually present inside, in which case you will need to halt the project and drive to Home Depot to complain and request an exchange.
When the bolts are finally installed they should be sticking up like so, ready for the toilet to be set back on:
Then install the new wax ring. Here’s what it looks like:
The wax ring attaches to the bottom of the toilet, so you need to prepare the surface by scraping/wiping off the leftover wax from the previous ring.
Then lightly press the new ring around the opening — you want to be sure it’s pressed hard enough to stick to the toilet when you flip it right side up, but that you don’t squish it prematurely. You will probably find this to be nearly impossible.
Then lift the toilet to an upright position and lower it into place so that the bolts come through the holes in the bottom of the toilet. This needs to be done very carefully because you only get one shot at making contact between the floor and the wax ring — if you have to reposition it, you need to start over with a new wax ring because partially compressing it and then removing it will prevent it from creating a tight seal.
At this point, you want to be sure to slam the toilet down hard enough to crack the bowl. If you’re really good, you won’t notice the bowl is cracked until you finish screwing the toilet back in, reconnect the water, and fill the tank back up. At that point, you will try flushing and see water leaking from the side and realize you didn’t succeed in creating a water tight seal with the wax ring. Then you will notice the slight crack across the front of the bowl, taunting you with the threat of future calamity.
Now you will probably be cursing and wondering why you ever bought a house, and why you ever thought you could install a toilet yourself rather than just calling a plumber. Your husband will look at you like, “why did I marry a crazy DIYer who insists on doing things herself when professionals exist to do this?!?”
At this point, you will have to go buy a new toilet from Lowe’s (obviously you should avoid Home Depot, since they burned you earlier on the wax ring kit). If you buy one with a fancy new feature like dual flush, you can convince yourself that this is a better outcome anyway and you’re glad this happened. (Pay $123)
While you’re at Lowe’s, you should pick up a wax-less sealing product that lets you reposition things if needed, because that wax ring is disgusting and this “you must get it right on the first try or start over” thing obviously does not work for mere mortals. (Pay $12)
Return home with your new toilet and wax-less ring, ideally stopping at Wendy’s along the way to stave off a low blood sugar meltdown. (Pay $13) Repeat all the steps from the first half of the tutorial to once again drain and remove your old, now-broken toilet. Put your broken toilet in your front yard to await trash day and make the neighborhood nervous about their new neighbors in the meantime.
(Note: on trash day you will likely come home to a threatening note from the town saying that toilets must be disposed of privately, you will be fined if you don’t remove it immediately, and you would have known this if you’d read the “toilet installation” permit. A permit to install a toilet?!? I don’t think so. Call the junk removers, pay $100.)
This time, rather than applying a new, gross wax ring to the toilet, install your wax-less sealing product directly on the flange:
Then follow the installation directions that come with your fancy new toilet. Most likely it will involve lowering the tank directly onto the flange again, this time refraining from dropping and breaking it. If you’re smart, you will have purchased a new toilet where the tank detaches from the bowl, making it about 500 times less heavy and unwieldy.
Once it’s in place, screw the nuts on the top of the bolts to secure the toilet to the floor. You want to get them tight, but not too tight because you can easily crack the toilet. Have someone sit on the toilet to test it for rocking, and curse at how long it takes you to tighten them enough so that it doesn’t rock.
Once you finish assembling the toilet, reconnect the water hose to the back of the toilet, and turn the water back on. Cross all your fingers and toes that water doesn’t come leaking out the side.
You might think you’re done here, but you’re not. What you’re going to want to do next is invite some friends over to show them your new house the following weekend, and while you’re giving them a tour of the basement you’ll notice water leaking down from where the bathroom is. At this point, you will feel like a failure as a homeowner, and dejectedly call a plumber. He will be ridiculously difficult to pin down to a specific schedule, will insist on coming during business hours when you’re supposed to be at your job, and will charge you a hefty fee. (Pay $100) He will explain that the waxless rings aren’t trustworthy, and good old-fashioned gross wax rings are the way to go. You will curse the additional cost, but at long last your toilet will be fixed!
Until you are hosting 22 people in your home for Thanksgiving a month later, when once again you will notice water leaking into your basement. First try the same plumber that you had last time since he clearly didn’t do the job right and he should fix it for free. When he doesn’t return your phone call for a week, give up and start desperately calling other plumbers. Since you can’t take off any more time from work, splurge for someone to come on the weekend. (Pay $150) This will likely require sitting around the house all day since plumbers refuse to specify exact times and instead just want to “call you when [they’re] in your area.”
When the second plumber removes the toilet, he will find that the wax ring the first plumber installed was not squished down properly to create a seal. Console yourself that at least you’re not the only one who failed to install a toilet correctly — a professional who took your money couldn’t do it either, apparently!
The new plumber will use a “double high” wax ring for maximum sealing, and finally you will be done. Maybe. Four months later it’s started to rock a little again…let’s just burn the whole house down?
So that’s my toilet installation “tutorial,” I hope you found it helpful!(Sharing at DIY Showoff, Think and Make Thursdays, Tip Junkie, and Sunday Showcase)
