[@MrRazor99]

Not to be a critic, your video was good but, if you're going all the way down to the joists, then you need to make sure that your subfloor is supporting your toilet flange.

[@Drewsroofingandhomerepair]

I would highly recommend painting prior to installing new floors!

why

[@4seeableTV]

@@lil0lizify If you're planning on painting and putting in a new floor, painting first means you don't have to worry about keeping paint off a new floor.

[@liosmanyolivares1798]

If you only replaced that damaged particle board and the rest of the bathroom is still particle board, I wouldn’t recommend leveling over it. Self leveler is mostly water based which can damage the existing particle board and cause issues over time.

[@LongDistanceMom]

This videos is super helpful my only problem is the amount of ads I have to skip 😢 and I get it that’s how you get money from the video.

[@JuvieFirst]

Your bathroom looks much better, although I am curious as to why you didn't have the off-color tile installed in the closet and use the matching tile in your little sink nook instead.

[@morganjones47]

Maybe if he got the flooring from a rehab store maybe there wasn't enough once the project was started. I had the same thought though.

[@mitchclem3404]

I have the exact same scenario. So looking at this video, not only am I having the subfloor fixed, but I'm possibly drywalling, painting and replacing the linoleum/tile?

[@Mike-tg7dj]

Thanks I don't know whether to be afraid or empowered? The people I am doing this for might not like waiting for the floor to dry( the wife and daughters) but, it is what is. There was one part I wish you had gone into and that was what did you use to cut the tile to fit around the toilet? Other than that I am good on everything else.I did also wonder what you did about wall behind the toilet because it didn't look all that good. Thanks again great video. Great public service!👍👍👍👍👍👍👍👍👍👍

[@lindachurchwell6586]

You should show how you placed the plywood in and measured around the toilet area so we could see each step ??

[@1whoFartsinthewind]

I would have built up the floor so that it fully supported the flange.A floating flange is a potential accident and or flood in the making.

[@denniskreiss]

Frank Davignon true Frank. However This cast iron pipe is going nowhere soon. And if it does it can only drop about a quarter to the floor. I used synthetic gasket which will expand to cover it.

[@marlowt2]

Drywall screws to secure subfloor...someone will be dealing with all of this again.

[@carlorachel]

If you saw the job I'm doing right now you'd get deja vu. It looks exactly-and I mean exactly-like your bathroom. I'm hoping I can get away with removing just about the same amount of subfloor. But I won't know until I get a bit more tile removed to see how far out the rot has gone. One suggestion: It might add value to your vid if you showed how you cut out the toilet drain hole before laying the plywood in. I loved your pace and perspective with the camera. Let's hope my job goes as smoothly. I've got the same cast iron drain waiting. I'm praying I don't have to use a set to create new bolts. I think we'll be OK. Thanks, D, for the encouragement.

[@ryancormack6934]

I wish you would have recorded what occured between 3:33 and 3:35. Especially curious how you got the subfloor under the toilet flange? (or is it the same size, it's hard to tell).

[@theshackthatdennisbuilt]

[@Iamthathillbilly]

Cut the cast off and using a rubber coupler put a new abs pipe stub up, lay your subfloor and put a new flange on top that can be secured to the sub floor and doesn’t have some old gold drilled back out in it. Also you need to put blocking between the joists at the joint between old and new to ensure the floor doesn’t have a spongy spot. This is a pretty lousy how to if you ask me

[@Jjernsberger]

Yeah, that flange needed to be replaced, for sure.

[@CANTORPASION]

thank you Sr , you are fantastic .

[@cgmaniac44]

Legit question and maybe I missed the answer in the vid, but why didn't you use any underlayment atop the plywood? Also, TY for your post regardless of all the comment complaints... IMO, there's plenty on KZbin to gather tips & tricks for a better grasp on DIY projects like this, but everyone has their own sworn by method and to each their own method. This is a job I'm doing now 1st time and it's definitely a challenge. From upstairs toilet flange fastened to only 1 joist and the unbalance over time caused a major water leaks flange straight down through subfloor layers down to my basement bathroom ceiling where it was showing the initial signs of warping and bubbles pooling in the drywall. So, a lot in hindsight I'd have done differently but there's only one way to do this job 1st timer or not AND that is to just do it... stop over preparing like I did, and make some mistakes because you will anyway. Due diligence in research and then trial and error, whomever doesn't give you the answer you want doesn't matter for your situation, just move on... there's plenty.

[@rockthelightGomer]

Thanks for the video! We found our toilet leaking a little, so we yanked it up and found our sub floor rotted. We have yet to cut it to see what happens next.... here's hoping the whole floor isn't shot!

[@alicequayle4625]

So is plywood or OSB better for the replacement flooring?

[@Nslinkar]

Skipped just about all the important stages. Did you reinforce the subfloor? How did you get the subfloor around the toilet flange so you can screw the flange to the floor? Cuz it looks like you over cut the hole. How did you apply the leveler?

you skipped an important how-to step sir... the step i happen to be seeking... how to create the hole for the flange in the new plywood. thought I'd mention that quick as i continue my search.

[@theshackthatdennisbuilt]

LilKing420s hey lil King. Good question. Once you get your plywood cut to size, and check to see that it fits. Measure from the front of the plywood to the circle, and from one side to the circle. Measure the distance across the circle. Find the center point of the circle and Mark it with an x. A simple way to draw the circle is to drive a nail in the center of the circle, attach a string the your center nail, and choosing one of your outside marks, pull the string around with your pencil... Making a circle. Have fun

[@michaelglaser1669]

The Shack That Dennis Built all toilet flanges are size of paint can.

[@scottlytton5328]

But shouldn't the hole in the plywood be smaller than the diameter of the flange so it can be bolted to the sub floor? I'm so confused

[@rigidrebel8781]

@@scottlytton5328 yes, if you have to replace all the way to the joist like he did, you DO need a surface to fasten flange to. This guy skipped a ton of steps, but you will typically have more than one layer to add if starting from joist. There are also ways to piece together under the toilet area. I suggest finding another more detailed video 😁

[@luv14lyf]

@@rigidrebel8781 you may have solved my dilemma. Doing a DIY bthrm remodel. We need to replace bad flooring under toilet and near one corner by tub (from water leaking under the tub door track. So we removed all the tile from floor leaving us with 2 layers of wood. So we initially assumed the bottom layer was the subfloor and the top was the underlayment but after a bit of web surfing, the first layer of plywood is only ½(15/32) so it appears the (top) pc of plywood (5/8) is also considered subflooring since the 1st layer alone would not be thick enough as a subfloor. So in totality the subfloor is 1"⅛? So When the house was first built years ago the builders technically didn't use an underlayment and tiled directly on and no additional material used as underlayment. So now we need to figure out what to make repairs with without ripping out the entire subfloor. Does this even make sense?

[@PAULEYBOY84]

Curious as to what you would price a job like this at? Doing same job. Could use a little insight please sir?

[@deadliftD]

The subfloor should have been installed in two separate pieces around the flange allowing you to slip subfloor under the flange so it can be secured to the subfloor.

What thickness plywood did you use? Can you use 3/4" or does it need to be thicker? Thanks.

[@theshackthatdennisbuilt]

It simply depends on whether or not you are matching existing plywood. 3/4 is adequate, but some floors like mine will have two layers of 1/2 or. Then you need to think about smooth face for laying flooring

[@m1kcan1]

My early 80’s house had particle board under the tile which was rotted after 40 years. Amazed it lasted that long. What contractor their right mind used particle board? Have to rip it all out and use plywood.

[@bluefrog85]

To anyone that's never do this note he's covered the toilet pipe so things can't fall in there- make sure to do this the moment you pull the toilet or you can easily regret it! All sorts of things have been known to fall in there and it isn't fun at all when they do! Best to just put something over it and keep everything out of it! Make sure to pull it out before setting the toilet of course... I've heard of bad stories going both ways where things fell in and one story where a guy put a toilet in and forgot to remove the bag he'd stuffed down the drain! Haha
