Old House Bathroom upgrade

KBS

Hello,
My 4X7 bathroom is very old and I had to rip up the lanoleum and subfloor.Now theres just the unlevel floor joist.I would like to put tile down.Can I just use cement board and tile over that or do I have to have a wooden subfloor also.The toilet flange is cast iron and it is not level, just like the floor joist.I saw in another post that you mentioned something about using a floor leveling product, did I hear that correct.How would I go about doing this.Thanks KBS

Bud Cline

You have exposed floor joists at this time and no subfloor material in place, is that correct?

If so you CAN NOT install cement board over raw floor joists.

You will first need to install 3/4 plywood. Then you could install Self Levelling Compound.

But first, explain again exactly what you have to work with at this time.

KBS

I have no material yet, except I bought 3/8 porcelin tile.
The floor joist are exposed.
So then can I lay down 3/4 plywood and then the self leveling compound, how does that work?Then would I lay down cement board before tiling?My concern is the cast iron toilet flange..I dont want to make the floor to high...Thanks

Bud Cline

Yes. That's all you will need. The Self Leveling Compound will then serve as your tile base. No cement board needed.

Thanks for the information on the Self Leveling Compound, there seems to be a lot of prep which i dont know if I can comprehend all of the instructions and actually perform the task..Is there an alternative?If not maybe I can get some one to assist me.Thanks

Bud Cline

Not that difficult.

That is the alternative.

Post some pictures if you can---often leveling up the floor is easiest by adding new floor joists along side the old ones is the easiest way---

Hard to say without pictures.

This sounds like a first time job for you---ask plenty of questions---even if you decide to hire some help--knowing how a job should be done will still be useful.----Mike----

Hello, How do you know how much leveling compound to pour so you dont make it to high.
My concearn is when I go to tile, it will be higher than the toilet flange.
Thanks, KBS

KBS

Thanks for the information, I will try to take some pictures and post them.

First of all---put a wax ring onto that toilet flange and putty or caulk all holes----that leveling compound is thin and will flow into holes --cracks and toilet openings.

Read the label---Several thin layers of compound are used---check for flat between pours and stop adding layers when you are good----grinding off excess won't be needed if you do that----

DO the math!!! The instructions on on the label.

i dont advise to choose porcelin tile,coz it is bad for healthy ,wood floor or PC floor looks like good choice.

Another stupid comment possibly conceived from chemical abuse. Makes absolutely no sense.

English is a second language for Mary----
