Bathroom #2 Remodel Questions

[Thelazer]

Well Everyone. It's been sometime since I've been posting here.

You might recall I did the first bathroom almost a year ago. Now it's time for the second bathroom.

Here is my current situation. As you can see by the two attached photos I'm going to tear out the existing bathtub. I'll be using the Kerdi system and putting a tile shower in it’s place. I’ll extend it out so that it uses the full length of that built out portion of the wall. I'd like to not have to move the wall shower plumbing around if possible.

I'll also be doing a tile floor install.

From the photo (Bath1) you'll see that the existing bathtub surround is made from a laminate paper, put right on top of drywall and then stapled into the 2X4. I'm already assuming that this won't be strong enough for tile. Would I be safe to put hardbacker on top of this and then do Kerdi. Or, do I need to tear all of it out and replace with all new drywall then hardback.

BTW- you'll notice I already had to remove a bunch of drywall in photo (Bath2) due to water damage (no water got behind shower, it was the sink that leaked)

Thanks
Jay

Hi Jay, if you are using Kerdi you can just use regular drywall then Kerdi over it. You may need to fur one of the walls if so I would do the one opposite of the valve wall.

Thanks Mike. Here is this weekend’s progress!

I've removed the tub and look what I find. Looks like the plumber is going to have a little work to do. Luckily, the floor support beams are on either side of this black pipe. So the new drain line should be able to run under this with no problem.

The supply lines are another issue. I can’t figure out why they didn’t run them behind the wall in the first place ! Looks like this whole section of wall will need to come out.

In the 2nd photo, you can see where I've put some blue masking tape down. This is a very basic outline of where the new vanity, shower and toilet areas are.

I'm a little upset about the toilet. In my mind, it should have been against the other wall next to the vanity. I suppose, I could have the plumber move it. However, this is not a high dollar project so maybe I can live with it.

From your pictures that looks like particle board , not OSB on the floor under the tub. Maybe it's just my computer screen. If it is it should all come out.

Those look like CPVC supply lines. Are they used extensively in the state? The new trend is PEX pipe in Canada or else copper is the standard.

[Thelazer]

Yes it's particleboard. One of the curses of buying a "manufactured home" here in the state of Florida. Then again, I paid pretty much nothing for the place and live alone. It's a rare thing, most people I know have to have roommates in order to afford even an apartment.

I'm not to worried about the floor. My plan was to reinforce the shower walls, with plywood then Kerdi over them. As for the floor, also build it up with plywood first.

Hi Everyone.

I fear a major problem has now come up. Everything was going pretty smooth with the remodel, but upon the first water test of the shower, the floor isn't draining enough. Even worse, this is happening around the edge area. Any suggestions, I would prefer not to have to rip out the whole floor. Would there be a method to put new tile ontop, or use some form of a clear coating type product?

The water doesn't drain because there is no preslope, you need to take the edge tile out and re do it with slope down.You cant put no tile on top

Hi Jay,

Is this a question regarding the same project in this thread?

If so, I'll move this question over there. We like to keep all questions about a particular project in one thread. It makes it much easier on the folks that are trying to help you.

Jay, that partical board really does need to come out if you intend to tile the floor. When water hits that stuff, it swells. No good can come from a swollen subfloor under tile.

[Thelazer]

Hi, yes it is, please move it to the other thread.

I think it may be possible to remove just the edge tiles and fix those up with adding abit of a slop to them. I'll have to give a call to my pal who's been helping on this project and see if we can't come up with a way to do it, without making a big ol mess.

Welcome, Jay. If you go to the UserCP above, find Edit Signature and enter that first name there it will appear automatically in each post.

And the particle board needs to come out before you expend any more effort relocating plumbing and such.

And if you're gonna use the Kerdi Shower System, best not to install any plywood walls. The manufacturer's recommended backing is sheetrock. You could also use CBU if you want, but it's neither necessary nor the material of choice.

My opinion; worth price charged.

Just to clear up some of this.

A traditional membrane from Lowes was used. Cement board went down over that. Then cement on top of the membrane, then the tile.

Thanks
Jay

[bbcamp]

You used cement board over particle board subfloor, then your liner, then the setting bed. You have no pre-slope. Water that collects in the setting bed will not move to the drain's weepholes so it will just sit there and smell bad.

Please go to the Liberry and check out the Shower Construction Thread. You've gotten off on the wrong foot, and I'm afraid anything you try to do at this point will be a waste of your time and money.

You put the cement board inside the liner or underneath? Unfortunately either way is incorrect.
