Master Bathroom Remodel w/ Jacuzzi

Hey guys,

Well the master bathroom is on the docket next. I installed the jacuzzi tub yesterday and I'm getting ready to seal the concrete floor back up. I need help setting the height of the shower drain.

The shower is 40" Wide by 50" long or approx 3' x 4'.

What I believe I read is that the deck mude under the drain assembly needs to be about 1" thick. So does that mean I lay level across the concrete and PVC the drain to 1" higher than the bottom of the level?

Here is the drain that I purchased.

http://www.oatey.com/shower_drains/130.html

I'd really appreciate some feedback today since I have the concrete in my truck ready to go.

Thanks

Tom

Well I don't think I've given enough information so I'll add some more. Right now I've got a hole in the concrete slab. I'm looking down at the trap. According to the Oatey website they say to slope a mortor bed on top of the subfloor. However, I have a concrete slab home.

Should I slop the slab under the PVC liner or just the mud bed that goes on top of the PVC liner? Or both?

I think I also see that they base of the drain needs to be flush to the slab. Is that correct?

Thanks

Tom

You must have a sloped bed from the top of the bottom portion of the clamping drain the equivalent of one-quarter-inch per foot of run to the farthest corner of the shower floor.

Your pan liner goes on top of that, your final mud bed on top of the liner.

On a concrete slab, it's not necessary to have more than about a half-inch of preslope mud at the drain flange.

You'll find lots of information in the Shower Construction thread in our Liberry.

My opinion; worth price charged.

Last night I was able to set the drain and I was able to get the concrete laid down. Here are some pics.

Thanks for pointing out those liberry references.

I've got a question about a better bench. I just purchased the small better bench from contractors direct. I've got two questions about it.

1) If you had the choice would you install to the studs or over the top of the cement backer? If I install it to the studs the seat will become smaller and it will be more difficult to install the backer board.

and

2) What if the wall isn't quite 90 degrees?

Woops one more question

I was noticing the folding that has to be done with the rubber liner. Won't that cause there to be a hump in the wall where the rubber liner ends? How is this handled?

Thanks

Tom

Tom,

The thread that CX directed you to has the info on how to handle the liner. I haven't built a traditional shower, but I believe I have read that notching the studs where the liner gets attached or furring them out above the attachment point is what is necessary.

The Better Bench should be installed on top of the durock. When I installed mine, I made sure that I'd be securing it to studs (even though Innovis prints that it isn't necessary).

How out of square are we talking? Any way you can solve that prior to starting the shower. It'll make the tiling job look better.

Brian

I've got a couple of question about the shower.

1) I'm assuming that I only need to notch the areas were the liner will be folded. Is that correct?

2) Is the purpose of the wood blocks all the way around the bottom of the shower for the liner or is there another purpose?

3) What if there is a decent sized section where I can't put in blocks because the old copper plumbing sticks up through the concrete? Can I just omit this one area?

The new plumbing comes in from the ceiling.

Thanks

Tom

I like to see if I can get answers to the above please.

Yesterday I framed in the shampoo and soap nook and built the curb and completed the framing minus the 2x8 blocking that needs to be done. I have a goal to have the liner and mud bed installed by Friday night.

Tom,

1. 1/8" notch on the studs, 1/4" at areas where folds will be. dimensions
may be greater depending on your liner.

2. Yes. You can nail into the blocks above the liner.

3. Notch the back of the blocking around the pipes. Put a metal nail guard
over the pipes on the block.

How did your pre-slope work out?

Hey Chuck,

Lucky for me the slab was already sloped. All I had to do was slope my new concrete around the drain. I'm beyond a 1/4" per foot. So all good.

So is the blocking between the studs for the liner or is there another reason it is there?

I will get the blockign in there even if I have to rip 2x4's to get it done.

So the cement board just hangs down into the shower without any screws in it where it meets the liner? Edit: Actually I just remembered the mortor bed sits above the backer board so that should hold it in place at the bottom!

Thanks

Tom

Sometime this weekend I need to seal up the base of the Jacuzzi tub with Durock. Am I going to need to miter the durock to meet at the corners of the jacuzzi tub? Is there an easier way that I haven't thought of?

Another issue is after I put the PVC liner over the curb how do I put the cement back onto the curb? If I use Screws I will go through the liner?

Thanks

Tom

Hey guys,

Can I cement backer board the curb? Do I have to mud the curb?

Do I have to miter the hardi back for the jacuzzi jet tub to meet those corners? See the above picture.

Thanks

Tom

Tom,

You have to mud the curb because there is no way to fasten the CBU w/o putting holes through the liner. I don't understand your other question. You state "those corners"...don't know what corners you are referring to.

Hey Brian,

Thanks for chiming in.

If you look at the picture of the Jacuzzi tub it has sort of a Neo Angle shape. At the corners where the base runs parallel to the tub. Do I need miter the hardibacker or can I just run it up square leaving a cavity where the two pieces of hardibacker meet. Then just tile over the gap and miter the tile.

So what do you think?

Tom
