I’m building a curbless shower and wanted to know how deep I should step down the shower area? It’s an addition and I’m pouring a slab for the entire area of the new bath. The shower is 7’x4′ at the end of my 7’x17′ bathroom with a 3′ wing wall to keep most of the water contained. 3″ is what most of my contractor friends say along with a tile cont. too. He’s saying once the drain is set at two inchs above the conc. that is my benchmark or finish tile height. So allow 1/8 per foot from the opening. Any feedback on doing this would be appreciated. I’ve never done this before and would hate to demo conc. I know I can count on you fellow contractors!

This is confusing me - a double post?

Forrest - again
This was his first post found in General D. a couple days before the second found in Const. Tech. with a little more specific data not found in the first.
Sounds like he's looking for a little more clarification before he proceeds.
be proceeding

If you want a CURBLESS shower then you can't have a step down. That step down would be a curb.
Or are you talking about now much to depress the center fo the drain.
I can't answer that question, but I think that typically a curbless show the whole bathroom floor is treated as a wet area and sloped somewhat toward the drain.

A-holes. Hey every group has to have one. And I have been elected to be the one. I should make that my tagline.
The bathroom is 7'x17' but at one end is only the shower which is curbless. So the shower is 7' x 4' with a wing wall out maybe three to four feet parallel to the 7' for water splashing to much. The step down 3" is only the rough concrete with the drain set at 1/4 below finish tile height which is sticking up above the conc. 2-3/4 this is for drypack and waterproofing to slope to the drain. Since the drain is centered an 1/8 per foot puts the drain at 1/4 below finish tile height.
Does this sound ok. I have to allow drypack to slope to the drain and instead of a curb the starting point has to be below the slab. Correct? I just want anyones advice to see if they have done one or have found any flaws in my design.

I did one just as you are describing last year. The rough slab in the shower area will be below the finished slab in the rest of the bathroom by the total of the height of the two part drain top plus the necessary slope from the finished slab to the top of the drain LESS the thickness of your floor tile and a scoosh for the thinset.

You need to allow a minimum of 1/4" per foot slope to the drain. That means a minimum drop of 7/8" from one end of the shower assuming the drain is in the middle. Plus you need room for the actual drain assembly. Yes, this means the slope from the sides is greater than 1/4" per foot. Dry pack minimun is 1" I believe, but more doesn't hurt.
