Bathroom Remodel, making shower larger, concrete slab

[ArbitraryLife]

Okay, I am new here but have been trying to read quite a bit before posting... Hopefully this is in the right section...

Here is my issue:
I originally planned to keep the shower the same size, but recently have had the desire to enlarge it. As you can see in the picture, the original shower has been gutted, my issue is that I want to make the shower larger than the section of the flooring is recessed.

What are my options here? I was thinking of raising the drain and filling in the recessed portion to level with the rest of the floor, or remove more slab to match the recessed? Please help, I need a solution here in order to move on.


Thanks!

Welcome, ArbitraryLife. Please put a first name in that permanent signature line for us to use.

Plan A will work. I'd recommend against Plan B unless you happen to know exactly how the slab was reinforced and have room to properly reinforce a new dropped area (I don't see such room).

My opinion; worth price charged.

I'm liking plan A too.

You're doing more framing right?

[ArbitraryLife]

Thanks for the responses so quickly.. I talked to a plumber friend of mine and he agreed with CX, that the other parts of the slab most likely are not as deep as the recessed shower portion of the slab, and also might not be reinforced how I need it.

Yes, I will be doing additional framing.. the entire shower area will be enclosed with a curb for the door.

After I level the floor, and the drain is level with the floor, I should be able to do pre-pitch, liner, quick pitch easily right? Will I need to make the curb higher than normal to compensate for the height?

[Houston Remodeler]

Yes,

But we suggest you ditch the pre-pitch. You really don't need it. We trust that you can manage a sloped drypack bed all by your ownself. By ditching the quick pitch, you can skip the step of leveling the slab. We've even had gen-you-wine wimmin make their own mud beds

See where this is going ?

Added additional images to show the right side of the shower and the general floor plan. The right side of the shower will have a bench and a wall, I just haven't put it in place yet because I am waiting to see if I should level the entire floor.

[Houston Remodeler]

The bench doesn't have to touch the ground, it can be floating....

Hi Jason, welcome. I agree with plan A.

[ArbitraryLife]

Hi Davy, looks like you are pretty local to me. Now I have someone to call when I get in over my head? lol.

I have another question... What is the best way to raise the rough in for the drain? I plan to chisel out the current rough in, put in a coupler and extend the 2" pipe, put on a new drain rough in, cement fill it all in flush with the floor. Is there a much more simple method?

Should make for a fun weekend.

That's about it- Be sure to make the new clamping drain as level as you can get it. Mudding can push it around. Lowes sells the Tavy Tile Puck which we normally set atop the drain and leave it there until were done mudding as it keeps us from knocking the drain around and stuff from falling down the pipe.
