This is what I'm up to
After a round of ordering inappropriate tile for the shower floor, and getting 800 pounds of it returned, I’m a little gun shy about choosing again. I’ve fallen under the spell of a sliced pebble, tumbled Carrera marble, samples arriving today.
My County already approved the basic plan for a wet-room, a plan which didn’t include how to accomplish it. So I went back and got permission to cut up to 2” out of the 2x10 joists and sister. IF the plywood dropped too, as seen on TCTV (TileCoach TV) that equals 2-3/4” The level of the adjoining floor adds 9/16” leaving apx 3.3” potentially available.
The wet-room is partially divided into two by a half wall/bench topped in glass. A wall mounted toilet on one side, shower on the other. Two walls are exterior. This is a 90s era rambler.
Yes, that is an exterior door that opens into into the shower. I’m assured it is not the first one ever however it does seem to create pause. Objective beyond the door is to build a step-out porch (60”square) which ends up at the apx same height as the floor AND tiled with the same tile (so shower floor plus outdoor appropriate tile). There will be a threshold.
As far as specific functionality, the best place for the drain is as shown, placed the width of the wall in front of the exterior door. There will be daily going in & out of that door dripping wet both ways.
With a grand total of 3.3” of possible vertical space, is there enough room to build up from subfloor that is 3/4” ply over 2x10 joists 16”o/c. Tile probably will probably be 8mm and must have heat (Ditra, or…?)
Thanks in advance for checking this out and any advice.



Crickets…Ouch.
Ok, is it that I'm old? A girl?
Probably because I’m an Old Girl, lol that’s probably it?
You think the job is too tough for Granny?
Maybe, probably, but guys, don’t count me out. I’ve got some tools, attitude,
Pink is rocking the music here, and plenty of time. Looks tough, but not impossible.
I’m stubborn enough, I spent three years on merchant ships mostly working the roughest waters in the world, across the Bering Sea. I was in the engine room, an oiler.
One of the first things I learned is basic marine engineering: sh*t rolls downhill (and so does water) so I’m sticking with the simple. I don't know exactly which components I’ll use to ensure I don’t sink this ship. I’m certain I’ve picked the worst possible floor option to lay, in sliced pebbles, marble at that. I'm crazy enough to take all the sheets apart, and set each stone individually, because I think it will look better that way.
P.S. 880 lbs of tile, hand loaded into my Tahoe, twice! That should be enough, right there, to cut me a chance.
