re: Need help, I’m retiling my bathroom

I just finished tearing out the walls in a small bathroom--82-year-old house.
The shower was tiled to about 7 feet and rest of walls about 4 + a wall enclosing the shower.
Walls were 3 inches thick. and yes, that's wire mesh and concrete and mortar. much better to get to the studs and pull entire wall off in chunks. I used an angle grinder with diamond blade + a Dremel Sawmax w tile cutting blade + sawzall with carbide + wire cutters, to get started and to make manageable pieces (some pieces were over 200lbs).
For the floor tile, i'm using Bosch RH228VC (I just ordered for shipping tomorrow for free-gotta get my $ worth of the now-more-expensive-Prime).
have fun. back-breaking work. i had to rip mine out or else i would've just tiled over it. It did open a lot of room though--gaining nearly 3" on each wall + one wall has 6" studs, so i'm doing some cool recessed shelving + bench in shower.

that's concrete, good job ruining the base of your house, send pics when it collapses.

Can’t be concrete can it, it’s an elevated house?

Making progress (I think)
Posted on 5/12/18 at 8:34 pm to DavidTheGnome
also just a tip for later on, if youre using large format tiles I highly recommend a tile leveling system

Just dig out a 7’ x 36” hole and put a door there.

Thanks I do plan on large tiles. There is some kind of wire mesh underneath the cement/mud, am I supposed to be pulling that up? Is my goal to get down to the wood?
Posted on 5/12/18 at 8:41 pm to DavidTheGnome
You gonna need some of this.

While I used to set tile professionally, this should not be considered professional advice since I haven't been to your house.
What you are taking up is mosaic tile most likely set in a fresh mortar bed. The way they used to do this was to install the metal lathe (wire underneath the mortar) tacked to the subfloor, then screed in the level dry pack mortar bed. As it was curing, the tile setter (prolly some small Italian dude) would work from kneeling boards and spread and dampen portland cement on top of the curing mortar and set the tiles directly into that. The whole system would cure together and it was VERY EFFECTIVE (as you noted the tiles stuck wonderfully).
Later, with the onset of "Thin set" mortars, they began to screed the mortar bed and let it set, coming back the next day to set the tile (using the thin set). This works well but you can chip these tiles up without damaging the mortar underneath by removing the grout and attacking them from the side. The thinset has good adhesion properties but can fail in lateral sheer.
Now, given you have removed your dry pack mortar bed, it must be replaced with something. Whatever you do must be the same thickness (or near based on the thickness of the replacement tiles) as the old bed as the base tiles of the walls should be at the elevation that works with the floor tile thickness you will be installing. Best would be to go back in with dry pack mortar. In fact this is the only thing I would do. I cannot imagine that you would be able to "sandwich" enough wood layers (or otherwise) to get to the correct elevation (with precision).
You are going to need to remove your toilet, as your new tiles should go under it. Whatever you do around the toilet will have to be very sturdy as the toilet should not rock or move which will cause a leak.
Based on what I have seen in this thread DO NOT frick WITH YOUR SHOWER ENCLOSURE. You have no chance of it not leaking when you are through. Thakfully for you this appears to be the bathroom floor but not in a "wet area" like the shower which would require a water barrier like a "Pan" or one of the newer roll on applications. Good luck, there are videos on youtube.
here is one that shows hom to mix the mortar.
You need to watch this plus a bunch more.
I can answer specific questions if you have more.
ETA: This dude looks like an experience tile setter showing you how to install the dry pack mud floor
He is installing a shower floor which must slope to the drain. Yours thankfully, should be level. The way he mixed the mud is exactly how we used to (except we did not use quickcrete (but you can).

Jesus is the only one that’s going to be able to save DtG’s arse.
OP, I have been scouring that other website looking for this post and haven’t seen it. What gives?

Awesome thanks for the great response. Is pouring a new mortar bed fairly straightforward? Toilet and sink is going to be removed and I’m not going to mess with the tub. Once I get it cleaned up I’ll post back with a "now what" post.
Thanks again
Thanks again

That green tile on the mud bed looks like it would have outlasted all of us and then some. Grout was probably getting a little tired.

Watch that 2nd link I posted. You would need to install roofing felt over your subfloor (to hold in the mud than metal lathe tacked to the subfloor (to control cracking). That is not shown in that video because it is a shower install inside a shower pan.
Good luck. It can be done.

Strip down to the subfloor, then install Hardi board throughout. Thinset, tile, grout- done. You dont need to glue or thinset the Hardie down to the subfloor, just use a high quality thinset when installing the tile. Depending on the initial install, you may have a height difference from your hardwood (or other existing) floor to the new tile. Add a transition piece and you're good to go.

You are telling him to install a floating floor in a 2" depression that will leave gaps under his cove base and not be stable for his toilet. Do not listen to this guy.

We had this concrete-like backer board installed under our tile in the bathrooms.
Have y'all discussed this yet?

Question though, the links you posted seemed geared to showers. This isn’t in the shower, it’s just the floor of the bathroom. Same concept though?
