hey guys, done a few conventional showers, but never one in a basement, on a slab. Any need for a membrane? Heard that you could put thinset down and then deck mud on a slope and then tile directly over that. Correct or incorrect? Didn't see anything in the Liberry on this. Any help would be greatly appreciated. Thanks.

Yes, you still need a membrane in the basement. It should be treated no differently than any other room in the house.

So , use thinset on the slab for adhesion , comb it out and let it dry that way, then pre-slope with deck mud, membrane, and then second layer of deck mud, and then tile , right?

brusu,

Thinset on the slab for adhesion but apply the mud on top of the thinset while it's still wet, don't let it dry. That's how the preslope is built over a slab. Then membrane then final slope. :)

comb that thinset out or trowel it on and smooth it, I assume comb it out. Thanks.

Brusu, comb it, trowel it, brush it, whatever. It's mixed much looser/wetter than normal, more of a slury than anything else. Just get some on the slab then dump your mud onna floor. Roll up your sleeves and start having fun. :)
