wetroom tanking walls and floors - Tile Advice

[hmtiling]

Been seeing a few tilers posting wetrooms on twitter with no wall tanking. I've always tanked anything deemed to be a wet area, whether wall or floor, in a wetroom and wondering where the rest of you stand.
Twitter is a bit back slappy imo, with nobody telling anybody they're doing it wrong when they clearly are. I think people should be told, otherwise, how will they learn?

Oooh! You're brave if you publicly criticise anyone on social media!
Snowflakes everywhere with sensitive feelings!

Yes - I would always tank a wet area.
The sole exceptions would be if I fit out with Kerdi-board (so not needed)
or using very large format in domestics with zero, or one grout joint in which case I would tank floor/tray union and up the wall 12". (lazy I know!)

Someone posted a geo job on twitter with an obvious mistake and I couldn't help myself.
I can't believe a geo 'specialist' would make that mistake, let alone post it.
The snowflakes need telling Mark!

I'm with you all on this one too. I have seen this also! Consecutive wet room jobs by the same tiler where they have not tanked the walls.

If it's a moisture sensitive background it should be tanked, end of!!

It's a bit "wavy-davey" down the left border too!

And that rear mountain bike tyre looks to only have 23 psi in, 24 at the most!

I'd have taken that weed out for the sake of the shot.

Not bad......not great but not bad, he missed a black triangular piece out.
