The tiling is looking really good, can't wait to see the finished result. I'm a big fan of hexagon tiles and certainly want to use them when we redo the bathrooms and en-suites.
In all likelihood you won't have any issues, but that's more down to the adhesive, grout and the quality of their application.
Belt and braces approach would be to use a tanking membrane in the shower area and cement type boards elsewhere.

Moisture resistant is better than nothing, but still they're only resistnat, not waterproof.Cheers
They're moisture resistant boards, tanked to 1300mm along the left wall and just beyond the glass shower screen on the back wall.
Didn't consider this not being enough?
Guess it's a bit late now anyway!

No, that is moisture resistant plasterboard, how on earth is it "fully waterproof"? Especially where there are drywall screw penetrations through the moisture resistant layerThe boards are fully waterproof. Things have changed.
