Okay, tiling done. Only two bathrooms to go, but that's us ready for when we move in (planning March).
Hex tiles I cut with a diamond grinder. I taped the line I wanted, scored lightly with the grinder right along before then grinding slowly each hex. I used mosaic mats which helped keep them flat nicely. I've got some Ct1 to put round the shower tray and paint two walls, then do a final fit/tighten on everything. This has been quite simply the toughest job of the whole build by far. Looks easy but got to think in 4 dimensions almost, cutting,mixing,laying,grouting ,sealing... We're pretty pleased with it tho.
