How to finish outside corners of tiled shower / plastering corner bead
Just had a builder come in and square the walls of our shower + install new gib. We need to finish the outside corners before the tiler comes in two weeks.
For the right 90° corner, do I just install a corner bead and plaster the outside wall only? I was told not to plaster inside the shower. The tile will be coming up directly to that corner
For the left corner, it's more like 130°. I'm assuming this one I'll just need to use a plaster tape and plaster both sides? This wall comes out to ~1045mm and the shower is 900 x 900. We could tile out to this corner if it'll make the finish easier, but may look a bit strange.
Also, should the ceiling gaps be filled with no more gaps/silicone, or fine to leave as is since it'll be filed by the tile adhesive and covered by the tiles? Tiles in the shower will be floor to ceiling
Tiles are 600 x 600
