External corners for diyer

[davereid]

HiDIYer here doing my first bathroom and tiling project.Firstly just want to say this site has been really helpful, so far and would like to say thanks to all posters.Got an external corner on boxing in for new shower pipework. Decided we want to use mitred/bevelled edges rather than trim. Using ceramic stone effect tiles. I have tried cutting them and ok so far except leaves small defects in glaze but assume this will be covered.Question is, do I put edges flush or leave a couple of mm gap? Plus do I silicon or grout the joint and will this cover the small defects? I will be using silicon for internal corners.Secondly, outside edge of bath protrudes from outside edge of boxing in by about 4mm taking into account adhesive and tile width. Should I line the outside with a 4mm bead of addy, allow to dry, then tile or can I just apply one bead of thick adhesive at once? I'm using bagged addy and substrate is aquapanel.Many thanksDave

What tool are you using to cut the mitre? Yes, a small grout line between joint is best

Hi Blocko

Thanks for reply.

Using a wet tile saw, its got a 45 degree platform on it.

Ok, what blade (sounds petty I know, but makes all the difference)

Any 45 degree mitre cut on a ceramic tile will be much more vulnerable to chipping when cutting and when fitted. I have done them myself, but you need a really good blade & machine in my experience. Have you tried pre-scoring the tile with a dry cutting wheel or scriber to see if that helps?
