How would you finish this without trim

[malawhap]

As you can see the wall runs out and i have to finish this without trim, and there will be no tiles on the other side of this wall .So once i rip these tiles off how should i finish this wall .

you could try rounding off the grout, make a profile with abit of hardboard and run it up the corner over the grout, but unless you use trim whatever you do is going to look rubbish i think

can you skim , if you can keep your tile stright down the siad of the wall using your level you'll have lips running over the wall thats running out then just skim the wall flush with your tiles , if you can't skim put your cuts facing the shower wall keeping the nice edge of the tile as close to the uneven wall edge as poss , otherwise bit the bullet and use some trim

I have rounded off grout in the past, then painted it and it looked just fine.
