Hello! I want to tile the space between the washbasin and mirror in the bathroom myself (as a splash guard). I still have tiles left over from the shower and would like to use them. Unfortunately, they are "difficult" tiles. They are Equipe Ceramica Lanze tiles, each with one pointed side. Kind of like an arrow in two directions. I have to cut off the point to get a straight wall edge. That only works moderately accurately. Something always goes wrong.
How can I nicely finish a tiled wall at the bottom edge? The cover strips available for tiles are only suitable for the top edge. There is no mirrored version. 
There are tile edge strips that you can use on the top, bottom, and sides. 
If cutting tiles with a tile cutter doesn't work, I would try using an angle grinder.
