How hard is it for a non-professional to use metal trim pieces when setting outer corners with ceramic tile? - or on the top edge of tlle baseboards?
The tile work I've seen locally makes outer corners on ceramic tile by stopping each tile short of the corner and leaving a gap exactly along the corner. The gap is grouted. On a tile baseboard, the top edge of the tile is grouted so the grout slopes from the wall over the top of the tile. To me, it would look better to use bullnose tile or metal trim in those situations.
Bullnose tile is usually expensive and not always available, so I understand why it isn't used. But why isn't metal trim commonly used? Is it tricky or time consuming to install?
If I use metal trim on the outer corner of a baseboard and also on top of the baseboard, how should I fabricate the joint where the 3 pieces of trim meet?
