I am looking for trim for plain white bathroom tile. Can this be bought online? For instance, a 6" rope-pattern edge at Home Depot is $2 each. Are there other places to find this? Searching online always leads me to flooring.
I would try a tile wholesale shop. They buy in bulk and pass savings on to you. You can also find discontinued tile for dirt cheap and if its a small area you can buy enough plus 10% extra for replacement later. Just keep shopping.
