If you are looking for ways to make a better looking drain for your tub or shower, I found something that may interest you.  Most drains in your bathroom or round and the tile is square ,this causes more work for the tile person and if you  could find a more aesthetic alternative for the round drain most people what would invest a little more time and money to do so. I came across this video from slow homes talking about 2 types of drains that solve the round drain dilemma.      It is nice to see that some of the most mundane things can take on a new look and still function the same or even better with creative application.
