Do you install tile or hardwood first?

I have done this and I always have the hardwood installed first. Then I install the ceramic tile. To protect the hardwood floor from getting grout or glue on it I cover the hardwood floor with a soft cover (to prevent scratches) and tape it down. Then place a plastic cover over the hardwood. Then I can install the ceramic tile at the edge of the hardwood creating hardly or no seem and level with the hardwood. When its done it looks beautiful.

I would install the tile first , that way you don't risk getting glue or grout on your hardwood.
