We have always liked the look of Saltillo tile. We like it so much that we put it on the ground floor and upstairs floor of the house. We used the square tiles for the halls and in the bathroom we used the two types of tile that make up the Riviera pattern.
We also like the look of hand cut wood planks. Big wooden planks look great but have problems with splitting and twisting. We chose an engineered wood that gave the same look but without the splitting and twisting issues and with a long wearing surface.
