I am in the middle of a bathroom renovation and order several tile samples in a gray hue.  All the samples were generous sized and the tiles were very high quality.  If you are ordering tile from the internet I strongly recommend ordering samples first if the color hue is critical to your design scheme.  I was looking for a tile in more of a silver blue grey color (cool) and this tiles were all a true gray color (warm).  I did find one tile that I was really interested in, but by time I received the sample, the tile was already sold out, so it is really tricky ordering tile from Wayfair.  If you can view the tile at a local tile store, than order immediately from Wayfair you are more likely to receive your purchase before it is sold out. 

Pros: Nice quality, price
Cons: samples arrive too late to order
