We always see 1" tiles in magazine pictures. However, pre-Great Depression, 2" tiles could be had. There are a few companies out there that offer a 2" tile, but there are a more costly option. And some people not familiar with them might think they look a little "off." But really, there are quite lovely.
Look at the "bath rug" made of tile. Adorable!
A little more subtle design.
Now, I should mention that hex tiles were not the only game in town back then... in some parts of the country, instead of hex, they used a penny round. A penny round is the same as a hex tile, basically, just round instead of geometric. Just round little dots attached to a backing sheet. And, of course, they came in a 1" size, too.
Cobalt blue for the daring!
If I had the time and money, I would have done this Ann Sacks tile instead of the hardwood floor in my master bath. Isn't it gorgeous and beachy?
Penny rounds on the wall? Not traditional, but I like a little weird. The Vermeulen's bathroom posted on Apartment Therapy.
