First created to adorn the walls of the first subway station in New York City in 1904, these simple rectangular tiles showcased simple colors and a sleek finish. Over a century later, subway tiles have become a staple in interior design, showing up in kitchens and bathrooms.

The Signature collection by PORCELANOSA represents the character of traditional handmade ceramics. The pieces of this collection have an irregular format and a surface that is not completely flat, so when light reflects on them it creates various streaks.
