What do you put on commercial kitchen walls?

Porcelain tiles are a superb choice. As discussed elsewhere in this series of FAQs, the kitchen environment demands ease of maintenance, hygienic functionality, and at least some level of visual appeal. This type of tile is vitreous — meaning it has almost no water absorption — which contributes to easy cleaning and high levels of hygiene. The wide selection of colors, patterns, and styles assure the aesthetics.
