This type of communication has a very interesting approach. This does not mean that is different from the others advertising models, it’s just a derivative from Outdoor Advertising. The basic concept for Indoor Advertising is to use the restaurant/bar restroom as an advertising environment. Wall posters placed in restroom with chances of being perceived around 60-80% accuracy. This wall poster is usually the size of A3 paper placed in a frame attached to the wall.

This paper size is usually the most used one as a result of economic savings in the company, but the size can be as big as the wall frame is. The communication to the audience is very simple. While the visitor is spending time in the bathroom there is nothing to see, there are just the bathroom walls. Adding poster on the restroom wall (like picture/painting on the wall) the level of comfort is up, plus bigger chances for someone to see it. This means that you have bigger selling power and effective approach in communication with the customer.
