Any business needs a clear welcome sign at the front. This is to ensure that potential clients see that there is a business and also know what it is for. Spa signs need to clearly indicate that this is the company's function on the façade of the building. There should also be opening hours clearly labelled on the door. It can also be helpful to have a window list displaying what treatments are on offer, along with contact details. Inside the spa there should be information and direction signs indicating where to be quiet, whether a massage is in progress and the prohibited use of mobile phones.
