Dear customer, first of all, thank you for your interest. Our product is suitable for use in closed areas, but it does not have an IP certificate for environments where it will be exposed to direct water or intense steam (such as inside a shower cabin). If the socket is in a sheltered area that does not come into direct contact with water (for example, in a high position and where steam does not condense), it can be used. Nevertheless, we recommend using it in dry and ventilated areas for maximum safety. We thank you for your interest and wish you a good day.
