A shaver socket is a type of electrical outlet specifically designed to safely provide power to electric shavers, toothbrushes, and similar low-power devices. It typically includes a built-in isolating transformer to provide electrical isolation for safety.

Shaver sockets usually provide two voltage options: 230V (for European appliances) and 115V (for American appliances). These options are marked on the socket and are available simultaneously, allowing different devices to be plugged in.

Shaver sockets are used in bathrooms because they provide a safe way to use electrical devices in a wet environment. The built-in isolating transformer reduces the risk of electric shock.

Shaver sockets are designed for low-power devices such as electric shavers and toothbrushes. They should not be used for high-power appliances like hair dryers or straighteners, which can overload the socket and pose a safety risk.

While not mandatory, shaver sockets are a common and convenient feature in new bathroom installations. They provide a dedicated outlet for electric shavers and toothbrushes, which is often required by users.
