It's best to wait at least 8 hours after getting a spray tan before taking a shower or getting wet. This allows the tanning solution to fully develop and bond with your skin.

Some tanning solutions may require a longer wait time, so it's important to follow the specific instructions provided by the salon or the spray tan product manufacturer. It's also important to avoid any activities that may cause sweating or rubbing of the skin before the recommended wait time has passed, as this can affect the outcome of the tan.
