The invention relates to a device for generating steam. The device comprises a water outlet arrangement having an open end to spray water onto a water receiving arrangement. The water receiving arrangement comprises an interior surface defining a chamber in which the open end is arranged so that water sprayed from the open end is sprayed onto the interior surface. The device further comprises a heating element for heating the interior surface up to a temperature for generating steam from water sprayed on the interior surface. The interior surface is formed by two separate cavities, the open end comprising a spray nozzle received within each cavity so that each spray nozzle sprays water onto a region of the interior surface, each region being defined by the cavity in which a respective spray nozzle is received. This allows the water sprayed by the water outlet arrangement be more uniformly spread on the interior surface, leading to more effective heating and more steam may be generated per unit time.
