A housing for a drying device which can be folded in and folded out comprises a base which is situated on the rear side and can be attached to a vertical support, such as a wall, and with respect to which the drying device can be folded in to form an elongate unit, wing means which are suspended on the base and can be pivoted along a pivot axis directed in the longitudinal direction of the unit between a closed position for covering the folded drying device and an open position in which the drying device can be folded in and out, as well as supporting means for supporting the drying device with respect to the housing. The wing means, in the closed position, extend forwards with respect to the base.
