In a steam iron with a handle, water tank, a steam generating soleplate with ports and a continuous vertical wall enclosing and spaced from an elongated heating element, with steam directing ribs within the wall and a coverplate secured to upstanding bosses to form a steam generating and distributing chamber, an improvement is provided in the chamber construction wherein a plurality of the bosses are disposed along the heating element, preferably as part of the directing ribs, with the bosses being spaced inwardly of the vertical wall to form a straight passage along the wall. The wall has a continuous lip along its upper outer edge forming a cup-like niche for the coverplate with the lip extending well above the coverplate. Generally, the bosses protrude through the coverplate and are staked thereto. A high temperature adhesive sealant is disposed along and over the coverplate periphery at the lip. Preferably, a clearance is provided between the coverplate and the lip so that the sealant flows in the clearance to completely anchor the coverplate to the soleplate at the lip which also prevents overflowing and at the inward bosses with all sealant entirely external to the generating and distributing chamber.
