In a lightweight steam iron with a soleplate and means to selectively deliver water for steam distribution and having a first plastic plate above the soleplate coextensive therewith and a skirt portion around the plastic plate with a second plastic housing having a handle and sealingly supported by the plate whereby the skirt and housing form internal water tank walls and also enclose other iron operating components. A water gauge is supplied for the iron and an improvement on the gauge in this combination includes an entirely integral elongated rectangular niche or cut-out with back, bottom and sides, so the niche forms one of the housing edges parallel to the handle. The niche has spaced apertures in its back side facing outwardly of the iron and connecting with the interior of the tank top. Disposed in the niche is an enclosed integral blow-molded rectangular translucent tubular gauge that is made of the same basic material as the housing material and is nested in the niche against all sides to complete the edge for a symmetrical outer housing surface. The gauge has spaced integrally formed tubes projecting from one side and aligned with the apertures to extend into the tank whereby they are secured such as by heat staking inside the tank to lock the gauge to the housing. The materials are preferably polypropylene and the simple construction forms an integral one-piece water gauge that requires no seals or mastics and the gauge itself is preferably transparent to provide high water level visibility when the iron is either flat or in its vertical storing position.
