Most waffle shower curtains are about 72 inches wide. Common heights are 72 inches or 75 inches, and some listings show other sizes such as 72 x 70 inches.
Waffle shower curtains commonly appear in polyester and polyester blends, cotton blends, recycled polyester blends, and in clear waterproof PEVA (polyethylene vinyl acetate) for liners.
They come with buttonhole-style tops, ring-top (hook) options, and hookless designs that use grommets so the curtain slides directly onto the rod.
Fabric waffle curtains are generally machine washable (follow label instructions — e.g., machine wash and tumble dry or machine wash cold, tumble dry low). Clear PEVA liners are typically spot- or wipe-clean only and should be line-dried or laid flat to dry.
Listings describe true waffle weave or waffle-knit surfaces and waffle-textured finishes, as well as dobby or other woven constructions that produce a subtle textured look.
Clear PEVA waffle-style curtains are described as waterproof and help prevent splashing onto the floor. Fabric waffle curtains typically rely on a snap-in or separate waterproof liner for inside-the-shower protection.
