A shower expander assembly for a shower stall having an access opening includes a flexible plate on a shower curtain. The flexible plate has a flexible line connected to a center portion of the plate. At the opposing end of the flexible line is a ring or loop for hooking over a hook secured to an opposing wall outside of the shower stall. When the ring or loop is pulled away from the access opening and connected to the hook, the shower curtain bows outwardly to increase the usable space in the shower stall.
