A shower curtain liner assembly for facile installation on, and removal from, a shower curtain rod includes a panel that has an upper section and a lower section. The upper section is arcuate and defines a channel that is shaped substantially complementarily to a shower curtain rod. The upper section is substantially rigid, while the lower section is flexible and substantially impermeable to water. A plurality of cutouts extends through the upper section from an edge of the upper section to the lower section to define a plurality of hooks. The hooks are configured to couple to the shower curtain rod so that the lower section is selectively positionable in an extended configuration, wherein the lower section is configured to cover an opening of a shower, and a compacted configuration wherein the lower section is configured for a user to enter and exit the shower.
