The disclosure describes a commode liner made from a first and a second opposing member defining a top with an opening, a bottom, and a pair of opposing sides. The pair of opposing sides includes a separation distance D, which varies from the top to the bottom, and the distance D is larger at the top than at the bottom. The opposing members can be formed from a latently dispersible barrier composite material including an exposed low strength barrier component, an internal water sensitive layer, and a water permeable, inextensible, water dispersible support layer. When exposed to aqueous conditions on the barrier side, the composite prevents it from passing through to the other layers. When exposed to aqueous conditions on the opposite side, the commode liner readily disperses and may be disposed of by flushing in a toilet, for example. Examples of barrier layers include polylactic acid. Examples of water sensitive layers include polyvinyl alcohol. Examples of support layers include low stretch grades of toilet tissue.
