This light weight plastic liner fits right on to the same hooks as the shower curtain.  It hangs just inside the shower and protects the curtain which hangs on the outside of the shower lip.  Also it is long enough and wide enough to keep the floor and the wall completely dry.  It was a fun day shopping for all of this without leaving the house and an even more exciting day when my on-line purchases arrived.  I highly recommend to all my friends to go to Joss & Main and leave the leg work to you so they can enjoy the results.
