Use PVC pipe and plastic tie straps Keep your razor from falling into the tub with this simple holder. Cut a 3-in. length of 1-in. PVC pipe with a handsaw. Cut two 1/8-in.-wide notches in the pipe. Strap the pipe to your wire shower caddy with two plastic tie straps hooked in the notches. Drop the razor into the pipe; the blade will catch on the edges of the pipe, keeping the razor off the floor.
