I bought some Aqua Guard on drugstore.com. It is WONDERFUL!! I usuall put it on and then use waterproof tape to re-enforce the edges to make sure water stays out. It comes in different sizes, 7 X 7 seems to work best for me. My port is located under my left breast, so plastic wrap isn't really and option. The Aqua Guard comes only around the dressing and I can wash the rest of my body. It cost $10.99 for 5 but well worth the money as far as I am concerned.
