All bags are waterproof, so you can shower and go swimming with them. My ostomy is low enough that I can wear a two piece bathing suit. I have one that's a tankini top with a skirt bottom and another that's a bikini top with board shorts. I also have a one piece with a skirt that's black with a halter top.
I live in Florida and go to the beach almost every weekend, so I'm glad to be able to wear a variety of different suits. Where in Florida will you be vacationing? I live on the Southwest coast near Sanibel Island, which is where I work and go to the beach on the weekends.
Dx'd Crohn's in '99 at 28. Proctocolectomy and ileostomy in '06.
Disease-free, medicine-free, and very thankful to be healthy again :)
