Vinyl stickers are perfect to put up in wet areas, as water will run off them. (Vinyl stickers are what car stickers are made of)
They come on a backing sheet so if you do not wish to use them as a sticker simply leave on the backing sheet. We use a good quality vinyl that will not leave self-adhesive residual.
