To save money, many people buy cheap plastic shower liners. It’s true that these usually cost significantly less than washable fabric liners; but it may not be the best move for you in the long run.
Over time, everyone’s shower curtain liner starts to get moldy. It’s an unavoidable result in such a wet environment.
If you’ve got a plastic liner, you either have to take it down and scrub the mold off by hand, or you have to throw it away entirely and replace it. This will quickly become either a huge waste of time or money.
Although they are a little more expensive at first, fabric shower liners quickly pay for themselves. At the first sign of mold, all you have to do is take it off and pop it in the washer with the rest of your whites. So much easier!
