Summarize this article:

A hookless curtain is slipped over a ceiling shower rod. If you have a more modern style, a hookless curtain can reflect this. They provide a more seamless look and can cut down on cost as you do not have to invest money in shower rings. If your water pressure is very heavy, this can cause the shower curtain to fly away from the bathroom during a shower. To reverse this, consider investing in magnets or weights to hold the curtain down. You can find many weighted shower curtains to suit your needs in a department store or online. If you have a very large shower, you may need an extra wide curtain. This can cost a bit more money but will be worth it as it will more adequately protect your bathroom floor from moisture.  Measure your shower before going out to purchase a shower curtain. This will help you determine whether you need an extra large curtain. You can also use 2 shower curtains for an extra long shower rod and part them in the middle.

Summary:
Try a hookless curtain. Think about weights and magnets. Opt for an extra wide curtain if necessary.
