Many people enjoy a soak in the tub as a way to unwind, while some prefer to relax with a glass of wine. So why not indulge in both at the same time? This suction cupholder firmly sticks to the side of the shower or tub providing a sturdy place to rest your glass while you bask in your at-home spa experience. The cupholder can also work for cans, coffee cups, or shampoo bottles (if that's what you really want to use it for). Available on Amazon; $13.95.
