I don't quite understand the need to drink while I'm in the shower, but apparently the makers of SipCaddy do. They have developed a $14 plastic drink holder that attaches to shower walls or bath tubs with suction cups.
You must have a problem if you can't even take a shower without a can of Bud nearby. OK, maybe I get someone lounging in a bubble bath with some champagne nearby, but do you really need a caddy?
Well, here it is for those who can't live without one.
