If you want an affordable Bluetooth speaker for the show, IKEA offers a new VAPPEBY portable speaker. It doesn't appear on IKEA Canada's website yet, but it retails for USD 15 (around CAD 20). This silicone-coated speaker is just a three-inch square that's two inches thick. It comes with a lanyard-style cord, so it's easy to carry around or hang in the shower. You can get it in yellow, black or red. It can work as a stereo pair if you buy a couple of these speakers. And most importantly, it's IP67 rated for water and dust resistance.
