Here's what you'll need:
• A stainless steel basket. I found mine at Target for around $12. I got a second smaller one from the kitchen aisle to hold my soap and razor, though I haven't installed it yet.
• Electric conduit strap (like this)
• Speed nuts (like this)
• Small machine screws and nuts
(Total cost: About $15)
Here's how to do it:
• Attach the speed nuts (which are like little clips) onto the basket at a width that matches your conduit hanger. You'll need pliers to pry them slightly apart and to clamp them back together once around the wire.
• On one side only, line up conduit hanger with speed nut and affix with machine screw and nut.
• Wrap around shower riser, and line other side into the speed nut, then affix with machine screw and nut. It should something look like this from behind (photo by Caitlin):
(Total time: About one hour, but I'm inept with tools)
I only used one strap on my caddy, and because my shower riser is so thin, I wrapped kitchen twine around the riser to act as a stopper for the strap (there must be a better way, but I haven't found it yet). The caddy tilts forward ever so slightly, but is completely sturdy and looks really stylish. OK, not as stylish as these awesome ones at Ace Hotel, but it's an easy and cheap solution if you have a riser shower without a wall to support a suction-mounted caddy.
