I'm a big fan of galvanised tin baths. Not obviously, as baths. That would be silly. Next thing you know I'd be recommending you use pipe cleaners to clean pipes. But no, as a large ice-filled drinks cooler at a 1920s themed speakeasy party, or as a garden planter, they are perfect. In fact I've used mine for both (not simultaneously you understand).
I picked up the bath for about £30 at an antique shop, but you can also find them online. Although not cheap, they are pretty good value when you compare them to similarly large containers.
