Buying a piece of art is a wonderful and personal thing. Art should be purchased when it catches your eye and it speaks to you. A piece of fine art deserves a place to show it off well, whether it's a painting, a photograph, a sculpture, ceramic, or glassware. Even a fine art print. They all deserve the right spot so you can admire it everyday. However there are places best suited to certain types of art. I'm only going to focus on wall art for now.
1. Near or facing a large window or glazed doors:
2. Over a radiator or heater.
A painting can add a beautiful finishing touch to a bathroom, but again, I would be mindful of the type of art you hang in there. I would avoid watercolours in particular the high moisture environment would not be good for them. I would, in fact avoid any artwork with glazed framing ans the steam can get behind the glass and destroy it. In my opinion the best medium for this would be an oil or acrylic painting which are not usually glazed.
4. Outdoors
These days, our gardens have become an extension of our homes. They give us extra space to enjoy in summer and we love to decorate them as we would inside. However, I would not recommend hanging any piece of fine art out there, no matter what the medium. That said however, why not commission a local artist to create mural, or if you're feeling creative, you could so something yourself with paints suited to the outdoors.
