We spotted this sweet little detail in the bathroom of friend of ours who lives with a rented bathroom that's awaiting a facelift sometime down the road. We actually like this idea of using a stair spindle or some other makeshift leg to visually support a floating sink.
You could find countless rustic elements to use as faux sink legs at salvage shops like Restoration Resources in Boston's South End. In the case of our friend's bathroom, we like the warm natural element that this wood leg adds to a bathroom that otherwise needs some TLC.
