Could easily be made with hollow box uprights, run the water tube through one and the top hollow box with a PVC tube that you drill holes in for the water to run out. Faux paint it to look like copper, really pretty easy.
Separate your wall colors. This is SUCH a good idea!! I dont like two colors coming together on a corner and this is the fix for that! This would also be a great fix for the beat-up corners in the house. Such a good fix for older homes!
