One of the stranger requests I have had recently, customer wanted me to design and build a shower area for them to clean their dogs off, after they had been for long muddy walks.
I built a frame for a largish shower tray, plumbed in the pipework for a small shower and then tiled the whole area. I think the finished article looks really good, the intention is to put some hanging baskets underneath for old towels etc to be stored in.
