after years of balancing my enlarger over the hand basin and trays in the bathtub I moved into a new house with a dedicated darkroom... and boy am I happy

I only had one set of taps installed over my sink. I have one of those extendable swing arm taps usually found in laundry's. I have a hose on it as well and have found that pretty much works ok for me. I connect the hose using general garden connectors to either my film tank for washing or my home-brew print washing tray, or use it to wash trays and the sink. It reaches the far end if the sink. I can see an extra set of taps might be useful if the print washer is connected and you want to mix up some chemistry. Currently I unplug the washer, get the water required then plug it back in (not that I do this much, as I usually mix chems before starting the washer)

Regarding your sink arrangements... I would only query what happens in the middle? By having two seperate ones I can imagine the joining walls will get in the way of where you want to put your trays if you want to print large. My sink is 2000mm x 700mm (6 1/2 ft x 2 1/4ft) and covers the whole benchtop. It has 100mm sides (4inches) and at one end it has a deep well( for washing stuff - see attached 'pic&#39. One problem that also has a sort of good side benefit is my bench and the bottom of the well area are all flat (horizontal), so the water doesn't actually run to the drain. The added complication is that since it's made of acrylic sheet, the drain sits a little proud and so, when the print washer is running and the water is running into the well (I sit it in the well) , it fills the well area with (a few mm deep) water before going down the drain. The upside of this is I can rinse my hands easily even though I only have the one tap (although the water has been thru the wash tray) I've contemplated fixing this design flaw but have almost convinced myself it is a feature

Since you mention a Jobo, don't forget power outlets on the wet side. I also have a light bulb over the washing area which has a pull string switch. Other things that I can think of that you might consider are solid mounting points if you're going to wall mount your enlarger.

This topic (darkroom setup) was raised in one of the B&W forums at fairly recently and is worth a read...
