The Impossible Darkroom - How realistic is it to plan this and build it

 

I've missed out on having a full darkroom a bunch of times.  The closest was just over 20 years ago and it was without running water.  I now have a tiny space and this is the design I came up with.  Having a tight 7 foot by 6.5 foot space to work around, it is further hampered by pipes and household wiring running all around above.  The dry side wall will host a set of shelves on the back for storage.  The wet side is all flag stone and will require a very fancy wall stud installation to get the most use from that side.  The custom epoxy coated sink will be one of the most complex builds.  Another issue is the manner the drainage works and if I can legally put chemicals down this type of drain.  I can tap near by water lines and will have to improvise a water temperature control unit to save money.  The entry side is simply a heavy curtain in a light trap channel, however, the opposite wall is also flagstone and pipes run along it as well a meter.  An access hatch must also be kept clear and to make things more interesting, the space is invaded by spiders.

Although I have not compiled a cut list or decided on types of materials, it is easy to see that this will not be under my $100 limit for supplies.  The primary part of the project is the wet side.  An existing temporary dry side stands now.

Sink portion will require over 2 dozen pieces to form.

The sink is a composite of pine boards to keep the cost low, the real money is the epoxy resin coat to waterproof it all.  Outside dimensions are 7 foot by 2 foot and with a 6 inch high rim.  The base will not be easy as it has to have a mid-board to hide the pipes as well a valve to capture chemicals to a separate container.  The back well will depend on actual vertical space available as well as the clearance of a set of sewage pipes that run across the entire space above.  The issue of light trapping the above plumbing will be a mosaic of plastic sheets and shields to block light leaks.  Also needed is a path for the air duct to drain off the fumes as well a fresh air vent.  

The existing dry side will be modified, if possible, adding light tight drawers and storage for accessories.  The enlarger table will be reinforced to hold the weight of the Beseler 45 MCRX and its dichroic head as well as the extra space below to house the expanse of film holders I've collected over the years.    When complete, this setup should be capable of handling 20X24 as well color processing.
