Hi George,
I'm in the process of designing my new darkroom and I'm wondering what to do about the sink. I want a stainless steel one but all I find are terribly expensive. Did you buy yours or make it yourself? I'm considering making mine out of wood and just using an epoxy to water-proof it.
Your darkroom looks beautiful by the way!

I ended up with the smallest available "split system" heat pump which serves only the DR. There is no air communication to the outside (no light leaks), as it recycles room air (I have separate outside fresh air by negative pressure exhaust). It is very efficient and effective for both heating and cooling as well as dehumidifying (really, cooling). I cannot recommend these systems highly enough. They are used widely throughout the world and are beginning to replace forced air systems in the U.S. The unit cost for small units sufficient for small rooms is not much more than a stand alone cooling or window-type unit (actually the same as better units, ~$200-$400). The extra cost (either judged to be worth it or necessary) is in the installation, where it pays to obtain someone with experience in split systems.
Hi ROL, I'm in the process of designing my own darkroom and the whole ventilation system is the one I need more help with. Can you specify which split system you have?
Thanks,
Alejandro
Positive pressure: the pressure in the darkroom is greater than the surroundings; air is pushed into the darkroom with a fan; it escapes through a free-flow exhaust and/or cracks and leaks; you need to place an air filter on the fan that blows air into the darkroom, dust exits the darkroom through the exhaust and the cracks and leaks and is blown from the room when you open the door - thus positive pressure is the way to go for a dust-free darkroom.
Negative pressure: the pressure in the darkroom is less than the surroundings; air is drawn from the darkroom with a fan; it enters through a free-flow vent and/or cracks and leaks in the room; you need to place air filters in the intake vent and the the cracks and leaks, however, you can never seal all the cracks and dust gets sucked into the darkroom every time you open the door - in general, negative pressure is a bad idea
David... regarding your EARLY setup. OMG... those were the days. I remember COUNTLESS hours painfully holding my water while trying to concentrate on my printing. But that was when I was just a young lad between the ages of 13 and 18. Later, I didn't have the room in my little apartment and after that the wife (wicked witch of the west) never put up with any of my hobbies but now that I'm alone I have all the room I need and, as Mel Gibson put it, "FREEDOM!!!".
Hey... maybe I'll have the 120 ft2 storage shed plumbed and convert that into a DR. No wicked witch to say "no".
Just got mine done ( middle photo ), about 15 square feet of working space in the storage closet of our 820 square foot 2-bedroom apartment, vertically stacked trays, over 2,000 rolls of film in the fridge / freezer combo to the right. The 16x20 Eco-Wash connects to a diverter valve in our shower. Have been printing for two days and already sold three prints, 10 x 10's from Hassy.
My other darkroom goes over 100 MPH, gets close to 20MPG when not doing those speeds, has 235 watts of solar, a freezer, fridge and lets us stay out in the field for not days but weeks in the same location. I don't print in it yet but do soup film.
So I feel I'm creating a negative pressure environment which is what I don't want.
Any suggestions?
positive pressure system is better ... want to put an exhaust above and real close to the sink ...
