Love that idea for the 810 Tom, but don't think that would fly here, the floors are pretty shakey in this balloon framed house...
One thing that I did with my current darkroom (9x12") was building all the walls from 3/4" marine plywood. This means that you never have to look for a stud to attach something - just anchor it anywhere.
Excellent idea! I was going to use that behind the sink, but why not everywhere?
I also put in electrical outlets (4 plug grounded) every linear 48" - and at 5.5 ft height. Never have to have long, tangled power cords dangling everywhere. Used three different circuits too - a spike in power demand never affects the enlarging bulb.
I've got the enlargers on their own line now- will definitely do that again, and was thinking I needed the outlets higher- that's higher than I would have gone but sounds ideal.
I'm ahead of you on the rackes etc. under the sink, and the floor- I'm laying down a rubber floor here- there is concrete on the floor now. Pull wire for overhead lights sounds very nice, I've got a chain now, but the wire works from anywhere along the sink!
usually it is covered by a lid, hinged at the back so when the sink is not in use - it can be folded down and used for loading film-tanks etc. Surface is a thick, lab-type vinyl (I think it is vinyl} that can be cleaned easily. Make a "catch" for it though - had the damned thing falling down one day on my hands!!! Now it is very securely fastened when "up". I need to make a stainless steel "sheet" for the underside of it though. This way it can be used to squeege prints when you pull them out of the wash.
I've got a wash sink in the plan, wide enough for a squeegie board in front of the washer. Was thinking of a centered drain too- and at the developer tray end of the sink, so I'm rinsing prints and washing the sink at the same time. Looking into an air to air heat exchanger for exhausting chems, hoping to save some heating cash over the next few winters. In VT every little bit helps.
This will be my 6th darkroom, #5 is nearly perfect, and I will really miss it unless I get this one 'righter'!
Jan- that is exactly what I did here- worked in the space for about a year drawing on the walls where things should be, then did a reno. Three years later I spent a few days going over all my workflows and did a final reno. This is underway again here before I start building the new space.
