Thanks for the input Jonathan. So you put together your own light baffling
chamber and 3rd party fan/s to make this? I'd love to see photos of that setup.
I've decided not to decide about my flooring for now as just getting IN THERE
is the biggest hurdle. Plumbing has gotten ugly and we're bringing in the big
guns to deal w/it while we try to finish the construction and somehow fit in
the drywall guy in between our days in there. City of Chicago has for 2 weeks
straight not picked up our trash prompting calls to the alderman's office where
they have had to arrange a special pickup. No idea what's up with that.
New fridge doesn't fit, bathroom needs to be redone, etc ad infinitum...Welcome
to home ownership right?

I use a multispeed exhaust fan that draws
air directly across my sinks into a slotted plenum chamber. The fan draws about
1500 CFM at maximum speed, and produces about 50 to 75 FPM (feet per minute)
air velocity across the sink top towards the slot. So far I have not had a
problem using Poly Sulfide toner in an open tray.
The air enters from a slotted soffit where
the ceiling meets the wall opposite the sink. The Dark room is 10’ wide
between the sink slot and back wall. The length of the dark room is 20’.
The low air flow of 200 CFM is handled by a smaller fan in the same exhaust
system. The air intake has a 24”x 24” fine dust filters installed
in the air path. The darkroom is on the second story therefore the exhaust
stack containing the fans is on the roof, as is the air inlet. They are located
far enough apart and designed to prevent contamination of the inlet air.
I had considered other lab venting systems
such a hoods etc.
I used a roll of Congolium floor covering
laid with adhesive on particle board. This was used to provide a smooth surface
and so that the floor covering could be removed at a later date. I made a
pattern of the floor perimeter with Kraft paper. I precut the roll of flooring
before hand allowing for a rolled edge along the perimeter where the floor met
the wall. Installation went very quickly with two people. I use runners of anti
fatigue mat in front of the 15’ of sink, and counters.

That's why I had mentioned that as presently I tone
outside the darkroom, but in the new digs, (such a disaster down there
presently!) I'll have to do that outside the darkroom itself I guess as well.
Was hoping someone had magic formula (there's always thiourea based sepia
Eric) of ventilating that works. I plan to take wet prints to a screen
dryer outside the darkroom as that creates too much wind from the fan.
There's already a floor down although a plumber today
offered to dig some of it up to put in a pit (for a possible bathroom) to
guarantee against backup. I may just go up 2 flights to avoid that
although now would be the time to commit to doing it...ack, can't decide!
My darkroom presently was made to be a bedroom, print washing and toning and
drying area was a
kitchen. Digital area and print spotting area was a living room. It will
revert back to those uses after I leave this month and some considerable rehab
is done.

In reference to toning: If possible do not do it in the darkroom
or where sensitive materials are stored. The gasses emmited by sulfiding toners
are fogging agents and are quite toxic as well as being unpleasant.
The usual recommendation is to have separat dry and wet rooms but
there may not be room. If possible the darkroom should have a wet and dry side.
If possible have a laundry type tub as well as a regular darkroom
type sink. The tub is very useful for washing trays, etc, and can also be
useful in other ways. It does not have to be large and can have a removable
duck board over it for more tray or tank space.
If you use an "archival" type print washer make sure
you have a place for it that will support the weight and allow it to drain when
overflowing.
See if its possible to have a floor drain. If concrete is already
poured this is probably not practical but if a new floor is going down ask
about what it would cost. It will make cleaning easier and prevent flooding.
I am still doing with a darkroom that masquerades as a kitchen
most of the time.
