Some kind of basin that drains into a 5 gallon tank would be handy for a darkroom-
Cheap(ish) containers are 5 litre water bottles, especially if you happen to use bottled water anyway-
They’re useful as a water supply, and for storing re-usable chemicals- Hypo, fixer, etc…
Update: project stalled for foreseeable present. For now I am currently focussing my efforts on adapting a smaller, make-shift space (bathroom, minus bath).
Hi Damien.
The bathroom may be a more suitable space than the bedroom. I used to use a small bedroom to process b&w and colour many years ago. Dust was a major consideration. The bathroom would be less likely to have this problem ie wall tiles don’t tend to hold much dust & the flooring is probably more suitable.
