    DIY darkroom sink

    For those of you that are handy, this the sink I made and what steps I took. The inside dimensions of the sink is 94 1/2"x25 1/2"

    I started by routing a grove with a 1/4" of pitch from one end to the drain end.

    Here is the drain hole. I used a 3" hole saw bit to drill the hole then routed it deep enough for the fitting and gasket. If I need the strainer that will stick up a little, but I figured I wouldn't be using that too often.

    Here is the drain fitting test fit for depth. I used a 2" shower drain which will have a 1 1/2" line and trap going to the sewer.

    I used deck screws and screwed the sides every 4"

    I routed both sides of the top edges just so it was smoother on the arms.

    The stand with the shelf mounted and my RO water filter for the reef tank which I also use the water for when I develop.

    Nice looking sink, does it take 3 men and an an elephant to move it?

    Haha, no I can actually carry it myself. It's only made from 1 sheet of 3/4" plywood.

    Really nice job.
    Wood is not the first material I would think about when building a sink.
    So you cover the inside with fibreglass?
    Best regards

    Here are mine, built a number of years ago from 1/4" and 1/2" plywood and glassed. Originally two six foot sinks, I cut one down to fit in this smaller room.Click image for larger version.

    You might consider having the "drain end" of the sink placed just a bit lower than the other end - so that liquids (water, rinse water, etc.) can slowly move towards the drain. Does not need to be much of a drop. For my sink (plywood/epoxy, 16ft long X 3ft wide), I've dropped by one inch from non-drain to drain end, which is just enough to allow gravity to drain the sink naturally, without solution levels in trays becoming inconveniently tilted.

    I dropped a 1/4" over the 8' span. If it proves to not be enough I can shim the stand.

    Yes, I decided to use fiberglass instead of the West system.

    Sorry to ask, but what is the West system?
