How to construct a running water basin for developing multiple analog photos

Constructing a dark-room to develop your photos is easy. Buy the materials needed and cover your windows. After developing the photos, you should put them in a running water basin. You can buy an over-priced professional plastic basin, or you can follow this instructable and make your own.

materials for running water basin:

a hose
the plastic thing to attack the hose to your shower
a heat gun or a drill
a mask for fumes
a pen and a measuring tape
a saw to cut metal sticks in two pieces
the biggest plastic box (snalis) from ikea
4 to 8 alluminium sticks to hang drapes from ikea
(I used 4 pieces cut into half to develop 2 photos, you can use 8 to develop 4 photos)

Step 1 Prepare material, measure the box

Cut the sticks into half.
Cut your hose to desired length. It should be long enough to connect the base of your basin to the water source of your shower, and a little bit longer.
Measure your plastic box.

On the small side draw a vertical line in the middle.

Measure your photographic paper, draw a horizontal line shorter than the height of your paper, through all the sides. Draw another horizontal line just under the first one, the sticks will fit in between these two lines.

Draw another couple of horizontal lines near the base of the box. Here we'll put the sticks to hold the base of your photos.

On both small sides, draw 4 vertical lines on the left, 4 vertical lines on the right side of your first vertical line in the middle. The distance of the lines should be the same on both sides.

The distance between each couple of lines should be enough to put the paper between, but not too big that they fall from the sides.
(2 lines to fit the stick in, 1 cm space, another 2 lines to fit the stick in)

If you want to wash four photos at the same time, you should draw 8 vertical lines on each side.
