Bill of materials (BOM)

For the base structure:

Ikea Nissafors: A similar tray would do. But we chose this one for the ease of adjusting its height, its size fitting nicely with the plastic washbasin tray.
2 x containers to store water: One for clean and one for dirty water: We used these from IKEA for convenience of getting all materials from the same store. Any bucket that fits would do the job. We'd suggest to use at least 5 liters for less frequent refilling.
3/3.5/4 mm x 10/15mm screws with nuts: You'd need just 3 set of screws and nuts.
Plastic tray from Ikea: Feel free to use the colour combination you like.

For running water:

DC pump (5V)
1m of hose in adequate size for the pump you purchase, can be found in local hardware or aquiarium stores
Cloth mesh to filter out solid particles - We used a surgical cap for this: Cheap and does the job to perfection.

For the Switch Box

Illuminated Pushbutton: We used a button like this one, but purchased it from the local electronics shop instead. Would suggest you to do the same.
USB-C adapter: One of these did the job for us. If you have any existing USB adapter, you can use it.
Small size Tupperbox to use as a switchbox. (alternatively you can 3d print the switch box using the files we provide)

For the Faucet

A water toy that can be converted to a faucet: You can be creative to use any toy that can resemble or function as a faucet. The only criteria is that it needs to guide the hose from the pump into the washbasin. We used one of these toys that we had at home.
