simplehumanST1018 237ml Automatic Hand Motion Liquid Soap Dispenser, Volume Control, White Plastic

Can I use this as a toilet?

Does any liquid DISH soap work or do you have to use recommended brands? I have never used 'method soap' so I do not know if it is hand or dish soap. Thank you.

What are the construction materials for all three of the major pieces, including the top, the front panel, and the rear soap container. In particular, please specify if the metal-looking parts on the bushed aluminum are true brushed aluminum or are another material with a brushed-aluminum look.

Can you use foaming hand soap with this touch less dispenser?
