How to Turn Old Bathroom Into a Lab

I decided to turn my old bathroom into a electronics lab. Before I build lab, i started to research university laboratories to gather the required information. Then I get some parts and start making.There are some basic steps.

        1.I remove the sink and place a mini desk.
        2.Make a cabinet and place it front of the toilet.
        3.Get some scrap wood and put it over the toilet and screw it to the cabinet.(I don't have enough equipment and money to remove the toilet)
        4.Add some tools and start making etching compartment.
        5. Use old toy to make it.
        6.Finish.
