Change rooms in factories ... if used for just that ... as a place to have a shower and change and store a couple items in a locker ... its pretty straight forward ... throw in a table ... a couple chairs ...a kettle ... a microwave and a fridge and an extension cord to power everything ... still pretty simple ... find a small DB in the room which already supplies a geyser and the lights ... add a plug socket and try close off the shower area to createa a seperate room ... apparently its gets a little more complicated than just a few SANS elecrical regs ... time to call a friend and book in to the CYA club
