There must be a reason why electric showers are still a plastic box that has to be installed next to the shower head when a digital mixer can be concealed away.
Does anyone know why? Is it something to do with building regs code? I have tried to google this for a while but to no avail. I was hoping some lovely MNetter may know.
We have a teeny shower cubicle and an electric shower box would take up a lot of room on the wall. We currently have a mixer but this is fitted against the manufacturer's instructions as we have a mains cold water supply to it and a gravity fed hot.
