I am wanting to put four showers in the changing room of my sports hall. But am confused on how to plumb and wire them in. Could someone advise me on the easiest way to do this ?

Be more specific. Is that going to be 4 separate shower stalls ( or rooms ) or 4 showers in one big room sharing the same drain? Also, what does the "wiring" pertains to ?

I'm going to guess that you are talking about putting in ELECTRIC SHOWERS. If this is the case, AND you are some kind of commercial establishment then I would STRONGLY advise you to hire an electrician and a plumber for this job!

If you make even one mistake here, it could kill someone! Hire the right people and make sure they get the proper permits for the job. This will lead to a safe job and eliminate any real liability for you!
