Boiler type - How to Run 4 Showers?

As House Convenor at our local cricket club we are trying to resurrect an old shower room (we need 2 rooms now since the girls have equal rights - good thing too).
The existing CH system only just copes with three existing showers, heating and the toilet hot water demands so we want to put in a new, separate boiler for the new shower room. Question:-
What is the best boiler system to serve a shower room with 3 or 4 showers running at one time?
Anu answers much appreciated,

Use a system boiler (not a combi) Either one with enough instant capacity or a smaller one with a big thermal store timed to come on early when you are going to need showers. Otherwise switch off the store when you want rads only.
Need to cost out the options. Simple big boiler might turn out cheaper and less controls/pipes and no tank.

Are they each going to be used once, or will each be used multiple times in succession? How good do they need to be in terms of flow, e.g. probably don't need drenchers, but is a low/economy flow rate acceptable?
What energy supplies do you currently have? Gas: domestic or larger industrial supply? Electricity: single or 3-phase? current rating?
What is the existing heating system, and what's the boiler model/size?

The showers would be used all at once - we are talking about cricket and hockey teams so probably all showers on for a succession of people, I would guess all showers would need to run for half an hour. Way too long for an electric option.
The current system is a gas boiler feeding a huge hot water tank on the floor below. That system supplies the home team shower room (three showers), provides the central heating to the bar, changing rooms, toilets etc., and provides hot water to the toilets. I do not, off hand, have the capacity of the existing boiler but from what it does already it would seem to have enough on its hands. From memory it is the size of a standard domestic, wall mounted boiler.
When the shower room we are trying to refurbish was last used it pumped water up (electric pump) from the hot water tank below before running it through a blender in to the shower room. It was generally felt to be too much for the whole system - low on water pressure and too quick to empty the water tank below if everything was running at once. This is why we are trying to establish a separate, gas fuelled system for the upstairs shower room.
Cheers,

You are going to need a lot more information about the current system, the capacity of your gas and water services, hot water storage capacity, cold water storage capacity, etc.
You probably need to engage an industrial heating engineer to look at the existing system, see what can be reused if anything, and draw up a specification.
