I currently have a gainsbrough 10.8kw electric shower, but I have always been unhappy about its outflow. Is there a way to boost the cold water pressure to the shower or perhaps there is an off the shelf electric " boosted " shower out there.
I'd love to have a power shower, but the family gets too many showers to be practical to run one.
Any help or suggestions gratefully received..

Yes. However, the more cold water you force through the shower the less hot the water that comes out of it will be, assuming that you already have it on the maximum heat setting.
There are a number of solutions to this, but all involve varying amounts of work and variable results.
You may be able to boost it - however, the way these showers work is that the water temperature is governed by the flow rate. When you increase the temperature, you're just slowing the water down, allowing the element to come into contact with the water for longer, heating it more. Therefore by increasing the pressure, surely you're also increasing the flow rate, which would reduce the amount of time the water is in contact with the element, causing the water temperature to fall.
If you're after a more powerful but cooler shower, it might work. I've no idea whether you can actually pump mains pressure water anyway.

I believe that there are electrically heated power showers available. Alternatively even the smallest single impellor shower pump will work, provided that you have a gravity tank feed available. You must not pump mains cold water.
Of course, if your problem is that the electric shower can't get a decent enough flow rate when on full heat, then this won't be solved by a pump.

Unless your mains pressure is below minimum spec - which is a dribble - the shower is already reducing the flow to maintain temperature.
More flow needs more power. A simpler approach would be an aerator, which will make it feel like the flow is more. Another option that would work is to use a drain heat exchanger, this will increase the heat/flow ratio of the existing shower. Both these will improve things.
Or if youre wiling to throw serious money at it, how bout a 27kW 3 phase electric shower.
And if youre not willing to spend anything, try a friend's 3kW shower, and develop some gratitude.
