It depends on the rest of your load. If you have a cooker and a kettle/toaster which will be used at the same time as two 9kw showers you will exceed 100amps, and the service fuse will melt. If you can stagger the use of the showers you could have, in theory five, but there's no way you could use more than two at any one time.

The answer depends on two things - 1) what voltage is your electricity supply? 2) what kW rating is your shower?
Assuming the former is UK 240 volts then using the formula W = V x A (Where W = Watts, V = Volts, A = Amps) then you have potentially 24,000 amps available (or 24 kW)
Picking a totally random electric shower....

this is 10.4 kw - so you could in theory use 2

Your given data of 100A is not enough for design purposes. Different requirement in different kind of scenario. Maybe you need to ellaborate more on where you want to apply the shower (yes is definitely in the toilet but in the office building? Domitory? Hospital ?? etc)
You also need to study in to the occupancy and choose the best shower (heat?? or pump??) for your case. There are many product in the market. If you are using the portable type, this could be around 100W - 250W. If you are using the centralized type, this could be around 1kw to 5kw. If you are using the solar heater type, then could be 1 to 10kw. Again, this depending on how gigantic is the shower heater you want to design.

9kW shower = 9000/230 = 39 and a bit amps.
100Amps/39 = 2.5
So you can have 2, 9kW showers.
Be careful though, most modern houses have 80 Amps older houses have 60 Amp supply.

1 you must first check incoming supply is adequate especially checkout the existing fuse box,and current rating of main switch.Shower are 45 Amp,32 Amp

You will be having your last shower if you shower with 100 amps.

Depends on the power rating of the shower. 100A can take a total of 24000 Watts at 240Volts. That can be made from 2 12000W or 24 x 1000W (doesn't matter) showers as long as you don't exceed the total of 24000W. Check the cables as they need to be up to the job.

That depends on the amps used per shower. If you don't use hot water, then you'll get more showers. If you have a more powerful pump (higher water pressure), you'll get fewer showers.

As many as you want as long as only one is used at a time

I would think a maximum of two would be safe, if they are being used at the same time.
