What is a reasonable length of time for a shower?

Yeah, what is it with English showers? The worst shower I ever had in my life was in an apartment in Eaton. The water pressure was barely enough for the water to make it up to the shower head, where it then dribbled out. Are the pipes in England so old they have to dial down the pressure to keep them from rupturing?
