Showers in England

Hi.  This may seem trivial, but I've heard and read online that bathroom showers in England often have low water pressure, and that a special contraption needs to be installed to have what are called, "power-showers," which are showers that have good pressure like those in the US.  My question is: why are showers with good pressure so difficult to install in England?  In the US, every old house or other dwelling can easily be retrofitted if necessary with good water pressure for a shower with relative ease.  What's the problem in England with spreading this (seemingly) simple technology?

Cost to the environment David, they apparently used much more water and tend not to be installed any longer.

david, the best shower is in downing street.

Tut James don't you mean the WORST shower? Lol

My understanding is that showers are not only faster and cleaner but use less water than baths.  I can't imagine living without a good shower!

I agree David, except for the Power Showers to which you refer. They are heavy on water.

Yes, so why can't they make the showers like they do in the US, which just have good pressure without the contraption needed for the power shower.  I just mentioned that because it seemed like that was the only solution possible in the UK.  Is it that water mains are holding less pressure or something?

They are manufactured and available here David. Often work off of a cold water mains supply heated through element/coil. But I seem to remember the power showers consuming something like 20 times more water to what we use today.

Good--so I can move to England and possibly get a good shower!  Yay!

Trust me David, we really have got the biggest shower over here! Ask Michael (Lancashirelove) he goes on about one shower for ages. Lol
