Taking a shower has
a number of advantages over bathing it is quicker and uses less
water. But, depending on the existing plumbing system, some types of
shower can be impossible to install without radical alterations. So
check what is and is not possible before buying.
Some showers have
simple hot and cold valves, like those on an ordinary mixer tap;
others use one valve to control the amount of water (the flow), and
another to control the temperature. The flow and temperature may also
be controlled by a single tap: or in some cases, only the temperature
may be variable. The controls may be thermostatic, which keeps the
temperature of the spray more stable. Thermostatic controls are
easier and safer to use than non-thermoslatic.
Whatever which type
of shower, the valve part can be connected to the outlet (the rose)
by a rigid pipe or flexible hose. A rigid pipe may look neater but a
flexible hose allows the rose to be positioned at different heights
to suit different members of the family and to be used for hair
washing if it is over the bath.
All types of shower
can be mounted over the bath. Some can be mounted over separate
shower trays: these are probably easier to use, but can require much
more installation work.
Push-on hose
Ends push over
existing bath taps. Cheap and no installation required, but water
authorities frown on their use.
Bath/shower mixer
Easy to install
replaces existing bath taps; relatively inexpensive. Can be used only
when hot and cold water come from a storage cistern or with certain
multipoint gas water heaters.
Shower mixer -
non-thermostatic
Usually mounted over
a separate shower tray may need a lot of plumbing and waste
installation. Some types have hot and cold valves; others may have
temperature and flow controls.
Shower mixer -
thermostatic
Usually mounted over
a separate shower tray may need a lot of plumbing and waste
installation. Usually has temperature and flow controls.
Electric shower
heater
Can be mounted over
a bath or a separate shower tray. Takes its water from the mains cold
water supply. Water is heated instantaneously as it passes through
the heater - the spray may not be as forceful as with a conventional
shower. Special electric wiring needed, but an electric shower can be
used where a conventional type is impracticable.
Power shower
Both supplies to the
mixer valve are pumped to give a choice of sprays. Needs separate
cubicle and careful plumbing. Uses more water.
