I will be installing a new shower shortly and was wondering if any of
you had particular recommendations? Any pros and cons to look out for?

The water system provides hot and cold water at mains pressure
(modulating combi). Static water pressure is OK ( 3bar), flow rate up
to about 15l/min is available from the hot supply - although I would
like to use less than that so as to have something left for the rest of
the house.

The Mira 415 is the one to go for. Dedicated to mains pressure systems. It
is not thermostatic and has an integral pressure balancing valve. The combi
provides the constant temperature, so no need for a thermostat cartridge in
the mixer. It works very well indeed. When you have equal flow and
pressure on both hot and cold you don't need a thermostat (except where
maybe children are about and they could play about). The 415 adjusts the
hot and cold to equal pressure when any fluctuations. The reaction is far
faster than a thermostat. The 415 is also simpler and if the thermostat
cartridge goes it is usually over £100 to replace. Go for the Mira 415.
