Hi.

Putting a new bathroom in. Nice corner bath, Mira Exel shower. Gonna
feel very medetterenian!

Nice shower the Exel, but I have to turn the temprature right up to
the stop to get the really hot water. The problem seems to be that
the cold water is giving far more flow / pressure than the hot.
(Supply is a WB greenstar combi putting out 14l/min DHW. )

I've tried just closing the isolator for the shower a bit, but it
makes such a noise as the water goes through that it's not an option.
Is there a device that is designed to QUIETLY reduce water pressure in
a pipe?

Mucho thanks.

Isn't the mixer valve in the shower adjustable, to allow the hot inlet to be
open more than the cold in the central position?

If not, you could perhaps use a pressure reducer (or more strictly, a flow
reducer) of the type supplied with Torbeck cistern valves. This is a plastic
slug with a very course thread on the outside, with provides blockage and
forces the water to flow in a spiral. One of these inside a 15mm supply pipe
*may* do the trick.
