What shower is best for low water pressure?
Fix the pressure, not just the shower: in south London's older houses the culprit is usually a gravity tank system, and the real solutions are an unvented cylinder, a combi upgrade, or a shower pump. Chasing 'low-pressure shower heads' treats the symptom — and rules out the rainfall heads most people actually want.
Half the poor showers in south London trace to the plumbing era, not the shower: a cold tank in the loft and a cylinder in the airing cupboard delivers gravity pressure — often under 0.5 bar upstairs — and no shower head fixes physics. The era matters because so much of Bromley, Sutton and Croydon's interwar stock still runs these systems, wholly or in part.
The genuine options, in rising order of cost: a twin impeller pump feeding the shower (£600–£900 fitted, transforms a gravity system, adds some noise); a combi boiler conversion (mains pressure everywhere, frees the airing cupboard and loft, but flow shares with other taps); an unvented cylinder (mains pressure plus stored volume — the best showering in a family house, and what we pair with most wetroom builds).
This is why we ask about your hot-water system in the first survey conversation: specifying a £300 rainfall head onto a gravity system is how people end up with an expensive drizzle. Do the system and the bathroom together — walls open once, one disruption, and the shower the tiles deserve.
