Ah, extremely annoying considering how much they cost! The water flow isn't particularly bad tbh and it's not an "eco" mixer. They actually advertise a high flow rate for the mixer and showers, which is why I was left scratching my head when comparing the flow in both bathrooms. If anything, it should be better as it's directly above the boiler. The advertised outlet flow is as follows: Maximum flow rate (at 3 bar): 22 l/min Flow rate of hand shower (at 3 bar): 22 l/min Flow rate upper outlet 22 l/min at 3 bar Flow rate lower outlet 22 l/min at 3 bar We have almost 5 bar of pressure in the other bathroom. I wonder if the installer somehow adjusted this in the newly fitted shower? Can that be done on the mixer or the inlet pipes? We have a combi that's giving us a decent flow rate to be fair (as combis go). The 16-17 l/m rate in the other bathroom (using an old triton shower head attached to bath taps) is the flow at 46 degrees. I have one of those flow rate devices to get a reading. The same test in the Hansgrohe shower is getting me at just below 12 l/m.

Hi all, Had a (hopefully) quick question about the difference between a modern manual shower mixer and old school individual hot and cold flow taps. I have decent flow and pressure in one of our two bathrooms (the older one): Hot: ~12 l/m Cold: 18-22l/m Average mixed flow: ~16-17 l/m (which is good enough) Pressure: 5 bar The other bathroom which was recently redone with a manual mixer (no flow control lever) averages around 12 l/m at the same temperature. The bathroom with the better flow rate has separate hot and cold flow taps (it's an old basic handshower attached to the bath). To get the 16-17 l/m flow rate, we're opening the hot tap all the way and then adjusting the cold to the desired temp. This way, there's a greater volume of both hot and cold mixed in. As there's no flow lever in the newly fitted shower (in the other bathroom), I wanted to know if all these mixers (without a flow lever) work by using less cold and hot water to get the desired temp. If so, is there a way of overriding that to get the maximum volume of hot and cold? Can we retrospectively adjust the new shower through the mixer (by removing the front panel) for more volume or do these mixers all work by using less water? For reference, the manual mixer is a Hansgrohe ShowerSelect (2 outlet) and has a maximum outlet flow rate of over 20 l/m and the shower has around the same. There's a way to select the output and then adjust the temp, but nothing to control the flow. Thanks
