One Plumbworld 'Architekt' thermostatic bar shower with rainfall monsoon head.
Used for about 6 months but our pressure not high enough so changed. The spec says as low as 0.5 bar but more suited to a mains pressure system rather than our gravity system.
Looks similar to the Plumbworld pic, but has the switchover valve internal to the bar, ie it doesn't need the lump above the bar in the pic.
