3/4" connection for concentric mixer shower?

[Jacques LeRat]

Does anyone know of a concentric mixer shower valve that will fit 3/4" threaded connectors coming out of the wall @ 150mm centres?
I would like to replace a bar mixer valve (3/4" threaded connectors @ 150mm spacing) with a concentric mixer valve, but concentric mixer valves all seem to fit onto 15mm pipework coming out of the wall. I would need to break into the tiling and the wall to change the threaded connectors to plain 15mm pipe, which I would rather not do. There are plenty of bar mixer valves that will fit straight onto 3/4" threaded connectors but I haven't found any concentric mixer valves that do. Just wondering if anyone else has come across this?
