On a side note, electric tankless water heaters are commonly installed inside showers in Germany, as are wall-mount tank water heaters. Of course with an appropriate IP rating (waterproof) and proper feed. Gas fired combined central heating boilers/ water heaters (combi boilers) are commonly found above bath tubs all across Europe and theey have pumps, electronic controls and everything running on 230V (or an internal stepdwon transformer for the electronics of course).
