I can only speak for myself. I don't know how common they are. I'd guess very common for any new showers added.
I have an electric power shower, installed about ten years ago, but it doesn't heat the water -that comes from the cylinder.


My washing machine and clothes dryer are separate machines too. Both combined ones and separate ones are widely available.

It is recommended that you always wait for three to agree on a translation.
I speak Connemara Irish, and my input will often reflect that.
I will do an mp3 file on request for short translations.

Thanks! It really was funny, because I'd never encountered one (they're somewhat more common here than they used to be, but still relatively rare). My first night in Ireland, after everyone else had gone to bed, I decided to take a shower because I felt grungy from traveling...but I couldn't figure out how to get hot water to come out of the shower head! I took tub baths for a couple of days before it dawned on me that no one else seemed concerned about the cold water coming out of the shower, so I finally broke down and asked for help.
