Here in Europe and I guess specifically in Latvia most have washers or washer+dryer in 1 combo in almost every home or even individual apartment. My washer/dryer is in bathroom but I have seen people having them also in the kitchen. Depends how spacious said living spaces are. Newer homes or bigger homes have dedicated laundry rooms.
Recently in one of the bigger shops here they opened a laundromat and whenever I go to the shop I hardly see it used. Maybe students use them if their dorms don't have washers/dryers or people who have run into trouble with their machines use them. Maybe it is hardly used due to the unreasonably high prices. I think it was around 7 euros per 9 kilo wash.
I found American washers and dryers are so different from what we have here. Like, dryers for one work on completely different principles than what I encountered in States.
Can you be more specific about dryers? Ours use electricity or gas to heat air, and tumble the clothing in a drum while venting the air outside. There are newer (but expensive) machines which work more like a dehumidifier and collect the water differently.
The ones I saw in America were the ones that heat air.
Ours works like dehumidifier I would say. :)
There are also sophisticated systems which work like a heat pump, but those are exceptionally expensive, at least here.
