It seems it might be only the UK who have it in the kitchen. I’m just pointing out that it’s a bit odd….
The Brits might be the odd one out but that doesn’t make us wrong, especially when you take tradition and housing size into account….
My aunt is Canadian, a Newfoundlandlander. She has a big house, and like all the houses out there it’s big enough to have an actual laundry room. As the house is on 4 levels, the laundry room is sensibly in the furthest room away on the lowest level. For most of the year the clothes are dried in the drier but she will have to carry her clothes down 3 sets of stairs to wash and dry them, then back up to put them away. If the washer was in the kitchen it would be up and down one set of stairs and it would be easier to dry them outside in their short summer as it’s right next to the garden. As far as I’ve noticed all the Canadian houses seem similarly planned.
It’s out of sight but it’s a lot more faff.
Traditionally in the U.K. We have smaller, far older, houses that predate washing machines and dry clothes outside. So it makes more sense to put the washing machine in the kitchen.
Most newer houses have utility rooms though, but they’re generally just a kitchen extension and near a door to the garden.
I’d say we’ve got it right to be honest.
