I have a tiny little European laundry in the main bathroom and I love it!
Washing machine fits perfect, and it's a big one.
Dryer is on the undercover back porch (a back door from bathroom leads to this porch), covered in the plastic it came in when not in use. Porch also has two clothes horses set up. The porch is a side one and isn't our main back one so visitors never see it.
Each bedroom (4 in total) has a dirty clothes basket.
Lots of times anyway when the kids have a shower/bath they chuck any dirty clothes straight in the machine. I keep 2 laundry baskets stacked on top of machine or sink.
Don't have a cupboard but the space leftover next to the sink and machine fits the vacuum cleaner and enjo mop and buckets.
One small shelf above the sink fits everything I need to clean with.
This is all behind two doors, euro laundry style.
It's surprisingly perfect for us, and we are a family of 6 nearly 7!
