Washing machine, tumble dryer (under counter, so next to the washing machine), and next to that is a sink and draining board. Cupboards underneath the sink. Worksurface on top, where I have three ironing baskets. One for hangers, one for things that have been washed but don't need to be ironed (I take that basket upstairs only one a week), the other basket for clean clothes that need to be ironed.
Wall mounted cabinets over the washing machine and tumble dryer for shoe polish kit, first aid and medicines baskets, childrens paint and coveralls, laundry detergents/softener/vanish etc.
I use the stainless steel sink to soak clothes with stains, washing hands after coming in from the garden, washing paintbrushes etc. I wouldn't replace a utility room sink. Ours is clean but there is dried on gloss paint, which doesnt bother me but looks unsightly.
Also in the utility room are vacuum cleaner, sweeping brushes, dustpan and brush, carpet cleaner, iron, mop and bucket, two clothes horses and all of our wellies and garden shoes.
On the walls are heavy duty massive hooks so that ironing done in there can be hung up on hangers before it is put away upstairs.
We also have lots of sockets at floor level and work counter level.
