We’re only two people in our household… We we easily run the full size dishwasher every two to two hand a half day. When we have gatherings of friends and family here, we often have to do two if not three loads. YMMV
I think I imagine myself running the washer daily, and washing a couple oddball dishes here and there.
I’m in my 40s and I’m getting my first dishwasher, so I’m used to needing to do a load at the sink for a half hour a day.
If I understand things right, my drying rack seems like it would be smaller than an 18" washer, so for the day to day operations (the time that really stacks up fast), running daily would still be a major improvement.
That said, I know how convenience is compelling, so the big question is do I want the added luxury of 6 inches wide haha… I don’t know.
