It was roughly four weeks from when the dishwasher, countertops, and sink went in to when the plumbing was done. Rich is a busy guy and the permit process can be painfully slow (snail mail and inaccessible inspectors.) That was four weeks of torture: doing dishes, and everything else kitchen related, in the laundry room sink with a shiny new sink and dishwasher right in front of us.
The irony is that we only cook for two, have a limited assortment of tableware, and don’t put any pots/pans/plastics/wood in the dishwasher, so we fill it about once a week. As for the disposal, everything appropriate goes into the compost so it doesn’t get a lot of use. Both are very nice to have, though, as is the deep double sink.
