Though not made for the outdoors, it may be possible to use the mini kitchen in the open for a summer. As the sink is stainless steel and the frame is powder coated metal, it should be able to withstand a summer’s heat and rain. The plastic hooks may not survive though. So it may be best to keep the mini kitchen in the shade after the BBQ.
It’s pretty affordable too, with the LILLVIKEN water trap and strainer, and LAGAN kitchen mixer tap included in the price, but packaged separately. You can tuck a minibar under the sink too.
