Boards are nominal 8-ft lengths (2x2 frame + 1x6 surfaces) with 10% waste. A 10-gallon storage tub (about 14.5 × 20.75 in) makes the classic drop-in “sink.”

Frequently asked questions

What size should a mud kitchen be?
Build to the child. A counter height of 18–24 inches suits toddlers to early grade-schoolers; 20–22 inches is a good all-rounder. Widths of 36–66 inches and a depth around 18–20 inches are typical.
What wood should I use for a mud kitchen?
Cedar and other rot-resistant woods hold up best outdoors, and a 2x2 frame keeps it sturdy. Reclaimed pallet boards are the cheapest option — just sand them well and seal everything with an exterior, child-safe finish.
What do you use for a mud kitchen sink?
A plastic dish tub or a 5–10 gallon storage tub dropped into a hole cut in the worktop. Cut the hole about a quarter-inch smaller than the tub’s lip so it sits flush and lifts out for cleaning.
