wooden or lacquered bowl
椀 centers on a bowl made of wood or lacquer, used for serving food or drink.
椀 combines 木 (tree/wood) with 宛, which likely contributes the sound ワン. The character specifically denotes a wooden bowl.
The left side is 木 (wood), and the right side 宛 looks like a container under a roof. Picture a wooden bowl (木) shaped like a curved vessel (宛) for holding soup.
For ワン, imagine a wooden bowl so large it could hold one (ワン) whole watermelon: one -> ワン, and the bowl is made of wood.
