imo, the only reason to have a gridded out dungeon is if there will be combat happening throughout the dungeon which is a ton of work. Pic related in thge left is a what is great when you use >>96510563
>describe things and ask players what they're doing
Because chances are, your players don't have a map of a fucking dungeon so they have no reason to know what the layout is.

>you're in a room [description] with [materials], [treasure], and [clues] and you see several door ways to your left, and two more ahead of you etc.

Is all you need, they tell you what they want to do, and you play it out. If some of the rooms have combat, you can just make a map for that room. keep it simple. Even more fun, a player might try to map out a dungeon based off the clues and descriptions you give which is another way to keep players engaged. You can use secret doors and hidden rooms as otehr ways to have players involved
