How about changing the toilet into a kitchen? What's the point of having wood?
The main problems are the flue and the smell of water. Nowadays, high-rise buildings all use flues, and the walls are somewhat breathable, so the room will definitely smell of oil smoke. It is not good to live here. But if you change the toilet into a kitchen and cook in the toilet, the water will smell bad and affect your life to some extent. Feng Shui, believe it or not. If you believe it, you will be forgiven at all. If you believe it, it's really bad. Changing the toilet into a kitchen will pollute the place, and your cooking is not good for your health. It is also incompatible. But if it is really not enough to live in, you must find a professional to drain the flue and make it waterproof.
