The shop is next to the toilet. Is feng shui good?

This depends on the understanding of the details around the store!

But also the internal pattern and decoration of the store.

The location of the shop is good, the interior is well grasped, and the feng shui is naturally good.

Good feng shui is not judged by whether there is a toilet next to it. There is a toilet next to it, which is neither bad nor bad.
