It's not good.
The finance office should not have a restroom.
Because the restroom is a place where negative energy gathers. If there is a restroom in the finance office, the staff may get sick due to inhaling too much negative energy.
Additionally, if the feng shui of the finance office with a restroom is very bad, it can even destroy the feng shui of the finance office.
The finance office is the place where money flows the most. Therefore, the feng shui of the finance office must be good. If the feng shui of the finance office is bad, it can affect the overall development of the company.
So, the finance office must not have a restroom.

In the layout of the finance room, it should be based on stability, seclusion, and wealth attraction. The feng shui of the cash register area should follow the principles of concealment, authenticity, stability, and vitality.
Concealment: security and confidentiality, with vitality.
Authenticity: no conflict, harmony, with true energy.
Stability: immovable, accumulating wealth.
Vitality: with vitality, wealth flowing in.
It is best to have a god of wealth. A statue of the god of wealth turns gold into real money; place things on the left, and the cash register earns money well; the fan blows, and the cash register becomes rich; the light shines up, and the cash register gets money quickly; large blades, and bills fly around.
