Your laundry room/bathroom are your wealth corner. You should treat it to the best of your ability. Put in some red tape/ribbon around the pipes. Put some gold or green towels in your bathroom. Make your bathroom look rich and opulent. Put some gold coins or a money tree picture in your laundry room.

It's best to treat both levels of your home (or multiple). But particularly, the section you "live in" the most. But any stagnant area needs to be especially treated, which is easier because it's stagnant.

The movement of people through an area helps to move the energy. So keep your laundry room and bathroom uncluttered so that they don't "push people out" through clutter or lack of space.
