Basement bathroom plumbing

A basement bathroom depends on where your drains are. Some homes can use gravity, and others sit below the sewer line and need a pump. We look at your home first and explain what the job involves.

What a rough-in is

A rough-in is the stage where water supply and drain lines are laid out, before walls, floors and fixtures are finished. In a basement, it can mean opening the concrete floor to reach the drain. Getting the placement right matters, because it is hard to change afterward.

When the drain is too high

If the fixtures sit below your main drain, water cannot leave by gravity. That is when an upflush system or sewage ejector pump comes up. We check the drain depth and the path out of the home before recommending one.

Think about backups first

A new bathroom adds more for a sewer backup to damage. If your home has flooded, or the street has, ask about a backwater valve while the floor is open. A drain camera inspection can also show the condition of the line you are tying into.
