Basement Bathrooms in Tinley Park, IL

Plenty of Tinley Park basements were finished decades ago without a bathroom, and the trip upstairs gets old fast. In the 80s and 90s housing stock, an ejector system is usually the answer, pumping waste up to the main sewer line so a full bath can go almost anywhere.

ONIT Restoration builds the whole room, not just the plumbing: tiled showers, heated floors, quiet exhaust ventilation, and finishes that update the dated space around it. Free in-home design consultations and itemized quotes, with financing available on larger projects.

FAQ

Basement Bathrooms in Tinley Park: Questions

Can you add a bathroom to a basement that is already finished?

Yes. In Tinley Park this is one of our most common projects, adding a bath during a remodel of an older finished basement. We open only the areas needed for plumbing and electrical, set the ejector system, and rebuild cleanly. Many homeowners refresh the surrounding rooms in the same pass.

Is an ejector pump loud or smelly?

Not when it is installed correctly. The basin is sealed with a gasketed lid and vented through the plumbing stack, so odors stay in the pipes. The pump runs in short cycles you will barely notice. Problems come from bad installs, which is why the work is permitted and inspected.

What does a basement bathroom cost in Tinley Park?

It depends mostly on the plumbing path and the finish level, which is why we quote after a free in-home consultation rather than over the phone. Every quote is itemized, so you see the ejector system, tile work, fixtures, and ventilation as separate lines and can adjust the scope yourself.
