A basement bathroom saves trips up the stairs and makes a guest room or rec room work. The hard part is the drains. They have to run to your sewer line, which usually means cutting a trench in the concrete floor. If the fixtures sit lower than the sewer line, a pump has to lift the waste up to it. Some houses were built with drain stubs already in the floor, which saves a lot of cutting.
What's included
- On-site look and a written quote
- Finding the sewer line and checking its depth
- Saw-cutting and trenching the slab for drains, then patching it
- Rough plumbing and the rough-in inspection
- An ejector or up-flush pump where the drains need one
- An exhaust fan vented outside
- Framing, drywall, tile, vanity, toilet, and shower or tub
The process
- Look and quote. We find your drain line, check for existing stubs, and give you a written quote with the layout.
- Permits. We apply for the building and plumbing permits your town requires.
- Cut and rough in. We trench the floor, run drains and supply lines, and pass the rough-in inspection.
- Patch and frame. We patch the slab, frame the walls, and run the fan and wiring.
- Finish. Drywall, tile, fixtures, and the final inspection.
What affects the price
- Distance to the drain line. More trenching means more cost.
- Pump or no pump. Fixtures below the sewer line need one.
- Full or half bath. A shower or tub adds drain, water, and tile work.
- Shower type. A tiled shower costs more than a one-piece unit.
- Fixtures and tile. Your choices here move the price both ways.
Questions homeowners ask
- Can I put a bathroom anywhere in the basement?
- Almost, but location changes the price. The closer it sits to your main drain and vent, the less floor we cut. Look for capped pipes coming up through the floor. Some houses have a bathroom rough-in already in place.
- What's an ejector pump, and do I need one?
- It's a sealed pit with a pump that lifts waste up to the sewer line. You need one if the toilet and shower drains sit lower than the line leaving your house. We check the depth at the quote and tell you whether you'll need one.
- Should I do a half bath or a full bath?
- A half bath is a toilet and sink, so it costs less and needs less floor cutting. A full bath adds a shower or tub. If you might want a guest suite down there later, rough in the shower drain now, even if you finish the shower later.
- Do I need a permit for a basement bathroom?
- Yes. Plumbing work needs a permit and inspections. In Tea and Harrisburg, plumbing permits come through the state. Sioux Falls handles its own. We include the permits in the quote.
