New Toilet Installation
Adding a Toilet Where None Existed
Adding a half bath, finishing a basement or building an ADU? Our plumbers handle new toilet installation from the drain, vent and supply rough-in through the final set and inspection.
New Toilet Installation That Includes the Plumbing Behind It
Installing a toilet in a brand-new location is a different job from swapping an old one. Before any fixture can be set, the space needs a drain line large enough for a toilet, connected to the building sewer with proper slope. It needs a vent so the toilet flushes and drains without gurgling or siphoning nearby traps. And it needs a water supply line with a shutoff valve. Together, this underlying work is called the rough-in.
Our plumbers plan the rough-in around your floor plan and existing plumbing. We locate the nearest suitable drain and vent connections, calculate the slope and route for the new lines and confirm that the location meets code clearances. In slab homes, connecting a new drain may require opening the concrete floor. Permits and inspections are handled along the way, so the finished bathroom is fully approved before the new toilet goes in.

Options for Installing a Toilet Below the Sewer Line
Basements and lower-level spaces often sit below the main sewer line, which means waste can’t simply flow downhill to the street. If the sewer is deep enough, a conventional toilet with a gravity drain may still work, usually requiring a trench through the slab. When the drain sits too high, other solutions are needed, and choosing the right one early in planning prevents costly redesign and delays once construction is underway.
A sewage ejector system collects waste in a sealed basin below the floor and pumps it up to the sewer line. It supports a full bathroom with a standard toilet. An upflush or macerating toilet sits on the finished floor and grinds waste before pumping it through a small pipe, often with less concrete work. Each option has different installation needs, maintenance requirements and costs, which we’ll compare with you during planning.

Benefits of Professional New Toilet Installation
Professional installation ensures new drain and vent lines are sized and sloped correctly, preventing clogs, gurgling and slow drainage. Permitted, inspected work protects resale value and insurance coverage. Correct flange height and clearance planning avoid problems once flooring and walls are finished. Below-grade solutions are carefully matched to your space and budget. And an added bathroom often increases everyday convenience, livability and overall home value for many years to come.

Code Clearances for a New Toilet Location
A new toilet needs enough space around it to meet plumbing code and feel comfortable to use. Planning these clearances early avoids redesigns.
Codes typically require at least fifteen inches from the center of the toilet to any side wall or obstruction, and at least thirty inches between the centers of adjacent toilets. Clear space in front of the toilet is also required, commonly twenty-one to twenty-four inches depending on the code your area follows.
Doors shouldn’t swing into the required clear space, and toilet paper holders, vanities and shower walls must be placed with these clearances in mind. Accessible bathrooms have additional requirements. We review your layout against local code before rough-in begins, so the finished room passes inspection.
How Our New Toilet Installation Works
We review your plans, visit the site and identify the best drain, vent and water connections for the new toilet location.
You’ll receive a proposal covering rough-in routing, any concrete or wall work, below-grade solutions if needed, permits and cost. After permits are issued, we install the drain, vent and supply lines, set the flange for your finished floor height and schedule the rough-in inspection with your building department.
Once walls and flooring are complete, we install the toilet with a new seal, closet bolts and supply line, then level and secure it. The system is tested with multiple flushes, checked for leaks and inspected for final approval, completing your new bathroom and closing out the permit.

New Toilet Installation Questions Answered
Can a toilet be added anywhere?
Almost anywhere with planning. It needs a drain, vent and water supply. Distance from existing plumbing and floor construction affect cost and complexity.
Is a permit needed to add a toilet?
Usually, yes. Adding a toilet involves new drain, vent and supply plumbing, which most jurisdictions require permits and inspections for.
What is an upflush toilet?
It’s a toilet with a macerating pump that grinds waste and pumps it to the sewer, useful where gravity drains aren’t practical.
Can a toilet go on a slab?
Yes. The slab is cut to install the new drain, connected to existing lines and patched once the plumbing passes inspection.
How long does adding a toilet take?
Rough-in plumbing often takes one to three days, with final installation after walls and flooring are finished. Inspections affect overall timing.
