O'Fallon homes and this kind of project
A basement bathroom in O'Fallon means working in two-stories and atrium ranches from the 1985 to 2010 boom, so on our first visit we look at the rough-in stubs, the depth of the main drain and whether an ejector pit already exists.
The housing stock here: mostly 1985 to 2010 production two-stories, ranches and atrium ranches, with older ranches and bungalows near the original town center.
Most boom-era basements have a three-pipe rough-in in one corner, sometimes bumped or filled with debris, which we clear and test.
Foundations and basements in O'Fallon
Full basements are nearly universal. Atrium ranch plans, popular here, have a wall of windows at the lower level that makes for an excellent finished space. Many basements were finished by owners in the 1990s without permits, so we often find work that needs correcting.
Homes built in O'Fallon between the late 1970s and the 2000s nearly all have full poured basements, and a large share were finished once already by an owner or handyman, often without permits. We open a few walls before quoting, because what is behind them decides whether this is a refresh or a rebuild.
What is included
We build O'Fallon basement bathrooms as standalone projects or as part of a full finish. Either way the underground plumbing gets inspected before concrete goes back, and the shower gets a flood test before tile.
We take on basement bathroom work across O'Fallon, from Wyndgate to the Highway K corridor and old town O'Fallon.
What we watch for
Ejector basins in older O'Fallon finishes are sometimes unsealed or unvented, which is where sewer smell in a basement usually comes from. If you already have one, we check the lid gasket and vent connection as part of our visit.
O'Fallon properties tend to be established subdivision lots with fenced rear yards, and that affects how we stage materials, where a plumber, an electrician, a tile setter and a finish carpenter park and how debris leaves the site.
Permits and approvals in O'Fallon
The City of O'Fallon building division is where we file for a basement bathroom in O'Fallon, and the job will see underground plumbing, rough plumbing, electrical and final inspections.
Being inside the house, this project is unlikely to need sign-off from neighborhood HOAs and, in WingHaven, a master association, but we confirm any rules on containers and work hours.
Schedule and getting to you
Most O'Fallon clients see three to five weeks of construction for a basement bathroom.
From our Wentzville base, O'Fallon is fifteen minutes or so east on I-70 or I-64. That is close enough that your project lead can stop by most days.
What moves the price in O'Fallon
We price basement bathroom additions in O'Fallon from a site visit, not a square-foot figure. These are the items that change the number.
- Shower type: a prefabricated base with tiled walls costs far less than a fully tiled curbless shower with glass.
- Distance to the vent stack, the panel and the nearest exterior wall for the fan duct.
More detail
Our step-by-step method for this work, and the factors that move its price, are laid out on the main basement bathroom additions page. More about the area is on our O'Fallon page.
Basement Bathroom Additions in O'Fallon: common questions
How long does a basement bathroom take in O'Fallon?
As a standalone project a basement bath usually takes three to five weeks. In O'Fallon, permit review by the City of O'Fallon building division and material lead times affect the start date more than our calendar does.
Who will be working in my O'Fallon home during a basement bathroom?
A plumber, an electrician, a tile setter and a finish carpenter, scheduled and supervised by one Henry Hill project lead who is your single point of contact. Licensed trades are used wherever the City of O'Fallon building division requires them.
Can I have a shower, or only a half bath?
Either. If the drain line and vent are sized for it, a shower is no harder than a toilet. We check pipe sizes before promising.
