Oswego, Illinois
Builders in Oswego's newest subdivisions poured some of the best basements in our entire service area: deep 9 foot foundations, dry slabs, and bath rough-ins waiting under the concrete. For a wellness suite, that is a running start. The rough-ins shorten plumbing for a steam shower and plunge drain, and the ceiling height lets a sauna breathe.
ONIT designs full recovery suites for these lower levels, cedar sauna, cold plunge on a dedicated circuit, vapor-sealed steam shower, heated floors, with ventilation engineered for below grade. Kendall County permits are handled by us. Free in-home design consultations and itemized quotes.
It starts with a free in-home design consultation. We measure your basement, check moisture and mechanicals, and talk through how you want the space to live. You get a design and an itemized quote, we handle permits and inspections, and one team runs the build from the first cut to the final walkthrough. Most projects take 6 to 12 weeks of construction.
We locate them first and design around them. A builder's bath rough-in typically gives us drain and supply positions we can extend to serve the steam shower and cold plunge, which avoids cutting the slab and lowers cost. During the free in-home consultation we map exactly what your builder left and show you the layout it supports.
Yes, without exception. A new foundation being dry says nothing about the humidity a steam generator and plunge will add every week. We seal the steam enclosure as a vapor envelope, install dedicated exhaust for the wellness zone, and select surrounding materials for moisture. That engineering is what keeps a new basement performing like new.
ONIT does, through Kendall County, as a standard part of every project. Wellness suites involve new electrical circuits, plumbing, and mechanical ventilation, all of which are permitted and inspected work. We prepare the documents, schedule inspections, and fold them into the build timeline, which typically runs 6 to 12 weeks depending on scope.
Tell us about your basement and we will follow up within one business day to set up an in-home visit.
