New Lenox, Illinois
Big family homes south of Route 30 tend to come with big unfinished basements, and New Lenox families are increasingly using part of that square footage for recovery, not just recreation. A cedar sauna, a cold plunge, and a steam shower tucked beside the home gym turns the lower level into the hardest working floor in the house.
No hometown basement specialist really serves New Lenox, which is why ONIT treats it as a priority town. We design wellness suites around below-grade realities, with engineered ventilation and vapor control standard. Free in-home design consultations, itemized quotes, permits handled, licensed and insured.
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.
Phased builds are common in New Lenox and they work well when the infrastructure goes in early. We rough in the plunge circuit, sauna wiring, drainage, and ventilation during the first phase, then finish the wellness rooms when you are ready. That sequencing avoids tearing open finished walls later and keeps each phase's cost clear on its own itemized quote.
We treat it as an engineering problem, not an afterthought. Steam showers get fully vapor-sealed enclosures, the suite gets dedicated mechanical exhaust so humid air leaves the basement instead of settling into it, and materials near the wet zone are selected for humidity. That system approach is what makes saunas and plunges safe to run below grade year round.
A wellness zone inside a larger lower-level build usually keeps the whole project in the 6 to 12 week range. The added time comes from electrical work, drainage, and the ventilation system rather than the sauna itself, which installs quickly once the room is ready. Permits are handled by us, and financing is available on larger projects.
