Lemont, Illinois
Two kinds of Lemont homes ask for two kinds of wellness plans. Up on the ridges, upscale new construction offers tall, dry basements where a full suite, cedar sauna, cold plunge, steam room, heated floors, is a ready-made project. Down near the historic hill and canal, older homes need honest evaluation of moisture and headroom before any wet rooms are drawn.
ONIT works both sides of that line, engineering ventilation and vapor control into every below-grade build regardless of vintage. Projects begin with a free in-home design consultation and an itemized quote, with permits handled by us.
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.
The honest answer starts with a site visit. Older homes near the hill vary widely in foundation moisture behavior, ceiling height, and electrical capacity, and a steam room over an unresolved moisture issue is a mistake we will not build. Sometimes correction work comes first, sometimes a sauna and plunge fit where steam does not. We tell you plainly.
Through a designed system rather than a fan on a switch. The steam enclosure is sealed as a continuous vapor envelope, dedicated mechanical exhaust moves humid air out of the suite, and the assemblies around the wet zone are built from moisture-tolerant materials. Below grade, that is the difference between a spa and a future mold problem.
Height, dryness, and access. Newer Lemont basements give us tall ceilings for a properly proportioned sauna and steam room, dry slabs for clean plunge drainage, and open framing for ventilation runs. That means fewer compromises and a faster build, typically within our 6 to 12 week range. Financing is available on larger projects.
