Darien, Illinois
Value drives basement decisions in Darien, and a wellness suite can absolutely be a value play. Much of the town's 70s through 90s housing stock carries original or dated basements, and homeowners rebuilding them are choosing recovery features that get daily use, a sauna, a cold plunge, a steam shower, over another seldom-used spare room.
ONIT builds practical family versions of these suites without cutting the engineering that below-grade wet rooms require: dedicated circuits, drainage, vapor sealing, and mechanical ventilation. Free in-home design consultations, itemized quotes so every dollar is visible, 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.
Yes, when the scope is chosen deliberately. A well-built two-person sauna and a cold plunge on a dedicated circuit deliver most of the daily recovery value, with steam showers and heated floors as additions when budget allows. Our itemized quotes price each element separately, so you decide what makes the cut instead of accepting a bundled number.
An honest evaluation. We check how the foundation handles moisture, confirm ceiling height and panel capacity, and inspect anything a previous finish might be hiding. Older basements often need modest correction work before wet rooms go in, and we would rather price that reality up front than build a sauna over a problem.
Containment is engineered into the build: the steam enclosure is vapor sealed as its own envelope, the wellness zone gets dedicated mechanical exhaust so humid air leaves the house, and surfaces around the wet rooms use moisture-tolerant materials. Done this way, the family room next door stays as dry as it was before the suite existed.
