Nūva Haus

Nūva Haus is a medical spa in River North, set inside a restored historic building with original crown molding, on W Ontario St. The space blends clinical treatments with spa amenities: cryotherapy, salt float tanks, IV drips, and a private beauty bar for touch-ups after a session.

The menu runs six treatments, with the Signature Lymphatic Treatment as the standout offering. Practitioners on site include a naturopathic physician and an RN, alongside estheticians and massage therapists, so the focus leans toward functional wellness and recovery rather than pure pampering. Reviewers mention facials, massage, float tanks, and IV treatments as regular draws, with several calling out the cleanliness and calm atmosphere.

This is an adults-only, reservation-required spa, positioned at the upscale end of the price scale. It's open seven days a week, with longer hours on weekdays (10am to 8pm) and shorter weekend hours (10am to 6pm). Memberships are available for those who want ongoing access rather than one-off visits.

For floating specifically, past visitors note that no prep is needed: each float tank connects to its own private shower, and the spa supplies what's needed for the experience. Expect a quieter, more clinical take on the typical day spa, built around longevity and recovery protocols rather than a single big soaking pool or sauna circuit.
