Glenwood Hot Springs: one huge pool, a children's area and no reservation needed.
Iron Mountain: smaller pools at a range of temperatures, the sauna area and cold plunges.
Either works as an evening, but the drive back up valley at night in winter is the part to plan: a driver means nobody has to.

We plan the soak around the rest of the trip: a driver down valley and back after dark, and a massage or dinner at the house when you return.

Leave the house mid-morning with nothing to carry. A private car takes you down the valley to the springs, with robes, towels and cold water waiting in the back. Soak for as long as you like, have a slow lunch in Glenwood, and come home to a massage and dinner at the house.

A day that never leaves the residence: a late breakfast, a massage in the afternoon light, a long lunch cooked for you, and oxygen and water on hand. For the day after a big ski day, or the day before you fly home.

A car and driver on call for dinner and the night out, so nobody hunts for a taxi at midnight.

A therapist at the residence after travel or skiing.
