IHT in Denver, CO

Denver, The Mile High City, or 5280, is the capital of Colorado. It is an American metropolis dating to the Old West era full of rich history. 

Larimer Square, the city’s oldest block, features landmark 19th-century buildings. Museums span every genre including the Denver Art Museum, an ultramodern complex known for its collection of indigenous works. Denver also is home of the Molly Brown mansion: the famous Titanic survivor.

Urban living is part of Denver’s allure. A short drive gets you into mountains where a few of its favorite pastimes are skiing, hiking, biking, or just walking your dog.

Denver is also a jumping-off point for world-renowned ski resorts in the nearby Rocky Mountains including Vail and Breckenridge.

International Hot Tub opened their first Denver location in 1978 and soon outgrew their original space. They moved in to the current location on Broadway more than 30 years ago. The company was purchased in 2005, by Rich Hiner, who has currently been with IHT for 37 years: sales person, Manager, General Manager and current owner.

International Hot Tub opened their I-25 at 8th Ave Zuni location in 2010. The Big Blue Building has been a Denver landmark for decades just off I-25, exit 209c / 8th Avenue on Zuni street. Denverites use it as a geographic reference point just south of Empower Field at Mile High, known to long-time residents as Mile High Stadium. So not sure where to find us? Just look for our Big Blue Building.

How did the Zini street get its name? Zuni refers to a native American Indian tribe.

The Zuni are Native American Pueblo peoples native to the Zuni River valley. The current day Zuni are a federally recognized tribe and most live in the Pueblo of Zuni on the Zuni River, a tributary of the Little Colorado River, in western New Mexico, United States.
