Our Story

IHT's History of serving the Denver, Colorado Area

Established in 1978 as a family-owned business, International Hot Tub Company set down roots seeking to provide exceptional quality, value, and service for customers in the Denver area. In the same way, the Hiner family continued the original vision with their purchase of IHT from the original owner in 2005. Over the next 16 years, the company caught the attention of Leslie’s, who acquired IHT Hot Tubs & Fireplaces in 2021 as part of Leslie’s Poolmart, Inc. family. We are now a proud member of one of the nation’s largest specialty retailers.
