What Our Customers Say

"I own a cleaning company in Denver. We balance and maintain hot tubs along with drain and fills. These guys have top of the line products. Extremely fair pricing for the consumer side as well! Highly recommend! Great guys inside to help. If you don’t have a hot tub frog kit! Go grab one today! All of my clients use them :)"

"We met Tracy and IHT at Costco. Wife & I were talking about a hot tub, but nothing serious. We saw the quality, price and how well we were treated and became more focused. They help with demo, pad along with electrical. Tracy and the crew were fantastic. We found the tub we wanted. IHT along with Costco exceeded our expectations."

Gene K.

"Tracy was great to work with. Very communicative and everything was nice and easy from start to finish. Delivery coordination with Kim was also very simple. Great experience overall and very excited for our new hot tub!"

Eric M.

"The staff and crews that work for International Hot Tub are amazing very professional, honest, have integrity. They helped me to get a new Covana cover covered under a warranty instead of having to pay $12,000 out-of-pocket I paid a few thousand dollars out-of-pocket."
