The United Spa Difference

United Spas has been a leader in quality and excellence in the luxury hot tub industry for over 35 years.  How have we done this?  Simply put: quality products.

Every spa we produce goes through the same process.  We ensure the same level  of quality in every line of spa we build.

We custom manufacture and build each spa with attention to detail that can’t be beat.  This includes the carpentry and building of the frame, the installation of the electrical and wiring system, the plumbing for the jets and the fiberglass for the shell of the spa.

Happy Customers

“My hot tub got invaded by rats who chewed up water lines and my digital topside.  Was out of commission a couple weeks fixing the leaks and the owner Tim was able to hook me up quick with a new smart digital control and cover for a great price…”  Chief I., San Rafael

“Great place to buy a new or used spa.  After sale service is great too.  I had them come out 4 years after purchase for service and they were very accomodating, even though warranty had long since expired, and they had to travel about 100 miles.  Highly recommended.”  Steve G., Benicia, Ca

“My hot tub is awesome!  Just got it delivered yesterday.  Delivered it in a timely manner.  Good customer service.  Would highly recommend united spas to friends and family based upon my great experience.”  Robert D., San Francisco, Ca

I have owned a United Spas Hot tub for 6 1/2 years and it is still going strong!  I use it almost every day. I consider it more health care than entertainment, though it is fun to have, as well.  Luckily, I have not needed any servicing yet. I do keep the filters clean and check the water often.

Recently, I updated my home wifi and needed to reset my spa’s wifi controller.  I called in and was helped in such a speedy and friendly manner. A technician got on the phone and walked me through the update process.

After 6 1/2 years, my spa is running like new! I am so happy that I chose this company to work with. ”  Francis B., San Francisco, Ca

We bought our spa in 2021 and have loved it so much! The company was great from the start. Our visit to the showroom was low pressure and focused on educating how the spas are built and why they are durable and high quality. We wanted a spa that wouldn’t break down, that had good jets, and easy to maintain. They delivered and set up the spa then we had no issues until recently with a minor gasket leak. When we called them about the leak, they came out the next day to repair it and showed my husband what to do if it happened again. Their prices and warranty were excellent against the competitors and consistently great customer service. The quality of the spa is also fantastic and it has strong interchangeable jets which is the main feature we were interested in. We love our spa and expect to get many years out of it!”  A D., Lodi, Ca

I Called united spas for my yearly tune up and a service. Courtney picked up the phone and helped me arrange that. Matt came out and did tune and service. Both of these people were friendly, professional, helpful, very informative and educational. These two are the very type of employees that everyone business should have. I cannot say enough about the level of service I received. what a great experience because of these two. you have a customer for life. Thank you so much.”  Pete V., Modesto, Ca

We’ve had our spa for about four months and are loving it! Best investment I’ve made in a long time! When did have some trouble with keeping it clean and Tersea was so sweet and helpful. Problem solved. Squeaky clean.”  Natasha E., Pittsburg, Ca

United Spas was a very good choice for us, as we actually upgraded our spa with them.  The customer service with Eleanor is excellent and she calls annually to provide service checks.  When the techs  arrive, they are knowledgeable and very helpful each time they come.  I would recommend this spa company to anyone for purchasing a spa as well as the annual maintenance.  Very satisfied customer.”  Sistadi W., San Francisco, Ca

We bought a United Spas second hand from a private party. We called United Spas for help and advice and they treated us like we just spent $10,000 with them. Genuinely helpful, they’re a lesson in customer service and building relationships. Someday when we need a new one, guess where we’re going?:)”  Mark A., Ca
