Great Bay is Great. I bought both my custom sauna and my Hot Tub from them. They are not the cheapest, but you get what you pay for. The customer service is excellent and puts them over the top. I had a few minor issues as a new spa owner, and they were available to take the time and help me out. They are reccomended for sure.

Great Bay spas made purchasing and set up of my new hot tub hassle free. Lincoln and his team are the very best at what they do. They are available anytime to answer questions or concerns that you may have. Recommend to anyone who is thinking about purchasing a hot tub!

Absolutely wonderful experience purchasing our hot tub. Lincoln was awesome to work with. No hassle, no pricing gimmicks. Honest and fair price, delivered and installed as promised. I've called with seemingly silly questions as a new spa owner, and the responses are always quick and the service comes with a smile. Highly recommended.

Three years ago we were looking for a hot tub and our friend highly recommended Great Bay. We don't live close to Portsmouth, but we took a drive up to see what Great Bay had to offer. We were very impressed by the knowledgeable sales staff. We purchased our Hot Tub from Great Bay and love it. They actually answer their phone when you call and have awesome customer service. We would go nowhere else for a spa.

We had a great experience with Great Bay Spa. We visited their showroom near the start of the COVID lockdowns and Jessica was able to help us to pick the right spa for us in a short amount of time. And they were able too get it delivered in about a week. With Jessica's help I was able to do my research in advance of visiting the showroom and the Sundance that I bought is a good quality spa.

When it comes to Spas you definitely get what you pay for. The delivery and set-up crew was also great, and I can say now that six months later their post delivery support has been great as well.

Our spa was delayed, due to back up with the manufacturer. It was not Great Bay Spa's fault, nor was there anything they could do to prevent it. But because of the inconvenience, Jamie at Great Bay Spa went out of his way to make our delivery process both cost free and hassle free. He did not have to, yet he chose to go above and beyond for us and we really appreciate it. This company truly cares about their customers, which is rare to find.

From purchase to delivery and setup, it was a very good experience. Scheduling is tough these days but GBS&S was honest and set realistic expectations. Delivery and setup crew was on time, professional and careful. We love our Tylo sauna.

We purchased a Sundance Hot Tub 12 years ago from Great Bay and have been thrilled about the product, and even more so the service and support from Great Bay! We've had issues ranging from needing service during some of the COLDEST weeks in the Winter and they have always been there for us. Recently we just replaced an Ionizer (?) and once again - fast service - and great support!

These guys are the best. I drive buy a bunch of "hot tub" dealers to buy products from them, and get their service. I'd buy another from them. BUT this one is still working awesome! You get what you pay for, and I've gotten more than my money's worth! I recommend them highly for their service, support and quality of products at a fair price.

They are always there and willing to help anytime there is a question or problem. Their service department is top of the line. The technicians are always willing to help explain and show any of the features while they are at the service appointment. Our favorite technician is Greg.

Great service by George the technician. My new house came with a hot tub and I knew nothing about them. He came out and checked the unit out for leaks and to make sure it was running properly. He patiently answered my questions and taught me about the various chemicals I need to use.

I have purchased three hot tubs during the past 30 years from Great Bay. The first was a redwood tub, and the last two have been Nordic Crown II tubs. The experience for each of these three tubs has been great. from the original purchase through maintenance and service. In particular, our most recent tub had to be installed in an existing deck. It was a little tricky to make it all come out smoothly. Tony was very helpful throughout the sales process. Tim and the crew did an excellent job with delivery and installation. I would highly recommend Great Bay.

When you first enter the store you will notice employees that are ready to help you and that are very pleasant to deal with. Tony (manager) has a incredible knowledge base on hot tubs and he helped us pick out our hot tub seven years and if I ever have a question, I can call him and he or Jess will be there to answer me. I just had my hot tub serviced by Tim and he was incredible and Very Professional.

He took the time to explain what was done and gave me many ideas on how to keep my hot tub working. This company is like a extended family to me as they all treat you with the best customer service! I'm a customer for life at Great Bay Spa and Sauna!
