Custom Hot Tubs and Inground Spas Built With Your Pool in Sandy, UT
Designed as Part of a Complete Pool Experience
Here’s the thing. Truly custom hot tubs are not standalone products. They are engineered, shaped, and built as part of a larger pool design. That is exactly how we do it at Intermountain Aquatech Pools & Spas.
We design and build custom inground spas that are fully integrated into residential and commercial pool projects across Sandy, Salt Lake Valley, and throughout Utah, Idaho, and Wyoming. These are not prefabricated drop in units. Every spa is custom formed, plumbed, and finished to match the pool, the space, and how you plan to use it.
If a homeowner wants only a hot tub, the right solution is an above ground spa. We sell and service those as well, and homeowners typically handle installation. Custom inground spas, on the other hand, are always built with a pool. That approach ensures performance, longevity, and a finished look that feels intentional, not added on.
We guide you from design through construction with one team, one plan, and no handoffs. If you are still deciding who to work with, start here: how to choose the right pool contractor for your dream backyard oasis.

What Clients Say About Our Pool and Spa Work
When we need specific parts for our pool we always go to Aquatech. They are so knowledgeable and helpful. Jason was outstanding with his help this past week. It makes a big difference to a novice like me to get expert help in resolving pool problems.
Chad is a lifesaver! He is responsive, professional, and always gets the job done no matter how busy he is. I have sent him texts and photos about pool questions, even after-hours, and he goes above and beyond to help us out. Highly recommend!
Shout out to the Intermountain Aquatech team that installed our pool this year! Over the course of the install Intermountain Aquatech maintained the timelines they promised, the cost they quoted out, and a strong level of professionalism and communication through the entire process. The Project Manager Curtiss and His team Josh, Tim, Saul, and Danoto, took care of us through every step of the process. Curtis ensured that we were always informed on what to expect through each step of the process. The team was top notch in being responsive to questions and concerns if they came up. Kevin did a great Job on our design and helping to walk us through all the options available to us during the pre-build process. The entire team worked hand in hand with our local municipality and other third party vendors to make sure timelines were met and we were getting the highest level of attention to our project by all involved. I would recommend the third party vendors they use for any job as well. Finally, Kaitlyn and her team ensured that billing and invoicing was always correct and quickly addressed any questions that we had regarding costs and payment. I appreciate all that was done to get us into our pool! During our pool contractor search we met with multiple companies for bids. Intermountain Aquatech was the best priced ( by far) and had the most experience of all the companies we had bid our job. Curtiss, thank you for all you did through this process we are excited about the outcome and what we get to enjoy for years to come. We greatly appreciate all you put into the project! Brad, thank you for taking the time through the sale process to hear us out on what we were looking for. You have an amazing team!
Very knowledgeable and helpful and the store has a good selection of products. There is also a service department!
We couldn't be happier. Ryan and Chad did some detailing on our pool and did a terrific, thorough job. We appreciate their efforts.
Aquatech replaced our pool cover recently. My husband was so impressed by the pride in workmanship of the two installers, as it is so hard to find these days. The experience was top notch and our pool cover works like a dream!! Thank you Aquatech, Alan and your great installation team.
I had a nice younger gentlemen named Gage help me with my water testing. He was very efficient and quick with his work, super kind and seemed to really care about his job! He also was really great with explaining what everything meant and what the levels should look like for each, which that helped a lot with my understanding of how all the chemical stuff works and that was great!
Curtis came out today and fixed my problem with my Pentair system at a minutes notice! Not only did he fix it he also explained to me how the system works. The guy gets 10 STARS IN MY BOOK! Thx Curtis
Derek Hale, in the parts department, is the best! He cheerfully helped me find the part I needed, which took some effort since it was an obscure part and I did not know enough about the brand to help him. I've always had great customer service at Aquatech and will be back!
Why Skipping Proper Spa Planning Costs More Than You Think
When a Hot Tub Is Treated as an Afterthought
A lot of problems start when a spa is treated like an accessory instead of part of the system. Poor placement. Awkward steps. Weak jets. Equipment that struggles to keep up. These issues are expensive to fix later and frustrating to live with.
An inground spa ties into pool plumbing, electrical, heating, and circulation. When that is not planned correctly from the start, efficiency drops and wear increases. What looks fine on day one can become a maintenance headache within a few seasons. A big part of avoiding that comes down to smart equipment choices, and this pool equipment guide lays out what matters.
What this really means is simple. If you want a custom spa, it needs to be designed with the pool from the beginning. That is how you get consistent heat, proper jet pressure, and a layout that feels natural to use.

Frequently Asked Questions About Custom Hot Tubs and Spas
Do you sell above ground hot tubs?
Yes. We sell and service above ground spas for homeowners and families who want a hot tub without building a pool. This is the most practical option when you want faster ownership, a known price point, and a spa that is engineered to perform as a standalone unit.
Here’s what you can expect from the process. We help you choose the right size, seating layout, and jet configuration based on how you will use it. Then we walk you through what your home needs to be ready, including placement, access, electrical needs, and a realistic plan for water care. Installation is typically handled by the homeowner, mainly because site conditions and delivery logistics vary, and many buyers already have a preferred approach for pad prep and electrical. Even when you handle install, you are not on your own. We provide guidance before delivery and support after the spa is running, including service and maintenance help when you need it.

How much does a custom inground spa cost?
A custom inground spa is priced as part of the complete pool project, because it is integrated into the pool design, equipment, and construction schedule. The final cost depends on several real factors, and you should know what those are before anyone throws out a number.
The biggest cost drivers include the spa’s size and shape, the type of spillover or edge detail you want, the finish materials, the number and style of jets, the seating layout, and how the heating and circulation are engineered. There is also the question of how the spa integrates visually with the pool, such as elevation changes, stonework, and matching finishes. On the equipment side, we consider pump selection, plumbing design, heater capacity, and control systems, because the spa needs strong jet performance and reliable heat without compromising the pool’s efficiency.
If you want a general cost baseline for the pool side of the project, this page helps set expectations: how much does it cost to install an in ground pool. The most accurate next step is a design consultation where we can discuss what you want, what your yard allows, and what will perform well long term.
Are custom spas more expensive to maintain?
Not when they are designed correctly. Most maintenance problems come from poor planning, not from the fact that a spa is custom.
A properly built inground spa that is integrated with the pool is designed around balanced circulation, correct plumbing, and correctly sized equipment. That matters because it stabilizes temperature, helps filtration do its job, and keeps chemical demand predictable. When equipment is undersized or plumbing is routed poorly, you can end up with weak jets, uneven heating, and water that is harder to keep clean. That is when costs climb, because you are constantly fighting the system instead of enjoying it.
Maintenance also depends on how you use the spa. Frequent use, heavy bather load, and lots of body oils or lotions can increase sanitizer demand. That is normal. The solution is a simple routine and periodic service checks. If you want to understand the equipment side better, this pool equipment guide explains what impacts performance and upkeep. And if you want to see heating options that affect operating cost, read what are the different types of pool heaters.
