Pool Spas & Hot Tubs in Phoenix, AZ
Build a custom in-ground spa right into your pool, raise it as a dramatic spillover, or add a hot tub to a pool you already own. We design, build, and plumb spas with the jets, heating, and automation you want — integrated with your pool so the water, finish, and style all match.
An attached spa turns a swimming pool into a year-round retreat. In Phoenix, a heated spa is usable on cool desert evenings long after swim season ends, and when it spills over into the pool it becomes a design feature as much as a place to soak. We Fix Ugly Pools® has built and integrated custom spas with Valley pools since 2001, and we fit the spa to your pool, your deck, and your budget.
What is the difference between a spa and a hot tub?
People use the words interchangeably, but the way they are built is different. A spa is permanently built into the ground — usually in concrete or gunite — and is most often attached to a swimming pool, sharing its plumbing, heater, and finish. A hot tub is typically a self-contained, free-standing unit that sits on a pad and runs on its own equipment. Both use heated water and jets for hydrotherapy; the choice comes down to whether you want the spa tied into your pool and backyard design or a stand-alone unit you can place and move.
Because an integrated spa shares equipment and finish with the pool, it reads as one cohesive water feature instead of a separate box in the yard. That is the look most of our Phoenix-metro clients are after, and it is what we build best.
Spa and hot tub options we build
Spillover spas
A raised spa that cascades a sheet of water into the pool — the most popular integrated design in the Valley.
Raised & flush spas
Raise the spa above the waterline for a bold profile, or set it flush with the deck for a clean, modern line.
Spa added to an existing pool
We can add an attached spa to a pool you already own, most efficiently as part of a remodel.
Therapy jets & seating
Custom jet layouts, loungers, bench seating, and foot wells designed around how you want to soak.
Gas & electric heating
Natural-gas and electric heat-pump options sized to bring your spa up to temperature fast.
Smart automation & lighting
Phone-app control of heat, jets, and color LED lighting so the spa is warm and glowing when you walk out.
A spa that becomes the centerpiece
A raised spillover spa with fire bowls and LED lighting turns the whole backyard into an evening destination. When we build the spa alongside new tile, coping, and an interior finish, everything matches and you only mobilize once.
Can you add a spa to an existing pool?
Yes. Adding an attached spa to a pool you already own is one of the most rewarding upgrades we do, and the smartest time to do it is during a pool remodel. While the pool is already drained for resurfacing and retiling, we tie the new spa into the existing shell, run the plumbing, and finish both at the same time so the spa and pool share one look.
A concrete or gunite spa lets us shape it to your yard and pack in features — want extra jets and a foot massager? We will build around what you ask for. Prefer a simpler path? We can also set and plumb a self-contained hot tub to suit your space.

Automation & startup
We set the heat, jets, lighting, and app control, then walk you through running and maintaining your new spa.
How much does it cost to add a spa or hot tub in Phoenix?
Every spa is quoted after we see your pool in person, because the price depends on whether the spa is attached to an existing pool or built with a new one, its size, and the features you choose. As a planning guide, a spa is commonly added during a pool remodel as part of a mid-to-upper feature tier that typically runs $15,000 to $30,000 for the added features and finishes. On a new pool build, a spa is usually part of a project in the $38,000 to $60,000+ range, with the higher end reflecting a pool that includes a spa and other premium features. We will tell you honestly where your spa lands once we understand the scope, and we put it all in writing first.
Jets, heating, and automation that fit Arizona
The equipment is what makes a spa feel luxurious, so we size it to the job. Therapy jets are laid out around the seats and loungers where you actually want pressure, and a dedicated heater — natural gas for fast heat-up, or an electric heat pump for efficiency — keeps the spa ready on cool desert nights.
Modern automation lets you warm the spa from your phone on the drive home, dial in jet speed, and set color LED lighting for the evening. Pair the spa with other pool features like fire bowls or water features, and explore our full range of custom Arizona hot tubs and spas and dedicated swim spas.
The benefits of adding a spa to your pool
Warm water has been used for relaxation and recovery for thousands of years, and a spa brings that within a few steps of your back door. Soaking in heated, jetted water helps blood vessels widen so nutrient-rich blood moves through the body more easily, and the warmth and buoyancy ease tension in tired muscles. Homeowners tell us a spa is where they unwind at the end of the day and where family and friends gather on cool evenings. Common reasons our clients add one include:
- Relaxation. A warm soak helps decrease everyday stress and tension.
- Sore-muscle relief. Heat and jets soothe tight, overworked muscles.
- Back-pain comfort. Buoyancy takes pressure off the lower back.
- Better sleep. Many people wind down more easily after an evening soak.
- Year-round use. A heated spa stays enjoyable through Arizona’s cooler months.
- A gathering spot. It becomes the social center of the backyard.
