I’m David Brabant, owner of Creative Edge Pools with over 30 years of hands-on experience building custom gunite pools and spas throughout Massachusetts and New Hampshire. We’ve designed and installed countless gunite pool with spa combinations, helping families create their perfect backyard retreat.

Why Choose a Gunite Pool with Spa
Picture this: you’ve just finished a long day at work, and instead of collapsing on the couch, you step into your backyard oasis. The warm jets of your gunite pool with spa melt away the tension in your shoulders while you watch the sunset reflect off your pool’s surface. This isn’t just a dream – it’s what hundreds of our clients experience every single day.
After three decades of building custom pools and spas throughout Massachusetts and New Hampshire, I’ve seen how a gunite pool with spa transforms not just backyards, but entire lifestyles. The combination offers something truly special that you simply can’t get with other pool types or standalone hot tubs.
The health benefits are remarkable and backed by real science. Hydrotherapy improves circulation, reduces joint pain, and provides genuine muscle recovery after workouts. We’ve had clients tell us their evening spa routine has replaced their need for sleep aids – the warm water naturally prepares your body for rest.
But here’s what really sets gunite apart: unlimited design freedom. While other pool types lock you into predetermined shapes and sizes, gunite lets us create exactly what you envision. Want a heart-shaped spa? We can do that. Prefer clean geometric lines that match your modern home? Absolutely.
The lifetime durability factor is huge, especially here in New England where freeze-thaw cycles can be brutal. Properly built gunite construction withstands decades of use and weather. I’ve personally resurfaced gunite spas that were installed in the 1980s – the underlying structure was still perfect.
Your property value gets a significant boost too. Real estate agents consistently tell us that integrated spas create that “wow factor” that helps homes sell faster and for more money.
Top Benefits at a Glance
The stress relief aspect never gets old. There’s something almost magical about settling into those bubbling jets after dealing with traffic, deadlines, or teenagers. The combination of heat, buoyancy, and massage creates an instant reset button for your nervous system.
For muscle recovery, athletes and weekend warriors alike swear by their spa time. The warm water increases blood flow to sore muscles and helps flush out the lactic acid that causes stiffness.
Family fun takes on new meaning when everyone from grandparents to grandkids can enjoy the same space safely. The shallow seating areas work perfectly for younger children, while adults appreciate the deeper therapeutic benefits.
Four-season enjoyment might be the best part, especially in our New England climate. While your pool takes a winter break, your spa becomes even more appealing. There’s something wonderfully rebellious about soaking in 104-degree water while snowflakes melt on your shoulders.
Unlimited Customization Options
This is where gunite construction really shows its superiority. Free-form designs can mimic natural hot springs, complete with rock waterfalls and planted edges that make you feel like you’re in a mountain resort.
Geometric lines appeal to homeowners with contemporary tastes. Clean rectangles, perfect circles, or sophisticated octagons complement modern architecture while maximizing seating efficiency.
Vanishing edge or spillover designs create stunning visual drama as water cascades from the spa into the pool below. It’s like having your own private waterfall, and the sound of flowing water adds another layer of relaxation.
Mosaic tile work transforms functional surfaces into artistic statements. We’ve created everything from simple accent bands to elaborate underwater murals that become conversation pieces for years to come.
The key is understanding that every family uses their outdoor space differently. The beauty of gunite construction is that we can create exactly what fits your lifestyle and your dreams.
Design, Construction & Cost Guide for Your Gunite Pool with Spa
Building a gunite pool with spa is a complex process that requires careful planning and skilled execution. Let us walk you through what’s involved, from initial design to that first relaxing soak.
The process begins with detailed project planning and excavation, where we carefully shape your backyard according to approved plans. The rebar cage installation is critical for structural integrity, creating a steel framework that will support the gunite shell for decades.
The gunite application itself is where the magic happens. Using high-pressure pneumatic equipment, we spray a mixture of cement, sand, and water onto the rebar framework. According to the American Shotcrete Association, this construction method provides superior durability and design flexibility for pool applications.
The 28-day curing period is non-negotiable. During this time, the gunite reaches its designed compressive strength of 4,000-5,000 psi. We often use this time to work on surrounding hardscaping and landscaping elements.
Finish options include traditional plaster, pebble finishes that can last 20+ years, or premium tile work. Modern automation systems can control everything from water temperature to jet operation to lighting.

Choosing the Perfect Shape for Your Gunite Pool with Spa
Round/Circle: This is the most popular choice and most economical to build. Round spas offer excellent water circulation with no corners for debris collection and create a natural social environment where people face each other.
Square/Rectangle: These work beautifully with contemporary designs and can provide extra-wide bench seating along the long side – perfect if you have a scenic view you want to face.
Octagon: This shape approximates a circle’s benefits while creating eight equal seating zones. It’s a nice compromise between efficiency and structured geometry.
Custom Organic: For free-form pools, we often create spa shapes that echo the pool’s curves, creating stunning visual continuity.
The key is matching your spa shape to your pool’s overall geometry and intended use. We always ask: How many people do you typically expect to use the spa at once?
Jet & Pump Sizing Essentials
Each spa jet needs approximately 15 gallons per minute (GPM) of flow for a strong, therapeutic experience. With a typical gunite spa having 7-10 jets, you’re looking at 105-150 GPM total flow requirement.
A standard 3+ HP pool pump can deliver around 120 GPM under typical conditions, which works for 8 jets but starts to struggle with more. For spas with 11+ jets requiring 165 GPM, you’ll likely need dual pump systems or upgraded equipment.
One critical point: jet placement and count must be finalized during construction. Unlike portable spas where you can add or move jets later, gunite spa jets are permanently positioned.
Gunite Pool with Spa Costs & Timeline
For a complete gunite pool with spa project, budget at least $100,000 for a turnkey installation. This includes excavation, gunite shell, equipment, basic finishes, and standard decking. Premium finishes, complex shapes, or extensive landscaping can push costs significantly higher.
Adding a spa to an existing gunite pool typically starts around $25,000, but this varies greatly depending on complexity, access, and desired features.

Timeline-wise, the actual gunite work takes 4-6 weeks, but complete projects typically span 3-6 months when you include design, permitting, excavation, construction, and finishing work.
Cost drivers include site access and soil conditions, complexity of shape and features, quality of finishes and equipment, and local permit requirements.
Placement & Configuration Best Practices
Inside-Pool Spa: Positioned within the pool perimeter, these spas share the pool’s water level and create a seamless look. They’re great for families with children since there’s no step up or down between pool and spa.
Raised Spillover: These spas sit above pool level, creating a waterfall effect as heated spa water cascades into the pool. The visual drama is stunning, and the raised position makes entry easier.
Flush Deck-Level: These spas are built level with your deck, creating clean sight lines and easy access. They work particularly well with infinity edge designs.
Consider prevailing winds when positioning your spa. We often recommend some form of windscreen or strategic landscaping for comfort.
Care, Maintenance & Longevity
Here’s the truth about maintaining a gunite pool with spa: it’s actually easier than managing separate systems. Since your pool and spa share the same water and filtration, you’re essentially caring for one large body of water instead of juggling two different maintenance routines.
Weekly brushing becomes your best friend with gunite surfaces. The material’s slightly porous nature can harbor algae if neglected, but a quick brush twice a week keeps everything sparkling.
Water chemistry management is surprisingly straightforward with integrated systems. Your spa chemistry affects the pool and vice versa, which sounds complicated but actually simplifies things.
Professional acid washing every 3-5 years works wonders for restoring that fresh appearance. It’s much less expensive than full resurfacing and can add years to your finish life.
Heater efficiency becomes crucial since you’re heating water to higher temperatures more frequently. A properly sized 400,000 BTU heater can bring your spa from pool temperature to a toasty 104°F in just 30-45 minutes.
Resurfacing typically becomes necessary every 15-20 years, depending on how well you maintain water chemistry and usage patterns. The beauty of gunite construction is that the shell can be resurfaced multiple times.

Routine Maintenance Checklist
Your weekly spa routine doesn’t have to be complicated. Here’s what we recommend:
Water chemistry needs attention first. Test and maintain pH levels between 7.4-7.6, keep total alkalinity at 80-120 ppm, and maintain calcium hardness between 250-400 ppm.
Physical maintenance covers the basics. Skim surface debris daily, brush spa walls and seats twice weekly, check and clean skimmer baskets, and backwash or clean filters as needed.
Equipment checks catch small problems before they become expensive repairs. Verify that all jets are working with proper flow, check for leaks around equipment, and ensure your spa cover fits properly.
The secret is consistency rather than intensity. Small problems caught early are much easier and cheaper to fix than major issues that develop over months of neglect.
Future-Proof Upgrades & Remodels
One of gunite’s biggest advantages is its ability to evolve with your needs. We’ve helped clients add amazing features years after their initial installation.
LED lighting systems can completely transform your spa’s ambiance. Modern color-changing LEDs are incredibly efficient and controllable from smartphone apps.
Waterfall features can be added to existing spas, though they require careful planning and skilled execution. The sound of cascading water adds a whole new dimension to your relaxation experience.
When resurfacing time comes, you can completely change your spa’s personality with different finishes. Switch from traditional plaster to exotic pebble finishes or add stunning tile work.
Automation upgrades can bring older manual systems into the smartphone age. Many existing systems can be retrofitted with modern control panels.

Quick-Fire FAQs
How long does it take to heat the spa?
With a properly sized 400,000 BTU heater, expect 30-45 minutes to bring your spa from pool temperature (typically 78-82°F) to spa temperature (100-104°F).
How many jets can I add later?
Jet placement and count are fixed at construction time. Unlike portable spas where you might be able to modify things later, gunite spa jets are permanently positioned in the shell. This is why we spend so much time during design making sure you get exactly what you want.
Gunite vs shotcrete – any real difference?
The only difference is when water gets added to the mix. Gunite arrives dry and water is added at the nozzle; shotcrete arrives pre-mixed. Performance and durability are essentially identical.
Can I use my spa year-round in New England?
Absolutely! Many of our clients use their spas more in winter than summer. There’s something magical about soaking in 104°F water while snow falls around you.
What’s the minimum size for a functional spa?
We typically recommend at least 6 feet in diameter for round spas or 6×8 feet for rectangular ones. This provides comfortable seating for 4-6 adults without feeling cramped.
Integrated Gunite Spa vs Stand-Alone Hot Tub
This question comes up in almost every consultation, and honestly, there’s no universal right answer. The choice between an integrated gunite pool with spa and a standalone hot tub depends on your specific needs, budget, and how you envision using your backyard space.
Standalone acrylic hot tubs are purpose-built for hydrotherapy. They typically feature 20-30+ jets with molded seating that’s been ergonomically designed to position your body perfectly relative to each jet.
Gunite spas take a different approach. They usually have 7-10 jets, but each one delivers significantly higher flow rates – around 15 GPM per jet compared to smaller flows in acrylic units. Think of it as fewer massage points but with more powerful therapeutic action.
From a comfort standpoint, acrylic spas have the edge in targeted therapy. Those molded seats cradle your body and hold you in the optimal position. Gunite spas offer bench seating that’s comfortable but not as precisely contoured. However, the open design gives you freedom to move around and accommodate people of different sizes more easily.
Energy efficiency is where things get interesting. Standalone spas are heavily insulated and can maintain temperature incredibly well. Integrated spas don’t hold heat as efficiently but they don’t need to heat from scratch either – they start from pool temperature (typically 78-82°F).
The cost comparison isn’t as straightforward as it might seem. A quality acrylic spa runs $8,000-15,000 installed, while adding a spa to your gunite pool starts around $25,000. However, the integrated spa becomes a permanent part of your property and adds more to your home’s value.
| Feature | Integrated Gunite Spa | Standalone Hot Tub |
|---|---|---|
| Therapy Intensity | 7-10 high-flow jets | 20-30+ precision jets |
| Energy Use | Moderate (starts from pool temp) | Lower (superior insulation) |
| Initial Cost | $25,000+ | $8,000-15,000 |
| Maintenance | Shared with pool system | Separate water management |
| Aesthetics | Seamless integration | Requires dedicated space |
| Backyard Footprint | Uses pool area efficiently | Needs separate location |
Performance & Comfort Showdown
If you’re looking for the most precise therapeutic experience, acrylic spas have advantages. The molded loungers position you exactly where the manufacturer intended, and the higher jet count means more targeted massage points.
But there’s something to be said for the flexibility of gunite spa design. You’re not locked into predetermined seating positions. Kids love the open space for playing, and adults appreciate being able to move around freely.
Insulation is where standalone spas really shine. The full foam insulation and tight-fitting covers mean they’re incredibly efficient at holding heat. An integrated spa without a quality cover can lose 10+ degrees overnight, while a well-insulated standalone unit might only drop a few degrees.
Making the Right Choice for Your Lifestyle
The decision ultimately comes down to how you plan to use your spa and what matters most to you.
Year-round soaking enthusiasts often gravitate toward standalone units because of their superior energy efficiency. If you’re planning to use your spa daily through New England winters, those insulation advantages add up on your utility bills.
Large families or frequent entertainers typically prefer the flexibility of gunite spas. The open design accommodates more people comfortably, and there’s something appealing about the seamless transition between pool and spa during parties.
Serious therapeutic needs might be better served by the precision engineering of molded acrylic seating and higher jet counts. If you’re dealing with specific injuries or conditions, the targeted therapy of a standalone unit could be more beneficial.
Budget priorities play a big role. If you’re already building a pool, the incremental cost of adding a spa often makes sense. If you just want the spa experience without a pool, standalone units have a much lower entry cost.
Aesthetic integration is where gunite spas truly excel. Nothing beats the seamless look of a properly designed integrated spa.
The truth is, we’ve seen families absolutely love both options. The key is matching the choice to your specific situation, usage patterns, and priorities.
