A spa transforms an ordinary backyard or bathroom into a private wellness retreat.
Whether you want daily stress relief, muscle recovery, or simply a luxurious addition to your home — a spa delivers real, lasting benefits.
In this guide, we cover everything you need to know about spa types, benefits, and installation.
Quick Answer: The main spa types are built-in concrete spas (integrated into pools), portable spas (prefabricated, above-ground), and swim spa combos (combining swimming and hydrotherapy in one unit). Spas offer benefits including stress relief, improved circulation, better sleep, joint pain relief, and calorie burning. Installation requires careful planning, electrical work with proper GFCI protection, plumbing, and sometimes structural work — always through licensed professionals.
Key Takeaways:
- Swim spas offer two experiences in one: A full-body swimming workout plus muscle-relaxing hydrotherapy.
- Portable spas are prefabricated, not lightweight: They can be relocated, but moving them frequently is difficult.
- Warm water plus massage equals real health benefits: Stress relief, better circulation, and improved sleep are well documented.
- Joint pain relief is a standout benefit: Deep massage jets help with arthritis and chronic muscle pain.
- Installation is technical, not DIY: Electrical work, plumbing, and structural loading all need professional handling.
Types of Spas
1. Built-In Spas
Built-in spas are constructed as a permanent feature — either integrated with a swimming pool or as a standalone unit.
They are custom-built using concrete, tiled to match your pool or home design, and fitted with dedicated jets, heating, and filtration systems.
Best for: Homeowners wanting a permanent, fully customised luxury feature.

2. Portable Spas
Portable spas are prefabricated units, particularly suited to residential spaces.
These tubs sit above ground, though you can also set them into a deck for a built-in appearance.
"Portable" doesn't mean lightweight — these units are heavy. They can be relocated if needed, but frequent movement is impractical.
Best for: Homeowners who want a spa without major construction.
3. Swim Spa Combos
A swim spa combo offers the benefits of both swimming and hydrotherapy in a single space.
Swimming provides a full-body workout, while the spa section relaxes muscles and joints with massaging jets.
Swim spas typically use less energy than full-size pools, thanks to their smaller size and insulated design.
Best for: Compact spaces where you want both exercise and relaxation.

Benefits of a Spa
Stress Relief
Soaking in warm water with gentle massaging jets relieves physical, mental, and emotional stress.
Add your favourite music, and it becomes a complete sensory retreat.
Improved Skin and Circulation
Massage jets open skin pores and improve blood flow.
This enhances your skin's natural glow and supports overall health.
Better Sleep
Soaking in warm water before bed induces relaxation and can provide real relief for those struggling with sleep difficulties.
Joint Pain Relief
One of the most valued spa benefits is relief from joint pain.
Deep massage jets ease muscle cramps and joint discomfort — particularly beneficial for people with arthritis or chronic pain.
Calorie Burning
Light exercise combined with spa treatment can help burn extra calories, supporting weight management alongside relaxation.
According to the Centers for Disease Control and Prevention (CDC), warm-water immersion and hydrotherapy support muscle recovery and overall wellbeing.
How to Install a Spa
Installing a spa involves careful planning, electrical work, plumbing, and sometimes construction.
Step 1: Choose the Right Type and Location
Decide between a built-in spa, portable spa, or swim spa combo based on your space and budget.
Choose a location with good drainage, easy electrical access, and sufficient structural support — especially important for heavier portable and swim spa units.
Step 2: Plan the Electrical Work
Spas require dedicated electrical circuits to power heaters, pumps, and jets safely.
Always use a licensed electrician and ensure GFCI (ground fault) protection is installed — water and electricity are a dangerous combination.

Step 3: Set Up Plumbing and Circulation
The spa's pump circulates water through the jets, mixing it with air for that signature massaging effect.
Proper plumbing ensures efficient circulation and prevents leaks.

Step 4: Structural Preparation
For built-in spas, this involves excavation and reinforced concrete work, similar to pool construction.
For portable or swim spas, ensure the surface is level and can bear the significant weight of a filled unit.
Step 5: Test and Balance the Water
Once installed and filled, test and balance the water chemistry before use — just as you would for a swimming pool.

Frequently Asked Questions
What is the difference between a portable spa and a built-in spa?
A portable spa is a prefabricated unit that sits above ground and can be relocated, though moving it frequently is impractical. A built-in spa is a permanent structure, custom-built and integrated with a pool or as a standalone feature.
Is a swim spa combo worth it?
Yes, for compact spaces. A swim spa combo delivers both a full-body swimming workout and hydrotherapy relaxation in a single, energy-efficient unit — ideal when you don't have space for a separate pool and spa.
What are the health benefits of using a spa?
Spas provide stress relief, improved circulation, better skin health, improved sleep, joint pain relief, and can support calorie burning when combined with light exercise.
Can I install a spa myself?
Spa installation involves electrical work, plumbing, and often structural preparation that require professional expertise. Always use licensed professionals, particularly for electrical connections with GFCI protection.
Is a spa safe for people with joint pain or arthritis?
Yes, generally. Warm water and massage jets are widely used to relieve joint pain and muscle cramps, particularly benefiting people with arthritis and chronic pain. Consult a doctor for specific medical conditions.
Final Thoughts
A spa is more than a luxury feature — it's a genuine wellness investment.
Whether you choose a built-in spa, a portable unit, or a swim spa combo, the right choice depends on your space, budget, and how you plan to use it.
With proper installation and care, a spa delivers relaxation and health benefits for years to come.
