Top Natural Pool Companies in Portugal: How to Choose the Right Expert

Portugal is fast becoming a haven for eco-conscious living — and at the heart of that movement are natural swimming pools. But not all biopools are created equal.

Natural swimming pools are gaining popularity across Portugal for their ecological design, aesthetic integration with the landscape, and chemical-free water. But not all builders are created equal. With a growing number of companies entering the market, it’s important to understand the differences in style, quality, innovation, and service. In this guide, we’ll explore some of the most recognized names in Portugal’s natural pool industry—while offering clarity on which builder is best suited for your vision, budget, and site.

What’s the Difference Between Natural, Saltwater & Chlorine Pools

Natural swimming pools are more than a construction project — they are living systems. Designing one requires a union of ecological understanding, fluid engineering, and aesthetic sensitivity. A true expert balances all three.

Look for designers who:

Understand biological filtration (not just plumbing)
Have real experience integrating plants, stone, and structure
Can show you both clear water and clear process
Treat your land like a collaborator, not a blank slate

Experience matters — but so does philosophy. The best natural pool experts don’t just build to code — they build with care.

What Makes a Natural Pool Expert?

10 Questions to Ask Before Hiring a Pool Builder

Do you specialize in biological filtration — or just install prefabricated kits?
What types of filtration systems do you recommend and why?
What engineering do you incorporate to improve longevity?
How do you approach waterproofing and long-term maintenance?
Do you incorporate natural stone and is it secured (cemented in) for safety?
Do you build just one style (traditional, hybrid, naturalistic) of natural pool or do you have experience building others?
How many natural pools or biopools have you built?
What’s your method for ensuring water clarity without chemicals?
Can we visit or see photos of your past projects?
What makes your design philosophy unique?

The answers to these questions will reveal more than any brochure ever could.

The Top Natural Pool Builders in Portugal

Portugal is quickly becoming a European capital for eco-conscious design, and natural swimming pools are at the forefront. While there are many installers and landscapers now offering biopools, few specialize in fully integrated, plant-based systems.

Bio Piscinas

Bio Piscinas builds traditional biopools. Their team combines decades of experience with “bio‑based” solutions that prioritise sustainability and water ecology. To date, they’ve completed over 270 biological pool installations—including more than 70 for tourism and hospitality settings. The company emphasises nature‑based filtration, aquatic planting, and long‑term ecosystem performance, making them a choice for clients seeking an environmentally‑driven pool design with reliable results. Their focus in on traditional, rectangular style biopools. https://www.biopiscinas.pt/en/who-we-are/

Biotop Partner Portugal

As part of an internationally recognised network of natural pool specialists, Biotop  Partner  Portugal brings refined “Living Pool” expertise to the Portuguese market. Their systems integrate advanced biological filters with phosphate‑control technologies, allowing these pools to deliver clarity and form closer to traditional pools—but without chlorine. Their focus is on delivering high‑performance results, while ensuring the ecological health of the pool ecosystem over time. https://gb.bio.top

Swim Natural

Swim Natural is a newer entrant with a distinct angle focused on minimalist, ecological swimming environments. Their approach combines compact bio‑filtration zones and streamlined, elegant forms—appealing to homeowners seeking simplicity and efficiency with minimal maintenance. While their design language is less ornate, they excel in delivering a clean‑swimming, eco‑conscious experience for clients who prioritise function over large scale or luxury finishes. http://swimnatural.com

Oásis Biosistema

Founded in 2022 by Alberto Tassi, Oásis Biosistema is built on a passion for aquatic ecology, garden‑design and natural pools. Their process begins with a personal consultation and 3D visualisation, followed by full execution from excavation through aquatic planting and regeneration‑zone activation. They position themselves as hybrid specialists—plant‑based filtration supported by optional UV/Ozone systems—to guarantee clarity and ecosystem health. Their work suits tailored villas and regeneration projects where landscaping meets water. https://oasisbiosistema.com/en/home/

Aqua Vitae

Aqua Vitae leads the field with more than 25  years of international experience designing and building award-winning natural swimming pools, biopools and water features. What sets them apart is a proprietary ecosystem‑first methodology that blends high‑craft masonry, natural materials (stone, wood, native plants) and advanced hydraulic engineering with invisible technology (UV, drum filters, smart controls).

They also specialize in all 3 styles of natural pools (Traditional, Hybrid & Naturalistic) versus solely just one, like most natural pool companies.

With over three years of immersive training under one of the founders of the natural pool movement, they bring both tradition and innovation to every project. Their portfolio ranges from bespoke residential retreats to resort‑scale installations—each pool created to look as if it was always part of the land. Aqua Vitae’s signature is not only water clarity, but aesthetic integration, ecosystem health and lasting durability. http://aquavitaepools.com

Not all builders are equally specialized. Some companies are landscapers first, pool designers second. Vet each team for genuine biological, aesthetic and engineering knowledge, not just installation capability.
