Traditional In-Ground Pools

We implement an Integrated Planning Process for every project to achieve the best quality results. Our approach to a project is to coordinate a design team that includes engineers for the topographical and structural issues, landscape designers for the aesthetics of the hardscape and softscape design, and pool/pond experts for the waterscape and hydraulic designs.  Detailed scaled drawings of the project are prepared and reviewed with the client. Sketches and 3D renderings are also provided to assist the client in visualizing how the finished site will look.

To facilitate design and consulting work with geographically dispersed clients, the Robyns use the internet and Virtual Meeting technology.  Upon acceptance of the design work, a Project Manager is assigned, permits are applied for, and the building planning is begun.  The firm uses Project software to monitor the construction of the project and ensure that it is built on time and on budget.

BioNova® Natural Swimming Pools

All natural, free of toxic chemicals. This is the swimming pool reinvented.

As a Partner with BioNova® Natural Pools and utilizing their 20+ years of experience coupled with a US Patent for the biological filtration of all-natural swimming pools/ponds, Rin Robyn Pools commands the knowledge and know-how to properly design and build these unique, sustainable watershapes.


The BioNova® system replicates the harmonious balance of a natural wetlands ecosystem in a controlled backyard setting.

Plants and beneficial microbes do the cleaning, and the result is healthy, living water in a sustainable organic backyard pool.  Interestingly, the German word for a swimming pool is Schwimmbad, which translates as "swimming bath", and the German word for a Natural Swimming Pool is Schwimmteich, which translates as "swimming pond". In English, we say Natural Swimming Pool, Natural Swimming Pond, or just NSP for short.

The first Natural Swimming Pools (NSPs) were built in the early 1980's when Europeans decided that a pool could be built to maintain the same water quality as a pristine Alpine lake. Today, NSPs are prevalent throughout Europe and are very popular in the commercial and public sectors. Some of these pools even sustain bather loads of up to 3,000 people/day while maintaining the strict European standards for water quality.

Rin Robyn Pools is using the depth of European experience to bring the all-natural, chemical-free swimming experience here to North America. For more information, contact us today!
