A truly great backyard is an entertainment hub, offering something for everyone. It’s the combination of features that creates a fun and relaxing atmosphere. A pool can have a slide for the kids, a sundeck with bubblers for lounging, and automated LED lighting to set the mood at night. We integrated all these elements and more into a recent project, creating the ultimate gunite pool in Coram. This design also included a cozy, wood-burning fire pit for cool evenings. It’s a perfect example of how thoughtful planning can transform a simple yard into the go-to destination for family and friends.
This gunite swimming pool was built in Coram, NY by Gappsi. The construction design layout, created by Giuseppe Abbrancati, consists of 10 inch walls and an 8 inch floor with 5,000 PSI dry-shot cement mix. The travertine pavers surrounding the pool were installed on 4 inches of poured concrete base and one inch of clean sand. The joints between pavers were filled with polymeric sand.
This gunite swimming pool was built to accommodate the clients wishes. It measures over 1,400 sq ft of surface area, and has a depth going from 46 to 50 inches deep. The Fiorito used for the pool coping and surrounding patio is one of the most beautiful travertine patterns selected from the Gappsi Natural Stone Showroom collection.
The pool design also incorporates a large sundeck that features a jet bubbler. It is entertaining for the kids and also serves as small water fountain feature in the center of the sundeck.
The deep end of the gunite swimming pool contains a free form stairs and bench design. The plaster finish applied on the swimming pool walls is Diamond Brite Tahiti Blue, which is a combination of Tahoe Blue and Super Blue Diamond Brite quartz finishes. 6×6 inch tiles were installed at the water line and 3×3 inch tiles were used as markers at the edges of the steps and benches.
The pool has many options starting with 3 large LED lights in the pool, one small light in the sundeck step, and the bubbler used in the sundeck has a light as well. The entire gunite swimming pool has a full automation system that works from a smart phone, allowing the customer to control the gas heater, salt chlorine generator, and Ozone system. On the outside of the pool, a wood-burning fire pit was built with firebricks and veneered with travertine. And at the deep end, a Inter-Fab X-Stream 2 pool slide was installed.

Letter From Customer
Our experience with Gappsi began in August., 2017 and it was purely by chance. My husband found their website, and dropped by their business after setting up an appointment with another pool builder down the block from them. Immediately upon walking into their place of business, he received a hospitable reception which gave him the “warm and fuzzy” feeling he likes to get when doing a business transaction. This is his indication of an honest, trustworthy company. And his intuition proved to be right. Having spent months prior doing research, we knew exactly what we wanted, a gunite pool to fit the existing landscape of our nice sized yard. The owner, Giuseppe Abbrancati, came out, took notes and pictures of our yard, and within a week, had computer generated renderings, which we were able to modify on the spot. Giuseppe and his son, Emanuele, did a phenomenal job at giving us exactly what we wanted, instead of trying to sell us on the expensive add-on features that we didn’t want. And what that enabled us to do was go bigger with our free-form design, one of the largest residential gunite pools they had done and at a very reasonable price. The only major hiccup was when their project manager had to be replaced, but once that hurdle was overcome, the newly assigned project manager, Tosh, made sure getting our pool, the gas lines, the electrical, the masonry, the sodding and landscaping were all completed in time for the opening of our pool in June, 2018. We are delighted and thrilled beyond measure at our resort style backyard. We would recommend Gappsi, a family-run business, to all!! Thanks for making our home the “destination stay-cation” of Coram, NY for our family and friends!! Everyone is in awe when they see it! – Janice Wilkinson
Frequently Asked Questions
This pool has so many features. How custom can my own pool design be? Your design can be as unique as you are. The Coram project is a great example of starting with a client’s specific vision and building from there. The process begins with your ideas, and we use tools like computer renderings to help you see exactly how it will look in your yard. This allows us to adjust details on the spot, ensuring the final design for your pool, patio, and other features is precisely what you want.
What are the benefits of using materials like travertine for the patio and a Diamond Brite finish for the pool? Material selection is about finding the right balance of beauty and durability. Travertine pavers, like the Fiorito pattern used in this project, are a popular choice because they stay cooler underfoot than many other stones, which is a huge plus on hot summer days. For the pool’s interior, a quality quartz finish like Diamond Brite provides a durable, stain-resistant surface that feels smooth and creates that beautiful, inviting water color.
How do you make sure different elements like the pool, slide, and fire pit all work together? Creating a cohesive backyard retreat comes down to thoughtful planning from the very beginning. Instead of adding features as an afterthought, we design them into the initial layout. This ensures there’s a natural flow between the swimming area, the lounge spots, and entertainment features like the fire pit. By considering how your family will use the space, we can create a unified design that is both beautiful and functional.
The post mentions smartphone automation. What does that actually do for me as a pool owner? It simplifies everything. The automation system gives you complete control over your pool’s most important functions right from your phone. You can turn on the heater before you get home, adjust the LED lights to set a mood for the evening, or check on the filtration system without having to mess with equipment. It’s all about making pool ownership more convenient and enjoyable.
A big project like this seems overwhelming. What does the process look like from start to finish? While it’s a significant undertaking, we manage the process to make it as smooth as possible for you. It starts with the design phase, where we finalize your vision. From there, our teams handle every step of the construction, from excavation and plumbing to masonry and electrical work. A dedicated project manager oversees the details and coordinates all the moving parts, ensuring the job is completed correctly and on schedule, right down to the final landscaping touches.
Key Takeaways
- Prioritize a Collaborative Design Process: Working with a designer who uses tools like computer renderings is key. This allows you to see your ideas come to life and make adjustments on the spot, ensuring the final project is exactly what you envisioned for your family.
- Think Beyond the Pool Itself: The most memorable backyards offer more than just a place to swim. By including elements like a sundeck, a fire pit for cool nights, and dynamic lighting, you create a versatile hub for both entertaining guests and quiet family relaxation.
- Invest in Quality Materials and Modern Tech: The foundation of a lasting backyard resort is high-quality construction, using materials like gunite and travertine. Pairing this with modern conveniences, such as smartphone automation for your pool systems, makes maintenance simple and gives you more time to enjoy your space.
