Founded in 1970, Tieleman Pool Technology, began as a family-run business specializing in hydrotherapy. In the early days, the company focused on addressing the needs of patients requiring low-impact movement to enhance their rehabilitation. Marijn Tieleman, who eventually took over the company with his cousin about a decade ago, reflects on the company’s origins: “There was a lot of demand for movable floors and different heights. In the ’70s, we were experimenting a lot with trial and error. The focus was on creating solutions for hydrotherapy, but as we advanced, the technology began to catch on for other applications.”
Tieleman recalls, “We transitioned from a purely medical focus to exploring private residential markets. Our hydrotherapy systems had proven their reliability and efficiency in hospitals, so we wondered if we could adapt this technology for home use.” This shift was not without challenges, but it opened up new possibilities for residential applications, leading to the development of movable pool floors that could transform private backyards.

The Technology Behind Movable Pool Floors
Movable pool floor technology, once a niche innovation, is now making waves in the residential market. Tieleman explains, “The technology involves a frame made of high-grade 316 stainless steel, equipped with a hydraulic system. This system, which uses water hydraulics rather than oil, allows the floor to adjust seamlessly to various depths.” The floor operates as a floating platform, which can be raised or lowered via a touch screen control panel. This flexibility enables homeowners to customize their pool’s depth, creating multi-use spaces that can transition from a swimming pool to a functional area for other activities.

Market Appeal
The appeal of a movable pool floor lies in its versatility. Tieleman describes how this technology can transform a backyard: “If you have limited space, a movable floor allows you to use your pool area for different purposes. For example, you can have a pool that doubles as an entertainment space. When the floor is raised, it becomes a level surface suitable for placing furniture or hosting events.” This adaptability is particularly valuable for those with smaller yards or who wish to maximize the functionality of their outdoor spaces.
The speed at which the floor adjusts is one of its most impressive features. “Typically, it takes about 4 to 5 minutes to raise or lower the pool floor,” Tieleman says. This rapid adjustment allows homeowners to transform the pool area quickly, making it ideal for spontaneous gatherings or activities. For smaller changes in depth, the adjustment can be even faster, offering a high degree of flexibility.
When it comes to depth, the possibilities are virtually limitless. Tieleman notes, “The depths we can build these pools are endless, really. We’ve actually built a couple of diving pits that go all the way down to 50, 60 feet for commercial diver training. We can’t use the same cylinder we normally do, of course; it has a little different pulley system on it. But basically, there’s no limitations.”

When considering a movable pool floor, pricing inevitably becomes a factor that would preclude this as a product you’re bound to see everywhere. Tieleman explains, “Pricing really depends on how many options you wish to do. But if you have some stairs or some odd shapes, or unique features it can cost more. I would guess in between 150K to endless, really. But for entry-level, around $150,000. That’s around where you start off with a movable floor,” said Tieleman.
One of the main advantages of Tieleman’s system is its durability and ease of maintenance. “Our systems are built to withstand heavy use,” Tieleman notes. “We use chlorine and salt-resistant materials, and maintenance is minimal. We typically perform annual checks and repairs if needed, ensuring the system remains in top condition.” This emphasis on longevity and reliability adds to the appeal of movable pool floors, making them a practical investment for homeowners.
The design options for these systems are extensive. Tieleman elaborates, “Customization is a significant part of our offering. We’ve created everything from movable jacuzzis and swim-out benches to pool covers with integrated lighting. The possibilities are endless, limited only by the homeowner’s imagination.”
A Recent Case Study
One standout example of Tieleman Pool Technology’s innovation is an ongoing project in the Bahamas. Tieleman shares, “In this project, we designed a pool with two movable floors, each capable of reaching different depths. It was an ambitious undertaking that required meticulous planning and engineering.” The dual-floor system allowed the homeowners to adjust the pool’s depth for various activities, from swimming to hosting large events.

Tieleman elaborates, “The complexity of the project came from ensuring the two floors operated seamlessly together. Each floor needed to function independently while maintaining precise alignment. Our team worked closely with the clients to tailor the system to their specific needs and ensure it met all safety and operational standards.” The project involved integrating advanced hydraulic systems and custom controls, reflecting the high level of sophistication that Tieleman Pool Technology brings to its designs.

This unique movable pool is a prime example demonstrating the potential of movable pool floors in creating unique and versatile outdoor environments. “The feedback from the clients has been overwhelmingly positive,” Tieleman says. “They were thrilled with the flexibility the system offered. It allowed them to have a stunning pool that could adapt to their needs, whether they were hosting a party or enjoying a quiet swim.”
European Design Trend Becoming More Popular With U.S. Builders
As the technology gains traction, its adoption in the U.S. market is growing. Tieleman notes, “In Europe, the response has been phenomenal. In the U.S., it’s starting to catch on as builders and homeowners become more familiar with the technology. The key challenge here is educating the market about how it works and its benefits.”
The trend towards movable pool floors reflects a broader shift in outdoor living, where functionality and aesthetics converge. Tieleman highlights, “People are looking for ways to make their outdoor spaces more versatile. A movable pool floor offers a unique solution, allowing for a customizable environment that can adapt to various needs.”
As movable pool floors become more popular, the notion of keeping up with the Joneses is evolving. It’s no longer just about having a pool in your backyard; it’s about having one that remains hidden until you want to reveal it. This innovation represents a new frontier in outdoor living, where the ordinary becomes extraordinary through advanced technology and thoughtful design.
In an era where backyard spaces are increasingly valued for their multifunctionality, a pool that can seamlessly transition between different uses may well become the ultimate status symbol. For homeowners looking to elevate their outdoor living experience, embracing movable pool floor technology might just be the next big leap.
