When it comes to swimming pools, waterproofing is often assumed, not engineered. Builders focus on structure. Designers focus on aesthetics. Homeowners focus on features. But few ask the most fundamental question: What’s keeping the water in the pool?

Historically, pool builders have relied on concrete, tile, plaster, or thin coatings to do the job of waterproofing. These materials may resist water for a time, but they are not designed to provide true, long-term waterproofing. However builders looking for a long-term waterproofing solution are choosing Reinforced PVC (polyvinyl chloride) membranes because they are engineered specifically for the job of waterproofing.

Polyvinyl chloride, commonly known as PVC, is a widely used synthetic plastic polymer. It is versatile, durable, and relatively inexpensive, making it a popular choice for various applications, especially in construction. PVC can be found in both rigid and flexible forms, depending on the addition of plasticizers. The PVC used for waterproofing swimming pools is made flexible by the use of plasticizers. PVC is known for its smooth, non-porous surface that is resistant to water, chemicals as well as UV radiation. The use of PVC is therefore ideal for outdoor construction, plumbing and waterproofing membranes.

PVC liners and reinforced PVC membranes are the two main products made of PVC commonly used for swimming pool waterproofing. PVC liners are flexible sheets that provide a smooth, watertight surface ideal for residential pools due to their ease of installation and cost-effectiveness. Reinforced PVC membranes, on the other hand, consist of two sheets of vinyl that are laminated with a core of a polyester mesh to provide greater strength, durability and resistance to tearing without losing the elasticity and flexibility needed to adapt to different pool shapes and accommodate steps, tanning ledges, vanishing edge and beach entry pool designs etc. As a result, reinforced PVC membranes are ideal for high-end, larger commercial pools as well as residential pool construction and waterproofing.

Often misunderstood or lumped together with traditional, flexible vinyl liners, reinforced PVC membranes are an entirely different class of product that provides a true waterproofing solution and other benefits that meet the demands of performance and aesthetics required for building and renovating swimming pools.

Understanding the Difference: Reinforced PVC Membranes vs. Liners

It’s important to take the time to understand the differences between a reinforced PVC membrane versus a traditional, vinyl pool liner. While both use vinyl as a base material, the comparison between a reinforced PVC membrane and a vinyl liner is like comparing architectural-grade materials to decorative coverings — similar in base composition, however they are designed for very different applications and performance demands.

Traditional vinyl liners are made of a thinner, unsupported PVC sheet that are prefabricated to the pool shape and vacuum-formed into place. They are cost-effective and are best known for use in residential applications, especially in North America. On the other hand, reinforced PVC membranes are multi- layered systems with an internal polyester mesh, installed by certified technicians. They are welded onsite to create a seamless, robust lining with decades of durability. This product is commonly used in residential pools in Europe where it is the preferred solution for residential pool construction and waterproofing. Because of their strength, reinforced PVC membranes are frequently specified by architects and engineers for commercial pool applications, especially when waterproofing is of the utmost importance such as in elevated pools or pools with high bather loads.

The Physics of True Waterproofing

To determine the most effective pool waterproofing system, we must look at the physics of how water interacts with different materials:

Permeability: Concrete and rigid coatings are porous by nature. Over time, water will migrate through capillaries, especially under pressure.

Vapor Transmission: Even small amounts of vapor transmission can cause long-term damage behind finishes, such as blistering.

Structural Movement: Pools are dynamic structures. Ground settling, temperature expansion, and water pressure cause constant micro-movement of the pool structure.

UV and Chemical Degradation: Exposure to sunlight and pool chemicals breaks down many traditional finishes over time, compromising waterproofing integrity.

Only non-porous, flexible, and structurally independent membranes provide full waterproofing protection. Reinforced PVC membranes meet all the criteria:

1. Zero permeability to liquid and vapor
2. Resistance to hydrostatic and osmotic pressure
3. Crack-bridging flexibility
4. UV, chemical, and abrasion resistance
5. No reliance on adhesives or substrate bonding

Making the Smart Choice: A Physics-Based Evaluation

Both builders and consumers should take the time to evaluate waterproofing systems for their swimming pool by asking themselves these physics-based questions:

Reinforced PVC membranes check all the boxes — and they are backed by decades of proven use in the most demanding pool environments—from Olympic venues, hotels, resorts, water parks, high-rise elevated pools and elite residential properties.

Freeze-Thaw Resilience: A Hidden Advantage

In colder climates, swimming pools face a powerful natural stress: the freeze-thaw cycle. Water seeps into small cracks, freezes, expands, and worsens structural damage over time. Rigid coatings — including tile, plaster, or epoxy — cannot flex with this movement and often fail seasonally. Unlike other materials, reinforced PVC membranes are immune to this destructive freeze-thaw process. Their flexibility and mechanical independence from the concrete shell allow them to absorb expansion and contraction without cracking, delaminating, or weakening. This makes them ideal for pools in seasonal climates where winterization is a necessity.

Built to Move, Designed to Last

Swimming pools are not static. They expand and contract with temperature, vibrate with use, and shift subtly over time. Most finishes can’t keep up — but reinforced PVC can because they:

1/ are mechanically anchored to the shell — not bonded with adhesives that can fail

2/ bridge cracks and joints, maintaining water tightness

Additionally, reinforced PVC membranes are soft underfoot for swimmers, with optional textures for safety and aesthetics. They are also easily repairable, without the need for costly resurfacing.

It is therefore no surprise that reinforced PVC membranes are becoming the go-to specification for new construction, renovations, and commercial aquatic centers worldwide, especially since the product is offered in 60, 70 & 80mil thicknesses.

Waterproofing Is Not a Finish — It’s a Foundation

Reinforced PVC membranes are not just beautiful — they are engineered systems that deliver waterproofing as a scientific certainty, not a best guess. While other materials try to decorate or seal over a porous shell, membranes become the barrier, offering decades of reliability, even in harsh or variable environments. In today’s construction landscape, performance matters. And the physics points in one direction: reinforced PVC is the future of pool waterproofing.

In addition to the structural solution provided by these membranes, reinforced PVC membranes are now available in a wide range of new natural stone colors and textures that make them attractive to architects, designers and consumers. In fact, when builders and consumers see the variety of finishes available in reinforced PVC membranes, they are immediately drawn to the way they enhance and blend beautifully with today’s popular decking and coping treatments.

With these new stone and marble patterns, colors, and finishes, more and more hotels, athletic facilities, and wellness spas are choosing reinforced PVC membranes because they want a more attractive look that enhances the architectural design of the facility. The RENOLIT TOUCH Vanity white marble product, for example, looks amazing for large commercial spas and soaking tubs used in wellness centres, health spas, athletic facilities, and hotels.

Final Word: Waterproof First, Then Design

Waterproofing should never be an afterthought. It should be the first technical layer of decision-making, not something hidden behind tile or assumed to come with plaster.

Reinforced PVC membranes are not just a finish — they are a complete, engineered waterproofing solution. For consumers who value longevity, and for professionals who stake their reputation on reliable construction, these membranes offer a proven, physics-based path to performance and peace of mind.

As outdoor living spaces continue to evolve into true extensions of the home, homeowners are increasingly seeking luxury, function, and style in every element of their backyard designs. This year, in-pool furniture and fire features are taking center stage as two of the most in-demand trends, transforming pool decks and sun shelves into five-star resort-style environments. To get an expert perspective, we sat down with Frank Vitori of AquaBlu Mosaics, one of the most trusted voices in poolside accessories.

2 Hot Trends for 2025: In-Pool Furniture & Fire Features

Mass Adoption of Sun Shelves Sparks an In-Pool Furniture Revolution

Frank Vitori credits the meteoric rise of in-pool furniture to the widespread popularity of the sun shelf, also known as the Baja shelf. “Over 90% of modern custom inground pools are now being built with a sun shelf,” he shared. “People have come to realize that it’s not just a stylish design element—but a shallow-water hangout zone that brings comfort, safety, and versatility to families and guests.”

He points to industry innovators like Ledge Lounger, which helped define this category with their Signature Chaise. “I gotta give a lot of credit to Ledge Lounger and Chris Anderson for seeing the potential,” Vitori said. “They started with one chair at trade shows and now their products are part of nearly every luxury backyard.”

Following their example, brands like Floating Luxuries and Tenjam have entered the market with fresh takes. “Floating Luxuries came out with their Kai Collection, which is oversized, ergonomic, and super convenient to fill in place with a garden hose,” said Vitori. “Tenjam is another newer brand offering some exciting new designs for in-pool seating.”

Studio Red Rock: Cast Concrete and Built to Last

One of the most distinctive product lines comes from Studio Red Rock, which specializes in cast concrete in-pool furniture. “These are heavy-duty, commercial-grade pieces that don’t need to be filled with water because they already weigh over 160 pounds,” explained Vitori. “That permanence is a big selling point for resorts and hospitality clients. Guests can’t drag the furniture around or damage it—once it’s in place, it stays put.”

Studio Red Rock’s modern silhouettes and durable finishes are turning heads, especially in high-end commercial settings and contemporary residential pools where maintenance and visual impact are both key.

Sustainable Style Makes Waves

Sustainability is also gaining momentum in the outdoor furnishings space. European-style brands like Vondom are leading the way with eco-friendly materials, such as the Ibiza Collection made from recycled ocean plastics. “There’s no reason something sustainable has to be boring or unattractive,” said Vitori. “The Ibiza Collection is a great example of that—it’s stylish, high-quality, and it’s helping clean up the ocean. That’s a win-win.”

More and more, consumers are factoring sustainability into their design decisions, especially younger buyers who want their purchases to reflect their values.

Going Beyond the Chaise

It’s no longer just about the lounger. “We’re seeing more diversity in product offerings—rockers, modular sofas, side tables, even daybeds,” said Vitori. Ledge Lounger’s Affinity Collection is one example, offering ottomans and configurable seating that adapts to the size and shape of the sun shelf.

Some of the most underrated but impactful additions, according to Vitori, are accessories like tables with built-in ice buckets or umbrella holes. “It’s surprising how many people don’t realize that most in-pool furniture lines include coordinating side tables,” he said. “These tables often come with built-in ice bins and pre-drilled holes to accommodate umbrellas. That way, you’ve got a drink nearby, some shade overhead, and everything is cohesive.”

The Importance of Quality and Material

With in-pool furniture becoming a long-term investment, Vitori stresses the importance of selecting pieces made specifically for water use. UV resistance, structural stability, and chemical durability are essential. “There’s a lot of imitators out there now,” he warned. “Some of these cheaper versions you find online aren’t built for constant sun and chlorine exposure. They yellow, they crack, and they don’t hold up.”

Each brand has its own approach to water filling, anchoring, and material engineering. “Some have manual plugs, others you fill in the deep end. Floating Luxuries uses a hose and venting system that’s super easy to use. Every design has its pros and cons, so it’s worth talking to someone who knows the differences.”

Fire Features: A Focal Point of Year-Round Use

As homeowners look to make their outdoor spaces usable year-round, fire features are becoming a must-have. From compact fire pits to grand fire-and-water combinations, the market has expanded dramatically.

Vitori points to two standout manufacturers—Prism Hardscapes and The Outdoor Plus—as leaders in this category. “Prism Hardscapes specializes in GRFC cast concrete, offering that natural stone look. They’re sealed, color-through, and ready to ship,” he said.

In contrast, The Outdoor Plus brings more contemporary flair, with powder-coated stainless steel and hammered copper finishes. “The copper options age beautifully over time and add a real wow factor,” noted Vitori.

Innovative Designs Gaining Traction

One of the more eye-catching designs to hit the market recently is Prism Hardscapes’ Sunflower Fire Bowl. “It breaks the mold—literally. It’s a sculptural centerpiece that looks incredible on modern decks,” said Vitori.

Another highlight from Prism is the Fairmont Table, which combines teak and concrete in a hybrid fire feature perfect for coastal designs.

Ledge Lounger is also making a splash with their new Halo Fire Pit, a resin-based design that includes a hidden compartment for a compact propane tank and a rotating lid. “It’s ideal for the DIY crowd. No need to plumb gas—it’s turnkey,” said Vitori.

Fire & Water: A Visual Power Combo

The mix of fire and water is captivating, but it requires thoughtful integration. “These are usually not DIY installations,” Vitori said. “Fire and water bowls typically go on pedestals around the pool and are installed during the pool build.”

Standard models like the Cazo Bowl and Lombard are popular, but custom fabrications are on the rise. “We’re seeing more requests for 10-foot fire-and-water features, full automation, and custom pans and burner kits,” said Vitori. “Designers are pushing boundaries, and the manufacturers are stepping up to meet the demand.”

What It All Means for 2025

Fire features and in-pool furniture are more than just trendy add-ons—they’re reshaping how people live in and around their pools. “This year’s trends aren’t just about what looks good,” said Vitori. “They’re about designing for function, comfort, and usability—creating spaces that people want to live in, not just look at.”

Expect more innovation ahead as designers push for modularity, sustainability, and integration with smart systems. The modern poolscape isn’t just for summer—it’s becoming the heart of the home, all year long.
