The Luxury Feature Redefining Backyard Design

Have you ever dreamed of a pool that disappears into your patio at the push of a button?

What if your pool could be shallow one moment, deep the next—or completely hidden from view?

In this article, you’ll learn how movable floor pools—also known as hidden or disappearing pools—are transforming modern backyard design.

We’ll explore what they are, how they work, what they cost, who they’re best for, and what you need to know if you’re considering one for your home.

What Is a Movable Floor or Disappearing Pool?

A movable floor pool is a luxury swimming pool that features a mechanically adjustable floor, which raises and lowers on demand. Also referred to as a disappearing pool or hidden pool, this design was originally engineered for high-end resorts and wellness centers. Today, it’s being integrated into elite residential properties around the world.

At its core, the system uses a hydraulic mechanism connected to a buoyancy-supported steel frame. When activated, the system gently lifts or lowers the floor to the desired depth. Once fully raised, the floor locks into place with a precision gap of less than 5/16 of an inch, creating a completely flat, walkable surface.  Other configurations do not involve submerging the floor, but rather sliding a surface deck as well.

...And this isn’t just a visual effect

The raised surface is engineered to hold heavy loads, allowing you to host events, add outdoor furniture, or even dance right on top of your pool.

A movable floor pool gives you a full-depth pool, a shallow splash zone, or a solid patio—all in one footprint.

How Do Movable Floor Pools Work?

Movable floor pools operate via a custom hydraulic lift system anchored into a reinforced concrete subfloor beneath the pool basin. This subfloor sits deeper than the visible deck surface and supports the system’s structural and buoyancy mechanisms.

Cables and floats connect the movable floor to the hydraulic frame. When you activate the system, the floor moves vertically to the preset depth—or rises completely to become flush with the surrounding deck, hiding the water entirely.

Each system is custom-designed to suit the pool's shape, features, and site conditions. Even the lighting must be planned precisely to ensure it doesn’t obstruct floor movement or create a safety risk.

Control is managed through a password-protected automation panel, typically mounted on a nearby wall or column with clear sightlines to the pool. This ensures you can confirm the surface is clear of objects before activation.

Material selection is critical:

The pool floor must be built with materials proven to withstand submersion, temperature shifts, and constant load.

That’s why discussions around expansion behavior, finishes, and structural materials should take place early, alongside the architect, builder, and pool engineer.

With a single button press, your backyard transforms from a solid patio to a fully functional pool.

What Are the Benefits of a Movable Floor Pool?

Movable floor pools offer more than luxury—they deliver flexibility, safety, and smart design in one system. Here’s how:

Maximize Space in a Multi-Use Backyard

For many high-end homeowners—especially those with limited urban lots—space is precious. With a movable floor pool, you no longer have to choose between a patio and a pool; you can enjoy both.

When not in use, the pool becomes a flat, secure surface perfect for entertaining, lounging, or even extra parking.

Enhanced Safety for Families and Pets

Worried about open water around kids or pets? These pools solve that.

You can set the floor at just a few inches deep for playtime, or raise it entirely to prevent access. Combined with a password-locked control panel, only authorized users can operate the system.

When the pool is closed, it’s fully sealed, offering peace of mind and maximum safety.

All-Season Functionality

Movable floors are designed for all climates. Heated deck surfaces prevent ice and snow accumulation, making your outdoor space usable year-round. No need for a cover or winter prep.

Whether it’s 95° or snowing, your pool adapts with the seasons.

Seamless Aesthetic Integration

These pools are custom-finished to match your patio materials—think stone, porcelain pavers, or wood-look tiles rated for submerged use.

The result? A luxurious, invisible pool surface that blends perfectly with your backyard design.

What Does a Movable Floor Pool Cost?

Movable floor pools are a premium investment—these aren’t modular kits or quick upgrades. They’re custom-built systems that require precision engineering and extensive planning.

Most systems start around $150,000 and can exceed $300,000—not including the cost of the pool itself.

What Factors Influence the Cost?

Several elements impact the total investment:

• Pool Size & Shape
  Larger or uniquely shaped pools (with baja shelves, benches, or curved edges) require more complex mechanics and framing.
  
  
• Material Selection
  Submerged-rated materials like natural stone or high-end tile will add both material and installation costs.
  
  
• Hydraulic Engineering & Site Conditions
  Soil type, slope, and site access affect how the system is designed and installed.
  
  
  This cannot be overlooked—poor planning can cause leveling issues or structural failure.
  
  
  
• Automation & Controls
  Integration with smart home systems, mobile apps, or security panels adds convenience and cost.
  
  
• Location & Labor Access
  Tight access or challenging terrain may require specialized installation equipment, which can increase labor time.
  
  
• Waterproofing and Circulation Systems
  Proper circulation, facilitated by advanced mechanical systems, ensures adequate water flow, optimal energy efficiency, and long-term durability. In particular, drainage and waterproofing are crucial for protecting your investment and maintaining consistent performance.
  
  

A fully completed luxury movable pool project often ranges between $400,000 and $700,000+.

Why Transparency Matters, many homeowners are unaware of the extensive coordination and engineering required for these systems.

Discussing goals, site conditions, and budget early with your pool builder, architect, and hydraulic team will save time, money, and avoid redesigns.

Movable floor pools are not for everyone, but for the right homeowner, they’re unmatched in design and performance.

What to Expect During Design and Installation

Planning is everything. These systems require zero tolerance for error—the pool vessel is engineered to house all mechanics below the floor.

Access panels for maintenance are integrated into the floor frame, allowing for safe and routine servicing.

Expect close collaboration between:

• The system manufacturer
• Installation team
• Structural engineers
• The pool builder
• Architects and designers

Movable floor systems require precise engineering and early collaboration between all trades.
