Are Floating Stairs Safe? What to Know Before Installing Them

The short answer? Yes — floating stairs can absolutely be safe. But (and this is a big but) their safety depends on a few non-negotiables: proper installation, high-quality materials, and following building codes.

And spoiler alert — railings are a huge part of that equation.

When floating stairs are done right, they can be just as safe as any traditional staircase. But when shortcuts happen — like skipping a railing, using the wrong materials, or ignoring code — that’s when things get risky. Nobody wants their gorgeous, modern staircase turning into a hazard zone.

So if you’re dreaming of adding floating stairs to your home, just know this: railings aren’t just there for looks. They play a huge role in keeping your stairs safe, sturdy, and up to code.

What Are Floating Stairs, Anyway?

Floating stairs (sometimes called cantilever stairs, modern stairs, or open riser stairs) are exactly what they sound like — a staircase designed to look like the steps are literally floating in mid-air.

It’s all about creating that sleek, open feel. And to get that look, floating stairs leave out a few things you’d normally see on a traditional staircase — like the bulky side supports (called stringers) or the vertical piece between each step (called risers). Instead, the treads are often anchored into a wall or supported by a hidden metal frame.

That’s how you get that airy, architectural vibe everyone loves.

You’ll usually see floating stairs in modern homes, open-concept layouts, or stylish lofts — basically any space where homeowners want to make a bold design statement.

But here’s the thing: as stunning as floating stairs are, they can also feel… well, a little naked without a railing. That sleek, minimal look is part of the appeal — but railings bring balance. They ground the design, add structure, and most importantly? They keep everyone safe while still letting those floating vibes shine.

The Big Safety Risks of Floating Stairs (That Nobody Talks About Enough)

Let’s get real for a second — floating stairs look incredible, but they also come with some very real safety concerns that often get overlooked in all those dreamy Pinterest photos.

First up? Falls and slips. Since floating stairs usually skip the risers (those vertical pieces between steps), there’s just... more open space. And while that open look is part of the charm, it can also throw off depth perception — especially for kids, pets, or anyone unfamiliar with the stairs. Miss a step, lose your balance, or trip on slick treads? You’re looking at a pretty rough landing.

Speaking of kids and pets — floating stairs without any sort of railing or barrier can feel like a built-in jungle gym for little climbers or a dangerous gap for curious pets. It’s not just about falling down the stairs — it’s about slipping through them.

And then there’s the DIY danger zone. Floating stairs aren’t a weekend project. They require precise engineering, proper anchoring, and the right materials. Cutting corners on the structure itself is a huge risk — but skipping the railing? That’s one of the biggest mistakes homeowners (or even inexperienced builders) can make.

Because here’s the thing: railings aren’t just there for looks. They’re a critical safety feature that protects your family, your guests, and yes, your pets too. Leaving them out isn’t edgy or cool — it’s just unsafe.

Are Floating Stairs Up to Code? (Here’s Where Railings Come In)

This is the part most homeowners don’t realize until after they’ve fallen in love with the idea of floating stairs: building codes have a lot to say about them.

And yep — most of those codes are about safety. (Translation: railings are non-negotiable.)

Let’s break it down.

Riser Gap Rules

Most building codes — including the International Residential Code (IRC), which New Jersey follows — say that the space between stair treads (aka the open part where risers would normally go) can’t allow a 4-inch sphere to pass through. Why? Because it’s all about preventing small kids (or pets!) from slipping through.

Floating stairs with huge open gaps? Not gonna fly.

Railing Height + Spacing Requirements

On top of riser rules, floating stairs have to meet the same railing requirements as any other stairs:

• Railings must be between 34-38 inches high (measured from the front of the tread).

• Any balusters (those vertical or horizontal pieces in the railing) also need to be spaced so a 4-inch sphere can’t pass through.

• In most cases, a handrail is required on at least one side — often both if the stairs are wide enough or not against a wall.

NJ Building Code Specifics

New Jersey doesn’t play around when it comes to stair safety. Floating stairs in NJ homes need to meet both the IRC standards and any local township rules — which can sometimes be even stricter.

Bottom line? Floating stairs without railings aren’t just unsafe... they’re usually illegal.

Why Code Expects Railings on Floating Stairs

Floating stairs already push design boundaries by removing risers and visible support. Railings are what keep them grounded (pun intended). They provide balance, support, and structure — all while protecting everyone who uses them.

If you’re investing in floating stairs, your railing isn’t an afterthought. It’s part of the whole safety system — and honestly, it’s what makes that jaw-dropping design feel complete.

Floating Stairs Pros & Cons (And How Railings Balance Both)

Like anything in home design, floating stairs come with their own list of perks and trade-offs. Let’s take a look.

Pros: Why Homeowners Love Floating Stairs

• Modern, sleek, open feel — Nothing else looks quite like them.

• Architectural wow-factor — They’re a total statement piece that adds instant drama and style.

• Light & airy design — Perfect for small spaces or open floor plans.

Cons: What You Need to Think About First

• Higher cost — Floating stairs usually require custom fabrication and expert installation.

• Safety concerns — Especially without risers or railings, these stairs need thoughtful planning to keep everyone safe.

• Railings aren’t optional — they’re essential — This is the part most Pinterest boards leave out. Floating stairs look light and minimalist... but behind the scenes, it’s the railing system doing a ton of safety work.

The truth is, railings aren’t there to ruin your floating stair dreams — they’re there to make sure you (and everyone you love) can enjoy them for years to come.

Floating Stair Railing Ideas We Absolutely Love

When it comes to floating stairs, the right railing isn’t just about safety — it’s about style, too. And lucky for homeowners, modern railings can do both effortlessly.

Now look — you’ve probably seen a lot of floating stair inspo online featuring glass railings.

They’re trendy, sure… but they’re also high-maintenance, fingerprint-prone, and not exactly cozy or warm.

That’s why we love railing designs that bring together the best of both worlds: natural wood details that match your stair treads, paired with sleek metal bars for that modern edge.

Here’s what we’re loving (and installing!) right now:

Warm Wood Rails + Posts

Floating stairs already feel minimal — adding stained or painted wood rails and posts helps ground the design and tie everything together. Plus, matching the stair treads? Chef’s kiss. Total custom, built-in look.

Matching Wood & Metal Railings

Sleek Metal Bars in Ash Gray or Satin Black

Instead of chunky balusters or overly ornate designs, thin metal bars keep things clean and streamlined. Ash gray blends beautifully with lighter woods for a soft modern feel, while satin black adds bold contrast and drama.

Horizontal or Vertical Metal Bar Designs

Want that ultra-modern, horizontal look? We do that. Prefer a more classic vertical bar layout? Got you covered. Either style works beautifully with floating stairs — it all depends on the vibe you’re going for.

Custom Wall-Mounted Wood Handrails

Sometimes floating stairs need a little extra balance support along the wall — but without taking away from the look. A simple, custom wood wall rail (stained or painted) adds subtle safety.

How Much Do Floating Stairs Cost? (And Why Railings Matter More Than You Think)

Let’s be upfront — floating stairs are a statement piece. And like most things that turn heads in your home, they come with an investment price tag. But what exactly are you paying for? And how do railings impact the total cost?

Let’s break it all down.

What Impacts the Cost of Floating Stairs?

Several things influence how much floating stairs will cost for your home:

• The Material of the Treads → Most homeowners go with solid wood treads, and red oak is a popular choice. It’s durable, takes stain beautifully, and pairs perfectly with wood railings and posts.

• Your Railing Design → This is huge. Railings for floating stairs aren’t basic or off-the-shelf. Metal railings (in ash gray or satin black) get custom-fabricated, and wood posts or rails are made to match your stair treads.

• The Layout of Your Stairs → Straight stairs are the most budget-friendly. Add turns, landings, or special framing? The price goes up.

• Installation & Engineering → Floating stairs need serious structural support hidden behind all that sleek design. Expert labor and code compliance are non-negotiable.

Realistic Price Ranges for Floating Stairs with Red Oak Treads & Metal Railings

Why Are Railings Priced Separately?

In most floating stair projects, the railing system is priced on its own because it’s fully customized. This isn’t cookie-cutter work — your railing has to fit the space exactly, meet safety codes, and tie the whole design together.

And let’s be real — railings are what turn floating stairs from “cool” to complete.

They’re not just there for safety (though that’s reason enough). They add balance, style, and structure to the entire staircase.

Final Takeaway: Are Floating Stairs Safe? They Can Be — With The Right Plan.

At the end of the day, floating stairs can absolutely be safe — but only when every part of the design and installation is done carefully and correctly.

These stairs aren’t just about looks (even though they totally deliver on that front). They need proper engineering, quality materials, and yes — safety features like railings — to make sure they work for real life, not just for a photo shoot.

If you’re planning floating stairs in your home, the smartest thing you can do is plan for safety from the start. Talk with your builder. Know your local codes. Think through how kids, pets, or guests will use the space.
