What are Curbless Showers?

Curbless showers, also called barrier-free or walk-in showers, are a seamless design without a divider between the bathroom and shower floor. They can accommodate people with limited mobility due to arthritis, injury, or other conditions.

Curbless showers typically have a low or no threshold, making them easy to enter and exit. They may also have grab bars, hand-held shower heads, and other features that make them safe and accessible for people with limited mobility.

Are Curbless Showers a Good Idea?

Curbless showers are a great idea for those who want an accessible and stylish shower. They can be installed in new construction or retrofitted in an existing bathroom. Curbless showers offer many benefits, including:

Increased Accessibility

Curbless showers are easier to enter and exit than traditional showers with a curb. This makes them especially beneficial for people with limited mobility or those who use a wheelchair.

Improved Safety

There’s no risk of tripping over a curb when entering or exiting a curbless shower. This helps prevent accidents and makes the bathroom safer for all users.

Enhanced Style

Curbless showers give your bathroom a modern, open, and elegant look. Their minimalist design complements most bathroom styles while creating a sense of continuity and space.

Weighing the Pros and Cons of Curbless Showers

When deciding whether to install a curbless shower, it’s important to consider both the advantages and potential drawbacks.

Pros of Curbless Showers

Space Efficiency

Curbless showers can save space in small bathrooms by eliminating the threshold or lip found in traditional showers.

Accessibility for People with Disabilities

Without a barrier, curbless showers make it easier for people with disabilities or limited mobility to access the shower area safely and comfortably.

Modern Aesthetic

Their sleek, barrier-free design gives any bathroom a clean, modern look and can make the space feel larger and more luxurious.

Cons of Curbless Showers

Higher Cost and Installation Complexity

Curbless showers are generally more expensive and more complex to install because they often require the floor to be lowered or re-sloped. Linear drains can simplify the process but still add cost compared to traditional installations.

What Is the Minimum Size for a Curbless Shower?

There’s no single standard size, but most curbless showers start at around 3’ x 3’. The minimum required size depends on your bathroom layout and the type of drain system you plan to use.

Can a Curbless Shower Be Installed in an Existing Bathroom?

Yes — but it requires careful planning. Before starting, ensure your bathroom has enough space and proper structural conditions. Consult a qualified contractor to evaluate plumbing adjustments and determine the best approach for installing a linear or center drain.

How Do You Prepare a Floor for a Curbless Shower?

Preparing the floor is a key step in the installation process:

1. Remove any existing tubs or showers.

2. Ensure the floor is flat and level.

3. In most cases, the floor must be lowered to create a flush entry that accommodates a pre-sloped shower pan.

Does a Curbless Shower Need a Linear Drain?

Not necessarily. While linear drains are popular for achieving a sleek look, several low-profile or curbless systems work with standard center or offset 4”x4” drains. The choice depends on your aesthetic goals and construction conditions.

Planning Curbless Shower Considerations for Bathroom Remodels

When remodeling your bathroom, it’s essential to plan for the technical requirements of a curbless shower.

Location of Plumbing

Plan your drain location carefully. Low-profile, foam-based center drains are easy to modify, but linear drains at the entry require precise placement of the waste pipe.

Floor Lowering

Depending on your floor structure, you may need to lower the subfloor to accommodate a curbless entry.

• For dimensional lumber (2×8 or 2×10), minor framing adjustments may suffice.

• For engineered I-beams, you’ll likely need a floor-joist lowering kit.

Drain Type

Choose between a linear drain for a high-end, modern finish or a point drain for a simpler, more cost-effective installation. Linear drains can offset their higher cost by saving labor time when floor lowering isn’t required.

Are Curbless Showers More Expensive?

Yes. Curbless showers generally cost more because they require additional planning, floor modification, and often a linear drain system. The complexity of installation makes professional help highly recommended.

How Does Water Stay in the Curbless Shower?

Proper floor slope ensures water drains efficiently within the shower area. Pre-sloped foam pans are an ideal solution, guaranteeing consistent drainage and preventing water from spilling into the rest of the bathroom.

Does Water Splash Out of a Walk-In or Curbless Shower?

A well-designed curbless shower contains water effectively. Most modern designs include glass enclosures or partial walls that keep water inside. Even so, waterproofing the entire bathroom floor is best practice — and often required by building codes.

How Do You Waterproof a Curbless Shower?

Waterproofing is essential to prevent leaks and damage. Here are the most common methods:

1. Shower Pan

A pre-sloped, waterproof shower pan (like HYDROBLOK) sits beneath the floor to direct water toward the drain. These pans have a waterproof XPS foam core, fiberglass mesh for strength, and a cement coating for tile adhesion.

2. Liner

A liner made of vinyl, PVC, or similar material covers the shower floor and walls, preventing leaks.

3. Membrane

A polyethylene or impermeable membrane is applied before tiling to ensure a fully waterproof surface.

4. Waterproof Coating

A liquid waterproof coating (latex, silicone, or similar) can be brushed or rolled onto walls and floors.

Regardless of the method, ensure all seams, corners, and drain connections are properly sealed.

How Do You Clean a Walk-In Shower?

Walk-in showers are simple to maintain.

• Clean walls and floors with mild soap and water.
