Curbless vs Low Threshold Showers: Which Is Right for Your Bathroom?

When considering safer, more accessible bathrooms, many Phoenix homeowners look at walk-in showers. Two popular options are curbless and low threshold showers. Both are designed to reduce barriers, making showering easier for seniors, those with mobility challenges, or anyone who wants a more accessible bathroom. But what are the differences? Which should you consider for your remodel? Let’s break down the details so you can make an informed choice.

What’s the Difference Between a Curbless and a Low Threshold Shower?

The main distinction is the entry height. A curbless shower has no raised edge at all—you just walk or roll right in, with the bathroom floor flowing seamlessly into the shower area. A low threshold shower has a small curb, usually 2 inches or less, providing a low step to cross but still some slight barrier.

Both styles aim to make access easier than a traditional tub or full-height shower curb, but the details can affect usability and installation.

Which Option Is Best for Wheelchair Access?

If wheelchair access is a must, curbless is the clear winner. Because there’s no curb, wheelchairs can roll right in without any obstruction. This is especially important for homeowners who use a wheelchair now or want to plan ahead for future mobility needs. Roll-in shower installation specifically uses curbless designs to make sure there’s no barrier at all.

Low threshold showers are still easier to enter than traditional ones—great for people using walkers or who need a small step—but the threshold could be a tripping hazard or blocking point for wheelchairs.

How Do They Handle Water Drainage?

One concern with any shower is keeping the water where it belongs. Curbless showers rely on careful floor sloping and well-placed drains to prevent water from escaping into the rest of the bathroom. This often means more detailed planning and professional installation. Some people also add a linear drain near the entry for extra water control.

Low threshold showers have a small curb to help contain water, so they’re a bit more forgiving if the slope isn’t perfect. They can be a good choice in older homes where it’s tough to adjust the floor structure for a full curbless conversion.

Which Is Easier to Install?

Low threshold showers are generally simpler and less invasive to install, especially in remodels where you don’t want to rework the whole bathroom floor. The small curb can be added to most existing spaces. Curbless showers usually require more work—sometimes lowering the shower area or modifying the subfloor to create a continuous surface. This is why you often see curbless options in new builds or major renovations. For more about options, see our barrier-free shower installation page.

What About Safety and Slip Resistance?

Both styles can be made very safe. Curbless showers eliminate the tripping hazard entirely, which is a huge benefit for anyone unsteady on their feet. Low threshold showers minimize the risk, but there’s still a small step to watch for. In either case, adding slip-resistant flooring, grab bars, and built-in seats further improves safety.

Do Curbless and Low Threshold Showers Look Different?

Curbless showers are popular in modern bathroom designs for their sleek, open look. They help a bathroom feel bigger and more inviting, with no visual break between the floor and shower. Low threshold showers look similar, but the small curb is visible. Some homeowners prefer the visual cue of a curb, especially in homes with multiple users.

How Do I Choose Between Them for My Home?

Consider your current and future needs. If you want maximum accessibility, especially for wheelchairs or walkers, go curbless. If you have limited space, an older home, or want an easier installation, low threshold showers are still a big improvement over traditional styles. Think about who uses the shower, your long-term plans, and your budget. A professional installer can walk you through the pros and cons specific to your bathroom.

Frequently Asked Questions

Can I convert my existing tub to a curbless shower?

Yes, but it may require modifying the bathroom floor to allow for proper drainage and a flush entry. Every project is different—older homes sometimes need more work to get the floor height right. This is something to discuss during a site visit.

Are curbless showers more prone to leaks?

When properly installed, curbless showers control water just as well as any other shower. The key is careful sloping and good drainage planning. Professional installation is recommended to avoid water escaping into the rest of the bathroom.

Is a low threshold shower enough for someone with limited mobility?

For many people, a low threshold shower provides plenty of access—especially with the addition of grab bars and a shower seat. However, if wheelchair access is a priority, curbless is usually best.

Can I get a custom design with either option?

Absolutely. Both curbless and low threshold showers can be customized to your space, style, and needs. Features like built-in seats, multiple shower heads, or glass enclosures can be included in either option.
