Curbless and low-threshold showers both remove the tall step of a traditional tub or shower curb, but they are not the same thing. A curbless shower has no raised edge at all, while a low-threshold shower keeps a small step of about 2 to 4 inches. For Oklahoma homeowners planning a safer bathroom, the right choice comes down to mobility needs, bathroom layout, and budget.
Both options are popular with Oklahoma City area homeowners who want easier access without giving up style, and both can usually be installed in the footprint of an existing tub or shower. Here is how they compare.

What Is a Curbless Shower?
A curbless shower, also called a barrier-free or zero-entry shower, has no raised edge between the bathroom floor and the shower floor. The floor slopes gently toward the drain, so water stays contained without a curb.
You can walk or roll straight in, which makes curbless showers the most accessible option available. They are a common choice for homeowners who use a wheelchair or walker, and for anyone planning to age in place in their Oklahoma home.

What Is a Low-Threshold Shower?
A low-threshold shower has a small raised edge, usually 2 to 4 inches high, instead of the 6-inch or taller curb found on many traditional showers. You still step over an edge, but it is a much shorter and easier step.
Low-threshold showers generally cost less than fully curbless designs because the bathroom floor rarely needs to be recessed or re-sloped. For many homeowners, they balance safety, style, and budget.

Curbless vs. Low-Threshold Showers: Side-by-Side Comparison
| Curbless (Barrier-Free) | Low-Threshold | |
| Entry height | None, floor-level entry | Small step of about 2 to 4 inches |
| Wheelchair access | Yes, true roll-in entry | Limited; not roll-in |
| Floor modifications | Often requires recessing or re-sloping the floor | Rarely requires floor work |
| Water containment | Relies on proper slope and drain placement | Curb helps keep water inside |
| Typical cost | Higher, due to floor work | Lower, simpler installation |
| Best for | Maximum accessibility and aging in place | Safer bathing on a smaller budget |
Which Option Fits Your Oklahoma Home?
The right answer depends on your home and your household. A few factors that matter for Oklahoma City metro homeowners:
- Foundation type: many Oklahoma homes sit on concrete slabs. Creating a true curbless entry on a slab can involve recessing the floor, which adds labor. A low-threshold shower usually avoids that work.
- Bathroom size: curbless showers use continuous flooring, which can make a small bathroom feel larger and more open.
- Mobility equipment: if anyone in the home uses a wheelchair or walker, a curbless roll-in entry is the safer long-term choice.
- Household plans: if you plan to age in place, a curbless shower installed now removes the need for a second project later.
What Does Each Option Cost in Oklahoma?
Final pricing depends on the size of the space, the materials you choose, and any plumbing changes, but curbless conversions typically sit at the higher end because of the floor work involved. Our tub to shower conversion cost guide puts curbless and barrier-free conversions between $5,000 and $12,000 in the Oklahoma City metro, while conversions that keep a low curb usually cost less.

Safety Features to Pair With Either Option
Entry height is only part of a safer shower. Our low-barrier and barrier-free shower systems can be configured with features that make daily bathing safer and more comfortable:
- Grab bars placed where you actually enter, exit, and turn
- Built-in or fold-down seating for seated bathing
- Slip-resistant flooring for better footing on wet surfaces
- Handheld shower wands for easier rinsing while seated
- Anti-scald valves that keep water temperature steady
If you are weighing a full upgrade, our walk-in shower options cover both entry styles in a range of wall finishes and fixtures.
Frequently Asked Questions
Is a curbless shower the same as a barrier-free shower?
Yes. Curbless, barrier-free, and zero-entry are three names for the same design: a shower with no raised edge between the bathroom floor and the shower floor.
Can a curbless shower be installed in an existing Oklahoma home?
In most cases, yes. Many curbless showers replace an existing tub or shower in the same footprint. Homes on concrete slabs, which are common across the Oklahoma City metro, may need the floor recessed or re-sloped, and your installer can confirm what your bathroom requires during an in-home evaluation.
Do curbless showers leak water onto the bathroom floor?
Not when they are designed correctly. A properly built curbless shower uses floor slope, drain placement, and sometimes a weighted shower curtain or glass panel to keep water inside the wet zone. Correct design is the reason professional installation matters for curbless projects.
How much does a curbless shower cost in Oklahoma City?
Curbless and barrier-free conversions in the Oklahoma City metro typically range from $5,000 to $12,000 depending on the space, materials, and floor work required. BathPlanet of Oklahoma provides a guaranteed price that stays valid for 12 months after your complimentary consultation.
Are low-threshold showers safer than standard showers?
A lower step reduces trip risk compared with a tall shower curb or tub wall, and pairing a low-threshold entry with grab bars, seating, and slip-resistant flooring makes the shower safer still. For anyone with significant mobility limits, a fully curbless entry is the safer option.
Does BathPlanet of Oklahoma install curbless showers?
Yes. We install low-barrier and barrier-free shower systems across the Oklahoma City, Tulsa, and Enid areas, with showrooms in Yukon, Enid, and Sand Springs. Qualifying installations are backed by a lifetime warranty on parts and labor.
