Shower Entry Design: Curb, Threshold, or No Threshold?
Shower Curb, Threshold, or No Threshold: Which One Is Right for Your Bathroom Remodel?
When planning a bathroom remodel, the shower design always takes center stage. Tile, fixtures, and glass all get plenty of attention, but don’t forget the small detail that makes a huge difference: the shower entry.
Should you go with a traditional curb, a low threshold, or go fully curbless?
Each choice impacts style, function, and budget in its own way. Let’s pull back the curtain and break it down.
This no-threshold shower blends seamlessly into the bathroom floor, creating a clean, modern look. Paired with a freestanding tub, it’s both stylish and practical, making the space feel larger and more accessible.
Shower Curb: The Classic Choice
A shower curb is the little raised edge at the shower entrance, usually about 3–6 inches tall. It’s the most common setup, especially in older Bay Area homes.
If you’ve read our Complete Bathroom Remodel Guide for Bay Area Homes, you know that curbed showers were standard for decades, but new options are quickly catching up.
Pros:
- Keeps water neatly inside the shower.
- Works with nearly all shower doors and glass enclosures.
- Budget-friendly compared to threshold-free designs.
Cons:
- Can be a tripping hazard for kids, older adults, or anyone with mobility challenges.
- Collects soap scum and grime, making it trickier to clean.
- Less sleek than modern curbless styles.
Best for: Homeowners who want a tried-and-true option that works well in most bathrooms, especially if budget is top of mind.
A standard shower curb is the classic choice for most bathrooms. It provides a clear boundary between the shower and bathroom floor, helping to keep water contained. This remodel features marble tile and a frameless glass enclosure, combining traditional function with modern style.
Low Threshold: The In-Between Option
A threshold is the top of the shower entry. In modern remodels, many homeowners opt for a low threshold, a raised edge that’s only a couple of inches tall.
This design often pairs beautifully with upgrades like a new bathroom vanity mirror or modern tile selections, since it keeps the look clean without sacrificing function.
Pros:
- Easier to step over than a standard curb.
- Keeps most of the water inside.
- Works well with sliding glass doors and fixed panels.
Cons:
- Still a slight barrier for accessibility wheelchairs or walkers won’t clear it.
- Doesn’t have the fully seamless look of curbless.
Best for: Families who want a modern look and better accessibility than a full curb, but still want the splash protection of a little edge.
This low-threshold shower keeps a modern, streamlined feel while offering just a subtle step up from the bathroom floor. The pebble tile adds natural texture and slip resistance, while the frameless glass enclosure and built-in bench make the space feel both elegant and functional.
Curbless Shower: Sleek and Accessible
Also called zero-threshold, this design eliminates the barrier altogether. The bathroom floor flows straight into the shower, with carefully designed slopes to guide water to the drain.
Curbless showers are especially popular in accessibility-focused remodels because they’re safe, easy to use, and future-friendly.
Pros:
- Stylish, sleek, and spa-like.
- Easy access for all ages and mobility levels.
- Makes small bathrooms feel larger and more open.
- A smart choice for aging in place or multigenerational homes.
Cons:
- Requires precise planning and installation; floor slope and waterproofing are critical.
- More expensive due to extra labor and materials.
- May need linear drains or additional drainage planning to prevent water from escaping.
Best for: Homeowners who want a modern, luxurious look or who are planning ahead for long-term accessibility.
A curbless shower isn’t just sleek—it’s designed with accessibility in mind. This walk-in shower combines decorative tile insets with ADA-compliant grab bars, proving that function and style can work hand in hand.
How to Decide: Key Factors to Weigh
1. Budget
- Curb: Most affordable.
- Threshold: Mid-range.
- Curbless: Highest cost, but often worth the long-term value.
2. Accessibility
If you’re remodeling in Rossmoor or planning to age in place, a curbless or low-threshold is often the safest and most practical choice. (We cover more on planning ahead in Bath Tub Basics: Finding the Perfect Tub for Your Home).
3. Maintenance
- Curbs = more corners to clean.
- Thresholds = easier upkeep.
- Curbless = seamless look, but requires careful drainage checks.
4. Resale Value
Modern buyers are drawn to curbless showers. They signal luxury, safety, and thoughtful design, similar to how buyers light up when they see smart bathroom upgrades.
A Real-Life Example
We recently worked on a Rossmoor remodel where the homeowners wanted to update their bathroom for style and safety. Their old shower had a tall curb that became harder to step over as they got older. They chose a curbless design with a linear drain and large-format porcelain tiles. Not only did the space feel more open and modern, but they now have peace of mind knowing their shower is safer and easier to use.
It’s these little design decisions, like shower entries, that make the difference between a bathroom that simply looks nice and one that truly supports your lifestyle.
Visualizing the Difference
Think of it this way:
- Curb = High step (classic, practical, least expensive).
- Threshold = Low step (modern compromise, easier entry).
- Curbless = No step (luxurious, accessible, seamless).
Our Take
After remodeling hundreds of East Bay bathrooms, here’s what we see most often:
- Curbs are still the most common, especially for resale and budget-focused remodels.
- Low thresholds are gaining popularity among younger homeowners who want modern looks but still like a splash guard.
- Curbless showers are the show-stoppers if you’ve got the budget; they instantly elevate the entire bathroom.
✨ Pro Tip: If you’re remodeling in Rossmoor, remember you’ll often need approval from both the City of Walnut Creek and your Mutual. Accessibility upgrades like curbless showers are usually encouraged, but paperwork can take time, so plan ahead.
