When you step into your shower each morning, you might not think about the small raised edge at the bottom — but that detail plays a big role in how well your bathroom functions. That edge is called the shower threshold, and while it may seem minor, it’s essential for keeping water contained, ensuring safety, and shaping the overall look of your shower.
If you’re remodeling or building a new bathroom, understanding what a shower threshold is — and the options available — can make a big difference in performance and design.
What Exactly Is a Shower Threshold?
A shower threshold is the slightly raised barrier at the entrance of your shower. It’s typically made of tile, stone, or another waterproof material and serves three main purposes:
Containment: Keeps water inside the shower area.
Support: Provides a stable base for doors or glass enclosures.
Transition: Creates a clean boundary between wet and dry areas of the bathroom.
In short, it’s the unsung hero of your bathroom remodel. Without it, you’d likely be mopping up water after every shower.
Common Types of Shower Thresholds
When planning your remodel, you’ll find there are several threshold styles to choose from, each with its pros and cons.
1. Standard Raised Threshold
Look: About 3–6 inches high, common in traditional showers.
Best for: Bathrooms with framed or frameless glass doors.
Pros: Excellent water containment, reliable, and versatile.
Cons: Not accessible for wheelchairs or people with mobility issues.
2. Low-Profile Threshold
Look: A slimmer curb, usually 1–3 inches high.
Best for: Sleek, modern showers with sliding or hinged glass.
Pros: Easier to step over, clean-lined appearance.
Cons: Slightly less water containment compared to higher thresholds.
3. Curbless (Zero-Threshold) Showers
Look: No raised edge — the floor flows seamlessly into the shower.
Best for: Barrier-free, accessible, or luxury spa-style bathrooms.
Pros: Wheelchair-friendly, modern aesthetic, very safe.
Cons: Requires precise sloping and drainage — more expensive installation.

Materials for Shower Thresholds
The threshold material should match both your shower style and your budget. Popular choices include:
Tile: Affordable, versatile, but grout requires maintenance.
Stone (marble, granite, quartz): Luxurious and durable, adds elegance.
Solid-surface materials: Seamless and low-maintenance, often used in modern bathrooms.
Acrylic or fiberglass (prefab bases): Budget-friendly, though less customizable.
👉 For homeowners upgrading the whole bathroom, coordinating with countertops or flooring can create a cohesive look.
Safety Considerations
Shower thresholds aren’t just about design. They’re also about safety.
Slip resistance: Choose materials with texture or pair them with slip-resistant flooring.
Height: A very high threshold can be a tripping hazard, especially for kids or seniors.
Accessibility: If mobility is a concern, low-profile or curbless thresholds are worth considering.
Safety should be part of your planning from the very beginning.
Design Tips
Want your threshold to look intentional rather than just functional? Try these ideas:
Coordinate with countertops: Using the same stone ties the design together.
Add contrast: A darker or lighter threshold can create a striking visual border.
Extend into niches or shelves: Using the same material for thresholds and accents creates cohesion.
The right threshold becomes part of the bathroom’s overall design story.
Costs and Installation
The cost of a shower threshold depends on material and labor:
Prefab bases with thresholds: $200–$800.
Custom tile or stone thresholds: $500–$1,500+.
Keep in mind, installation is critical. A poorly built threshold can lead to leaks, water damage, and costly repairs. Always hire a professional who knows how to slope the shower pan correctly and seal the threshold for long-term durability.
