What Is a Walk-In Shower?
A walk-in shower is a modern, accessible alternative to traditional high-walled bathtubs, designed for easier entry and a more open bathroom layout. Unlike prefabricated stalls, these are typically custom-built systems that integrate specialized drainage, waterproofing, and fixture layouts directly into your home’s structure. In the Central Valley, these systems are a premier choice for homeowners looking to improve accessibility and modernize aging bathrooms.
Walk-In vs. Curbless: Choosing the Right Entry
While the terms are often used interchangeably, there is a significant mechanical difference between a standard walk-in and a true curbless design:
- Walk-In Showers: Broadly defined as any showering space you can enter without stepping over the high wall of a bathtub. These typically feature a low-threshold curb (3 to 6 inches) to contain water while providing significantly easier access than a tub-shower combo.
- Curbless (Zero-Threshold) Showers: The “gold standard” for accessibility, this design eliminates the entry barrier entirely. The bathroom floor flows seamlessly into the shower, which requires specialized slope engineering and high-capacity drainage to prevent water from migrating into the rest of the bathroom.
Trending Walk-In Shower Styles
While we handle the mechanical rough-in and waterproofing, your choice of design dictates the specific plumbing configuration required for your Clovis home.
| Shower Style | Best For… | Key Plumbing Requirement |
| Open Minimalist | Modern, spacious bathrooms. | Precise floor pitching and high-capacity linear drains. |
| Glass-Enclosed | Containing steam and water spray. | Strategic valve placement to avoid spraying the door. |
| ADA-Inspired | Aging in place and accessibility. | Barrier-free entry, grab bar reinforcement, and handheld sprayers. |
Local Insight: Slab vs. Crawlspace Foundations
In Clovis and the surrounding Central Valley, the feasibility and cost of your shower design depend heavily on your home’s foundation.
Concrete Slab-on-Grade (Common in NE Clovis)
Most modern developments sit on concrete slabs. To achieve a true curbless entry, we must precision-cut and trench the existing concrete to lower the drain assembly and create the necessary slope. This requires specialized equipment and careful execution to avoid damaging post-tension cables or existing utility lines.
Raised Foundations & Crawlspaces (Common in “Old Town”)
Homes with crawlspaces offer more flexibility for drain relocation. While the plumbing is easier to access, these projects often reveal aging cast iron or galvanized piping that should be replaced to ensure the long-term integrity of your new shower. During the transition, we also assess the floor joists to ensure they can support the weight of new tile or heavy luxury fixtures.
The Anatomy of a Reliable Installation
A walk-in shower is only as good as the systems hidden behind the tile. As licensed C-36 plumbing contractors, we focus on the “3-Point Integrity Check”:
- Drainage & Slope: We ensure the subfloor is modified to maintain a proper drainage pitch (typically 1/4” per foot) to prevent standing water and back-ups.
- Waterproofing & Membranes: We install integrated waterproof membranes behind walls and under the base to protect your home’s framing from moisture intrusion, soft spots, and mold.
- High-Performance Valves: For luxury walk-in designs, we often prep the system with 3/4” piping to support high-demand fixtures like rain heads and body sprays.
Key Plumbing & Design Considerations
1. The “Scalability” Factor: Pressure & Flow
Because many walk-in showers in Clovis include luxury multi-outlet systems—such as rain heads, handhelds, and body sprays—the underlying pipe sizing is critical to daily comfort.
- Supply Line Sizing: We often recommend 3/4” supply lines for high-demand systems to ensure consistent pressure throughout the shower experience.
- Hard Water Impact: This is especially important in the Clovis area, where hard water minerals can lead to internal pipe scaling and reduced flow over time.
Pro Tip: For showers with multiple fixtures, we recommend installing a thermostatic mixing valve. Unlike standard valves, these allow you to set a precise temperature and maintain it even when other water-connected appliances, like a dishwasher or washing machine, are running elsewhere in the home.
2. Local Permitting & Compliance
Professional shower installation in Clovis is a “permitted” event. Because walk-in and curbless designs involve structural modifications to your home’s drainage and waste systems, professional oversight is required to protect your property value.
- Permits & Inspections: We handle all coordination with the City of Clovis Building Division to ensure your project meets local safety requirements and passes all necessary inspections.
- Code Compliance: Our installations strictly adhere to the standards set by the International Association of Plumbing and Mechanical Officials (IAPMO). This ensures that every aspect of your project—from the drainage pitch to the venting layout—is executed according to the highest industry safety codes.+1
3. Maintenance for Longevity
A custom shower is a major investment. To prevent the scale buildup that typically stiffens shower valves and clogs showerheads in the Central Valley, we utilize specialized, pressure-balanced valves and recommend regular maintenance.
- Fixture Calibration: For multi-outlet luxury systems, ensure showerheads are cleaned regularly to remove mineral deposits that can restrict water flow and affect pressure.
- Hard Water Defense: Mineral buildup from local hard water can shorten the life of your fixtures. We install scale-resistant, pressure-balanced valves to maintain consistent temperature and smooth handle operation.
- Regular Drain Care: To ensure your shower continues to drain properly, we recommend periodic drain cleaning to remove hair and soap scum before they cause a backup.
- Sealant Inspection: Periodically check the silicone and grout lines around the shower base and glass panels. Maintaining a watertight seal is critical for protecting the surrounding bathroom structure from hidden moisture damage.

Frequently Asked Questions About Walk-In Showers
What is a walk-in shower?
A walk-in shower is a shower design with open entry or a low-threshold entry instead of a traditional tub wall or high curb. Many walk-in showers use glass panels, tiled walls, and custom drainage layouts to create a more open and accessible bathroom design.
Is a walk-in shower the same as a curbless shower?
Not always. A walk-in shower refers to the overall style of shower with easy entry, while a curbless shower is a specific type of walk-in shower with no raised threshold at all. Some walk-in showers still have a low curb or slight step depending on the bathroom layout and drainage design.
What are the benefits of a walk-in shower?
Walk-in showers are popular for their modern appearance, easier access, flexible design options, and efficient use of space. They can also improve comfort and long-term usability, especially in bathroom remodels where homeowners want a more open layout.
Do walk-in showers require special plumbing?
Walk-in showers often require careful plumbing and drainage planning. Depending on the design, the project may involve drain relocation, floor slope adjustment, waterproofing integration, shower valve placement, and fixture sizing to support proper performance and code compliance.
Are walk-in showers good for small bathrooms?
Yes. A walk-in shower can work very well in a small bathroom when the layout is planned correctly. Glass enclosures, streamlined fixture placement, and efficient drain positioning can help a smaller bathroom feel more open and functional.
Can you add a bench or niche to a walk-in shower?
Yes. Many walk-in showers include built-in benches, recessed wall niches, handheld shower fixtures, and other design features. These additions should be planned with the plumbing layout and waterproofing system so the finished shower remains durable and easy to use.
Is a walk-in shower a good choice for aging in place?
In many cases, yes. Walk-in showers are often chosen for aging-in-place bathroom upgrades because they can be designed with lower thresholds, easier entry, grab bars, seating, and handheld fixtures. The exact design depends on the space, plumbing layout, and accessibility goals.
Can a bathtub be replaced with a walk-in shower?
Yes. Many homeowners replace an existing tub with a walk-in shower as part of a bathroom remodeling project. The work may include drain changes, valve updates, waterproofing, wall modifications, and shower enclosure planning depending on the existing bathroom configuration.
