A walk-in shower can cost anywhere from a few thousand dollars to well over $20,000, and the single biggest factor is whether you install a prefabricated kit or build a fully custom tiled shower. In a marine climate like the Columbia River Gorge, a second factor matters almost as much: how much of the budget goes toward waterproofing and exhaust ventilation that actually keeps up with our wet season.
This guide pulls together cited 2025–2026 figures from This Old House, Fixr, and Bob Vila to show what a walk-in shower costs at each tier and which line items push the number up. We also state Camas Bath's own published range for the area. If you're still deciding between a walk-in shower and converting an existing tub, see our walk-in shower vs. tub-to-shower comparison instead of re-reading that trade-off here.
Key takeaways
- National 2025–2026 data puts a walk-in shower at roughly $4,000–$20,000, averaging $8,000–$12,000, depending on the source (This Old House, Fixr, Bob Vila).
- Prefab vs. custom tiled is the biggest cost lever: prefab kits commonly run $2,000–$8,000 installed, while full custom builds run $14,000–$20,000 or more.
- Waterproofing and exhaust ventilation carry more weight in Clark County's marine climate than in drier regions — budget for a fully sealed pan/membrane assembly and a properly sized, exterior-ducted fan.
- Washington sales tax applies to both labor and materials; Camas's combined rate is 8.8% as of Q3 2026 (WA Dept. of Revenue).
- Camas Bath's published range for a Walk-In / Custom Tile Shower is $12,000–$22,000, reflecting standard frameless glass, custom tile, and full waterproofing.
The short answer
This Old House (2026) puts walk-in shower installation nationally at $4,000–$20,000, with a typical homeowner spending around $12,000. Fixr's independent 2025 data lands in a similar band: a $5,000–$11,000 typical range, an $8,000 average, and a full spread of $3,000–$20,000. Bob Vila's 2024 shower-remodel breakdown narrows a walk-in specifically to $4,200–$8,500.
Build type — prefabricated versus custom tiled — is still the number one predictor of where your project lands. Washington sales tax then applies on top of the contractor's labor and material total; Camas's combined rate is 8.8% as of Q3 2026 (Washington Department of Revenue).
Cost by build type: prefab, midrange tiled, custom
The gap between a prefab kit and a full custom build is the largest lever in a walk-in shower budget. This Old House and Fixr both size it out, and their tiers line up closely.
| Build type | This Old House (2026) | Fixr (2025) |
|---|---|---|
| Prefabricated kit | $4,000–$7,000 installed | $2,000–$8,000 (~$300/sq ft avg) |
| Midrange tiled | $8,000–$13,000 | Not broken out separately |
| Full custom / high-end | $14,000–$20,000 or more | $5,000–$20,000 (~$600/sq ft avg) |

What drives the price: the line items
Once you know your build type, the finish choices inside it are what separate the low end of a range from the high end. This Old House (2026) and Fixr (2025) break several of these out individually, and two of them — the shower pan and the waterproofing membrane — matter more in a climate that sees roughly 40+ inches of rain a year than they would somewhere dry.
- Tile: ceramic/porcelain runs $12–$30 per square foot; natural stone runs $20–$50 per square foot (This Old House, 2026)
- Shower pan: a prefab pan runs $800–$1,500; a custom-built pan runs $1,200–$3,000 (This Old House, 2026)
- Waterproofing and backer board: $800–$1,500 (This Old House, 2026) — this line item is not optional in a marine climate; a shower pan and wall assembly that isn't fully sealed is where slow leaks and hidden mold start
- Glass: a framed door runs $500–$1,200; a frameless enclosure runs $1,000–$3,000 or more (This Old House, 2026)
- Labor: roughly $2,000 for a prefab install versus roughly $4,800 for a custom install (Fixr, 2025)
- Bob Vila (2024) notes labor alone commonly makes up about half of a shower project's total cost
Why exhaust ventilation belongs in the budget
A walk-in shower with more open square footage of wet wall — especially a curbless or frameless design — pushes more humidity into the room than a small enclosed stall. In the Pacific Northwest, where indoor humidity is already elevated for months at a time, an undersized or poorly ducted exhaust fan is one of the most common reasons a new shower develops mildew within a year or two. Sizing the fan to the room's cubic footage and ducting it to the exterior (not into an attic) is a code and moisture-control basics, not a luxury upgrade — budget for it alongside the shower pan and waterproofing rather than treating it as an afterthought.
Camas Bath's published range
Camas Bath's own published range for a Walk-In / Custom Tile Shower is $12,000–$22,000, which sits toward the tiled-to-custom end of the national data above — frameless glass, custom tile, and a fully sealed waterproofing assembly are included as standard rather than upgrades. That mirrors the same cost pressures we cover in our Camas bathroom remodel cost guide: Washington sales tax on labor and materials, plus regional Portland–Vancouver metro construction cost trends.
None of the national sources above price a Camas- or Clark County-specific project, so treat their figures as the planning band and our published range as the local anchor point. The most reliable number for your bathroom is still a fixed quote against your actual footprint, moisture exposure, and finish choices.
3-year workmanship warranty
Every walk-in shower we install is backed by a 3-year workmanship warranty, in addition to the manufacturer warranties on the tile, glass, and fixtures we install.
Frequently asked questions
- How much does a walk-in shower cost in Camas?
- Camas Bath's published range for a Walk-In / Custom Tile Shower is $12,000–$22,000, which includes frameless glass and custom tile as standard. For national context, This Old House (2026) puts walk-in showers at $4,000–$20,000 (average ~$12,000), and Fixr (2025) puts them at $5,000–$11,000 typical ($8,000 average). Add applicable Washington sales tax — 8.8% inside Camas as of Q3 2026 — on top of the contractor total.
- What is the difference in cost between a prefab and a custom walk-in shower?
- This Old House (2026) prices a prefab kit at $4,000–$7,000 installed versus $14,000–$20,000 or more for a full custom tiled build. Fixr (2025) shows a similar gap, at roughly $300 per square foot for prefab versus $600 per square foot for custom. The difference comes from tile, a custom-built shower pan, waterproofing, and labor hours.
- Why does waterproofing cost more to get right in the Pacific Northwest?
- It doesn't necessarily cost more in dollars — This Old House (2026) prices waterproofing and backer board nationally at $800–$1,500 regardless of region — but skipping or undersizing it is riskier in a climate with sustained indoor humidity. A shower pan and wall assembly that is fully sealed, paired with a properly sized exhaust fan ducted to the exterior, is what keeps a Clark County shower from developing hidden mold within the first year or two.
