You’ve been stepping over that old bathtub for years. Maybe you’ve used it a handful of times in the last decade. Now you’re ready to reclaim that space with a shower that actually fits your life — one that’s beautiful, functional, and built to last.
But before you call a contractor, you have one pressing question: how long does a typical tub-to-shower conversion take?
The honest answer? It depends — but not in a frustrating, vague way. There are specific factors that compress or stretch a project timeline, and once you understand them, you can plan your renovation with clear expectations. For homeowners in Vancouver, WA, and the greater Portland metro, this guide breaks down exactly what drives the timeline, what to expect week by week, and how working with experienced local remodelers like Alta Casa makes the difference between a smooth project and a stressful one.
A tub-to-shower conversion replaces an existing bathtub with a dedicated shower space. At its most basic, that means removing the tub, adjusting plumbing, installing a shower pan or tile base, adding walls, and finishing with fixtures and glass enclosures.
But the scope can vary dramatically. A simple conversion using a prefabricated shower kit looks and feels very different from a custom tile walk-in shower with built-in niches, linear drains, and frameless glass. The difference in scope also means a significant difference in timeline, cost, and craftsmanship.
Benefits homeowners typically cite include better daily usability, improved accessibility (especially with walk-in or curbless designs), a more modern aesthetic, and — depending on your neighborhood and buyer pool — added resale appeal.
No two bathrooms are the same, and neither are their timelines. Here are the primary variables that affect how long your project will take:
A basic prefab swap can be done in as little as one to two days. A fully custom tile shower with floor-to-ceiling work, niche cut-ins, and a frameless glass enclosure could take one to three weeks.
If your new shower layout matches the existing drain and water supply locations, the plumbing work is minimal. But if you’re reconfiguring the layout — say, shifting from a tub filler and hand shower to a multi-head shower system — plumbing relocation adds time, cost, and often requires permits.
Tile installation in a shower environment requires proper setting, grouting, and curing. Rushing this step leads to cracked grout, failed waterproofing, and moisture damage behind the walls. Expect tile work alone to span two to four days, not counting drying time between stages.
This is the factor homeowners most often overlook. Custom tile, specialty fixtures, and specific glass panels may have lead times of several weeks. A well-run project starts material sourcing during the design phase — not after the demo has begun.
In Clark County (which covers most of Vancouver, WA), certain bathroom remodels require permits, particularly when structural changes or plumbing relocation are involved. Processing times vary, but building in extra time for permit approval — typically one to two weeks — is standard practice for professional remodelers.
Older homes in the Vancouver and Portland area sometimes reveal surprises once the tub comes out: outdated plumbing, inadequate waterproofing on old walls, and subfloor damage from years of moisture. These discoveries add time, but addressing them properly is non-negotiable.
Here’s a realistic breakdown of what a professional tub-to-shower conversion looks like from first call to final walkthrough:
This phase covers the initial site assessment, layout planning, material selection, and scope definition. A good contractor won’t rush this. Getting the design right up front prevents costly mid-project changes.
Tile, shower pans, glass enclosures, fixtures, and waterproofing membranes are ordered. Timeline depends entirely on what you’ve chosen. In-stock materials from local suppliers can arrive in days. Custom or special-order items may take three to four weeks.
If your project involves plumbing changes or structural modifications, permits are pulled before work begins. Your contractor handles this — reputable firms like Alta Casa include permit management as part of their full-service process.
The bathtub, surround, and any tile or drywall being replaced are removed. This is typically the fastest phase, but it’s also when surprises show up. Budget for the possibility of an extra day here.
New drain placement, supply line adjustments, and proper waterproofing installation (cement board, waterproofing membrane) happen here. This phase is critical — corners cut here cause expensive problems later.
Setting tile, grouting, and allowing adequate cure time before moisture exposure. Rushing this phase is the most common cause of shower failure within the first few years.
Shower heads, valves, niches, and glass enclosures are installed. Final plumbing connections are made and tested.
Final inspection (if permitted), cleanup, and a thorough walkthrough with the homeowner to confirm everything meets expectations.
Total Active Construction Time: 7–14 business days for a mid-to-high-end custom conversion. Total Calendar Time (including design, materials, and permitting): 4–8 weeks
Vancouver sits in Clark County, which has its own building department with specific permit requirements for bathroom remodels that include plumbing or structural work. Permits aren’t just bureaucracy — they protect your investment and ensure the work passes inspection, which matters when it’s time to sell.
The Pacific Northwest climate also factors into material choices. High humidity and significant rainfall mean proper waterproofing in shower enclosures is especially critical here. Vapor barriers, cement backer boards, and premium waterproofing membranes aren’t optional in this region — they’re standard practice for any quality build.
Local homeowners in neighborhoods like Felida, Salmon Creek, and Camas have also shown strong demand for clean, transitional, and spa-inspired shower designs — which tend to favor larger format tiles, frameless glass, and linear drains. These design choices affect both timeline and cost, and they require contractors with specific installation experience to execute well.
Even well-planned projects encounter bumps. The difference between a good contractor and a great one is how they handle surprises.
Challenge: Discovering rotted subfloor or moisture damage.
Solution: Professional remodelers inspect carefully during demo and address subfloor issues before any new installation begins. Skipping this creates a much larger problem six months later.
Challenge: Out-of-square or non-plumb walls.
Solution: Custom tile showers require level, plumb surfaces. A skilled tile setter knows how to address this during prep — it adds a day but prevents lippage and cracked grout down the road.
Challenge: Permit delays.
Solution: Submit permit applications early in the process, not after materials arrive. Alta Casa coordinates permitting as part of the project timeline to avoid last-minute holdups.
Challenge: Material back-orders.
Solution: Finalize selections during the design phase and order immediately. Identify backup options upfront so a supply delay doesn’t stall construction.
Challenge: Plumbing that doesn’t meet current code.
Solution: In older Vancouver and Portland-area homes, this comes up more than homeowners expect. Experienced remodelers identify code compliance issues during assessment and build the correction into the original scope.
A tub to shower conversion might look straightforward on a renovation video, but it combines tile work, waterproofing, plumbing, and finish carpentry — all of which need to work together correctly.
DIY conversions frequently fail not at installation, but at waterproofing. Water finds every gap, and by the time visible damage appears, the repair cost often exceeds what a professional installation would have cost upfront.
Working with a professional remodeler like Alta Casa means:
For a high-end conversion, professional execution is the only way to protect the investment you’re making in your home. Successful remodeling starts long before the first hammer swings. You can review industry standard remodeling contractor checklists to ensure you are hiring a dedicated professional.
Here’s exactly what the Alta Casa process looks like from first contact to project completion:
Step 1: Initial Consultation We walk through your existing bathroom, discuss your goals, and assess what the project actually involves — plumbing, structure, and all.
Step 2: Design and Material Selection You work with our team to select tile, fixtures, glass, and finishes. We guide you toward choices that fit both your aesthetic and your budget without making you feel pressured.
Step 3: Detailed Scope and Proposal You receive a clear, itemized proposal — no vague line items or mystery costs. The timeline is outlined here, including permitting if required.
Step 4: Permit Application (if applicable). We handle filing and follow-up with Clark County or the relevant local authority.
Step 5: Material Procurement Everything is ordered immediately upon contract signing to avoid delays.
Step 6: Pre-Construction Walkthrough Before the first day of demo, we walk through the space with you to confirm logistics — bathroom access, project staging, and daily communication expectations.
Step 7: Demolition of the old tub and surround was completed. Subfloor and wall conditions assessed.
Step 8: Plumbing and Waterproofing. New rough plumbing installed or adjusted. Waterproofing system installed and inspected before tile work begins.
Step 9: Tile Installation Setting, grouting, and curing — done correctly, with proper time between stages.
Step 10: Fixtures, Glass, and Final Finishes. Everything comes together. Plumbing connections tested and confirmed leak-free.
Step 11: Final Walkthrough and Punch List. You inspect the finished project with us. Any punch-list items are addressed before we consider the job complete.
In the Vancouver, WA, and Portland metro area, a mid-range tub to shower conversion typically runs between $5,000 and $12,000, depending on size, materials, and scope. A fully custom, high-end conversion with premium tile, frameless glass, and custom niches can run higher.

Budgeting advice: Build a 10–15% contingency into your budget. It’s not pessimism — it’s smart planning. Older homes especially benefit from this buffer, given the likelihood of discovering something unexpected behind the walls.
A tub-to-shower conversion is one of the most impactful upgrades you can make to a primary or guest bathroom. When planned properly and executed by experienced professionals, it transforms a space you tolerate into one you genuinely enjoy every day.
The typical timeline for a quality conversion — from design through construction — runs four to eight weeks when you factor in planning, permitting, and material lead times. Active construction typically takes one to two weeks for a mid-to-high-end project.
If you’re ready to stop working around a bathtub you never use and start planning the shower your bathroom deserves, Alta Casa is ready to help. Our team brings the local expertise, high-end craftsmanship, and project management that Vancouver and Portland homeowners trust.

Active construction on a mid-to-high-end custom conversion typically runs 7–14 business days. When you include the design phase, material procurement, and any permitting, the total calendar timeline is usually 4–8 weeks. A basic prefab conversion can be completed in 1–2 days, but that scope is quite limited in terms of design quality and longevity.
The biggest factors are scope (custom tile vs. prefab), plumbing relocation, material lead times, permit processing, and any unexpected conditions discovered during demolition — such as subfloor damage or outdated plumbing. Working with a contractor who plans for these variables upfront keeps your project on schedule.
Yes, in most cases. You’ll lose access to that specific bathroom during construction, so if it’s your only bathroom, you’ll want to plan accordingly or discuss scheduling with your contractor. Alta Casa typically structures work to minimize disruption to daily routines.
It depends on the scope. Cosmetic replacements that don’t involve plumbing changes typically don’t require permits. However, if you’re relocating the drain, modifying supply lines, or making structural changes, a permit from the Clark County Building Department is required. Alta Casa manages the permitting process as part of every qualifying project.

Mid-range conversions in this area generally run $5,000–$12,000. Custom, high-end projects with premium tile, frameless glass, and specialty features can exceed that range. Get a detailed, itemized proposal from any contractor you consider — vague estimates are a red flag.
In most cases, yes — though the feasibility depends on plumbing location, floor joist depth (for drain access), and structural layout. A proper site assessment by an experienced contractor will confirm what’s possible in your specific bathroom.
Inadequate waterproofing. Tile looks good on the surface, but if the substrate behind it isn’t properly protected, water infiltrates the wall and subfloor over time — causing mold, rot, and structural damage. By the time it’s visible, the repair often costs more than a professional installation would have.
