Converting a shower to a bathtub is one of those smart, lifestyle-friendly updates that can make your home feel more relaxing while widening its appeal to future buyers. For families, a tub simplifies bath time. For anyone with a busy schedule, it provides a space to unwind, recover, and reset. It also fits beautifully into a whole-home plan when you have the right team guiding layout, plumbing, and permitting. As Northern California locals, Intelligent Choice Builders handles each step with care and code knowledge, backed by our full suite of complete home renovation services.
Why consider a tub now?
Recent buyer data shows that 78% of home shoppers rate having both a shower and a tub in the primary bath as essential or desirable, which means keeping at least one bathtub can boost day-one livability and resale appeal. Design trends point the same way: soaking tubs are the most popular choice among renovating homeowners, at 62%, with durable, easy-care acrylic leading as the top material upgrade.
These insights shape our recommendations on size, placement, and materials so your conversion looks great and performs well for years.

Understanding the Benefits of Converting a Shower to a Bathtub
A well-planned shower-to-tub conversion can make daily life easier and your home more welcoming. Families appreciate an easier bath routine for kids. Fitness-minded homeowners use a deep soak to recover. Guests get a more versatile setup, and future buyers see broader appeal. When you keep at least one bathtub in the home, you preserve flexibility for different life stages and lifestyles. With Intelligent Choice Builders guiding layout, plumbing, and permitting, you get a tub that looks custom and works flawlessly.
Pro tip: If you’re short on space, consider an alcove soaking tub with a clean apron front. You’ll gain actual soaking depth without increasing your footprint.
Key Design Considerations for Your Shower-to-Bathtub Conversion
- Space planning: Verify overall length (60″ is common), width (30–32″ minimum for comfort), and clearances for cleaning and access.
- Style compatibility: Choose profiles and finishes that match your existing vanity, tile, and fixtures so the new tub looks built-in, not “added on.”
- Accessibility: Add a low step-over, anti-slip floor, and a handheld shower on a slide bar. Consider a deck-mounted filler with a thermostatic valve for safer temperatures.
- Waterproofing: Upgrade to modern sheet membranes behind tile and a properly sloped tub lip to prevent long-term moisture issues.
- Lighting & ventilation: Plan task lighting over the bath and confirm your fan meets current CFM and noise ratings for a quieter space.
Pro tip: Ask us to confirm your floor loading and drain location before you fall in love with a specific tub. A one-hour site check can save days.
Choosing the Right Bathtub: Types and Styles Explored
- Alcove tubs: Space-efficient, great for conversions, and easy to pair with a three-wall surround.
- Freestanding tubs: A sculptural upgrade if you have the square footage and a centered drain, often best for primary baths.
- Drop-in or undermount: Ideal for creating a custom deck with stone or quartz, giving you a spa-like feel.
Materials to consider:
- Acrylic: Lightweight, warm to the touch, and budget-friendly.
- Cast iron: Classic, exceptionally durable, and quiet, but heavier and may require floor reinforcement.
- Composite/stone resin: Offers a modern look with a solid feel and good heat retention.
Size & features:
- Right-size depth (15–18″ to overflow for soaking), ergonomic backrests, armrests, and optional air or whirlpool systems. If you want jets, plan a dedicated circuit and an access panel.
Pro tip: Bring us your “inspiration” photos. We’ll translate the look into tubs and trims that are actually available and code-compliant in Northern California.
The Remodeling Process: What to Expect
- Assessment & planning: Field-measure the alcove, verify drain and venting, check subfloor, and confirm structural needs.
- Design selections: Choose a tub, valve set, surround, tile, and trim metals that match the rest of your bath.
- Permits: We handle permit scope, drawings if required, and schedule inspections.
- Demo & prep: Remove the shower base and walls, repair framing as needed, and install waterproofing.
- Plumbing & electrical: Set the tub, relocate or upgrade the valve, add the handheld, and run power if you have jets.
- Finish work: Tile or solid-surface surround, caulking, fixtures, lighting, paint, and cleanup.
- Final walkthrough: We test every component and review care instructions with you.
Timeline: A straightforward conversion typically runs 3–7 working days once materials are onsite; allow lead time for specialty tubs or stone.
Cost Insights: Budgeting for Your Shower-to-Bathtub Remodel
Your final number depends on several factors, including tub type, surround choice (tile vs. solid surface), plumbing moves, and Bay Area labor.
- National reference points:
- Typical bathtub installation totals around $2,100 on average with material and labor, depending on tub type and scope.
- Broader national ranges for replacement/install commonly fall between ~$1,500 and $8,000.
- A basic install line-item is often $1,380–$2,438 before upgrades or repairs.
- Bay Area context:
Bathroom remodeling carries a regional premium; reputable sources place many Bay Area bathroom projects in the $20,000–$60,000+ range when multiple finishes and trades are involved.
What this means for a shower-to-tub conversion:
- Streamlined swap (alcove acrylic tub, keep plumbing location, solid-surface panels): Often budgets in the low-to-mid thousands, aligning with national install averages plus demolition and surround.
- Mid-range (new valve, tile surround, minor plumbing moves): Expect several thousand more for tile, waterproofing, and labor typical of the Bay Area market.
Inference note: Large retailers quote wet-area conversions such as tub-to-shower in the $6,000–$10,000 band; a shower-to-tub project with similar tile and plumbing complexity can land in a comparable range depending on finishes and scope.
Pro tip: Ask us for two prices: a value-engineered package with a durable acrylic alcove tub and panels, and a premium package with tile and upgraded fixtures. Seeing both lineups side-by-side clarifies where upgrades pay off.
Avoiding Common Mistakes During the Conversion
- Skipping waterproofing details: Proper membranes, corners, and penetrations prevent future leaks.
- Forgetting lighting and ventilation: New sightlines may require a task light and a right-sized, quiet fan.
- Under-sizing the tub: Confirm soaking depth and back support before ordering.
- Not planning access: If you choose jets, you’ll need a discreet service panel and dedicated power.
- Choosing the wrong surround for your lifestyle: Tile is beautiful but needs grout maintenance; panels simplify care.
Industry pros consistently call out planning, pipe condition, and reputable installers as success factors for wet-area conversions.
Pro tip: Before demo, we pressure-test and camera-inspect suspect lines in older homes. It’s a small upfront cost that can prevent change orders.
