Tarzana Bathroom Transformation: A Complete Before & After Remodel Case Study

Nothing demonstrates the transformation power of professional bathroom remodeling like real-world results. This case study follows a complete bathroom renovation in a 1968 Tarzana home—from outdated original fixtures to a stunning modern retreat. See how strategic planning, quality materials, and expert execution turned a problematic bathroom into a beautiful, functional space worth every dollar invested.

This project represents typical challenges Valley homeowners face when remodeling vintage properties. From hidden plumbing issues to space constraints, the transformation showcases how professional contractors overcome obstacles to deliver exceptional results on budget and schedule.

The Challenge: A 1960s Bathroom Frozen in Time

The homeowners, a young family in the heart of Tarzana near Tarzana Neighborhood Council area, purchased their charming 1968 ranch home for its location and potential. However, the hall bathroom remained completely original—and not in a good way. Fifty-five years of use without updates created a space that was dated, dysfunctional, and showing serious signs of failure.

The original bathroom featured:

• Pink tile throughout: Wall-to-wall original ceramic in a color that limited design options and immediately dated the space
• Deteriorating fixtures: Original toilet, pedestal sink, and bathtub showed decades of wear with permanent staining and damage
• Inadequate lighting: Single overhead fixture with yellowed plastic cover provided poor illumination for grooming tasks
• Zero storage: Pedestal sink offered no cabinet space; medicine cabinet was tiny and rusted
• Failing grout and caulk: Cracked, missing grout allowed water intrusion; original caulk was black with mold
• Poor ventilation: Undersized exhaust fan that barely functioned created persistent moisture and mildew problems
• Water damage signs: Soft flooring near tub, water stains on ceiling below, musty odor indicating hidden moisture issues

Beyond aesthetics, the bathroom presented safety concerns. The tub’s slippery surface with no grab bars posed fall risks. Electrical outlets lacked GFCI protection required by current codes. The inadequate ventilation promoted mold growth affecting the family’s health. This wasn’t just an ugly bathroom—it was a problematic one requiring immediate attention.

Initial Assessment and Hidden Problems

Jade Construction & Remodeling’s initial assessment revealed problems beyond what was visible. Using moisture meters and infrared cameras, we identified water damage behind the tub surround and beneath flooring—issues the homeowners didn’t know existed but which would have caused catastrophic failure within 1-2 years.

Our comprehensive evaluation found:

• Subfloor rot: Water intrusion through failed grout damaged 40% of bathroom subfloor requiring replacement
• Original plumbing issues: Galvanized supply lines severely corroded and restricting water flow; drain lines showing signs of deterioration
• No waterproofing: 1960s installation used only cement board with no waterproof membrane—standard at the time but inadequate by today’s requirements
• Electrical deficiencies: Non-GFCI outlets near water, inadequate lighting circuits, and outdated wiring methods
• Ventilation failure: Original fan moved barely 30 CFM versus 50+ CFM required by current California building codes
• Structural concerns: Wall framing showed moisture damage requiring partial replacement

These discoveries aligned with typical issues in vintage Tarzana homes. Rather than viewing them as problems, we presented them as opportunities—the chance to update all systems comprehensively while the walls were open, ensuring decades of trouble-free operation.

Design Goals and Budget Planning

The homeowners had a clear vision: transform their dated, dysfunctional bathroom into a modern, spa-like retreat without breaking the bank. They allocated $25,000 for the project based on typical Tarzana bathroom remodel costs, with a $5,000 contingency for unexpected issues—which proved prescient given the hidden damage discovered.

Design priorities included:

• Maximize storage: Replace pedestal sink with vanity providing substantial cabinet space
• Improve functionality: Better lighting, proper ventilation, and modern fixtures
• Create spa atmosphere: Calm, neutral palette with natural materials and quality finishes
• Enhance safety: Non-slip flooring, grab bars, proper lighting, GFCI outlets
• Long-term durability: Quality materials and installation methods ensuring decades of service
• Energy efficiency: Water-saving fixtures and LED lighting to reduce utility costs

We developed designs balancing aesthetics with practicality. Large-format tile would minimize grout lines, reducing maintenance while creating a clean, contemporary look. A floating vanity would maximize the feeling of space in the small bathroom. Walk-in shower with frameless glass would feel more luxurious than the old tub without requiring layout changes that increase costs.

Material selections prioritized value—choosing mid-range products with high-end appearance. Porcelain tile mimicking marble delivered luxury looks at 60% of natural stone costs. Quality fixtures from established brands provided reliability without premium pricing. This strategic approach delivered maximum impact within budget, avoiding the common mistakes that derail bathroom projects.

For homeowners considering similar transformations, kitchen remodeling or outdoor patio upgrades often follow successful bathroom projects, applying the same quality approach throughout the home.

Phase 1: Demolition and Discovery

Demolition began with careful removal of fixtures and finishes. We salvage what’s possible for donation, but in this case, the bathroom’s condition meant everything went to disposal. Within hours, the true extent of problems became visible—confirming our initial assessment and revealing a few additional surprises.

Demolition revealed:

• Extensive subfloor damage requiring 60% replacement (more than initially estimated)
• Shower drain improperly installed and leaking for years
• Wall framing with termite damage requiring treatment and partial replacement
• Original vent stack showing signs of corrosion at connections
• Electrical junction boxes installed incorrectly and creating potential fire hazards

Unexpected Issues and Solutions

The termite damage was the project’s biggest surprise—not visible during initial inspection but apparent once walls opened. We immediately called a licensed pest control company for treatment, then replaced affected framing with properly treated lumber. This added $1,200 to the project but was absolutely necessary for structural integrity.

The improperly installed drain required rerouting—adding complexity but ensuring proper function. We upgraded to modern ABS drain lines with proper slope and secure connections. While this added another $800, it prevented future drain problems that could have required demolishing the new bathroom to fix.

These discoveries validated the homeowners’ decision to work with licensed, experienced contractors. According to National Kitchen and Bath Association industry research, professional contractors discover hidden issues in 70% of vintage bathroom remodels—exactly why contingency budgets are essential. Our experience allowed us to address problems efficiently without derailing the schedule.

Phase 2: Infrastructure Upgrades

With demolition complete and hidden issues addressed, we focused on updating all systems to current standards—the foundation of a bathroom that performs flawlessly for decades. This phase represents the most critical investment, even though much of it becomes hidden behind finished surfaces.

Infrastructure improvements included:

Plumbing Upgrades:

• Replaced all galvanized supply lines with PEX—flexible, durable, and resistant to Valley hard water
• Installed new shut-off valves for easy maintenance
• Upgraded drain system with proper venting and slope
• Installed new shower valve with pressure-balancing and temperature control
• Added water hammer arrestors to prevent pipe noise

Electrical Improvements:

• Installed GFCI outlets per code requirements
• Added dedicated lighting circuit with dimmer capability
• Upgraded fan circuit to handle more powerful ventilation system
• Installed proper junction boxes for all connections
• Added heated towel bar circuit for luxury touch

Structural and Waterproofing:

• Replaced damaged subfloor with properly rated plywood
• Installed waterproof membrane on all shower surfaces
• Applied liquid waterproofing to vulnerable areas
• Used cement board backing for all tile areas
• Ensured proper shower pan slope for complete drainage

Ventilation System:

• Installed 110 CFM Panasonic WhisperCeiling fan (ultra-quiet, highly efficient)
• Added humidity sensor for automatic operation
• Properly vented to exterior (not attic) per code
• Installed insulated ductwork to prevent condensation

These upgrades transformed the bathroom’s invisible infrastructure from problematic to exemplary. Modern plumbing ensured reliable water delivery and drainage. Updated electrical provided safety and flexibility for current and future needs. Proper waterproofing protected the home’s structure. Effective ventilation prevented the mold and moisture issues that plagued the original bathroom.

Phase 3: Installation and Finishing

With infrastructure complete and inspections passed, installation began—the phase where design vision becomes reality. Quality installation separates good remodels from great ones, and our experienced craftsmen ensured every detail met our exacting standards.

Tile Installation:

We installed 12×24 porcelain tile in a soft gray tone throughout, creating visual continuity that makes the small bathroom feel larger. Large format tile also meant fewer grout lines—reducing maintenance and creating cleaner lines. In the shower, we created a feature wall using the same tile in a vertical stack pattern, adding visual interest without additional cost.

Tile work took three days—one for floor, two for walls and shower. Our installers used premium thin-set and grout products designed for wet areas. Every cut was precise, every corner perfect. The result was flawless tile work that looks professionally installed because it is—a stark contrast to DIY attempts or cheap contractor work.

Fixture Installation:

Selected fixtures delivered modern functionality with timeless style:

• Floating vanity (36″): White shaker style with soft-close drawers, quartz countertop, undermount sink
• Toilet: Kohler Cimarron comfort-height, WaterSense certified (1.28 GPF)
• Shower system: Delta monitor valve with handheld and fixed showerhead combination
• Frameless glass enclosure: 3/8″ clear glass, hinged door for easy access
• Lighting: LED vanity lights, recessed shower light, modern overhead fixture
• Hardware: Matte black faucet, towel bars, toilet paper holder, and robe hooks
• Mirror: Large frameless mirror maximizing light reflection

Final Details:

Final touches transformed the bathroom from construction site to finished retreat. Fresh paint in soft white brightened the space. We installed a recessed medicine cabinet providing storage without protruding into the room. Added grab bars in shower—stylish ones that enhance safety without looking institutional. Applied multiple coats of grout sealer to protect against Valley hard water staining.

Throughout installation, we maintained the clean, organized job site. Daily cleanup prevented dust migration to other areas. Protective coverings preserved the home. Professional conduct made the remodeling experience as pleasant as possible—important when contractors are in your home for weeks.

The Stunning Results: Before & After

The transformation exceeded the homeowners’ expectations. What was once a dated, dysfunctional bathroom became a modern retreat that feels spacious despite its compact 40-square-foot footprint. Every element works harmoniously—from the large-format tile creating visual flow to the frameless shower enclosure enhancing openness.

Visual Transformation:

• Pink tile replaced with contemporary gray porcelain creating calm, spa-like atmosphere
• Cramped pedestal sink area now features functional vanity with ample storage
• Dark, poorly lit space transformed into bright, welcoming room with layered lighting
• Old tub replaced with luxurious walk-in shower feeling far more spacious
• Dated fixtures upgraded to modern, water-efficient options in cohesive finishes

Functional Improvements:

• Storage increased from zero to substantial vanity cabinet space plus medicine cabinet
• Ventilation improved 250%—from inadequate 30 CFM to powerful 110 CFM humidity-sensing system
• Water efficiency enhanced with WaterSense fixtures saving 6,000+ gallons annually
• Safety dramatically improved with GFCI protection, grab bars, non-slip flooring, better lighting
• Maintenance reduced through sealed surfaces, quality materials, and modern systems

Long-term Value:

Beyond immediate improvements, this renovation delivers lasting value. Updated plumbing and electrical systems prevent expensive failures. Proper waterproofing protects the home’s structure. Quality materials and installation ensure the bathroom looks and functions beautifully for 20+ years. The investment of $28,500 added approximately $35,000-40,000 to home value—a solid return alongside the daily enjoyment of a beautiful, functional bathroom.

Key Takeaways from This Transformation

This project demonstrates several critical principles for successful bathroom remodeling in vintage Valley homes:

The homeowners’ decision to work with experienced professionals paid dividends throughout. Our ability to identify hidden problems early, solve issues efficiently, and maintain schedule despite discoveries saved them thousands compared to cheaper contractors who would have struggled with the complexity. The old adage proves true: you get what you pay for in remodeling.

What Homeowners Can Learn from This Project

If you’re considering a bathroom remodel in your vintage Tarzana home, this project offers valuable insights:

Budget Realistically: This $28,500 project included $3,500 in unexpected repairs. Without contingency budget, homeowners would have faced difficult choices or accrued debt. Always budget 15-20% above estimates for vintage homes—you’ll likely use it.

Address Everything: Cosmetic remodels in problematic bathrooms waste money. This family could have spent $15,000 on new tile and fixtures while ignoring plumbing, electrical, and waterproofing—only to face failures within years requiring complete re-dos. Comprehensive renovation, while more expensive initially, costs far less than multiple partial attempts.

Trust the Process: Discovering extensive damage during demolition can be alarming. However, professional contractors handle these situations routinely. Trust their recommendations, understand that hidden issues are normal in vintage homes, and focus on the end result—a bathroom that’s truly updated and reliable.

Invest in Quality: This bathroom used mid-range materials installed expertly. The result looks high-end because quality installation elevates even moderate materials. Conversely, luxury materials installed poorly look terrible and fail prematurely. Prioritize skilled labor and proper methods over premium materials every time.

Maintain Perspective: Living through bathroom renovation isn’t fun. Four weeks of construction dust, noise, and inconvenience tested the family’s patience. But keeping eyes on the prize—a beautiful, functional bathroom they’ll enjoy for decades—made temporary disruption worthwhile. The transformation’s magnitude justifies short-term sacrifice.
