Bathroom Remodeling
Most Los Angeles homeowners use their bathroom twice a day and think about remodeling it once a decade. The gap between those two facts is where a lot of quiet frustration lives: the tile that has overstayed its welcome, the shower that feels too tight, the vanity that makes the entire room feel smaller than it is.
Green Star Remodeling builds bathrooms that close that gap. Not trend-driven renovations that feel outdated in a few years, but spaces designed around how you actually start and end your day. Custom showers built to precise dimensions. Tile installed with expert attention to alignment and waterproofing. Finishes selected to perform under daily use while maintaining a clean, lasting appearance.
We’ve completed bathroom renovations and kitchen remodeling projects, and ADU design and construction across San Fernando Valley, Tarzana, Santa Clarita, Calabasas, and greater Los Angeles for over 20 years. Every project is permitted, managed, and personally overseen by our licensed team from consultation through final walkthrough.

Los Angeles Bathroom Renovation Services
Master Bathroom Renovations
We design master bathrooms around real daily use: layout, lighting, and flow before fixtures. Custom vanities, frameless showers, heated floors, and layered lighting are integrated into one cohesive system.
Walk-In Showers & Frameless Glass
Custom walk-in showers built with proper waterproofing, large-format tile, and precise drainage. Options include curbless entries, rainfall systems, linear drains, benches, and recessed niches.
Soaking Tubs & Freestanding Baths
Freestanding tubs in cast iron, acrylic, or stone resin selected based on structure, heat retention, and water capacity. Plumbing and placement are planned before installation for proper performance.
Custom Vanities & Storage
Custom vanities built to exact dimensions with floating or built-in designs, dual layouts, and optimized storage. Countertops include marble, quartz, quartzite, and concrete with premium hardware from Emtek, Atlas, and Waterstone.
Tile Work & Flooring
Expert tile installation using porcelain, marble, travertine, ceramic, zellige, mosaic, and cement tile. Layout, spacing, and substrate preparation are planned for durability and clean visual alignment.
Lighting & Fixture Upgrades
Layered lighting systems with recessed ambient lights, mirror task lighting, and accent fixtures. Designed for balanced brightness in the morning and comfort in the evening.
Small Bathroom Remodels
Efficient remodels for guest and secondary bathrooms focused on better layout, durability, and improved space use, built to the same quality standards as master baths.
Accessible & ADA-Compliant
Functional, modern ADA-compliant bathrooms with curbless showers, reinforced grab bars, accessible layouts, and wider clearances, designed for safety without an institutional look.
Critical Systems That Determine Bathroom Longevity
A bathroom is one of the most moisture-exposed areas in your home. Daily showers, humidity, cleaning, and water usage can lead to mold, damaged grout, failing tile, and structural problems if the space is not built correctly. When planning bathroom remodeling in Los Angeles, we focus on the critical systems that make a bathroom durable, code-compliant, and built to perform for years. Unlike other remodeling projects, bathroom success depends heavily on waterproofing, the hidden system that protects everything behind the walls.
Layout & Accessibility
Bathroom layout affects plumbing placement, ventilation, waterproofing requirements, and everyday comfort. Many Los Angeles homeowners want larger showers, double vanities, walk-in showers, or accessibility upgrades that require careful planning. Structural and layout improvements include:
- ✓ Fixture relocation for toilets, sinks, showers, and tubs
- ✓ Walk-in shower conversions with proper slope and waterproofing
- ✓ Wall removal or relocation for improved space
- ✓ Framing modifications for shower and tub enclosures
- ✓ Structural reinforcement for heavy fixtures
- ✓ Accessibility upgrades including grab bars, curbless showers, and ADA-compliant fixtures
- ✓ Compliance with Los Angeles Building Code requirements
Older Los Angeles homes often have inefficient bathroom layouts. A remodel allows homeowners to improve functionality while coordinating structural changes with plumbing, ventilation, and waterproofing needs.
Plumbing Systems
Most bathroom remodels require plumbing updates, especially when fixtures are moved. Poor plumbing design can lead to slow drains, low water pressure, leaks, and future repairs. Plumbing improvements include:
- ✓ PEX or copper repiping to replace outdated galvanized steel, cast iron, or polybutylene pipes
- ✓ Toilet flange relocation and proper installation
- ✓ Sink and vanity supply line updates
- ✓ Drain line sizing and slope improvements
- ✓ Water line relocation for new fixtures
- ✓ Pressure-balanced or thermostatic shower valves
- ✓ Low-flow fixtures meeting California water conservation standards
- ✓ P-trap installation and drainage improvements
Pre-1994 Los Angeles homes often contain aging plumbing systems that restrict performance. Updating these systems during remodeling improves reliability and prevents future water issues.
Waterproofing
Waterproofing is the foundation of a successful bathroom renovation. Water can travel behind tile, through cracks, and into wall cavities, causing mold, rot, and structural damage. Professional waterproofing includes:
- ✓ Substrate preparation before installation
- ✓ Waterproof membrane application
- ✓ Shower pan construction with proper drainage slope
- ✓ Waterproofing around shower walls, tubs, and pipe penetrations
- ✓ Moisture and vapor barrier installation
- ✓ Proper flashing around fixtures and penetrations
- ✓ 24-hour flood testing before tile installation
- ✓ Sealant application at grout joints and transitions
A bathroom can look beautiful on the surface while hidden water damage develops underneath. Proper waterproofing protects your investment and prevents costly repairs after completion.
Ventilation & Moisture
Bathrooms create constant humidity from showers and baths. Without proper ventilation, moisture can lead to mold growth, peeling paint, and structural deterioration. Ventilation improvements include:
- ✓ Proper exhaust fan sizing
- ✓ High-capacity ventilation for larger bathrooms
- ✓ Exterior ductwork installation
- ✓ Backdraft dampers
- ✓ Humidity-sensing and timer-controlled fans
- ✓ Smart ventilation systems
- ✓ Compliance with California Title 24 ventilation standards
Many older Los Angeles bathrooms have outdated fans or ventilation that releases moisture into attics or crawlspaces. Proper routing and sizing protect indoor air quality and prevent moisture problems.
Electrical & Lighting
Bathrooms require careful electrical planning because of water exposure and safety requirements. Electrical upgrades include:
- ✓ GFCI protection for bathroom outlets
- ✓ Dedicated circuits for fans, heated floors, and towel warmers
- ✓ LED lighting upgrades
- ✓ Vanity lighting designed for better visibility
- ✓ Recessed lighting with proper wet-area clearances
- ✓ Dimmer switches and smart lighting controls
- ✓ Bathroom-rated electrical fixtures
A well-designed lighting system improves both safety and daily functionality while creating a more comfortable bathroom environment.
Fixtures & Finishes
Once structural, plumbing, waterproofing, and electrical systems are complete, finishes define the look and durability of your bathroom. Finish selections include:
- ✓ Porcelain and natural stone tile
- ✓ Moisture-resistant grout options
- ✓ Custom shower layouts and tile patterns
- ✓ Moisture-resistant vanity cabinetry
- ✓ Quartz, granite, and marble countertops
- ✓ Durable faucet and fixture finishes
- ✓ Frameless and framed shower enclosures
- ✓ Low-flow and smart toilet options
- ✓ Bathroom-specific paint and caulking
- ✓ Hardware and accessories
The best bathroom finishes combine style with durability, resisting moisture while maintaining their appearance through daily use.

Hidden Challenges
Bathroom Remodeling in Older Los Angeles Homes
Older Los Angeles bathrooms often contain hidden issues such as outdated plumbing, poor waterproofing, damaged framing, mold growth, and inefficient layouts.
Demolition can reveal corroded galvanized supply lines, aging cast iron drain pipes, water-damaged subfloors, hidden moisture damage, outdated electrical systems, and structural challenges that affect layout changes.
We evaluate existing conditions, explain required improvements, and create a renovation plan based on what your bathroom actually needs. Pre-1994 homes may require additional updates to plumbing, electrical systems, or ventilation. Local conditions also matter: hillside properties may have foundation concerns, while coastal areas may experience faster fixture corrosion.
Materials & Finishes We Work With
Tile & Stone
Porcelain is the most reliable choice for floors and showers due to durability, moisture resistance, and large-format options. Natural marble offers depth and variation but requires sealing and maintenance. Zellige adds texture, while glass mosaic works best for accents and niches.
Cabinetry & Vanities
Custom and semi-custom cabinetry built in wood and MDF with high-performance hardware from Blum. Finish options include paint, lacquer, oak, walnut, and white oak for a clean, durable bathroom aesthetic.
Plumbing Fixtures
We specify trusted brands including Kohler, Brizo, Grohe, Hansgrohe, Rohl, Waterstone, and California Faucets. Finishes are coordinated across the entire bathroom: chrome, brushed nickel, matte black, brass, and bronze.
Shower & Tub Systems
Thermostatic shower systems maintain consistent temperature and prevent pressure fluctuations during use. Freestanding tubs are selected based on water heater capacity, fill time, and comfort performance, not just appearance.
