Bathroom Remodel Overview
Why Choose Buildda?
Buildda bathroom remodel approach:
- Waterproofing membrane over the substrate, not under it - Showers fail at the corners and the curb. We install a waterproofing membrane (Schluter-Kerdi or equivalent) over the cement board before tile, so the moisture barrier sits where the water actually is, not buried behind drywall where leaks go undetected for years.
- Plumbing decision locked at design - Moving the toilet, shower drain, or vanity supply lines costs thousands and adds weeks; keeping them where they are is the most efficient remodel. We ask the keep-vs-move question at the estimate stage so you're not deciding it mid-demolition with a slab open.
- California water-efficiency code, in writing - Toilets at 1.28 GPF, showerheads at 1.8 GPM, faucets at 1.2 GPM (CA Title 20). Permit-required scope goes through DBS inspection; we pull the permit under license #1131088 and the workmanship is covered for 2 years.

Buildda Tip
The most expensive part of a bathroom remodel is usually what you cannot see - waterproofing, plumbing, and subfloor prep. Cutting corners on these hidden layers is how bathrooms end up with leaks and mold two years later. We always install a full waterproof membrane behind shower tile and test drain connections before closing up walls. It adds a day to the schedule but saves you from a much bigger problem down the road.
What to Know Before You Start
Bathroom remodels can throw surprises - rotted subfloor, plumbing that doesn't meet current code, wiring without GFCI, tile substrate done wrong, mold behind walls. We can't always tell what's hiding until we open it up. How we handle that varies by project: sometimes we'll open a small section before pricing, sometimes we'll use moisture meters or a camera, sometimes the contract has a contingency built in. We talk through the right approach during your consultation, before anything is signed.
As your general contractor (CA #1131088, B/General), Buildda coordinates the project; the plumber on your job does plumbing every single day, the electrician does electrical, the tile setter does tile. Real expertise comes from doing one trade every day, not switching between many. Permits and city fees are paid by the homeowner directly to the city; we file the application and hand over the receipt.

Bathroom remodels consistently rank among the top renovations for resale return. Buyers notice updated bathrooms immediately.

Accessibility
Curbless showers, grab bars, comfort-height toilets, and wider doorways let you age in place safely. Smart to plan for now even if you do not need them yet.
Moisture & Mold Prevention
Proper waterproofing membranes, upgraded exhaust fans, and correct tile installation prevent the mold and water damage that plague older LA bathrooms.
Licensed Work, Proper Permits
Plumbing and electrical changes require permits in Los Angeles. Our licensed team (CA #1131088) pulls the right permits and schedules inspections so the work is done to code.

Transparent Pricing
Clear Pricing. Exceptional Results.
Bathroom remodels in LA range from $15,000 for a half-bath refresh to $95,000+ for a full master suite. Mid-range guest baths typically run $25,000-$45,000. Cost variables: keeping vs. moving plumbing, fixture grade, tile selection, and whether the existing subfloor needs structural work. Permits add 4-8 weeks before demolition starts on permit-required scope.
The biggest single cost decision is whether the toilet, shower drain, or vanity supply lines move. Keeping them where they are is the most efficient remodel. Moving any of them costs thousands more in labor and weeks more in schedule because subfloor opens up and inspections cycle. Other variables: fixture grade (a $200 toilet vs. a $1,500 wall-hung carrier toilet), tile selection (porcelain field tile vs. natural stone vs. handmade zellige), waterproofing approach (we install Schluter-Kerdi membrane over cement board on every shower so the moisture barrier sits where the water actually is), and whether the existing subfloor has hidden moisture damage from a slow leak. We do California Title 20 fixture flow rates verified at install: 1.28 GPF toilets, 1.8 GPM showerheads, 1.2 GPM faucets. License #1131088, 2-year workmanship warranty in writing.

Frequently Asked Questions
Common questions about bathroom renovation projects with Buildda
Ask us directly
Have a question about your project? Text it to us with a photo or a short description.
Do bathroom remodels require permits?
It depends on your city and the work. Plumbing, electrical and structural changes are what cities look at; whether cosmetic-only updates (paint, fixtures, hardware swaps) need one also depends on the city. A valid permit ensures the project meets local code, factors into homeowners insurance, and prevents complications when selling the home. We handle permit applications and schedule the required inspections.
How can I save money on a bathroom remodel?
Several practical paths reduce costs. Stick to the existing layout so plumbing and electrical do not need to be moved (relocating these is the biggest hidden expense in a bathroom remodel). Shop sales for fixtures and tile. Mix premium-tier items in the visible spots (faucet, vanity, mirror) with budget-friendly choices in less-visible places (shower hardware, exhaust fan). Refinish rather than replace what works.
How long does a bathroom remodel take?
A basic cosmetic refresh might take 3-4 weeks. A larger renovation involving plumbing changes, structural work, or custom-fabricated elements typically runs 4-7 weeks or more. Delays often come from custom-order lead times (especially custom vanities or imported tile), inspection scheduling with the city, or unexpected structural issues uncovered during demolition. Build buffer time into the schedule from the start.
How can I improve water efficiency?
Choose WaterSense-labeled faucets, showerheads, and toilets. WaterSense fixtures use significantly less water without compromising performance because of internal pressure-compensating designs. Upgrading to low-flow systems can meaningfully reduce monthly utility bills, especially in California where water rates have climbed steadily. The fixtures pay back over time through reduced water bills, especially in higher-use households with multiple bathrooms.
Is a tub or walk-in shower better?
It depends on your lifestyle. A walk-in shower can save space and offer easier access, while a bathtub is often important for families with young children or for those who love soaking. Consider resale preferences in your area - some buyers like having at least one tub.
How do I maximize storage in a small bathroom?
Use recessed niches inside the shower wall for shampoo and soap storage. Choose wall-mounted or floating vanities to open up floor space visually and physically. Build vertical shelving or tall linen cabinets to maximize cubic feet without expanding the footprint. Mirror cabinets above the sink double as storage. The cumulative effect adds up to noticeably more usable space in a small room.
What's the best way to light a bathroom?
Layer the lighting in three tiers: ambient (overhead recessed lights or a ceiling fixture for general brightness), task (vanity sconces or backlit mirrors for shaving and makeup), and accent (LED strip lighting under vanities or dimmable cove lights for evening). The combination prevents shadows on the face, makes the space feel larger, and lets the room shift between functional and relaxing moods.
How do I make a bathroom senior-friendly or accessible?
Install a curbless walk-in shower so there is no step to navigate. Add grab bars near the shower entry, inside the shower itself, and near the toilet. Use comfort-height (taller) toilets, which are easier to sit on and stand from for older users. Choose slip-resistant flooring (matte porcelain or textured tile) rather than glossy surfaces that become slippery when wet underfoot.
