What Is Included in Our Bathroom Remodeling Services
As your dedicated bathroom remodel contractor in Los Angeles, Aluna Construction takes full accountability for your renovation from initial framing to final plumbing trim. We do not cut corners behind walls where moisture resistance matters most.
How Our Bathroom Renovation Process Works
Bathroom construction requires tight coordination between plumbing, electrical, tile setting, and glazing trades. We execute your bathroom renovation through four disciplined stages:
1Consultation & In-Home Plumbing Audit
Winston Vlessing evaluates existing drain locations, venting stacks, water pressure, and electrical circuit capacity. We discuss your layout goals (such as converting a tub/shower combo to a walk-in shower) and establish clear scope boundaries.
2Scope of Work & Fixed-Price Agreement
You receive a transparent proposal detailing labor, rough materials, waterproofing specifications, and fixture allowances. There are no vague surprises or hidden subcontractor costs.
3Waterproofing, Rough MEPs & City Inspections
Daniel Vlessing directs on-site operations. We install pressure-balanced thermostatic valves, slope shower pans, install dual-layer waterproofing membranes, and undergo formal 24-hour city water tests before setting any tile.
4Tile Setting, Trim & Glass Installation
Master tile setters lay wall and floor finishes with laser-straight alignments. Vanities, stone tops, mirrors, and 3/8-inch ultra-clear frameless shower glass are installed and thoroughly tested.
Permits and LADBS / City Requirements
In Los Angeles, modifying shower pan waterproofing, replacing drain traps, moving water supply lines, or installing new 20-amp dedicated GFCI circuits requires a plumbing and electrical permit from the Los Angeles Department of Building and Safety (LADBS).
A critical inspection checkpoint in Los Angeles is the shower pan flood test: the shower drain is plugged, and the pan is filled with water for 24 hours to prove zero leakage before wall board or tile may be applied. Aluna Construction schedules and attends all city inspections, guaranteeing certified code compliance for your home.
Condo and HOA Considerations for Bathroom Remodels
Condominium bathroom renovations along the Wilshire Corridor, in Westwood, or in Century City—including our work at Century Hill, Century City—require specialized multi-family protocols.
Moving a toilet or shower drain in a concrete high-rise often requires coordination with neighbors below or non-destructive slab x-ray scanning to avoid cutting post-tension cables. Furthermore, main water riser shutoffs require 72-hour building notices, and tile floors must be paired with certified acoustic underlayments (IIC 60+ ratings). We handle all HOA paperwork and property management guidelines seamlessly.

What Affects Bathroom Remodeling Cost in Westside Los Angeles
Bathroom remodeling costs on the Westside depend on the room type, layout changes, subfloor waterproofing integrity, and finish grade. Below are our typical investment ranges including labor, materials, and standard permits:
| Bathroom Remodel Type | Starting At | Typical Range |
|---|---|---|
| Guest Bathroom Remodel | $25,000 | $35,000 – $65,000 |
| Primary / Master Bathroom Remodel | $30,000 | $40,000 – $70,000 |
Every project is different. Your final cost depends on scope, layout changes, materials and finish level, building and HOA requirements, permits, and the existing conditions we find once walls are open. These ranges are starting points, not quotes. The only accurate number comes from a walkthrough.

Skipping Independent Waterproofing Inspections
Tile and grout are decorative, not waterproof. If the hot-mop or membrane beneath is improperly flashed or fails the 24-hour flood test, water will rot structural framing and damage the ceiling below.
Inadequate Ventilation Sizing
Undersized exhaust fans trap moisture, peeling ceiling paint and promoting mildew. We calculate cubic footage accurately and vent exhaust ducts strictly to building exteriors.
Poor Slope Toward Shower Drains
Curbless showers demand exact pre-pitch screeding (1/4 inch per foot minimum). Without precise framing and linear drain recessing, shower water puddles or escapes into the bathroom.
Frequently Asked Questions About Bathroom Remodeling
How much does a bathroom remodel cost in Westside Los Angeles?
Guest bathrooms start at $25,000 with typical projects ranging from $35,000 to $65,000. Primary master bathrooms start at $30,000 with typical projects ranging from $40,000 to $70,000, including labor, waterproofing, custom cabinetry, tile installation, and standard permits.
Can I convert my traditional tub into a curbless walk-in shower?
Yes. Converting to a zero-threshold walk-in shower requires recessing the subfloor framing or installing a ramped dry-pack pan, paired with a linear trench drain and complete floor waterproofing.
What is the difference between microcement and tile in bathrooms?
Microcement is a seamless, grout-free polymer coating that eliminates grout mildew and can be applied over existing sound tile. Traditional tile offers endless ceramic and natural stone styles with individual joints.
How long will I be without my bathroom during renovation?
A standard guest bathroom remodel takes 3 to 5 weeks. If your home has only one bathroom, we phase demolition and fixture reinstallation to minimize days without functional facilities.
Do you manage all plumbing and building permits in Los Angeles?
Yes. Aluna Construction pulls all necessary permits from LADBS or local municipal building departments and schedules the required plumbing, electrical, and shower pan inspections.
