Quick answer: A primary bathroom remodel in Los Angeles typically takes 6–12 weeks total from contract signing to first use — but the actual on-site construction, once permits are approved and materials are on hand, usually takes only 1–3 weeks. The rest of the timeline is design, permitting, and material lead time. APLA Construction (CA Lic #1136359) handles this throughout Greater Los Angeles.
Bathroom remodel timelines in Los Angeles surprise most homeowners for a specific reason: the actual construction — demo through final walkthrough — is usually just 1–3 weeks. What stretches a project to 6–12 weeks total is everything that happens before a single tile is set: design and material selection, permit approval, and material lead time. This guide breaks down exactly what happens when and why, so you can plan realistically. APLA Construction (CA Lic #1136359) manages the complete bathroom remodel timeline for clients throughout greater Los Angeles.
This is the most important planning question for LA bathroom remodels:
Most primary bathroom renovations in Los Angeles require an LADBS permit. The combination of plumbing, electrical, and structural work that defines a real renovation almost always crosses the permit threshold. APLA confirms permit requirements for every bathroom remodel before work begins.
The design phase determines how fast construction flows once it begins. Key decisions that must be made before demo day:
The single most common cause of bathroom remodel delays: tile or fixtures not ordered early enough. APLA establishes material order deadlines for every project at contract signing.
For bathroom remodels requiring a permit, LADBS plan check timelines:
APLA submits for permits immediately after design finalization — running permit review parallel to material lead times compresses the total timeline significantly.
Tile removal, fixture removal, vanity removal, waterproofing membrane removal. Tub or shower demo. In a 65–100 sq ft bathroom, demo typically takes 2–3 days including debris removal. Hazardous material testing (for pre-1980 bathrooms) should happen before demo if tile or drywall may contain asbestos.
New drain and supply line locations roughed in. LADBS rough plumbing inspection required before walls are closed. Inspection scheduling: 24–48 hours after request. Corrections are possible and add 1–3 days.
New electrical circuits (GFCI outlets, lighting, heated floor wiring, exhaust fan). LADBS rough electrical inspection. Most plumbers and electricians can work in parallel during the rough phase.
Cement board or Schluter Kerdi waterproofing system installation on all wet walls. Waterproofing membrane application and cure time (24–48 hours). This phase cannot be rushed — proper waterproofing is the most critical phase for long-term performance.
Floor tile and shower tile installation. Grouting (24–48 hours after setting, to allow mortar cure). Shower tile on a large master bathroom (floor + three walls + shower floor) typically takes 3–5 days of tile setting time. Complex tile patterns, herringbone, or large-format tile requiring back-buttering take longer.
Drywall patching and painting on non-wet walls. Trim installation (baseboards, door casing, window trim).
Vanity installation and plumbing connection. Toilet installation. Mirror and medicine cabinet installation. Plumbing fixtures (faucets, shower system, tub filler). This phase requires all previously ordered fixtures to be on-site — any missing item delays final completion. Adding up Phases 3 through 9 — the actual hands-on construction, from demo through fixture install — a standard primary bathroom typically runs 1–3 weeks total once permits are in hand and materials are on-site. That’s the number that matters once you’ve cleared design and permitting; it’s also why an experienced contractor’s schedule looks nothing like a rough back-of-envelope guess.
Frameless glass shower enclosure installation. Glass is typically fabricated after tile is set (because the exact dimensions must be measured from the installed tile, not the plan). Custom frameless glass: fabrication 2–3 weeks after measurement. Installation: 1 day.
Heated floor thermostat programming, towel bar and accessory installation, exhaust fan wiring and cover installation.
LADBS final inspection (for permitted projects). Punch list completion (touch-up painting, caulk at tile transitions, final cleaning). Occupancy.
For a full gut renovation of a 75–100 sq ft primary bathroom with permit: 6–12 weeks total from contract signing to first use. Most of that time is design, material selection, and permit approval (which run partially in parallel) — the actual on-site construction, once permits are approved and materials are on hand, typically takes just 1–3 weeks.
In order of frequency: (1) Tile or fixture ordered late, arrives after the trade is ready to install; (2) LADBS correction cycle adds 1–2 weeks to permit; (3) Custom shower glass not measured and ordered until tile is done; (4) Trade scheduling gaps between rough and finish phases. APLA proactively manages all four of these with pre-project material audits and coordinated scheduling.
No. Purely cosmetic work (replacing tile in-kind, swapping fixtures in the same location) does not require a permit. Most substantial renovations — anything involving plumbing relocation, new circuits, or structural work — do require a permit. APLA confirms the permit requirement for every bathroom project before work begins.
The most effective way is ordering tile and fixtures before demolition starts rather than after, since material delays are the single biggest cause of schedule slips. Finalizing all design decisions before construction begins also avoids the change-order delays that come with mid-project selections.
