Bathroom Remodel Timeline: What to Expect Week by Week in LA

By Onn Cohen Meguri · September 22, 2026 · 9 min read

Our kitchen-timeline post is one of the most-read pieces on this site because every LA homeowner about to remodel wants the same thing: a realistic week-by-week so they know what's coming. So here's the bathroom version. Smaller project, smaller demo footprint, but the internal sequence is denser than a kitchen because of waterproofing and tile — two things that can't be rushed without consequences a year later.

The headline timeline for a standard LA bathroom remodel: 4-6 weeks of construction on site, preceded by 4-8 weeks of pre-construction (design, permits, ordering materials). Powder rooms run shorter. Primary suites with custom showers and freestanding tubs run longer. The week-by-week below is the standard full-bathroom remodel — call out the variations for your specific project below.

Pre-construction (weeks -8 to 0)

Before any crew steps on site, four things have to happen — usually in parallel.

Design + selections — weeks 1-3

Layout decisions, fixture choices, tile selection, vanity, lighting, hardware. Even on a "we're keeping the layout" project, selections alone take 2-3 weeks because of how many components a bathroom has. Tile is the slowest decision; see our bathroom tile materials guide for the comparison framework we walk clients through.

Permit application — weeks 2-4

We submit plans the moment design is locked. Permit timing varies significantly by city:

City of LA (LADBS): 4-8 weeks for plan check on a moving-plumbing bathroom remodel
Beverly Hills: 3-6 weeks
Santa Monica: 4-7 weeks
West Hollywood: 4-6 weeks
Cosmetic-only refresh (paint, fixture swaps, no plumbing relocation): often no permit required

Material ordering + lead times — weeks 2-8

Lead times vary wildly. Standard quartz vanity tops ship in 1-2 weeks from local fabricators. Custom-sized vanities take 4-6 weeks. Imported tile (Italian, Spanish, Portuguese) often runs 6-10 weeks. We order the long-lead items the moment selections are signed off — waiting until permit lands is how projects slip a month.

Pre-construction walk — week 0

We meet on site the week before demo to mark protection routes, confirm fixture locations against rough plumbing, agree on staging areas for tile/materials, and walk neighbors / building managers if it's a condo. Then we start.

Week 1 — Demo + rough plumbing

Day 1-2 is demo: tile, fixtures, vanity, mirror, lighting, sometimes drywall back to studs depending on age of the home. We palletize debris on site and haul off end-of-day so dust containment stays intact overnight.

Day 3-5 is rough plumbing. If we're moving the shower drain, toilet flange, sink supply lines, or adding a freestanding-tub supply, this is when copper or PEX gets routed. In LA's pre-1980 housing stock, this week is where we discover what's actually behind the walls — galvanized pipe that needs to come out, knob-and-tube electrical hiding behind tile, or framing that's not what the original drawings said. Budget 5-10% contingency on any bathroom in a home built before 1970.

A rough plumbing inspection (the city inspector signs off on the open walls) usually happens late Week 1 or early Week 2. The inspector can't be scheduled tighter than 24-48 hours, so the trade sequence has to anticipate this.

Week 2 — Electrical, framing, waterproofing

With plumbing inspected and signed, electrical and framing happen in parallel. New circuits for vanity lighting, GFCI outlets, exhaust fan, in-floor heating if specified, dedicated steam-shower power. Framing changes (niche pockets, bench seats, expanded shower) get locked in.

Mid-week the second rough inspection runs (electrical + framing). As soon as those sign off, we waterproof. This is the most critical step in the entire project and the most commonly cut-corner step on cheap remodels. Standard practice: pre-slope mortar bed on the shower floor, full waterproofing membrane (we use Schluter Kerdi or similar) on shower walls and floor with seams overlapped and corner patches, flood test for 24-48 hours to confirm zero leaks before tile goes down.

A bathroom where the waterproofing was skimped will leak in 2-5 years and require demoing the tile to fix. We've seen it dozens of times in homes built in the early 2000s when "fast and cheap" bathroom remodels were the norm.

Week 3 — Tile (the bottleneck)

Tile is the longest single step in a bathroom remodel and the one most clients underestimate. A full-tile shower with a half-wall and a tiled floor is roughly:

Layout + mortar prep: 1 day
Floor tile install: 1-2 days
Shower wall tile: 3-5 days
Niche detail + accent strip: 1 day
Grout, cure, seal: 2-3 days

That's 8-12 days for a typical tile package. Large-format tile (slab or 24" x 24" porcelain) goes faster on big areas but slower on cuts. Marble or hex mosaics with intricate patterns go slower. Anyone telling you tile will finish in "a couple of days" is either doing a tub-surround spec on a single wall or planning to come back for the rest.

This week is where rushed projects break. Tile that's installed before mortar has cured properly cracks within a year. Grout that's applied before cure-out hazes. Sealing skipped on natural-stone tile produces staining the homeowner notices three months later. Our approach: respect the cure times, don't compress this week.

Week 4 — Fixtures, vanity, paint

Tile cures and seals over the weekend. Monday starts with fixture install: shower valve trim, toilet, faucets, drains, towel bars, toilet-paper holder. Vanity goes in mid-week — the day depends on whether the slab counter was templated against the installed cabinet (most common for built-on-site vanities) or pre-fab (faster install but less custom fit).

Mirror, vanity light, exhaust fan trim, switches and GFCI covers follow. Paint goes on after fixtures so any small fixture-install blemishes get caulked and touched up.

By end of Week 4, the room is visually finished. Looks like a bathroom. Smells like fresh caulk and new tile.

Week 5 — Punch list + final inspections

The last week is finishing work plus inspections. Final fix list (industry term: “punch list”) typically includes: caulk lines that need redoing, paint touch-ups, hardware that needs adjustment, sliding-door alignment, drain adjustments, anything that didn't come out perfect the first time. A real GC walks the punch list with the client and doesn't consider the project done until every item is signed off.

Final inspections: city signs off on the finished plumbing, electrical, and (if applicable) building permits. CO (Certificate of Occupancy) isn't usually issued for a bathroom remodel — it's a permit close-out instead.

Total: 5 weeks of construction. Sometimes 4 if everything goes right. Sometimes 6 if material slips or an old-home surprise eats a week. Real timeline for a real bathroom in LA.

What speeds the timeline up — and what slows it down

Two projects with the same scope can finish three weeks apart based on factors that have nothing to do with the contractor. Things that consistently keep projects on schedule:

Selections locked before construction starts. Indecision on tile, fixtures, or vanity finish is the single biggest cause of timeline slippage. Once we're past Week 2, every selection change adds days because of re-ordering lead times. The fastest projects we run are with clients who decided every material in pre-construction.
Permit submission the day design is finalized. Many clients defer permits until they're "ready" — but a permit sitting in plan check is doing nothing to your house. We submit the moment drawings are approved.
Long-lead materials ordered against estimated permit date, not against permit-issuance. If your tile takes 8 weeks and permit takes 6 weeks, ordering tile when permit lands means a 2-week delay. We order at signoff.
Bathroom cleared the weekend before demo. All personal items, toiletries, medicine cabinet contents, behind-the-toilet storage. Clients who do this themselves save half a day of crew time and avoid breaking a beloved object.
Quick decision on mid-project finds. When demo reveals galvanized pipe or rotten subfloor, a 4-hour client decision keeps the crew working; a 4-day client decision adds 4 days to the project. We provide same-day photos + cost-impact estimate so the call is easy.

Things that consistently slow projects down: HOA approval delays in condos, hillside permit add-ons that surface mid-process, material back-orders (rare but happens with imported tile), and discovered asbestos in pre-1980 homes that requires abatement before demo can continue.

LA-specific factors that affect the timeline

Hillside drainage

Bathrooms in hillside homes (Hollywood Hills, Bel Air upper canyon, Palisades highlands) often need re-routed waste lines, sump pumps, or building-department drainage review. Add 1-2 weeks to permit timing and 2-4 days to construction.

CalGreen low-flow requirements

California Green Building Standards mandate low-flow toilets (1.28 GPF max), low-flow showerheads (1.8 GPM in most jurisdictions), and water-efficient faucets. This rarely affects the timeline but occasionally affects fixture selection — that vintage British showerhead you found may not be legal here.

Condo HOA approvals

Most LA condos require HOA approval for any bathroom work that involves moving walls, changing plumbing locations, or affecting shared-wall waterproofing. Typical HOA approval: 2-6 weeks before permits can even start. Work hours are usually capped (9 AM-5 PM weekdays, no weekends) which compresses crew availability.

Historic preservation zones

Hancock Park, Windsor Square, Highland Park, parts of Pasadena and Pacific Palisades have HPOZ rules. Bathroom interiors are usually exempt (HPOZ rules focus on exterior + structure), but if your project involves moving a window or changing exterior facade, add 6-10 weeks of design review.

Powder room vs standard bath vs primary suite

The 5-week construction timeline above assumes a standard full bathroom — tub or shower, single vanity, toilet. Variations:

Powder room (toilet + small vanity, no shower or tub): 2-3 weeks construction. No waterproofing, no tile floor, no fixture install in a wet zone. Much faster.
Standard ensuite or guest bathroom: 4-6 weeks per the timeline above.
Primary suite rebuild (custom shower + freestanding tub + double vanity + sometimes water closet): 6-10 weeks. Two plumbing zones, more tile, more fixtures, sometimes a steam unit that adds electrical complexity. Custom showers with multiple body sprays push the longest end of that range.

Living through a one-bathroom remodel

In a multi-bathroom home, this is mostly a non-issue. In a one-bathroom home, you have three options:

Hotel/Airbnb during the heaviest weeks (typically Weeks 1-4). Budget $3,000-$8,000 in LA for a 4-week stay nearby.
Stage with a friend or family member who's within driving range. Free, requires logistics.
Stay home with a temporary plan. We can usually keep the toilet functional through most of the project (we install a temporary water shut-off and keep it usable except during direct plumbing work). Shower is more complicated — most clients use a gym shower or a friend's bathroom for 2-3 weeks.

For the broader playbook on staying in your home during construction, the same considerations from our kitchen "living through it" piece apply — dust containment, schedule expectations, communication patterns — just scaled to a smaller footprint.

Total project timeline

Pre-construction (4-8 weeks) + construction (4-6 weeks for a standard bath, longer for primary suite) = 10-16 weeks total from first call to finished bathroom. Add 2-4 weeks for hillside or HPOZ projects. Add 6-10 weeks if you're starting from scratch on a custom layout.

Numbers above assume we order materials and prep permits in parallel; sequential planning adds time. Numbers also assume the client is decisive on selections — material indecision is the single biggest avoidable cause of timeline slippage we see.
