One of the most common questions we hear from homeowners considering a bathroom renovation is: "How long will I be without a bathroom?" It's a reasonable question — bathrooms are not optional, and planning around their unavailability requires knowing the real timeline.
The honest answer: it depends on scope and circumstances. But here's a detailed breakdown of each phase so you can build realistic expectations for your specific project.
The Short Answer by Scope
| Scope | On-Site Construction Time | Total Elapsed Time | |-------|--------------------------|-------------------| | Cosmetic refresh (no permit) | 1–2 weeks | 3–5 weeks | | Full hall bathroom renovation | 2–4 weeks | 6–12 weeks | | Master bathroom renovation | 3–6 weeks | 8–16 weeks | | Master bath — complex tile/custom | 5–8 weeks | 12–20 weeks |
"Total elapsed time" includes planning, material ordering, permitting (if required), and construction. "On-site construction time" is how long your bathroom is actually torn apart.
Phase 1: Planning and Selections (2–4 weeks)
Before any work starts, decisions need to be made: tile, fixtures, vanity, shower configuration, lighting. The time this takes depends almost entirely on you — a homeowner who comes in with clear selections can move to construction quickly. A homeowner still deciding between three tile options at week four slows everything down.
What speeds this up: Visiting tile showrooms early, making selections before signing a contract, having a clear budget range that filters options naturally.
What slows it down: Changing selections after the contractor has ordered materials. This is one of the leading causes of project delays.
Phase 2: Permitting (if required)
Not every bathroom renovation requires a permit. Here's the rule of thumb:
- No permit needed: Replacing tile in the same location, swapping a vanity without moving plumbing, painting, new fixtures in the same location
- Permit required: Moving any plumbing, adding electrical outlets or circuits, upgrading the exhaust fan (often requires electrical permit), structural changes
For projects requiring a permit in the City of Los Angeles (LADBS):
- Simple over-the-counter permit: 1–3 days
- Plan check (more complex scope): 4–8 weeks
This is the phase most responsible for the gap between "signed contract" and "demo starts." If your project requires plan check, budget time accordingly.
Practical note: In most jurisdictions, you cannot legally begin permitted work until the permit is in hand. A contractor who starts demo before permits are issued is cutting a corner.
Phase 3: Material Procurement (1–6 weeks)
Some materials are readily available; others take time:
- In-stock tile (home improvement store or tile shop): Available same week
- Specialty or imported tile: 2–6 weeks lead time
- Stock vanities (IKEA, Home Depot): Available same week
- Semi-custom vanity: 3–5 weeks
- Frameless glass shower enclosure: 2–4 weeks after measurement (measurement happens after tile is done)
Glass is almost always the last thing that gets ordered — it's measured off the finished tile and fabricated to exact dimensions. The gap between "tile is done" and "glass is installed" is typically 2–3 weeks. This is the most common source of timeline extension at the end of a bathroom project.
Key decision: If you want tile from a specialty supplier, order it the day the contract is signed, not when demo starts. Having tile on-site before demo begins eliminates the material wait.
Phase 4: Demolition (1–2 days)
Demo is fast. Stripping an existing bathroom to studs — removing tile, backer board, toilet, vanity, and fixtures — takes 1–2 days for a standard bathroom. What it reveals is unpredictable.
Common discoveries during demo in LA homes:
- Rotted studs or subfloor behind original tile (water infiltration over time)
- Mold
- Galvanized supply lines that need replacement
- Undersized or deteriorated drain lines
Budget $1,500–$5,000 contingency for substrate repair. If you're renovating an older home that hasn't had a full bathroom gut in 30+ years, the probability of finding something unexpected is high.
Phase 5: Rough Work (2–5 days)
If plumbing or electrical is moving:
- Rough plumbing (relocating drain lines, supply lines): 1–2 days
- Rough electrical (new circuits, outlets, GFCI, exhaust fan): 1–2 days
- Required inspections before closing walls: add 1–3 days for scheduling
Phase 6: Waterproofing and Backer (1–2 days)
Before tile sets, a proper waterproofing membrane is installed over the entire wet area. A liquid-applied membrane (like RedGard) needs 24–48 hours to cure. A sheet membrane (Schluter Kerdi or similar) can be tiled over same-day in most cases.
This phase is often rushed on lower-quality projects. It's one of the places where careful contractors differentiate from careless ones.
Phase 7: Tile Setting (3–8 days)
This is the most variable phase in a bathroom renovation:
- Simple 12x24 porcelain, floor and shower walls: 3–4 days for an average bathroom
- Large format tile (24x48): 4–6 days — requires extra care on floors (lippage control) and walls
- Mosaic accent patterns or intricate layouts: 5–8+ days
- Floor-to-ceiling tile in multiple patterns: 6–10 days
Tile work cannot be rushed. Setting tile at proper pace ensures full adhesive coverage and prevents lippage (uneven tile edges). Setting tile too fast is a quality shortcut that shows in the finished product.
Phase 8: Grout and Cure (2–3 days)
After tile is set, adhesive needs to cure — typically 24 hours before grouting. Grout then needs 24–72 hours to cure before use. This is non-negotiable chemistry: rushing curing time produces cracked or staining-prone grout.
Phase 9: Fixtures and Finish (2–4 days)
Installing toilet, vanity, countertop, faucets, shower fixtures, mirrors, accessories, and trim. This phase moves quickly once the tile and surfaces are complete.
Phase 10: Glass Install (Day 14–21 after tile completion)
The glass is measured after tile is complete, custom fabricated, and installed. This is where most projects gain their final 2 weeks. Plan for it.
What Causes Projects to Run Long
Selections not made in advance: Waiting to choose tile after demo starts adds 1–4 weeks.
Custom or backordered materials: Specialty tile, custom vanities, or backordered plumbing fixtures add lead time.
Permit delays: Plan check at LADBS or other city departments can take 4–8 weeks for complex scopes.
Substrate discoveries during demo: Rotted substrate or mold remediation adds 3–7 days.
Weather during finish work: Grout and caulk don't cure properly in very cold or very humid conditions. This matters less in LA than in most climates, but some winter weeks still cause delays.
Multiple decision changes: Every change after work begins adds time. Making tile, fixture, and layout decisions before demo starts is the single best way to keep your project on schedule.
