Introduction
A bathroom remodel has more steps — and more ways to do them in the wrong order — than its small footprint suggests. Tiling before the plumbing inspection, ordering fixtures after demolition, closing walls before the electrician signs off: each sequencing error costs money or time. This checklist puts every step in order, from first measurement to final walkthrough, with the budget checkpoints that keep spending under control.
Estimate each phase as you plan it with the Bathroom Remodel Cost Calculator — the component breakdown maps directly onto these steps. The complete guide covers the estimating method behind the numbers.
Phase 1: Plan and Budget
- Measure the room. Floor dimensions, ceiling height, fixture zones, door/window/plumbing locations — written down, in one unit system. The measurement workflow is in the estimating guide.
- Freeze the layout. Decide now whether plumbing moves; each relocated drain adds $2,000–$5,000+.
- Build the component estimate. Fixtures + tile + waterproofing + plumbing + electrical + labor + 10–20% contingency.
- Set the fixture tier. Budget, mid-range, or premium — and price real listings, not memories.
- Check permit requirements. Call the local building department (AHJ) before finalizing scope — see the code compliance guide.
- Get three itemized contractor quotes. Compare line by line against your estimate.
Phase 2: Procure
- Order fixtures and tile before demolition. Confirm lead times in writing; special orders can take 4–8 weeks.
- Buy 10–15% extra tile (20% for diagonal/mosaic), all from one dye lot; keep a spare box after the job.
- Confirm the shower valve model now — it goes in the wall before tile, and changes after waterproofing are expensive.
- Size the exhaust fan: CFM = sq ft × 1.1 (metric: m² × 11.84), rounded up; confirm the duct route vents outdoors.
- Pull permits. Have approved permits in hand before demolition day.
Phase 3: Demolish and Rough-In
- Demolish. Shut off water first; protect anything staying; budget $200–$500 for disposal.
- Inspect the opened walls. Look for rot, mold, and outdated plumbing or wiring — this is what the contingency is for. Document with photos.
- Rough plumbing and electrical. New drains, supplies, circuits, GFCI, fan wiring — all before any wall closes.
- Add grab-bar blocking ($50–$150 now) and any in-wall niches or framing changes.
- Rough-in inspections. Pass plumbing and electrical inspection before closing walls — the pro tips guide explains why this hold point matters.
Phase 4: Close, Waterproof, and Tile
- Close walls with moisture-appropriate board (cement backer in wet areas).
- Install waterproofing membrane in the shower/wet zone ($400–$1,200 typical); flood-test the shower pan if applicable.
- Tile floors first, then walls. Verify layout lines before the first tile is set.
- Grout and seal (seal natural stone; confirm cure times before use).
Phase 5: Finish and Inspect
- Install fixtures: vanity, toilet, shower trim, faucets — then test every valve, drain, and flush.
- Install fan, lighting, mirrors, and accessories. Confirm the fan actually moves air outdoors.
- Paint and caulk. Use moisture-resistant bathroom paint; caulk tub/shower joints with silicone, not grout.
- Final inspection and walkthrough. Punch-list every defect before final payment — drips, grout gaps, fan operation, hot/cold orientation.
- File warranties and keep spare tile. Register fixture warranties; store that spare box of tile and leftover paint.
Budget Checkpoints
| Checkpoint | Question to answer |
|---|---|
| After Phase 1 | Does the estimate sit inside the scope band (e.g., $10k–$25k for a full bath)? |
| After Phase 2 | Are fixture prices locked at real (not estimated) numbers? |
| After demolition | Did hidden damage consume contingency? Re-forecast before proceeding. |
| Before tile | Any change orders priced in writing and signed? |
| Before final payment | Is every punch-list item resolved? |
Documents to Keep on File
Keep a project folder — physical or digital — with the signed contract and itemized scope, all permits and inspection sign-offs, fixture model numbers and warranties, the tile dye-lot number and spare box location, and every change order priced and signed before work proceeded. At resale, this folder answers every question a buyer’s inspector asks.

Frequently Asked Questions
What is the correct order of a bathroom remodel?
Plan and budget → procure fixtures → demolish → rough plumbing/electrical → inspections → close walls → waterproof → tile → install fixtures → finish → final inspection. Never tile or close walls before rough-in inspections pass.
When should I order fixtures?
Before demolition. Special orders take 4–8 weeks, and the shower valve must be on site before waterproofing and tile begin.
How much extra tile should I buy?
10–15% over measured area for standard layouts; 20% for diagonal, herringbone, or mosaic. One dye lot, and keep a spare box.
When do inspections happen?
Rough-in inspections (plumbing, electrical) before walls close; a final inspection after finishes. Covering uninspected work risks tearing it open.
How long does a typical remodel take?
3–6 weeks of active work for a full bath once materials are on site; 6–10 weeks for primary baths or wet rooms. Add fixture lead times before demolition.
What should I check at the final walkthrough?
Every valve and drain, toilet flush, hot/cold orientation, fan operation and exterior venting, grout and caulk lines, and paint finish — before releasing final payment.
One Page, One Pass
Print this checklist and run through it the week before demolition, then again the morning each phase starts. The five minutes it takes per checkpoint catches the mistakes that cost five figures — a fixture that doesn’t fit the rough-in, an inspection nobody booked, a material that never arrived. Checklists don’t slow projects down; surprises do.
