The week-by-week shape of a full gut
| Stage | Working time | The hidden wait |
|---|---|---|
| Demolition | 1–3 days | Dumpster scheduling; discovery repairs. |
| Plumbing & electrical rough-in | 3–5 days | Rough-in inspection before walls close. |
| Backer board & waterproofing | 2–3 days | Membrane cure times — chemistry, not hustle. |
| Tile (floor, walls, shower) | 4–8 days | The most labor-intensive stretch. |
| Paint & trim | 1–2 days | — |
| Vanity, toilet & fixtures | 2–3 days | Everything must already be on site. |
| Shower glass | install: half a day | Measured AFTER tile; 2–4 week fabrication. |
| Punch list | 1–2 days | The faucet that arrived wrong in week one. |
Add it up and the tools-on-site total is 15–25 working days. The calendar disagrees because three waits don't compress:
- The shower glass trap. Custom enclosures are measured off the finished, tiled shower, then take 2–4 weeks to fabricate. That's a built-in tail on every custom-glass bathroom — the room is 95% done and unusable for a month. Mitigations: a standard-size enclosure off the shelf, or living with a rod and curtain while the glass is cut.
- Inspections gate the schedule. Rough-in can't be covered until it's inspected, and inspectors book days out. A missed Friday slot is a lost long weekend.
- Waterproofing cures on its own clock. Good tile setters won't rush it, and you don't want the one who would.
What makes a 5-week bathroom take 10
- Materials that aren't on site at demo. The single biggest cause. A vanity is 2–6 weeks out; special-order tile is 2–6 weeks out; a fancy faucet finish can be 4. If the crew starts while those are still shipping, the schedule is a hope, not a plan — work the ordering timeline backward so everything lands before day one.
- Mid-project changes. Moving a drain a foot after rough-in reopens finished work and re-queues the inspection.
- Discovery. Bathrooms hide the house's worst secrets — soft subfloor around the toilet, corroded galvanized supply lines, missing venting. This is what the contingency budget is for; the schedule needs its own contingency of about a week.
- Trade scheduling gaps. Plumber, electrician, tiler, glazier — four trades, four calendars. Every handoff is a potential idle day, which is why a packed material staging area and a confirmed sequence matter more than raw crew speed.
The one-bathroom household question
If it's your only bathroom, the calendar math changes life: budget for 3–5 weeks without a shower, not "a couple of days." Options people actually use: sequence the work so the toilet is out of commission for the shortest possible window (good crews can keep it functional most nights), a gym membership for showers, or timing the project against a vacation week. This is a planning input, not an afterthought — decide it before demo, not during.
The pattern behind every fast bathroom: every item on site before demo, every approval decided before rough-in. The remodels that finish in four weeks aren't the ones with the fastest crews — they're the ones where nobody ever stood around waiting for a box.
