How long does a bathroom remodel take? For most St. Louis homes, a full bathroom renovation runs 3 to 6 weeks from demo to final walkthrough. A shower-only replacement is closer to 1 to 2 weeks. A cosmetic refresh — new tile, new vanity, same layout — takes around 2 to 3 weeks.
Those ranges assume materials are on-site before work starts, there are no surprises behind the walls, and a dedicated crew is working through the project consistently.
Two of those three assumptions regularly don’t hold.
This guide covers what actually drives a bathroom remodel timeline, what the phases look like week by week, and where the delays come from — so you can plan around reality, not a best-case scenario.
Bathroom Remodel Timeline by Scope
Not all bathroom remodels are the same job. The scope determines the timeline more than anything else.
Cosmetic Refresh (No Layout Change)
Replacing finishes — new tile, new vanity, new fixtures — while keeping plumbing and walls in the same location. No permits are required in most cases. Timeline: 2 to 3 weeks.
This is faster than most homeowners expect. The work moves quickly when there are no rough-in phases, no inspection holds, and no structural changes.
Full Bathroom Remodel (Same Layout)
Gutting the space and rebuilding — new tile, new plumbing fixtures, new electrical, new waterproofing — while keeping the plumbing in the same location. Timeline: 3 to 6 weeks.
This is the most common bathroom remodel scope we see in St. Louis. The bathroom is completely unusable for most of this window. If it’s your only full bathroom, plan accordingly.
Full Remodel with Layout Changes
Moving the toilet, relocating the shower, reconfiguring the floor plan. This requires permits, rough-in inspection holds, and significantly more coordination between trades. Timeline: 6 to 10 weeks.
Layout changes add time not because the work is harder, but because inspections create mandatory holds. The rough-in inspection has to be passed before walls close — and in a busy market, inspectors can book 5 to 10 days out.
Shower-Only Replacement
Replacing just the shower — new waterproofing, new tile, new fixtures — without touching the rest of the bathroom. Timeline: 1 to 2 weeks in most cases.
This is what we do most often at Tile Gurus. The tile work itself — floor, walls, niche — takes 5 to 7 days. Add time for waterproofing cure, grout cure, and glass lead time.

|---|---|
| Shower-only replacement | 1–2 weeks |
| Cosmetic refresh (no layout change) | 2–3 weeks |
| Full bathroom remodel (same layout) | 3–6 weeks |
| Full remodel with layout changes | 6–10 weeks |
The Phases of a Bathroom Remodel — What Happens When
Understanding the sequence helps you know when to expect what — and where delays actually come from.
Phase 1: Planning and Material Ordering (Before Construction Starts)
This is where most timelines fall apart before work even begins.
Materials need to arrive before the demo starts. Custom tile can run 4–8 weeks from order to delivery. Specialty vanities run 6–12 weeks. Semi-custom shower glass takes 2–4 weeks after measurement. If you start the demo before the tile arrives, you’re paying to have a contractor standing around waiting.
The right sequence: finalize selections, place orders, confirm delivery dates, then schedule the start of work.
For our projects at Tile Gurus, we confirm the tile is on-site before we schedule demolition. It sounds basic — but skipping that step is one of the most common reasons bathroom remodels run weeks over schedule.
Phase 2: Demolition (1–3 Days)
Demo is fast. A crew can gut a standard bathroom — remove tile, pull fixtures, tear out drywall — in one to two days. Larger bathrooms with heavy tile or multiple layers take a day or two longer.
What slows demo down: asbestos testing on older St. Louis homes (pre-1980), lead paint protocols, or discovering that the previous installation was done with thick mortar beds that take extra time to remove.
Phase 3: Rough-In Work — Plumbing and Electrical
If the layout is changing, plumbing and electrical rough-in happen here, before walls close. For same-layout remodels, this phase is minimal.
Rough-in inspection is required before walls can be closed. Inspection availability varies — during busy St. Louis construction seasons, booking can take 5 to 10 days. A failed inspection adds another 3 to 5 days for corrections and re-inspection.
For shower-only projects and cosmetic refreshes, this phase is skipped or minimal.
Phase 4: Substrate and Waterproofing (1–2 Days + Cure Time)
New cement board or backer board goes in. The waterproof membrane goes over the shower walls and floor.
This is the step that determines whether your shower lasts 5 years or 50. Every shower we tile at Tile Gurus gets double-liner waterproofing and a 24-hour flood test before tile goes down. The flood test requires the drain to stay plugged and the shower floor to hold standing water for a full day. That cure window is non-negotiable.
Phase 5: Tile Work (3–7 Days)
Tile work is typically the longest single phase in a bathroom remodel — and the one with the most variation.
A simple subway tile shower surround with a standard floor takes 5 to 6 days, including prep, setting, grout cure, and cleanup. Herringbone floors, custom mosaic accents, large-format wall tile, or multiple tile types in one bathroom take longer — sometimes 7 to 10 days for complex installations.
Grout needs 24 to 48 hours to cure before fixtures can be installed. Shower floors, in particular, need a minimum of 72 hours before any water exposure and 7 days before the shower returns to regular daily use. We build this into the schedule — it’s not a negotiable step.
For a shower tile installation project in St. Louis, the tile phase alone typically runs 5 to 8 days, depending on pattern, material, and scope.
Phase 6: Fixture Installation (1–2 Days)
Vanity, toilet, sink, shower glass, lighting, mirrors, hardware. Everything comes together in this phase — and it’s usually when clients first see what the finished bathroom is going to look like.
Custom shower glass is the item that most commonly delays this phase. Glass companies measure after tile is complete, then fabricate — typically a 2-to-4-week lead time. If the glass wasn’t ordered early enough, fixture installation waits. This is why we coordinate glass ordering as soon as tile selections are confirmed.
Phase 7: Final Plumbing, Electrical, and Inspection
Final connections, test runs, and the final inspection, if one was required. For permitted projects, the inspector needs to sign off before the bathroom can be occupied.
Running showers to check for leaks, flushing toilets, verifying exhaust fans — all of this happens before we call a project complete.
What Causes Bathroom Remodels to Run Over Schedule
Most delays fall into one of four categories.
Materials Ordered Late
The most common delay. A tile that was supposed to arrive in two weeks comes in at five. A vanity that was shown as in stock ships from overseas with a 10-week lead time. By the time the problem is discovered, the crew is already on-site.
The fix: place all orders before scheduling a demo, confirm delivery dates in writing, and have a backup plan if something arrives damaged.
Surprises Behind the Walls
Older St. Louis homes — and much of our service area includes neighborhoods like Kirkwood, Webster Groves, Soulard, and Creve Coeur with housing stock from the early 1900s — regularly reveal unexpected conditions. Subfloor rot from an old leak. Galvanized pipes that need replacement. Mold on the back of the drywall. Out-of-square framing that requires extra work to build a level substrate.
These aren’t contractor failures — they’re hidden conditions that couldn’t be diagnosed without opening the wall. A good contractor budgets time and contingency for discovery. A good homeowner expects some version of this in an older home.
If existing tile or substrate damage turns out to be worse than expected mid-project, our bathroom tile repair approach can sometimes address isolated areas without expanding the full scope.
Scope Changes Mid-Project
Deciding to add a heated floor after the tile is ordered. Changing the shower niche location after waterproofing is done. Upgrading to a different vanity after plumbing is roughed in.
Changes mid-project are expensive in time, not just money. Each change typically adds days — sometimes a week or more — as materials get reordered, work gets redone, and scheduling shifts.
The most time-efficient bathroom remodel is one where every decision is made before work starts.
Permit and Inspection Delays
For permitted projects, inspection availability is outside anyone’s control. Busy seasons in St. Louis — spring and early summer — compress inspector availability. Rural St. Louis County municipalities sometimes run faster than city inspectors. Either way, plan for inspection holds and don’t assume same-week scheduling.
How Tile Work Specifically Affects Your Bathroom Remodel Timeline
Since most of our work at Tile Gurus is tile-focused, it’s worth being specific about what tile choices do to the schedule.
Standard subway tile or large-format porcelain — straightforward layout, solid color — moves the fastest. Expect 5 to 6 days for a full shower surround and floor.
Herringbone, diagonal, or pattern tile — complex cuts, more layout time, slower installation. Add 2 to 3 days.
Mosaic accents, custom niches, or feature walls — each custom element adds time. A mosaic floor can add a full day on its own.
Large-format tile (24×24 and larger) — requires substrate leveling to a 1/8-inch-over-10-feet tolerance, back-buttering every tile, and a leveling clip system during installation. Add 1 to 2 days for prep and install time over standard tile.
Dekton panels — full-slab panels up to 12 feet require specialized equipment and two-person handling. The installation itself moves quickly once the substrate is ready, but the panels have longer lead times. Plan accordingly.
What You Can Do to Keep Your Remodel on Schedule
Most timeline overruns are preventable. Here’s what actually helps.
Order everything before the demo starts. Tile, vanity, fixtures, shower glass measurement (if you can do it), mirrors, hardware. If anything has a lead time over 2 weeks, it needs to be ordered first.
Make all selections before the project starts. Changes mid-project add time. Finalize tile, grout color, vanity, fixtures, and hardware before work begins.
Don’t rush the cure times. Waterproofing flood tests, grout cure time, and shower cure time before water exposure — these aren’t optional steps. Cutting them short creates problems that cost more time and money to fix later.
Schedule inspections early. For permitted projects, reach out to the permit office early and ask about current inspection wait times. In busy seasons, they can surprise you.
FAQs: How Long Does a Bathroom Remodel Take?
A full bathroom gut renovation with the same layout typically takes 3 to 6 weeks. Layout changes that require permit inspections can push the timeline to 6 to 10 weeks. A shower-only replacement runs 1 to 2 weeks in most cases.
Tile work is usually the longest single phase — typically 5 to 7 days for a standard shower surround and floor. Complex patterns, large-format tile, or multiple tile types can push it to 8 to 10 days. Grout needs 24 to 48 hours to cure before fixtures go in, and shower floors need 72 hours before any water exposure.
Late material orders are the most common cause. Surprises behind the walls — subfloor rot, mold, old plumbing — are the second most common. Scope changes mid-project and permit inspection delays round out the list. Older St. Louis homes are particularly prone to hidden conditions.
Cosmetic refreshes — same layout, same plumbing locations — typically don’t require permits. Layout changes that move plumbing or electrical require permits and inspections. If you’re unsure, ask your contractor before work starts — not after.
A shower-only replacement — new waterproofing, new tile, new fixtures — typically takes 1 to 2 weeks. The tile work runs 5 to 7 days. Waterproofing cure, grout cure, and glass fabrication add to the remaining time. Custom shower glass has a 2-to-4-week lead time after measurement.
