Before day one: 2 to 8 weeks of planning
The clock most homeowners track starts at demo. The clock that actually matters starts when you sign the contract. Design finalization, permit submission, materials ordering, and scheduling all happen before a single tile comes down.
Custom tile, shower glass, and non-stock fixtures drive lead times. If you're picking a semi-custom shower system, expect 3–5 weeks from order to on-site delivery. Full-custom tile and glass push that to 6–10 weeks.
- Design + selections: 1–3 weeks
- Permit application to approval: 2–6 weeks (jurisdiction-dependent)
- Materials lead time: 2–10 weeks (biggest variable)
- Contractor scheduling: 2–8 weeks out from signed contract
Week 1: Demo, rough plumbing, framing
Demo takes 1–2 days for a standard bathroom. Everything comes out to the studs and subfloor. This is when hidden surprises surface - rotted subfloor, cast-iron drain corrosion, out-of-code wiring - that trigger the change orders every homeowner dreads.
Rough plumbing and framing happen in the same week: shower valve rough-in, drain relocation if any, blocking for grab bars and vanities, subfloor patching. Electrical rough-in follows: vent fan, GFCI outlets, LED lighting.
- Days 1–2: Full demo, haul-off, subfloor inspection
- Days 2–3: Framing changes, blocking, plumbing rough-in
- Days 3–4: Electrical rough-in, vent fan install
- Day 4–5: Rough inspection (in permitted projects)
Week 2: Waterproofing, shower base, cement board
Tile showers require full waterproofing - either a sheet-membrane system (Kerdi, Wedi) or a liquid membrane (RedGard, Hydro Ban) - over cement board or a pre-formed foam wall panel. This work has to dry between coats.
Acrylic shower systems skip most of this: the walls are the waterproofing. That's the big timeline gap between acrylic (1–3 days total for the shower) and tile (7–10 days just for the shower).
- Days 6–8: Cement board / foam panel install
- Days 8–10: Waterproofing membrane, dry time between coats
- Day 10: Shower pan or acrylic base install
Week 3: Tile, grout, fixture install
Tile floor and shower walls: 2–4 days depending on tile size and pattern. Mosaic and small-format tile take longer. Grout goes down 24–48 hours after tile, then needs 24–72 hours to cure before sealer.
Fixtures, glass, and finish work land at the end: toilet, vanity, mirror, faucet, shower valve trim, glass measurement (glass is usually 5–10 more days after measurement because it's fabricated to the finished opening).
- Days 11–13: Tile install
- Day 14: Grout
- Days 15–16: Vanity, toilet, fixture install
- Days 17–18: Paint, trim, punch list
- Days 19–20: Final inspection, shower glass measurement
Typical total by project type
These are professionally-installed, permitted timelines. DIY runs longer.
- Tub-to-shower conversion (acrylic, existing footprint): 3–5 days
- Walk-in shower replacement (acrylic): 5–10 days
- Walk-in shower (tile, custom): 2–3 weeks
- Full remodel (layout unchanged, acrylic shower): 2–3 weeks
- Full remodel (layout unchanged, tile shower): 3–5 weeks
- Full gut remodel (new layout, tile): 5–8 weeks
- Add 2–4 weeks for shower glass if custom
| Project | On-site time | Typical add-ons |
|---|---|---|
| Tub-to-shower, acrylic, same footprint | 3–5 days | Glass +5–15 days |
| Walk-in shower replacement, acrylic | 5–10 days | Glass +5–15 days |
| Walk-in shower, tile custom | 2–3 weeks | Glass fabrication |
| Full remodel, layout unchanged, acrylic | 2–3 weeks | - |
| Full remodel, layout unchanged, tile | 3–5 weeks | Glass +5–15 days |
| Full gut, new layout, tile | 5–8 weeks | Permit re-inspection |
What actually causes delays
Materials backorders top the list - natural stone, imported tile, and specific fixture finishes. Permit turnaround is second. Homeowner change orders after work starts are third, and they compound because each change triggers re-scheduling of the affected trades.
- Materials backorder (natural stone, imported tile, specific finishes)
- Permit turnaround in slow jurisdictions
- Change orders mid-project
- Hidden damage found at demo (rot, mold, out-of-code wiring)
- Custom shower glass fabrication (5–15 business days)

Frequently asked questions
Can I still use my only bathroom during the remodel?+
Not usually. Even a 3-day tub-to-shower has 1–2 days where the plumbing is off. Plan for a hotel, a friend's spare bathroom, or a portable toilet rental if it's your only bathroom.
Why does a tile shower take so much longer than acrylic?+
Tile requires waterproofing that has to dry between coats, then tile install, then grout that needs to cure, then sealer. Each phase has mandatory wait time, and no crew can speed it up without risking failure. Acrylic wall panels are pre-manufactured and pre-waterproofed, so install is just seaming and sealing to the pan.
Should I pick acrylic to save time?+
If timeline is your top priority and you're happy with acrylic's look, yes. If you want the look of large-format tile or natural stone, budget the extra weeks - the aesthetic difference is real. There's no way to "speed up" a tile install without shortcuts that shorten its lifespan.
How far in advance should I book a contractor?+
Reputable contractors are typically booked 4–12 weeks out. Kitchen and bath remodelers in busy markets can be 12+ weeks out during spring and summer. Book earlier than you think you need to.
