A premium bathroom remodel cost in Miami is set as much by the schedule as by the finishes. On a recent Brickell condo bath — full gut, same layout, Laminam slab walls, Schluter Kerdi waterproofing, frameless glass, Guru USA linear drain — we ran demo to final walk in eight weeks. Cure times do not negotiate. Lead times do not negotiate. The dependency chain was sequenced before the first sledge swing.

This post is the timeline half of our bathroom remodeling in Miami pillar guide. The pillar carries the broad budget bands and the condo-association overhead. This one goes narrow on the eight-week schedule and the dependencies that drive it.

How long does a bathroom remodel take in Miami?

A premium bathroom remodel in Miami takes 6 to 12 weeks from demo to final walk, depending on scope. A cosmetic refresh runs 3 to 4 weeks. A full gut on the same layout runs 6 to 8 weeks. A wet-room or curbless conversion with a layout change runs 9 to 12 weeks. Condo work in Brickell, Key Biscayne, or Miami Beach typically adds 2 to 4 weeks of pre-construction approval before demo can begin.

These numbers assume the finishes are sourced before demo starts. If the Laminam slab is ordered after the substrate is open, the timeline stretches by the four-week manufacturer lead. We do not start projects without the slab, the glass, and the long-lead plumbing trim already specified and on order. That is the single most important decision a homeowner can make to hold the schedule.

Why the Miami schedule is different

Miami bath remodels carry overhead that most national timelines do not capture. The substrate is concrete — usually a post-tensioned condo slab — not wood-framed. Drilling a riser anchor through a tendon is a structural event. Humidity runs 70 to 80% from June through October, which extends every cure time at the edges. Permits in Miami-Dade go through ePlan review with average turnaround of 7 to 14 business days for a residential interior alteration; the Florida Building Code governs the inspection sequence.

Then the condo overhead. Most Brickell, Coral Gables, and Key Biscayne towers require a 30-day association approval window, certificates of insurance from every trade, posted bonds, hours-of-work restrictions (typically 9a–5p Mon–Fri, no weekends), and elevator-protection booking. The full set of association rules is laid out in our deeper read on condo bathroom renovation rules in Miami. None of that overhead is optional. None of it can be parallel-pathed by a contractor who decides to “work around” the rules — the building manager will lock the freight elevator and the project stops.

The eight-week Brickell condo bath — week by week

This is the actual schedule from a recent full-gut bath in a Brickell tower. 90 sq ft floor, 220 sq ft slab walls, single shower with niche, double vanity, frameless glass enclosure. Same plumbing layout. The owner approved finishes four weeks before demo, which is what made the eight weeks possible.

Week	Phase	Critical-path dependency
1	Demo, plumbing rough-in inspection, framing	Building permit issued; HOA approval logged; elevator booked
2	Schluter Kerdi waterproofing, 24-hour flood test	Pan slope set; drain assembly installed; flood test passes
3	Self-leveling underlayment pour, 48-hour cure	Substrate moisture below 75% RH per ASTM F2170
4	Slab wall layout, dry-fit, first panels set	Laminam delivered (ordered week -4); 1.5 mm dry joint mocked
5	Slab walls finish, floor tile, niche, edges	Lippage-controlled with RLS clips; mitered corners pre-cut
6	Grout, perimeter sealant, plumbing trim out	Vanity delivered; mirror template confirmed
7	Glass template, vanity install, fixtures	Glass shop measures (3-week fab clock starts week 4 or earlier)
8	Glass install, punch list, final walk	Final inspection passes; Ivan walks; turnover

Every week passes a dependency forward. Slip one and the chain slides. We schedule a two-day float into weeks 5 and 7 — the high-risk weeks for slab-cut errors and glass template misses — so the eight weeks holds when something goes sideways.

The dependency chain that controls the timeline

The schedule is not a list of tasks. It is a chain of dependencies, each gated by a cure time or a lead time that cannot be compressed.

Waterproofing must cure before tile

The Schluter Kerdi membrane is bonded to the substrate with unmodified thinset. Corners and seams overlap by 2 inches. Pipe penetrations get Kerdi-Seal collars. After the membrane is set, we fill the pan, plug the drain, and run a 24-hour flood test before any tile is allowed near it. ANSI A118.10 is the governing standard. The deeper walkthrough is in our shower waterproofing in Miami guide, and the system comparison is in Schluter Kerdi vs sheet membranes.

The flood test is a hard 24 hours. The waterproofing system is a 3-day cure for full polymerization. We start tile on day 4. Skipping that cure is the most common reason a Miami shower fails at year three with stained corners or efflorescence at the curb.

Substrate flatness must be verified before slab walls

Large-format porcelain panels at 1620 × 3240 mm telegraph substrate flatness like nothing else in residential construction. The TCNA Handbook calls for ± 1.6 mm over 10 ft for tile larger than 15 inches. We hold the wall plane to ± 1.5 mm before any panel is set. If the framing is out, we shim or fur. If the floor needs leveling, we pour self-leveling underlayment and wait the 48-hour cure before tile sets — the field method is in our floor leveling in Miami guide and the moisture protocol is in moisture testing on a Miami condo slab. The flatness math behind the tolerance is in flatness tolerances for large-format tile.

Slab sourcing is a 4-week lead

Laminam, Neolith, and Dekton are not warehoused at residential volume. A custom Calacatta or Nero Marquina pattern from Laminam runs 3 to 5 weeks from PO to Miami port. Container clears, trucking to a Doral slab yard for crate-out, then white-glove delivery to the building. We require the slab on site by Friday of week 3 — which means the PO is cut on day one, often before demo. The sourcing math is in Laminam vs Neolith vs Dekton and the install-side detail in large-format porcelain installation in Miami.

Glass is a 3-week fabrication clock

Frameless shower glass is templated after the tile is set — not before — because the wall is the reference plane. The template runs 30 minutes; the fab clock is 3 weeks for half-inch low-iron with hardware. We start the glass clock at week 4, which puts install at week 7. If the template slips a week, the schedule slips a week. There is no compression here; it is a glass-shop production queue, not a labor question.

Plumbing rough-in must clear inspection before drywall

Miami-Dade requires a rough-in plumbing inspection before any wall is closed. The inspection is scheduled at the end of week 1. A failed rough-in is rare on our work because the plumber walks the rough with us before the inspector arrives — but if it fails, the schedule slips a week minimum.

Bathroom remodel cost in Miami — by scope

The four scope tiers below match the Miami market for premium residential work in 2026. These are turnkey ranges including labor, materials at the spec tier we install, plumbing, electrical, glass, fixtures, vanity, and the condo overhead delta. They do not include design fees, structural engineering for a layout change, or a permit-required plumbing relocation that crosses a unit line.

Scope	Timeline	Budget band (USD)	What’s included
Cosmetic refresh	3 to 4 weeks	$35K to $60K	New tile over existing substrate, fixtures, vanity, mirror; no plumbing move
Full gut, same layout	6 to 8 weeks	$75K to $140K	Demo to studs, new waterproofing, slab or tile walls, glass, fixtures, vanity
Full gut, layout change	9 to 11 weeks	$130K to $220K	All of the above plus plumbing rough-in relocation and structural permit
Wet-room or curbless conversion	10 to 12 weeks	$170K to $280K	Recessed subfloor, single-slope build, linear drain, full wet-area waterproof

These bands assume premium spec — Laminam or Neolith slab walls, Schluter Kerdi waterproofing, Guru USA linear drain, frameless half-inch glass. Off-the-shelf 12 × 24 porcelain with builder-grade fixtures will run 30 to 40% lower. Stone — Calacatta marble or Nero Marquina — runs 15 to 30% higher than premium porcelain because of the slab cost, the longer dry-fit time, and the sealing requirement detailed in honed vs polished marble floors and Calacatta vs Nero Marquina.

The condo overhead delta — association approval, insurance rider, elevator booking, hours-of-work restriction, posted bond — adds 8 to 15% to a same-scope single-family budget. That overhead is real work, not soft cost.

What pulls the schedule earlier — and what does not

Homeowners reasonably ask whether the eight weeks can compress to six. Sometimes yes. Usually no. The levers that work and the levers that do not:

Pre-ordering the slab and glass before demo — this works. We have run a 7-week bath when the slab arrived in week 2 and the glass shop had the fabrication slot open.
Adding a second crew on slab walls — this rarely works. Two crews on the same 220 sq ft of wall step on each other; one trained crew with a clear layout is faster than two.
Skipping the 24-hour flood test — this is not a lever. It is a failure mode. We will not do it.
Compressing the cure on self-leveling underlayment — manufacturer-rated 16 hours under ideal conditions, but Miami humidity pushes it to 24 to 48 hours. We respect the moisture probe, not the bag.
Working weekends in a condo — almost always prohibited by association rules. Coral Gables single-family allows it; Brickell towers do not.
Permit expedite — Miami-Dade ePlan offers expedite for an additional fee on commercial; residential interior alteration does not have an expedite path. The permit clock runs at code speed.

The American Institute of Architects contract documents (A201 and A105) frame the construction schedule with the same logic — substantial completion, punch list, final completion are gated by inspection and cure, not by labor hours. The schedule is a chain, not a sprint.

Common timeline killers in Miami baths

The eight-week schedule fails most often for reasons that have nothing to do with the tile-setting crew.

Finish selection drift. The owner changes the slab pattern in week 3. Lead time resets. Budget the selection lock at the framing stage; do not negotiate it later.
Layout-change requests after demo. Moving a drain or a wall mid-project triggers a structural permit and a re-inspection. Two-week slip minimum.
Glass template miss. If the wall plane is out, the glass shop will not template. Re-flatten and re-template; one-week slip.
HOA paperwork incomplete. Missing certificate of insurance, missing bond, missing approved drawings. The building manager will not unlock the freight elevator. Demo cannot start.
Material damage in transit. A 1620 × 3240 mm slab is fragile in handling. We carry a 5% overage on slab orders. A single cracked panel without overage is a four-week reset.
Layout mistakes in the master bath plan. The vanity-to-glass clearance, the toilet-to-wall offset, the niche placement. The full breakdown is in master bathroom layout mistakes, and the curbless-shower geometry is in curbless shower in a Miami condo.

The NKBA Bathroom Planning Guidelines document the clearance and code minimums; we hold to NKBA on every plan we draw. A bath that meets NKBA on paper still has to meet the slab in the field. Both have to align before glass templates.

When The Miami Floors is the right fit

We are a fit for homeowners and designers who want the schedule, the budget, and the spec to align before demo starts — not after. We work in Brickell, Coral Gables, Key Biscayne, Miami Beach, and Pinecrest. We are Schluter certified. The deeper service breakdowns are at our bathroom remodeling service, Schluter Kerdi waterproofing, large-format porcelain slab installation, custom shower systems, and linear drains.

Ivan personally walks every project before sign-off. The schedule above is not a marketing number — it is the actual sequence we ran on a Brickell condo bath this spring. For a project case in similar context, see our notes on the Brickell condo bathroom renovation. For the broader cluster, the bathroom remodeling in Miami pillar carries the full scope discussion, the condo association deep-dive, and the spec material choices that drive the budget bands above.
