Bathroom Remodel Sequence: What Happens When, Week by Week

The real order a bathroom remodel runs in, from demolition through the punch list, and why each step has to happen before the next one.

Demolition comes first, then rough plumbing and electrical while the walls are open, then an inspection before anything closes up, then waterproofing the wet area, then tile, then the vanity, countertop, and shower glass, then fixtures, paint, and a final punch list. The order is not a preference. Each step either has to be inspected before it’s covered, or it has to be built on top of something that has to cure or pass a test first. Skip the order and you either fail an inspection or hide a problem behind tile that has to come back out.

What Happens During Demolition, and What Turns Up Behind a Florida Bathroom Wall?

Demolition strips the room to the studs and slab, and it’s also the first real look anyone gets at what the last thirty or fifty years did to the plumbing, framing, and waterproofing nobody could see. In a lot of Northeast Florida bathrooms, the shower curb and the wall behind it are the first casualty, since a curb that was never properly flashed lets water track into the framing every time someone showers, and by the time the tile comes off there’s soft, dark wood where a solid stud used to be. Older homes still running cast iron drain lines are their own find. Cast iron corrodes from the inside out, and a line that looks fine from outside can be paper thin or already leaking into the subfloor by the time a plumber cuts into it. Long-term leaks around an old tub or shower pan sometimes go deep enough to rot the floor joists underneath, and the fix is sistering, bolting a new joist alongside the damaged one to restore the strength before any subfloor goes back down. None of this is unusual. It’s the reason the schedule always has to leave room for what demolition finds, not just for what the plans show.

Why Do Rough Plumbing and Electrical Happen While the Walls Are Open?

Rough plumbing and electrical happen before anything closes up because it’s the only point in the project where the supply lines, drain lines, and wiring are fully exposed and easy to change. The plumber runs new supply lines and drain piping, the electrician runs wire for outlets, the exhaust fan, and any new lighting, and both trades work off the same open framing at the same stage so nothing has to be reopened later for a line that got missed. Moving a vanity a few feet is a different job from moving a toilet drain, and the difference is what’s underneath the floor. A vanity sink taps into supply and drain lines that usually run inside a wall cavity or a short run under the floor, so relocating one is mostly a matter of extending pipe within the framing that’s already open. A toilet drain in most Florida homes runs through a concrete slab, not a crawlspace, so moving it means cutting the slab, resetting the drain line at the right slope, and pouring the concrete back before the floor goes down. That’s slab work, not just plumbing, and it changes both the timeline and which trades have to be scheduled in what order.

What Has to Pass Inspection Before Anything Gets Closed Up?

The rough-in inspection has to pass before any wall goes back up or any insulation goes in, because the plumbing and electrical work is only visible while it’s still exposed. A county inspector checks the new supply and drain lines, the vent piping, and the electrical wiring and boxes against code before anyone is allowed to cover them with drywall or backer board. If something doesn’t pass, it gets corrected and re-inspected on the spot, and the project doesn’t move to the next stage until it does. This is also why a contractor who tells you the walls are staying open for a few extra days isn’t stalling. They’re often waiting on an inspector’s schedule, not on their own crew.

Why Does Waterproofing Get Its Own Step Instead of Happening Along with Tile?

Waterproofing happens as its own stage, after rough-in passes and before a single tile goes up, because it’s the layer that actually keeps water inside the shower and out of the wall and floor assembly, and tile can’t be trusted to do that job on its own. The wet area gets a sloped pan, built either from a mud bed or a preformed base, and a continuous waterproof membrane over the pan and up the walls, tied into the drain so any water that gets past the grout still has somewhere to go. On a lot of jobs the pan gets a flood test, meaning the drain is plugged and the pan is filled and held for a day, before anyone signs off on it. Once tile goes over that membrane, the room’s ability to shed water for the next twenty or thirty years is already decided, and it can’t be inspected again without tearing the tile back out. That’s why this step gets its own attention instead of getting folded into the tile schedule, and why a crew that rushes it to keep the calendar moving is making a decision that won’t show up as a problem for a few years.

Why Do the Niche and Bench Have to Be Planned Before Waterproofing, Not After?

A shower niche or bench has to be framed and blocked in during rough framing and waterproofed as part of the membrane, because both are physically inside the wall and floor assembly the membrane covers. The niche is a recessed opening built into the stud wall, and its inside corners, back, and shelf all need continuous membrane just like the rest of the shower, which means the framing crew has to know its exact size and position before the wall closes, not after the tile setter shows up. A bench works the same way. It needs its own slope built into the top so water runs off instead of pooling, and that slope has to be shaped and waterproofed before tile ever touches it. If a niche or bench gets added or resized once tile is underway, it usually means cutting back into finished waterproofing to do it right, which is a bigger step backward than most homeowners expect from what looks like a small request.

What Order Do Tile, Vanity, and Glass Go In, and Why Does the Shower Door Arrive Last?

Tile goes in once waterproofing has cured and passed, the vanity and countertop come after the tile floor is down and grouted, and the shower glass is templated and installed last because it’s the one piece that has to be measured against the finished room instead of the plans. A frameless glass installer needs the actual tile surface, the exact curb height, and the real angles of the walls, since even a well-built shower is rarely perfectly square, and glass is cut to fit the room as it exists, not as it was drawn. That means the glass company can’t template until tile is finished, and once they template, the panels still have to be fabricated before they come back for installation. The same logic applies to a stone or quartz countertop. The fabricator templates the cabinet opening after the vanity cabinet is actually set in place, then cuts the counter to that exact measurement before it’s installed. Both steps are why the vanity and countertop feel like they happen quickly and the glass shower door feels like the last thing to show up, sometimes well after the room otherwise looks finished.

Where Do Fixtures, Paint, and the Punch List Fit at the End?

Fixtures, final paint, and the punch list close out the project in that order because each one is easiest to do without something else in the way. The plumber sets the faucet, shower valve trim, and toilet once the vanity and tile are in place, and the electrician installs light fixtures, the exhaust fan grille, and outlet covers around the same stage. Paint touch-ups and any final coat usually happen after the fixtures are set but before the final walkthrough, so nail holes, cabinet chips, or trim marks left from the install get covered rather than covered over and reopened. The punch list is the walkthrough at the very end, room by room, noting anything that still needs adjustment, a caulk line, a door that needs planing, a light that needs re-aiming, before the project is considered complete.

Does the Sequence Change If a House Only Has One Bathroom?

Yes, because a house with one bathroom has to plan around living without it during the weeks the room is unusable, while a house with two bathrooms can keep one available the entire time. In a one-bathroom home, the stretch from demolition through waterproofing and tile is the hardest part to work around, since that’s when the room genuinely cannot be used at all, and homeowners in that position often plan to stay elsewhere for part of the project or lean on a half bath if the house has one. In a two-bathroom house, remodeling one at a time means the household always has a working bathroom, which takes the pressure off the schedule and lets each stage, especially the inspection and waterproofing cure time, run at a normal pace instead of getting rushed.

Understanding the order a bathroom remodel runs in is useful on its own, but it matters most once you already know what kind of project you’re planning. If you haven’t settled whether your bathroom needs a cosmetic refresh, a full gut, or a layout change, that decision comes first and shapes how much of this sequence you’ll actually go through. If you’re weighing more than one proposal for the same project, it helps to know what to compare once the scopes don’t match. And if part of the goal is a bathroom that works for the next twenty years, not just the next five, it’s worth reading about what aging-in-place remodeling actually changes before the walls close for good.

A design-build bathroom remodel keeps demolition, plumbing, waterproofing, tile, and finish work under one schedule instead of a chain of separately hired trades, which is what keeps a sequence like this one from drifting.
