A bathroom remodel is easier to understand when you view it as a series of dependent steps rather than one long construction project. The finish selections may get the most attention, but the work behind the walls has to happen first. Plumbing, electrical, framing, ventilation, waterproofing, and inspections all need to be addressed before tile, paint, mirrors, and fixtures can be installed.
The exact bathroom remodel order of work varies with the scope. A cosmetic update may skip demolition and rough-ins entirely, while a full remodel that moves plumbing or changes the layout will involve more stages. Still, most complete bathroom renovations follow the same general progression: plan first, build the hidden systems next, then install finishes and fixtures last.

1. Start With Planning, Measurements, and Selections
The first work in a bathroom remodel happens before anyone removes a tile. Start by identifying what needs to change: the layout, storage, shower size, lighting, accessibility, ventilation, plumbing condition, or overall appearance. Measure the existing room carefully and determine whether the planned fixtures will fit while preserving comfortable clearances and usable door swings.
This is also the time to make major decisions that affect construction. For example, changing a tub to a shower, moving a toilet, adding recessed lights, widening a doorway, or installing a larger vanity can change the plumbing, electrical, framing, and permitting needs.
Choose the key materials early, especially items with fixed dimensions or longer lead times:
- Bathtub or shower base
- Shower valve, trim, and showerhead
- Vanity and countertop
- Toilet
- Tile and grout
- Flooring
- Lighting and exhaust fan
- Mirrors, medicine cabinets, and accessories
A clear scope protects the sequence of work. It also helps prevent a common problem: discovering after rough plumbing is complete that the selected vanity, shower fixture, or mirror requires a different location, size, or backing. For a broader pre-construction checklist, review this home renovation checklist before the project begins.
2. Handle Permits, Scheduling, and Material Ordering
Before demolition, confirm whether the project requires permits or inspections. Requirements vary by municipality and by scope, but relocating plumbing, adding circuits, changing ventilation, or altering walls may require approvals. A qualified contractor can help identify the applicable steps for the project location.
Materials should be ordered before the room is taken apart whenever practical. It is particularly important to verify that the tub, shower pan, vanity, specialty tile, faucets, and light fixtures are available. Construction can sometimes proceed while finish materials are in transit, but missing essential components can create unnecessary pauses later in the schedule.
The project schedule should also account for the order in which trades need access to the room. Plumbers and electricians generally need open walls. Tile installers need completed, stable, waterproof substrates. Fixture installation must wait until surrounding finishes are ready.
3. Prepare the Home and Complete Demolition
Once the plan is set, the work area is prepared. This can include protecting floors along travel paths, containing dust, creating a debris route, and identifying where tools and materials will be stored. In a one-bathroom home, it is especially important to plan for temporary bathing and restroom arrangements before the old fixtures are removed.
Demolition usually includes removing the existing vanity, toilet, tub or shower components, flooring, wall tile, drywall, and other finishes within the scope. Water and electrical power are shut off or disconnected as needed. Careful demolition can reveal conditions that were not visible before, such as water damage, mold-like staining, deteriorated subflooring, outdated plumbing, or framing issues.
If the bathroom has signs of active moisture damage, the source should be corrected before new materials are installed. Covering a problem with new tile or paint can lead to larger repairs later.
4. Repair Framing and Build the New Layout
After demolition exposes the structure, the room can be repaired and reshaped. This phase may include replacing damaged subflooring, correcting framing, building a shower curb or niche, reinforcing walls for grab bars, and adding blocking for towel bars, mirrors, shower doors, or wall-mounted vanities.
If the design changes the footprint of the room, framing work may also involve moving nonstructural partitions or modifying door openings. Structural changes require additional care and should be evaluated appropriately before work begins. The goal at this stage is to create a solid, square, and properly supported base for all of the systems and finishes that follow.
5. Complete Rough Plumbing, Electrical, and Ventilation
“Rough-in” refers to the behind-the-wall portion of mechanical work. It comes before drywall, tile, and finished fixtures because access is still open.
Plumbing rough-in
The plumber installs or adjusts water supply lines, drain and vent piping, shower valves, tub connections, and toilet or sink locations. If fixtures are moving, this is the phase where the new layout becomes real. The exact rough-in height and placement should be coordinated with the selected vanity, sink, shower system, and wall tile plan.
Electrical rough-in
The electrician installs wiring, electrical boxes, switches, outlets, lighting connections, and circuits needed for the project. This is the right time to add practical upgrades such as vanity lighting, shower lighting where appropriate, a dedicated outlet, or a properly controlled exhaust fan.
Ventilation rough-in
Bathrooms need effective moisture management. If a new fan, duct route, or vent termination is part of the work, it is generally addressed during this stage. The fan housing, ducting, and electrical connection need to be coordinated before the ceiling is closed.
6. Pass Required Rough Inspections, Then Close the Walls
When permits apply, rough plumbing, electrical, mechanical, or framing inspections typically occur before the walls are covered. Scheduling these inspections at the correct point helps avoid the cost and disruption of reopening finished surfaces later.
After required approvals, insulation can be installed where needed. Drywall goes in on dry areas, while shower and tub-surround areas receive a suitable tile backer or other approved substrate. The materials used in wet locations matter: standard drywall alone is not an appropriate tile substrate inside a shower enclosure.
Drywall finishing, sanding, and priming may occur before or after some tile work depending on the project plan. The important point is that wall surfaces must be properly prepared before finish materials are applied.
7. Waterproof the Shower and Install Tile or Other Finish Surfaces
Waterproofing is one of the most important stages in a tiled shower. The waterproof layer belongs behind or on the shower substrate, depending on the system being used. It should be completed before tile is installed, not treated as an optional extra after the fact.
Once wet areas are ready, tile installation can begin. Shower walls are usually tiled before the shower floor is completed, though methods vary. Floor tile, wall tile, niches, benches, curbs, grout, and sealant details must be sequenced so that joints are clean, surfaces are protected, and needed curing time is respected.
Bathroom flooring is often installed after wall work to reduce the chance of damage, but the order can change based on the vanity design. A freestanding vanity may sit on top of finished flooring. A built-in cabinet arrangement may be installed before certain floor finishes. Discuss the plan before installation so there is no confusion about where the finished floor will begin and end.
8. Install the Vanity, Paint, and Finish Trim
When floors, walls, and tile are sufficiently complete, the vanity or cabinetry can be set. Countertop installation may follow after the cabinet is secured and measured. At this stage, painters can complete final coats on walls and ceilings, while carpentry work can address baseboards, door casing, trim, and any remaining backing or decorative details.
It is normal for some tasks to overlap. For instance, painting may be completed in stages around tile installation, and trim may wait until flooring is in place. A well-managed project coordinates these details to avoid damaging finished work or requiring unnecessary touch-ups.
9. Finish With Fixtures, Accessories, and Final Checks
The last major phase is commonly called “trim-out” or final installation. The room starts to look complete because the visible, usable components are installed:
- Toilet
- Sink and faucet
- Shower trim, showerhead, and tub spout
- Light fixtures, switches, and outlet covers
- Exhaust fan grille
- Mirror or medicine cabinet
- Towel bars, robe hooks, toilet paper holder, and other accessories
- Shower glass or shower rod
- Caulk and sealant at appropriate transitions
Final checks should include testing the plumbing for leaks, confirming drains flow correctly, operating the fan and lighting, checking doors and drawers, reviewing grout and caulk lines, and ensuring the shower enclosure functions as intended. If a final inspection is required, it is generally scheduled after the permitted work is complete and accessible for review.
What Can Change the Typical Bathroom Remodel Sequence?
Not every bathroom project follows the exact same order. The sequence may change when:
- The bathroom has hidden water damage or a weakened subfloor.
- Plumbing needs to be relocated or updated.
- A wall is moved, removed, or added.
- Custom cabinetry, shower glass, or stone countertops require field measurements.
- Tile patterns, large-format materials, or specialty finishes need extra preparation.
- Inspection timing affects when walls can be closed.
- The bathroom remains partially in use during construction.
Some phases also require waiting. Mortar, grout, paint, waterproofing products, and sealants may need to cure before the next step. Trying to force the schedule can compromise the finish or lead to callbacks.
How Homeowners Can Help Keep the Work Moving
Homeowners do not need to manage each trade, but timely decisions make a real difference. Finalize selections before work begins, keep fixtures and tile available when scheduled, and avoid late layout changes after rough-ins are complete. If a change is necessary, discuss how it affects cost, schedule, materials, and related work before authorizing it.
It also helps to understand that quality bathroom work is not just about the last day of installation. The durability of the finished room depends on the less visible stages: sound framing, correct plumbing, safe electrical work, proper ventilation, and a reliable waterproofing system.

Frequently Asked Questions
What is the first thing to do in a bathroom remodel?
The first step is planning the scope, layout, budget, and material selections. Once those decisions are clear, permits and material orders can be addressed before demolition begins.
Should you install the vanity before or after bathroom flooring?
Either approach can be appropriate. Freestanding vanities are often installed on top of finished flooring, while some built-in cabinet plans may be installed before flooring. The best sequence depends on the vanity type, flooring material, and design details.
Does tile go in before or after the shower fixtures?
The behind-the-wall shower valve and plumbing are installed before tile. The visible shower trim, showerhead, and tub spout are installed after tile and other surrounding finishes are complete.
When should a toilet be installed during a bathroom remodel?
The toilet is typically one of the final fixtures installed, after the flooring is complete and the room is ready for final plumbing connections.
Plan the Sequence Before the First Tile Comes Out
A successful bathroom remodel follows a practical order: decisions and approvals first, demolition and behind-the-wall work next, waterproofing and finishes after that, and fixtures at the end. Understanding that sequence helps homeowners ask better questions, anticipate temporary disruption, and recognize why certain steps cannot be rushed.
