Average Team Size for a Bathroom Renovation

A standard bathroom remodel typically involves 5 to 8 different specialists if you hire professionals. In a full-scale renovation, the team might look like this:

RoleTask

General Contractor Manages the project, coordinates trades

Plumber Installs and updates pipes, fixtures

Electrician Handles wiring, lighting, outlets

Carpenter Builds walls, installs cabinets, framing

Tiler Installs floor and wall tiles

Drywaller Repairs or installs drywall

Painter Prepares and paints walls/ceilings

Installer Mounts vanities, mirrors, glass enclosures

Some contractors or handypersons may cover multiple roles (e.g., a carpenter who also paints), but for a quality remodel, you’ll often have a minimum of 5 professionals involved.

1. General Contractor (GC) – The Project Manager

Headcount: 1 person or team
DIY Alternative: The homeowner manages the coordination

A GC oversees the entire renovation. They hire schedules, supervise subcontractors, obtain permits, and ensure everything is done to code.

If you want a smooth process without managing people or materials, a GC is essential.

2. Plumber – The Hidden Hero

Headcount: 1–2 plumbers
DIY Alternative: Not recommended unless you’re experienced

Any bathroom remodels will involve moving or replacing plumbing fixtures, such as toilets, sinks, and bathtubs. This can include rerouting pipes, installing new shut-off valves, and ensuring proper drainage to prevent issues.

A licensed plumber ensures your water lines and drainage systems comply with local building codes.

3. Electrician – Safe and Certified

Headcount: 1 licensed electrician
DIY Alternative: Possible only for basic tasks if permitted

Upgrading a bathroom usually involves new:

GFCI outlets
Vanity lights
Exhaust fans
Heated floors (optional)
Light switches and dimmers

For safety and code compliance, always use a licensed electrician, especially when modifying circuits or installing fixtures near water sources.

4. Carpenter – The Structural Specialist

Headcount: 1 carpenter
DIY Alternative: Homeowners can handle minor framing or vanity installation

If your bathroom remodel includes:

Moving walls
Building custom vanities
Installing cabinets or doors
Framing a new tub or shower enclosure

…a carpenter is crucial for structural work and precise measurements.

5. Tiler – The Finish Work Expert

Headcount: 1–2 tile installers
DIY Alternative: Doable for experienced DIYers

Tiling is one of the most labor-intensive parts of a bathroom remodel. It includes:

Floor tile
Shower walls
Backsplashes
Waterproof membranes and grout

Professional tilers can complete the job more quickly and accurately, ensuring watertight seals and long-term durability.

6. Drywaller and Painter – Polishing the Look

Headcount: 1–2 individuals
DIY Alternative: Many homeowners DIY drywall and paint

After demolition and rough-in work, you’ll need drywall repair and moisture-resistant paint. A skilled drywaller can ensure a smooth finish, and a painter will use proper primers to prevent mold and mildew.

7. Installer or Finisher – The Final Touches

Headcount: 1–2 people
DIY Alternative: Yes

This role handles finishing elements, such as:

Installing vanities and mirrors
Mounting shelves or towel bars
Installing glass shower doors
Hanging hardware or accessories

While this may seem simple, precision is crucial for a professional look.

DIY Bathroom Remodel: How Many People Do You Need?

If you’re a capable DIYer, you could do much of the remodel yourself, but you’ll still likely need help for specific specialized tasks.

Minimum DIY Team:

TaskPerson Needed

Demolition 1–2 people (yourself and a helper)

Plumbing DIY (basic) or hire a plumber

Electrical Hire licensed electrician (required in most places)

Tiling DIY or hire if complex patterns

Painting DIY

Finish work DIY

You may only need 2–3 people total (including yourself) for a partial remodel or refresh.

Can One Contractor Do It All?

Some handyman services or renovation companies offer “design-build” packages, where one team handles everything from design to execution. These teams typically include:

Project manager
In-house plumber/electrician
Tile installer
Cabinet and counter installers

In this case, you still have multiple specialists, but they’re all under one company umbrella, reducing coordination issues and delays.

Why It’s Important to Have the Right Team

The quality of your remodel depends not just on materials but on the skill and coordination of your team.

Risks of Cutting Corners:

Leaks from poorly installed plumbing
Electrical hazards or code violations
Mold from bad waterproofing
Uneven tile work
Delayed inspections and failed permits

Hiring fewer people to save money often ends up costing more in repairs later.

How Many People = How Long?

Generally, more hands on deck means faster work—but only if well-coordinated. A well-managed team of 6–8 specialists can finish a remodel in 3–4 weeks, while a solo DIYer may take 2–3 months or more.

Final Thoughts

So, how many people does it take to renovate a bathroom?

Professionally: You’ll need 5–8 specialists, each playing a crucial role.

DIY: You might get away with 2–3 people but may still need licensed help for plumbing and electrical work.

The number of people ultimately depends on Your Budget

Whether it’s a complete gut or simple update
