The Building Process of a Bathroom Remodel

A bathroom remodel is one of the most rewarding upgrades you can make to your home. It enhances comfort, increases value, and transforms an everyday space into something functional and beautiful. But behind the finished result is a detailed, step-by-step construction process that ensures everything is built safely, correctly, and up to code.

At S-Line Contractors, we guide homeowners through every phase of their bathroom remodel with clarity and transparency. Whether you’re updating a dated bathroom or designing a spa-like retreat, understanding the building process helps set the right expectations and ensures a smooth experience.

Here’s what the bathroom remodeling process typically looks like from start to finish.

1. Consultation & Planning

The process begins with an in-depth consultation to understand your goals, preferences, and budget.
During this phase, we:

  • Discuss design ideas and layout options
  • Evaluate existing plumbing and electrical systems
  • Identify structural or functional issues
  • Review material preferences and style
  • Create a project timeline

A successful remodel starts with a clear plan.

2. Design & Material Selection

With your goals in mind, we move into the design phase. This includes:

  • Layout planning
  • Fixture and finish selections
  • Cabinet and storage design
  • Lighting and electrical planning
  • Tile, paint, and countertop choices

Selecting materials early helps avoid delays and ensures the design aligns with your vision and budget.

3. Permits & Approvals

Bathroom remodels often require permits for plumbing, electrical, mechanical, or structural changes.
S-Line Contractors handles the entire permitting process, including:

  • Preparing documents
  • Submitting plans
  • Coordinating inspections
  • Ensuring California code compliance

Permits protect your investment and ensure your remodel is safe and legal.

4. Demolition

Once plans and permits are approved, demolition begins.
This includes:

  • Removing old fixtures
  • Taking out flooring and wall tile
  • Disconnecting plumbing fixtures
  • Clearing cabinetry or vanities

We take precautions to protect nearby areas with dust barriers and floor coverings.

5. Plumbing & Electrical Rough-In

After demolition, the structural foundation of your new bathroom begins to take shape.
This phase includes:

  • Installing new water supply lines
  • Updating drain lines
  • Adding or rerouting electrical wiring
  • Installing exhaust fans
  • Setting up lighting and outlet locations

These rough-in systems are inspected before moving forward.

6. Structural Work (If Needed)

Some remodels require structural adjustments, such as:

  • Reinforcing walls
  • Adjusting framing for new shower layouts
  • Expanding bathroom footprints
  • Relocating doors or windows

These updates ensure the space is safe, functional, and ready for finishing.

7. Waterproofing & Preparation

Bathrooms require careful waterproofing to protect against mold and moisture damage.
This step includes:

  • Shower pan installation
  • Waterproof backer boards
  • Sealing joints and seams
  • Moisture-resistant coatings

Proper waterproofing is essential for long-lasting results.

8. Tile Installation

Tile work is one of the most labor-intensive and visually important parts of a bathroom remodel.
This phase includes:

  • Shower wall tile
  • Floor tile
  • Niche installation
  • Decorative borders or patterns
  • Grouting and sealing

Quality tile installation ensures a polished, durable finish.

9. Fixture Installation

Once the tile is complete, we install fixtures such as:

  • Toilet
  • Vanity
  • Sink
  • Faucet
  • Showerhead
  • Tub (if applicable)
  • Mirrors and accessories

This stage brings your design to life and transforms the bathroom into a usable space.

10. Cabinets, Countertops & Finishing Touches

The final touches include:

  • Installing cabinetry
  • Placing countertops
  • Adding lighting fixtures
  • Painting
  • Installing hardware
  • Adding trim and baseboards

Attention to detail ensures everything looks clean, aligned, and intentional.

11. Final Inspection & Walkthrough

Before completing the project, we perform a final inspection to ensure:

  • All systems meet code
  • Plumbing and electrical systems function properly
  • Waterproofing is effective
  • Finishes are clean and complete

Then we walk through the bathroom with you to review the work and address any final adjustments.
