Bathroom Remodel Steps for North Shore Homes

Remodeling a bathroom sounds straightforward until you actually start peeling back the walls of a house built in 1948 and find galvanized supply lines, no vapor barrier, and a floor that's not quite level. After nearly 30 years working on homes throughout Highland Park, Glenview, Winnetka, and the rest of the North Shore, we've learned that a good bathroom remodel isn't just about picking tile—it's about sequencing the work correctly and knowing what's likely hiding behind the walls of a home this age.

Here's how the process generally unfolds.

1. Define the Scope Before You Touch Anything

Start by deciding what kind of remodel you're actually doing. A cosmetic refresh (new vanity, tile, fixtures, paint) is a very different project than a full gut remodel that moves plumbing, reconfigures the layout, or expands the footprint into a closet or hallway. Homeowners in Deerfield and Lake Forest often come to us wanting to convert a tub to a curbless shower or add a second sink—both are great upgrades, but they change the plumbing and electrical scope significantly, which affects both cost and timeline.

This is also the stage to think about who's using the bathroom long-term. Aging-in-place features like grab bar blocking, a wider door, or a zero-threshold shower are far easier (and cheaper) to build in now than to retrofit in ten years.

2. Design and Material Selection

Layout comes first—where the toilet, vanity, and shower sit relative to existing drain lines matters a lot for cost. Keeping fixtures in roughly the same locations keeps plumbing work simpler; moving them means opening up floor joists or a ceiling below, which is common in our two-story colonials and Cape Cods but adds time and expense.

From there you're selecting tile, vanity, countertop, fixtures, lighting, and ventilation. We always push clients toward a quality exhaust fan sized correctly for the room—Chicago's humidity swings between our humid summers and dry, cold winters are hard on bathrooms that are underventilated, and it shows up as peeling paint or mold around the ceiling within a couple years.

3. Permitting

Most municipalities on the North Shore—Highland Park, Glenview, Wilmette, Deerfield, and the others we work in—require permits for bathroom remodels that involve plumbing, electrical, or structural changes. Even a "simple" remodel that relocates a drain or adds a new circuit for a heated floor typically needs sign-off. Requirements and inspection timelines vary by town, and some, like Highland Park, have their own additional review steps for older homes. This is one of the real advantages of working with a licensed general contractor who pulls permits regularly in these towns—we know what each building department expects and how to keep inspections from stalling your project.

4. Demolition

Once permits are in hand, demo begins. This is often when surprises show up—especially in homes built before the 1960s. We regularly find:

• Cast iron drain stacks that are original to the house and due for replacement
• Galvanized supply lines that are corroded or restricting water flow
• Plaster walls instead of drywall, which demo differently and can affect the schedule
• No insulation or vapor barrier in exterior bathroom walls

None of this is a reason to panic—it's just part of remodeling an older North Shore home—but it's worth budgeting a contingency for, and a contractor who's seen it before won't be caught off guard mid-project.

5. Rough-In: Plumbing, Electrical, and Ventilation

This is the unglamorous but most important phase. Plumbing gets relocated or replaced, electrical is updated to current code (GFCI protection, proper lighting circuits), and the exhaust fan ductwork gets run out to the exterior—not just dumped into the attic, which we still find in older homes and always correct. Having plumbers and electricians in-house rather than juggling multiple subcontractors is one reason our projects tend to stay on schedule; there's no waiting around for a trade to become available.

6. Inspections

Rough-in plumbing and electrical typically need to pass municipal inspection before walls close up. This is a checkpoint, not a delay, if the work was done correctly the first time—another reason it pays to have a contractor who does this daily in Lake County and North Shore towns and knows what inspectors are looking for.

7. Insulation, Drywall, and Waterproofing

Once inspections pass, walls get insulated (especially important on exterior walls, given our winters) and closed up. Shower and tub surrounds get properly waterproofed before tile goes on—this step gets skipped by less careful crews and is the single biggest cause of bathroom leaks and mold we get called to fix years later.

8. Tile, Fixtures, and Finishes

Now the visible transformation happens: tile floors and walls, vanity installation, countertop, toilet, shower fixtures, lighting, and mirrors. This is typically the most satisfying part for homeowners to watch, since progress becomes obvious day to day.

9. Final Walkthrough and Punch List

Before we call a project done, we walk it with the homeowner, address any punch-list items, and make sure every fixture and finish meets expectations.

Timeline and Cost Expectations

A full bathroom remodel typically takes several weeks from demo to finish, depending on scope, material lead times, and how many surprises turn up once walls are open. Costs vary widely based on size, lay
