How Long Does a Bathroom Remodel Take? Primary Bath Timelines

Most homeowners ask this question after a contractor has already quoted them "about a month." A month is the marketing answer. The real number depends on tile lead times, shower glass templating, and whether the plumbing rough-in passes inspection on the first try.

We have built more than 500 projects in 16 years across Northbrook, Highland Park, Glenview, Wilmette, and the rest of the North Shore. Primary baths are the second most common job we do. Here is what they actually take.

The Short Answer

A primary bath remodel takes 4 to 8 weeks of on-site work for most North Shore homes. Cosmetic refreshes finish in 2 to 3 weeks. Full gut jobs with a layout change, new shower pan, custom glass, and heated floors finish in 7 to 10 weeks.

That is on-site work only. Add 4 to 8 weeks of design and ordering before anyone swings a hammer. The total calendar from "we should remodel the bathroom" to "we are using it again" is closer to 12 to 16 weeks.

The National Kitchen and Bath Association publishes bathroom planning guidelines that align with these ranges. Industry-wide NAHB data puts the average primary bath at around 6 weeks of construction.

Week-by-Week: What Actually Happens

This is a typical 6-week schedule for a 100 to 150 square foot primary bath. Bigger baths add 1 to 2 weeks. Layout changes add another week.

Week 1. Demo and rough-in.

• Days 1 to 2: protect floors, demo tile, vanity, tub, shower.
• Days 3 to 4: plumber moves drain lines and supply lines if the layout changes.
• Day 5: electrician roughs in lighting, fan, heated floor mat, GFCI circuits.

Week 2. Inspections, then close the walls.

• Day 6: rough-in inspection from the village. Northbrook and Highland Park usually inspect within 2 business days. Wilmette and Winnetka can run 4 to 5.
• Days 7 to 9: insulate, hang drywall, tape and mud first coat.
• Day 10: second mud coat.

Week 3. Tile prep and shower pan.

• Days 11 to 12: third mud, sand, prime.
• Day 13: install shower pan and waterproofing membrane (Schluter Kerdi or equivalent). Flood test for 24 hours.
• Days 14 to 15: lay floor tile.

Week 4. Wall tile and grout.

• Days 16 to 18: shower wall tile. This is where slow tile setters lose days. Large-format porcelain in a herringbone pattern in a Highland Park primary bath we finished last fall took 4 days for two installers. Same square footage in subway took 1.5.
• Days 19 to 20: grout, seal, cure.

Week 5. Vanity, plumbing fixtures, electrical trim.

• Days 21 to 22: install vanity, countertop template (if stone), faucets, toilet.
• Days 23 to 24: stone fabricator returns with the cut counter (10 to 14 days from template).
• Day 25: electrical trim, mirror, sconces.

Week 6. Glass, paint, punch list.

• Day 26: shower glass measure. Custom glass is 10 to 14 days out from measure.
• Days 27 to 28: paint, baseboards, hardware.
• Days 29 to 30: punch list, final clean, walk-through.

The shower glass is the single biggest reason a 6-week job becomes a 7-week job. We measure as early as the schedule allows, but most fabricators will not template until the wall tile is set and grouted.

Where 4-Week Jobs Become 7-Week Jobs

Six things slip primary bath timelines. We have seen each one a hundred times.

• Tile back-order. Imported porcelain from Italy or Spain is 6 to 12 weeks lead time right now. If the homeowner picks tile in week 6 of design, it lands in week 4 of construction. Order tile the day the design is locked.
• Layout change after demo. "Can we move the shower to the other wall" once the walls are open adds 1 to 2 weeks for re-rough-in and a second inspection.

Lead paint in pre-1978 homes. Most North Shore housing stock predates 1978. Federal EPA RRP rules require lead-safe work practices on any home built before then. We are EPA Lead-Safe Certified. The work itself does not slow down. The setup, containment, and HEPA-vacuum cleanup add about half a day per phase.

• Custom shower glass. Standard frameless glass is 10 to 14 days from template. Specialty glass (low-iron, fluted, smoked) is 3 to 5 weeks.
• Stone countertop variability. Quartz is 7 to 10 days from template. Natural stone slab selection adds a trip to a slab yard and another week.
• Inspection backlog. Most North Shore villages are 2 to 5 business days. Evanston and Skokie can stretch to 7 in summer.

Planned vs Actual: Three Real North Shore Primary Baths

Numbers from our last 12 months.

Northbrook, Sunset Ridge. 110 sq ft, frameless glass, heated floor, no layout change. Planned 5 weeks. Actual 5 weeks. Held because tile was pre-ordered in design.

Highland Park, Sheridan Rd corridor. 140 sq ft, layout change, custom fluted glass, marble counter. Planned 7 weeks. Actual 9 weeks. Glass added 2 weeks. Marble slab pick added 3 days.

Wilmette, near Gillson. 95 sq ft, cosmetic refresh, no plumbing moves. Planned 3 weeks. Actual 3 weeks.

The Highland Park job is the cautionary one. The homeowner picked the fluted glass during construction. We told them it would add 2 weeks. They picked it anyway. That is a fair trade as long as the trade is named upfront.

What to Cut to Keep Your Bathroom Remodel Short

If staying short matters more than maximizing scope, cut these in this order.

• Custom shower glass. Standard clear frameless looks the same to most people and saves 1 to 2 weeks plus around $1,500.
• Imported tile. Domestic porcelain is on shelves at Floor and Decor today. Imported is 6 to 12 weeks out. Same look, no wait.
• Layout changes. Keep the toilet, sink, and shower in their current locations. Plumbing rough-in drops from 3 days to 1.
• Natural stone counters. Quartz arrives in half the time and does not stain.
• Heated floors in non-primary baths. Worth it in a primary you stand in barefoot daily. Skip in a hall bath.

When to Start, When to Book the Consultation

A bathroom you want to use by Thanksgiving means design starts in mid-July. A bathroom you want by spring means design starts in November.

The booking sequence we run for every primary bath:

• In-home consultation. 60 to 90 minutes on site. We measure, talk scope, name budget bracket.
• Design and selections. 3 to 6 weeks. Drawings, tile, fixtures, vanity, glass spec.
• Order long-lead items. Tile and glass go first. Vanity and stone next.
• Construction. 4 to 8 weeks per the schedule above.

If you want a real timeline for your specific bathroom, book an in-home consultation. We will tell you the date you can expect to use it again, and what would have to be cut to bring that date in.

You can also see our bathroom remodeling services and a recent Lakewood primary bath project that came in on a 5-week schedule. Most of our porcelain tile work ends up in baths, which is why the tile section of this article is the longest one.

Cut List Takeaway

If you want a 4-week primary bath, pick domestic porcelain on the day design locks, take standard frameless glass, and keep the plumbing where it is.
