Most bathroom remodels in the Gwinnett County area land somewhere between $9,000 and $28,000, depending on whether you’re refreshing finishes or gutting the room down to the studs. A full guest bath renovation typically falls in the $9,000–$15,000 range, while a primary bathroom with a walk-in shower, double vanity, and new plumbing runs $18,000–$35,000 or more.
Those numbers vary more than people expect, and the reason usually isn’t the tile you pick — it’s what’s hiding behind your existing walls.
What Actually Drives the Price
Homeowners tend to budget around finishes: tile, fixtures, vanity style. Those choices matter, but three other factors move the needle more.
1. Plumbing Relocation
Moving a toilet, shower, or vanity even a few feet can add $1,500–$4,000 to a job because it usually means opening the floor and rerouting drain lines. Keeping fixtures in their existing footprint is the single biggest way to control cost.
2. Homes Built Before the Mid-1990s
A large share of the bathrooms we remodel around Lawrenceville, Snellville, and Duluth are in homes built in the 80s and early 90s. These often have galvanized supply lines, cast iron drains, or subfloor water damage that isn’t visible until demo starts. We build a contingency of 10–15% into most quotes for exactly this reason — it’s not padding, it’s realistic.
3. Waterproofing Standards
Modern code and best practice call for a proper waterproof membrane system in showers — not just tile over cement board. Skipping this to save money is the number one cause of the leaks and mold issues we get called to fix in five- and ten-year-old “budget” remodels. It adds cost upfront but prevents a much bigger bill later.
Typical Cost Breakdown by Scope
- Cosmetic refresh (paint, new vanity, new fixtures, same layout): $5,000–$9,000
- Mid-range remodel (new tile, tub-to-shower conversion, new vanity/plumbing fixtures): $12,000–$20,000
- Full gut renovation (layout changes, new plumbing runs, custom shower, heated floor): $22,000–$40,000+
Where Georgia Homeowners Get the Best Return
Walk-in showers consistently deliver the best combination of daily usability and resale appeal in this market, especially in primary bathrooms. Double vanities are the second most requested upgrade we see, particularly from buyers in the $400,000+ range shopping in Gwinnett and Forsyth counties.
How to Keep Your Bathroom Remodel on Budget
- Keep the existing plumbing footprint wherever possible
- Choose porcelain tile over natural stone — it looks similar at a fraction of the material and maintenance cost
- Get a licensed contractor to inspect for water damage before you finalize a budget, not after demo starts
- Set aside a contingency fund — 10% minimum for homes over 20 years old
Frequently Asked Questions
Is a bathroom remodel worth it in Georgia’s housing market?
Yes — bathroom remodels typically recoup 60–70% of their cost at resale in the Atlanta metro area, and they’re consistently one of the top factors buyers cite when comparing similar listings.
How long does a full bathroom remodel take?
A mid-range remodel usually takes 3–4 weeks from demo to final walkthrough. Full gut renovations with layout changes can run 5–7 weeks, largely depending on tile lead times and inspection scheduling.
Do I need a permit to remodel a bathroom in Gwinnett County?
If you’re moving plumbing, changing electrical, or altering the layout, yes — a permit is required. Cosmetic-only updates like new paint or a vanity swap in the same location typically don’t require one.
