Bathroom Renovation in Smyrna: Planning Guide for Cobb County Homeowners
Smyrna has grown into one of Cobb County’s most active residential markets, with roughly 56,000 residents living in a mix of post-war cottages near the Smyrna Market Village, 1990s builds off South Cobb Drive, and newer townhomes clustered around the Concord Road corridor. The bathroom renovation conversation here is different from intown Atlanta — many Smyrna homes are 30-50 years old, meaning the plumbing and electrical are serviceable but the finishes, fixtures and layouts feel dated. A renovation is usually about modernising a functional bathroom rather than rescuing a failing one.

Start with what works and what does not
Stand in the bathroom and think about what bothers you most. Is it the tiny shower? The single vanity that creates morning bottlenecks? The yellowed lighting? The tile that has seen better days? Make a list of complaints and prioritise them. This becomes the brief for your renovation — it tells you whether you need a full gut or a targeted fix.
Then check the functional systems. Run the shower and listen for gurgling drains. Check if the floor feels solid or has any give near the tub. Look behind the toilet for any signs of past leakage. In Smyrna’s 1970s-80s homes, particularly off Windy Hill Road and Atlanta Road, the original copper supply lines are usually fine, but the drain pipes under the slab can develop cracks after 40 years. If you are renovating a ground-floor bathroom in a slab home, be aware that plumbing access requires cutting through concrete.
Full renovation vs conversion: which makes sense?
Full bathroom renovation ($12,000–$25,000)
A full renovation is the comprehensive approach. The room is stripped to the studs. Old tile, fixtures, drywall and any damaged subfloor come out. New plumbing, electrical, waterproofing, tile, vanity, toilet, lighting and trim go in. The layout can be reconfigured — many Smyrna homeowners use a full renovation to knock out a partition between a separate water closet and the main bath, or to swap a tub/shower combo for a large walk-in shower. This is the right choice when multiple things are wrong, when the layout needs to change, or when you want the bathroom to last 20+ years without further work.
Shower or bath conversion ($4,000–$9,000)
The conversion is the practical upgrade that delivers the biggest visual change for the least money. Keep the layout, keep the plumbing, replace the dominant fixture. In Smyrna, the most common conversion is removing a standard tub and installing a tiled walk-in shower with a frameless glass door — a change that immediately modernises the bathroom’s look and function. The vanity, lighting and toilet can be replaced as part of the same project. A conversion typically takes 5-8 working days.
Half-bath and guest bathroom renovation ($3,000–$7,000)
The powder room is a small space with outsized impact. A new vanity with a stone top, a modern faucet, a good mirror, updated lighting and fresh paint can make a half-bath feel brand new. With no shower or waterproofing to deal with, the project is straightforward and usually done in 2-3 days. It is the easiest renovation win for Smyrna homeowners preparing to sell.
Understanding renovation costs in Smyrna
- Layout changes — moving plumbing is the biggest cost variable. Keeping fixtures in place saves $2,000-5,000.
- Tile — porcelain at $5-15/sq ft installed is the best value. Large-format tile reduces grout lines and labour cost. Natural stone at $25-45/sq ft is beautiful but roughly triples the tile budget.
- Vanity — stock vanities from Smyrna-area suppliers start at $300-700. Semi-custom with quartz tops run $800-2,000. Full custom with premium hardware reaches $3,000-3,500.
- Shower system — a basic showerhead and valve set runs $150-350. A thermostatic shower system with handheld and rainhead runs $500-1,200.
- Glass enclosure — frameless glass is the standard in modern Smyrna renovations: $700-1,500 depending on size and hardware.
- Permits — Cobb County permit fees for bathroom work involving plumbing or electrical run $150-400.
- Contingency — budget 10-15% for unexpected issues. Slab homes may need floor cutting for plumbing access, adding $500-1,500.
Permitting in Smyrna and Cobb County
The City of Smyrna has its own Building Department, separate from Cobb County. If your renovation involves moving or installing new plumbing lines, electrical circuits or structural walls, you need a residential building permit. The Smyrna Building Department accepts applications at City Hall and through its online portal. Inspections are typically scheduled within 3-5 business days. Cosmetic updates — painting, tiling, fixture replacements in the same location — do not require a permit. If your home is in a Smyrna HOA community, check covenants for any renovation approval requirements before starting.
Planning your renovation schedule
- Week 1-2: Design and bidding — settle on layout and finishes, get 2-3 quotes, confirm whether permits are needed.
- Week 3: Paperwork and procurement — file for permits, order materials. Custom items have lead times of 2-4 weeks.
- Week 4: Demolition and rough-in — strip the room, run new plumbing and electrical, install waterproofing. First inspection.
- Week 5-6: Tile and installation — set floor and wall tile, grout, install vanity, toilet, fixtures, lighting.
- Week 7: Finishing — seal grout, paint, install accessories, glass shower enclosure. Final inspection if required.
Full renovations run 6-8 weeks. Conversions finish in 1-2 weeks. In Smyrna’s busy renovation market, expect 3-5 weeks lead time between hiring a contractor and the first day of demolition.
Hiring a renovation contractor in Smyrna
Georgia requires a residential contractor licence for any project over $2,500. Verify through the Georgia Secretary of State. For a Smyrna bathroom renovation, also confirm:
- Current general liability insurance ($500,000 minimum) and workers’ compensation
- 3 references from recent bathroom projects, ideally in Smyrna or the Cobb County area
- An itemised, written contract covering materials, labour, permits and a contingency line
- Milestone-based payments: 30-40% deposit, 30% at rough-in, balance at completion

Frequently asked questions
What is a typical bathroom renovation budget for a Smyrna home?
Full bathroom renovations in Smyrna run $12,000-25,000, conversions $4,000-9,000, and half-bath refreshes $3,000-7,000. Smyrna’s housing stock is mostly 30-50 years old, so costs tend to land in the mid-range — less infrastructure repair than intown Atlanta, but more than brand new construction.
Does the City of Smyrna require a permit for bathroom renovations?
Yes, if plumbing lines, electrical circuits, or structural walls are being moved or added. The Smyrna Building Department handles these. Cosmetic work — paint, tile, fixture swaps in the same location — does not need a permit. Check with your HOA as well, as some Smyrna communities have renovation review requirements.
How do I modernise a bathroom without a full renovation?
A conversion is the answer for most Smyrna homeowners. Replacing a tub with a walk-in shower, swapping the vanity, updating lighting and changing the toilet gives you a bathroom that looks and feels new without the cost and disruption of a full gut renovation. You keep the layout and plumbing, which keeps costs in the $4,000-9,000 range.
What should I do if my bathroom is on a slab?
Many Smyrna homes are built on slab foundations. If your renovation requires moving a shower or toilet drain, the contractor will need to cut through the concrete slab to access and reroute plumbing. This adds $500-1,500 to the project depending on how far the lines need to move. If you keep fixtures in the same location, slab cutting is not needed.
How do I choose a shower system that works for my family?
For daily family use, a thermostatic shower valve with a fixed showerhead and a handheld spray on a slider is the most practical combination. The thermostatic valve keeps water temperature consistent (important for children), and the handheld makes cleaning the shower and rinsing easy. Mid-range options from Delta or Moen run $350-600 and are widely available from Smyrna plumbing suppliers.
Will a bathroom renovation increase my home value in Smyrna?
A well-executed bathroom renovation typically recovers 55-70% of cost at resale in the Smyrna market. The return is strongest for mid-range renovations that match what buyers expect — walk-in showers, modern vanities, good lighting. Over-renovating relative to the neighbourhood can reduce the return, so keep finishes in line with comparable homes in your Smyrna subdivision.
