Dry Bar vs Wet Bar: The Decision That Drives Cost

A dry bar is a counter + cabinetry + appliances (mini-fridge, kegerator, ice maker), no plumbing. A wet bar adds a sink, hot/cold supply lines, and a drain. The cost delta is $1,500–$5,000+ depending on basement plumbing access:

• Plumbing already nearby (basement utility room next door): $1,500–$3,000
• Run new lines through finished ceiling/walls: $3,000–$8,000
• Full rough-in including drain venting: $5,000–$15,000

If the bar is in a basement, the drain often needs an ejector pump (basement floor below the main sewer line). Add $400–$1,200 for the pump + installation.

Electrical Code for Wet Bars

Most US jurisdictions follow NEC requirements:

• GFCI protection for any outlet within 6 ft of the sink (code-mandated).
• Dedicated 20A circuit for kegerator/mini-fridge (so a blender doesn't trip the fridge breaker).
• Dedicated 20A circuit for countertop appliances (blenders, ice makers).
• Separate lighting circuit so a tripped appliance breaker doesn't kill the lights.
• AFCI if the bar is in a finished basement classified as habitable space.

A typical permit-pulled wet bar electrical job runs $800–$2,500. Pulling permits is worth it; unpermitted wet bars can fail a future home inspection and lower resale value.

Kegerator Sizing and Placement

Standard kegerator dimensions (residential):

• Single-tap (1/2 barrel): 24" wide × 24" deep × 33" tall freestanding; built-in versions 33–36" tall to fit under 36" counters.
• Dual-tap: same width or 30" wide for side-by-side keg storage.
• Quarter-barrel (slim): 20" wide × 24" deep × 33" tall.

Critical specs to verify:

1. Front-vent vs rear-vent: built-in installations must be front-vented (rear-vent units overheat in a cabinet enclosure). Almost every problem with a "newly installed kegerator that won't cool" is a rear-vent unit installed in a cabinet.
2. Depth: check the door clearance + drip tray + tap handle when the door opens. A 24" deep cabinet often won't fit a 24" deep kegerator with door swing.
3. Power: dedicated circuit recommended. Compressors draw 1.5–3A continuous; ice makers add another 1–2A.

For draft beer line length: under 6ft to the tap is fine; 6–15ft needs glycol cooling lines ($300–$800 add-on) to keep beer cold all the way to the tap.

Bar Top Height, Depth, and Overhang

Standard residential bar dimensions:

Element	Standard	Range
Bar top height	42"	41–46"
Bar top depth	24"	22–30" (24" most common)
Customer overhang	12"	10–14"
Stool seat height	30"	28–32"
Stool footprint	17" × 17"	16–20" sq
Stool spacing	28" center-to-center	24–32"
Bartender aisle (behind bar)	36"	30–48"
Back bar depth	18–24"	12–30"

The overhang matters: 12" is the comfort minimum. Knees fit under, drinks sit close, elbows have a place. Less than 10" overhang, and bar stools don't pull in properly.

Drainage and Spill Containment

Real bars have a drip rail routed into the bar top edge facing the bartender: a shallow channel that catches overspills. Skipping this on a residential bar means every spill runs onto the bartender's floor mat and (eventually) under the bar cabinet.

Bartender-side floor: anti-fatigue mat + slope-to-drain if you have a floor drain. Without a drain, contain spills with a waterproof floor (tile, sealed concrete, LVT) and a bar mat.

Extended FAQ

Should I get a wet bar or skip the sink? Wet bar if you'll regularly mix cocktails (washing tools, glass rinsing, ice). Dry bar if it's primarily a beverage-and-snack station with pre-made drinks and a kegerator. Wet bars add 2–3× the cost and add resale value to the home; dry bars are 80% of the experience at 30% of the cost.

What ceiling height do I need for a peninsula bar with back bar? 8ft is usable but tight; 9ft is comfortable for tall back-bar shelving and pendant lighting. Pendants hang 30–36" above the bar top, so under 8ft you're choosing between low-hung lights and tall back-bar bottles. Above 9ft, you have full creative freedom.

Where should TVs go relative to the bar? Two layouts work:

1. Behind the bartender (above the back bar): customer-facing, sports-bar feel.
2. Across the room from the bar: bar stools rotate to face TV, more flexible for non-game viewing. Don't put a TV directly above bar customer seats. Neck strain.

Is a draft beer setup worth the hassle? For households that drink beer regularly, yes: a kegerator pays for itself in ~1–1.5 cases of saved beer cost vs cans/bottles, plus better taste. For occasional drinkers, no: beer in a keg goes flat after 4–6 weeks once tapped, and a $1,500 kegerator paying off requires consistent throughput.

What's the ideal bar size for a home with no dedicated room? A peninsula or floating wall bar 6–8ft long, 24" deep, with 2–3 stools facing it. Total footprint ~6×7ft including stool zone, without dominating the room. L-shape and U-shape bars need a dedicated room (10×10ft+).

Can I install a kegerator outdoors? Outdoor-rated kegerators exist (look for "outdoor" or "OUTDR" in model number). Standard indoor kegerators in covered patios void warranty and rust within 1–2 years. Add a covered enclosure with airflow even for outdoor-rated units.

What's the trick to a sturdy bar top? The bar top is what guests touch every visit. Wood: 2"+ thick solid hardwood, 6–8 coats of marine-grade epoxy or polyurethane (counter top wears out twice as fast as kitchen counter from drink rings). Stone: 1.25"+ honed granite or quartz, sealed yearly. Avoid laminate. It bubbles around the sink edge within a few years.

Should the back bar have refrigeration or storage? Both. The back bar's signature design is glass shelves displaying premium bottles + refrigeration below for beer/wine reach-ins. A kegerator centered in the back bar is the residential ideal. Skip mirror back bars unless you commit to weekly mirror cleaning.

How do I plan ice for a home bar? Three options: (1) dedicated ice maker ($1,000–$3,500 for a residential nugget or commercial-style maker, requires plumbing); (2) ice bucket from kitchen freezer (free, requires running back and forth); (3) portable countertop ice maker ($150–$400, no plumbing, makes ice in 15 min). Option 1 if you entertain weekly; option 3 for occasional hosting.

What's the most-overlooked accessory? A glass washer / rinser ($60–$300): a small bar-mounted device that rinses pint glasses with a quick blast of cold water. Saves a trip to the kitchen sink for every glass and is the difference between a "kinda nice home bar" and "pro-feeling home bar."
