A basement bar is the most personal room in the house, which is why generic idea lists don't help much. This guide is different: every bar below is one Built by Design finished in Overland Park, Olathe, Lenexa, Leawood, Shawnee, or Parkville, photographed after the homeowners moved in. Each one answers a real question: how much of the basement should the bar claim, does it need a sink, where does the wine go, how many people should sit at it, and what makes it look like it belongs to the house.
Use the ideas to decide what your bar has to do. Then use the numbers in the last sections to make sure it works.
The bar is one decision inside a larger plan. Read how to plan a basement remodel in Johnson County for headroom, egress, and permits, and what a finished basement costs in Kansas City for the budget side.
The word "bar" covers three very different projects. A dry bar is cabinetry, a counter, a drink fridge, and no plumbing; it can go almost anywhere. A wet bar adds a sink, which means a drain and a supply, and in a basement the drain has to reach the sewer line or an ejector pump. A basement kitchen adds a dishwasher, full-height refrigeration, and often a microwave or a range, and it starts to need the same electrical and ventilation thinking as the kitchen upstairs. BBD's documented basements include all three. Most are wet bars with a dishwasher and beverage refrigeration, because the homeowners wanted to host a whole evening downstairs without trips upstairs. Two are full basement kitchens. Decide which one you're building before anyone draws a cabinet, because the plumbing and electrical rough-in happens weeks before the counters arrive.
| Type | What it needs | Choose it when |
|---|---|---|
| Dry bar | Cabinetry, counter, a drink fridge on its own circuit | The kitchen is close, or the sewer line is far and you want to skip a pump |
| Wet bar | A sink with a drain and supply, dishwasher optional, refrigeration, GFCI receptacles | You host downstairs and want cleanup to stay downstairs |
| Basement kitchen | Sink, dishwasher, full-height refrigerator, microwave or range, ventilation, more circuits | Frequent guests, long weekends, or a future suite |
The layouts below are the ones that come up again and again in BBD's basements. Each entry names the project, what the bar included, and the decision that made it work. Open the case study for the full photo set and the recorded timeline.
The most common BBD layout. The bar sits where people arrive, the lounge and the screen are in view, and nobody walks through the movie to get a drink. Overland Park's blue bar with brass hardware, wine storage, and a wood-paneled island is the clearest example: island seating faces the lounge, and the sink, dishwasher, microwave, and beverage fridge stay on the working side.
When the household hosts often, one bar becomes a bottleneck. One Overland Park basement solved it with a kitchen-style wet bar near a dining-height table and a separate beverage station with a dual-zone drink fridge and open bottle display, so guests pour their own while the host works. Recorded construction: 9 weeks.
For frequent guests, two BBD basements went all the way: a sink, dishwasher, drink fridge, and a wood island with seating in Overland Park; a wet bar kitchen with a range, microwave, and drink fridges in Olathe. The tell is the island, which turns the bar into a place to eat. Plan the circuits and the ventilation like a kitchen.
The Overland Park basement with a walk-in wine cellar puts glass doors and wall-mounted racks beside a wet bar with a marble-look waterfall island and a geometric tile wall. The cellar is a display as much as storage, so it gets its own lighting and a glass door rather than a solid one. Recorded construction: 16 weeks.
Smaller than a walk-in but the same idea: one Overland Park basement built a glass-door drink cellar with wall racks, glassware storage, and dark herringbone tile beside a dark wet bar with brass hardware. It keeps bottles visible and dust-free, and the glass keeps the theater lounge feeling open.
In Lenexa, stored vintage art and decor set the direction: a reclaimed-look wood bar island with a dark counter, stacked stone feature walls, floating shelves with display lighting, and leather stools. The bar is warm rather than glossy because the collection is.
The Parkville basement has a built-in theater bar behind the seating, so guests can set a drink down and stay with the screen, and a back wet bar with appliances, a stone-look backsplash, and a blue island for serving and cleanup. Two bars, two jobs, no walls between them. Recorded construction: 13 weeks.
Shawnee's bar is gray cabinetry, white counters, brass pulls, a geometric tile backsplash, a sink, a dishwasher, beverage and full-height refrigeration, and a TV above the backsplash. It sits beside the theater lounge so game day and movie night happen at once. It's the right size for a basement that also needs a game room, a bathroom, and an office. Recorded construction: 14 weeks.
Storage is where bars get undersized. Count what you actually keep: bottles of wine, cans and mixers that need refrigeration, spirits that don't, and glassware. Then choose the storage that fits the count, not the photo. BBD's basements show the full range. Vertical wine storage built into the cabinetry in Leawood. A dual-zone drink fridge and open bottle display in Overland Park. Wall-mounted racks behind glass in a drink cellar. A walk-in cellar with its own lighting. The decision that matters most is refrigeration: an under-counter beverage fridge holds cans and a few bottles; a dual-zone unit holds wine at two temperatures; full-height refrigeration turns the bar into a kitchen. Each one needs its own circuit, and the cellar needs a plan for temperature if it holds anything you'd mind losing.
A bar that seats two is a counter. The ones people gather at seat four or more and leave room to stand behind the stools. The National Kitchen and Bath Association's planning guidelines are the reference most designers use: allow 24 inches of counter width per seated person, 15 inches of knee depth at a 36-inch counter (12 inches at a 42-inch bar height), and a 36-inch walkway behind the stools so people can pass while someone sits. On the working side, a 42-inch aisle lets one person work without bumping the fridge door into the island. The island bars in BBD's basements seat four to five on the lounge side and keep the sink, dishwasher, and fridge on the other. That's the geometry to copy: seating faces the room, work faces the wall.
A wet bar is a plumbing project first. The sink drain has to reach the house's sewer line, which leaves the basement below the slab at one point. If the bar sits near that point, the drain runs in a trench in the slab. If it doesn't, the bar needs an ejector pump, a pit, a vent, and an alarm, or a small sink pump. Find the line before you place the bar; it can move the bar ten feet and save a pump. Electrical is the other half. Refrigeration, a dishwasher, a microwave, and lighting each want their own circuit, and receptacles within 6 feet of the sink need GFCI protection under the residential code Johnson County cities adopt. A basement kitchen with a range adds ventilation. All of it goes on the permit drawings, and the rough-in gets inspected before drywall. BBD's bars are built with the same trade partners named in each case study, and the plumbing and electrical rough-in lands in weeks 3 to 5 of a typical basement schedule.

The bars that read as custom rather than kit share a pattern: one saturated color or one strong material, and everything else quiet. Blue cabinetry with brass hardware in Overland Park and Lenexa. Dark cabinetry with a white geometric tile wall. Natural wood with stone-look counters in Olathe. Reclaimed wood and stacked stone in Lenexa. A marble-look waterfall island against a geometric tile wall in Overland Park. On the practical side, quartz-style counters take spills and glass rings; a backsplash that runs full height behind the sink is easier to clean than paint; and light wood-look plank flooring, which appears in most BBD basements, handles moisture better than solid hardwood on a slab. Floating shelves with under-shelf lighting do double duty as display and task light.
Every bar photo people save has three kinds of light: pendants over the counter that mark the bar as a place, lit shelves or a lit cellar that make the display glow, and recessed lighting on a dimmer so the whole thing can drop to movie-night levels. Put the pendants on their own switch, the shelf lighting on another, and the room lights on dimmers. The Olathe basement with a rope-style LED fixture over the pool table and globe pendants over the bar is the pattern at its clearest.
Built by Design's previously published basement range is $80,000 to $550,000, and the bar is one of the scope decisions that moves a project within it. A dry bar is cabinetry and a fridge. A wet bar adds plumbing, and an ejector pump if the sewer line is far. A basement kitchen adds appliances, circuits, ventilation, and an island. Wine cellars add glass, racks, and lighting, and a conditioned cellar adds cooling. The basement cost page breaks the full range down by scope; the bar is part of the "bar or kitchen" line.

FAQAnswers, by design
The questions homeowners ask about basement bars, answered from the fourteen basements BBD has built and the planning guidelines designers use. Your project team confirms what applies to your lower level.
Yes. The sink drain, the supply lines, and the circuits for refrigeration and a dishwasher are plumbing and electrical work, and they are inspected at rough-in as part of the basement permit in Overland Park, Leawood, Lenexa, Olathe, Shawnee, and Parkville. A dry bar with only cabinetry and a plug-in fridge may not, but the basement finish around it usually does.
Allow 24 inches of counter per stool, a 36-inch walkway behind the stools, and a 42-inch aisle on the working side. A four-seat island bar with a back bar behind it takes roughly 8 feet of counter and a footprint about 10 feet deep including the aisles. A compact wet bar along one wall can fit in 6 to 8 feet of length.
Yes. A dry bar with cabinetry, a counter, and a beverage fridge on its own circuit skips the drain entirely, which is the right call when the sewer line is far away or the kitchen is at the top of the stairs. You lose downstairs cleanup, which is why most BBD bars include a sink and a dishwasher.
It depends on the type. A dry bar is cabinetry and a fridge; a wet bar adds plumbing and possibly an ejector pump; a basement kitchen adds appliances, circuits, and ventilation; a wine cellar adds glass, racks, lighting, and sometimes cooling. Built by Design's published basement range is $80,000 to $550,000, and the bar or kitchen is one of the scope lines that moves a project within it.
Near the stair and out of the theater's sight line. That's where the bar sits in nearly every BBD basement: guests reach it without crossing the screen, and the host can see the room. Put the sink and appliances on the wall side and the stools on the lounge side.
Quartz-style surfaces take spills, glass rings, and bottle drops better than most, and they show up on most BBD bars. A full-height backsplash behind the sink is easier to clean than paint. Wood tops look right on a rustic bar, as in Lenexa, but they need sealing and care.
