The question arrives in the same words every time: wet bar or dry bar? The answer is a plumbing question wearing a design question’s clothes. A dry bar is cabinetry: a counter, closed storage below, open or glass-fronted shelving above, bottle and glass storage, perhaps a beverage fridge. A wet bar is the same thing plus a sink — and the sink brings water supply, a drain, usually another electrical circuit, and in Mississauga often a building permit. Nearly everything else that matters — where it goes, how big it is, what the workshop builds — follows from that one decision.
Both are projects we build routinely as bars and entertainment units, in the same Mississauga workshop as the kitchens; this guide is the thinking behind the first conversation.
What each one needs
| Dry bar | Wet bar | |
|---|---|---|
| Plumbing | None | Hot and cold supply plus a drain to the stack; a pump if the drain cannot run by gravity |
| Electrical | An outlet for a beverage fridge and lighting, often existing | Usually a dedicated circuit for the fridge, dishwasher drawer or ice maker; GFCI protection near the sink |
| Permit (City of Mississauga) | Normally none for cabinetry and counters | A plumbing fixture added and drainage installed are permit-required; new circuits need an ESA permit |
| Counter | Any material; no wet area | A material that shrugs off water at the sink — quartz is the usual answer |
| Best spot | Anywhere a wall and an outlet allow | Within reach of the existing stack or a bathroom wall, or the drain run drives the cost |
| Built by | Workshop cabinetry, installed by the crew | Workshop cabinetry plus licensed plumbing and electrical trades, coordinated on one schedule |
The permit line is the one people miss. The City’s permit-required list names a plumbing fixture that is added, removed or relocated and plumbing drainage that is installed, replaced or repaired as permit work; a sink replaced in the same location is not. A new wet-bar sink where no sink existed is therefore usually a permit, priced as its own line, exactly as it is for a kitchen — our permit guide has the full list.
Where the sink can go decides the bar
In a basement the question is distance to the stack. A wet bar on the wall that backs onto the basement bathroom, the laundry or the main stack is a short supply run and a gravity drain. A wet bar on the far wall of a finished rec room may need the slab opened for a drain or a pump to lift waste to the stack — possible, but the point at which a dry bar with a beverage fridge starts to look sensible. If the basement is being made into a legal second unit, the unit’s kitchen already carries the plumbing and the bar is usually dry.
Upstairs, a wet bar next to a dining room or a family room follows the same logic with a kitchen wall as the nearest water.
Layout and dimensions that work
Bars are built from kitchen components, so kitchen dimensions apply. Base cabinets are about 24 inches deep and the counter finishes at roughly 36 inches; a raised ledge for bar stools sits around 42 inches, with 24 inches of ledge width per stool and 12 inches of knee space under it. Upper cabinets or shelving start about 18 inches above the counter. A serving run of 6 feet is enough for a sink base, a fridge opening and a stretch of counter; 8 to 10 feet gives room for a dishwasher drawer or wine storage. The 3D design settles the numbers around your room and the stools you actually buy; nothing is cut until you approve it.
Equipment comes first in the drawing, not last: the beverage fridge’s dimensions and ventilation gap, the ice maker’s drain, the position of the outlets and the cable route for a TV above the bar are decided before manufacture, which is how the entertainment units avoid the on-site surprises that flat-pack bars collect.
What the workshop builds
Bar base and wall cabinetry, serving counters, display shelving, bottle and glass storage, beverage-fridge openings and wine storage are the catalogue items. Because the boxes are built here, a bar can match the kitchen doors upstairs exactly, run wall to wall without filler strips, and hide the pump or the water lines in a panelled back. Decorative panels, lighting and cabinetry beside a fireplace come with their own clearances and safety requirements, which are designed to rather than around — the custom millwork side of the business. Quartz is the usual counter for a wet bar for the same reason it is the Mississauga default in kitchens: non-porous and indifferent to spills, as the countertop comparison explains.
Choosing
Choose a dry bar when the wall is far from water, the budget wants to go into cabinetry and finishes rather than plumbing, or the basement already has a kitchen or bathroom sink within a few steps. Choose a wet bar when the stack is close, you entertain enough to want glasses washed where they are used, or the bar will double as a kitchenette. Either way, plan the sink base, the rough-in and a circuit at the design stage if there is any chance you will want them later; it costs little now and a wall later. Then request a quote with a photo of the wall and the distance to the nearest drain — that single measurement answers the question faster than any guide.
Frequently asked questions
What is the difference between a wet bar and a dry bar?
A wet bar has a sink with running water and a drain; a dry bar has no sink. A dry bar is cabinetry, a counter, bottle and glass storage and perhaps a beverage fridge; a wet bar adds plumbing supply and drainage, usually an extra electrical circuit, and sometimes a permit.
Does a wet bar need a permit in Mississauga?
Adding a plumbing fixture and installing drainage are on the City of Mississauga's permit-required list, so a new wet-bar sink where none existed usually needs a building permit; replacing a sink in the same location does not. New electrical circuits need an Electrical Safety Authority permit filed by the licensed electrician.
How deep and how tall should a home bar be?
Standard base cabinets are about 24 inches deep and finish at roughly 36 inches with the counter; a raised serving ledge sits around 42 inches for bar stools. The exact dimensions are set by the room and the stools you buy, which is why the design is drawn in 3D before anything is cut.
Can a dry bar be converted to a wet bar later?
Yes, if the cabinetry leaves a sink base and the wall allows the supply and drain run. Deciding at the design stage is cheaper: a sink base, a rough-in and a circuit can be planned now and used later.
Where should a beverage fridge go?
In a cabinet opening sized to the model, with the ventilation gap the manufacturer specifies and its own outlet on a suitable circuit. Fridge dimensions and clearances are measured before manufacture so the opening fits the appliance you own.
