Kitchen Rough-Ins Before Cabinet Installation: Burlington, Hamilton & Waterdown Checklist

Cabinet installation goes more smoothly when the services behind the cabinets have already been coordinated with the final layout. Plumbing, electrical, ventilation and appliance locations should be reviewed against the cabinet plan before boxes are fixed to the walls.

Use one coordinated kitchen plan

The cabinet drawing, appliance schedule and trade rough-ins should refer to the same layout. Moving a sink, range or refrigerator after rough-in can create unnecessary rework. For the broader sequence, see Kitchen Cabinet Order of Operations for Burlington and Waterdown.

Plumbing

Confirm the sink cabinet location, sink type and dishwasher relationship before plumbing work is finalized. Plumbing should be positioned so it can be accessed and connected without unnecessarily cutting structural parts of cabinet boxes. Exact requirements depend on the fixtures, appliances and site conditions.

Electrical

Kitchen electrical work must be planned around the final appliance and cabinet layout. Outlets, appliance connections, lighting and any in-cabinet or under-cabinet electrical requirements should be coordinated by the appropriate qualified trade and comply with applicable requirements.

Ventilation

Range hood planning affects the upper cabinet zone. Confirm the hood type, manufacturer clearances and duct route before ordering the surrounding wall cabinets. The range hood and upper cabinet planning guide covers this interface in more detail.

Appliance dimensions

Use manufacturer documentation for the refrigerator, range, dishwasher, microwave and hood. Do not rely only on the marketing width shown in a product name. Installation openings, ventilation gaps and connection zones can differ by model. ShopKitchens also maintains an appliance cabinet collection for cabinetry designed around appliance zones.

Before cabinets arrive

• Verify finished wall dimensions.
• Confirm the final appliance schedule.
• Compare plumbing locations with sink and dishwasher positions.
• Compare electrical locations with appliances and cabinet features.
• Confirm hood and duct routing.
• Resolve wall repairs that would be difficult after cabinets are installed.
• Keep the final cabinet drawing available for the installer and trades.

Common mistakes

Problems often begin when each trade works from a different sketch, appliances change without updating the cabinet plan, or service locations are treated as approximate until installation day.

FAQ

Should rough-ins happen before cabinet installation?

Typically, services that will be concealed or constrained by cabinetry are coordinated before final cabinet installation, with final connections completed at the appropriate stage.

Should cabinets be ordered before appliances are selected?

You can plan earlier, but final appliance openings should be verified against the actual selected models before the cabinet order is locked.

Who should perform electrical and plumbing work?

Use appropriately qualified trades and follow applicable Ontario requirements for the work being performed.

What if an existing wall is uneven?

Document it before installation. See the uneven walls and out-of-square corners guide.

Next step

For Burlington, Hamilton and Waterdown projects, treat the final cabinet drawing as the coordination document: cabinets, appliances and rough-ins should all agree before installation starts.
