Kitchen Countertops in Ontario: What They Cost, What They Are Made Of, and Where the Seam Goes

Installed prices, honest material comparisons, the lines a fabricator adds after the per-square-foot number, and a calculator that prices all of it.

A countertop is the one part of a kitchen where the advertised price per square foot means the least. The slab is half the invoice. These pages are about the other half, and about choosing a material you will not regret the first time a hot pan lands on it.

If you are doing cabinets too

The cabinet calculator prices cabinets and countertop together, and the renovation calculator prices the whole job.

Three things to know before you call a fabricator

  1. Template after the cabinets are fixed and level, never before. The top is cut to what is there on template day. If the cabinets move after, the top does not fit.
  2. Ask where the seam goes, on the drawing, before the saw starts. A quartz slab is about 10 feet long. A 14-foot run has a seam. Good shops put it where you will not look.
  3. Compare installed quotes on one written scope, not per-square-foot prices. One includes the sink cutout, edge and install; the other is the slab. The calculator writes the scope.

Choosing between them in one line each

Quartz: consistent, no maintenance, trivets forever. Granite: real stone, takes heat, ten minutes of sealing a year, the value stone at level 1. Quartzite: the marble look that behaves like granite, for $35 a foot more. Porcelain: heat-proof and stain-proof, for a fabricator who has done twenty of them. Laminate: the right answer for a rental, a cottage, or a five-year plan.

Thirty seconds and no email: your counter runs in, an installed number out, with the cutouts and the seams.

Before you sign anything

Three installed quotes on one scope. The seam on the drawing. A sample at home under your own lights. A plumber booked for the day after the install. Do those four and the countertop is the easy part of the kitchen.
