A Calgary installer's guide to grout colour, light vs dark, hard water staining, room-by-room picks, and how to test before you commit.
Homeowners spend weeks choosing tile, then pick a grout colour in two minutes. That imbalance is responsible for more regrets than almost anything else we deal with on the job. Grout covers anywhere from 5 to 20 percent of your tiled surface. That's not a detail, it's part of the design.
What grout colour actually does to a tile
Contrasting grout emphasizes each individual tile and makes the pattern visible. Matching grout creates a seamless surface where the tile reads as one continuous plane. Neither is right or wrong, the question is what you're trying to achieve in the room.
Light vs dark grout, the real trade-offs
Light grout shows dirt faster, that's a maintenance reality. Dark grout hides everyday grime but has its own issue in Calgary, the city has hard water and mineral deposits show as white residue on dark grout, especially around shower heads. Medium grey is the most popular grout colour in Calgary tile installation for a reason, it splits the difference on both problems.
How to test before you commit
Get grout samples, not just tile samples. Apply the sample to a tile and let it dry completely. Grout looks darker wet than dry, and the dry colour is what you're living with. Test under the lighting in your actual space, showroom lighting is designed to make everything look good.

Room-by-room guidance
Kitchen backsplash, contrast works well, particularly with white subway tile. Bathroom floor, go medium to dark, light grout is a cleaning commitment most people aren't ready for. Shower walls, matching grout is the safer call. Large-format floors, colour matters less because there's so little grout.
The Calgary hard water factor
A penetrating silicone sealer applied after installation and reapplied every one to two years is the most practical protection. For shower grout specifically, epoxy grout is worth considering, it doesn't require sealing, resists moisture completely, and doesn't stain. Costs more and is harder to install, but in a Calgary shower used daily, the trade-off is usually worth it.
