Kitchen Backsplash Tile Install - What I Learned DIYing My First Tile Project

Did my first tile project ever on our kitchen backsplash last month - 22 sq ft of 3x12 subway tile in our North York kitchen. Sharing the process, mistakes, and lessons for other first-timers.

Why DIY?

Quotes ranged from $750-$1,100 for labour on a job that seemed manageable. Tile: $180 for the Daltile subway (bought extra, used about 19 sq ft). Decided to try it.

Tools Acquired

  • Rented wet tile saw from Home Depot: $55/day
  • Notched trowel (3/16" V-notch): $12
  • Grout float: $14
  • Grout sponge + bucket: $8
  • Level, tape measure: had these
  • Tile spacers (1/16"): $6

Total tool spend: $95 (wet saw rental + tools)

The Process

Day 1: Remove old backsplash (it was just painted drywall - confirmed no moisture damage), install cement board behind sink area, let dry overnight. 3 hours.

Day 2: Lay out tile dry, mark centre line, mix polymer-modified thinset, spread thinset with notched trowel in small sections, set tile. Got through 80% of the field tile. 5 hours.

Day 3: Cut and install perimeter and outlet tiles (all the tricky cuts). Hardest part - a few wasted tiles learning the wet saw. 4 hours.

Day 4: Apply Mapei Ultracolor Plus grout, clean, remove spacers. 3 hours.

Mistakes Made

Thinset coverage: first section I applied thinset to the wall but not the back of the tiles. Get 95%+ coverage on the back too for proper adhesion - learned this after reading it was the correct method.

Grout timing: applied grout a bit early (24 hours after thinset instead of 48). It was fine but set faster than expected.

Cutting: wasted 6 tiles figuring out the wet saw. Always budget 15% extra tiles.

Result

Looks great. Could not be happier. Total cost: $180 (tile) + $95 (tools) + $45 (thinset/grout/supplies) = $320 vs $750-$1,100 contractor quote. Saved $430-$780.

Is it perfect? No - look closely and some grout lines are slightly uneven. Does it look great in the kitchen? Yes.
