Installing Tile Flooring: DIY Guide
Tile flooring is more demanding than a backsplash — a larger area means layout mistakes are costlier, and floor tile needs a flatter, more prepared subfloor.
Conditional — Part DIY, Part Pro
Doable for a patient DIYer who's tiled a smaller area (like a backsplash) before, but floor tile demands more precise subfloor prep and layout planning — mistakes are harder to hide over a large floor area.

Step-by-Step
- 1
Prep and level the subfloor
Tile needs a flat surface — use a self-leveling compound for significant unevenness.
- 2
Install cement backer board (if over wood subfloor)
This gives tile a stable, moisture-resistant base.
- 3
Dry-lay your pattern and plan cuts
Find the room's center point and work outward for balanced cuts at the edges.
- 4
Apply thin-set and set tile
Work in small sections, checking level frequently across multiple tiles.
- 5
Let cure, then grout
Typically 24-48 hours before grouting, then seal grout lines if needed.

FAQ
Is tile flooring harder to install than a backsplash?
Yes — floor tile covers a much larger area, so subfloor flatness and layout planning matter far more. A single uneven tile is much more noticeable across a floor than on a small backsplash.
