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. 1

    Prep and level the subfloor

    Tile needs a flat surface — use a self-leveling compound for significant unevenness.

  2. 2

    Install cement backer board (if over wood subfloor)

    This gives tile a stable, moisture-resistant base.

  3. 3

    Dry-lay your pattern and plan cuts

    Find the room's center point and work outward for balanced cuts at the edges.

  4. 4

    Apply thin-set and set tile

    Work in small sections, checking level frequently across multiple tiles.

  5. 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.
