Bosch GTL3 65-Foot Wall and Floor Tile Layout and Squaring Laser Level Kit

The Bosch GTL3 65-Foot Wall and Floor Tile Layout and Squaring Laser Level projects high-visibility 0-degree, 45-degree, and 90-degree reference lines from a single setup to streamline floor tiling, wall backsplashes, and room squaring tasks. Engineered with elevated beam optics that clear mortar beds and surface bumps, this compact alignment tool eliminates the need for messy chalk lines. Featuring an integrated magnetic mounting base, a steel positioning plate, and an IP54 dust-resistant housing powered by 4 AA batteries, this professional tile laser provides flooring contractors with instant, error-free angular layouts.

Best Used For:

  • Floor Tile & Backsplash Layouts: Aligning square and diagonal tile grids across floors and kitchen walls with 0°, 45°, and 90° reference lines.
  • Room Squaring & Partition Framing: Establishing true 90-degree right angles from a single setup point during interior framing.
  • Mortar-Clear Obstacle Projection: Projecting elevated laser lines over wet thinset mortar beds and uneven subfloor surfaces seamlessly.

Key Performance & Safety Features

  • 0°, 45°, and 90° Beam Projection: Projects concurrent squaring lines plus an optional diagonal 45-degree layout beam instantly.
  • Elevated Laser Optic Design: Beams are raised above the laser base to travel past mortar ridges and floor debris without obstruction.
