Parametric Tile Floor in Grasshopper – Step-by-Step Tutorial

Looking to create a tile floor design in Grasshopper? In this tutorial, I’ll show you how to build a parametric floor layout with a border and customizable pattern inside. Using sliders in Rhino + Grasshopper, you can generate endless variations for tile layouts, grout thickness, and decorative patterns.

Step 1: Define the Floor Area

Start with a parametric rectangle in Grasshopper. Add sliders to control width and height so you can quickly resize the tile floor for any space.

Step 2: Add the Border Band

Offset the rectangle inward to create a border. Using a loft with mitered corners gives clean edges, perfect for framing the inside pattern.

Step 3: Subdivide the Tiles

Use the Contour component to split the floor evenly in both X and Y directions. Sliders let you change tile size instantly.

Step 4: Create a Pattern

Convert the inside area to a surface, subdivide it, and place circles at grid intersections. By adjusting radius and spacing, you can generate unique tile patterns.

Step 5: Add Grout and Colors

Offset curves slightly to define grout lines, then apply Custom Preview with different color swatches for tiles and grout. This helps visualize real-world results.

Step 6: Visualize with AI Rendering

Export the tile design and upload it to Rerender AI (or another render tool). This lets you see the pattern inside realistic environments, like a modern restaurant or retail store.

Why Use Grasshopper for Tile Floors?
