Zellige Tile Grout: What Spacing and Color to Use
Most tile grout guides are written for porcelain. Uniform edges, consistent thickness, predictable spacing.
Zellige is none of those things.
The edges are hand-cut. The surface undulates. Thickness varies piece to piece. If you approach it like standard tile, you'll either fight the material the whole way through or end up with a result that looks wrong.
Here's what actually works.
Why Zellige Grout Is Different
Zellige is a handmade clay tile from Morocco. Each piece is cut by hand from a larger glazed slab, which means no two tiles are identical. Edges aren't perfectly straight. Corners aren't perfectly square. Thickness can vary by a millimeter or two within the same batch.
That variation is the whole point. It's what gives zellige its characteristic ripple and depth.
But it does mean you have to approach grouting differently than you would with a rectified porcelain or even a standard ceramic.
Grout Spacing for Zellige
The standard recommendation: 1/16" to 1/8" joints.
Most installers and tile setters working with zellige land somewhere in that range. Here's how to think about it:
1/16" (tight) works well when you want the tile surface to read as continuous — almost seamless. The grout line almost disappears and the variation in the tile itself becomes the visual focus. Best for smaller formats like 4x4, and for installations where you want a clean, minimal look.
1/8" (standard) gives you a little more forgiveness during installation. Because zellige edges aren't perfectly straight, a slightly wider joint accommodates the natural variation without forcing tiles into alignment they can't hold. It also makes the installation faster and less stressful for the tile setter.
What to avoid: Going wider than 1/8" on a 4x4 zellige tile starts to look heavy. The grout line competes with the tile rather than framing it. Some installers go as wide as 3/16" on floor applications, but on a backsplash or shower wall, keep it tight.
No spacers, or use tile spacers carefully. Because zellige edges vary, rigid plastic spacers can force gaps that don't suit the tile. Many experienced zellige installers set by eye, using spacers only as a rough guide and adjusting for each tile as they go. If your tile setter hasn't worked with zellige before, brief them on this — it's the single most common mistake on first-time installs.
Grout Color for Zellige
This is where you make a real design decision.
Matching grout (same tone as the tile)
The safest and most common approach. A warm white zellige with an off-white or cream grout reads as cohesive and clean. The tile surface is the star, and the grout stays quiet.
Works well for: kitchen backsplashes, bathroom walls, any installation where you want the tile to carry the room.
Contrasting grout (darker than the tile)
A warm white or cream zellige with a grey or charcoal grout creates a grid effect that emphasizes the geometry of the layout. It's a stronger, more graphic look. Some designers love it. It's also less forgiving — any slight variation in joint width becomes more visible.
Works well for: floor applications, feature walls, bold design statements.
What to avoid: white grout on white zellige. Bright white grout next to the natural warm white of zellige glaze tends to make the tile look dingy by comparison. Go slightly warm — an off-white, linen, or sand tone reads much better.
Grout Type: Sanded vs. Unsanded
For joints under 1/8": unsanded grout. For joints at 1/8" or wider: sanded grout.
Most zellige installations at 1/16"–1/8" fall right on the line. Unsanded is generally the safer call for wall applications — it's easier to work into tight joints and less likely to scratch the glaze during application.
If you're doing a floor with zellige, sanded grout at 1/8" gives you better durability.
One More Thing: Seal the Grout
Zellige glaze is relatively durable, but the grout is not. In wet areas — showers, backsplashes near the stove, bathroom floors — seal the grout after installation and annually after that.
The tile itself doesn't need sealing. The grout does.
It's a five-minute job that prevents years of discoloration.
The Short Version
- Spacing: 1/16" to 1/8", set by eye where possible
- Color: match the tile tone, go warm not bright white
- Contrast: works, but commit to it — half-contrast looks accidental
- Grout type: unsanded for walls, sanded for floors
- Seal: the grout, not the tile, in wet areas
Get those right and zellige installs beautifully. The variation in the tile does the rest.
