Quick answer: Handmade zellige often demands more layout decisions than a rectified factory tile. Slight variation in edges, thickness and glaze affects joint spacing, alignment and the finished reflection. Installation also depends on what the tile is being bonded to and whether the area must resist water. A sample mock-up and qualified installer are more useful than promising one fixed grout gap for every handmade tile.

Should I dry-lay handmade zellige before installation?
Yes, a trial layout is often useful. Spread a representative batch on a protected surface, blend shades from several boxes and compare real dimensions. Decide where cuts and transitions fall before fixing tiles. On an exposed feature wall, a deliberate sample area lets the owner agree on the natural variation and joint appearance. Follow the actual supplier’s handling instructions.
What grout spacing is right for handmade zellige?
There is no universal grout width. Variations in dimensions and geometry may mean the installer needs adjustments to maintain the desired visual line while allowing complete joint fill. Follow the project design and manufacturer recommendations. Do not force a zero-gap aesthetic in a wet environment if the assembly cannot be built or maintained reliably.
What mortar or adhesive should I use?
Select a setting material that is compatible with the substrate, tile body, exposure, load and manufacturer specification. The installer should check the mortar manufacturer’s coverage and curing instructions. An unsupported internet rule like ‘all zellige needs this one adhesive’ can be unsafe. Material selection should account for local standards and conditions rather than simply the appearance of the tile.
Do I need a waterproof membrane in a shower?
Waterproofing is part of the complete shower assembly. TCNA notes that grout joints are not waterproof and that the assembly must protect adjacent materials. Specific membranes, backer boards, drains and junction details require compatibility, and local code may limit permitted approaches. Have the architect and installer select an approved system instead of treating the tile itself as the waterproof layer.
How do I handle chipped or uneven edges?
First distinguish intentional hand-finishing within approved sample range from damage that undermines function or appearance. Define acceptance criteria during ordering and inspect delivered material before installation. Trim and exposed edge details should be designed in advance, because dimensional variation may leave unexpected gaps near corners and outlets.
When should the grout and tile be cleaned?
Follow the adhesive, grout and tile manufacturers’ curing and cleaning instructions. TCNA advises not to start grout cleanup too early or wash excessive water across joints. Acidic cleaners and abrasive tools can damage sensitive surfaces or components. Test any proposed cleaner on a spare sample before it contacts the entire installation.
Who should install zellige in a U.S. project?
Choose an installer experienced with irregular handmade tile and with the assembly required by your exposure and jurisdiction. For wet rooms, showers and commercial floors, insist on documented systems and design professional oversight where required. Keep photographs, samples and decisions in the project submittal record so the approved aesthetic and technical expectations stay aligned.
