Large-format tile

24×48 porcelain, 48×48 slabs and gauged panels — flat floors, minimal lippage, joints you barely see.

Large-format tile is any tile with a side longer than 15 inches — 12×24, 24×48, 48×48 and gauged porcelain panels — which needs flatter substrates, heavier mortar, back-buttering and controlled offsets to install without lippage.

Big tile is the look of nearly every new build and remodel in the valley right now: fewer grout lines, stone-look porcelain, and rooms that read as one surface. It's also where most bad tile jobs happen, because the rules change at 15 inches. The floor has to be flatter, the mortar has to be a large-and-heavy-tile mortar, every tile gets back-buttered, and a brick pattern with a 50 percent offset will show lippage on any tile that has the slightest bow.

We install large-format tile to those rules: substrate flattened to 1/8 inch in 10 feet, a maximum one-third offset on rectangular tile, leveling clips through the set, and 95 percent mortar coverage checked by pulling tiles as we go. The result is a floor or wall you can run your hand across without finding an edge.

01

What’s included

Every job
  • Flatness survey and grinding or self-leveling of the slab before any tile
  • Large-and-heavy-tile mortar, back-buttered, with coverage checked
  • Layout planned for a maximum one-third offset and balanced cuts
  • Leveling clips and wedges through the entire installation
  • Gauged porcelain panels handled with frame and suction systems, cut on site
  • Narrow joints with matching grout, movement joints where the room needs them

How it works

Three steps
  1. 01

    Survey the floor or wall

    A straightedge tells us how far from flat the slab is and how much prep the job needs. The estimate separates prep from tile so you see where the money goes.

  2. 02

    Flatten and prime

    Grinding for high spots, self-leveling underlayment for low ones, primer and membrane. Big tile is only as good as what's under it.

  3. 03

    Set with the system

    Back-buttered tile, leveling clips, a laser line across the room. Clips come off, joints are grouted, and the surface is one plane.

Large-format tile by town

Where we do this
  • La Quinta

    New-construction homes in La Quinta's gated communities come with 24×48 porcelain throughout; we match patterns across rooms and fix the lippage other crews left.

  • Indian Wells

    Gauged porcelain panels on Indian Wells feature walls and fireplaces — one slab, no joints, templated to the inch.

  • Palm Springs

    Palm Springs modern remodels favor 48×48 and terrazzo-look porcelain on slabs that need serious flattening first.

Fair questions

Large-format tile FAQ

Why does large-format tile need a flatter floor?

A 48-inch tile bridges dips and humps instead of following them, so every irregularity shows up as lippage at the edges. The industry standard for tile over 15 inches is 1/8 inch in 10 feet; small tile only needs 1/4 inch.

What offset do you use on rectangular tile?

No more than a third. Long porcelain tiles have a slight bow from firing; at a 50 percent offset the high center of one tile meets the low end of the next and you get lippage no clip can fix. One-third keeps the edges aligned.

Can you install porcelain slabs or gauged panels?

Yes — 5×10-foot gauged porcelain panels for shower walls, fireplace surrounds and feature walls. They need two people, a transport frame, suction cups and careful cutting, and the walls behind them need to be dead flat.
