The answer depends on which Ella wall product you choose. Only the grout-free tiles are sold by the box, while the panel systems are sold as kits with a fixed number of pieces. The large gray marble panel tile comes in packs of 8 that cover about 21 square feet, the interlocking click tile is boxed to cover about 16 square feet per box, and the panel kits run from 3 pieces up to 12 pieces. The measuring method and what to have ready when you ask about an order are in How to Get Pricing and Order Ella Grout-Free Shower Wall Tiles: Measuring Your Walls and Estimating Boxes.
Tiles That Are Sold by the Box
Three Ella wall tiles are bought by the box or pack. Each one is labeled a little differently, so it helps to know which figure is published for which tile.
- Gray marble panel tile. This is the one tile with a printed piece count. Each tile measures 25.6 inches long by 14.8 inches wide and is about 0.2 inch thick, and the tiles come in packs of 8 that cover about 21 square feet of wall.
- Interlocking click tile. This tile is sold by the box and comes in five colors. Each box covers about 16 square feet of wall. The published material gives the coverage per box, not a tile count, so plan with the coverage figure.
- 12 inch by 24 inch grout-free tile, including the Carrara White pattern. This tile is bought by the box, in whatever number of boxes your walls need. A piece count per box is not listed in this knowledge base, so ask your Ella dealer or the team at (800) 480-6850 to confirm the count and the coverage printed for that tile before you settle on a number.
Coverage is the figure that matters most for planning. The box count changes with the tile size, so two tiles that look alike on a screen can need a different number of boxes for the same wall. Always confirm the coverage printed for the specific tile you choose, and work from that figure instead of a piece count.
Piece Counts for Every Ella Wall Product
People searching for tiles per box are often comparing a boxed tile with a panel kit. The table puts the published counts side by side. Where a figure is not published, the cell says so.
| Wall product | Pieces per box, pack or kit | Published size or coverage | What it means for you |
|---|---|---|---|
| Gray marble panel tile | Pack of 8 | About 21 square feet per pack. Each tile is 25.6 by 14.8 inches. | Buy as many packs as your walls need |
| Interlocking click tile | Not listed | About 16 square feet per box | Plan by coverage. Five colors to choose from. |
| 12 by 24 inch grout-free tile (Carrara White) | Not listed | Not listed | Sold by the box. Confirm the count and coverage before ordering. |
| SMC subway 12-piece kit | 12 panels: four 60 by 24 inch and eight 36 by 24 inch | 36 by 60 by 96 inches | A full-height alcove in one kit |
| SMC subway 9-piece kit | 9 panels | 72 inches high | A lower shower |
| SMC subway 6-piece kit | 6 panels | 48 inches high | Walk-in tub surrounds that do not need floor-to-ceiling coverage |
| Acrylic 3-panel shower wall kit | 3 panels: one 60 inch back and two 40 inch sides | 40 by 60 by 98 or 40 by 60 by 105 inches | Large seamless panels that can be cut to fit |
| Acrylic 6-piece kit in Carrara White | 6 pieces | 36 by 60 by 92 inches | Marble look with storage shelves on the left side |
Boxed tiles and panel kits scale differently. Tiles scale to any wall. A taller ceiling, a third wall or a shower you already have simply means more boxes. Kits are fixed sets built around an alcove footprint, so with a kit you check the footprint and the height, not the number of pieces. The SMC kits and the 6-piece acrylic kit are sized for a 36 by 60 inch alcove, and the acrylic 3-panel kit is sized for a 40 by 60 inch footprint. If you are weighing a subway kit against Carrara White tile, remember that the kit is a set of panels while the tile is bought in whatever number of boxes your walls need. The printed dimensions for every system are collected in Wall Kit Sizes at a Glance.
What Is Inside Each Panel Kit
The SMC subway kits are glossy white panels with a subway tile pattern, an integrated flange on each panel and a tongue-and-groove interlock. The 12-piece kit contains four 60 by 24 inch back panels and eight 36 by 24 inch side panels, and the panels go up bottom row first. SMC kits ship in a wooden frame with bubble wrap, foam and sealed plastic. The SMC kits are a different product from the grout-free tiles, so be specific about which one you are asking about.
The acrylic 3-panel kit is one back panel 60 inches wide and two side panels 40 inches wide, in your choice of a 98 or 105 inch height. The three flat panels roll and ship in a 24 by 24 by 61 inch box at 81 pounds. A shorter 40 by 48 by 60 inch version of the same 3-panel system is offered as a walk-in tub wall surround. The 6-piece acrylic kit arrives as six pieces in a Carrara White marble look, 1/8 inch thick, with storage shelves on the left side. Its details are in the guide to the acrylic 6-piece wall panel kit.
Cultured marble is the fourth family. The video on this page shows the cultured marble travertine shower walls, which come as multi-piece surrounds of eight, six or four panels. It explains that the panels can be carried and installed by one person, and that they can be glued over drywall, plaster, painted walls, Durock or even existing tiles. The edges are factory finished for seamless joining and can still be trimmed and cut for a custom fit. All four families are compared in Wall Panels and Surrounds for Walk-In Tubs.
Turning Coverage per Box into a Box Count
Once you know the coverage per box for your tile, the number of boxes is simple arithmetic.
- Measure the height and width of every wall surface you plan to cover, in inches.
- Multiply height by width for each wall and add the results together.
- Divide the total by 144 to get square feet.
- Divide the total square feet by the coverage per box for your tile, then round up to whole boxes.
- Note any windows, niches or partial walls that change the count, and mention them when you ask about your order.
About four boxes is a common starting point for a standard tub alcove. It is a starting point, not a rule. Ceiling height, whether the tile runs all the way to the ceiling, and whether you are covering one wall or three all change the total, so measure your own walls.
What to Confirm Before You Order
- The tile name and color, for example the 12 by 24 grout-free tile in Carrara White, or the click tile color you prefer.
- The coverage printed for that tile, and the piece count per box if you need it for your layout.
- Your wall measurements or the box count you calculated.
- Whether the walls surround an Ella walk-in tub, an Ella shower base, or a shower you already have. The tongue-and-groove grout-free tiles can be used around a walk-in tub as well as in a shower.
- How the exposed edges will be finished. Molding is not included with the acrylic panels, and the options are explained in How Shower Wall Edges Are Finished.
Availability of each wall line changes over time. Your Ella dealer or the team at (800) 480-6850 can confirm what is current and the box or kit contents for the product you pick. When panels are ordered together with a tub, they ship with the tub order.
