The Most Expensive Tile in the Room Still Has to End Somewhere

A jump in the share of Bert & May's glazed-tile orders that included trim points to a larger change: the place where tile stops is becoming part of the composition.

A tiled wall tells you what it wants to be right up until it reaches a corner. Then many expensive rooms panic.

On September 14, the Financial Times reported a striking shift at Bert & May. In 2025, trims appeared in 6 percent of the company's glazed-tile orders. During the three preceding months, that share was 42 percent.

The number needs its full label. It comes from one brand, covers glazed-tile orders and compares a full calendar year with a recent three-month window. No order count or audited dataset was published. It is not proof that 42 percent of the tile market suddenly discovered quarter-round. It is still a useful signal because several brands are expanding the pieces, guidance and vocabulary used to finish tile.

Trim is returning not as Victorian nostalgia, but because designers are promoting the edge from cleanup detail to composition.

The number is dramatic and specific

Moving from 6 percent to 42 percent means trim appeared in seven times the share of Bert & May's glazed-tile orders. The same FT article says Balineum reported an almost 80 percent rise in trim sales over the preceding year. Both figures are company-reported.

The safe conclusion is not that tile-trim demand rose 600 percent across the industry. The safe conclusion is that two design-led British brands are seeing materially more interest in finishing pieces, while current ranges from Bert & May, Balineum and Fired Earth make that interest visible in product form.

Signals become interesting when behavior and supply move together. Here, a larger share of one company's glazed-tile orders includes trim while brands are giving designers more ways to use it.

Victorian trim was architectural punctuation

Tile historian Hans van Lemmen told the FT that Victorian trims were used to edge, delineate and accentuate tiled surfaces. Nineteenth-century systems included skirtings, dado rails, corner beading and architraves. These pieces did not merely conceal a raw edge. They gave a tiled plane a beginning, middle and end.

That helps explain why the revival feels larger than nostalgia. A moulded edge catches light differently from a flat field tile. A dado changes the scale of a wall. A corner piece lets ceramic turn through space rather than stop apologetically before it.

The Victorian Society offers one useful warning: avoid fake "Victoriana." Historical detail works best when its architectural logic survives, not when every period motif arrives at once.

Trim has left the perimeter

The newest applications are not confined to the top of a backsplash. The FT featured dark green half-round trims defining mirrors, tiled wall panels and window casings in a Dallas bathroom by Avery Cox Design. Harford House used a burgundy pencil trim to manage a transition between half-height tile and a full-height shower.

At Enrica Rocca in Notting Hill, Studio George placed knobbly red trim pieces within the backsplash itself. The trim became a stripe, not an ending. That move is important because it turns a technical component into a compositional one.

Balineum's current 36-page guide similarly covers external corners, dados, pony walls, shelves, openings, basin surrounds and junctions between three planes. The edge is no longer one line. It is a system of moments where surfaces meet.

Expensive tile can still look unfinished

A beautiful surface cannot rescue an unresolved transition. Exposed bodies, abrupt metal strips, mismatched profiles and improvised corners can make costly material look like it arrived before the drawing did.

Trim also changes practical decisions. The installer needs to know its dimensions, glaze coverage, radius and relationship to the field tile. Wet areas, external corners and niches create different conditions. Some collections offer coordinated profiles. Others require stone fabrication, mitred edges, metal profiles or another deliberate solution.

The correct choice depends on the material and installation. The universal advice is simpler: make the decision before ordering, not when the installer reaches the corner.

Treat the edge like millwork

Draw every place where tile stops, turns or changes height. Mark doorways, windows, niches, shelves, half-walls, shower returns, countertop junctions and transitions into another material. Then decide which edges should disappear and which should become visible.

A quiet edge can use a matching profile. A stronger composition might use contrast, relief or a repeated liner. The profile should relate to the room's other lines, including cabinetry, stone slabs, mouldings and plumbing heights.

Millwork is rarely specified as "wood, somehow finished at the ends." Tile deserves the same respect. The edge is not the final accessory. It is part of the original drawing.

Tile does not become architecture in the middle of the wall. It happens at the edge.

Bullnose: A tile with one rounded, finished edge.
Pencil or liner: A narrow trim used as a border or transition.
Dado: A horizontal moulded element that caps or divides a wall treatment.
Quarter-round: A convex profile used at corners or transitions.
Reveal: A deliberate recessed or exposed junction between surfaces.

Key Takeaway

The trim revival is not permission to add moulding everywhere. It is a reminder to design the termination. Decide how the tiled plane meets corners, openings and other materials while the room is still on paper.

HAUS Translation

Add an "edge answer" to every specification: matching trim, fabricated stone, mitre, metal profile or another verified method.
Photograph collections at corners, niches and transitions so customers can understand the architecture, not only the face of one tile.
Audit which HAUS collections have compatible finishing pieces or documented alternatives. Do not imply that a coordinated trim exists until dimensions and availability are verified.

Finish the edge before it becomes a problem

Before finalizing tile quantity, draw every edge. Your installer will thank you. The room will look like it knew where it was going. Button: Read the Tile Planning Guide Link status: Requires a verified existing guide or a future content destination.
