10 꼭 알아야 할 타일 트림의 종류는?

Exposed tile edges look unfinished and cheap. Trim is what gives your tile project a clean, professional look.

Tile trims are finishing profiles that protect tile edges and corners while enhancing the overall appearance of the installation.

From modern bathrooms to detailed mosaics, the right trim makes all the difference.

What are common tile trim profiles?

You’ve picked the perfect tile. But what happens at the edges? Without the right profile, your installation will look sloppy or worse—start chipping.

The most common tile trim profiles include square edge, round edge (bullnose), L-shaped, Jolly, quarter round, cove, listello, stair nosing, T-molding, and movement joints.

1. Square Edge (Box Trim)

Modern and minimalist, this trim has a sharp 90° edge. It’s perfect for straight wall corners or exposed edges in bathrooms and kitchens.

2. Bullnose

Rounded edge used for soft, finished transitions—especially around tubs, showers, and backsplashes. Great for traditional styles.

3. L-Shape (Straight Edge)

Also called Schlüter-style trims, L-shaped trims protect and finish outer tile edges, typically installed with floor tiles.

4. Jolly Trim

Slim and minimalistic, it creates a crisp visual line at corners or edges. Works well with wall tiles or mosaics.

5. Quarter Round

Used where tile meets a wall or other surface. It gives a soft, rounded finish and hides gaps.

6. Cove Base

Curved inner corner trim for where walls meet floors—especially in bathrooms, hospitals, or commercial kitchens.

7. Listello Trim

Decorative horizontal strip, often used to break up wall tile designs or add contrast.

8. Stair Nosing

Protects step edges while reducing slipping. Essential for tiled staircases.

9. T-Molding

Bridges expansion joints between tiled areas or transitions to other floors.

10. Movement Joint Profile

Used in large areas to absorb expansion/contraction and prevent cracking.

L-Shape	Floors, outer corners	Sleek/minimal
Jolly	Wall tiles, edges	Clean/precise
Quarter Round	Perimeters, baseboards	Rounded finish
Cove Base	Hygienic corners (floor/wall)	Functional curve
Listello	Decorative bands	Contrasting detail
Stair Nosing	Tiled steps	Safe edge
T-몰딩	Floor transitions	원활한
Movement Joint	Large tiled areas	Structural support

How to choose trim for each tile edge?

Wrong trim can ruin the tile look—either it sticks out or doesn’t protect the edge.

To choose the right tile trim, match the tile thickness, consider the edge type (inside, outside, floor, wall), and select a style that complements your design.

This is step one. Trim must match the tile thickness (e.g., 10mm trim for 10mm tile). If it’s too thin, the tile protrudes. Too thick, and it looks sunken.

Determine Edge Location

• Outside corners (wall): Use L-shape, square edge, or Jolly.
• Inside corners (wall/floor): Use cove base or silicone grout.
• Countertops or shelves: Consider bullnose or square edge.
• Where tile ends mid-wall: Jolly or bullnose gives a clean stop.

Consider Design & Finish

Trims come in:

• Matte or polished metal (aluminum, stainless steel)
• PVC/plastic
• Ceramic/porcelain (bullnose)

Pick a finish that blends or contrasts intentionally. For example, brushed aluminum trim pairs beautifully with gray tiles in a modern bathroom.

Edge Situation	Recommended Trim	참고
Wall outer corner	Jolly, square, L-shape	Sleek look
Floor-to-wall joint	Cove base	Easy cleaning
Decorative border	Listello	Visual interest
Step edge	Stair nosing	Safety first

What materials are trims available in?

All trims are not created equal. Some withstand heavy use; others are for looks only.

Tile trims are made from metal, PVC, and ceramic—each offering different strengths, finishes, and cost levels depending on your application.

1. Metal Trims

Most durable and modern-looking. Common types:

• 알루미늄: Lightweight, corrosion-resistant. Ideal for bathrooms and kitchens.
• 스테인리스 스틸: Strong and scratch-resistant. Best for commercial or high-traffic spaces.
• 황동: Premium look, expensive. Often used in luxury bathrooms.

Metal trims work well with square edge, L-shape, and Jolly profiles.

2. PVC (Plastic)

Affordable and flexible, available in many colors. It’s water-resistant and works well in DIY installations. But it scratches more easily and isn’t as sleek.

3. Ceramic/Porcelain Trims

Made from the same material as tiles—great for bullnose trims. Ideal for traditional or classic projects where seamless blending is key.

재료	장점	단점	모범 사용 사례
알루미늄	Sleek, durable, corrosion-free	Can dent under force	Modern interiors, wet areas
스테인리스 스틸	Extremely strong, premium	비싸다	상업 공간
PVC	저렴하고 쉽게 자르기	내구성 저하	Budget installs, DIY
세라믹	Matches tile exactly	Limited profiles	Bullnose edges, traditional

How to install tile trims properly?

Sloppy trim installation makes even perfect tiles look amateur.

To install tile trims correctly, measure precisely, cut cleanly, embed the trim in adhesive, and align it level with the tile edge before tiling over it.

Step 1: Plan and Measure

Mark where the trim will go before you start tiling. Use a level to draw guide lines, especially for vertical trims on corners.

Step 2: Cut the Trim

Use a miter saw, hacksaw, or rotary tool. For clean mitered corners (e.g., outside corners), angle the ends at 45 degrees.

Step 3: Apply Adhesive

Spread tile adhesive (thinset) on the wall/floor area. Press the trim into the adhesive with the edge lip facing out. Make sure it’s flush with your planned tile line.

Step 4: Install Tiles Against Trim

Tile directly up to the trim. Use spacers if necessary to maintain even grout lines. Gently press the tiles and ensure the trim edge is visible but not raised.

Step 5: Grout and Finish

Once tiles are set, apply grout between the tile and trim. Wipe off excess grout with a damp sponge and polish the trim once dry.

전문가 팁

• Don’t overtighten trim into adhesive—leave room for tile.
• Use masking tape to keep trim in place while adhesive sets.
• Always dry-fit everything first.

단계	Tool/Material Needed	Key Note
Measuring	Level, pencil	Plan exact alignment
절단	Saw or grinder	Use protective gloves
Embedding	Thinset mortar	Apply evenly
Tiling	Tile spacers, level	Keep edge flush
마무리	Grout, sponge, cloth	Clean before it dries

결론

Tile trims aren’t just about edges—they’re about excellence. From finish and form to installation and durability, the right trim brings everything together. Whether you’re going sleek and modern or classic and detailed, knowing your trim options will elevate every tile job.
