How to Calculate Tile Quantity (㎑)

㎑ (square meter) is the tile installation area, and calculating the required number of tiles is essential. Basic formula: Tiles needed = (Room area Γ· Tile area) Γ— 1.1 (10% waste). Example 1: Room 5m Γ— 4m = 20㎑, Tile 30cm Γ— 30cm = 0.09㎑ (0.3Γ—0.3). Tiles needed = (20 Γ· 0.09) Γ— 1.1 = 244 tiles. Example 2: Bathroom 2m Γ— 1.5m = 3㎑, Tile 20cm Γ— 20cm = 0.04㎑. Tiles needed = (3 Γ· 0.04) Γ— 1.1 = 83 tiles. Box ordering: Tiles are sold by the box. 30Γ—30cm tiles usually come 11 tiles per box (1㎑), 20Γ—20cm come 25 per box. For 244 tiles needed β†’ 244Γ·11 = 22.2 boxes β†’ Round up to 23 boxes.

Tile Size Features and Selection Criteria

Large tiles (60Γ—60cm, 80Γ—80cm, 100Γ—100cm): 3~5 tiles per ㎑. Pros: Fast installation, fewer grout lines, space looks larger. Cons: Hard to cut, expensive to replace, leveling critical. Recommended: Living room, entrance, office. Installation cost: $20~30/㎑. Medium tiles (30Γ—30cm, 40Γ—40cm): 6~11 per ㎑. Most commonly used size. Pros: Reasonable price, easy installation, various designs. Recommended: Kitchen, bathroom, balcony. Cost: $15~25/㎑. Small tiles (10Γ—10cm, 15Γ—15cm, 20Γ—20cm): 25~100 per ㎑. Pros: Works for curved/narrow spaces, detailed patterns. Cons: Slow installation, many grout lines, high labor cost. Recommended: Bathroom walls, kitchen backsplash, accent walls. Cost: $25~40/㎑.

Why Include 10% Waste and Budget Planning

Causes of waste: β‘  Cutting damage (30%), β‘‘ Transport/handling breakage (20%), β‘’ Installation cracks (20%), β‘£ Corner/edge trimming (20%), β‘€ Color/pattern defects (10%). Waste rate standards: Straight layout 10%, 45-degree diagonal 15~20%, complex patterns 20~25%. Curved or narrow spaces (bathroom walls) can reach 25~30%. Budget planning: Tile material + installation + supplies. Example: 20㎑ living room, 60Γ—60cm tiles. Tiles needed: (20 Γ· 0.36) Γ— 1.1 = 61 tiles. Tile price: $6 per tile β†’ Total $366. Installation: $25/㎑ β†’ 20㎑ = $500. Supplies (cement, grout, adhesive): $80. Total budget: $946 (about $47/㎑).

04

Tile Pattern Impact on Quantity (Straight, 45Β°)

Straight layout: Most basic installation. Tiles aligned horizontally and vertically. Waste rate 10%. Pros: Fast, cheap, neat grout lines. Cons: Plain. Recommended: General homes, offices. 45-degree diagonal: Tiles rotated 45 degrees in diamond shape. Waste rate 15~20%. More corner cutting increases waste. Example: 20㎑, straight needs 244 tiles vs 45-degree needs 267 tiles (10% more). Pros: Space looks larger, premium feel. Cons: Installation cost 20~30% higher, time 1.5Γ—. Recommended: Living room, hotel lobby. Herringbone pattern: Rectangular tiles in V-shape. Waste rate 20~25%. Pros: Unique design, luxury. Cons: Complex, cost 2Γ—. Recommended: Entrance, boutique.

Tile Installation Cost Calculation and Quote Understanding

Installation cost components: β‘  Labor (tiler + assistant), β‘‘ Materials (tiles + grout + adhesive), β‘’ Removal (existing tile demolition), β‘£ Leveling work (floor leveling), β‘€ Miscellaneous (waste disposal). Tiler labor: Skilled worker $150~250/day, assistant $100~120/day. Per ㎑ cost $15~40/㎑. Large tiles/straight layout cheaper, small/pattern expensive. Material costs: Budget tiles $4~8/tile, mid-range $8~25/tile, premium (imported) $40~80/tile. Grout: $25~40 (20kg), adhesive: $30~50 (20kg). Removal: Existing tile removal $8~12/㎑, concrete breaking $15~25/㎑. Leveling: Cement plastering for uneven floors $12~20/㎑.

Tile Selection Guide (Size, Material, Purpose)

By purpose: Bathroom floor β†’ Non-slip tiles, 20Γ—20cm or 30Γ—30cm, rough matte surface. Bathroom walls β†’ Low absorption porcelain, 15Γ—30cm rectangular, bright colors. Kitchen floor β†’ Acid/oil resistant, 40Γ—40cm large, fewer grout lines for easy cleaning. Kitchen backsplash β†’ Glossy tiles, 10Γ—30cm, oil stain easy to clean. Living room β†’ Luxury marble/wood pattern, 80Γ—80cm or 100Γ—100cm, thin grout. Entrance β†’ Durable porcelain, 60Γ—60cm, dark color (hides dirt). By material: Porcelain β†’ 0.5% absorption, indoor/outdoor, mid-high price. Ceramic β†’ 1~3% absorption, most common, mid price. Earthenware β†’ 10%+ absorption, walls only, cheap. High-end porcelain β†’ Ultra-low absorption, premium, expensive.
