Bathroom Tile Selection Guide

Bathroom tile decisions get made at Tile Roanoke, Ferguson, Floor & Decor in Christiansburg, or online, and the visit or online session can be overwhelming. Ten thousand SKUs, dozens of material types, price ranges from $2 to $40 per square foot. This guide provides the framework to make those choices confidently.

Material types

Porcelain

Porcelain is the workhorse tile, dense, water-resistant, durable, and available in a huge range of styles that mimic natural stone, concrete, wood, and pure abstract designs. Almost every Roanoke bathroom project uses porcelain as the primary material.

• Best for: Shower walls, shower floors, bathroom floors, everything.
• Price range: $3-$12 per square foot for the tile itself.
• Durability: Excellent. Water absorption under 0.5 percent.
• Maintenance: Grout maintenance only. The tile itself needs no sealing.

Ceramic

Ceramic tile is less dense than porcelain and typically has a glazed surface. Cheaper but less durable, the glaze can chip at edges. Fine for walls, adequate for floors in low-traffic bathrooms, not recommended for shower floors.

• Best for: Powder room floors, hall bath walls, tighter-budget projects.
• Price range: $2-$6 per square foot.
• Durability: Fair to good. Chip-prone at edges.
• Maintenance: Glaze wears; not for high-traffic showers.

Natural stone (marble, travertine, granite, slate)

Natural stone is beautiful and premium but requires ongoing sealing (every 1-3 years) and is more sensitive to acidic cleaners (which etch marble in particular). Best for primary suites where the maintenance is acceptable, not for hall baths.

• Best for: Primary suite floors and walls, statement showers, feature walls.
• Price range: $8-$30 per square foot depending on stone type and source.
• Durability: Depends on stone type. Marble is soft; granite is very hard; travertine is porous.
• Maintenance: Sealing every 1-3 years. pH-neutral cleaners only.

Mosaic

Mosaic is a format, not a material, small tiles (1-inch or 2-inch) mounted on mesh sheets. Can be porcelain, ceramic, natural stone, or glass. Used as accents (single wall, niche interior, floor pattern) rather than full room coverage.

• Best for: Shower niche interiors, accent walls, decorative floor patterns.
• Price range: $8-$40 per square foot depending on material.
• Installation labor: Higher than large-format tile, more grout lines, more time.
• Slip resistance: Good for shower floors due to grout lines providing traction.

Glass tile

Glass is beautiful, reflects light, and adds visual interest. Best used as accent or feature, full glass tile walls are expensive and challenging to install cleanly. Common in niche interiors and small accent bands.

• Best for: Niche interiors, small accent bands, backsplashes.
• Price range: $12-$40 per square foot.
• Installation: Requires white thinset (colored thinset shows through), careful edge finishing.

Format decisions

Large-format (12x24 and larger)

Large-format tile is the current default for shower walls and bathroom floors. Fewer grout lines make the room read larger and more contemporary. Slightly more difficult to install (requires medium-bed thinset and careful substrate flatness) but the aesthetic is worth it.

For shower floors, large-format requires a linear drain (single-plane slope) rather than a point drain (four-corner slope). Point drains force small tile or mosaic on the floor.

Subway tile (3x6, 4x8, or larger)

Classic, timeless, works in almost any Roanoke home style. 3x6 is the traditional dimension; larger subway variants (4x12, 4x16) are more contemporary. Herringbone or vertical stacked pattern add interest.

Hex and small format (1-inch, 2-inch, 4-inch)

Traditional in 1920s-1940s Roanoke bungalows. Original hex-tile floors in Old Southwest homes are often worth preserving. Modern hex options (marble, colored porcelain) are available for new installations.

Slip resistance (DCOF)

Dynamic Coefficient of Friction (DCOF) measures wet slip resistance. TCNA guidelines require:

• Floors intended to be walked on when wet: DCOF ≥ 0.42
• Aging-in-place bathrooms: DCOF ≥ 0.60 recommended

Every tile SKU has a DCOF rating on the technical spec sheet. Polished porcelain typically rates 0.30-0.40 (below threshold, not for floors). Matte and textured porcelain typically rates 0.42-0.75 (safe for floors). Natural stone varies widely.

DCOF is worth checking on every floor tile during selection.

Where to buy tile in Roanoke

Local Roanoke tile suppliers:

• Tile Roanoke: Independent showroom in Roanoke. Good porcelain and natural stone selection, knowledgeable staff.
• Ferguson (multiple Roanoke Valley locations): Full-service, tile plus fixtures, cabinets, and countertops. Strong on plumbing fixtures.
• Floor & Decor (Christiansburg): Big-box selection with lower prices. Good for budget-conscious projects; less selection of higher-end natural stone.
• Lowes and Home Depot: Basic selection, good for straightforward projects at builder-grade level.

Online: Wayfair, Overstock, Build.com, and direct-from-manufacturer sites (Daltile, Marazzi) all ship tile. Ordering online can save 15-30 percent but requires accurate quantity estimation (add 10-15 percent for cuts and waste) and no ability to see the tile in person before purchase.

Common mistakes

• Buying too little tile. Always add 10-15 percent to the calculated square footage for cuts, waste, and future repairs. Running out mid-install and finding the same batch out of stock is a real problem, dye lots vary and matching becomes difficult.
• Using polished tile on floors. Below DCOF threshold. Slip hazard, especially in family bathrooms.
• Choosing based on photos alone. Tile looks different in your bathroom's lighting than in the showroom. Get sample pieces (most suppliers loan or sell $5-10 samples) and view in the actual space.
• Mixing tile from different sources for a single install. Tolerance variations from different manufacturers cause installation problems.
• Ignoring the DCOF spec. Especially in aging-in-place projects.

Get help with the selection

The material and format decisions get walked through during the selection phase of any well-run project, and there should be no separate design fee for a standard bathroom scope.
