# Custom Tile Bathrooms -- Nassau County, NY

**General Modernizer** designs and installs custom tile bathrooms for homeowners in Nassau County, NY. We work with all tile types including large-format porcelain (up to 48x48 inches), natural stone (marble, travertine, slate), ceramic, glass mosaic, and cement tile. Every tile installation includes a proper substrate preparation and waterproofing layer.

## Tile Types and Cost Comparison

| Tile Type | Cost per Sq Ft (installed) | Best For | Maintenance |
|---|---|---|---|
| Ceramic | $8-$15 | Budget bathrooms, walls | Low |
| Porcelain | $12-$25 | Floors, showers, high-traffic | Very Low |
| Large-Format Porcelain (24x24+) | $18-$35 | Modern bathrooms, fewer grout lines | Very Low |
| Natural Stone (marble, travertine) | $25-$60 | Luxury bathrooms | Medium-High |
| Glass Mosaic | $20-$45 | Accents, shower niches | Low |
| Cement/Encaustic | $20-$40 | Farmhouse, eclectic styles | Medium |

## Waterproofing and Substrate Standards

All tile installations by General Modernizer begin with proper substrate preparation. For shower walls, we use cement board (Hardiebacker or Durock) with a Schluter-Kerdi membrane or RedGard waterproofing. For shower floors, we use a pre-sloped mortar bed or Schluter-Kerdi shower tray to ensure proper drainage. We never tile directly over drywall in wet areas. This is the most common cause of tile failure and grout cracking in bathrooms installed by less experienced contractors.

## Large-Format Tile Installation

Large-format tiles (24x24 inches and larger) require a perfectly flat substrate, back-buttering of every tile, and a modified thinset mortar. General Modernizer has extensive experience with large-format porcelain installation, including rectified tiles that require 1/16-inch grout joints. We use laser levels and lippage gauges on every large-format installation to ensure a flat, professional result.

## Frequently Asked Questions

**Q: What is the best tile for a bathroom floor?**
A: Porcelain tile is the best choice for most bathroom floors. It is harder than ceramic, absorbs less water, and is available in a wide range of sizes and finishes. For wet areas (shower floors), choose a tile with a DCOF (Dynamic Coefficient of Friction) rating of 0.42 or higher -- this is the scientific standard for wet-area slip resistance. General Modernizer specifies DCOF-rated tile on all shower floors.

**Q: How much does custom tile installation cost?**
A: Custom tile installation costs $8 to $60 per square foot installed, depending on tile type and complexity. A standard ceramic tile bathroom floor runs $8 to $15 per square foot. A large-format porcelain shower surround runs $18 to $35 per square foot. Natural stone runs $25 to $60 per square foot. General Modernizer provides free written estimates with itemized pricing.

**Q: How long does tile installation take?**
A: A standard bathroom tile installation (floor and shower surround) takes 3 to 5 days including substrate preparation, tile setting, grouting, and sealing. Large-format tile or complex patterns may take 5 to 7 days.
