How long does a tile bathroom floor take?

A standard primary bath (75-100 sqft) runs 3-4 working days: day 1 prep, day 2-3 set tile, day 4 grout and seal. You can walk on it 24 hours after grouting.

Can I install tile over existing tile?

Sometimes. If the existing tile is sound, level, and not hollow, yes — with an anti-fracture membrane. We usually recommend removing old tile because LI homes settle and hidden subfloor issues are common.

Cement grout cracks in wet areas within 5-7 years. Epoxy grout lasts 20-30 years. We recommend epoxy for all kitchens, bathrooms, mudrooms, and entryways.

Porcelain and ceramic: pH-neutral cleaner (not vinegar) once a week. Natural stone: stone-specific sealer every 1-2 years, pH-neutral cleaner weekly. Never use ammonia or bleach on stone.

Overview

Why Long Island chooses us for tile.

Tile is permanent. Done right, it will outlast the house. Done wrong, it cracks at the grout lines in five years. We cut in-house with a wet saw, we level with self-leveling compound when needed, and we grout with epoxy on wet areas because regular cement grout fails predictably at year 5-7.

What You Get

The specifics.

Porcelain & Ceramic

Large-format porcelain (12x24, 24x24, 24x48) is the current standard for bathrooms and kitchens. Marble-look, wood-look, and concrete-look patterns. Inkjet-printed surfaces are indistinguishable from stone.

Natural Stone

Travertine, slate, marble, limestone for high-end installations. Requires sealing every 1-2 years but looks like nothing else. We only install natural stone with an anti-fracture membrane on LI's seasonal substrate movement.

Epoxy Grout on Wet Areas

Standard cement grout fails in wet environments — bathrooms, mudrooms, kitchen sink zones. Epoxy grout is 10x more expensive and 10x longer-lasting. We use Mapei Flexcolor or Laticrete Spectralock.

Heated Floor Compatible

We install electric radiant floor heat under porcelain and stone. Schluter Ditra-Heat or SunTouch WarmWire. Kitchens and bathrooms feel transformed with heated tile.

Our Process

How we do it.

1
Level the subfloor
Tile cracks when the subfloor flexes or isn't level. We install cement backer board (1/4" HardieBacker) on wood subfloors, and use self-leveling compound on concrete where needed.
2
Anti-fracture membrane
Schluter Ditra or Kerdi on any installation 10+ years expected. Prevents substrate movement cracks. A LI Flooring standard, not an upcharge.
3
Dry-lay & cut pattern
We lay out the entire floor dry before mortaring. Centering, pattern match, cut pieces positioned where they look best. This step is skipped by budget installers.
4
Thinset mortar & set tile
Notched trowel to the substrate, back-butter the tile on large format. Level each tile as it sets. Day 1 = cut and prep + dry lay. Day 2-3 = set. Day 4 = grout.
5
Grout with epoxy (wet areas) or cement (dry)
Spacers pulled, joints cleaned, grout floated in, excess wiped off. Epoxy grout on any wet area. Sealer on natural stone.
