How much does tile flooring cost?

Installed tile runs about $7 to $20 per square foot, or roughly $1,800 to $6,000 for a typical room, with labor often the bigger share. DIY materials are about $3 to $8 per square foot, so the savings come from doing the labor yourself.

Can I install tile flooring myself?

Yes, but it is more involved than a floating floor. The skills are prepping a stiff substrate, combing thinset evenly, keeping tiles level and spaced, and grouting cleanly. Start with a small, square room and rent a wet saw.

Do I need backer board under floor tile?

Over wood subfloors, yes, you need cement backer board or an uncoupling membrane so the tile has a stable, crack-resistant base. Tiling directly over plywood almost always leads to cracked grout and loose tile.

Ceramic or porcelain floor tile?

Porcelain is denser, harder, and more water- and wear-resistant, which makes it the better choice for floors and wet areas. Ceramic is cheaper and fine for lighter-traffic floors. For entryways and baths, most pros pick porcelain.

How long does a tile floor take to install?

A typical room takes a weekend or two for a DIYer: prep and backer board one day, setting tile another, then grouting after the thinset cures. Cure times between steps are what stretch the timeline more than the labor itself.

How we got these numbers

National benchmark costs from RSMeans, Angi, Fixr, and HomeGuide are adjusted for New Hampshire using two federal datasets: the Bureau of Economic Analysis Regional Price Parity (RPP) index and the Bureau of Labor Statistics (BLS) Occupational Employment and Wage Statistics. New Hampshire's RPP is 1.0 (national baseline = 100) and its BLS labor adjustment factor is 1.05. Higher RPP means goods and services cost more relative to the national average; the BLS factor scales contractor labor rates to local wage levels. We blend these two adjustments, weighted 40% RPP, 60% BLS labor, to produce the ranges shown above.

adjusted_cost = national_benchmark × (0.4 × RPP/100 + 0.6 × bls_labor_adj)

RPP(New Hampshire) = 1.0 · BLS adj = 1.05

Build sequence

1
Confirm the subfloor is stiff and flat, then install backer board or an uncoupling membrane.
COMMON MISTAKE
Tiling over a bouncy floor leads to cracked tile and grout.
2
Dry-lay tiles to plan the layout and avoid thin slivers at the walls.
3
Comb thinset with a notched trowel and set tiles with even spacers.
COMMON MISTAKE
Too little thinset coverage leaves hollow spots that crack under load.
4
Let the thinset cure, then mix and float grout into the joints.
5
Clean the haze, let it cure, and seal the grout if needed.
