Step 1: Prepare the Space
Take Off Baseboards and Old Flooring
First, remove the baseboards and old flooring to see the subfloor. This gives you a smooth surface for tile installation.
Use a pry bar to take off baseboards without harming the walls. If changing carpet, laminate, or vinyl, cut them into small pieces and remove all sticky stuff. For old tiles, use a hammer and chisel or a floor scraper to lift and remove tiles and mortar.
Clean Subfloor Well
Sweep and vacuum to get rid of dust, dirt, and debris. A clean surface helps mortar stick and stops mistakes in your new floor.
Check for Damage or Wetness
Look for cracks, holes, or uneven spots in the subfloor. Use a level to find dips or bumps.
- Cracks or holes: Fill them with patching compound.
- Uneven spots: Use floor leveling compound to make a flat, stable base.
If you have concrete, use a moisture meter to check for wetness. Too much moisture can cause tile or grout problems, so fix any wetness before continuing.
Put Down Underlayment or Cement Backer Board (if needed)
Depending on your subfloor type:
- Wood subfloors: Add cement backer board for a stable, water-resistant base.
- Concrete subfloors: Usually don’t need underlayment, but you may want a crack isolation membrane or waterproofing membrane sometimes.
Attach backer board panels as the maker says, using the right screws and leaving gaps between panels.
Step 2: Plan Your Tile Layout
Find the Center of the Room and Mark Guidelines
Start by finding the room’s exact center. Measure the middle of each wall and use chalk lines to mark the floor in both directions. Where the lines meet is where you start laying tiles, helping your layout look even and balanced.
Choose Your Tile Layout Pattern
If you’re new to this, simple patterns are best:
- Straight Lay (Grid Pattern): Tiles line up with the walls, making neat rows.
- Diagonal (Diamond Pattern): Tiles are placed at a 45-degree angle for a dynamic look—it’s a bit harder but doable.
Note: Complex designs like herringbone or parquet are tough and not for beginners.
Dry-Fit Tiles to Check Alignment
Lay a few rows of tiles without mortar (this is called dry-fitting). This lets you:
- Check alignment and spacing.
- See how tiles meet walls, cabinets, or doorways.
- Adjust to avoid thin tile pieces at edges, which can look bad and crack easily.
Spacing and Grout Lines
Use spacers between tiles during the dry fit for even grout lines. Common sizes are 1/8 inch or 3/16 inch, depending on the tiles.
Calculate Tile Quantity (Add 10–15% for Waste)
Find the room’s square footage (length × width). Then:
- Multiply the total square footage by 1.10 (for simple layouts) or 1.15 (for diagonal or tricky cuts) to account for cuts, mistakes, and future repairs.
- Order that amount so you have enough tiles for the project.
Step 3: Choose Your Installation Method
For most tile floor projects, especially big ones, thinset mortar is the best way to install tiles. It makes a strong, lasting bond between the tiles and the floor.
Common Methods:
- Thinset Mortar (Recommended)
This cement-based glue is great for floor tiles. It handles weight, moisture, and heat changes well. Most DIYers and pros use thinset because it’s strong and reliable. - Tile Adhesive (Mastic)
Good for small DIY areas or wall tiles in dry places. It’s easier to use but not strong enough for most floor tiles or wet places.
Note: For floor tiles, thinset is usually the best and safest choice.
| Installation Method | Best For | Strength & Durability | DIY Friendliness | Notes |
|---|---|---|---|---|
| Thinset Mortar | Floor tiles, wet places (bathrooms, kitchens), big spaces | ⭐⭐⭐⭐⭐ (Excellent) | Moderate | Industry standard for tile flooring. Handles moisture, weight, and movement. |
| Tile Adhesive (Mastic) | Small dry places, wall tiles | ⭐⭐ (Limited) | Easy | Not recommended for floor tiles or high-moisture areas. Faster to apply but less durable. |
Step 4: Mix Mortar and Apply to Subfloor
Mix the Mortar
First, mix the thinset mortar as the maker says. Use a clean bucket and a mixing paddle on a drill to make it smooth without lumps. Let it sit for a few minutes, then mix again before using.
Spread the Mortar
Use a notched trowel to spread the mortar evenly on a small part of the floor. Hold the trowel at a 45-degree angle to make even ridges. These ridges help the tile stick well and stay level.
Work in Small Sections
Only spread mortar on areas you can tile in 10–15 minutes. This stops the mortar from drying too early.
Pro Tip:
For bigger tiles, put a thin layer of mortar on the back of the tile for better sticking, especially for tiles bigger than 12 inches.
Step 5: Lay the First Tiles
Starting the right way helps the whole project.
Start at the Center Point
Use chalk lines from your planning. Begin at the room’s center or a main focus point. This makes sure tiles are spread evenly.
Place the First Tile
Put the first tile into the mortar. Press down and twist a bit to make it stick well.
Use Tile Spacers
Put spacers between tiles to keep even gaps for grout. This gives a neat, professional look.
Check for Level
After laying a few tiles, use a level to make sure it’s flat. Adjust if needed before the mortar dries.
Pro Tip:
Work in small areas so the mortar stays wet until tiles are set!
Step 6: Cutting Tiles to Fit
Cutting accurately is important for a nice, professional finish.
Measure and Mark
Use a tape measure to find out the size of the tile piece you need. Mark the line clearly with a pencil or wax pencil.
Choose the Right Tool
For straight cuts, use a manual tile cutter.
For curved or tricky cuts, use a wet saw or an angle grinder with a diamond blade.
Cut in a Safe Area
Always cut outdoors or in a space with good airflow to avoid dust. Wear safety glasses and gloves to stay safe.
Pro Tip:
Measure twice before cutting to avoid mistakes and get a perfect fit!
Step 7: Install Remaining Tiles and Let Mortar Cure
Start by placing the first tiles, then keep adding more tiles in rows. Begin from your starting point, and use spacers to keep grout lines even. Make sure tiles are level, adjusting as needed to avoid uneven areas.
As you lay tiles, don’t walk on them to avoid movement. Work in small sections to make sure the mortar stays wet until tiles are set.
Once all tiles are in place, let the mortar cure for at least 24 hours (or follow the manufacturer’s guidelines) before grouting. Curing properly is key for a strong and lasting tile floor.
Step 8: Apply Grout
After the mortar is set, grout the spaces between tiles:
Mix the Grout
Mix the grout as the package says until it is smooth like peanut butter.Spread Grout Using a Float
Use a rubber float at a 45° angle to spread grout over the tiles. Press hard so the grout fills the spaces well.Remove Excess Grout
After filling the spaces, hold the float at an angle to scrape off extra grout from the tiles.Clean the Tiles with a Damp Sponge
Wait 10 to 15 minutes, then gently clean the tiles with a damp sponge. Rinse often and keep grout in the spaces.Final Buffing
When a haze forms on the tile (after 30–60 minutes), buff with a dry microfiber cloth to clear any remaining haze.
Step 9: Clean and Seal the Floor
Remove Grout Haze
Once the grout dries (usually 24 to 48 hours), a hazy layer will show up on the tiles. Use a damp sponge or grout haze remover to gently wipe the tiles. Be careful not to touch the grout lines.
Apply Grout Sealer
If suggested by the grout maker, add a grout sealer to protect from water, stains, and mold. Use a small brush or a sealer bottle with a roller tip for accuracy. Let the sealer fully dry following the instructions.
Reinstall Baseboards and Transition Strips
When everything is clean and dry, put back the baseboards and add any transition strips needed between different floors or rooms. This makes your tile floor look neat and professional.

Pro Tips for a Successful Tile Flooring Installation
Want great results from your DIY tile project? Keep these tips in mind:
- Save time by organizing tools and tiles first. Put tiles and tools within easy reach.
- Use a good wet saw for clean cuts, especially on porcelain tiles.
- Mix small batches of mortar and grout. This stops them from drying out too soon.
- Check for level often with a spirit level as you lay tiles.
- Work in small areas. This keeps the mortar from drying before placing tiles.
- Minimize breakage. Cut tiles slowly and wear safety glasses.
Common Mistakes to Avoid When Installing Tile Flooring
Even experienced DIYers can make these mistakes:
- Skipping subfloor leveling. An uneven subfloor can crack tiles and cause uneven lines.
- Forgetting spacers. Uneven grout lines make it look unprofessional.
- Walking on tiles before the mortar cures. This can move tiles and mess up alignment.
- Using too much or too little mortar. This causes poor adhesion or uneven tiles.
- Not cleaning grout haze quickly. If left too long, grout haze becomes very hard to clean.
