Step 1: Prepare the Space
Take Off Baseboards and Old Floors
First, take off baseboards and old floors to see the subfloor. This makes a smooth surface for your tile.
Use a pry bar to gently remove baseboards without harming walls. If changing carpet, laminate, or vinyl, cut them into smaller pieces and clear away sticky stuff. For old tiles, use a hammer and chisel or a floor scraper to take out tiles and mortar.
Clean the Subfloor Well
Sweep and vacuum the subfloor to remove all dust and dirt. A clean area helps mortar stick right and avoids flaws in the new floor.
Look for Damage or Wetness
Check the subfloor for cracks, holes, or uneven spots. Use a level to find dips or high spots.
- Cracks or holes: Patch them with a compound.
- Uneven spots: Use a leveling compound to make a flat, strong base.
If working on concrete, use a meter to check for wetness. Too much moisture can ruin tiles or grout, so fix wetness issues before continuing.
Put Down Underlayment or Cement Board (if needed)
Depending on your subfloor type:
- Wood subfloors: Put down cement board for a stable, water-resistant base.
- Concrete subfloors: Usually don’t need underlayment, but a crack isolation or waterproofing layer might be suggested sometimes.
Attach backer board panels following maker’s instructions, 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 center of the room. Use a tape measure to find the middle of each wall and snap chalk lines across the floor in both directions. The spot where the lines meet is where you should begin laying tiles. This helps your tile layout look even and balanced.
Choose Your Tile Layout Pattern
If you’re new to DIY, simple patterns are best:
- Straight Lay (Grid Pattern): Tiles are lined up straight to the walls, forming neat, uniform rows.
- Diagonal (Diamond Pattern): Tiles are set at a 45-degree angle to the walls for a more lively look — a bit harder but still doable.
Note: Complex designs like herringbone, chevron, or parquet patterns need more skill and aren’t recommended 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 the tiles will meet walls, cabinets, or doors.
- Make changes to avoid thin tile pieces at room edges (which can look odd and might crack easily).
Spacing and Grout Lines
Put spacers between the tiles during the dry fit to create even grout lines. Common spacer sizes are 1/8 inch or 3/16 inch, depending on the tile size and style.
Calculate Tile Quantity (Add 10–15% for Waste)
Measure 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 rooms with many cuts) to account for cuts, mistakes, and future repairs.
- Order that amount of tile to make sure you have enough for the whole project.
Step 3: Choose Your Installation Method
For most tile flooring jobs, especially big ones, thinset mortar is the best way to install tiles. It sticks tiles firmly to the floor.
Common Methods:
- Thinset Mortar (Recommended)
This cement glue works well for floor tiles. It handles weight, water, and temperature changes. Many people use thinset because it is strong and reliable. - Tile Adhesive (Mastic)
Good for small DIY areas or wall tiles in dry spots. It’s easy to use but not strong enough for most floor tiles or wet places.
Note: For floor tiles, thinset is usually the best and safest option.
| Installation Method | Best For | Strength & Durability | DIY Friendliness | Notes |
|---|---|---|---|---|
| Thinset Mortar | Floor tiles, wet places (bathrooms, kitchens), big areas | ⭐⭐⭐⭐⭐ (Excellent) | Moderate | Standard choice for tile floors. Handles water, weight, and movement well. |
| Tile Adhesive (Mastic) | Small dry areas, wall tiles | ⭐⭐ (Limited) | Easy | Not good for floor tiles or wet places. Quicker to use but less strong. |
Step 4: Mix Mortar and Apply to Subfloor
Mix the Mortar
First, mix the thinset mortar as the instructions say. Use a clean bucket and a drill with a mixing paddle to make it smooth and without lumps. Let it sit for a few minutes, then mix again before using.
Spread the Mortar
With a notched trowel, spread the mortar evenly on a small part of the subfloor. Hold the trowel at a 45-degree angle to make even ridges. These ridges help the tile stick well and make sure the installation is level.
Work in Small Sections
Only cover as much area as you can tile in about 10–15 minutes. This stops the mortar from drying before the tiles are placed.
Pro Tip:
For bigger tiles, put a thin layer of mortar on the back of the tile for better sticking, especially for tiles over 12 inches.
Step 5: Lay the First Tiles
Starting right is important for the whole project.
Begin at Your Layout Center Point
Use chalk lines from your plan to start in the middle of the room or at a key spot. This helps tiles spread evenly.
Set the First Tile
Put the first tile in the mortar. Press hard and twist a bit to make it stick well.
Use Tile Spacers
Put spacers between tiles to keep gaps even for grout. This makes it look neat and professional.
Check for Level
After a few tiles, use a level to make sure the surface is flat. Adjust before the mortar dries.
Pro Tip:
Work in small areas so the mortar stays wet until tiles are placed!
Step 6: Cutting Tiles to Fit
Cutting well is important for a nice finish.
Measure and Mark
Use a tape measure to find 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 detailed cuts, use a wet saw or an angle grinder with a diamond blade.
Cut in a Safe Area
Always cut outside or in a place with good air flow to avoid dust. Wear safety glasses and gloves for safety.
Pro Tip:
Measure twice before cutting to save materials and fit perfectly!
Step 7: Install Remaining Tiles and Let Mortar Cure
After placing the first tiles, keep setting the rest in rows. Start from your initial spot and use spacers for even grout lines. Make sure tiles are level, adjusting if needed to avoid uneven spots.
Don’t walk on new tiles to keep them in place. Work in small areas to stop the mortar from drying too soon.
When all tiles are in, let the mortar set for at least 24 hours (or as the maker suggests) before grouting. This step is key for a strong, long-lasting tile floor.
Step 8: Apply Grout
After the mortar is set, grout the spaces between the tiles:
Mix the Grout
Follow the package instructions to mix the grout until it is smooth like peanut butter.Spread Grout with a Float
Hold a rubber grout float at a 45° angle to spread grout over the tiles. Press hard to fill all the spaces.Remove Extra Grout
After filling, hold the float at an angle and scrape off extra grout from the tiles.Clean Tiles with a Damp Sponge
Wait 10 to 15 minutes, then gently clean the tiles with a damp sponge. Rinse the sponge often and keep grout in the spaces.Final Buffing
When the grout starts to haze (after 30–60 minutes), use a dry microfiber cloth to buff the tiles and remove the haze.
Step 9: Clean and Seal the Floor
Remove Grout Haze
After the grout dries (usually 24 to 48 hours), a hazy layer shows up on the tiles. Use a damp sponge or special grout haze remover to gently clean the tiles. Be careful not to touch the grout lines.
Apply Grout Sealer
If the grout maker suggests it, apply a grout sealer to protect from water, stains, and mold. Use a small brush or a bottle with a roller tip for accuracy. Let the sealer dry completely as per the instructions.
Reinstall Baseboards and Transition Strips
When everything is clean and dry, put back your baseboards and add transition strips between different floors or rooms. This makes your new tile floor look nice and professional.

Pro Tips for a Successful Tile Flooring Installation
Want pro results for your DIY tile project? Remember these tips:
- Save time by setting up your tools and tiles first. Place them where you can easily reach.
- Use a good wet saw for neat cuts, especially on porcelain tiles.
- Mix small amounts of mortar and grout. This keeps them from drying out too soon.
- Check the level often with a spirit level as you lay the tiles.
- Work in small areas. This stops the mortar from drying before placing tiles.
- Reduce breakage. Cut tiles slowly and wear safety glasses.
Common Mistakes to Avoid When Installing Tile Flooring
Even skilled DIYers can make these errors:
- Skipping leveling the subfloor. An uneven subfloor can crack tiles and create uneven lines.
- Forgetting spacers. Uneven grout lines don’t look professional.
- Walking on tiles before the mortar sets. This can move tiles and mess up alignment.
- Using too much or too little mortar. This affects adhesion and can make tiles uneven.
- Not cleaning grout haze quickly. Letting it sit too long makes it tough to remove.
