How to Measure a Floor for Tile Installation
Before you can learn how to tile a floor, you need to learn how to measure a floor for tile installation. It seems simple enough, just measure the length and the width of your space, right? But what if it’s an irregular shape? In that case, you divide the surface into multiple smaller sections you can easily measure. Use the smallest and most precise increment possible, preferably millimeters.
Now you can do the math yourself, but it’s easier to use our Surface Area Calculator. Go to any product page, and under Calculator, simply input your measurements and you automatically get how much tile you need, how many boxes you need to order, and how much it costs. It enables you to calculate different sections separately, for the most accurate measurement possible. It’s the most precise result you can get, avoiding both financial and material waste. This feature is available for every kind of tile in the TileTopia catalog.
How to Prepare the Subfloor for Floor Tiling
Before you grab your tiles and get to work, there’s some surface prep work to carry out. The subfloor needs to be cleaned and stabilized according to material.
🪨 Concrete Floors
When considering how to tile a concrete floor, make sure to remove any grease or possible adhesives, especially if you’ve removed an existing tile floor. Any damage, like holes or cracks have to be filled in and repaired. At the end, your floor should have no structural flaws and it should be level.
🪵 Wood Floors
Like the concrete floor, you first want to check for - and repair - any unevenness. Nail down loose floor boards and fill in gaps. Wood floors will need a tile backer or a plywood board to ensure they’re level. Clean everything thoroughly.
Do You Need to Remove an Existing Tile Floor?
Ideally, you would remove any existing tile before you start applying a new tile floor. However, there are exceptions and times when you can get away with tiling over tile and it can be a time-saving and cost-saving solution when figuring out how to tile a floor quickly.
You don't need to remove an existing tile floor:
- If the tiles don’t sound hollow; if they’re stuck on properly and undamaged.
- If the tiles are level and clean.
- If it’s a small area.
You need to remove an existing tile floor:
- If you’re tiling an extended surface; that leaves way more room for issues, down the line.
- If the tiles are cracked or otherwise damaged.
- If the tiles ring hollow; that means they’re not properly secured to the ground and can cause damage to the layer on top as well.
How to Lay Tile on a Floor (Step-by-Step)
After all that prep, you're finally ready to learn how to tile a floor.
Plan the layout
The most important thing in floor tile installation is meticulously planning your steps. First, you plan out the tile layout. Start in the middle and start placing tiles in order, in rows, until you reach the walls. Map out your application in a way that allows you to exit the room without walking across freshly laid tiles.
At this point, you’ll usually have small gaps at the edges or in corners, especially if you have an unusually shaped space, uneven walls, or your tile is an unique shape, like hexagon tile, diamond tile, or picket tile, for example. You need to figure out what you need to cut and how much in order to get a seamless result.
Put down adhesive
To spread your adhesive, you need a notched trowel; start with a 1m² surface. Holding the trowel at a 45 degree angle ensures the adhesive is even and there are no air pockets.
How much adhesive and where you apply it depends on the tile, but most tiles are fine to apply directly on the adhesive spread on the floor. But for large format tiles, it’s recommended to also spread some adhesive on the back of each tile - this is known as back buttering. That ensures that they’re properly adhering to the surface.
Lay tiles
When learning how to install a tile floor, the actual process of laying tile is the most important. You place your tile on top of the adhesive with firm pressure and twist lightly to make sure that your tile is properly fixed. To make sure it’s level, adjust its position and check with your spirit level.
When you’re happy with the position, you can apply the tile spacers. You want to really embed them into the adhesive, so they’ll be easily covered in grout. Repeat for all your tiles until you’ve covered the surface.
Cut tiles
To cut tiles, you have a few tool options, depending on the job and the type of tile:
Manual Tile Cutter
- Good for ceramic & porcelain tiles
- Best for straight cuts
- Less expensive than an electric tile cutter
Electric Tile Cutter (Wet Saw)
- Cooled with water to prevent cracks and dust
- Good for porcelain, ceramic, and even stone
- Can cut thicker tiles
Angle Grinder
- Recommended for ceramic & porcelain only
- Able to cut thicker tiles
- Difficult to cut straight
- Great for angles and curves
Tile Nippers
- Slow process if there are lots of details
- Best for unusual shapes and curves
Tile Scribe
- Suitable for thin ceramic tiles
- Not meant for big cuts
- Affordable
Grouting, Sealing, and Finishing Your Tile Floor
Wait for the adhesive to set completely before you start grouting. Installing tile flooring is an exercise in patience.
Let adhesive set completely
Work between tiles, wipe excess
Let grout dry completely
Seal grout to prevent mold & stains
Add tile trim for a seamless finish
Grouting is a simple process, you just work it in between the tiles and make sure to wipe away the excess. Sealing tile is not typically necessary, but grout is porous, so it requires sealing to prevent mold and stains. But you have to wait for it to dry completely before you seal it. For a seamless, professional finish, we recommend complementary tile trim.
How to Tile a Bathroom Floor vs. a Kitchen Floor
The process of how to tile a kitchen floor is largely the same way you tile a bathroom floor, but there are some differences in the floor tiling process, mostly related to prep. Wood subfloors require tile backer boards for a flat, even surface, and if you're tiling a bathroom floor, you'll want to use a special one that's meant for wet environments.
Both spaces are prone to spills or humidity, so they both require non-slip floor tile. But it's especially crucial in the bathroom, particularly for a walk-in shower.
Bathroom floors benefit from smaller tiles and more grout lines for extra grip.
Use a tile backer board rated for wet environments on wood subfloors.
It's more important for kitchen tiles to be durable and heat resistant.
Kitchen floors favor the easy cleaning of large format tiles with fewer grout lines.
Scale can also be different — larger tiles mean a cleaner, easier-to-maintain surface.
