Steps to Install a Tile Floor

(hover over the links to learn more about the article)

Step 1 : Checking the Subfloor

There’s a lot of confusion about what constitutes a suitable subfloor for tile and what substrates you can (and cannot) tile over. The majority of installations take place over a wood or concrete subfloor, and the two big concerns involve too much deflection and movement from seasonal changes. Read the article at that link to learn what criteria your subfloor should meet before laying tile.

Step 2: Installing Radiant Heating Wire (Optional)

Installing a heating element is a great upgrade for a tile floor, and installers are being asked to install more and more heated floors. Floors can be heated in a number of ways, and we recommend putting down radiant heat and covering it with mortar or pouring self-leveling mortar (SLM).

Step 3: Level (Flatten) the Subfloor

Professional tile contractors estimate that 90% of all remodel jobs require flattening the floor to eliminate peaks and valleys. This is an important step that is often overlooked, and an uneven floor can result in protruding corners or even broken tiles. In this article, Jim and Rich describe how to “level” an uneven wood or concrete subfloor.

Step 4: Installing Underlayment

A tile floor is only as good as the underlayment beneath it. Commonly cement board is installed over a bed of mortar. Another option is to install Schluter DITRA underlayment which serves as an uncoupling membrane, eliminating some of the major causes for cracked and delaminated tile. The guys prefer DITRA; however, it adds time and cost so they don’t use it on all jobs.

Step 5: Marking Guides

Marking accurate guides makes laying tile much easier because you can pre-cut all the tiles and eliminate the need for spacers. Jim and Rich snap chalk lines to set up a grid, and the result is perfectly straight tiles and joints.

Step 6: Laying Tile

With the proper prep work, laying tile is an easy matter. The guys pre-cut all the tiles around the perimeter, support posts, steps and doors, and they lay the tile according to their guides. Mortar in the joints is a common problem, but Jim and Rich have a great trick for eliminating excess mortar.

Step 7: Grouting Tile Joints

Grouting the joints is one of the last steps before the tile install is complete, and it really brings the tile together. This article shares how Jim and Rich grout tile joints including what tools and materials they use and a lot of pro tips.

Step 8: Installing Baseboard and Shoe Molding

Install baseboard and shoe molding involves scarf joints, inside corners (which can be cope cut), and outside corners. Quarter round can be an acceptable alternative to shoe molding if you have large gaps.

If you worked hard to sufficiently flatten the floor and make precise cuts, you can eliminate the need for shoe molding altogether.

Tools to Install Tile Flooring

A successful tile installation requires the right tools, and fortunately most of them are relatively inexpensive. The highest price item you’ll need is a tile saw, and this can be rented at your local home improvement center. This list doesn’t include materials like mortar or grout. Check the individual tutorial for material details.

Completed tile installationOther tools you need include:

  • Chalk line
  • Tape measure
  • Level
  • Wax pencil
  • Foxtail brush
  • Hammer
  • Utility knife
  • Screed or straight-edge
  • Jamb saw (or something similar)
  • Corded drill with mixing paddle
  • Buckets
  • Tile saw (or something similar)
  • Notched trowel
  • Flat trowel
  • Grout float
  • Sponge

Where to Purchase Ceramic or Porcelain Tile

Finished tile installationThe old adage that “you get what you pay for” is true with tile. High quality tile is manufactured to be more uniform in size, and that’s important for aligning tile with consistent grout joints. The tile we show here was purchased through a local tile distributor, and we suggest you do the same.

Depending on what you select and where the tile is manufactured, expect to pay at least $3 per square foot. Be sure to purchase boxes with the same batch number or consecutive batch numbers. This helps ensure a consistent color and pattern.

Big box stores also carry tile. However, they usually offer seconds of quality brands and mixed batches. This makes it frustratingly difficult to maintain a uniform look and pattern, especially with smaller grout joints. DIY centers usually have better prices and often offer promotions that small distributors can’t match. If price is your main concern, be sure to check out list our Home Depot Coupons and Lowe’s Coupons before you buy.

    Nice work there, I didn’t noticed that you used Cross Tile Spacers and Leveling System Clips, I’ve done my bathroom on my own by using those. Without of them as beginner I would be lost and I could never level up tiles and make same spaces between tiles.
    Great Instruction, thanks!

  26. First time see the article, but this is a very good guide for installing a tile floor. Good job!

  27. Outdoor@Fact says:

    Thank you for a really helpful guide. One more tip I would like to add is that for tiles that are 12 inch by 12 inch or larger it’s a good idea to back-butter or flat-coat the backs of the tiles with thinset prior to setting the tiles. Actually I did this with my bathroom myself, it looked quite great :))

  28. Max Sayer says:

    I have been thinking about getting tile flooring and wanted to know what the process is like. I had no idea that there were some places that you can and cannot tile over. This is really helpful to know so if I get new tile flooring I know where I can put it.
