Do It Yourself: How to Tile Your Bathroom Floor Like a Pro

Flip Your Bathroom from the Floor Up

Dreaming of a spa-like bathroom, but your old flooring squashes your Zen?

Whether it’s peeling linoleum or outdated vinyl, replacing your bathroom floor will quickly modernize your space. This two to three-day remodeling project will not only impress guests but can also increase your home’s value

Flooring materials for the average bathroom typically cost between $100-$500, depending on your selections. Hiring a professional for the installation can double or triple your expenses, so this project can be a cost-effective option for the intermediate to expert DIYer.

So how do you lay tile yourself? Well, we called in the experts – Allie Bloyd of Builders Surplus and James Upton, the DIY Tile Guy – to provide helpful tips and advice. Let’s start with the supplies.

Supplies Needed For Your DIY Bathroom Tile Project:

Tools Materials
  • Measuring tape
  • Circular saw
  • Drill
  • Grout float
  • Jigsaw
  • Knee pads
  • Measuring tape
  • Mixing bucket
  • Notched trowel
  • Rubber Gloves
  • Safety glasses
  • Sponge
  • Wet tile saw
  • Grout
  • Sealant
  • Thin-set mortar
  • Tile
  • Tile spacers
  • Underlayment

If you don’t have these tools on hand, visit your local home improvement store and ask about tool rentals.

How to Prepare Your Bathroom

In addition to towels, toothbrushes and decorative items, you’ll need to take out some bathroom fixtures to give you room to work. Remove these items to prep your bathroom:

  • Toilet. Place an old rag in the hole to block sewer gas. Depending on the height of your new tile, you may need to install an extension ring over the toilet flange before reinstalling.
  • Vanity. If you plan to replace your sink or vanity now or in the near future, make sure the entire area surrounding the drain pipe is covered to keep it level.
  • Door. Removing the door keeps the space well-ventilated and allows more room to work. Also, you might need to undercut the door before replacing to accommodate the new tile height.
  • Baseboard. This is optional but recommended. Reinstalling baseboards at the end of the project helps cover slight measuring mistakes for a cleaner look.

Prep work complete? Great, let’s move on to the main event.

Here’s How to Install a Tile Floor Step By Step: 

Step One: Measure the Area and Purchase Materials

Measure your bathroom wall-to-wall to figure out how much tile, grout and underlayment to buy. For the correct amount of tile, calculate the square footage of your room. After you select your tile, determine how many tiles you need per square foot. Consider purchasing a few extra tiles to allow for breaks or cutting mistakes.

How to Select Floor Tiles for Bathrooms

More often than not, neutral colors are the way to go, especially if you plan on selling your home. Also, be sure to select a tile that can handle a lot of foot traffic.

“Go for a look that you know you'll love for decades if need be. Something that will still match your vanity if you decide to change it down the road.”

It’s also important to pick a material that can handle water. That means not too slippery or too porous. James Upton, the DIY Tile Guy, points out that some types of tiles easily absorb water, shampoo and soap, making them a bad choice for the bathroom.

“Many times, people want to select a natural stone, such as marble, travertine and granite. While these products look great, more often than not, they are maintenance intensive and people don't usually understand what they are getting themselves into.”
James Upton | DIY Tile Guy

So, what material do the experts recommend? A great option is porcelain. 

“It's more durable than ceramic,” Bloyd says. “If it chips or cracks, it won't be as noticeable because porcelain tile is the same color all the way through typically. Ceramic is usually red or another color in the body with a paint or glaze on top.” 

Step Two: Clean the Area

To keep your new tile from cracking, thoroughly prepare the surface. If you’re removing old tiles, consider renting a renovation dumpster and make sure to vacuum away the dust and debris. 

You can lay tile over linoleum or vinyl. If you go this route, keep these tips in mind:

  • Scrape away loose, peeling ends of linoleum or vinyl and vacuum dust and particles. 
  • Fill cracks or low spots with thin-set. 
  • Scrub the floor with a vinyl floor stripper to dissolve wax and residue, carefully following the label’s instructions. 
  • Use an abrasive scouring pad to texturize the floor’s surface so the underlayment easily sticks when installed.

Pro-Tip: Always wear gloves and eye protection while working with cement and chemical products. These materials can dry out bare skin or cause chemical burns.

Step Three: Install Underlayment


A layer of cement backerboard provides a clean, even surface to lay bathroom tile. Plywood backerboard also works, but experts recommend the sturdier cement option. This will offer the best support for heavy tiles. To install cement backerboard:

  • Cut the cement board into panels with your circular saw to fit your measurements. 
    • Be sure to cut panels at a manageable length to fit through doorways if cutting outside. 
  • Use a jigsaw to cut inside corners and circles for sinks, toilets and other bathroom fixtures. 
  • Lay panels so that four corners never meet at one point. 
  • Using your drill, screw the underlayment to the sub-floor, spacing screws about 6 inches apart to maintain a level surface. 
  • To secure the cement board, you can also opt for a thin-set adhesive. Be sure to read the thin-set’s label and follow instructions carefully.

“Make sure you have a very level subfloor if you're installing stone tile. It's heavier than other tile and can crack if it's not level.”

Step Four: Layout Your Tile

It’s a good idea to dry-lay the tile first to decide on the best layout. Start in the center and work your way out, keeping spaces between the wall and tile even. Don’t begin at a wall. This may seem easier, but you may have to cut tile very thinly at the opposite wall. For best results, here’s how to lay floor tile:

  • Starting from the center, arrange your tile so you use as many whole pieces as possible.
  • Use tile spacers to space tiles evenly.
  • Count and measure the tiles that need to be trimmed to size.
  • Before removing the tiles, use chalk to mark tile placement for reference during installation. 

How to Use Tile Spacers

To achieve a professional look, follow these tips for tile spacers:

  • Consider purchasing a narrow width to minimize maintenance and the likelihood of cracks or stains.
  • Keep the tile spacers in place while the thin-set dries (see below). 
  • Use needle nose pliers to remove tile spacers once completely set.
  • Don’t lay tile spacers flat. This keeps the grout from adequately filling the space.
  • Don’t place tile spacers in corners. This can make removal more difficult.

Step Five: Cut Your Tile and Complete the Layout

Use your tile saw to cut the tiles down to the sizes you measured in the previous step. Test a few before cutting all of them to make sure you have the proper measurements. Dry-lay all cut tiles for a final quality check before installation.

Step Six: Apply Thin-Set Mortar

Remove tiles from your layout section by section and place in an organized pile. Using a notched trowel, spread a thin layer of thin-set mortar in small segments at a time. Replace tiles with the tile spacers so they stay in position. Once the floor is completely covered, let the mortar dry for a full 24 hours.

”Make sure you ‘butter’ the back of your tile when laying floor tile. This is rubbing a thin layer of mortar on the back of your tile in addition to the mortar on the floor. This ensures a better hold.”

Step Seven: Fill Spaces With Grout

The next day, carefully remove the tile spacers. Mix your grout following the manufacturer’s instructions. Using a grout float, neatly fill the spaces between each tile. Once completely applied, wipe away surplus grout using a damp sponge. Allow another 24 hours for the grout to dry, then apply a grout sealer to protect from chips and stains.

Step Eight: Finishing Touches

Reinstall doors, trims and fixtures. Wipe down floors once more and replace rugs and bathroom décor. Voila! Your bathroom is ready for luxurious bubble baths aplenty.
