How to Replace One Tile on Backsplash

Replacing a single damaged tile in a backsplash can seem like a daunting task, but with the right preparation and tools, it is actually quite manageable as a DIY project. While the specific steps will vary slightly depending on the type of tile and installation method used, the general process involves removing the damaged tile, preparing the surface, cutting a replacement tile to fit, and installing the new tile. With some care and patience, you can replace just one backsplash tile and have it look seamless in the finished result.

What You’ll Need

Before starting this project, make sure you have the necessary tools and materials on hand:

  • Replacement tile – Get a tile that matches the size, texture, color, and design of the surrounding tiles as closely as possible. Purchase from the same production lot or brand if feasible.
  • Grout – Match the color of the existing grout as closely as possible. Having leftover grout from the original installation is ideal.
  • Grout sealer – Using a grout sealer will help prevent staining and discoloration.
  • Utility knife – For safely cutting and scraping away existing grout and adhesive.
  • Grout saw – A special saw with a carbide or diamond-grit blade for cleanly cutting ceramic tile.
  • Hammer and chisel – For breaking tile edges and removing chunks of mortar or thinset.
  • Putty knife – Flexible putty knives work well for prying up tiles and scraping surfaces.
  • Tiling trowel – Use the same type of trowel used for the initial installation to apply the mortar or adhesive.
  • Sponge – For wiping away grout and cleaning the surface when done.
  • Safety gear – Eye protection, masks, knee pads, and gloves help protect you while working.
  • Adhesive or mortar – Use the same adhesive or mortar used during the original installation for best results.
  • Painter’s tape – Helps protect surrounding tiles and keep everything neat.
  • Rag – For wiping away dust and debris during the repair work.

With the right tools at hand, you can tackle a single tile replacement project. Always turn off power to outlets near the backsplash before beginning.

Removing the Damaged Tile

Start by carefully getting the damaged tile off the backsplash:

  • Use a utility knife to lightly score around all edges of the grout surrounding the bad tile. This will make it easier to remove the old grout.
  • With a grout saw, cut away the grout around the tile. Cut all the way down to the backing surface.
  • Break apart larger chunks of grout with a hammer and chisel if needed.
  • Insert a putty knife under the bottom edge of the tile and gently twist and pry upward.
  • Work the tile loose, being careful not to harm surrounding tiles. Remove it fully once loose.
  • Use the putty knife to scrape away any remaining grout or adhesive from the now open area on the backsplash.
  • Apply more force when scraping to remove all old residue. Get down to the bare backing surface.
  • Clean the area thoroughly and vacuum away any debris. Examine the open space and backing to plan new tile placement.

The backsplash area should now have an open space surrounded by existing tiles, ready for your replacement tile installation.

Preparing the Surface

It is important to make sure the backsplash surface is clean, dry, and ready for fresh adhesive and the new tile:

  • Use painter’s tape to cover the edges of nearby tiles. This keeps them protected.
  • Vacuum and wipe down the open area again, making sure no debris is left behind.
  • Apply painter’s tape squares to cover any outlets or fixtures near the work area.
  • Ensure the bare backing material is still solidly adhered to the wall. Scrape and re-secure any loosening edges or seams.
  • Check that the open surface is smooth and even. Use a putty knife to flatten any bumps or ridges.
  • If the original installation used cement backerboard, apply fresh thinset mortar before the new tile.
  • For drywall, apply a drywall seam adhesive to edges for stability as needed.

With the backing surface ready, you can move on to cutting and placing the new tile.

Cutting the Replacement Tile

Use the following steps to precisely size and shape the new tile:

  • Lay the replacement tile over the open area on the backsplash.
  • Press it down firmly and use a pencil to trace an outline of the opening onto the back of the tile.
  • Place the tile on a flat, stable surface for cutting. Ensure adequate protection underneath.
  • Using a straight edge as a guide, score the pencil line deeply with the utility knife.
  • Go over the line several times applying firm pressure to create a deep groove.
  • Position the tile so the score line extends just slightly over the edge of the work surface.
  • Press down firmly on the excess portion of the tile to break the tile along the scored cut line.
  • Use a tile nipper tool to cleanly snap odd corners or curves if needed for an exact fit.
  • Set the freshly cut tile in place on the backsplash to test the sizing and make any minor adjustments.
  • Continue this process until the tile fits perfectly within the open area.

Cutting the replacement tile may take a few tries to get just right. Take your time with this step for the best results.

Applying Adhesive and Installing Replacement Tile

Once you have the replacement tile cut to the proper shape and size, it is time to secure it permanently to the backsplash:

  • Apply a layer of thinset mortar or adhesive to the back of the tile, using the tiling trowel just as with the original installation.
  • Apply a matching layer of the same adhesive within the open backsplash area.
  • Carefully set the new tile into place, pressing it firmly into the adhesive. Use a slight twisting motion to ensure maximum adherence.
  • Push down on the tile surface with the trowel head to flatten and evenly spread the adhesive behind the tile.
  • Ensure the surface of the replacement tile is flush with surrounding tiles and that alignment and spacing looks correct.
  • Allow the adhesive to cure fully – usually 24-48 hours. Temporarily tape tile in place if needed.
  • Mix grout according to package directions and apply over the tile edges and surrounding grout lines.
  • Let grout cure fully before water exposure – check package for timeline.

The new tile is now securely installed! You can remove any covering tapes andprepare to clean and seal the grout lines.

Cleaning and Sealing the New Grout

Freshly grouted tiles require some careful cleaning and sealing:

  • Use a damp sponge to gently wipe away excess grout, working diagonally across tiles to avoid pulling grout from joints. Rinse sponge frequently.
  • Allow grout to cure for the time recommended by manufacturer. Do not expose to water until fully cured.
  • Use a soft cloth to wipe any remaining grout haze from tile surfaces once cured.
  • Apply grout sealer to finished grout lines following product directions. Allow sealer time to dry.
  • Use painter’s tape to surround tiles and avoid getting sealer on the tile surfaces.
  • Apply a second coat of sealer for maximum protection.

The newly sealed grout lines should now match the existing grout color while providing protection from stains and moisture. The individual backsplash tile replacement is complete!

Tips for Achieving a Seamless Look

Careful prep work and attention to detail will ensure your new tile blends in seamlessly:

  • Use the same tile size, spacing, pattern, and design as the original backsplash installation.
  • Cut the replacement tile to match original tile edges and shapes as closely as possible.
  • Ensure the new tile lies perfectly flush with surrounding tiles.
  • Maintain consistent grout line widths all the way up to edges of replacement tile.
  • Apply fresh matching grout and sealant to make all grout lines look uniform.
  • Work slowly and carefully. Don’t rush through cutting or adhesive application steps.
  • Keep the work area clean and protected throughout the process.

Frequently Asked Questions About Replacing One Backsplash Tile

Replacing just one backsplash tile may seem like a straightforward task, but it can raise many questions for homeowners attempting it themselves for the first time. Here are answers to some frequently asked questions about this project:

Can I just glue a new tile over the old one?

No, do not attempt to glue a new tile over the damaged one. The new tile will not adhere properly long-term. You need to fully remove the damaged tile and prepare the backsplash surface underneath before attempting a repair.

What tools do I need for one tile replacement?

A grout saw, utility knife, putty knife, tiling trowel, hammer and chisel, sponge, safety gear, adhesive, grout, and grout sealer are the basic tools required. You may also find a tile nipper, rags, painter’s tape, and vacuum helpful too.

How do I match grout color for one replaced tile?

Save leftover grout from the initial installation if possible. Otherwise bring a sample of the grout to a home improvement store to get the closest match. Only grout right around the replaced tile, not the whole backsplash.

Can I use a different tile if I can’t find an exact match?

It’s best to get as close of a match as possible in terms of size, texture, color, and design. Using a noticeably different tile will look awkward and draw the eye.

Is it ok to use a tile just slightly bigger or smaller?

The new tile should fit the opening as precisely as possible. Using a slightly bigger or smaller tile can throw off grout line spacing and the overall look. Take time to cut the tile to the right size.

How long does the adhesive need to dry before grouting?

Adhesive manufacturer directions must be followed exactly, usually 24-48 hours of cure time before grouting can begin. The wall surface material also impacts dry times.

How soon can the new tile get wet after grouting?

Fresh grout needs time to cure fully or it can become discolored. Wait at least 72 hours before exposing completed repair to water or moisture.


Replacing one damaged tile in a backsplash may seem daunting, but when broken down into individual steps it is very manageable as a DIY project. Carefully remove the tile, prepare the surface, cut a replacement, adhere it properly, regrout, clean, and seal. Pay close attention to manufacturer directions for adhesives, mortar, and grout. Match existing tile characteristics and installation methods as closely as possible for a seamless look. Patience and attention to detail will pay off with a successful single tile replacement that looks like new.

How to Tile a Shower Wall – Complete Guide

Tiling a shower or tub surround wall is an excellent upgrade that adds style, water protection, and easy maintenance to a bathroom. The process involves careful preparation, precise tile cutting, proper materials, and attention to detail. Follow this complete tiling guide to transform any bathroom with beautiful new shower walls.

What You’ll Need

Tiling a shower wall is a big project, so be sure you have all the necessary supplies before getting started:

  • Tile – Select wall tile dimensions appropriate for the space that resist moisture and provide grip. Ceramic, porcelain, glass, and natural stone are common options.
  • Backer board – Cement boards provide a waterproof, stable backing surface for tiles. Avoid drywall alone.
  • Thinset mortar – Used to adhere tiles to the backing surface. Look for polymer-modified mortar resistant to moisture.
  • Grout – Waterproof grout designed for wet areas is crucial. Match grout color to your tile.
  • Tiling tools – Including notched trowels, tile cutter, spacers, grout float, and sponges.
  • Adhesive and caulk – Such as 100% silicone to seal joints and gaps.
  • Safety gear – Eye protection, dust mask, knee pads, and gloves for working safely.
  • Drop cloths – Protect the rest of the bathroom during the tiling process.

Ensure you have all necessary materials and tools available before you start. Tiling an entire shower wall is a process.

Preparing the Shower Walls

Preparing the shower walls correctly is crucial for successful tiling. Follow these steps:

Remove Old Surfaces

  • Take down existing wall tile, drywall, or fiberglass surfaces. Remove sink and plumbing fixtures as needed to access walls.
  • Inspect wall structure underneath for moisture damage or issues. Repair or replace any compromised areas.

Deep Clean

  • Thoroughly clean all shower/tub and wall surfaces. Remove any existing adhesive, soap scum, or debris.
  • Disinfect all areas. Ensure surfaces are clean and free of leaks or standing water.

Install Backer Board

  • Cut cement backerboard panels to size and test fit to each wall surface.
  • Screw backerboard sheets to wall studs using cement board screws spaced 6 inches apart across panels and around edges.
  • Tape seams between backerboard sheets using alkaline resistant mesh tape. Embed tape in thinset mortar.

The shower should now have a moisture-resistant cement backer board surface ready for tiling.

Planning Tile Layout

Carefully planning your tile layout is essential for a cohesive look. Consider:

  • Tile dimensions – Smaller tiles allow more intricate patterns but require more grout lines. Larger tiles are faster to install.
  • Pattern and orientation – Grid, herringbone, geometric, or stacked patterns give visual interest. Decide which way tiles will run.
  • Grout line width – Thinner grout lines (1/8 inch) give a smoother look. Wider lines (3/16 inch) are easier for beginners.
  • Edges and accents – Border tiles, niches, shelves, and trim tiles can enhance the design.
  • Symmetry – Measure and map how tile courses will start and end across multiple walls to ensure symmetry.

Having a well thought out tile plan makes the installation process go smoothly. Don’t rush this step.

Cutting and Installing Wall Tiles

Once you have planned out your shower tile design, begin careful installation:

  • Mix thinset mortar according to package directions. Apply to sections of the wall using a notched trowel. Only cover areas you can tile before mortar dries.
  • Cut perimeter and accent tiles to fit using a wet saw or tile cutter. Use tile spacers to ensure even grout line width.
  • Press tiles into the mortar, using light twisting motions to adhere. Align to planned layout and use leveling tools to keep tiles even.
  • Check tiles constantly as you work to ensure proper coverage of mortar, spacing, and alignment.
  • Let mortar cure 24 hours before continuing. Then apply grout between tile joints with a rubber float.
  • Wipe away excess grout with a damp sponge, cleaning diagonally across tiles. Rinse sponge frequently.
  • Seal grout once fully cured, usually 72 hours. Apply silicone caulk in corner joints and gaps.

Take your time during installation for best results in shower tile appearance and longevity.

Tips for Professional Looking Shower Tile

Follow these tips to help your DIY shower tile installation look polished and pro-quality:

  • Maintain the exact same grout line width throughout walls for consistency.
  • Cut accent and border tiles precisely to fit for a seamless look.
  • Keep tiles clean from thinset during installation to minimize grout haze on finish.
  • Use high quality drill bits and take care drilling holes for fixtures or shelves.
  • Use leveling systems often to check tile alignment as you go. Adjust as needed.
  • Seal the grout and caulk all joints to prevent moisture problems down the line.
  • Work slowly and carefully. Don’t rush through steps even if using large format tiles.

By taking extra care at each stage, your custom tiled shower can rival one installed by professionals.

Frequently Asked Questions About Shower Wall Tiling

Tiling a shower area from start to finish brings up many common questions for DIYers. Here are some helpful answers:

What tile material works best in showers?

Porcelain, ceramic, and natural stone tiles stand up well to regular water exposure. Glass tiles also make beautiful shower accents. Avoid using drywall alone behind tiles.

How are cement backerboards installed on shower walls?

Screw backerboard sheets to wall studs every 6 inches around the perimeter and across the field. Tape seams with fiberglass mesh tape and thinset mortar.

Can I use regular drywall instead of cement backerboard?

No, only moisture-resistant surfaces like backerboard should be used behind shower tiles. Drywall alone risks swelling and mold growth when wet.

How do I achieve symmetrically spaced tiles across multiple walls?

Map out the full tile layout before starting so courses align where walls meet. Measure and mark reference points on each wall to ensure tiles line up.

What spacing do I need between tiles for grout lines?

Wall tiles typically have grout line widths from 1/16 to 3/16 inches. Wider spacing is more forgiving for beginners. Use plastic spacers as you lay tile.

How soon can I use the shower after tiling and grouting?

Wait at least 72 hours after grouting to allow full cure before use and water exposure. Check instructions for your specific grout product to be sure.


Installing tile on your shower or tub surround walls provides a stylish, water-resistant, and easy-to-maintain solution for bathroom upgrades. Careful planning, precision cuts, proper materials like backerboard and thinset mortar, and attention to detail will lead to success tiling your shower
