Tired of staring at beige tiles from the ’90s? Let’s bring your bathroom into the present—no demolition required.

Why Updating Bathroom Tiles Matters

Tiles play a major role in your bathroom’s appearance and overall vibe. Outdated or damaged tiles can make your bathroom feel dirty, cramped, or neglected—even when it’s clean. Updating old tiles improves visual appeal, boosts home value, and enhances comfort without the cost and mess of a full tile replacement. Even small updates like painting, regrouting, or using peel-and-stick overlays can dramatically improve the space and protect surfaces from moisture and wear.

Step-by-Step Guide to Updating Old Bathroom Tiles

1. Clean and Prep the Tile Surface

No matter which method you choose, the first step is always a deep clean. Use a tile-safe cleaner to remove:

  • Soap scum
  • Mold or mildew
  • Grime buildup
  • Old polish or sealants

Mix white vinegar with warm water or use a bathroom-specific tile cleaner. Scrub with a soft brush or sponge. Rinse thoroughly and let the tiles dry completely.

Tip: If there’s mold or mildew in the grout, treat it with a bleach-based grout cleaner before moving forward.

2. Method 1: Paint Your Bathroom Tiles

Painting is one of the most popular ways to update old tiles on a budget.

What You’ll Need:

  • Tile paint or epoxy paint
  • Primer (if required by the paint brand)
  • Painter’s tape
  • Sandpaper (fine grit)
  • Paint rollers and brushes
  • Ventilation mask and gloves

How to Do It:

  1. Lightly sand the tile surface to help the paint adhere.
  2. Tape off edges, fixtures, and trim to avoid splatters.
  3. Apply a coat of primer if needed, then let it dry.
  4. Roll on your tile paint in smooth, even strokes.
  5. Apply 2–3 coats, allowing full drying time between each.

Pro tip: Use a small brush for grout lines or tough-to-reach corners.

Best For:

  • Ceramic or porcelain wall tiles
  • Splash zones (not recommended for floors unless labeled floor-safe)

Avoid high-traffic floor tiles unless using a specially formulated tile & floor epoxy.

3. Method 2: Regrout or Refresh the Grout

Sometimes, the tiles are fine—it’s the dingy grout making the space look tired.

What You’ll Need:

  • Grout saw or removal tool
  • Premixed grout
  • Grout float
  • Sponge and bucket
  • Grout sealer

How to Do It:

  1. Scrape out the top layer of old grout with a grout saw.
  2. Wipe the tiles clean to remove dust.
  3. Apply new grout using a float at a 45° angle.
  4. Wipe off excess with a damp sponge before it sets.
  5. After drying (typically 24 hours), seal the grout to prevent staining.

Don’t want to remove the grout? Use a grout pen to “paint” over discolored lines for a fast cosmetic fix.

Best For:

  • Wall or floor tiles with stained or cracked grout
  • Updating the color contrast (e.g., switching from beige to white or gray)

4. Method 3: Use Peel-and-Stick Tile Overlays

Peel-and-stick tile stickers or panels are a renter-friendly and low-mess option to cover outdated tiles with a modern look.

What You’ll Need:

  • Peel-and-stick tiles
  • Ruler and utility knife
  • Cleaning supplies

How to Do It:

  1. Clean and dry the tile thoroughly.
  2. Measure each tile or panel space.
  3. Cut your peel-and-stick tiles to fit using a utility knife.
  4. Press the stickers down firmly, starting from one side and smoothing out bubbles.

Make sure the stickers are labeled as moisture-resistant and suitable for bathrooms.

Best For:

  • Shower walls, backsplashes, or sink surrounds
  • Covering old tile without permanent changes

5. Method 4: Add Tile Decals or Borders

Don’t want to paint the entire bathroom? Try decorative decals or border tile stickers to add pops of style without a full update.

Ideas Include:

  • Adding a colorful border around the top row of tile
  • Creating a mosaic-look panel behind the sink
  • Using stencil-style decals to mimic encaustic tiles

These are easy to apply and remove and can be changed seasonally or with decor updates.

Perfect for renters or those who want a quick style boost without commitment.

6. Method 5: Replace a Few Key Tiles

If most of your tiles are still in good shape, consider replacing just a few:

  • Cracked or chipped tiles
  • An accent row or square
  • Tiles behind the vanity or toilet

This gives your bathroom an updated look with minimal labor and cost. Just make sure to match the tile size and thickness or go for a deliberately contrasting accent.

Tip: Use this method to introduce a pop of color, pattern, or texture.

Common Mistakes to Avoid

Mistake 1: Skipping Surface Prep

Dirty or slick tiles won’t hold paint or decals.
Solution: Always clean and sand tiles first to ensure adhesion.

Mistake 2: Using the Wrong Paint

Wall paint won’t work on tiles.
Solution: Use epoxy or tile-specific paints that are designed for wet environments.

Mistake 3: Not Sealing the Grout

Fresh grout can quickly stain without protection.
Solution: Always seal new grout 24–48 hours after application.

Mistake 4: Using Floor Tile Stickers in the Shower

These aren’t waterproof enough for soaking areas.
Solution: Stick to wall-safe or splash-safe products only.

Mistake 5: Applying Decals Over Textured Tile

Raised or beveled tiles won’t allow stickers to adhere properly.
Solution: Use decals only on smooth tile surfaces.

Extra Tips & Bathroom Hacks

  • Combine methods for a full makeover: Paint the tiles, refresh the grout, and add decals for a layered update.
  • Match your tile update with fresh accessories: New towels, a rug, or a mirror can enhance your new tile style.
  • Use neutral colors for resale appeal: If selling your home soon, stick to whites, grays, or soft earth tones.
