Bathroom Tile Replacement: Costs and Process

Replacing bathroom tile is one of the most transformative renovations you can do — and one of the most labor-intensive. In 2026, retiling a bathroom costs $10–$50 per square foot fully installed, with most homeowners spending $1,500–$5,000 for floors and $3,000–$10,000 when walls and shower surround are included, according to Angi and This Old House. This guide breaks down the costs by surface, walks through the installation process phase by phase, and explains where cutting corners leads to expensive failures.

Cost estimates reflect 2026 national averages. Prices vary by region, tile material, and project complexity.

Cost Breakdown by Surface

Surface	Area (Typical)	Material Cost/Sq Ft	Installation Cost/Sq Ft	Total Installed/Sq Ft
Bathroom floor	35–75 sq ft	$2–$15	$8–$20	$10–$35
Shower walls	50–80 sq ft	$2–$20	$8–$25	$10–$45
Shower floor	9–16 sq ft	$3–$20	$10–$30	$13–$50
Tub surround	40–60 sq ft	$2–$15	$8–$20	$10–$35
Backsplash	5–15 sq ft	$3–$30	$10–$25	$13–$55

Additional Costs

Item	Cost Range	Notes
Old tile removal	$2–$7/sq ft	More for mortar-bed tile
Backer board installation	$3–$6/sq ft	Required for shower walls
Waterproofing membrane	$1–$10/sq ft	Critical in wet areas — see Bathroom Waterproofing Guide
Grout (sanded or unsanded)	$0.50–$2/sq ft	Epoxy grout costs more but resists staining
Trim and edge pieces	$3–$15/linear ft	Bullnose, pencil liner, Schluter trim

Tile Material Costs

The material you choose is the biggest variable in your budget. See Best Bathroom Tile Materials Compared for a full comparison.

Material	Cost per Sq Ft	Durability	Water Resistance	Best For
Ceramic	$1–$5	Good	Good (glazed)	Floors, walls, budget projects
Porcelain	$3–$10	Excellent	Excellent	Floors, shower walls, high-traffic
Natural stone (marble, slate)	$7–$20	Varies	Moderate (needs sealing)	Accent walls, luxury showers
Glass/mosaic	$10–$30	Good	Excellent	Accent strips, shower niches
Large-format porcelain	$5–$15	Excellent	Excellent	Modern bathrooms, fewer grout lines

The Tile Replacement Process

Phase 1: Demolition (1–2 Days)

Protect the bathroom — Cover the vanity, toilet, and drain openings with plastic sheeting and painter’s tape. Lay a drop cloth on areas you are not tiling.
Remove old tile — Use a hammer and cold chisel for small areas or a rotary hammer with a chisel bit for large surfaces. Work from the top down on walls.
Remove old backer board — If the existing cement board or drywall behind the tile is damaged, it needs to come out. Greenboard (moisture-resistant drywall) in shower areas should be replaced with cement board.
Inspect the substrate — Check for mold, rot, and water damage. If you find structural damage, hire a licensed professional to assess and repair before proceeding.

Tile demolition generates significant dust. Wear safety glasses, a dust mask (N95 minimum), and heavy gloves. Cover vent openings to prevent dust from spreading through the HVAC system.

Phase 2: Substrate Preparation (1–2 Days)

Install cement backer board on shower walls and around the tub. Screw it into studs every 8 inches with cement board screws.
Tape and thin-set the seams — Apply alkali-resistant mesh tape over all backer board joints, then skim with thin-set mortar.
Apply waterproofing — This is the most critical step for shower areas. Options include liquid membrane (RedGard, Hydroban), sheet membrane (Schluter Kerdi), or foam board (Kerdi-Board). See Bathroom Waterproofing Guide for detailed methods.
Check the floor for level — Use a 6-foot straightedge. Fill low spots with self-leveling compound (up to 1 inch) or floor patch.

Hire a licensed professional for waterproofing in shower areas. Improper waterproofing is the number-one cause of tile failure and leads to mold and structural damage.

Phase 3: Tile Installation (3–7 Days)

Dry-lay the tile — Arrange tiles on the floor or hold them against the wall to plan the layout, centering cuts and avoiding slivers less than half a tile wide.
Mix thin-set mortar — Use modified thin-set for most tiles, unmodified thin-set over Schluter membranes (per manufacturer instructions).
Apply thin-set and set tiles — Use the appropriate trowel size (1/4-inch notch for small tiles, 1/2-inch for large format). Back-butter large-format tiles for full coverage.
Use tile spacers — 1/16-inch for minimal grout lines, 1/8-inch for standard, 3/16-inch for a traditional look.
Cut tiles — A wet saw handles straight cuts; a hole saw or angle grinder with a diamond blade handles plumbing penetrations.
Let thin-set cure — Wait 24 hours minimum before grouting. Longer in humid conditions.

Phase 4: Grouting and Caulking (1–2 Days)

Apply grout — Spread grout diagonally across tile joints with a rubber float. Wipe excess with a damp sponge after 15–20 minutes.
Seal the grout — Apply penetrating grout sealer after the grout cures fully (48–72 hours for cement grout). Epoxy grout does not need sealing.
Caulk all change-of-plane joints — Where the wall meets the floor, where the wall meets the tub, and inside corners. Use 100% silicone caulk in a color matching the grout. See Grout vs. Caulk Guide.

DIY vs. Professional Installation

Factor	DIY	Professional
Cost (labor)	$0	$8–$25/sq ft
Time	2–3x longer	Faster, experienced crew
Waterproofing	Risk of errors	Warranty-backed
Tile cuts	Learning curve	Precise, efficient
Best for	Small floor areas, accent walls	Shower enclosures, full rooms

Bottom line: Floor tile in a dry area is an achievable DIY project. Shower tile installation — where waterproofing is critical — is best left to professionals. The cost of fixing a failed waterproofing job ($3,000–$10,000+) far exceeds the labor savings from DIYing it.

How Long Does Retiling Take?

Project	Pro Timeline	DIY Timeline
Floor only (50 sq ft)	2–3 days	3–5 days
Tub surround	3–4 days	5–7 days
Full shower (walls + floor)	5–8 days	8–14 days
Entire bathroom (floor + shower)	7–10 days	12–20 days

Allow additional time for tile removal (1–2 days) and waterproofing cure time (24–48 hours).

Bottom Line

Retiling a bathroom costs $10–$50 per square foot installed, with the total depending on which surfaces you tile and the material you choose. The process requires careful substrate prep, proper waterproofing in wet areas, and patience during curing. Hire a professional for shower enclosures where waterproofing is critical, and consider DIY for straightforward floor tile in dry areas.
