How to paint bathroom tiles (2026)
Quick Answer
Yes, bathroom tiles can be painted if they are sound, clean and properly prepared, and if you use a coating designed for tiles or high-moisture surfaces. The result depends far more on preparation and curing than on the painting itself: degrease thoroughly, dull the glossy surface, prime if the system requires it, then apply thin even coats and allow full cure before getting the area wet.
Overview
Painting bathroom tiles is usually a cosmetic refresh rather than a permanent like-for-like replacement for new tiles. It works best on wall tiles in lower-wear areas, and is less durable on floors, inside showers, or anywhere that stays wet, gets scrubbed hard, or sees regular impact. The key is to treat it as a coating system, not just a coat of paint: remove soap residue and limescale, repair any failed grout or loose tiles, abrade the glazed surface so the primer or paint can grip, and follow the product instructions exactly for compatibility, recoating and curing. Most failures such as peeling, blistering or patchy coverage happen because the tiles were still contaminated, too glossy, damp behind the surface, or put back into service too soon. If you choose the right product and let it cure properly, painted tiles can smarten up a tired bathroom for a useful period, especially on splashback walls and around basins. If the tiles are cracked, loose, heavily mould-damaged, or the room has ongoing condensation or leaks, fix those problems first; paint will not solve them and may fail quickly.
Who this is for
Homeowners or tenants with permission who want to refresh sound bathroom wall tiles without full retiling, and who are prepared to spend most of the time on cleaning and preparation.
What you’ll need
- Tile paint or bathroom-suitable topcoat approved by the manufacturer for tiles
- Compatible primer if required by the paint system
- Sugar soap or other suitable degreasing cleaner
- Limescale remover suitable for tiles if needed
- Mould remover suitable for bathrooms if needed
- Abrasive paper or sanding pads for deglossing
- Filler or repair product suitable for chips if needed
- Grout repair product if grout is unsound
- Vacuum and clean lint-free cloths
- Masking tape and dust sheets
- Small roller suitable for smooth surfaces
- Paint brush for edges and corners
- Protective gloves and eye protection
- Good ventilation or extraction
Before you start
Check whether the tiles are wall or floor tiles, and whether they are inside a shower or bath enclosure. Many tile paints are better suited to wall tiles and may not be recommended for floors or constant water exposure, so confirm the intended use on the product label or manufacturer website. Make sure tiles are firmly bonded, grout is mostly sound, there are no active leaks, and any mould or condensation problem is being addressed. If the tiles have been treated with silicone polish, wax, or water-repellent products, expect extra cleaning because these can stop paint bonding. Remove or cut out failed sealant first; new sealant is normally applied after painting has fully cured.
Step-by-step
- 1
Check the surface is worth painting
Inspect all tiles, grout lines and edges. Replace or re-fix loose tiles, rake out and repair badly failed grout, and deal with leaks, damp patches or persistent mould before you think about paint. Remove peeling old coatings rather than painting over them.
Why: Paint only sticks as well as the surface underneath. Loose, damp or contaminated substrates cause early failure no matter how good the paint is.
- 2
Clean off grease, soap, limescale and mould
Wash the tiles thoroughly with a suitable degreasing cleaner. Remove soap scum and limescale fully, especially near showers, taps and around the bath. Treat any mould with a bathroom mould remover, then rinse or wipe down as directed by the product instructions and allow the area to dry completely.
Why: Bathroom residues are a major cause of peeling. Paint cannot bond properly through invisible films of soap, grease, polish, mould or mineral deposits.
- 3
Remove sealant and protect surrounding areas
Cut away old silicone sealant where it meets the tiles if it is in the painting area, as paint will not adhere well to silicone. Mask sanitaryware, fittings, trims and adjacent walls, and put down dust sheets.
Why: Silicone contamination repels paint, and masking gives cleaner edges and reduces accidental splashes on glossy fittings.
- 4
Degloss the tile surface
Lightly abrade the glazed tile faces to dull the shine and key the surface. Focus on creating an even, matt scuff rather than gouging the tiles. Vacuum away dust and wipe with a clean damp cloth or tack method recommended by the paint maker, then let dry.
Why: Glazed tiles are very smooth and non-porous. Abrasion gives the primer or paint a mechanical key so it is less likely to chip or peel.
- 5
Prime if your coating system requires it
Apply the specified primer if the manufacturer says one is needed for ceramic, porcelain or glossy surfaces. Work it into grout lines and edges first, then cover the tile faces evenly. Let it dry and, if instructed, recoat within the stated window on the label.
Why: A compatible primer improves adhesion and helps the finish coat bond evenly across both tile faces and porous grout.
- 6
Apply thin, even coats of tile paint
Stir the paint as directed. Cut in around edges and corners, then use a small smooth-surface roller on the tile faces. Apply thin coats rather than trying to cover in one heavy pass, and follow the manufacturer guidance for recoating. Add further coats only as needed for even colour and coverage.
Why: Thin coats level better, cure more reliably and are less prone to runs, soft spots and weak adhesion than heavy coats.
- 7
Allow full cure before normal bathroom use
Keep the room ventilated and avoid steam, splashing, cleaning or reinstalling removed items until the paint has fully cured according to the product instructions. Reapply fresh sanitary-grade sealant only after the coating is ready for it.
Why: Paint may feel dry long before it has hardened. Early water exposure or steam can mark the finish, soften it or break adhesion.
Why this works
Bathroom tile paint succeeds when the coating can both chemically and mechanically bond to a clean, stable, deglossed surface. Preparation removes bond-breaking contamination, abrasion reduces slipperiness of the glaze, and correct priming and curing let the coating harden into a moisture-resistant film.
Common mistakes to avoid
- Painting over soap residue, limescale, silicone contamination or mould
- Skipping abrasion on glossy tiles
- Using ordinary wall paint instead of a product intended for tiles or high-moisture bathrooms
- Applying coats too thickly and getting runs or soft finish
- Painting over loose grout, cracked tiles or damp problems
- Using the shower or cleaning the tiles before the paint has fully cured
- Assuming painted floor tiles or shower enclosure tiles will last as well as new tiles
Troubleshooting
Paint peels when tape is removed or chips easily
The surface was usually contaminated, too glossy, damp, or incompatible with the coating. Remove failed areas, clean thoroughly, abrade again, and repaint using the full manufacturer-recommended system.
Patchy sheen or uneven coverage
This often means inconsistent absorption between grout and tile, or uneven film thickness. Apply another thin coat if the product allows, keeping a wet edge and even roller pressure.
Runs or sagging
Brush or roll them out while still wet. If already dry, let the coating harden, sand the defect smooth, clean off dust and recoat thinly.
Blistering or bubbling
This can be caused by trapped moisture, poor adhesion, or painting in unsuitable conditions. Let the area dry fully, remove loose coating, fix any damp source, then reprepare and repaint.
Mould coming back through grout lines
Clean and treat the mould, then improve extraction and reduce condensation. Paint alone will not solve underlying moisture and ventilation issues.

Alternatives
- Replace only the most visible wall tiles and repaint surrounding walls
- Install bathroom wall panels over suitable prepared surfaces where appropriate
- Refresh grout and sealant only if the tile colour is acceptable but the bathroom looks tired
Pro tips
- Test the full cleaning, abrasion, primer and paint system on an inconspicuous tile first.
- Label and keep the exact products used so you can make compatible touch-ups later.
- Work methodically from top to bottom to avoid leaning on fresh paint.
- Use a small roller for flatter finish on tile faces and a brush only where needed.
- If the bathroom has poor ventilation, improve extraction before painting to help both application and durability.
Safety notes
- Ventilate the room well during cleaning, sanding, priming and painting.
- Wear gloves and eye protection when using cleaners, mould treatment and coatings.
- Do not mix cleaning chemicals unless the manufacturer specifically says it is safe.
- Take care on wet or dusty bathroom floors to avoid slips.
- Follow the product safety data and label instructions for storage, use and disposal.
Legal & regulatory notes
If you are renting, get the landlord's permission before painting tiles. In shared or multi-occupancy buildings, major ventilation or moisture problems may need to be reported rather than simply painted over.
What this guide does not cover: This guide covers repainting existing bathroom tiles in general terms. It does not replace the instructions for a specific primer or paint system, and it does not cover full retiling, waterproofing repairs, or substrate remediation.
Cost considerations
Painting tiles usually costs less upfront than retiling, but durability varies by location and product. The true cost is strongly affected by prep materials, primer compatibility, and whether the area needs repeat work sooner than a full replacement would.

Can you paint tiles inside a shower?+
Sometimes, but it is a higher-risk use and not every product is suitable for constant water exposure. Check the manufacturer guidance for shower enclosures specifically; if it is not clearly approved, assume it is better for splash zones rather than continuously wet areas.
Do I need to sand glossy tiles first?+
Usually yes, unless the manufacturer of a specific system says otherwise. Glossy glazed tiles are hard for coatings to grip, so deglossing is one of the most important preparation steps.
Can I paint over grout as well as the tiles?+
Yes, most tile-paint refreshes cover both tile and grout together. The grout must be sound, clean and dry; badly cracked or missing grout should be repaired first.
How long will painted bathroom tiles last?+
It varies with the product, the quality of preparation, ventilation, and where the tiles are located. Wall tiles in lower-wear splash areas generally last better than floors and constantly wet zones. Use the manufacturer guidance for expected performance and maintenance.
Can I use normal emulsion or wall paint on tiles?+
No. Standard wall paint is not designed to bond reliably to glazed tile or cope with bathroom moisture and cleaning. Use a coating system intended for tiles or for the exact surface and conditions.
The basic preparation and painting method changes slowly, but product compatibility and manufacturer instructions vary and should always be checked on the current label or website.
