How to paint a bathroom floor (tiles) with no building work: step-by-step guide
The floor takes more punishment than any other part of the bathroom: wet feet, cleaning products, years of use… and one day you realise those tiles bore you (or downright horrify you). The good news: there is no need to rip them up. Painting the bathroom floor is the fastest, cheapest way to renovate it with no building work, no rubble and no week without a bathroom.
The condition: use a dedicated floor paint — wall tile paint will not do — and respect some very specific drying times. In this guide we tell you exactly how to do it, what it costs and what to expect. No fluff.
Can you paint a bathroom floor?
Yes, you can paint bathroom floor tiles, and the result lasts for years if done properly. You only need three things: firmly fixed tiles (no loose pieces), a paint formulated for FLOORS — one that withstands footfall and scuffs, not just humidity — and respect for the drying times before walking on it and wetting it. That is all. No sanding, no primer, no previous experience.
Which paint to use for a bathroom floor (and which to avoid)
Here is the most common mistake: using a wall tile paint on the floor. Wall tile paints — like our Smartcover Tiles — are terrific on vertical surfaces, but they are not made to take daily footsteps. For the floor you need a proper floor paint.
We use Smartcover Floor: a one-component water-based epoxy paint (epoxy-acrylic copolymers) originally designed for garage floors — it withstands car wheels and typical garage grease — so in a bathroom it is more than up to the job. What makes it ideal for a weekend DIY:
- No primer and ready to use: no mixing components or adding colour; just stir gently and paint.
- Straight onto the tile: clean, degrease and go. No need to sand the glaze.
- Uniform matt/satin finish, in 8 colours.
- 100% compatible with underfloor heating, and also suitable outdoors (it is aliphatic: it does not yellow).
- What it costs: the 4.5 L bucket costs €114.17 and covers 22.5–27 m² with two coats (~€4–5/m²). For a 4–6 m² bathroom floor most of the bucket will be left over: keep it for future touch-ups or another room (kitchen, terrace, garage).

How to paint bathroom floor tiles step by step
Materials: Smartcover Floor, a roller (plus a brush for edges), masking tape, a degreasing cleaner and, optionally, Smart Jointer if you want a completely smooth surface.
1. Clean and degrease thoroughly
This is THE key step: the adhesion is in the formula, but it needs a clean surface. Wash with soapy water, remove limescale and grease, and let it dry. There is no need to sand the tile glaze.
2. Decide what to do with the grout lines
Two options, both valid: keep the tile texture (the grout lines get painted and blend in, with a very natural result) or, if you prefer a completely smooth surface that is even easier to clean, re-grout first with Smart Jointer.
3. Protect and stir
Masking tape on skirting boards, sanitaryware and wall junctions. Open the bucket and stir gently: it is one-component and comes with the colour ready-mixed.
4. First coat, wait, second coat
Apply a thin first coat with the roller (brush for edges and corners). Let it dry for 3–4 hours depending on temperature: 3 is enough in summer; in winter, better 4. Apply the second coat. And that is it: two coats are necessary and sufficient, whatever the original colour.
5. Respect the times before using the bathroom
This is where the result is won or lost, so here it is in plain terms:
| When | What you can do |
|---|---|
| At 24 hours | Walk on it carefully (no dragging furniture, no knocks) |
| At 72 hours | Fully hardened: normal use of the bathroom… dry |
| At 7 days | You can now wet the floor: shower and mop without worry |
Honest tip: if you only have one bathroom with a shower, plan your week (the basin and WC are back in careful use at 24–72 hours; the shower, at 7 days). It is the only real “price” of this renovation.
Colours and ideas for a painted bathroom floor
Of Smartcover Floor's 8 colours, White and Grey are the most versatile base for a bathroom: light, spaciousness, and they go with everything. The bold tones (Blue, Green, Red, Orange, Violet, Yellow) work brilliantly as accents: a stripe, a painted “rug” under the basin or to zone the shower area.
And for the full transformation: walls with a tile paint (Tiles) + floor with Floor is a combination that renews the whole bathroom without a single day of building work.
Before and after painting a bathroom floor
Two real examples of what painting the floor (and the walls while you are at it) does to a bathroom:
A painted floor to play with contrast: dark floor tiles and light walls — elegance without building work.
Floor and walls, the full change: two surfaces, two complementary colours, one unrecognisable bathroom.
How long a painted bathroom floor lasts (and how to care for it)
Durability is 5 to 10 years, depending on use and maintenance. And when the time comes to freshen it up, the repair is cheap and simple: light sanding with 180-200 grit and one coat of the same colour (~€2/m² in materials). Want to change colour? Then two coats, essential.
Day to day: neutral cleaners (also better for your health) and avoid bleach, ammonia and metal scourers — no decorative coating tolerates them well.
Frequently asked questions
Is painting a bathroom floor worth it?
If the tiles are firmly fixed and what you want is a cosmetic change with no building work, yes: for ~€4–5/m² in materials and one weekend you get a new floor that lasts years. It is not worth it if there are loose tiles or damp underneath: fix that first.
Is a painted floor slippery?
The finish is matt/satin and it is not strictly non-slip, but you will not go sliding just because you step on it with wet feet out of the shower: treat it like any ceramic floor — caution with lots of water and, if you like, a mat by the shower exit.
How much does it cost to paint a bathroom floor?
Materials come to ~€4–5/m² with two coats. The 4.5 L bucket (€114.17) covers 22.5–27 m², so in a bathroom you will have plenty left for years of touch-ups. Compare that with ripping up the floor and re-tiling: building work, rubble, days without a bathroom and considerably more money.
Does it work with underfloor heating?
Yes, it is 100% compatible with underfloor heating.
Can you paint the shower floor?
Yes, Smartcover Floor is also suitable for the shower floor. The only condition is the usual one: respect the 7 days without water after painting — no shortcuts with the shower.
What if I want to paint the wall tiles instead?
Then you need a different paint (for walls) and a different guide: how to paint bathroom tiles: ideas and steps.
