Bathroom Tiles in Dubai: How to Choose Them — or Skip Them

For a bathroom in Dubai, choose porcelain tiles for the floor and the shower, with a slip rating made for wet bare feet; ceramic tiles are fine on the dry walls. But the tile is the smaller decision. What makes a tiled bathroom last in the UAE is the waterproofing membrane behind the tiles, a floor that falls properly to the drain, grout that does not soak up soap (epoxy grout in the shower) and silicone joints at every corner. Get those right and almost any decent tile will do. If what you are really tired of is grout, there is a second route: a seamless bathroom with no tiles at all, in microcement or tadelakt — this guide covers both honestly.

A word on who is writing this. RBS applies seamless surfaces — microcement, lime plasters such as tadelakt, resin bound stone. We do not sell, supply or lay tiles. So where this page says tiles are the right answer for your bathroom, that advice costs us the job, and a good tile showroom and a careful tiler are the people to call.

This page is about tiles for the bathroom specifically. For the general difference between the two tile materials on any floor, see ceramic vs porcelain tiles in Dubai; for the head-to-head between a tiled and a seamless bathroom, see microcement vs tiles.

Which tiles are best for a bathroom in Dubai?

Porcelain on the floor and inside the shower; ceramic or porcelain on the walls outside it. A bathroom floor is wet, walked on barefoot and cleaned with everything from bleach to limescale remover. Porcelain absorbs very little water (0.5% of its weight or less, by the tile standards) and resists stains and chips better than ceramic, so it is the safer floor tile. Walls outside the shower take no foot traffic, so a glazed ceramic wall tile is a perfectly good, lighter and cheaper choice there.

Three things matter more than the brand or the showroom label:

• Slip rating on the floor. Glossy polished porcelain looks beautiful in a showroom and is treacherous under a wet foot. Ask for a matt or textured floor tile with a wet barefoot slip rating (in the common German classes, B or C for shower floors) or an equivalent wet pendulum result. A ramp rating such as R10 or R11 is measured with shoes on, so it is not the right number for a shower.
• Rectified edges if you want narrow grout lines. Rectified tiles have ground edges and can be laid with joints around 2 mm; non-rectified tiles need wider joints.
• The tile’s own data sheet. It names the class, the water absorption and the slip test. If a shop cannot show you one, choose a tile that has one.

Floor, wall and shower: which tile goes where

Zone	What works	What to avoid	The detail that matters
Bathroom floor	Matt or textured porcelain	Polished or glossy tiles; soft ceramic floor tiles with a low wear rating	Wet barefoot slip rating; fall to the drain if there is a floor drain
Shower floor	Small porcelain or mosaic tiles, or a large tile with a linear drain	Big flat tiles on a floor that must slope four ways to a centre drain	Falls to the drain, membrane underneath, epoxy grout
Shower walls	Porcelain or a good glazed ceramic	Natural stone without a sealer plan; porous unglazed tiles	Membrane behind the tiles up to full shower height
Walls outside the shower	Glazed ceramic or porcelain	Nothing special — this is the easy zone	Silicone at the floor junction, not grout
Vanity splashback	Ceramic, porcelain or a slab	Very rough textures that trap toothpaste and soap	Easy-to-clean surface
Bath surround and niche	Same tile as the walls, or a single slab shelf	Tiny mosaics with many grout lines behind the taps	A slight fall on the niche shelf so water drains off

Large tiles or mosaics in the shower?

Large tiles mean fewer grout lines; small tiles follow the slope. A floor that drains to a centre point has to fall in four directions, and a large flat tile cannot bend to that shape — it ends up with lips at its edges or needs awkward diagonal cuts. That is why traditional shower floors use mosaics or small tiles. If you want large tiles on the shower floor too, plan a linear (channel) drain at one wall: the floor then falls in one direction, and big tiles lie flat on it.

On the walls, large-format porcelain (60 × 120 cm and up) gives the calm, almost seamless look many people want. The trade-off: big tiles need a very flat wall, full adhesive coverage on the floor or wall and on the back of the tile, levelling clips and a tiler who has laid them before. On a wavy wall they show every bump as a raised edge.

Matt or glossy bathroom tiles?

Matt on the floor, either on the walls. Gloss shows water spots and limescale from hard tap water; a rough matt texture can hold soap scum. Satin or soft-matt is the practical middle, and mid tones forgive both limescale and grout discolouring.

Waterproofing behind bathroom tiles: the part you never see

Tiles and grout are not waterproof — the membrane behind them is. Cement grout is porous, and water that gets through it reaches the wall and the floor slab. In an apartment that means a leak in the ceiling of the flat below; in a villa it means damp walls and a smell that never goes. A proper tiled shower has a waterproofing (tanking) membrane on the floor and on the shower walls, carried up well above the shower head, with reinforcing tape at every corner and around the drain, and a water test before the tiles go on. Our waterproofing guide explains what each wet area needs.

Ask your tiler which membrane, how high on the walls, and whether they will flood-test before tiling. A quote without the membrane is not a cheaper bathroom — it is a problem built in.

Grout and silicone: why bathroom tiles look old so fast in the UAE

Grout darkens first, and silicone goes black next. Warm, humid bathrooms with the extract fan off are perfect for mould, and cement grout soaks up soap, body oils and limescale. Three things help:

• Epoxy grout in the shower. It costs more and is harder to lay neatly, but it does not absorb water or soap the way cement grout does, so it stays its colour far longer.
• Silicone, not grout, at every corner — where walls meet the floor, around the shower tray, at the bath edge. Those are movement joints, and grout there cracks. Silicone is a maintenance item: plan to cut it out and redo it when it discolours.
• Ventilation. Run the extract fan during the shower and for a while after; squeegee the walls. No tile survives a room that never dries.

When grout is already dark, see grout cleaning in the UAE for what cleaning, regrouting and colour sealing can and cannot fix.

Can you tile over old bathroom tiles?

Sometimes — if the old tiles are sound, firmly bonded and the extra thickness fits. Tile-on-tile adds roughly a centimetre with adhesive, which can upset door clearances, the floor drain level and the shower screen. The old tiles must not be hollow (tap them: a dull, empty sound is a warning), and the surface needs a primer made for tiling over tiles. Hollow or cracked tiles must come off first, and if the shower leaks now, its membrane must be fixed — tiling over a leak just hides it.

There is a thinner way to cover old bathroom tiles: a seamless coating at about 3 mm that goes straight over sound tiles, with the grout lines filled first. Details in microcement over tiles.

How much do bathroom tiles cost in Dubai?

We cannot give you an honest tile price, because we do not supply or lay tiles. A tiled bathroom’s cost is driven by the tile itself (porcelain or ceramic, size, finish), adhesive and grout (epoxy grout costs more), removal of the old tiles and debris, levelling, the waterproofing membrane, the drain, and the tiler’s labour — large-format tiles take longer to lay. Get two or three written quotes that list each of those items, and compare like with like: a low quote without the membrane and the removal is not a low price.

What we can price is the seamless route. A microcement bathroom — floor, walls and shower as one surface over a tanking membrane, finished with an immersion-grade sealer — starts from AED 350/m², the wet-zone rate. A bathroom with around 25 m² of floor and wall surface therefore starts from around AED 8,750 (25 × 350); the quote after the site visit can be higher if the walls or the floor need repair first. Microcement in dry rooms starts from AED 220/m² for walls and AED 250/m² for floors.

Bathroom tiles or no tiles at all?

Choose tiles for the toughest, most forgiving surface for the money; choose a seamless bathroom when grout is the thing you want gone. Porcelain shrugs off harsh cleaners and knocks, and a damaged tile can be swapped if you kept spares. A seamless bathroom gives you one continuous surface with no grout to darken — floor, walls and the shower in one tone — and microcement can go over sound old tiles with no demolition.

The two seamless options we apply:

• Microcement — a hand-trowelled mineral coating about 3 mm thick, laid over a tanking membrane with falls to the drain, a fine anti-slip texture on the shower floor and smooth walls. It is a finish for homes and normal-use rooms. It needs its sealer renewed every few years, and it takes about six to seven working days including curing.
• Tadelakt — burnished lime plaster, the traditional grout-free shower finish, soaped to repel water. It has a softer, hand-made look and is priced per project after a site visit. The side-by-side is in tadelakt vs microcement for a bathroom.

What a seamless bathroom is not: indestructible. A dropped heavy bottle can mark it, the sealer is a maintenance item, and the result depends on the crew far more than with tiles. If you want to clean with anything at all and never think about sealers, porcelain tiles are the honest answer.

Which one should you choose?

• A family bathroom you want to clean with anything and forget: matt porcelain on the floor and in the shower, epoxy grout in the shower, a full membrane behind it all.
• Walls outside the shower on a budget: glazed ceramic tiles.
• A walk-in shower with large tiles: a linear drain, so the floor falls one way and big tiles lie flat.
• No grout lines at all, one calm surface floor to ceiling: a microcement bathroom from AED 350/m², or tadelakt for a lime finish.
• Old tiles that are sound but dated, no demolition: a seamless coating over the existing tiles.
• Old tiles that are hollow, cracked or leaking: strip them, fix the membrane, then choose either route.
• Walls outside the shower in a richer finish: Venetian plaster in a bathroom works away from direct spray.

FAQ

What is the best tile for a bathroom floor in Dubai?

Matt or textured porcelain with a wet barefoot slip rating. Porcelain absorbs 0.5% of its weight in water or less and resists stains and chips; avoid polished or glossy tiles on the floor, because they are slippery when wet.

Are porcelain or ceramic tiles better for a bathroom?

Porcelain for the floor and inside the shower; glazed ceramic is fine and cheaper on the walls outside the shower. The membrane behind the tiles matters more than the choice between the two.

Are large tiles good for a small bathroom?

On the walls, yes — fewer grout lines make a small room look calmer and bigger. On a shower floor that drains to a centre point, large tiles do not follow the slope well; use small tiles there, or a linear drain so the floor falls in one direction.

Do bathroom tiles need waterproofing behind them?

Yes. Tiles and cement grout are not waterproof. A tanking membrane on the shower floor and walls, with taped corners and a flood test before tiling, is what keeps water out of the wall and the flat below.

How do I stop bathroom grout going black?

Use epoxy grout in the shower, silicone (not grout) at corners and junctions, and run the extract fan during and after showers. Dark cement grout can sometimes be cleaned or colour-sealed; when it is crumbling, it needs regrouting.

Can you have a bathroom without tiles in Dubai?

Yes. A microcement bathroom runs the floor, walls and shower as one sealed surface over a tanking membrane, starting from AED 350/m²; tadelakt does the same in lime and is priced per project after a site visit. Microcement can go over sound existing tiles; tadelakt needs the tiles removed and a mineral base first.

Does RBS supply or install bathroom tiles?

No. We do not sell, supply or lay tiles — for tiles, a tile showroom and a good tiler are the right call. We apply seamless bathroom finishes: microcement and tadelakt.
