Microcement Bathrooms in Dubai

A microcement bathroom is a bathroom where the floor, the walls and the shower are one seamless, grout-free microcement surface laid over a waterproofing (tanking) membrane and finished with an immersion-grade sealer. A microcement bathroom in Dubai starts from AED 350/m², the wet-zone rate, supply and install — it applies to the whole room because the membrane and sealer run through all of it (a guest toilet with no shower can use the wall and floor rates, from AED 220/m² and AED 250/m²) — and takes about six to seven working days including cure and sealing. It usually goes straight over sound existing tiling, with no demolition. The microcement gives the look; the membrane and the sealer do the waterproofing. For floors, walls and stairs in the rest of the home, see microcement in Dubai, which also covers how our microcement installation in Dubai runs room by room.

A bathroom with no joints to fail

Tiles don’t usually fail — the grout between them does. Every metre of joint is a seam where water works in, where soap scum settles, and where black mould eventually shows. A microcement bathroom removes the seams entirely: walls, floor and shower become one continuous, sealed mineral surface.

That’s why it has become the quiet upgrade of choice in Dubai renovations. It goes over the tiles that are already there — no demolition, no rubble, no fortnight of noise — and leaves a calm, monolithic room that wipes clean and stays looking new.

Microcement shower: walk-in, wet room, niche

A microcement shower, walk-in or wet room, starts from AED 350/m², about AED 33 per square foot, supply and install, with the tanking membrane and the immersion-grade sealer inside that rate. The same rate covers the shower floor, the shower walls and a niche recessed into the wall, because one membrane and one sealer run through all of them. A walk-in shower has the floor laid to falls toward a linear or point drain, with a fine anti-slip texture and no tray or threshold. A wet room extends the same build-up across the whole floor, so the room has no step at all. A niche is formed in the wall build-up, tanked like the rest and coated in the same finish, so storage is part of the surface rather than tiled into it. Quotes follow a site visit, where the drain position and substrate decide the detail.

Microcement bathroom problems — what goes wrong when it is done badly

Most microcement bathroom problems are installation problems wearing a material’s name. The ones we see most often: water getting behind the coating because no tanking membrane was laid (the coating is water-resistant, not waterproof — the membrane is the waterproofing); hairline cracks at the wall-floor junction and around the shower tray where the substrate moved and no mesh was embedded; a dull, blotchy shower floor where a dry-area sealer was used instead of an immersion-grade one and soap and hard water have worked into it; and slippery floors where a smooth finish went into a wet zone with no anti-slip texture. None of these is intrinsic to microcement. All of them are avoided by tanking, mesh, the right sealer and a crew that does wet rooms weekly.

Microtopping bathroom ideas: floor, walls, shower and ceiling in one surface

The idea people come to us with most is the wet-room look: the shower floor, the bathroom floor and every wall in the same tone, with no threshold and no change of material. Variations that work well in Dubai homes: a single dark feature wall behind a freestanding bath with pale floor and walls; the ceiling in the same tone, so the room reads as one shell; and a niche recessed into the shower wall, coated in the same finish, so storage is built into the surface rather than tiled into it. The vanity and basin themselves stay stone or ceramic — we apply microcement to floors, walls and ceilings only. The microtopping bathroom floor gets a fine anti-slip texture; walls stay smooth. Colour choices are covered in microcement colours, and how a microcement wall in a living room or kitchen compares, in finish and rate, is in our microcement wall guide.

How an RBS bathroom job runs, day by day

A bathroom follows the same coat-by-coat sequence as any microcement job, but tanking comes first and runs through the whole room, not just the shower tray — that’s the one thing a dry-room schedule does not have to plan around:

Day	What happens
Site visit	Existing tiles or substrate checked, moisture reading taken, shower tray and drain position confirmed, sample approved
1	Room protected; substrate degreased. Full tanking membrane applied to the floor and the shower walls up to 1.8–2 m, with falls built into the floor toward the drain
1–2	Reinforcing mesh embedded at the wall-floor junction, the shower tray edge and any door threshold — the movement points that crack a bathroom if skipped
2–3	Base coat one across walls, floor and shower, sanded once cured
3–4	Base coat two — the structural layer, laid only once the tanking beneath has fully cured
4–5	Finish coat one (colour goes in), then finish coat two — smooth on the walls, a fine anti-slip texture specified into the shower and pan floor
5–6	Sealing — two or more coats of an immersion-grade sealer, cured before any water touches the room
6–7	Handover — walkable, but we tell every client to keep the shower dry until the sealer reaches full cure hardness

Every extra day here is the membrane and sealer curing, not labour — a bathroom quoted at three or four days flat has skipped a cure window somewhere in that table.

A worked example: a 25 m² family bathroom

Real numbers, from the rates published on this page, walked through on the size we quote most often — a family bathroom of roughly 25 m² (floor, walls and a walk-in shower) going in over sound existing tiles:

• Why the whole room prices at the wet-zone rate. The tanking membrane and immersion-grade sealer run through the entire bathroom, not just the shower tray, so the AED 350/m² wet-zone rate applies to the full area rather than mixing rates by wall. 25 m² × AED 350/m² = AED 8,750, which is why this page and our microcement cost guide both quote a 25 m² bathroom done entirely at the wet-zone rate “from around AED 8,750” — the same figure, not a new one.
• Build-up: full tanking membrane to the floor and shower walls, mesh at the shower tray edge and the door threshold, two base coats, two colour finish coats, an immersion-grade sealer, and a fine anti-slip texture specified into the shower and pan floor.
• Time: six to seven working days including cure and seal, matching the table above.
• What would move the number: a freestanding bath needing its own tanked plinth, a bespoke colour requiring its own sample and batch, or extending the same finish into an adjoining powder room — each is priced at the site visit, not guessed here.

Microcement vs tiles, PVC wet-wall panels and waterproof paint in a Dubai bathroom

	Microcement	Tiles	PVC / acrylic wet-wall panels	Waterproof paint over tanking
Joints	None	Grout lines throughout	Vertical seams between panels	None, but it telegraphs every flaw in what’s underneath
Goes over existing tiles	Yes, bonds straight over a sound substrate	Only with demolition or a height allowance	Usually needs the surface built out flat first	Yes, but old grout lines read through the coat
Where the waterproofing lives	A full tanking membrane + immersion-grade sealer, engineered as one system	A membrane under the tile bed — the tile itself isn’t the waterproofing	Largely self-sealing at the panel joints	The paint film itself is the wear layer — thin, and the first thing to fail
Feel underfoot / on the wall	Smooth or fine-textured mineral trowel finish	Cold, hard, grout texture	Slightly flexible, visible seam up close	Whatever texture is already beneath it
Starting price in Dubai	From AED 350/m² (wet zones); walls from AED 220/m², floors from AED 250/m²	Quote-only — not a system we install	Quote-only — not a system we install	Quote-only — not a system we install
Best fit	A seamless, grout-free bathroom that goes over what’s already there	New-build bathrooms where grout lines aren’t a concern	A fast panel-over-tile refresh, e.g. a rental	Never as the only waterproofing in a shower — paint alone is not tanking

We don’t install tiles, PVC wet-wall panels or paint-only waterproofing, so those price rows are left blank rather than guessed. The honest trade-offs against tiling specifically are in microcement vs tiles.

Microcement bathroom over existing tiles, and when we would not do it

A microcement bathroom can go over existing tiles when the tiles are sound, firmly bonded and the room has no moisture problem behind them; the joints are filled and keyed first, so the grout lines do not read through the finish. We tap-test the tiles at the site visit and will say so plainly if they are hollow or the wall is damp, because microcement over a failing substrate fails with it. In that case the honest answer is to repair or strip that area first, and the price moves accordingly.

Two other cases where we would tell you to think again: a bath that is filled and left standing daily against an untanked timber or board wall, and a rental where the landlord wants the cheapest possible refresh. Neither is a good match for a tanked, sealed, hand-finished system.

Caring for a microcement bathroom in a Dubai home

Cleaning is simple: a pH-neutral cleaner and a soft cloth or mop, wiped down after use in the shower. Avoid acidic descaler and abrasive pads, which dull the sealer; hard Dubai water leaves limescale on any surface, and here it is removed with a neutral cleaner and a squeegee habit rather than acid. The sealer in a hard-used shower is the part that ages, and it can be renewed without redoing the microcement beneath it. The full routine is in our microcement cleaning guide.

The waterproofing is the whole job

The finish gets the attention, but the engineering underneath is what matters. In every RBS wet zone we install a full tanking membrane, detail the falls so water reaches the drain, and seal the microcement with an immersion-grade finish built for constant wetting. For shower floors we can specify a fine anti-slip texture, so grip is designed in from the start.

Applied this way — by our own trained crews, in the correct layers and cure windows — a microcement bathroom outlasts and outperforms the grouted tile it replaces. Pick your colour from our chart, approve a physical sample, and we’ll build it properly.
