The bathroom guide.

Everything that goes into a bathroom, from where the drain sits to which side of the mirror the light belongs on. Read it before you speak to anyone, including us.

01Layout

Start here. Everything else follows from where the wet zone goes.

A bathroom is decided by drainage. Moving the soil stack is expensive and sometimes prohibited outright in a Dubai tower, so the layout usually has to work around where the waste already is.

Walk-in shower
Glass panel, open entry, drained floor. The default for a modern apartment bathroom.
Tub and shower
Both, if the room can take it. Needs roughly 2.4m of wall.
Wet room
No tray, no threshold. The whole floor falls to one drain.
Double vanity
Two basins on one run. Wants at least 1.8m of wall.
Jack and Jill
One bathroom, two doors, shared between bedrooms.

02Waterproofing

The layer you never see and cannot skip.

This is the most commonly skipped step in a cheap renovation and the cause of most leak damage in Dubai apartments. Tiles and grout are not waterproof. The membrane underneath is.

01
Strip back to substrate
old tile and adhesive come off entirely, no tiling over tile
02
Level and prime
the screed is corrected before anything waterproof is applied
03
Liquid membrane, two coats
walls to 1.8m in the shower zone, the full floor everywhere
04
Corners and penetrations taped
joints and pipe entries are where leaks actually start
05
Flood test before tiling
the floor is filled and left. This is the step cheap jobs skip

03Flooring

It has to survive standing water, not just spills.

Anything going on a bathroom floor needs a low slip rating when wet. Check the building rules too: some Dubai towers require acoustic underlay under hard flooring.

Porcelain or ceramic tile sample
Porcelain or ceramic tile
Durable, water resistant, available matte, polished or textured. The default.
Natural stone sample
Natural stone
Marble, granite or slate. Luxurious and timeless, and it needs sealing.
Microcement sample
Microcement
Seamless and minimal, no grout lines at all. Ideal in a wet room.
Wood-look tile sample
Wood-look tile
The warmth of timber with none of the water risk.
Heated floor sample
Heated floor
Electric mat under the tile. Wire it in before anything is laid.

04Wall finishes

Where most of the surface area is.

Full-height tiling in the wet zone is non-negotiable. Beyond that it's a choice between tile, seamless finishes and paint — and the labour gap between them is larger than the material gap.

Large-format porcelain
Few joints, fast to lay, calm surface.
Mosaic
Sheets on mesh. Handles curves and niches other tiles cannot.
Natural stone slab
Marble or granite, continuous. The most expensive and the quietest.
Subway tile
Running bond. Cheap, timeless, forgiving of an uneven wall.
Microcement
Seamless, no grout at all. Needs a skilled applicator or it cracks.
Waterproof paint
Satin or gloss. The cost-effective answer for a guest WC.
Accent wall
One wall in something louder. Contains the cost and the risk.

05Showers

The part of the room that gets used every day.

Frameless glass and a level entry read as expensive but cost little more than the alternatives. What costs money is the ceiling void a rainfall head needs, and the falls in the floor a wet room needs.

Frameless
10mm glass, no metal frame. Visually disappears.
Walk-in
A single fixed panel, open on one side. Nothing to step over.
Rainfall
Ceiling-mounted head. Needs a false ceiling to hide the pipework.
Dual system
Fixed head plus handheld. The practical choice for a shared bathroom.
Shower bench
Built-in seat, tiled to match. Worth it if anyone will ever need to sit.
Tiled niche
Recessed shelf inside the wall. Decide before the blockwork goes up.

06Baths

Worth having, if the room can genuinely take one.

A freestanding bathtub needs clearance on all sides and a floor that can carry it filled. In a Dubai apartment, an alcove tub is usually the honest answer.

Freestanding
A statement, and it needs clearance on every side.
Alcove
Three walls, one open side. The space-efficient default.
Drop-in
Set into a built platform. Tiled surround, tailored look, more build.
Soaking
Deeper than standard for full immersion. Check the floor loading.
Whirlpool
Jets and a pump. Needs an access panel and a power supply.

07Vanities and storage

Storage is what a bathroom renovation usually gains.

Style, finish and top are three separate choices. A floating vanity in gloss white and one in oak with a stone top are the same unit with entirely different results.

Styles
Floating
Fixed to the wall, floor clear underneath. Makes a small room read larger.
Wall to wall
Runs the full width. Maximum worktop and storage.
Freestanding
On legs, movable. Traditional, and easier to replace later.
Double
Two basins. Needs 1.8m minimum or they crowd each other.
Open shelf
Towels on show. Light and airy, unforgiving of clutter.
Finishes
Matte
No sheen, hides splashes.
Gloss
Bounces light in a windowless room.
Woodgrain
Warmth against hard tile.
Stone top
Quartz or granite over any carcass.

08Toilets and bidets

Small item, large effect on how the room reads.

A wall-hung pan needs a concealed frame built into the wall, which costs more and takes space, and gives you a clear floor to mop. Decide before the blockwork.

Toilets
Wall mounted
Cistern hidden in the wall, pan floating. Easiest floor to clean.
Back to wall
Cistern concealed behind a panel, pan on the floor. No wall works needed.
One piece
Cistern and pan moulded together. No seam to scrub.
Smart toilet
Integrated bidet, heated seat, sensors. Needs a socket behind it.
Toilet features worth asking for
01
Soft-close lid
stops the slam, and the hinge is what fails first on cheap pans
02
Rimless bowl
no hidden rim channel, which is where limescale and bacteria collect
03
Dual flush
two button sizes. Standard now, worth confirming it is fitted
04
Deodorising and UV cleaning
smart models only, and a genuine luxury rather than a need
Bidet options
01
Electronic bidet seat
fits a standard pan, needs a socket nearby
02
Integrated bidet toilet
one unit, cleanest look, most expensive
03
Handheld sprayer
simple, cheap, and what most Dubai homes already use
04
Wall-mounted bidet unit
a separate fixture, needs its own drainage

09Fixtures and hardware

Finish first, then the pieces.

Pick one metal finish and hold it across taps, shower, hinges, towel rails and hooks. Mixed metals almost never look deliberate in a room this small.

Finishes
Matte black
Bold and current. Shows limescale in hard water, and Dubai water is hard.
Brushed nickel
Soft, subtle, forgiving of fingerprints. The safest choice.
Polished chrome
Timeless and cheapest to replace. Every brand makes it.
Brushed brass
Warm and upscale. Check the finish is PVD or it will wear.
Gunmetal
Dark and unusual. Fewer matching accessories available.
Rose gold
Distinctive, and harder to pair with tile than it looks.
Essential hardware
01
Basin and wall-mounted taps
wall-mounted frees the countertop but must be set before tiling
02
Shower mixers and diverters
a diverter is what lets one valve feed two heads
03
Handheld sprayers and rain heads
the handheld is what actually cleans the enclosure
04
Towel bars, hooks and paper holders
fix into blockwork, not plasterboard
05
Robe hooks and grab bars
a grab bar costs little now and a great deal to retrofit
Worth considering
01
Sensor taps
no touch, no smears, and no way to leave it running
02
Thermostatic controls
the shower holds temperature when a tap runs elsewhere
03
Water-saving aerators
lower flow with no perceptible drop in pressure
04
Integrated LED lighting
in niches, under vanities, behind mirrors

10Lighting and mirrors

The difference between a bathroom and a good one.

One ceiling light behind you puts your face in shadow at the mirror, which is the one thing a bathroom mirror exists for. Light the face from the front or the sides.

Lighting
01
Vanity lighting
either side of the mirror, not above it, or you light your own shadow
02
Recessed ceiling lights
general light. Keep them out of the shower zone unless IP rated
03
LED strip
under the vanity or behind the mirror. Glow, not glare
04
Statement fixture
a pendant beside a freestanding tub, if the ceiling height allows
05
Dimmer control
a bathroom used at 7am and at 11pm needs two different brightnesses
Mirrors
Backlit
LED behind the glass. Even light on the face, no shadow under the eyes.
Frameless
Polished edge, nothing around it. Cheapest and quietest.
Round
Softens a room full of straight tile lines.
Mirrored cabinet
Storage behind the glass. The best use of a shallow wall.
Smart mirror
Anti-fog, presets, a display. More to go wrong.
Questions

What homeowners ask first.

How long does a bathroom renovation take in Dubai?

A standard apartment bathroom takes 5–10 working days. Larger bathrooms, or any with layout changes, take 2–3 weeks. The timeline is confirmed before work starts.

Can I use my other bathrooms during the renovation?

Yes. We renovate one bathroom at a time, so your other facilities stay usable throughout.

Do you handle waterproofing?

Yes, and we treat it as non-negotiable. Every bathroom gets proper membrane waterproofing before tiling. It is the most commonly skipped step in cheap renovations and the cause of most leak damage in Dubai apartments.

Can you match the style of my existing apartment?

Yes. We work to your aesthetic, whether that is modern minimalist, warm Japandi or classic marble, and can advise on tile and fixture combinations if you want guidance.

Do you handle permits if required?

For structural changes such as moving walls or relocating plumbing stacks, jointly owned buildings may require permission from building management. We advise on this at consultation.
