Bathroom Renovation Cost in Dubai: What to Expect
Bathrooms are the most expensive room per square foot in any home, and the least forgiving if done badly. A leak behind a wall in year two costs far more than doing the waterproofing properly in week two. Here is what a bathroom renovation in Dubai actually costs, and what separates a good job from a cheap one.
Price ranges by scope
Bathroom pricing depends almost entirely on how far back you strip. Three broad levels:
- Cosmetic refresh — roughly AED 8,000 – 15,000. New sanitaryware, mixers, mirror, lighting and paint. Existing tiles and plumbing layout stay.
- Full rebuild, same layout — roughly AED 15,000 – 30,000. Strip to substrate, re-waterproof, new tiling, new sanitaryware and fittings, plumbing and electrical refreshed in place.
- Full rebuild, new layout — roughly AED 25,000 – 50,000+. Everything above, plus relocating drainage, water lines and power. Premium finishes, custom vanity or a walk-in shower push the upper end.
Waterproofing is the part you cannot see
This is where a cheap bathroom job shows itself — not immediately, but eighteen months later as a damp patch on the other side of the wall.
A proper wet-area build means the substrate is prepared and levelled, a waterproof membrane is applied across the floor and up the walls to the correct height in shower areas, corners and pipe penetrations are detailed, and the membrane is water-tested before a single tile goes down.
Skipping the water test saves a day. Fixing a leak later means demolishing finished tiling, in your bathroom and possibly your neighbour's ceiling.
Where the money goes
In a typical Dubai bathroom rebuild, the split is roughly:
- Demolition and debris removal — small share, but a fixed cost regardless of bathroom size
- Waterproofing and screed — modest cost, disproportionate importance
- Tiling — labour plus material; large-format tiles cost more to lay but look better
- Sanitaryware and mixers — the widest price range of anything in the room
- Plumbing and electrical — rises steeply if anything moves position
- Vanity and joinery — off-the-shelf versus made to measure is a large swing
Decisions that quietly add cost
Small specification choices have outsized cost effects. Worth knowing before you commit:
- Moving the WC — drainage falls are fixed by the building's stack. Relocating a WC is far more involved than moving a basin.
- Walk-in shower with a linear drain — needs a properly formed fall and careful waterproofing detailing.
- Concealed cisterns and wall-hung units — cleaner look, but needs framing and adds labour.
- Underfloor heating or heated mirrors — extra electrical circuits.
- Large-format or natural stone tiles — heavier, less forgiving, slower to lay, more wastage.
How long it takes
A cosmetic refresh takes 4 to 7 days. A full rebuild in the same layout usually runs 2 to 3 weeks. Changing the layout takes 3 to 4 weeks. Curing and water testing take real days that cannot be compressed — a contractor promising a full bathroom rebuild in five days is skipping something.

Can I retile over existing bathroom tiles?
It is technically possible, but not advisable in a wet area. Tiling over existing tiles means you cannot inspect or renew the waterproofing underneath, and it raises the floor level, which affects door clearances and drainage falls.
How long should bathroom waterproofing last?
A correctly applied and tested membrane should last the life of the finishes above it. Failures almost always come from poor detailing at corners and pipe penetrations, or from skipping the water test.
Do I need an NOC to renovate a bathroom?
Usually yes, especially where plumbing or electrical work is involved. Buildings and communities typically require approval before wet-area work begins.
