A guest or family bathroom refitted to a good standard typically costs AED 25,000 to 55,000. A master ensuite with large-format tiling, a walk-in shower and quality brassware usually falls between AED 55,000 and 120,000. A high-specification bathroom with book-matched stone, a freestanding bath and a steam shower commonly runs AED 120,000 to 250,000 and above.
Why two bathroom quotes differ by forty per cent
Two quotations for the same bathroom can differ enormously, and it is rarely because one contractor is greedy. It is because they have priced different jobs.
The differences hide in four places. Whether the tanking is a proper membrane system or a coat of paint-on sealer. Whether the screed is laid to a genuine fall or simply flat. Whether the shower glass is made to measure or an off-the-shelf enclosure. And whether the extract actually reaches an external wall or vents into the ceiling void.
All four are invisible in the finished room. All four determine whether it is still a good bathroom in five years.
Tanking is the item that matters
Tanking is the waterproof membrane applied to floors and wet walls before tiling. Tiles and grout are not waterproof. Without a properly lapped and tested membrane, water tracks into the screed and eventually into the ceiling below.
This is how an AED 40,000 bathroom becomes an AED 120,000 insurance claim, and it is the first thing cut when a price is being squeezed because nobody can see it afterwards.
Every Benstead bathroom is tanked and flood-tested for twenty-four hours before tiling, and photographed as part of the handover file.
What moving things costs
Relocating sanitaryware means new soil and waste runs, and waste needs a consistent fall to reach the existing stack. In a villa this usually costs AED 12,000 to 35,000 extra. In an apartment the slab cannot be cut, so relocation often means building up the floor or forming a step — workable, but it has to be designed rather than discovered.
Where the money actually goes
On specification, our guide to sanitaryware and brassware for Dubai water covers which premium is worth paying. Not where people expect. The visible items — sanitaryware, brassware, the vanity — are rarely the largest share. Labour, tiling, waterproofing and the making good around them usually are, and large-format tiles are considerably more expensive to lay than small ones because the substrate has to be genuinely flat.
The single biggest variable is whether the drainage moves. Keeping the WC, shower and basin in their existing positions avoids new soil and waste runs, avoids a permit, and takes weeks out of the programme.
What the cheap quotation omits
The tanking, and the testing of it. A quotation that does not name the waterproofing system and does not include a water test before tiling is not a comparable price — it is the same room with the one thing that matters left out.
Also commonly missing: making good to the ceiling below after drainage work, the electrical alterations for lighting and an extract that actually extracts, and the substrate preparation that large-format tiling requires.
Why ventilation belongs in the budget
An extract fan that moves too little air for the room volume produces mould on new paint within a year in this climate. It is a small item that undoes an expensive room, and fan sizing plus duct run length is what determines whether it works.
It is also the single most common complaint we are called to look at in a bathroom that was renovated two years earlier by someone else.
How we arrive at a figure
We do not price from a floor area and a rate. We measure the work and produce a bill of quantities — every element listed, quantified and rated — so that what you are agreeing to is legible rather than implied.
That is also what makes two quotations comparable. A single lump sum tells you nothing about what has been included; a measured breakdown tells you exactly where the difference between two prices sits. For an indicative range before any of that, the cost calculator takes about a minute.
| Specification | What it includes | Indicative range |
|---|---|---|
| Guest / family | Strip-out, tanking, porcelain tiling, mid-range sanitaryware, vanity | AED 25k – 55k |
| Master ensuite | Large-format tiling, frameless walk-in shower, quality brassware, bespoke vanity | AED 55k – 120k |
| High specification | Book-matched stone, freestanding bath, steam shower, underfloor heating | AED 120k – 250k+ |
| Relocating drainage | New soil and waste runs, floor build-up or step, permit where required | + AED 12k – 35k |
If the bathrooms are part of a wider refurbishment, the renovation cost calculator will give you an indicative all-in range for the whole property.
Related Questions
How long does a bathroom take?
Three to five weeks on site. Strip-out, first fix, waterproofing, a twenty-four hour flood test, screed to falls, tiling, second fix, then glass and sealing.
The waterproofing and its test cannot be compressed. Any contractor offering a complete bathroom in ten days is skipping a step you will pay for later.
Can I just retile over the existing tiles?
Possible where the existing surface is sound and well bonded — but rarely the right call in a bathroom.
Tiling over means you never see the tanking underneath. If that membrane has failed, you have buried the problem more deeply and more expensively.
How much does a bathroom renovation cost in Dubai?
It varies with specification and, most of all, with whether the drainage moves. A guest or family bathroom replaced in its existing layout sits well below a master ensuite with large-format stone, a walk-in shower and bespoke joinery. Relocating the WC or shower adds both cost and several weeks for the permit.
Why is moving the toilet so expensive?
Because it means new soil and waste runs working on the falls available within the floor build-up, which in an apartment is often only about 60mm. It also triggers an authority permit, consultant drawings, and in many buildings the owners association's consent — some prohibit it outright.
Should the waterproofing be tested?
Yes, and you should have it written into the contract as a hold point. A proper test floods the tanked area, stands twenty-four hours and is checked in the room below before any tiling starts. If a contractor treats that as unusual, you have learned something useful about how they work.
Why are large tiles more expensive to lay?
Because they expose everything. A large-format tile cannot follow an uneven substrate the way a small one can, so the wall or floor has to be genuinely flat before tiling starts. That preparation is real labour and it is frequently absent from a cheap quotation that quotes the same rate regardless of format.
Can I just replace the sanitaryware?
Yes, and it is a legitimate way to improve a bathroom cheaply if the tiling and waterproofing are sound. What it does not do is address a tanking failure or a ventilation problem, so it is worth establishing the condition of both before deciding that the visible items are the whole job.
What ruins a bathroom renovation most often?
Ventilation, then waterproofing. An undersized extract leaves humidity on cold surfaces and produces mould on new paint within a year here. It is a small item that undermines an expensive room, and it is the complaint we are most often called to look at on someone else's work.
Does a new bathroom add value?
Alongside the kitchen it is the room that most affects a buyer's or tenant's decision, and a tired bathroom reliably costs more at sale than replacing it would have. Whether a specific specification returns its cost depends on the property — a very high specification in a mid-market apartment rarely does.
What is the cheapest way to improve a bathroom?
Keep the drainage where it is, replace sanitaryware and brassware, retile, and spend the saving on the things that fail — the waterproofing and the extract. Moving the layout is what makes a bathroom expensive, and it is often the change that adds least.
