Where the money goes
What is the most expensive part of a bathroom renovation?
The layer you never see again: strip-out, drainage, screed, membrane and the tiles that cover them. How the published per-bathroom prices show it, and what moving the WC adds.
The answer
The most expensive part of a bathroom renovation sits under the tiles
The most expensive part of a bathroom renovation is the part that ends up hidden. Once the tiles go down, nobody sees the drain runs, the screed or the waterproofing membrane again, yet together with the strip-out and the tiling they make up most of the gap between a bathroom that is refreshed and one that is rebuilt. Every price below is per bathroom, the way UAE companies publish them.
What is the most expensive part of a bathroom renovation?
The work under the tiles: strip-out, drainage, screed, membrane and tiling. Three UAE companies publish both a refresh and a full renovation, and each starts the full job at two to four times the refresh, per bathroom: Revive Hub Renovations at AED 12,000 against AED 3,000, MBC Renovation Services at AED 15,000 against AED 5,000, and Vision Three at AED 35,000 for a full strip-out against about AED 15,000 for a cosmetic update. Sanitaryware and the vanity sit inside those bands. Moving the WC adds a drain run and, often, an approval on top. Our bathroom budgets page turns the bands into a total.
From refresh to rebuild, publisher by publisher
| Published by | Refresh: tiles and pipes stay | Full renovation | Rebuild against refresh, at the start |
|---|---|---|---|
| Revive Hub Renovations | AED 3,000 to 9,000 | AED 12,000 to 28,000, standard | Four times |
| MBC Renovation Services | From AED 5,000 | AED 15,000 to 20,000, modern | Three times |
| Vision Three | From about AED 15,000, cosmetic update | AED 35,000 to 60,000, full strip-out | About two and a third times |
The fittings do not explain that gap. A refresh swaps what can be unscrewed: taps, accessories, sealant, perhaps the vanity. The rebuild adds the demolition, new drainage, a screed laid to falls, the membrane and its flood test, and the tiling that covers all of it. ASM Interiors names most of them inside its band of AED 8,000 to 40,000 per bathroom, from the demolition and the waterproofing to the tiling, the plumbing and the ceiling.
Ask for the hidden work as its own line
Why does the hidden layer cost more than the fittings?
Because it is labour in sequence, and each stage waits for the last. The old tiles and screed come out by hand. The drains are set to their falls, the new screed must harden before the membrane is applied, each coat of membrane cures before the next, and the flood test holds water long enough to prove the result. A plumber, a waterproofing applicator and a tiler each take their turn in a room where only one trade fits at a time.
It is also the part that costs most to put right. The first sign of a failed membrane is usually water in the ceiling below, and reaching it means lifting the tiles above. Our guide to how waterproofing works sets out the layers and the test.
Does moving the toilet make a bathroom renovation cost more?
Yes, and it is the one change that adds a trade and paperwork at once. A WC drains by gravity to the soil stack; put it somewhere new and the floor has to be opened for a fresh run at the right slope, with the approvals following the drain.
- Emaar apartments: the Home Modifications factsheet does not permit MEP services to be relocated, so the WC stays where it is.
- Town Square townhouses: lifting wet-area floor tiles, which a new drain run needs, is a major alteration at AED 2,000 plus an AED 5,000 deposit. In its apartments the floor tiles may not be lifted at all.
- Dubai Municipality land: moving the WC is not on the no-permit maintenance list, and where the drawings change the job needs service 4127 through a registered consultant.
Our permit guide names the body that has to agree to each move.
What do sanitaryware and the vanity add?
No UAE company in these tables prices sanitaryware or a vanity on its own, so their cost sits inside the per-bathroom bands, which is why ASM Interiors can list both in a band that starts at AED 8,000. The spread comes from the model and from what has to be built in. A wall-hung WC needs a concealed frame fixed before the wall is tiled, and a concealed shower mixer is set into the wall at the same stage, so both are chosen before the rebuild rather than after it.
A like-for-like swap of fittings on the existing pipes is the refresh route, from AED 3,000 per bathroom, and the budget bathroom page shows how far it goes.
Which choices move a bathroom into the luxury band?
Size, stone and glass. The published luxury tiers start at AED 50,000 per bathroom on MBC Renovation Services' list and run to AED 150,000 and more on Bayut's, while Design Divine prices a spa-grade master bathroom at AED 60,000 to 200,000 and more. Between those tiers and the standard band the room grows and the materials change: natural stone where porcelain would do, glass to the ceiling, a bath and a shower side by side. Our ensuite page covers the master bathroom tier.
Why every price here is per bathroom
Because the fixed parts of the job repeat in every room: a drain connection, a membrane, a set of fittings, a tiler's visit. A villa with three bathrooms at the standard band of AED 15,000 to 45,000 each carries AED 45,000 to 135,000 in bathrooms alone, and one figure for all three cannot be checked against any published band. Ask for each room as its own line and read our bathroom prices row by row. The renovation hub weighs bathrooms against the kitchen in its whole-home answer, and our bathroom service prices each room from one brief.

Bathroom cost questions
- Is tiling or waterproofing the bigger cost?
- The published bands do not split them. Ask each quote to show the waterproofing product and the area it covers, and the tile allowance per square metre, as separate lines; then the two can be compared between contractors.
- Can I keep the tiles and still renovate?
- Yes, as a refresh, which the published bands start at AED 3,000 per bathroom. It cannot reach what is under the tiles, so a leak or a failed membrane needs the rebuild.
- Is a walk-in shower more expensive than a bath?
- The conversion is, since both the floor and the drain change: Town Square lists removing a bathtub for a flat shower as a major alteration at AED 2,000 plus an AED 5,000 deposit, for townhouses only. The walk-in shower page covers the build.
- Does a small bathroom cost less per square metre?
- Not per square metre: the drain, the membrane, the fittings and the trades are needed whatever the size, so a small room carries the same fixed costs over less floor. The published floor for a small room stripped and rebuilt at basic finishes is about AED 8,000.
- Does Corvana price the bathroom?
- No, the contractors you choose do. We ask each one to show the strip-out, drainage, waterproofing, tiling and fittings as separate lines, per bathroom, and we set the totals against the published bands. There is no charge to you.
