Bathroom Renovation in Dubai: Waterproofing First, Then Tile
If your Dubai villa bathroom is leaking into the salon, do not start with a tile catalogue. Waterproofing, falls, and plumbing sequence decide whether the renovation lasts.

Bathroom renovation Dubai searches spike when water stains the salon ceiling or grout turns black after one winter. That is commercial intent: you need a contractor who starts with plumbing and membranes, not a porcelain brochure.
Jamal Alfan does tile and bathroom work for villas and apartments in Dubai, Abu Dhabi, and Sharjah. Waterproofing is in the sequence, not an upgrade you have to remember to ask for.
Bathroom renovation cost in Dubai (indicative 2026)
Fixtures you supply vs we supply changes the lump — say which in the brief
| Scope | Typical range (AED) | Must include |
|---|---|---|
| Grout + silicone refresh | 800 – 2,500 | Mould treatment, not just colour |
| Re-tile on existing falls (risky) | 4,500 – 12,000 | Why membrane is being reused |
| Full wet room: membrane + tile + sanitary | 18,000 – 40,000+ | Falls, upstands, waste test |
| Layout change (move WC or shower) | survey | Plumbing chase, slab rules, downstairs finish |
The only sequence that belongs in a Dubai wet room
- Strip and inspect plumbing; pressure-test supplies and waste.
- Set falls to the drain — shower trays that pond are already failing.
- Apply membrane with upstands behind the future tile line; allow cure time.
- Tile, grout, silicone at movement joints; then a water test before the ceiling below is painted.
Villa vs apartment bathrooms
Jumeirah and Arabian Ranches villas often have a guest WC plus two family bathrooms — you can keep one live. Marina and Downtown apartments usually have one bathroom; the job needs a hotel night or a very tight shutdown plan. Building management rules on noisy hours are part of the programme, not a surprise.
What to send for a quote
- Photos of floor, walls, shower, and the ceiling in the room below if stained.
- Whether you keep the layout or move the WC / shower.
- Who supplies sanitary ware and stone.
- Community name — access and parking change the day count.

Questions this guide answers
How much does a bathroom renovation cost in Dubai?
Indicative 2026 ranges for a typical villa bathroom: AED 8,000–18,000 for a refresh with existing layout; AED 18,000–40,000+ when waterproofing, new falls, fixtures, and full tile are in. Guest WCs are less; marble wet rooms and layout moves are more. A leak into the room below is a bigger job than the bathroom you can see.
How long does a villa bathroom renovation take?
A single bathroom with waterproofing and tile is commonly 10–21 working days once fixtures are on site. Occupied villas need a usable alternative WC. Do not accept a five-day quote that skips membrane cure time.
Do you waterproof before tiling in Dubai villas?
Always. Wet rooms fail when tile is treated as waterproofing. We detail membranes, upstands, and falls, then tile. Grout is not a tanking system.
Can you renovate a bathroom in an occupied apartment in Marina?
Yes, with building access rules, protection of the corridor, and a sequenced shutdown of water. Photos of the bathroom and the ceiling below (if you have them) shorten the first visit.
