Timing
The approval depends on what moves, the build on the drain and the membrane, and both on the hours your community lets a contractor work. Only the approval side is published anywhere.
The timeline
The time a bathroom renovation takes splits into three parts, and only one of them is published. The approval, where one is needed, has a stated turnaround. The build depends on the contractor, the drain and the waterproofing. The third part is the calendar: the hours and days your community allows noisy work, which decide how much of each week the job can use.
How long does a bathroom renovation take?
Plan for the build plus up to five working days of approval, and get the build in writing. Replacing fittings like for like needs no permit in Dubai Holding communities, and Emaar exempts regular maintenance from its NOC. Emaar processes a minor or major works NOC in 3 business days from a complete file, and Town Square decides minor alterations in 2 working days and major ones in 5. No UAE company publishes a build time for a bathroom, so we ask every contractor to state the programme in working days, with the membrane's cure and the water test shown as steps of their own.
| Kind of job | Approval it needs | Published wait |
|---|---|---|
| Fittings replaced like for like | None in Dubai Holding communities; Emaar exempts regular maintenance | None, though the contractor still needs an entry permit |
| Any job in a Dubai Holding community | A request on the community app | At least 24 hours ahead, or 72 by email |
| Any alteration in an Emaar community | Home Modifications NOC | 3 business days from a complete file |
| New tiles over the old, Town Square | Minor alteration | 2 working days |
| Bath replaced by a walk-in shower, Town Square | Major alteration, townhouses only | 5 working days, with an AED 5,000 deposit |
| Walls moved on Dubai Municipality land | Community approval plus service 4127 | 3 working days for the Municipality permit |
| Maintenance permit, Abu Dhabi | Filed by the contractor | 7 working days; 5 in Al Ain and Al Dhafra |
| Maintenance permit, Ajman | Open to owners and contractors | 2 days, at AED 1,000 |
Sharjah publishes the steps for its residential maintenance permit but no turnaround, so there the contractor writes the expected days into the quote, as our Sharjah page explains. Everywhere else, the wait only starts once the file is complete: Emaar's 3 days count from complete and correct documents.
Four things, in the order the job meets them. The strip-out comes first, and it disappears from the floor where the building keeps the old tiles, as Emaar and Town Square do in apartments. The drain is next: reused where it is, it takes little time; moved, it means opening the floor to the soil stack. Then the waterproofing, which cannot be hurried. Last come the tiles, the fittings and the glass, and the glass can only be measured once the tiles are on. The full sequence, with what each stage waits for, is on our order of works page.
A refresh, which keeps the tiles and the pipes, skips most of that list, which is part of why its published band starts at AED 3,000 against AED 8,000 for a full renovation. Both figures are per bathroom and sit with their sources on our price page.

Our guide to how waterproofing works explains why the membrane steps take the time they do. A programme with no time shown for them is a programme that skips one.
Breaking out tiles and cutting new ones is noisy work, and noisy work has its own windows. In Dubai Holding communities it runs from 9am to 1pm and 3pm to 5pm, inside a minor-works day of 8am to 6pm, Monday to Saturday, with nothing on Sundays or public holidays. Emaar's 2026 villa rules allow noisy work from 10am to 1pm and 3pm to 5pm, and its apartment rules start an hour earlier. Town Square works from 9am to 5pm on business days, and no worker may stay overnight. The apartment site keeps the full working hours table for every developer.
Not the one being rebuilt, from the day the WC comes out to the day it goes back in. In a villa with several bathrooms that is a matter of sequence: renovate one at a time and keep another in use. In a flat with a single bathroom, plan for the days without it before the contractor starts, and ask for the WC to go back into service as early in the programme as the floor allows.
The crew needs facilities too. Dubai Holding's rulebook requires portable toilets inside the work site for major works, and no worker may stay in the unit beyond the permitted hours, so your remaining bathroom is not the site's. Water is the other thing to plan: the supply to the bathroom is isolated for part of the job, and the contractor should say for how long.
The site work can be simpler than in a villa, and the logistics around it slower. Where the building keeps the old floor, there is no floor strip-out, and where MEP may not move, there is no new drain run. The waiting sits in the building instead: service lifts booked by the slot, deliveries in fixed windows and the management's own notice periods. Aldar's Abu Dhabi community handbooks, for example, cap a lift booking at two hours and want 48 hours' notice for bulk deliveries. For Dubai towers, the apartment site's guide to moving materials goes building by building.
The paperwork closes the job. In Dubai Holding communities the owner notifies completion, the community inspects within about 21 days, and anything out of line has to be put right within 30. On Trakhees land the Modification Completion Certificate is targeted at 3 working days, and the premises may not be used until it is issued. Ajman's permit deposit has its own refund service, with a stated duration of 7 days once the approved conditions are met. Hold the final payment until the snag list is closed; the hub's payment schedule guide shows how to stage it, and our bathroom service asks every contractor for the programme and the completion steps in the same brief.
