How Long Does a Renovation Take? Realistic 2026 Timelines
Realistic 2026 timelines for a Northern Beaches renovation — how long design, approvals, material lead times and the on-site build actually take, and what causes delays.
A bathroom renovation on Sydney's Northern Beaches usually takes 2 to 3 weeks on site and a kitchen 3 to 4 weeks, while a full-home renovation runs 8 to 16 weeks. Start to finish — including design, finish selection and material lead times — a bathroom is realistically 6 to 10 weeks and a full home 4 to 8 months. The build itself is only part of the story.
Renovation timelines at a glance
Here's how long each type of project typically takes for local homes. The first column is the hands-on-tools build; the second is the honest end-to-end timeline once design, approvals and lead times are counted.
| Project type | On-site build | Total start to finish |
|---|---|---|
| Bathroom | 2 – 3 weeks | 6 – 10 weeks including design, finishes and lead times |
| Kitchen | 3 – 4 weeks | 8 – 12 weeks including custom joinery and stone lead times |
| Full-home renovation | 8 – 16 weeks | 4 – 8 months including design, approvals and lead times |
| Unit / apartment | 3 – 6 weeks | 8 – 14 weeks including strata approval and lead times |
Every home is different — an older federation cottage or a strata block will run differently to a 1990s brick home. The only way to get a firm date is a fixed-price quote with a signed completion day.
The four stages that make up your timeline
1. Design and selections
Every renovation starts here, and it's where most of the calendar quietly disappears. Settling on a layout, then choosing tiles, tapware, cabinetry finishes, stone and appliances usually takes two to four weeks. The faster you make decisions, the sooner everything else can begin — indecision at this stage is the number-one reason a project drifts.
2. Approvals
A like-for-like kitchen or bathroom that doesn't move external walls or drainage generally needs no council approval, so there's nothing to wait on. If you're removing a wall, changing the footprint or relocating services you may need a Complying Development Certificate — allow two to six weeks. In a unit or apartment you'll also need strata sign-off, which we help you prepare early so it doesn't hold up the build.
3. Material lead times
This is the stage people forget. Custom cabinetry is made to measure and typically takes four to six weeks; stone benchtops are templated only after the cabinets are in, then fabricated and installed. Special-order tiles, tapware and appliances can each carry their own wait. Ordering everything early — before a single tool is picked up — is what keeps the on-site phase short and continuous.
4. The on-site build
This is the part most people picture when they think renovation, and it's the fastest-moving stage when it's run properly. A bathroom is 2 to 3 weeks, a kitchen 3 to 4, because trades follow one another in a tight, pre-planned sequence rather than waiting on each other.

Why our on-site build runs to 21 days
The on-site phase is fast for one reason: sequencing. Because our 18 trade teams are all in-house — plumbers, electricians, waterproofers, tilers, cabinet makers, stonemasons and painters — one foreman lines them up back to back with no gaps waiting on an outside subbie to turn up. Waterproofing cures overnight, tiling follows, then fit-off, then finishing. That controlled rhythm is what lets us commit to a signed date under our 21-day guarantee for standard kitchens and bathrooms — miss day 21 and the overrun is on us.
What actually causes delays
- Late finish selections. A tile or tapware choice made mid-build stops the tiler and pushes everything behind it.
- Material lead times ignored up front. Ordering stone or cabinetry after the strip-out guarantees a gap on site.
- Variations mid-project. Changing the layout once services are roughed in means re-doing work already done.
- Hidden issues. Old plumbing, rot or non-compliant wiring found when walls open up — more common in older federation and character homes.
- Juggling your own trades. When subbies aren't coordinated by one team, every handover becomes a waiting game.

Frequently asked questions
Most standard bathrooms take two to three weeks on site once materials are in. Allow six to ten weeks in total once you factor in design, finish selection and waterproofing cure times. At Reno Build the on-site build runs to a signed date under our 21-day guarantee.
A kitchen is usually three to four weeks on site, but custom cabinetry and stone benchtops carry a four-to-six-week lead time before installation. That's why the full journey is closer to eight to twelve weeks.
The biggest causes are late finish selections, custom material lead times, variations mid-build, and hidden issues found once walls open up. Locking in every choice before we start is the single best way to stay on schedule.
The 21-day guarantee covers the on-site build for our standard fixed-price kitchen and bathroom jobs, not the design and material lead times that come first. We give you a signed completion date up front so you always know where day 21 lands.
A like-for-like renovation often needs no approval, so there's no wait. If a CDC or strata sign-off is required, allow two to six weeks — we start the paperwork early so it runs alongside design rather than holding up the build.
