Ensuite renovation cost in Sydney

Quick answer: ensuite renovation cost in Sydney

Renovating an existing ensuite in Sydney costs $13,000 to $24,000 in 2026, with most jobs around $18,000. A cosmetic refresh that keeps the layout can start from $8,000 to $12,000, while a premium ensuite with stone, a frameless screen and a freestanding tub or double vanity can push past $25,000.

Adding a new ensuite to an existing bedroom is a separate job - typically $25,000 to $35,000+ - because you are building a wet area where there wasn't one. The rest of this guide covers both, what moves the number, whether an ensuite adds value, and how to keep the cost down in Sydney.

Renovating an ensuite vs adding a new one

The single biggest factor in ensuite cost is whether the room already exists:

• Renovating an existing ensuite ($13,000-$24,000): you are replacing fittings, tiling and waterproofing in a room already plumbed and framed. Same trades as a main bathroom, smaller footprint.
• Adding a new ensuite ($25,000-$35,000+): you are building stud walls, a door, new plumbing runs to the room, electrical, ventilation and a full fit-out. In a Sydney home this often means cutting into an existing bedroom or robe and running pipes back to the nearest stack.

If you are pricing a small main bathroom rather than an ensuite, see our small bathroom renovation cost guide - the two overlap in size but differ in fit-out.

Why an ensuite costs more per square metre than the main bathroom

An ensuite is usually the smallest wet room in the house, yet it carries one of the highest per-square-metre rates - often $4,000 to $5,500 per m2. The reasons mirror small bathrooms, only more so:

• Fittings are dense. A shower, toilet, vanity and sometimes a bath are packed into 4-6 m2, so you buy almost a full bathroom's worth of product for a fraction of the floor.
• Fixed costs don't shrink. Waterproofing, the plumber's and tiler's minimum attendance, and electrical are priced per job, not per tile.
• Specifications are higher. Ensuites attached to a main bedroom are often finished to a higher standard than a second bathroom - stone tops, niches, heated floors - which lifts the rate.

Cost to add a new ensuite to a bedroom in Sydney

Adding an ensuite where none exists carries extra line items on top of a normal fit-out:

That's why a new ensuite lands at $25,000-$35,000+ rather than the $13,000-$24,000 of a like-for-like renovation. Distance to the nearest soil stack is the wildcard - the further the pipes have to run, the higher the plumbing bill.

Where the money goes in a Sydney ensuite

A typical $18,000 ensuite renovation in Sydney breaks down roughly like this:

Itemised example: Mosman ensuite, 5 m2

A 2026 renovation of a 5 m2 ensuite in a Mosman home - full strip-out, same layout, stone-top vanity, frameless screen, porcelain tiles, heated floor:

• Strip-out and disposal: $1,200
• Plumbing: $3,200
• Waterproofing: $900
• Tiling (supply + lay): $4,800
• Electrical (incl. heated floor): $1,600
• Stone-top vanity, toilet, tapware, screen: $4,800
• Labour and management (balance): $1,500

Total: ~$18,000. The higher tiling and fitting spend reflects the premium finish typical of North Shore ensuites.

Does an ensuite add value in Sydney?

In the Sydney market, a well-finished ensuite is one of the more reliable renovation spends for resale - a main bedroom with its own ensuite is a strong selling point, especially in family homes and apartments. Adding a second bathroom to a one-bathroom home also lifts how the property is listed and appraised. As with any renovation, the value comes from a clean, neutral, well-built finish rather than the most expensive fittings.

How to keep an ensuite renovation affordable

• Keep the layout. Leaving the toilet, shower and vanity where they are avoids new plumbing and re-waterproofing - the biggest avoidable cost.
• Refresh if the waterproofing is sound. No leaks and an intact membrane? A cosmetic refresh can save you thousands.
• Skip the bath. A shower-only ensuite saves space and cost; most buyers expect the bath in the main bathroom anyway.
• Choose local tiles and a standard-size vanity to avoid custom joinery premiums.
• Get three quotes. Ensuite pricing varies widely between Sydney trades - comparing three keeps it honest.

How much does it cost to add a new ensuite?

Adding a new ensuite to an existing bedroom in Sydney typically costs $25,000 to $35,000 or more, because you are building stud walls, running new plumbing and electrical, and fitting out a wet area from scratch. The distance to the nearest soil stack is the biggest variable.

Why does an ensuite cost more per square metre than a main bathroom?

An ensuite packs a shower, toilet and vanity into 4-6 m2, so you buy nearly a full bathroom of fittings for a fraction of the floor area. Waterproofing, plumbing and tiling minimums are priced per job, not per tile, and ensuites are often finished to a higher standard - all of which lift the per-m2 rate.

What is the difference in cost between renovating and adding an ensuite?

Renovating an existing ensuite is $13,000-$24,000 because the room is already framed and plumbed. Adding a new ensuite is $25,000-$35,000+ because it includes stud walls, a door, new plumbing and electrical runs, ventilation and making good - roughly $9,000-$15,000 of extra work on top of a normal fit-out.

Does adding an ensuite add value to a Sydney home?

Generally yes. A main bedroom with its own ensuite is a strong selling point in the Sydney market, and adding a second bathroom to a one-bathroom home improves how it is listed and appraised. The value comes from a clean, neutral, well-built finish rather than the most expensive fittings.

How long does an ensuite renovation take in Sydney?

A standard ensuite renovation takes about 2 to 3 weeks once on site, allowing drying time for waterproofing. Adding a new ensuite takes longer - typically 3 to 5 weeks - because of the extra building, plumbing and electrical work.

Can you put an ensuite in any bedroom?

Usually, but cost depends on how far the new plumbing has to run to reach the nearest soil and water lines. Bedrooms backing onto an existing bathroom or wet wall are cheapest to convert; rooms far from existing plumbing cost more. In a strata building you will also need owners corporation approval.

Do I need approval for an ensuite renovation in Sydney?

A like-for-like ensuite renovation rarely needs council approval. Adding a new ensuite may, depending on structural and plumbing work. In a strata building, both usually require owners corporation approval and a waterproofing certificate, since the works affect common-property waterproofing - check your by-laws first.
