What makes an ensuite different
An ensuite is the private bathroom attached to the master bedroom. It is smaller than the main family bathroom — typically 3 to 5 square metres — and is used by one or two people rather than the whole household.
Because it is private, the design can be more personal. Bold tiles, premium fixtures and a spa-like feel work well in an ensuite because they suit the couple who uses it, not the needs of children, guests and daily household traffic.
Layout options for a small ensuite
The three fixtures in most ensuites are a shower, a vanity and a toilet. In a small room, the layout sequence matters. The most common and space-efficient layout puts the vanity nearest the door, the toilet beside or opposite it, and the shower at the far end.
A long, narrow ensuite suits a linear layout — all three fixtures along one wall. A wider room allows an L-shaped layout with the shower tucked into a corner. Our layout changes guide covers the cost and process of moving fixtures.
In some master bedrooms, the ensuite has no external wall and therefore no window. In that case, a quality exhaust fan and good lighting are essential — see ventilation below.
Design priorities
In a small ensuite, the shower does the most work. A frameless shower screen opens the room visually and lets light flow through. A walk-in (curbless) shower removes the step and makes the room feel larger. Our shower screen guide compares frameless, semi-frameless and framed options.
The vanity should include as much drawer storage as the width allows — an ensuite has less wall space for hooks and shelves. A mirror cabinet doubles as both mirror and storage. Our vanity comparison guide helps decide between a single and double vanity.
Ventilation and moisture
An ensuite attached to the bedroom needs excellent ventilation to prevent moisture migrating into the bedroom, the wardrobe and the carpet. A ducted exhaust fan rated for the room volume is essential — not optional.
The exhaust fan should run during and for 15 to 20 minutes after every shower. A humidity-sensing fan turns on and off automatically. Our ventilation guide covers fan sizing, ducting and building code requirements.
Lighting in a windowless ensuite
Many ensuites have no external window or only a small one. Layered lighting compensates: a ceiling downlight for general brightness, a backlit mirror or LED strip for task lighting at the vanity, and an accent light (niche LED, under-vanity strip) for atmosphere.
A skylight or sun tunnel is an option if the ensuite is on the top floor. Natural light transforms a small, internal room. Our lighting guide covers the principles of bathroom lighting design.
Storage in a tight space
An ensuite serves one or two people, so the storage needs are smaller than a family bathroom. A vanity with drawers, one or two shower niches and a mirror cabinet usually cover everything. A recessed toilet roll holder saves space on a narrow wall.
Our storage planning guide walks through how to list what needs a home and assign each item to the right storage type.

Frequently asked questions
How small can an ensuite be?
A functional ensuite with a shower, vanity and toilet can fit in as little as 2.5 square metres. Below that, the room becomes too tight to use comfortably. Most ensuites are 3 to 5 square metres.
Does an ensuite renovation add value to a home?
Yes. A modern ensuite is one of the top features buyers look for in a master bedroom. The return on a well-done ensuite renovation is typically 60 to 80 per cent of the cost.
Should I include a bath in the ensuite?
Only if the room is large enough (at least 6 square metres) and you genuinely use a bath. In a small ensuite, a spacious shower is a better use of space. Keep the bath in the family bathroom if the home has one.
How much does an ensuite renovation cost?
A like-for-like ensuite renovation starts from about $18,000 with ETR, depending on the size and finishes. Premium finishes, layout changes or a freestanding bath push the price higher. A free on-site measure gives you a fixed-scope quote.
Can I add an ensuite where there was not one before?
Yes, if the plumbing can be connected to the existing waste and supply lines. Adding an ensuite typically costs $25,000 to $50,000 depending on whether walls need building, plumbing needs extending and the level of finish.
