Fixtures are where a granny flat bathroom either looks finished or looks cheap. The tiles and layout do the structural work — but the tapware is what people actually touch and look at every day. In a rental granny flat, fixtures also have to survive years of tenant use without failing. The good news is that getting fixtures right does not require a big budget. A few clear decisions — finish, style, water efficiency rating — cover most of what matters. Below is a breakdown of the four fixture categories, what to look for in each, and what they cost in Australia.

WELS Ratings — What You Need to Know
The Water Efficiency Labelling and Standards (WELS) scheme is mandatory in Australia — all tapware, showers and toilets sold must carry a WELS rating. The rating runs from 1 to 6 stars, with more stars meaning less water used.
For a granny flat, aim for WELS 4-star minimum on taps and showers, and 4-star dual flush on toilets. Higher-rated fixtures reduce water bills for the tenant and demonstrate compliance if council asks for evidence of water efficiency in a new build.
You can check any product’s WELS rating at the official register before purchasing — it is listed on the product’s packaging and often on the retailer’s website.
Will Council Care About My Fixtures?
In most cases, no — fixture selection is an interior decision that does not require council approval. What council and the plumbing code do require is that all plumbing work is carried out by a licensed plumber and that fixtures meet WELS minimum standards.
If you are moving plumbing points (relocating the basin, shower or toilet) as part of a renovation, this may require a plumbing permit depending on your state — check with your local council or a licensed plumber before starting.
