Independent guide — not a contractor. Planning information only. Confirm licences, waterproofing, and quotes with qualified trades and the relevant state authority.
| Measure | Usual role | Limit |
|---|---|---|
| Ducted exhaust | Clear steam before it hits a robe or a ceiling | A fan that dumps into the roof void is not a strategy |
| Heat lamp / 3-in-1 | Short warm-up on a winter morning | Not a substitute for extraction |
| Under-tile heat | Comfort if the floor is already open | A luxury line in the bathroom cost band |
| Hydronic | Makes sense if the house already has it | Do not invent a boiler for one ensuite |
Extraction is the first comfort product. Heating is second. Confirm electrical and any wet-area rules with licensed trades.
