Installing a shower filter is one of the easiest ways to get cleaner water and softer skin — but in Australia, the hardest part is finding one that actually fits.
Here’s everything you need to know: from thread sizes and pressure tips to how to install your shower filter in minutes (no plumber, no leaks).
1. Check this first: Australian showers use BSP threads
Almost every shower in Australia uses a ½-inch BSP (British Standard Pipe) thread.
That means any shower filter you buy must clearly state BSP-compatible.
If it doesn’t, it’s probably built for U.S. NPT threads, which don’t seal properly and can cause leaking or damage.
The Watego Shower Filter is built specifically for Australian BSP fittings, guaranteed to fit, leak-free, and keep your pressure strong.
2. What you need before installing
You’ll only need:
-
A shower filter (BSP-compatible)
-
A shower 😉
-
Plumber’s tape (only if your fittings are old or corrode).
-
Optional: pivot adapter for tight wall spaces
3. How to install a shower filter (DIY guide)
-
Remove your shower head. Unscrew it gently (clockwise facing wall).
-
Attach your shower filter. Screw it on by hand — no tools needed.
-
Reattach your shower head. Tighten by hand until snug.
-
Run hot water for 1–2 minutes to flush carbon dust.

4. Tight spacing? Here’s the fix
Some showers sit too close to the wall, leaving little room to attach a filter.
If your filter bumps into tiles or can’t sit straight, don’t force it — you just need a pivot adapter.
A pivot adapter extends the filter slightly away from the wall, giving you the clearance you need.
5. How often to change your shower filter cartridge
In Australia it's best to swap your cartridge every three months (10,000 - 15,000L) for best results (or when the chlorine smell or dryness returns).
Most modern filters twist open for quick refills.
6. Why Australian water needs a different filter
Australian tap water is treated with chlorine, which can be harsher than what filters overseas are tested on. Combine that with hotter showers and higher pressure, and generic filters often underperform here.
When comparing shower filters, look for:
-
BSP fittings for leak-free installation
-
Independent chlorine-reduction testing
-
Australian customer support and refill supply
7. Final thoughts
Installing a shower filter in Australia should be simple.
Pick a BSP-compatible filter, twist it on, and if your shower’s tight against the wall, add a pivot adapter so everything fits neatly.
Start with one made for Australian water, like Watego Shower Filter and enjoy softer, cleaner water every day.
