What We Fix

Common bathroom plumbing problems we fix

Leaking or running toilet — A constantly running cistern wastes hundreds of litres daily and adds up on your water bill. We replace inlet valves, floats, flush seals and cistern buttons same-day.
Shower mixer faults — Dripping shower heads, seized mixers and temperature control failures are all fixable without replacing the whole shower. We carry common cartridge replacements on the van.
Blocked basin or vanity drain — Hair, soap and product buildup slow bathroom basins quickly. We clear the trap and drain line and check the P-trap for damage while we're there.
Tap drips and worn washers — Bathroom basin taps and bath spout taps develop leaks as washers and cartridges wear. We repair or replace on the spot.
Cistern faults — Phantom flushing, slow fill, overflow or no flush at all usually come down to internal cistern components. We carry standard Caroma and Geberit parts.
Waterproofing-related leaks — Wet area leaks through grout, around the shower base or behind wall tiles often have a plumbing cause. We identify and fix the source before it causes structural damage.
Vanity and basin installations — Replacing an old vanity or upgrading a basin? We handle disconnection, new installation, waste connection and supply line hook-up.
Bathroom renovation rough-in — New bathroom build or full reno? We handle all the plumbing rough-in — waste positions, supply lines, wall penetrations — ready for tiling.

How It Works

Our process

Same-day arrival

We aim to attend within 2–4 hours across Southwest Sydney. Bathroom leaks that are causing water damage are treated as emergencies and prioritised.

Inspect and quote

We diagnose the issue, explain what's needed, and give you a fixed upfront price. No work starts until you approve the quote.

Complete the repair or install

We carry common parts for toilets, mixers, taps and basins. Most repairs are done in a single visit. Larger renovation scope is quoted and scheduled to suit you.

Test, clean up, sign off

We test all connections under pressure, clean up the work area, and walk you through what was done. You get a licensed plumber's invoice with licence number — and a Certificate of Compliance for notifiable work as required by NSW Fair Trading.

FAQs

Common questions

How much does bathroom plumbing cost in Sydney?

It depends on the job. Toilet repairs from $250, tap replacements from $180, full toilet replacement from $450, vanity installs from $400. We give an upfront fixed quote every time.

Can you fix a running toilet same-day?

Yes. A constantly running toilet is almost always a cistern valve, float or flush seal issue. We carry standard parts and fix most running toilets in a single visit.

Do you do full bathroom renovations?

We handle the complete plumbing component of bathroom renovations — rough-in, fixture installation, waste connections and final sign-off. We work alongside your tiler and builder.

My shower is leaking through the wall. What should I do?

Turn off the shower and call us. Wall leaks from showers can cause serious structural damage if left. We find the source — often a failed mixer seal or shower waste — and fix it properly.

Can you install a new toilet the same day?

In most cases yes. We carry standard toilet suites and can do same-day toilet replacements across Southwest Sydney.

Do I need a licensed plumber for bathroom work in NSW?

Yes. DIY plumbing work in NSW must be done by a licensed plumber — unlicensed work is illegal under the Plumbing and Drainage Act 2011 and can void home insurance claims.

Are you available on weekends for bathroom emergencies?

Yes, 24/7 including weekends and public holidays. For urgent bathroom leaks call us or see our emergency plumber page. After-hours rates apply.
