The plumbing that makes a reno work

A great bathroom starts behind the walls. We set the plumbing up right at rough-in and finish it off cleanly at fit-off, so your new bathroom looks the part and works for years.

Full bathroom renovations

All the plumbing for your bathroom reno, coordinated with the other trades.

Rough-in plumbing

Water, waste and drainage set out for every fixture before tiling.

Fit-off & fixtures

Tapware, toilets, basins, baths and showers installed and tested.

Waterproofing coordination

We work in with your waterproofer so penetrations are done right.

New builds & extensions

Plumbing for new homes and additions, rough-in through to handover.

Laundry & kitchen plumbing

Renovating more than the bathroom? We plumb laundries and kitchens too.

How it works

In step with your renovation

Plan

We look at the layout and fixtures and set out the plumbing with you.

Rough-in

Water, waste and drainage installed behind the walls before tiling.

Work in with trades

We time our stages around the tiler, waterproofer and other trades.

Fit-off & test

Fixtures installed once tiling's done, then everything tested and checked.

Before rough-in

Six decisions worth making early

Once the pipework is in the wall and the waterproofing is on, changing your mind gets expensive quickly. These are the ones that catch people out, and all of them are cheap to decide and dear to revisit.

Where the toilet goes

The single most expensive decision in the room. Moving a toilet means moving the soil pipe, and on a slab that means cutting concrete. Leaving it where it is, even by half a metre, can be the difference between a straightforward reno and a structural one.

Wall-hung or floor-mounted vanity

Wall hung looks lighter and makes the floor easier to clean, but the waste and the taps have to come through the wall, which means the plumbing goes in before the wall is sheeted. Decide this before rough-in, not when the vanity arrives.

Wall mixers or deck mixers

Wall mixers mean the valve sits inside the wall cavity. It is a better look and it is harder to change later, so it needs to be settled at rough-in with the exact tapware on hand, because every brand sits at a different depth.

Floor waste position and fall

The floor has to fall to the waste, and the waterproofer and tiler both work to that. Get it wrong and water sits in a corner of the shower forever. This is a millimetres job, not a near enough job.

Niche or no niche

A shower niche has to miss the studs and anything running through the wall. It is easy at frame stage and close to impossible afterwards.

Heated towel rail and underfloor heating

Both are electrical rather than plumbing, but both have to be coordinated before the walls close and before the screed goes down. Worth raising early so nobody is chasing an electrician at tiling stage.

How it runs

The order a bathroom actually goes in

Plumbing happens twice in a bathroom, at rough-in and again at fit-off, with weeks of other trades in between. Knowing that makes the whole thing easier to plan.

Strip out

Everything out, back to frame and slab. This is when anything hidden shows up, which is usually old galvanised pipework, a waste that was never done properly, or a leak nobody knew about.

Rough-in

All the pipework goes in while the walls are open. Water, waste, vents. Nothing looks finished at the end of this and it is the stage that decides whether everything after it goes smoothly.

Waterproofing and screed

Not our trade, but it has to happen against our falls and our penetrations. We coordinate with whoever is doing it rather than leaving the two to meet by accident.

Tiling

Also not ours. The point is that once it starts, our rough-in is locked in behind it.

Fit-off

Tapware, toilet, vanity, shower, everything connected and tested. This is the week it starts looking like a bathroom.

Test and hand over

Everything run, every connection checked, and a look at the things that cause callbacks later rather than the things that look good today.

Bathroom renovation questions

Do you do the whole bathroom or just the plumbing?

We handle the plumbing side of the renovation, from rough-in through to fit-off, and work alongside your tiler, waterproofer and other trades. If you need a hand lining up the rest, just ask.

What's involved in rough-in and fit-off?

Rough-in is the pipework behind the walls and floor before tiling, setting up water, waste and drainage for every fixture. Fit-off is installing the tapware, toilet, basin, bath and shower once the tiling's done, then testing it all.

How long does the plumbing on a bathroom reno take?

The plumbing happens in stages around the other trades. Rough-in is usually a day or two, then fit-off later once tiling and waterproofing are done. We work to the project's program so we're not holding up the job.

Can you install my chosen tapware and fixtures?

Yes. Bring your own tapware, toilet, basin and shower fittings and we'll install them properly, or we can advise on what works well if you're still choosing.

What usually turns up once the old bathroom comes out?

Old galvanised pipework is the common one in homes of a certain age, and it is worth replacing while the wall is open rather than after the tiling. Waste pipes with poor fall, and shower wastes that were never connected properly, also turn up regularly. We price anything extra before doing it rather than presenting it afterwards.

Do I need to move the toilet?

Usually not, and it is worth resisting if you can. Moving a toilet means relocating the soil pipe, and on a concrete slab that means cutting it. If the layout really does need it we will tell you what is involved before you commit to the design rather than after.

Can you work with my builder or tiler?

Yes, and that is how most of these run. Rough-in has to be finished and checked before the waterproofer starts, and fit-off happens after tiling. We work to whoever is running the job, or coordinate it ourselves if nobody is.

How long is the bathroom out of action?

It depends on the scope and on how tightly the other trades are booked, and the plumbing is rarely the long pole. The two stages that matter to us are a few days each. What stretches a bathroom reno is usually waiting on waterproofing cure times, tiling and whether everything was ordered in time.

What if a drain is blocked or slow before we start?

Worth sorting before the reno rather than during it, because a blockage behind a brand new wall is a bad place to find a problem. Our blocked drains page covers how we diagnose it.

What happens if you find a problem behind the wall?

Old pipework and drainage faults turn up regularly once a bathroom is stripped, and it is better found then than after the tiling. We price any extra work before doing it. If the drainage is the issue, our blocked drains page covers how we diagnose it.

Which areas do you cover?

The whole Northern Beaches, including Frenchs Forest, Allambie Heights, Forestville, Killarney Heights, Belrose, Davidson, Beacon Hill, Cromer, Narraweena, Wheeler Heights, Brookvale, North Manly, Manly Vale, Dee Why, Balgowlah, Seaforth, Manly, Freshwater, Collaroy, Narrabeen, Elanora Heights, Mona Vale and Bilgola. Based in Frenchs Forest, so most of the area is a short run.
