Most Northern Beaches bathrooms were built for a different era, and trying to get ready in a cramped, poorly planned space is a total nightmare! At GRH Plumbing, we don't just swap out tiles; we reconfigure the layout so your bathroom finally works for your lifestyle instead of against it.
We handle the heavy lifting that makes a full bathroom renovation actually last, starting with the behind-the-wall pipework and moving drains so your new shower and toilet end up exactly where they make the most sense.
From installing custom walk-in showers to modern wall hung vanities, we make sure the plumbing is bulletproof so that once those new tiles go down, you never have to think about what’s underneath them again.

We’ve plumbed bathrooms of every layout and size you can imagine, including:
If you’re changing your bathroom layout, you aren't just moving a toilet or a vanity, you’re moving the plumbing that feeds them. This is the "rough in" stage, where we get into the walls and under the floor to relocate your water pointsand waste stacks.
On the Northern Beaches, we often deal with older plumbing that wasn't designed for modern, high pressure fixtures. We don’t just "make it fit"; we make sure your new pipes are sized correctly and positioned perfectly.
By getting the behind the wall pipework right now, we make sure you don't have to deal with slow drains or rattling pipes once your beautiful new tiles are installed.
The shower and bath are the centrepieces of your renovation, but they’re also the biggest leak risks if the plumbing is rushed. Whether it’s a freestanding bath or a walk-in shower, we focus on more than just the look.
We make sure your shower base has the right slope so water actually heads for the drain, and we secure every connection to handle high pressure rainfall heads without a rattle. It’s about getting the fit off perfect so your new bathroom feels like a luxury retreat, not a patch up job that’s going to leak into the floorboards in six months.
This is the finishing stage where your renovation finally comes together. On the Northern Beaches, wall hung vanities are the gold standard for making smaller bathrooms feel open, but they leave no room for error. The plumbing has to be millimetre-perfect behind the wall, or you’ll end up with messy, exposed pipes that ruin the floating look.
We don’t just hook up your taps and walk away. We specialise in installing everything from concealed cistern toilets to designer mixers and double basins.
We make sure your tapware is secured tightly, the drainage is whisper-quiet, and every fixture is aligned perfectly.
A toilet is a major part of your bathroom's footprint, and on the Northern Beaches, the shift is toward back-to-wall or concealed cistern models. These look sleek and save space, but they require the in-wall plumbing and waste positioning to be spot on before the tiles go down.
We handle the tricky stuff, like relocating waste pipes through concrete or retrofitting rimless toilets into older systems. We make sure the flush is powerful, the cistern is quiet, and the seal is watertight. It’s about ensuring your most used fixture is reliable and fits the modern look of your new space.
There’s nothing worse than finishing a high end reno only to find your new rainfall shower has the pressure of a garden hose. Many older Northern Beaches homes struggle with outdated gravity-fed systems or undersized lines that just can’t keep up with modern fixtures.
We make sure your hot water system and pipe sizing are up to the task before the walls go back on. Whether it’s upgrading to a continuous flow system or boosting your mains pressure, we ensure you get that luxury hotel shower feel every single morning, without the temperature dropping the second someone else turns on a kitchen tap!
If your current bathroom layout feels awkward, it’s usually because the original plumber took the easy route 🙄. We don't just work around where the pipes already are; we move them to where they make sense.
Whether that’s shifting a toilet waste through a concrete slab or relocating taps for a double vanity, we handle the heavy lifting. This can often mean updating old, rigid pipework so it actually lines up with your new floor plan.
We make sure every drain and water point is spot on and rock solid before the floor goes down, so your new layout works perfectly from day one.
