Bathroom renovation plumbing
We do the plumbing on bathroom renovations — working directly for homeowners, or alongside your general contractor or designer. That covers moving and rerouting supply and drain lines, the rough-in, fixture installation, and the permit.
If you're at the planning stage, the section below is the one worth reading. A few decisions made before the walls close are cheap now and very expensive later.
Decide these before the walls close
Where the toilet goes. Moving a toilet means moving the drain, and drains need fall. In a slab or a condo, that can range from difficult to genuinely impossible. Ask before you plan around it.
Whether you're keeping the tub. Tub-to-shower conversions change the drain position and often the trap. Worth deciding early rather than mid-demolition.
Shower valve type. A pressure-balancing or thermostatic valve prevents the temperature swinging when someone flushes elsewhere in the house. It sits inside the wall, so changing your mind afterward means opening tile.
Niche and bench positions. These interact with framing and with where the pipes can run. Coordinate before framing, not after.
Whether you want in-floor heat. The one upgrade people most regret skipping. It's straightforward while the floor is up and a significant job later. Radiant heating
Fixture selection. Wall-mounted taps, wall-hung toilets and freestanding tub fillers all need specific rough-in work. Choose the fixtures before the rough-in, not after — this is the single most common sequencing mistake in bathroom renovations.
What we do
Demolition-stage disconnection and capping · Moving and rerouting supply and drain lines · Rough-in to the agreed layout · Shower valve and pressure-balancing installation · Fixture installation — toilet, vanity, tub, shower, taps · Venting where a fixture moves · Permit and inspection · Final testing and commissioning
Working with your contractor
Most bathroom renovations involve several trades and the plumbing happens in two visits — rough-in before the walls close, then final fit-off after tile and paint. We coordinate with your GC on scheduling, and we attend the inspection.
If you don't have a GC and you're managing it yourself, tell us at the quote stage. We'll flag the sequencing you'll need to get right with the other trades.
Permits
Bathroom renovations generally require a plumbing permit where fixtures are moved or lines altered. Like-for-like replacement in the same position often doesn't. We'll tell you which yours is, and we pull it where required.
Unpermitted bathroom work is common and it surfaces at resale. It's not worth the saving.
