Pipe Relocation & Rough-In Work

Changing the layout of a kitchen or bathroom almost always requires relocating water supply pipes, waste lines and sometimes gas lines. This is the stage where experience and precision matter most. Plumbway Ltd handles all rough-in plumbing, including moving hot and cold water pipes to accommodate new sink, shower or bath positions, rerouting waste and drainage to suit updated floor plans, and installing or extending gas lines for cooktops, gas fires or continuous-flow water heaters. We work closely with your builder to coordinate pipe installation with framing, flooring and waterproofing schedules so there are no delays on site. All work is completed in full compliance with the New Zealand Building Code and signed off for council inspection.

Fixture Installation & Fitout

The fitout is where your renovation vision comes to life. Plumbway Ltd installs all plumbing fixtures including kitchen sinks, tapware and mixer taps, dishwasher connections, bathroom vanity basins, toilets, showers, freestanding baths and heated towel rails. We work with all major New Zealand fixture brands and can advise on the best options for water efficiency and durability. For kitchen renovations, we also connect gas hobs and ensure rangehood ducting is properly vented. Our attention to detail and tidy workmanship means your new kitchen or bathroom will look and perform exactly as planned.

Frequently Asked Questions

Do I need a building consent to move plumbing in a renovation?

It depends on the scope. Moving waste pipes, installing new drainage connections, or relocating a toilet or basin typically requires a building consent from your local council. Like-for-like replacements (such as swapping a toilet for a new toilet in the same position) generally don't require consent. We can advise on your specific project and help you understand what's required before work begins.

Can you help plan the plumbing layout for a bathroom renovation?

Yes. We can advise on the most practical and cost-effective plumbing layout for your renovation — whether you're doing a complete bathroom gut and redesign or a simpler fixtures-only update. Moving plumbing costs more than keeping it in place, so we'll help you understand the trade-offs so you can make an informed decision with your designer or builder.

Do you work alongside kitchen and bathroom renovation companies?

Yes. We regularly work as the plumbing subcontractor for kitchen and bathroom renovation projects managed by builders, designers or renovation companies. We're experienced at fitting plumbing work around other trades and hitting programme milestones. We can also work directly with homeowners who are managing their own renovation.

What does renovation plumbing involve?

Renovation plumbing typically includes: disconnecting and removing existing fixtures, capping or relocating existing supply and waste pipes, installing new supply lines and waste connections in the new layout, installing and connecting new fixtures (shower, bath, basin, toilet, tapware, kitchen sink, dishwasher connection), and arranging any required council inspections for consented work.

Can you replace an old hot water cylinder as part of a renovation?

Yes. Renovations are a great time to replace an aging hot water cylinder — especially if you're upgrading a bathroom or kitchen. We can install a new electric, gas or continuous flow hot water system, and advise on the best option for your household size and budget. If you're switching from electric to gas (or vice versa), we'll manage the full changeover.
