Basement Suite Plumbing in BC
Basement suite additions are one of the most popular renovation projects across the Lower Mainland, especially in Surrey, Langley, Abbotsford, and Maple Ridge. A legal basement suite requires a full bathroom, kitchen, and laundry plumbing that meets BC Building Code. We handle all of it — from cutting into your existing drain system to installing all the rough-in and fixtures your suite needs to pass inspection.
Working with Your Renovation Team
We work alongside general contractors, designers, and other trades every day. We can review your renovation plans, flag any plumbing concerns before walls are closed, and communicate our scope clearly to everyone involved. If you don’t have a general contractor yet, we can also work directly with you as the homeowner on a managed basis.
Permits for Renovation Plumbing
Any plumbing work that involves adding, moving, or altering drain or supply lines requires a permit in BC. This includes adding a bathroom, moving a kitchen sink, or roughing in a new ensuite. We pull all required permits and ensure our work is inspected and approved so you have a clean record for resale.

Frequently Asked Questions
Find quick answers to the most common questions about our plumbing services, pricing, and availability.
Do I need a plumber for a bathroom renovation?
Yes, if any supply or drain lines are being moved, added, or altered. Even if you’re keeping fixtures in the same location, a licensed plumber should disconnect and reconnect to ensure everything is code-compliant and leak-free.
When does the plumber come in during a renovation?
Plumbing happens in two phases: rough-in (before walls are closed) and final (after tile and drywall, to install fixtures). We coordinate our schedule with your renovation timeline.
How much does bathroom rough-in cost in BC?
A standard bathroom rough-in typically costs $1,500–$4,000 depending on complexity, the number of fixtures, and whether any drain relocation is needed. We provide detailed quotes based on your renovation plans.
Can you add a bathroom to a basement suite?
Yes. We do basement suite plumbing regularly across the Lower Mainland. We’ll assess whether a sewage ejector pump is needed and handle all rough-in and permits for a code-compliant suite bathroom.
Do you work with general contractors or just homeowners?
Both. We work seamlessly with GCs and design-build teams as well as directly with homeowners managing their own renovation projects.
