Bathroom Renovations in Langley, BC

A bathroom-only job can be as small as one tub replaced with a shower. A larger one can cover every bathroom in a whole-home renovation. We take both, and a single bathroom goes through the same steps as a whole-home job: a site visit, a scope of work, permits, inspections and trades booked in order.

We run the job from demolition to the last piece of trim. A licensed plumber does the plumbing, because the Township asks for the plumber's trade qualification number and business licence number on a plumbing permit. Electrical work is done by a licensed electrician under a Technical Safety BC permit. We book the inspections, and the next trade starts only after an inspection passes.

The Township's plumbing permit guide (January 2025) lists the small jobs that need no plumbing permit: repairing or replacing faucets, replacing a fixture that stays in the same place, fixing a leak or a blocked drain, and replacing a hot water tank.

A plumbing permit is needed to install, change or upgrade any part of the plumbing system, to add fixtures, or to replace water lines. The Township's renovation guide also lists building permit work that covers a bathroom with a new layout: altering or renovating a building, and installing new plumbing fixtures or re-arranging piping. When a building permit covers the job, the plumbing is usually included on it.

A plumbing permit application needs a scaled floor plan that marks every fixture added, removed or replaced. Applications go in online. A building permit application also needs a title search no older than 30 days. The Township does not publish how long it takes to issue a permit.

Electrical and gas permits are separate. The Township sends owners to Technical Safety BC for those. Technical Safety BC says a licensed contractor can replace existing switches, receptacles or thermostats without a permit. Replacing light fixtures, or installing or moving switches and outlets, needs a permit. A licensed contractor applies for it on your behalf. Owners of a strata unit or a duplex, and people who run a business from home, cannot get a homeowner permit and must hire a licensed contractor.

The City of Langley has its own Building Division, at 20399 Douglas Crescent. Its guide for altering a single-family house says a permit is needed to remove, move, alter or build interior walls and to install new plumbing fixtures. It also lists work that needs no permit, such as replacing cupboards and painting.

The City's title search must be no older than 48 hours, where the Township allows 30 days. If the house is over 30 years old, or the renovation is worth more than $100,000, the City's Engineering Department decides whether the existing utility connections need upgrading. And sanitary lift pumps are not allowed in the City's single-family areas. A pump is what lets a toilet or shower sit lower than the sewer line, so before we design a new basement bathroom in the City, we check that its drains can reach the sewer by gravity.

Every trade working in the City needs a valid City business licence. Electrical permits come from Technical Safety BC, as in the Township.

Large parts of Langley have no sewer. The Brookswood-Fernridge plan says most of that area runs on private on-site systems. The Fort Langley plan says homes north of the railway tracks are on the sewer and the rest of the village uses septic. The Township's community plan says rural areas are served by on-site systems.

When a Township building permit is applied for on a septic property, a Registered Onsite Wastewater Practitioner (ROWP) has to complete one of two documents: a Fraser Health record of filing to build or alter the system, or a Building Permit Referral Form when the system needs no work. The Township will not issue the permit until the record of filing is in. For a new suite, the ROWP also seals the suite floor plan.

Under BC's Sewerage System Regulation, only an authorized person, meaning a ROWP or a professional engineer, may build or alter a septic system, or an owner working on their own land under that person's supervision. Fraser Health asks that person to confirm the system's daily design flow when it is repaired. Any filed work must be finished within two years of the date Fraser Health stamps on the filing.

In practice, we bring the ROWP in before the bathroom is drawn. If the system can take the new fixtures, the referral form goes in with the permit. If it cannot, the septic work is designed and filed alongside the renovation, so the Fraser Health filing is ready when the Township asks for it.

The Township's renovation guide says a hazardous material survey and a Notice of Project may be required for homes built before 1990. WorkSafeBC says asbestos was widely used in BC building materials until the early 1990s, that it has been found in over 3,000 household materials, and that a homeowner needs the home tested before a renovation or demolition starts.

The Township's community plan says Brookswood and Aldergrove grew fast in the 1970s, so houses from that decade fall inside the pre-1990 line. WorkSafeBC says only qualified professionals can remove asbestos, and abatement contractors must be licensed in BC. If a test finds asbestos, their work is booked before our demolition, and its cost is known before the job starts.

In the Township, every secondary suite needs a building permit, including the suite's bathroom. The Township's suite guide limits a suite to 120 m² of finished living area, not counting shared laundry or shared exits. The suite drawings must show all plumbing fixtures, the hot water tank, and the heating and ventilation details. The Township's zoning allows one secondary suite per house, and on farmland in the Agricultural Land Reserve the suite must be fully inside the main house.

Suites in the Township also carry a yearly Secondary Suite Infrastructure Fee on the property tax bill: $145 in 2026 and after. In the City of Langley, a secondary suite can be up to 100 m² and no more than 40% of the building, and the owner must live on the lot.

A suite bathroom on septic goes through the ROWP steps above, with a sealed floor plan. The suite drawings must also show the fire separation between the suite and the shared areas, so we plan the bathroom's drain route and fan duct together with it.

For owners who want to stay in their home as they get older, the common bathroom changes are a walk-in or step-free shower in place of a tub, a fixed or fold-down shower seat, grab bars, a handheld shower head, lever faucets and a raised toilet. When walls are open, we add solid wood backing where grab bars may go later, so they can be screwed in without opening the wall again.

Two programs can help with the cost. The federal Home Accessibility Tax Credit lets a person who is 65 or older, or who qualifies for the disability tax credit, claim up to $20,000 a year of eligible renovation expenses that make the home safer or easier to get around. Some relatives can make the claim for them. Paid work by a professional, such as a plumber, electrician or carpenter, generally counts.

BC Housing's BC Rebate for Accessible Home Adaptations (BC RAHA) is for low-income households where someone has a permanent disability or loss of ability. Its schedule lists a rebate of up to $9,100 to turn a tub into a walk-in or wheel-in shower, which needs an assessment by an occupational or physical therapist. The lifetime limit is $20,000 per household. The schedule says work done before BC Housing's written approval is not eligible, except some emergency work before a hospital release, and approved work must be done within 180 days. Apply before we book the job.

The Township's guides say work must not go past an inspection stage without clearance. The City's guide lists a rough plumbing inspection once the drains, vents and water piping are in, and says plumbing that will be covered by concrete must be inspected and accepted first.

Tell us at the first visit if you plan to live in the house during the work, and how many bathrooms it has, so we can plan for the days a bathroom is out of use.

We do not publish price ranges for bathrooms, because we have found no credible, named source for them. We price each one from a site visit and a scope of work. These are the things that move the number:
