Can I change the bathroom layout in my Vancouver condo or does strata restrict plumbing moves?

Yes, you can change the bathroom layout in your Vancouver condo, but you will need written strata council approval before any work begins, and plumbing moves add significant complexity, cost, and regulatory requirements. Most strata corporations in Metro Vancouver do not outright prohibit layout changes, but they impose strict conditions that effectively control what you can and cannot do.

The biggest factor limiting layout changes in a condo bathroom is the shared plumbing stack. In most Metro Vancouver high-rises and low-rises, the main drain stack is a vertical pipe running through every unit on the same line. Your toilet, shower, and sink all connect to this stack through horizontal drain lines that run through or under your concrete slab. Moving a toilet more than a few inches typically requires extending the drain line, which needs adequate slope (a minimum of 1/4 inch per foot for most drain sizes under the BC Plumbing Code). In a concrete slab building, this means either cutting into the slab or building up the floor to create enough height for the new drain run — both of which are expensive and require engineering assessment.

Moving a shower or bathtub is somewhat more flexible than moving a toilet because the drain size is smaller (typically 2-inch versus 3-inch or 4-inch for a toilet), but you still need proper slope to the stack connection. Moving a vanity sink is the easiest fixture relocation because the drain is small and supply lines are relatively simple to extend.

From a strata perspective, most bylaws require you to submit a detailed renovation plan that includes engineered drawings showing proposed plumbing changes, proof of contractor insurance (typically $2 million minimum liability), WorkSafeBC clearance for all trades, and a waterproofing plan. Many strata corporations also require a pre-renovation inspection of neighbouring units to document existing conditions, protecting both you and your neighbours from disputes about damage.

Costs for layout changes in a condo bathroom escalate quickly compared to a same-layout renovation. A standard condo bathroom renovation in Metro Vancouver without layout changes runs $15,000 to $30,000. Adding plumbing relocation can add $3,000 to $10,000 or more depending on how far fixtures move and whether the concrete slab needs cutting. You will also need a building permit from your municipality — permit fees in the City of Vancouver are typically $150 to $600 for bathroom work, with separate plumbing permits required for rough-in changes. A licensed plumber must perform all plumbing rough-in work per BC code.

There are practical limits even when strata approves your plan. You generally cannot move your bathroom to a completely different location in the unit because the drain stack location is fixed and running long horizontal drain lines under a concrete slab is impractical. You also cannot modify common property — the main stack itself, any structural walls, and the concrete slab between units are typically common property under the BC Strata Property Act.

Before committing to a layout change, have a licensed plumber assess the existing drain configuration and determine what is feasible within the physical constraints of your building. Get your strata's renovation bylaw package early in the planning process — some buildings have restrictions you will not discover until you apply. Budget an additional 10-20% above a standard renovation to account for the strata-related insurance, documentation, and restricted work hour requirements that slow the project timeline.
