In Richmond Hill, a bathroom renovation typically runs somewhere between $7,000 for a same-footprint powder room refresh and $55,000+ for a full gut with relocated plumbing — and almost all of that spread comes down to one question: is anything moving, or is everything staying exactly where it already is? Here's how the real ranges break down, and what actually pushes a job from one bracket to the next.
What a real job costs, by scope
A like-for-like vanity swap and a full layout change with a relocated drain aren't the same project, and pricing them as one number is how homeowners end up with a quote that doesn't match reality:
- Cosmetic refresh / powder room (new vanity, toilet, tile, mirror, lighting — fixtures stay in their existing locations): typically $7,000–$18,000. This is also the tier that generally doesn't need a building permit, as long as no plumbing fixture is relocated and nothing structural changes.
- Mid-range renovation (new tub-to-shower conversion or walk-in shower on the existing footprint, updated vanity and tile, possibly new pot lights or a heated floor): typically $18,000–$30,000. A basic tub-to-shower conversion on its own — no plumbing moved — commonly runs $3,500–$8,500 depending on tile and glass; a fully custom version with a frameless enclosure and floor-to-ceiling tile can push $9,000–$15,000+ on its own.
- Full gut / layout change (moved plumbing fixtures, a new curbless shower with a relocated drain, or a structural change): typically $30,000–$55,000+. This is the tier where a permit, licensed plumbing and electrical work, and a scheduled inspection become part of the timeline, not just the budget.
All of these figures are pre-tax. Ontario's 13% HST on a $20,000 mid-range bathroom adds roughly $2,600 — worth confirming up front whether a quote is showing the number before or after tax.
Why Richmond Hill skews toward the full-gut bracket more than a newer build does
Richmond Hill has a larger share of older, established homes than a lot of the region's newer subdivisions, and those homes were often built with a single, small original bathroom footprint — sometimes with the tub, toilet, and vanity crowded into a layout that made sense for building code minimums decades ago, not for how a bathroom is actually used today. That's the practical reason a Richmond Hill bathroom project skews toward the mid-range or full-gut end of the range more often than a five-year-old build does: the honest answer to "can I just swap fixtures" is frequently no, because the existing layout itself is the problem, not the fixtures in it.
When Richmond Hill actually requires a permit
Replacing fixtures in their existing locations — a new toilet, vanity, tub, or shower installed where the old one sat — generally does not require a building permit. A permit is required once the work involves relocating a plumbing fixture, altering a load-bearing wall, or increasing electrical service capacity. A tub-to-shower conversion that keeps the drain in the same spot typically stays permit-exempt; move that drain, and it doesn't.
Where a permit is needed, the City of Richmond Hill prices house permits based on the construction value of the work rather than a flat per-square-metre fee: on its published schedule, a project with a construction value up to $10,000 runs a flat $80, and the fee then rises by $6 per $1,000 of value above $10,000 up to $50,000 — so a mid-range bathroom with a declared construction value around $20,000 lands near a $140 permit fee, before HST. Fees are indexed annually by the province's building construction price index under Ontario Regulation 425/24, so expect the exact amounts to move each January. Applications and payment go through the City's online ePay system with a Connect Richmond Hill account, or in person at City Hall. Ontario's Building Code Act sets a statutory maximum of 10 business days for the City to decide once an application is complete — but an incomplete submission resets that clock, so budget more like two to four weeks in practice before demolition starts.
One detail that catches homeowners even on permit-exempt jobs: new pot lights, a heated floor, or a new electrical circuit require notification to the Electrical Safety Authority regardless of whether the City requires a building permit for the rest of the work. That's a separate process from the municipal permit, and it's easy to assume it doesn't apply just because the building permit doesn't.
What actually drives the price
The fastest way to know which bracket a Richmond Hill project actually falls into is to ask directly: is any plumbing fixture moving, is any electrical work involved, and is the quote before or after HST. Those three answers explain most of the gap between a $10,000 refresh and a $40,000 renovation — far more than which contractor does the work.
