From Mission City heritage homes with knob-and-tube and galvanized supply lines to newer Cedar Valley primary ensuites and lakeside Hatzic properties, Mission bathrooms ask different things of a rebuild. We plan each one for the house in front of us, with Red Seal plumbers on every rough-in and sheet-membrane waterproofing on every shower.

Quick Answer
Bathroom renovations in Mission run $15K to $30K for a cosmetic refresh, $30K to $50K for a standard rebuild, and $50K to $75K for a custom ensuite with walk-in shower and heated floors. Premium ensuites reach $75K+. Sheet-membrane waterproofing on every shower, Red Seal plumbers on every rough-in, District of Mission permits handled in-house. Typical timeline: 3 to 8 weeks. Line-item quotes, no blanket allowances.
Bathrooms in Mission
Mission carries a wider spread of housing eras than its population suggests. The heritage core climbs the hillside above the Fraser with pre-war and post-war homes. Cedar Valley and Silverdale built out heavily on slope through the 1980s and 1990s. Hatzic Lake has lake-adjacent and foreshore properties. Stave Falls, Hatzic Prairie, and the rural east read fully agricultural. The bathroom scope changes meaningfully by neighborhood.
In the Mission City heritage core, the bathroom conversation usually starts behind the wall. Knob-and-tube wiring still in service in some homes, galvanized supply lines, original cast-iron drains, and lath-and-plaster walls all show up regularly. A serious bathroom rebuild here is also a mechanical upgrade. Our Red Seal plumbers and electricians pull the trade permits directly through Technical Safety BC and bake that scope into the quote rather than discovering it at demo.
In Cedar Valley, Silverdale, and along the lake corridor, the homes are newer and the bathrooms we replace are typically builder-grade tub surrounds, stock vanities, basic tile, and minimum-spec fans aging out of their first cycle. Plumbing and electrical bones are usually good. Scope here focuses on custom showers, heated floors, freestanding tubs, primary ensuite layout reconfigurations, and tile and fixture upgrades rather than mechanical rework.
A bathroom is the smallest room in the house and the one with the most ways to fail. Plumbing, electrical, waterproofing, tile, ventilation, framing, and finish trades all converge in a 40 to 80 square foot space. At Huntley, our framers, Red Seal electricians, and Red Seal plumbers work for the same company. The rough-in coordination meeting happens at the job site on a Tuesday morning, not on a three-way phone call between separate trades.
The Mission bathroom context
Mission is not one housing market. The plumbing behind a 1940s Mission City heritage bathroom is not the same as a 1995 Cedar Valley ensuite or a Hatzic Lake foreshore project. We plan each one for the house in front of us.
Pre-war and post-war homes climbing the hillside above the Fraser. Bathroom renovations in this stock almost always combine the waterproofing rebuild with mechanical work behind the wall: knob-and-tube wiring still in service in parts of some homes, galvanized supply lines, original cast-iron drains, and lath-and-plaster walls. We open the access at site visit where possible and price the full scope honestly upfront.
Built out heavily through the 1980s and 1990s on graded hillside lots. Walk-out basements, retaining walls, and drainage routing all complicate bathroom additions and basement ensuites. Drain venting routes have to respect slope and existing site grading. We plan slope and drainage interactions at quote stage rather than discovering them during rough-in.
Lake-effect humidity is a real factor on Hatzic Lake bathrooms. Properly sized and vented exhaust fans, dehumidification planning, and finish-grade selection (cabinet materials, tile choice, paint type) all need to account for it. Foreshore properties also sit inside riparian assessment areas where exterior work close to the water can trigger District of Mission and provincial review.
Rural Mission bathrooms bring wells, septic, propane, and ALR considerations into every quote. Septic field capacity is the constraint that decides whether an ensuite addition is feasible. Wells need flow-rate verification before adding a rain head or high-flow tub filler. ALR rules restrict accessory dwelling and footprint changes on agricultural-zoned property. We assess these at site visit.
What's in scope
Demolition through final walkthrough. Plumbing, electrical, waterproofing, tile, and finish all handled by the same team under the same project manager. One point of contact. One company accountable.
Demolition through finish. New plumbing rough-in, waterproofing, tile, fixtures, vanities, ventilation. Ensuites, main baths, powder rooms, and second-storey bathrooms with structural considerations planned in.
Curbless showers with proper slope, bench seats, recessed niches, multi-head setups, linear drains, heated floors. Full waterproofing systems installed to the membrane manufacturer spec. Not a liner and hope.
Fixture relocations, drain routing, shower valve upgrades, pressure-balance and thermostatic valves, water line replacements from galvanized to PEX or copper. All handled by our Red Seal in-house plumbers.
GFCI outlets, dedicated heated-floor circuits, proper fan venting to the exterior, vanity lighting on dimmer, service upgrades where older Mission bathrooms need them. Our Red Seal electricians on every rough-in.
Schluter, KERDI, or equivalent sheet-membrane waterproofing systems installed per manufacturer spec. Tile, grout, sealing, niches, accent walls, shower pans. Waterproofing is checked and photographed before tile goes on.
Stock, semi-custom, or fully custom vanities. Quartz, stone, or solid-surface tops. Undermount or vessel sinks with proper plumbing chase planning. Integrated storage, soft-close hardware, wall-hung options.
Proper exterior-vented fans sized to the bathroom volume (per BC Building Code), humidistat or timer switches, make-up air where a fan is high CFM. Especially important on Hatzic Lake humidity-prone properties.
Curbless showers, grab bars, wider doorways, comfort-height toilets, lever fixtures, walk-in tubs. Accessibility planned to look like a modern bathroom rather than institutional.
Five trades. One company.
One schedule that holds.
Carpenters, Red Seal electricians, and Red Seal plumbers under the same payroll. The rough-in coordination meeting happens at the job site, not on a three-way phone call. That is why our bathrooms are still performing a decade in.
How a Huntley bathroom gets built
We come to your Mission home, measure the bathroom, look behind the access panel or in the basement at the existing plumbing, and discuss what you want changed. We tell you honestly whether the current layout can support the bathroom you have in mind or whether walls or fixtures need to move.
Tile selections, fixture selections, vanity grade, shower configuration, glass details. Everything spec-ed before contract. You see a line-item quote with every trade and every finish priced. No vague allowances that grow into change orders later.
Permits pulled where the scope requires them. We have run building permits through District of Mission Building Department often enough to know what they want to see at intake. Fixtures and tile ordered early so lead times do not trip the schedule. Custom shower glass templated after the tile is in.
Demolition, framing adjustments, new plumbing rough-in, electrical rough-in, inspections, waterproofing install, shower pan build. We pressure-test plumbing and water-test waterproofing before tile covers anything.
Tile install, grout, fixture set, glass install, vanity and top set, accessories mounted, paint touch-up. We walk every surface with you and resolve any deficiencies before handover. The 12-month Huntley Workmanship Commitment begins from the day you take the keys back.
Honest numbers
Most contractors will not publish real numbers. We will. These are typical Mission project ranges by scope tier. Mission City heritage bathrooms often run higher within these tiers because of rewire or replumb work. Your final number is line-itemed after a site visit.
Refresh
$15K – $30K
Same layout. New vanity, toilet, faucet, lighting, tile if needed, paint. Existing tub or shower stays. A clean cosmetic update without rebuilding the waterproofing layer.
Standard rebuild
$30K – $50K
Full demo, new tile shower or tub surround with proper sheet-membrane waterproofing, new plumbing fixtures, vanity, flooring, lighting, exhaust fan. Same general footprint. The most common scope for a Mission main bathroom.
Custom / ensuite
$50K – $75K
Custom walk-in shower (curbless, bench, niches, linear drain, glass enclosure), heated floors, freestanding tub, higher-grade fixtures, quartz counters, custom vanity. Primary ensuites in Cedar Valley and Silverdale typically land here.
Premium
$75K – $150K+
Wet-room designs, premium stone or slab walls, designer fixtures, integrated lighting, steam showers, heated benches and niches, and often work that expands into a walk-in closet or adjoining bedroom.
Typical Fraser Valley ranges, not quotes. Actual pricing depends on scope, site conditions, tile and fixture selections, and whether the layout changes. We give you a real line-item number after the site visit.

What to watch for
Bathroom surprises are almost always the same handful of issues tied to housing era, hidden plumbing, or waterproofing shortcuts. We flag these at the site visit rather than at rough-in. Here is what we look for on Mission homes.
Pre-war and immediate post-war homes in Mission City heritage core frequently have knob-and-tube wiring still in service in parts of the home. New bathroom GFCI outlets, heated-floor circuits, and properly vented exhaust fans cannot tie into knob-and-tube, and insurers increasingly require active K&T to be replaced. We identify K&T at the site visit and price the localized rewire (or whole-home rewire if scope warrants) into the quote rather than discovering it once the tile is off the wall.
A tile shower looks finished long before it actually is. The expensive part, the part that prevents catastrophic failure, is the waterproofing membrane underneath. Done right, it is a sheet-membrane system (Schluter KERDI or equivalent) installed per manufacturer spec, with the matching pan, drain, curb, and seam treatments. Done wrong, it is tar paper, liquid membrane brushed on too thin, or no membrane at all. Five years in, the difference is a $4K bathroom rebuild that becomes a $25K rebuild because the subfloor and joists below have rotted. We use sheet membrane on every shower, photographed before tile goes on.
BC Building Code sets minimum CFM for bathroom exhaust fans by room volume, but Hatzic Lake humidity demands more than the code minimum. Undersized fans, or fans vented into the attic instead of through the roof, lead to mold inside wall cavities within three to five years on lake-adjacent properties. We size the fan correctly to the bathroom volume and the local humidity context, vent it properly to the exterior, and recommend humidistat switches.
Stave Falls, Hatzic Prairie, and Mission acreage properties typically run on private septic systems sized for an estimated daily load. An ensuite addition that adds toilet, shower, and sink fixtures where none existed can push a marginal septic system over capacity. We verify septic capacity at site visit and coordinate with septic designers where the project requires field expansion before bathroom scope is finalized.
