Bathroom Renovation / GTA

Bathroom Renovation in Mississauga

Spa-inspired bathroom renovations in Mississauga, ON. Serving Port Credit, Streetsville, and Lorne Park, and the wider GTA area.

Mississauga prices bathroom-scale interior alteration work at $6.84 per square metre against a $244 minimum, and each plumbing fixture reviewed separately at $42.23, the highest per-fixture rate of any city we build bathrooms in. A standard three-fixture bathroom, a toilet, a sink, and a tub or shower, adds roughly $127 in plumbing review fees on top of the base permit before any structural change is even considered. Relocating a fixture, opening a wall, or recessing a subfloor for a curbless shower all push the job into that same structural review Mississauga applies to any interior renovation.

Mississauga has the lowest share of pre-1960 housing of any city in our service area, just over 7 percent, with half the city's dwellings built between 1961 and 1990 during its postwar suburban boom. A bathroom from that era usually has copper or early aluminum supply lines rather than the galvanized pipe common in an older city, and a poured or block foundation, but its shower wall is still very likely cement board or plain gypsum board standing in for a real waterproofing membrane. We check that wall assembly on every Mississauga renovation before deciding what gets reused and what gets rebuilt from the studs out.

Spa-inspired bathroom renovations in Mississauga

We renovate bathrooms and ensuites across Mississauga with walk-in showers, freestanding tubs, heated floors, and premium tile, from Port Credit to Streetsville, and every wet wall gets a genuine waterproofing membrane rather than a board mistaken for one. Cement board resists incidental moisture far better than drywall, but water can still reach the framing behind it unless a membrane is installed over or behind the board, and that membrane, not the board, is what actually stops water at the source. Old gypsum board and moisture-resistant "greenboard" have no place behind a Mississauga shower wall, whatever the scope of the job.

Mississauga reviews each plumbing fixture in a bathroom permit at $42.23, the highest per-fixture rate of any city we build in, on top of a base interior-alteration fee of $6.84 per square metre and a $244 minimum. A standard three-fixture bathroom, a toilet, a sink, and a tub or shower, adds roughly $127 in fixture review fees alone. Relocating a tub or toilet, or recessing a subfloor for a curbless shower, pushes the job into the same structural review, since the floor has to slope continuously toward the drain before the finished surface goes down. We also frame in grab bar blocking on every full renovation regardless of the client's current needs, since it costs almost nothing while the wall is open.

Condo bathrooms in Mississauga

Mississauga's towers, around City Centre and along the lake, make condo bathrooms a large share of the work here. Before demolition the condo board or property manager normally wants a written description of the scope, proof of the contractor's insurance, and the dates trades will be in the building. Water is the board's real worry, since a leak lands in the suite below, which is one more reason the membrane behind the shower matters.

Plumbing and electrical inside a condo stay within the unit's own walls. The shared stack fixes where the toilet and shower drain can sit, and a new heated floor or extra lighting circuit has to fit the suite's existing electrical panel, so we confirm both before the layout is drawn.

Glass is usually the final piece on a Mississauga job, since a frameless enclosure can only be templated once the shower base and walls are genuinely finished, then built to that measurement.

Postwar suburban stock like this turns up again further along the lake, and how a 1970s wall assembly differs from a 1980s one is worked through under bathroom renovation cost in Toronto and bathroom renovations in Oakville.

I got my kitchen renovated by these guys and honestly, I’m really happy with how it turned out. The price wasn’t the cheapest, but it also wasn’t crazy expensive, and after seeing the final result, I feel like it was totally worth it. They did a really good job and paid attention to the small details. Everything came out better than I expected, and my kitchen looks completely different now. They were easy to deal with, showed up when they said they would, and finished the work properly. Overall, really good experience. I would definitely recommend them to anyone looking to get their kitchen or other renovation work done.

Bathroom Renovation in Mississauga, answered.

Why is my Mississauga bathroom permit's plumbing fee so high?

Mississauga reviews each plumbing fixture at $42.23, the highest per-fixture rate of the cities we build in, so a standard three-fixture bathroom adds about $127 to the base permit.

What's the base permit fee for a Mississauga bathroom?

Interior alteration work is priced at $6.84 per square metre against a $244 minimum, before the separate plumbing fixture fees are added on top.

Is cement board the same as waterproofing?

No. Cement board resists moisture but isn't waterproof by itself, water can still reach the framing behind it unless a membrane sits over or behind the board.

What actually drives up the cost of a curbless shower?

The floor comes down before the walls do. Lowering the subfloor at framing stage lets the finished floor pitch continuously to the drain, and that early structural work, not the tile choice, is the real cost driver.

Can you convert a tub into a walk-in shower?

Yes, tub-to-shower conversions are one of our most common Mississauga projects, including curbless and frameless glass options built on a proper waterproofing system.

What does a bathroom renovation cost in Mississauga?

See the pricing table above. As a GTA city, Mississauga bathrooms typically land toward the top of each range, especially on a full gut with new plumbing.

How long does a full bathroom renovation take in Mississauga?

Plan for four to six weeks on site. Waterproofing cure time, tile and grout cure, and custom glass templated after the shower is finished all add real days that labour alone can't compress.
