📞 (905) 261-9082A bathroom renovation involves updating or rebuilding some or all of the elements that make up a bathroom — tile, fixtures, vanity, tub or shower, flooring, lighting, and surrounding finishes. The scope can range from swapping out fixtures and tile in an existing layout to a full gut and rebuild from bare concrete and studs.
Water is the primary cause of structural damage in bathrooms. Failed tile grout, inadequate waterproofing behind a tub surround, or improperly sealed shower floors allow moisture to reach the framing and subfloor over time. By the time the damage is visible from the outside, it is often already significant. A bathroom renovation done correctly starts with proper waterproofing before any tile goes in — this is not a step to cut corners on.
Common triggers include tile that is cracked, stained, or deteriorating, grout that is failing or discoloured beyond cleaning, fixtures that are outdated or no longer functioning correctly, persistent moisture or mold issues, or a layout that simply does not work for your household. If your bathroom requires ongoing maintenance to stay presentable, or if you are actively avoiding using it, a renovation is worth considering.
Soft or spongy spots when you press on tile, grout that crumbles or falls out easily, tile that shifts or sounds hollow when tapped, discolouration on adjacent walls or ceilings, and persistent mold that returns after cleaning are all potential indicators of water damage behind the tile. These are assessed during the demolition phase of a renovation, and we let you know exactly what we find before proceeding.
We review the bathroom with you, discuss what you want to change, and identify anything behind the walls or under the floor that may need attention. You receive a clear written quote before work starts.
Everything that is coming out is removed carefully. We assess what is behind the walls and under the floor at this stage — so nothing surprises us once the project is underway.
Waterproofing is installed before any tile. Plumbing and electrical rough-in is completed at this stage. This is where a bathroom renovation is either done properly or not — and we do it properly.
Tile installation, vanity, fixtures, trim, and final finishes complete the project. We clean up thoroughly and walk through the finished bathroom with you before we leave.
A full gut renovation involves removing all existing finishes down to the studs and subfloor, assessing and repairing anything that needs attention, installing waterproofing, completing plumbing and electrical rough-in, and then rebuilding the bathroom from scratch. The result is a bathroom where you know exactly what is behind the walls, because your team put it there.
Timeline depends on the size of the bathroom, the scope of the work, and what is found during demolition. We provide a realistic timeline specific to your project when we quote it. Projects that uncover unexpected conditions behind the walls may require adjustments — we communicate those to you as soon as they are identified.
Plumbing and electrical work is included in our bathroom renovation scope where required. Fixture hookups, fan installation, lighting, and drain or supply rough-in are factored into the project.
Permit requirements depend on the municipality and the scope of work. Projects that involve plumbing changes or electrical updates may require permits. We walk you through what applies to your specific project during the quoting process.
