Bathroom Renovation in Newmarket

Around 10-20% is normal, sometimes more where custom vanities or imported fittings must be ordered up front — in that case pay the supplier invoice share, not a round 50%. Hold 5-10% back until the room has been used for a week or two and the snag list (grout gaps, silicone, door alignment) is closed.

If the renovation strips the shower area back to the substrate, waterproofing must be redone — a failed membrane is the most expensive bathroom defect there is, because the fix means demolishing finished tiling. Several countries regulate wet-area waterproofing explicitly. Never let a contractor tile directly over an old or damaged membrane.

It can work on sound, well-bonded wall tiles and saves strip-out cost, but it fails on floors with movement, adds thickness that fouls doors and fittings, and hides the condition of the substrate and membrane. Most renovators strip back in wet areas — if a contractor proposes tile-over-tile in the shower zone specifically, treat it as a cost-cutting red flag.

A like-for-like refit usually needs no permit in Newmarket, but moving drainage, altering walls, or adding a new bathroom typically does under your local building rules — and electrical and plumbing work must be done by qualified or licensed trades in most countries. Ask your contractor to name the specific approval needed; see the country checklist on this page for what applies where you live.

Buying your own toilet, vanity, and taps gives price control; buying through the contractor makes them responsible for defects, wrong sizes, and delivery timing. A common middle path: contractor supplies everything built-in or warranty-critical (shower valves, waste, membrane), you supply visible items like mirrors and accessories. Whoever supplies an item owns replacing it if it arrives damaged.

Typical full renovations run CAD 12,000-28,000 with mid-range projects around CAD 18,000; budget refreshes start near CAD 5,000-8,000 and high-end or primary-bath projects reach CAD 40,000-70,000 in major metros. These track US Angi/HomeAdvisor figures adjusted to Canadian labour rates and CAD.

Yes — interior work is season-proof and many renovators discount January-March when exterior work stops. The main winter caveat is ventilation during tiling and curing; make sure the contractor plans for it rather than opening windows at -20°C.
