Bathroom Renovation in Newmarket: A Homeowner's Planning Guide

1. Start with how you use the room

Before thinking about tile, think about routines. Who uses this bathroom, and when? A main bathroom shared by kids needs durable surfaces, good storage and easy cleaning. An ensuite might be about a larger shower and a calmer feel. A bathroom for an aging parent may need a curbless shower, grab-bar blocking in the walls and a comfort-height toilet.

Write down three lists: what frustrates you about the current room, what you must have, and what would be nice to have. This becomes the brief for your contractor and keeps decisions focused when choices multiply.

2. Decide whether the layout stays or changes

The single biggest decision is whether fixtures stay where they are. Keeping the toilet, shower and vanity in their current locations usually keeps the project simpler, faster and more predictable. Moving them, for example turning a tub into a walk-in shower on another wall or relocating a toilet, means new drain and supply lines, sometimes changes to floor framing, and in most cases a building permit.

Neither option is wrong. A layout change can transform a cramped room. Just make the decision early, because it affects the permit, the schedule and the quote.

3. Permits in Newmarket

The Town of Newmarket issues building permits under the Ontario Building Code. As a general rule, cosmetic work and like-for-like replacements don't need a permit, while adding or altering plumbing, removing or changing walls, or creating a new bathroom generally does. The Town's Building and Renovating page is the place to confirm your situation, and the building department can answer specific questions.

Electrical work, such as new lighting circuits, heated floors or a new exhaust fan, falls under Electrical Safety Authority (ESA) rules and must be done by a Licensed Electrical Contractor. At BDF, plumbing and electrical work is completed through our licensed partner contractors, and we handle building permits when they're needed.

4. Don't skip what you can't see

The parts of a bathroom that matter most are hidden once the tile goes on:

• Waterproofing. Shower walls and floors need a proper waterproofing system behind the tile. Grout and tile alone aren't waterproof.
• Ventilation. An exhaust fan that's properly sized and vented outside (not into the attic) protects against moisture and mould.
• Subfloor and framing. Tile needs a stiff, flat base. Older floors sometimes need reinforcement or levelling.
• Existing damage. Slow leaks around old tubs and toilets are common. Good contractors explain up front how they handle surprises found during demolition.

5. Choose materials with lead times in mind

Vanities, custom glass shower doors and some tile can take weeks to arrive. The smoothest projects have major selections made and ordered before demolition starts, so the bathroom isn't out of service while you wait. A few practical tips:

• Pick tile in person and look at it in your own lighting if you can.
• Large-format tiles look clean but need a very flat substrate.
• Choose fixtures from mainstream brands so replacement parts are easy to find later.
• Order a little extra tile (ask your contractor how much) for cuts and future repairs.

6. What drives the cost

Every bathroom is different, which is why an on-site visit matters more than a phone quote. The main cost drivers are:

• Room size and the total area of tile
• Whether plumbing moves, and how accessible it is
• Shower type: a standard tub surround versus a custom tiled walk-in shower with glass
• Vanity, countertop and fixture choices
• Electrical upgrades such as lighting, heated floors or added outlets
• Repairs to hidden damage found during demolition

Ask for a written, itemized quote so you can compare contractors line by line. Under Ontario's Consumer Protection Act, home renovation agreements over $50 must be in writing (see your rights when starting home renovations).

7. Timeline: what to expect

A typical bathroom renovation moves through the same phases: planning and selections, permits if needed, demolition, rough-in work (plumbing, electrical, framing), inspections where required, waterproofing and tile, fixtures and finishing, and a final walkthrough. The overall length depends on scope and lead times. Your contractor should give you a written schedule before work begins.

8. Preparing your home

• If it's your only bathroom, plan where everyone will shower during the work.
• Clear the room and the path to it, and agree where materials will be stored.
• Talk about parking, working hours and how the crew will protect floors.
• Agree on one way to communicate (text, call or email) and how often you'll get updates.

Smaller project? Consider a remodel

Not every bathroom needs a full gut. A powder room or bathroom remodel, with a new vanity, toilet, flooring, lighting and paint, can refresh a room with far less disruption.
