How long does a full bathroom renovation take in Saint John New Brunswick?

A full bathroom renovation in Saint John typically takes 2-4 weeks from demolition to completion, though complex projects involving layout changes, plumbing relocation, and custom tile work can run 4-6 weeks. The timeline is determined by the scope of trades involved, permit inspection scheduling, material lead times, and how many surprises emerge once walls come down.

The standard sequence for a full bathroom gut renovation goes like this: demolition and disposal (2-3 days), rough-in plumbing (2-3 days), rough-in electrical (1-2 days), TSANB rough-in inspections (which need to be scheduled and can add 2-5 business days of waiting time), substrate installation and waterproofing (2-3 days), tile installation (3-5 days depending on complexity), vanity and fixture installation (1-2 days), finish electrical (outlets, fan, lighting) and final electrical inspection (1-2 days), paint and trim (1-2 days), and final plumbing connections and cleanup. When you layer in the mandatory inspection hold points and the reality that trades often can't be on-site back-to-back without gaps, a well-coordinated project hits 3 weeks; a less-coordinated one hits 5-6 weeks.

Permit timing is a real factor in Saint John. Building permits for bathroom renovations that involve plumbing, electrical, or structural changes must be obtained from Saint John's building inspection department before work begins. Saint John, like most NB municipalities, has reasonable permit turnaround times — typically 1-2 weeks for straightforward bathroom projects — but that timeline needs to be built into your project schedule, not bolted on as an afterthought. Your contractor should be coordinating the permit application as part of their pre-construction process.

Material lead times can significantly extend the timeline if you choose items that aren't stocked locally. Stock tile from a Saint John supplier can be on-site within days; custom-ordered tile from a specialty supplier may take 4-8 weeks. Prefabricated vanities from big-box stores are usually available within a week; semi-custom or custom-ordered vanities often take 4-8 weeks. If you're ordering anything custom — cabinetry, special-order fixtures, imported tile — order it before demolition begins so materials are ready when the trades are.

Saint John's older housing stock is a wildcard in any bathroom timeline. The city has a significant inventory of Victorian and early 20th century homes, particularly in the South End and Uptown neighbourhoods, where opening bathroom walls commonly reveals knob-and-tube wiring that can't legally be covered without upgrading, galvanized plumbing pipes that are too corroded to connect new fixtures to without replacement, or subfloor rot from decades of minor moisture infiltration. Budget time and money for these discoveries — a realistic contingency is 15-20% of the project budget and 1-2 extra weeks on the schedule.

From a seasonal perspective, bathroom renovations run year-round in NB since it's interior work. However, Saint John's Maritime climate means that even in January, opening exterior bathroom walls for insulation upgrades can expose cavities to near-zero temperatures — experienced local contractors know to sequence this work to minimize the exposure window and have heating available during wall work. Material deliveries during winter also need consideration — tile and grout need to be stored in a temperature-controlled space before installation, not sitting in a cold truck or unheated garage overnight.

The most reliable way to get an accurate timeline in Saint John is to have your contractor develop a written schedule with trade sequencing and inspection hold points built in before signing a contract. A contractor who says "four weeks, no problem" without ever having opened your bathroom walls is making a promise they can't fully keep. A contractor who says "we plan for three weeks but we're allowing four given the age of your home and the TSANB inspection scheduling" is being honest with you.
