How Long Does a Bathroom Remodel Take From Demolition to Final Walkthrough?
Most people asking this question are looking for a number and they receive a range so broad as to be useless. Two to six weeks is the typical response, and it is true in the same way that a weather forecast for next week that includes every temperature from freezing to ninety degrees is accurate.
The reason for this is largely down to what happens before the demolition crew arrives, and this is an important nuance for anyone looking at bathroom remodeling quotes. Anyone who has seen multiple contractors for a similar scope of work will note that the time difference between bidders is usually explained in their assumptions about permits, materials and how quickly the homeowner will make decisions.
The Weeks Before Anyone Swings a Hammer
Design, selection and ordering usually take significantly longer than the work itself. Glass showers, tile, cabinets and fixtures all have lead times, and the glass is typically installed last, after the tile, which puts it towards the end of the timeline by default. One of the surest ways to blow a remodeling budget and schedule is to begin demolition before all materials have arrived, resulting in an extended and unproductive downtime for the contractor.
Permits and Inspections
A simple update to a bathroom’s cosmetics may not need a permit at all, so long as no fixtures are relocated and the work doesn’t alter the structure of the home in any way. As soon as rough plumbing, rewiring or structural alterations take place, however, permits must be applied for. The timeline for permits differs from city to city, but most require inspections at specific points in the process, namely plumbing and electrical rough-ins before closing walls back up, and additional inspections at other points later on. If an inspection fails, it may not be a major issue but the work will have to be paused until the problem is fixed and it has been resubmitted for approval.
Demolition: One to Three Days
The quick and gratifying part. This is the step at which the project’s costs and schedule begin to become less predictable, however, because it is at this stage that jobsite conditions are revealed. Water damage can be found behind the shower, rot can appear in the subfloor, galvanized supply lines may be discovered in place of copper, wiring may need to be replaced and asbestos or lead paint may be found in older structures. At this stage, a ten to twenty percent contingency for both time and money is not unreasonable.
Rough-In: Three to Seven Days
Plumbing and electrical work begins, and framing is altered or replaced to accommodate new fixtures. The waterproofing membrane, the most inconspicuous part of the bathroom, is also the most important, because if it is not installed properly, water damage will eventually appear years later in the ceiling of the room below. Inspection at this stage means that the schedule cannot move forward until the job passes.
Tile, and Why It Sets the Pace
Tile work is where a week can become two, and where a short job can turn long – mosaic, intricate patterned tiles, herringbone, large slabs and niches all extend the time required for the job and absorb scheduling pressure. In addition, there is no rushing the curing time of thinset between setting and grouting, and it is the step that gets skipped more often than any contractor will admit under pressure.
The Cost of Living Without the Room
Asking about the schedule is really asking about logistics, and the answer depends on how many bathrooms the house has. Being without one bathroom for two weeks is not the same as being without two, and it is reasonable to ask a contractor to identify specific days when the space is fit for limited use rather than completely unavailable. In some cases, especially when there is only one bathroom, a plumber can be persuaded to leave a functional toilet in place throughout much of the process.
Finishes and the Punch List
Vanities, toilets, fixtures, mirrors, lighting, paint and hardware are all installed over the course of approximately a week, and the glass shower door is delivered separately, usually a week or two later. Punch list items, the minor jobs that come up at final walkthrough, take another several days to complete and are the one task list in this entire process that most often gets rushed. It can be a good idea to walk the job with the contractor before final approval, checking that the door opens fully on the new flooring and that every light switch works correctly.
Conclusion: Two to Five Weeks on Site, Longer on Paper
A simple update to an existing bathroom that keeps plumbing in place takes two to three weeks on average, and significantly longer with a full gut and fixture relocation. Adding in the selection and ordering period before demolition begins makes for a two to three month time frame from initial consultation to final walkthrough. Much of that span is waiting rather than working, with no crew on site for long stretches at a time, and the jobs that finish closest to their projected completion dates are those that have all materials on-site before the start of demolition.
