Most people asking this question have already pictured the finished room. What they want to know is how many mornings they will be brushing their teeth at the kitchen sink. For a straightforward like-for-like bathroom swap in a Glasgow home, you are typically looking at 7 to 10 working days on site, though flats, wet rooms and structural changes can push that to three weeks or more.
A full bathroom replacement in a typical Glasgow property, where the bath, basin and toilet stay roughly where they are, usually runs 7 to 10 working days. That is calendar time on site, not hours worked, because tiling adhesive, grout, silicone and paint all need drying time that cannot be rushed without the finish suffering.
The stages overlap less than people expect. One trade often has to finish and dry before the next can start, which is why a job with only four or five days of actual labour still occupies a fortnight of your calendar.
Tenement and older sandstone properties are the biggest variable in this city. Once the old suite is out, it is common to find cast iron soil stacks, lead or old copper pipework, timber floors that have been notched to death by previous work, or lath and plaster walls that will not take a tiled surface without being boarded out first. Each of these adds a day or two and cannot honestly be priced or scheduled before the strip out.
Moving the toilet is the single change that most often extends a timeline. Soil pipe routes in flats are shared and often run through a common close or down an external wall, so relocating a WC can mean coordinating with a factor, and in some cases with neighbours. Allow extra time for that conversation before work starts, not during it.
Wet rooms are also slower than a standard refit. Forming the fall in the floor, laying the tanking membrane and letting it cure properly before tiling adds roughly three to five days compared with fitting a shower tray.
This is usually the real question. The toilet is typically out of action from the strip out until second fix, so around 5 to 8 days in a standard job. Where a property has only one bathroom, it is often possible to refit the WC temporarily at the end of the first day so it is usable overnight, though this depends on the pipework and is not always practical once floors are up.
Showering is the longer gap. Between the strip out and the sealed, cured shower enclosure, expect 8 to 12 days without one. It is worth arranging a gym, a family member nearby or a neighbour in the same close before the job begins rather than improvising in week two.
Delays are far more often about decisions and deliveries than about labour. Tiles in particular catch people out: a discontinued line or a special order can add two weeks on its own, and the job cannot proceed past first fix without them.
Having everything on site before day one is the single most effective thing a homeowner can do.
Yes, a like-for-like refit in a straightforward property can be done in five working days if all materials are on site and no problems appear behind the old suite. It leaves very little slack, so any surprise in the pipework or floor will push it past the week.
Only a little. A compact Glasgow bathroom has the same sequence of stages and the same drying times, and tight spaces often slow tiling and fitting down rather than speed them up. Expect to save perhaps a day, not half the job.
You do not need to be there all day, but being reachable matters. Decisions about unexpected pipework, tile setting out or the height of fittings come up mid job, and a quick answer keeps the schedule intact.
