Most straightforward bathroom renovations take between one and three weeks on site, but the honest answer depends on the size of the room, the state of what is behind the tiles, and how much you are changing. As plumbers working across Newcastle and the wider Tyne and Wear area, we see the full range, from four day refresh jobs to month long projects in older Victorian terraces. Here is a realistic breakdown so you can plan around it.
A like for like swap, where the new bath, basin and toilet go back in the same positions, is the quickest option. With no layout changes and walls in decent condition, this usually takes 4 to 7 working days including tiling and finishing.
A full renovation with a new layout, so moving the toilet, converting a bath to a walk in shower, or relocating the basin, typically runs 2 to 3 weeks. Moving soil pipes and hot and cold feeds adds first fix plumbing time, and everything after it has to wait for that work to be tested. Larger projects, such as knocking a separate WC through into the bathroom or fitting a wet room with full tanking, can stretch to 3 to 4 weeks.
The first day or two is strip out, removing the old suite, tiles and sometimes the floor. This is where surprises appear. In Newcastle's older housing stock, particularly Tyneside flats and pre war terraces, it is common to find perished lead or corroded galvanised pipework, rotten floorboards under the bath, or walls that need replastering before a tile will sit flat. Budget a contingency of 2 to 3 days for this.
Next comes first fix, routing new pipework and any electrics for showers, extractor fans or underfloor heating, followed by boarding, plastering and tanking wet areas. Plaster and tanking need drying time, which is why a bathroom can look untouched for a day or two even though the job is on schedule. Tiling and grouting usually take 3 to 5 days depending on tile size and how much of the room is covered. The final phase is second fix, connecting the suite, sealing, fitting the shower screen and accessories, then testing everything under pressure before handover.
The single biggest cause of overruns is not the trade work, it is materials. If a tile or a shower enclosure arrives damaged or a supplier has it on back order, the job can stall for a week. We always recommend having everything delivered and checked before strip out begins, so the room is only out of action while work is genuinely happening.
Coordination between trades matters too. A typical bathroom needs a plumber, a tiler and an electrician, and if they are booked separately by the homeowner, gaps between them add days. Using one firm that manages the sequence, or at least agreeing the full schedule before day one, keeps the handovers tight. Finally, anything discovered behind the walls, hidden leaks, asbestos backed boards in 1960s and 70s properties, or joists weakened by an old slow leak, has to be dealt with before work continues.
Make every product decision before work starts. Changing your mind about tiles mid job is the most common self inflicted delay we see. Confirm the suite, brassware, tiles, flooring and extractor fan, and have them on site and inspected before the old bathroom comes out.
Ask your installer for a written day by day schedule and a clear answer on who is doing the electrics and any certification. If it is your only bathroom, agree in advance when the toilet will be usable each evening, a decent installer will keep it connected overnight for most of the job, and plan for 2 to 3 days without a shower during tiling and sealing.
Usually the toilet can be reconnected at the end of most working days, but expect 2 to 3 days without it during strip out and second fix. You will be without a bath or shower for most of the project, so plan to use a second bathroom, family or a gym.
Some installers quote only the fitting days and assume walls and pipework are sound, while others build in preparation and contingency. Ask what the quoted duration includes, particularly replastering, first fix pipework changes and drying times.
Yes, typically 3 to 5 extra days. Relocating a toilet means altering the soil pipe run, which affects the floor, the external wall connection and everything sequenced after it, so it is worth deciding early whether the new layout justifies it.
