The duration of a bathroom renovation depends on factors like the size of the bathroom, the complexity of the project, and how well the preparation is planned. In this blog, we’ll break down the general timelines for different bathroom sizes and what can impact the overall duration. This will help you better understand the process and plan accordingly.

Bathroom Renovation Timeline by Size

The time it takes to renovate a bathroom varies largely depending on the size and scope of the project. Below is a breakdown of the typical time frames based on different bathroom sizes.

Small Bathroom (2-3 weeks)

Plumbing and Electrical Work (2-4 days): If you’re not making major changes to the layout, such as relocating plumbing, this can be done within a few days. More complex changes may take slightly longer.

Installing Fixtures and Finishes (3-4 days): Once plumbing and electrical work are complete, new fixtures such as the toilet, sink, and shower can be installed. Installing tiles and other finishes usually takes an additional few days.

Medium-Sized Bathroom (3-4 weeks)

Plumbing and Electrical Work (4-5 days): A slightly larger bathroom or a more complex renovation will add a few days to the plumbing and electrical work.

Installing Fixtures and Finishes (7-10 days): Larger spaces and more intricate designs mean that installing new fixtures, tiles, and finishes will take longer.

Large Bathroom (5-6 weeks)

Plumbing and Electrical Work (6-7 days): A large bathroom or major layout changes can extend this step.

Installing Fixtures and Finishes (10-14 days): Finishing a larger bathroom with custom fixtures and detailed tile work can add more time.

While these time frames provide a general idea, it's important to consider that unforeseen circumstances or project complexity could influence the final timeline.

Demolition (2-5 days)

Smaller bathrooms: Demolition can be completed within 2-3 days for a straightforward bathroom with standard materials.

Larger or more complex bathrooms: This may take up to 4-5 days, particularly if dealing with tougher materials like brick or structural changes.

Rough Plumbing and Electrical Work (1-4 days)

Smaller bathrooms: Basic plumbing and electrical work, especially if no fixtures are being relocated, can be completed in 1-2 days.

Larger bathrooms or complex changes: When fixtures are being moved or upgraded, this step can take up to 3-4 days.

Preparation for Tiling (1-3 days)

This stage involves ensuring the walls and floors are even and ready for tiles. The drying process for materials like cement slabs will take some time.

Smaller projects: 1-2 days.

Larger projects: Up to 3 days, especially for larger or more intricate tiling plans.

Tiling and Waterproofing (5-10 days)

Smaller bathrooms: Tiling and waterproofing usually take 5-7 days, as waterproofing requires several coats with drying time in between.

Larger bathrooms: This can extend up to 8-10 days, especially if large tiles or custom tile arrangements are involved.

Installing Fixtures and Fittings (3-7 days)

Smaller bathrooms: Installing the sink, toilet, shower, or bath can take around 3-4 days.

Larger bathrooms: Complex setups or multiple fixtures can take up to 5-7 days, particularly for custom cabinetry or intricate finishes.

Final Touches (1-2 days)

This includes adding accessories such as mirrors, towel rails, and final paint touch-ups.

Smaller bathrooms: 1 day.

Larger bathrooms: May take up to 2 days if more fixtures and accessories are involved.

 

Why Can a Bathroom Renovation Take Longer than Expected?

It is very rare to complete a bathroom renovation project on the exact deadline that you first initially hoped and scheduled for. It is likely that there may be some delays, so here are some things that may cause a delay during your bathroom renovation:

Unforeseen Issues

During the removal phase, hidden problems such as plumbing or electrical issues, water damage, or structural deficiencies may be discovered. Addressing these problems can extend the timeline.

Permits and Inspections

You’ll need to get your electrical work signed off but this is done by your electrician. If you’re planning a large-scale renovation and altering drainage, or adding a bathroom to a loft conversion or an extension for example, you may need planning permission. But in the vast majority of cases, this won’t be necessary.

Contractor Availability

Delays can occur if the contractors or subcontractors are unavailable due to scheduling conflicts, unexpected absences, or high demand in the construction industry.

Tip: Instead of hiring tradesmen separately, a good plumber will organise other trades, for you, if and when required. This is more efficient, cheaper and it is also hassle-free since you don’t have to do the juggling and scheduling of tradesmen yourself. Their quote normally includes all work, e.g. tiling, electrical etc.

Availability of Materials

With the current supply chain shortage, it is much more difficult to ensure that your materials will be delivered on time. Be aware that imported tiles and fixtures will also take longer to arrive too.

Tip: You could be extra vigilant and place your order a couple of months before so you know for sure they will arrive before your project starts.

Customisation

If your project involves custom-made materials, fixtures, or cabinetry, the production and delivery of these items may experience delays. Again, make sure to get a head start on all of these details, to minimise delays.

Ways That You Can Minimise Delays in Your Bathroom Renovation

Now that you know there could potentially be delays, here are some ways that you can prevent them from happening:

Thorough Planning

Start with a well-thought-out plan that includes a detailed scope of work, material selections, and a realistic timeline. Make sure to involve a professional designer or contractor to assist in the planning process.

Stick to The Plan 

Once you have solidified your plan, stick to it. Deviating from the plan can incur extra time and cost.

Clear Communication

Maintain open and transparent communication with your contractors and subcontractors. Regularly discuss the project's progress, any concerns, and expectations.

Quality Contractors

Hiring reputable, experienced contractors can help reduce delays caused by mistakes or mismanagement. Make sure to check references and reviews before making your selections.

Temporary Accommodations:

If the bathroom is your only one, plan for temporary solutions, like a portable toilet or using a neighbour's bathroom during the renovation.

Conclusion

The duration of a bathroom renovation project largely depends on its size and complexity. Careful planning, efficient scheduling, and working with experienced professionals can help streamline the process.
