If I could give Nu-Trend 6 stars I would.

It’s a scary thing committing a large amount of money to a bathroom renovation but these guys make it as stress free as they possibly can.

Great communication from start to finish, professional, friendly, helpful advice and so easy to work with. They respected my property by providing covers on all the walkways and tidied up every day which was a bonus. Rick, Rob, Chris and all their associates obviously take great pride in their work and it shows.

I am very happy with my stunning new bathroom. Very highly recommended.

A new bathroom built with double vanity in Randwick, Sydney

We were contracted as a bathroom renovator in Randwick, Sydney to help the home owner solve a water leak issue in their old bathroom. You can read about the cause of the water leak here

At first glance the old bathroom looked ok, although what wasn’t obvious was the bathroom didn’t have the correct waterproofing or tiling applied when it was built. So over time gaps began appearing in the joins between the tiles which was letting water leak into the floors and walls. It got so bad the water leak was visible in the downstairs rooms.

Nu-Trend is bathroom renovation company in Sydney with a team of experienced renovation contractors and this includes plumbers; electrician, painter, tiler and carpenter that can manage the plumbing, electrical, tiling, painting and installation of new toilets, vanities and more.

For this home owner the first thing we had to do was identify the cause of the leak, our plumber didn’t take long once we inspected the tiling and realised the walls weren’t sheeted properly, there was incorrect waterproofing and the tiles didn’t have the right adhesives applied.

The scope of work
So the scope of work for this job included repairing the water damage, demolishing the old bathroom & then building a new one. 
Sydney bathroom renovation costs will vary a depending on the skills of the contractor and how much work is involved, for this project our scope of work included;

  • Water leak inspection
  • Bathroom demolition
  • Repairing the water damage
  • Preparing the walls and floors
  • New floor and wall sheeting
  • Waterproofing
  • New tiling installation
  • Finishing off with fixture and furniture installation, painting and lighting. 
The bathroom design brief
The existing layout for this bathroom was retained which included a free standing bath, vanity, toilet, walk in shower and two windows. The new design included a feature wall using 3D wall tiles which really set the room off and showed off the new bath tub really nicely.
Bathroom renovating steps 

The very general list of steps for renovating any bathroom in Sydney include the following;

1. Planning and Design: Helps in mapping out the vision for the bathroom, including the layout, materials, fixtures, and finishes. A well-thought-out plan ensures that the renovation meets your needs and stays within budget.

2. Budgeting: It’s crucial to have a budget in place to manage costs effectively and avoid overspending. A budget includes labour, materials, permits, and unexpected expenses.

3. Permissions and Approvals: Depending on the extent of the renovation, you may need approvals from the local council in NSW or comply with the development standards. This is to ensure safety and legality.

4. Using Professionals: Contractors, plumbers, and electricians may be needed to ensure the job is done professionally, safely, and to code. Their expertise is crucial for a successful renovation.

5. Demolition: The old bathroom fixtures, finishes, and structures need to be removed to make way for the new design. This step must be done safely to avoid damage to existing structures.

6. Plumbing and Electrical Work: These are foundational elements of the bathroom. Getting the plumbing and electrical right is essential for the functionality of fixtures like sinks, tubs, and lights.

7. Installation of New Features: This involves installing new fixtures, cabinetry, flooring, etc. Proper installation ensures the bathroom is functional, aesthetic, and durable.

8. Tiling and Painting: These finishings are essential for the aesthetic appeal and water resistance of the bathroom. Quality workmanship ensures longevity and adds value to the home.

9. Final Inspection: Ensures all works are completed to the planned design, quality standards, and building codes. It’s a critical step to address any issues before the finalisation of the project.

10. Clean Up: Post-renovation clean-up is essential to remove debris, dust, and leftover materials, making the space ready for use.te

Pretty shocking video footage isn’t it?

We have written a separate article about why this bathroom had a water leak here

Fortunately nobody in this home was hurt by tiles falling off the wall or the ceiling collapsing on the ground floor due to water damage, although it had the potential for this to happen.

This is an example of being very careful when you select a very cheap bathroom renovation quotation. There is a lot more detail and work that goes into renovating a bathroom and as this home owner has found out, they had to completely redo the bathroom again.

In some situations you might be able to stop the water leak if it is possible to repair just the area that is letting water escape. Although this normally doesn’t look very good as you can visually see a repair was done.



Take a look at our trusted 5 step process that we have refined after renovating thousands of bathrooms in Sydney. 

We document & detail every step so you know exactly what is happening during each stage of the renovation process.

Design ideas for a bathroom renovation in Randwick, Sydney

Double vanity in the bathroom 
One of the most practical things you can install in a new bathroom is a double vanity that has two sinks, two sets of storage drawers and matching mirror cabinet with storage.

This type of vanity is perfect for couples because two people can use the bathroom very easily while also having their own space for their toiletries and gadgets.

Timber vanity in a bathroom
Using timber in a bathroom can give it a feeling of warmth and luxury. Light colour timber can very easily blend into any interior design style to compliment the hard surfaces of the tiles on the floors or walls.

Drain waste
To save money on renovations of a shower some people will choose to install a simple drain waste that you can buy from Bunnings or Reece. 

These are fine of course, but if you want a touch of luxury then, a custom made floor waste can be integrated into the floor tiling so that it becomes almost ‘invisible’ when you look into the room. 

The wider opening can also capture more water too.

Wall hung vanity
If your vanity is wall hung it creates space on the floor that can help make a room feel larger and also cleaner. It is a visual illusion that adds a touch of luxury to any bathroom renovation.

This vanity was the first thing you see when you walk in the room so it immediately makes the bathroom feel larger than it is.

Tap placement
Every bathroom design needs to be checked and double checked. Our tradespeople will make sure that every item is spaced correctly and in the right locations before we complete the renovation work to install them.

Bathroom plumbing changes
Our team includes renovators and plumbers so this means we can adjust bathroom plumbing pipes either internally or externally. We can solve water leak problems, move connections and do other things that some renovators won’t be able to do.
