I would not recommend any one else for your plumbing and bathroom renovations, from the first engagement over phone, to hand over at the end. Communication throughout was excellent and completed the job in a timely manner. Thanks Rick and the team at Nutrend. 10/10

Nu-Trend was contracted to complete a renovation of two bathrooms in this old house in Penshurst. The main bathroom had an old corner spa bath they wanted to be removed & the second small bathroom had a doorway leading to the outside they wanted removing. 

The owner wanted to spend their renovation budget on high-quality workmanship vs expensive bathroom fixtures so their product choices were conservative, but still meant we could complete a high quality finish for both rooms.

Our work started by completely demolishing both bathrooms and as we normally do, we always make sure the bathroom plumbing as well as the structure of the rooms are sound before we being our renovating work.

Unfortunately for this house we discovered the floor was suffering from concrete cancer which we needed to repair. So apart from blocking off an old door the rest of the job was fairly normal with end to end project management, drop sheeting, cleaning, tiling, water proofing, demolition, rubbish removal, rendering, electrical, carpentry and painting.

The total time frame to complete this renovation job was about six weeks with the slight delay from the concrete cancer repairs. Thankfully the client was fast to process our reports & accept the variation costs involved.

All the products were purchased from BBC Tiles with the total budget between $50,000 and $60,000 for the whole job.

How to repair concrete cancer in your bathroom

We had to repair the concrete cancer in this bathroom that was being caused by failed waterproofing in the shower area of the bathroom.

Concrete cancer can be a serious and expensive issue if left untreated, misdiagnosed or just given a quick repair. Concrete cancer is caused when steel re-enforcing within a concrete slab begins to rust. As the steel rusts, it expands and displaces the surrounding concrete causing it to become brittle and crack.

Signs of concrete cancer can include; delaminated & cracking concrete called spalling, rust stains which seem to leak out from within the concrete, bubbling or plating of concrete render or leaks which appear over concrete surfaces.

For this bathroom it was important to have repairs made to the floor to ensure there wouldn’t be issues later. We discovered that the water proofing in the shower had failed so water was getting into the subfloor. Fortunately it was limited to just one corner of the room and the rest of the slab wasn’t damaged.

While we were under the house we checked the other timbers and the rest of the slab which looked great. So it meant we could wet saw cut a larger section out to remove the crumbled pieces, install new steel bars and repair the area ready to be renovated on.

It’s a good thing we detected this issue now before it spread into a larger area of the slab. Concrete cancer can be a serious and expensive issue if left untreated especially when it is under wet areas like a laundry, kitchen or bathroom.

Can a door be removed to make a bathroom bigger?

A lot of homes in Sydney have a laundry that was converted to a bathroom where the old sink was removed and maybe a toilet, shower and vanity was installed. Typically these rooms will also have a door to exit the building to the backyard.

So many home owners these days are converting their laundry into a bathroom to make more usable space in the house. 

So part of the renovation for this small bathroom was to brick up the old door to make more usable space in the bathroom. It meant the layout could be changed so that the vanity was against the wall to then make more space for the walk in shower.

The window was retained to give the room some natural light, but this is a great way to create more space without knocking down walls.

For this house it was easy to make both bathrooms feel larger than they did before. By removing the big, bulky corner spa bath that wasn’t being used it made the whole corner of the room available. Blocking up the exit door in the other bathroom created a whole new wall surface to work with. So the existing bathroom plumbing could be used but new shower, toilet, vanity & tiling could be installed. The interior design choices were relatively simple which is a great way to save money & ensure the rooms can appeal to a wide range of people.

The floor tiles are perhaps the most interesting aspect with their timber look textured design.
