A beautiful bathroom can bring us a lot of joy. Unfortunately, bathroom renovations can often be expensive, which is why many of us attempt to DIY our bathrooms. Although Bunnings and IKEA aim to make this seem easy, in reality, it’s easy to make mistakes, often leading to a faulty renovation that will need to be fixed up by experts. In this article, we explore some of these common mistakes.

Common DIY Bathroom Renovation Errors

Cost Blowouts

Building a bathroom is a costly job, and it becomes even costlier when people DIY their bathroom renovation. Even if they begin with a budget, there may be small costs which occur during the renovation – and these small costs quickly add up. Even a minor makeover can quickly morph into a money pit.
Avoid overspending – create a budget and stick to it. The best way to do so is through consulting professionals, because they may be able to pick up something about your bathroom that you may not be aware of.

DIY Waterproofing

Waterproofing seems easy enough, but there’s a reason professionals get trained in it. Many people make the mistake of trying to waterproof their own bathroom, which eventually results in a leaky shower.


We have an idea for what our ideal bathroom would look like, but it can be difficult to visualise. For many DIYers, this leads to an overcrowded bathroom. This could have easily been avoided with the 3D design that we offer, which ensures your bathroom would have sufficient space for all your needs.

Inappropriate Materials

All surfaces in a bathroom must be sealed and waterproof, otherwise they will rot, swell or discolour with time.
This also extends to aesthetics: what may be in style at the moment may not necessarily be a smart choice for your bathroom. Instead, we recommend going for a timeless, elegant finish, designed to match the rest of your home.

Poor Drainage

Although it may seem simple, poor drainage is a common mistake – which leads to a wet and slippery floor, and eventually mould. Every wet area requires fall, which is a slope allowing for drainage. Ensure that this will be included in your bathroom.
