Ensuring that a wet area abides to the BSI tanking regulations is not only a revision, it also ensures that the installation is of quality and water-tight.
Tiling, grouting and silicone surfaces can absorb so much water that the underlying substrate can get damaged. This could be from leaks or mould if the cubicle isn’t completely water-resistant, and replacing all three can be a costly and laborious task.
The revision ensures that standards are improved for homeowners. This also stamps out any possibility of long-term effects further down the line once the shower has been installed. Although the revision does come with a larger price tag due to more materials, labour cost and longer installation times.
If regulations are not met during development on a new build, you will be liable for any repairs required. This can cost thousands as you will still be accountable to pay if the damage has spread to any other rooms from damp and shower leaks.
