Factors that affect the cost of waterproofing services

There are jobs that you can do by yourself, but bathroom waterproofing is definitely not one of them. Bathroom waterproofing is best left to qualified experts, and in order to prepare for the cost of hiring professionals, you need to understand the factors that can affect the final price of the job.


Since plenty of waterproofing businesses quote on a per-square metre basis, the size of your bathroom will naturally affect the actual cost of the project. The price also depends on whether you want the entire bathroom waterproofed or just a particular area like the shower floor.


Liquid-applied membranes are the most widely used material for wet areas like bathrooms. Different types of membrane include acrylic, chlorinated rubber or latex, epoxy, polyurethane, polyester resin, and tar epoxy. When it comes to bathroom waterproofing, there is no clear best option, as it will all depend on the application and other job-specific requirements. Additionally, membranes vary in elasticity, and those with higher elasticity typically offer more protection.

Labour costs

Hiring a licensed waterproofing business may seem costly at first, but it’s definitely a worthy investment. Also, remember that the cheapest quote does not necessarily mean it’s the best one for your budget. By hiring unlicensed or shady tradesmen, your bathroom becomes at risk of being damaged. This is will definitely cost you more in the long run.
