Before you add those stylish tiles or give your bathroom walls a fresh coat of paint, there’s a crucial step you shouldn’t overlook: waterproofing. 

But what does it actually cost? Let’s delve into the world of bathroom waterproofing and unravel the factors that influence its cost in Singapore.

Understanding Bathroom Waterproofing

Bathroom waterproofing is not just about aesthetics; it’s about safeguarding your home from potential water damage and ensuring the longevity of your bathroom floor and bathroom walls. 

Essentially, it involves creating a protective barrier by using waterproofing products to prevent water leakage from seeping into the walls, floors, and other structures of your bathroom. 

Without proper waterproofing, water leaks can lead to a host of problems, including structural damage, peeling paint, mould issues, and even compromising the integrity of your home.

Therefore, investing in quality waterproofing and tiles is essential to protect your investment and maintain a functional and beautiful bathroom for many homeowners for years to come.

Benefits of Bathroom Waterproofing

Prevents Water Damage

One of the primary benefits of bathroom waterproofing is its ability to prevent water damage. By creating a protective barrier, waterproofing your bathroom ensures that water stays where it belongs – within the confines of shower walls and your bathroom fixtures. 

This helps to avoid costly repairs caused by water seepage into walls, floors, and ceilings, which can weaken structures and lead to mould growth.

Maintains Structural Integrity

Waterproofing not only protects against water damage but also helps maintain the structural integrity of your home.

By preventing moisture from infiltrating building materials, waterproofing extends the lifespan of your bathroom and reduces the risk of structural issues such as rotting wood or crumbling concrete.

Enhances Hygiene

A waterproof bathroom is easier to clean and maintain, leading to better hygiene. Waterproof surfaces resist moisture, preventing the growth of mould and mildew that thrive in damp environments. 

This not only keeps your bathroom looking fresh and clean but also contributes to building a healthier living environment for you and your family.

Preserves Aesthetic Appeal

Waterproofing your toilet and shower allows you to prevent moisture and preserve the aesthetic appeal of your bathroom for longer. 

By preventing water damage, it helps to maintain the appearance of tiles, paint, and other finishes, ensuring that your bathroom remains visually appealing for years to come without the need for frequent repairs or renovations.

Increases Property Value

A waterproof bathroom adds value to your home. Potential buyers are more likely to be attracted to a property with a well-maintained bathroom that is protected against water damage. 

By investing in a waterproofing system now, you not only protect your home but also potentially increase its resale value in the future.

What Factors Affect the Cost of Waterproofing Your Bathroom?

Size of the Bathroom

Larger bathrooms typically incur higher waterproofing costs due to the increased amount of materials and labour needed to cover the larger surface area effectively.

For an average-sized bathroom in Singapore, which is around 4 to 6 square meters, waterproofing costs may range from SGD 800 to SGD 1,500.

Extent of Waterproofing Needed

The extent of waterproofing required per shower area also influences costs. If your bathroom has multiple fixtures, such as showers, bathtubs, and sinks, each shower area will need to be waterproofed separately, increasing the overall cost.

Quality of Waterproofing Material

The quality of waterproofing materials used can vary widely with poor application, from basic sealants to premium membranes.

Higher-quality bathroom waterproofing materials generally come with a higher price tag but offer better durability and protection against water damage in the long run.

Type of Waterproofing Method

Various methods of waterproofing bathrooms exist, including membrane systems, liquid waterproofing, and cementitious coatings. The method chosen can impact costs, with some waterproofing methods requiring more labour and materials than others.


The accessibility of your bathroom can also affect the costs of waterproofing. If your bathroom is located on an upper floor or in a hard-to-reach or wet area somewhere, it may require additional labour and equipment for waterproofing, resulting in higher costs.

The Extent of Repairs Needed

Suppose your bathroom has existing water damage or structural issues that need to be addressed before waterproofing work can take place. In that case, the cost of repairs will add to the overall waterproofing cost and expenses.

Local Labour and Material Costs

Labour and material costs can vary depending on several factors and on location. In Singapore, where labour and material costs are expected to be relatively high, waterproofing costs will be on the higher side compared to other regions.

Quality Service Matters

While it might be tempting to opt for the lowest price, remember that quality service is key. Faulty waterproofing can lead to water damage, leaks and structural issues down the line, costing you more in repairs.
