Bathrooms and toilets are regularly exposed to water, moisture, and humidity. If water gets into areas where it should not, it can affect walls, floors, ceilings, and nearby rooms.
Toilet and bathroom waterproofing in Singapore helps provide a suitable water-resistant barrier in areas that are regularly exposed to water. Proper waterproofing is especially important during bathroom renovation, repair, or new installation work.
One Hub Integrated Pte Ltd provides toilet and bathroom waterproofing services in Singapore based on the property’s condition and project requirements. We can assist with waterproofing work as part of a bathroom renovation or as a separate project where suitable.
Started in 2021, One Hub Integrated has served 150+ clients across Singapore.
Bathroom waterproofing requirements vary depending on the existing construction, surface condition, and project scope.
Our services may include:

Bathrooms are among the wettest areas of a property.
Water can come from:
Without suitable waterproofing, unwanted moisture can potentially reach surrounding building materials.
Possible signs of a moisture-related problem include:
Waterproofing is therefore an important consideration when constructing, renovating, or repairing wet areas.
Waterproofing is commonly considered as part of a bathroom renovation project.
A bathroom renovation may involve:
The exact sequence depends on the project and existing bathroom condition. For a complete bathroom renovation, see our Bathroom Renovation Singapore page.
Tiles provide a finished surface, but the tile layer itself should not be treated as the complete waterproofing system.
Where waterproofing is required beneath tiled wet areas, the underlying surface should be properly prepared before the waterproofing system is installed.
Once the required waterproofing work has been completed and is ready for the next stage, tiling can proceed according to the project plan.
For tiling requirements, visit Tiling Services Singapore. You can also explore Bathroom Tiling Singapore.
Bathroom floors are exposed to frequent water and moisture.
Floor waterproofing may be considered around areas such as:
The exact waterproofing coverage depends on the bathroom layout and construction requirements. A properly prepared surface is important before waterproofing work begins.
Some bathroom walls are exposed to regular water, particularly around shower areas.
Depending on the project, waterproofing may be required on selected wall sections as well as the floor.
The exact areas should be determined according to the bathroom design, water exposure, existing construction, and project requirements.
HDB bathroom projects can involve additional planning because the property is part of a managed residential environment.
If you are renovating an HDB bathroom, applicable HDB requirements and any relevant rules should be checked before work begins.
Our HDB Renovation Singapore page provides more information about HDB renovation work. For HDB painting requirements, visit HDB Painting Singapore.
Condominium bathrooms may also require waterproofing during renovation or repair.
However, condominium developments can have their own management requirements, access arrangements, working hours, and renovation procedures.
Before starting work, applicable management or MCST requirements should be confirmed.
For broader condominium renovation, see Condo Renovation Singapore. For condo painting requirements, visit Condo Painting Singapore.
Water leakage and waterproofing are related but different services.
Waterproofing is intended to provide protection against water penetration in suitable areas. Water leakage repair focuses on identifying and addressing an existing leakage problem.
If your bathroom already has visible leakage, dampness, or recurring water stains, the cause should be investigated before simply applying a new waterproofing layer.
For leakage-related concerns, see our Water Leakage Inspection Singapore service. For confirmed leakage problems, visit Water Leakage Repair Singapore.
A waterproofing or moisture problem may show itself through different symptoms.
Common signs include:
These symptoms do not automatically prove that waterproofing is the cause. Plumbing, drainage, sealant, or other building issues can produce similar signs. Proper inspection is important before deciding on the required repair.
If an existing bathroom is being renovated, the condition of the underlying surfaces should be considered before new finishes are installed.
Depending on the renovation scope, existing tiles and other finishes may need to be removed before the underlying surface can be assessed.
Our Bathroom Hacking Singapore service may be relevant when existing bathroom finishes need to be removed as part of the renovation.
After the necessary preparation and waterproofing work, new bathroom finishes can be installed according to the renovation plan.
Plumbing problems can sometimes cause water leakage in bathrooms.
Examples may include issues involving:
Waterproofing should not be used as a replacement for repairing a defective pipe or plumbing connection.
For plumbing requirements, see Plumbing Services Singapore. For pipe-related work, visit Pipe Repair & Replacement Singapore. For water heater-related plumbing, see Water Heater Plumbing Singapore.
Bathroom waterproofing and tiling are often connected during renovation.
A typical project may involve:
The exact process and materials depend on the project. For bathroom tile installation, see Bathroom Tiling Singapore.
Old or damaged grout can allow water to reach areas where it is not intended to go, but replacing grout is not always the same as fixing a waterproofing failure.
If the issue appears to be limited to deteriorated grout, regrouting may be considered.
For this service, visit Tile Regrouting Singapore.
If there is persistent water leakage or dampness, further investigation may be necessary.
The exact process depends on the bathroom and project scope, but a waterproofing project may involve several stages.
The bathroom's condition and the reason for waterproofing are discussed.
The relevant floor, walls, wet zones, and visible moisture concerns are reviewed.
The surface is cleaned and prepared according to the waterproofing requirements.
The selected waterproofing system is applied to the agreed areas.
The waterproofing system should be allowed to set or cure as required before subsequent work.
Once ready, the next renovation stage, such as tiling, can proceed according to the project plan.
The timeframe depends on the bathroom size, existing surface condition, preparation work, waterproofing system, drying or curing requirements, and other renovation activities.
If hacking, plumbing, tiling, or other work is also required, the overall project duration may be longer. A specific timeframe should therefore be based on the actual bathroom and scope.
Bathroom waterproofing costs vary depending on factors such as:
For this reason, a quotation should be based on the actual project requirements rather than a single fixed price.
Waterproofing requirements depend on the bathroom’s construction, renovation scope, and applicable project requirements.
If an existing bathroom is being renovated, the condition of the underlying wet-area surfaces should be considered before new finishes are installed. Where waterproofing is required, it should be planned as part of the renovation rather than treated as an afterthought.
