Bathroom Renovation
Waterproof, elegant, and built to last.

Professional Bathroom Renovation
A bathroom renovation is one of the highest-value upgrades you can make to a home, but it is also the project where poor workmanship shows up fastest, usually as leaks, damp patches, and mould. That is why our bathroom renovation service is built around waterproofing done properly. We fully hack out the existing bathroom, prepare and level the substrate, and apply a proper membrane waterproofing system with correct falls to the floor trap, followed by a ponding test to confirm there are no leaks before tiling begins. Only then do we lay wall and floor tiles, install sanitary ware, vanities, shower screens, mixers, and accessories, and complete the plumbing, drainage, ventilation, and lighting. Good ventilation and the right materials are key to preventing the mould and musty smells common in Malaysian bathrooms, and we plan for both from the start. We regularly solve problems such as chronic leaks to the room or unit below, cracked and lifting tiles, poor drainage, cramped layouts, and dated fittings. Even a small bathroom can be transformed with clever layout, large-format tiles, wall-hung fittings, and good lighting to feel bright and spacious. As a CIDB-registered contractor serving Kuala Lumpur and Selangor, Tresman Builders delivers clean, elegant, leak-free bathrooms backed by a workmanship warranty and a transparent, itemised quote.

How It Works
Bathroom Renovation — Frequently Asked Questions
How do you prevent bathroom leaks and mould?+
We apply a proper membrane waterproofing system with correct floor falls and run a ponding test before tiling, and we plan ventilation and materials that resist mould in Malaysia’s humid climate.
What exactly is waterproofing and why does it matter?+
Waterproofing is a sealed membrane laid under the tiles that stops water reaching the concrete and the room below. Done correctly it is the single most important step in a lasting bathroom.
Can you renovate a small bathroom to feel more spacious?+
Yes. Large-format tiles, wall-hung toilets and vanities, glass shower screens, and good lighting make even a compact bathroom feel bright and open.
How long does a bathroom renovation take?+
A typical bathroom takes about 1–3 weeks including hacking, waterproofing, curing time, tiling, and fitting installation.
Do I need to hack the existing bathroom completely?+
For a lasting result we recommend full hacking so we can re-waterproof from scratch. Partial overlays risk trapping old leaks and failing sooner.
Can you supply the tiles, sanitary ware, and fittings?+
Yes. We can supply and install everything, or install items you have selected. We are happy to advise on durable, good-value choices.
Do you provide a warranty on waterproofing?+
Yes. Our bathroom work carries a workmanship warranty, and waterproofing products used are backed by manufacturer warranties.
