Our band, before extras
Our price band · supplied and laid
Set Sep 2026.
Supplied and laid, with standard installation. Major levelling or screeding, removing and disposing of the old floor, new skirting, special transition profiles, door trimming and other remedial work are normally extra, priced after a site inspection. Some products cost more. GST is added or included as the final quotation states.
The sky goes dark
October's thunderstorms come in the afternoon and early evening, the Meteorological Service says, at times severe. In a storm, water reaches a floor four ways: on shoes at the door, off the sink, in the bathroom, and through a window someone left open.
Four ways in. Let's walk them, shoes off.
“In a storm, water reaches a floor four ways: on shoes at the door, off the sink, in the bathroom, and through a window someone left open.”
The door
Wet shoes bring in water and grit. On its vinyl, Karndean's care guide asks for mats with non-rubber backing at doorways, and for loose grit to be cleaned up, since it can cause fine scratches.
On vinyl, a mat at each door to outside. Non-rubber backing.
The kitchen

3D render
In HDB's Kim Keat Crest brochure (Feb 2026), 3-room and bigger flats' kitchens and bathrooms come with glazed porcelain floor tiles; check your own project's brochure. Vinyl by the sink is a different story. Some makers call their vinyl waterproof; a flooring firm's director told Home & Decor the material resists water, but water can still seep in at the joints, if the locking system lets it, and get trapped underneath.
Tiles by the sink stay. Put the money in the living room.
The bathroom

3D render
The bathroom is where water belongs, so we'd keep it tiled. In an HDB flat, a replaced bathroom floor goes down over pre-packed waterproofing screed and a waterproofing membrane, which HDB says is what keeps water from leaking into the ceiling of the flat below. And a new block's toilet floor and wall finishes can't be replaced for 3 years from its completion.
Warm grey textured tile, and a light by the door for 3am.
The window

3D render
Karndean says topical spills cleaned up promptly won't harm its rigid core floor, properly laid and in normal use. Rain left sitting is different: a flooring firm's director told Home & Decor problems can develop over time, and Karndean calls standing water on its floor a slip hazard.
Close the window. Then the towel.
The edges
Water gets in where a floor stops. Karndean's installation guide says that in potential wet areas, a flexible sealant may be used to protect the expansion gap at the walls and fixed furniture from water.
Ask which edges near water get a flexible sealant, in writing.
What the quote must say
Which rooms stay tiled.
Where the vinyl stops, and the strip that finishes it. Our price band normally leaves special transition profiles out.
Which edges near water get a flexible sealant.
Three lines. If one is missing, ask before you sign.

- "The vinyl material itself is water-resistant and won't absorb moisture like natural wood. However, water can still seep through the gaps or joints if the locking system allows it, and over time, it gets trapped beneath the flooring."
- "If water is just left sitting there, or if it repeatedly seeps beneath the surface, underlying issues can still develop over time."

- "Pre-packed waterproofing screed and waterproofing membrane must be used in bathrooms/ toilets before laying new floor finishes."
- "A waterproofing membrane is laid on the cement screed before laying floor finishes in toilets. This prevents water from leaking through the floors into the ceiling of the flat immediately below."

Karndean, 2G Rigid Core installation guidelines (Australia and New Zealand) · Aug 2023
- "When installed properly and under normal use, damp mopping and topical spills cleaned up promptly will not harm the performance of the floor."
- "Do not subject this product to standing water. This will present a slip hazard."
- "In potential wet areas where it is necessary to protect the expansion gap between perimeter walls, fixed furniture and the flooring product from potential water exposure, a flexible acrylic or flexible low modulus neutral cure silicone sealant may be used. Sealant should not be used for the general filling of expansion gaps."
- In potential wet areas, "a flexible acrylic or flexible low modulus neutral cure silicone sealant may be used" to protect the expansion gap from water.
