Bathroom Renovations for Asquith's Bush-Edge Homes

Asquith sits right against the bush. It is a lovely place to live and a hard place for a bathroom to stay dry.

The houses

Asquith runs along the railway line north of Hornsby, with bushland reaching into the backs of many of its streets. Its housing is mostly modest, older homes: post-war fibro and weatherboard cottages, brick houses from the fifties and sixties, and some later townhouses and villas.

Many have been extended at the back over the years, often with a sleepout, a family room or a second bathroom tacked onto the original plan. The joins between old and new are frequently where problems sit.

Living next to the bush

Asquith's biggest renovation influence is its setting.

Shade and damp. Houses that back onto bushland, or sit under large trees, may get very little direct sun on the bathroom side. Walls and ceilings stay cool, and warm shower steam condenses on them. Mould on the ceiling, black spots on grout and peeling paint are common.

Subfloor moisture. On sloping blocks near the bush, groundwater and runoff can keep the subfloor damp. That affects the timber under the bathroom and is worth checking while the floor is open.

Leaf litter and gutters. Blocked gutters over a bathroom can send water into walls and around windows. It is not a bathroom problem as such, but it is often behind a damp patch blamed on the shower.

Bushfire-prone land. Large parts of the area are mapped as bushfire-prone. Internal work is usually unaffected, but a new or enlarged window in a job that needs approval may need to meet bushfire construction requirements.

What an Asquith bathroom renovation focuses on

Ventilation first

A correctly sized exhaust fan, ducted outside rather than into the roof space, with a run-on timer so it keeps clearing the room after the shower stops. Where the duct runs through a cold roof, insulating it stops condensation forming inside and dripping back.

Finishes that handle moisture

  • Wet-area ceiling lining and mould-resistant paint
  • Tile to the ceiling in the shower so there is no painted surface near the spray
  • Epoxy or high-performance grout on the shower floor
  • Moisture-resistant vanity with sealed edges
  • Heated towel rail or heat lamp to help the room dry

Dealing with old construction

Many Asquith bathrooms have fibro wall or ceiling linings. An asbestos test comes first, and if positive, a licensed removalist takes it out before the renovation continues.

Mortar-bed floors without a membrane are typical, and so are softened floor timbers underneath. The quote should include a repair allowance so a rotten joist does not become a dispute.

Cottages and small rooms

Fibro and weatherboard cottages often have a narrow bathroom at the back of the house, sometimes with the laundry beside it. Combining or reorganising those two rooms can give a better bathroom and a more practical laundry at the same time. See laundry renovations and small bathrooms.

Townhouses and villas

Asquith also has a number of townhouse and villa developments. These are often strata or community title, so owners corporation approval is usually needed where the waterproofing is being replaced. Their bathrooms are generally on slabs, with fixed waste positions.

FAQs

Questions people ask before they commit

Why do Asquith bathrooms get so mouldy?

Many homes back onto bushland, sit under a canopy and face away from the sun. Bathrooms on that side stay cool and damp, and without a ducted exhaust fan, steam condenses on the ceiling and walls. Better ventilation and suitable finishes make the biggest difference.

Does bushfire-prone land affect my bathroom renovation?

Internal work is generally unaffected. If you are replacing or enlarging a bathroom window as part of work that needs approval, the bushfire construction standard for your site may apply to the new window. A certifier can confirm.

Are Asquith houses likely to contain asbestos?

Many were built or extended when fibro was common, including in bathrooms, laundries and enclosed verandahs. Any sheeting in an older house should be tested before it is disturbed.
