Bathroom renovation reviews near Kanwal

"Our ensuite was original 1980s and we wanted to reconfigure the layout completely. Got quotes through Alljack for the full scope, demolition through to tiling. The plumber we chose was honest about what was possible with our slab and didn't oversell the job. Really happy with the result."

Signs Your Kanwal Bathroom Needs a Full Renovation

Failed waterproofing — mould, damp, or peeling tiles

The most urgent sign. Mould behind tiles, soft walls, or damp patches on adjacent walls indicate the original waterproofing membrane has failed. In Kanwal's 1970s–80s bathrooms, the waterproofing is either non-existent (pre-code) or has reached end of life. Water ingress damages the structural framing and must be fixed.

Original 1970s–80s coloured suite still in place

Avocado green, harvest gold, and chocolate brown bathroom suites are a sure sign the bathroom is original. Beyond aesthetics, these fixtures are 40–50 years old — the drain rough-in, supply connections, and cistern mechanisms behind them will be in the same condition.

Slow shower drain that repeatedly blocks

A shower drain that blocks every few weeks despite clearing usually means the drain line is undersized, incorrectly graded, or has a partial root intrusion. In older Kanwal homes, the original 40mm shower waste is smaller than current code — renovation is the opportunity to upgrade it.

Poor hot water pressure in the shower

Weak hot water pressure in the shower while cold pressure is fine points to a corroded hot water supply line feeding the bathroom — common in Kanwal's older galvanised pipe homes. Renovation is the right time to replace the supply lines to the bathroom, not just the tapware.

Cramped layout not suited to current lifestyle

1970s bathroom layouts often have the toilet in the full view of the doorway, small shower recesses, and no separate vanity area. Relocating fixtures during renovation — moving the shower waste, repositioning the basin outlet — is plumbing work that requires a licensed plumber.

Bathroom Renovation Plumbing in Kanwal — What's Involved

What to expect in Kanwal's 1970s–80s homes

Kanwal's housing was built almost entirely in a 15-year window in the 1970s and early 1980s. These brick veneer homes typically have bathrooms with a small shower recess, separate bath, wall-mounted basin, and a separate toilet. The waterproofing ranges from inadequate to non-existent by current standards, and the drainage and supply rough-in was done to codes that are now significantly out of date.

Waterproofing often absent or failed in pre-1990 bathrooms Critical
Drain rough-in 40mm wastes common — now minimum 50mm Replace
Supply lines galvanised or early copper needing replacement Replace
Asbestos check pre-1987 homes — assess before demolition Essential

The plumbing stages of a bathroom reno

Bathroom plumbing renovation is done in two stages around the tiler and waterproofer:

Stage 1: Rough-in new drain, waste, and supply lines positioned Before waterproof & tile
Waterproofing inspection plumber checks drainage falls before membrane Critical step
Stage 2: Fitoffs shower rose, tapware, vanity, toilet installed After tiling
Compliance certificate issued by licensed plumber, required by law Mandatory

All plumbing work must comply with AS/NZS 3500. Waterproofing must comply with AS 3740 and is inspected before tiling begins.

Plumbing costs in Kanwal bathroom renos

Full rough-in (drain, supply, waste relocation) $2,500–$5,000 1–2 days
Fitoffs (shower, basin, toilet, tapware) $1,500–$3,000 1 day
Like-for-like fitoff (no relocation) $800–$1,800 Half day
Supply line replacement (galvanised to copper/PEX) $600–$1,500 Add-on

Plumbing is typically 15–25% of a total bathroom renovation budget. Getting 3 quotes for the plumbing component via Alljack before committing to the full project gives you an accurate picture of total costs.

Kanwal-specific renovation considerations

Most Kanwal homes are single-storey brick veneer with concrete slab floors. This means drain rough-in changes require core-drilling through the slab — a standard part of bathroom renovations, but one that adds cost if new drain positions are required. The slab construction also means no subfloor access, so waterproofing the shower recess properly is critical to prevent water migration through the slab into the soil beneath.

Concrete slab homes Core drilling required for drain relocation
Pre-1987 builds Asbestos check before any demolition
Original single-bathroom layouts Fixture relocation common in renos
Outdoor access Larger Kanwal lots allow easier inspection access

Bathroom Renovation Kanwal FAQs

How much does bathroom renovation plumbing cost in Kanwal?

Plumbing for a bathroom renovation in Kanwal typically costs $2,500–$5,000 for a full rough-in (relocating or replacing drain, supply, and waste lines) and $1,500–$3,000 for fitoffs (installing the new shower, basin, toilet, and tapware once tiling is complete). In Kanwal's 1970s–80s homes, the old drainage and supply rough-in often needs to be completely replaced rather than reused — this ensures the renovation complies with current Australian Standards. With Alljack you get 3 competitive quotes to compare before committing.

Do I need to replace all the plumbing during a bathroom reno in Kanwal?

In most of Kanwal's 1970s–80s brick veneer homes, yes — the existing drainage rough-in and water supply lines are likely at or past end of life. Old clay or early PVC drain lines in the slab may be cracked or have deteriorated joins. Galvanised supply lines are often corroded. A plumber will assess whether the existing rough-in can be reused. Cutting corners risks waterproofing failures and expensive rectification after tiling.

Can a plumber quote for just the plumbing part of my Kanwal bathroom reno?

Yes — and it's the right approach. Plumbing quotes are split into rough-in (before tiling) and fitoffs (after tiling). Getting a plumber to quote the rough-in first gives you actual costs before committing to the full renovation budget. Alljack can get you 3 quotes specifically for the plumbing component — just describe the scope and we'll match you with qualified local plumbers.

Do I need to worry about asbestos in my Kanwal bathroom renovation?

Yes — this is an important consideration for Kanwal homes built before 1987. Asbestos-containing materials were commonly used in bathroom wall sheeting (fibro), floor tiles, vinyl tile adhesive, and around pipe penetrations in homes of this era. Before any demolition or drilling, have a licensed asbestos assessor inspect the bathroom. Your plumber is not permitted to disturb asbestos — this needs to be addressed before the renovation begins.
