“How much will it cost?” is usually the first question we get asked about a bathroom renovation, and it’s also the hardest to answer with a single number — because the honest answer is: it depends on the room, the finish level, and what’s behind the walls once we get started. This guide walks through what actually drives a bathroom renovation quote in Hobart, why we don’t publish a fixed price list, and how to budget sensibly without cutting corners on the parts of the job that protect your home.

What actually drives the cost
A bathroom renovation quote is built from a handful of real cost drivers, not a flat rate per square metre:
- Layout changes — keeping the existing layout is almost always cheaper than moving plumbing for a new toilet, shower or vanity position. Relocating drainage means opening up the slab or subfloor, which adds both cost and time.
- Waterproofing and structural condition — older homes sometimes have subfloor or wall damage that isn’t visible until demolition starts, particularly around old shower bases that have been leaking slowly for years.
- Fixtures and finishes — tiles, tapware, vanities and shower screens all range hugely in price, and this is usually where a budget moves the most.
- Size and complexity — a small ensuite is a smaller job than a full family bathroom with a separate bath and shower.
- Compliance work — waterproofing, plumbing and electrical work has to meet Australian Standards and be certified, regardless of how the room looks. This isn’t optional, and it shouldn’t be quoted as if it were.
Why we don’t publish a fixed price list
Plenty of renovation websites list a “from” price for a bathroom renovation. We’d rather not, because a number like that tends to set an expectation that doesn’t hold up once we actually see the room. Two bathrooms that look similar on the surface can price very differently once you factor in plumbing runs, wall condition, and the finish level you’re after.
What we do instead is visit the property, understand what you actually want from the space, and put together a detailed, itemised, fixed-price quote — so you know exactly what you’re paying for before any work starts.
Labour vs materials: where your money goes
On a typical bathroom renovation, a substantial share of the budget goes to labour and trade coordination — demolition, waterproofing, tiling, plumbing and electrical fit-off — rather than the visible fixtures alone. This is one reason two bathrooms with near-identical tiles and tapware can still land at different prices: the labour required to waterproof, level and correctly fall a floor to the drain doesn’t change just because the finishes look similar.
Worth knowing: waterproofing that isn’t installed and tested to AS 3740, the Australian Standard for waterproofing wet areas, is the single most common cause of expensive bathroom repairs down the track — usually well after the renovation is finished and forgotten about.
Older Hobart homes and hidden costs
Hobart’s housing stock is a mixed bag — sandstone cottages in Battery Point, weatherboard character homes climbing the slopes of West Hobart, brick-veneer family homes across the northern suburbs, and newer builds on the Eastern Shore and around Kingston. A bathroom renovation in a 1920s cottage is a different job to one in a 2015 build, and we plan every project around the house we’re actually working in, not a one-size-fits-all package. Older subfloors, outdated plumbing materials, and previous unpermitted work are all things that can genuinely only be assessed once demolition starts — which is why a sensible contingency, not a false sense of certainty, is part of an honest quote.
Managing your budget without cutting corners
- Keep your existing layout where it genuinely works, and spend the savings on fixtures and finishes instead.
- Don’t compromise on waterproofing or compliance — it’s the one part of a bathroom renovation you really don’t want to shortcut.
- Be upfront with your renovator about your budget range early, so the quote reflects what’s realistic rather than a wish list.
The most expensive bathroom renovation is the one that has to be redone in five years because the waterproofing wasn’t done properly the first time.
Getting an accurate quote
The only way to get a genuinely accurate figure is a proper site visit — photos and phone descriptions can’t show us what’s behind the tiles.
