The cost to renovate an average size bathroom here in Australia is between $20,000 – $25,000 dollars. Now that will vary up or down depending on the size of the room and the selection of finishes, but that allowance should cover most standard size bathrooms.
Below I will give you a real life example of what it costs to renovate or remodel a bathroom by listing out the actual costs of our own bathroom renovation.
Example – Our Ground Floor Bathroom Renovation.
A quick back story – We renovated this bathroom back in 2011 when we first purchased our property, and combined these works as part of our initial freshen up of the existing dwelling before we actually moved in after the purchase. This renovation was done before we started our major renovation back in 2014 on the “Small Space Big Build Project”.
While rates and costs will change over time the below will give you an appreciation of the breakdown of all the costs that can be associated with a bathroom renovation.
Below is a photo of the bathroom before we started work.
Bathroom Renovation Costs – Ground Floor
Demolition – Rubbish removal cost – Skip Bin (note – no labour costs as we did this ourselves) $650.
Plumbing – Run new services including relocating drainage and sewer in the concrete slab, cost also includes the fit off of all new fittings upon completion. $3177.
Electrical – New wiring to services such as heat lamp, exhaust fan, heated towel rail, floor heating and LED strip lights. Cost also includes fitting all of the above items upon completion $1460.
Carpentry – Build wall frames for concealed plumbing, fit toilet roll holders, robe hooks, hang door and fit new lock $1,120
Plasterer – Sheet new wall frame and patch the existing ceiling $720
Waterproofing – New membrane to floor and walls (2 coats) $600
Tiling – Full height wall (3.1 meters) and floor tiling in subway tiles (brick pattern) $2,200.
Painting – Ceiling, window and door Inc frame $940
Cabinetry – Custom made mirrored shaving cabinet, Inc installation $1,850.
Shower screen – Frameless glass unit, Inc installation $1,400.
Materials supplied for the project
Plumbing fittings – Wall hung toilet, taps, basin, 2* shower roses, heated towel rail, under floor heating $3,488
Tile supply – Wall and floor $1,575 (my wife has expensive taste…)
Light fittings – IXL heat lamp / fan and LED strip lighting $650
Door and handle – $240
Miscellaneousness building materials – Bagged concrete, timber framing, tile angles, cornice, nails bolts and screws etc $680
OUR TOTAL BATHROOM COST $ 20,750
Now if we were to factor in what you would pay a builder or bathroom renovation company to take care of this for you, you need to factor in their profit margin.
NOTE – Most builders will apply a margin of between 20% – 30% on top of their contractors and material cost totals to cover their overheads of running the project and their profit. So with the above example 30% on $20,750 = $6,225 Therefore the total would be closer to $26,975.
With all of the above costs laid out, you need to factor in that I am a builder myself and I have good relationships with my trades and suppliers which mean I also get good pricing as well as being very hands on.
In my professional opinion most people would be looking at closer to $30,000 to get the same result as what we have above.
So with the above said do you need a builder to help manage your bathroom renovation? No you don’t, but it will come down to how much time and effort you are willing to put into managing the entire process from start to finish including time on site to trouble shoot and problem solve if needed.
I wrote a little more in detail about some of the essential steps over on the Our Build Blog last year, check this out as well to get some more ideas.
Lastly if you are looking to tackle your own bathroom renovation I will have a video course coming out later in the year to help show all of the essential steps and processes along they way, sign up today if you are interested in knowing more and i will let you know when it is available.
Best wishes, James Mason.
