How it works

Our bathroom contruction cost calculator estimates the cost of bathrooms by adding labour costs to the cost of fittings. Labour includes the cost of installing waterproofing, plumbing, tiling, electrical items, gyprocking, painting and the installation of fittings.

The per-square-metre cost for labour that we use is $1100 for a new home and $1600 for a renovation (renovations require the old bathroom to be gutted). We obtained these values by getting prices from various bathroom installation specialists and then taking an average.

If your project is a bathroom 'makeover', rather than a full renovation, this calculator can help you estimate the cost of new fittings.

Step 1: Initialise the calculator

Click on small, medium or large to set-up some initial values. The default selection is medium. You will be able to set your own bathroom size in the next step.


Small - 6.48m2


Medium - 7.68m2


Large - 10.24m2

Step 2: Select renovation or new home

Are you replacing an old bathroom or adding a bathroom to a new home? Select 'renovation or 'new home'. Renovation is the pre-selected default. Note: You can also set your own value.

Step 3: Adjust bathroom size & tiled area

Make adjustments to the sizes below to match your bathroom plan. Floor tiling often takes up almost 100% of the bathroom's area. Wall tiling area varies and will depend on your design. Typical arrangements for wall tiles are - skirting tile only, 1.8 metres high and all the way to the ceiling.

Size of bathroom:

m2

Tiled area (includes floor & walls):

m2

Step 4: Select your budget & fittings

First set some default values

The custom button clears all prices so you can enter your own. The other three buttons set default prices that reflect your budget. You can change these prices afterwords. Default prices were obtained by researching the prices at Bunnings and Bathroomware House.

     

Then adjust the default values

Adjust the prices shown below to reflect prices you have been quoted online or elsewhere.

Use the button to be taken to a web page with prices for the selected fitting.

Tips for designing & specifying your new bathroom

Concrete flooring in the bathroom

Flooring options

Most bathrooms are tiled, but keep in mind there are more flooring options. If you believe the per-square metre costs shown above are unrealistic specify your own value. (And don't forget the walls!).

Other flooring options:

  • Polished concrete
  • Rubber
  • Timber slats
  • Tiles - If you're on a budget, only tile where you need to, don't tile all the way to the ceiling - this is an expensive option. Your bathroom will still look great and will also be affordable if you just install a tiled skirting (one row of tiles up the wall).

Matching your bathroom items

General tip - When choosing taps, robe hooks and other items in the bathroom try to stay with the same style so everything matches. See our article Choosing better Bathroom Fittings for more information.

Baths & spas

Baths & spas vary in price depending on what materials they are made of, brand name and installation requirements. A basic bath could be an acrylic recessed bath notched into the stud wall. A standard bath can be acrylic or enamel steel that sits in a tiled "hob". A premium bath might be a free standing steel bath with a matching "skirt".

Tap sets, mixers and spouts

A mixer is a single tap and spout item that delivers hot and cold water. Separate tap and spout sets are called either shower, basin or bath "sets" and are generally more economical than mixers and have less moving parts - thus less problems.

Basins

The basin is usually bought alone, without the tap and spout and can come in a few different options.

  1. Basic - Vanity basin - recessed into the bench.
  2. Standard - Semi-recessed - basin protrudes slightly from the bench top.
  3. Premium - Wall hung or pedestal (no bench top or vanity required).

Mirrors

A fixed mirror is the most economical option. Cabinet mirrors include a shelving unit behind the operable mirror and cost more than a fixed mirror.

Shower enclosures and shower screens

There are three general types of shower screens. They are:

  • Basic: made from thin glass panels with large section aluminium extrusions.
  • Standard: semi-frameless using slightly thicker glass panels with less thick aluminium extrusions than the basic type.
  • Premium: frameless shower screens - these have no aluminium frame to support the glass but the glass is quite thick - the screens are attached to the wall with chrome brackets.

Shower rail

A shower rail is a shower rose and hose combination that attaches to the wall via a vertical rail made of plastic with a chrome finish or stainless steel.

Exhaust fan

The basic bathroom exhaust fan will draw moisture from the room. A standard unit may also have a light. A premium fan should have a heater. If you have a well ventilating window and live in a warn climate you should not need an exhaust fan.

Floor wastes

Bathroom floor wastes have come along way in the last few years. Here are a few options:

  • Basic - chrome - You can still buy the regular round chrome floor wastes.
  • Standard - concealed - Concealed floor wastes are square or round in shape and are designed so a tile can be inserted into the top - hence concealing the floor waste.
  • Premium - trough - Floor troughs are so very cool... they are made to order and are generally about 900mm long and 100mm wide and deep. They have a stainless steel grated top finish or a concealed option and represent the "top end" of floor wastes when renovating.
