How Much Does Bath Installation Cost? - Written by Graig Gibson

Bathtubs/Renovation Costs 

If you have a perfectly serviceable bathroom, but your bath is sorely in need of an upgrade you could swop this out for a new one. You may also want to update to a stylish freestanding model or spa bath, which are all the rage. In terms of the practicalities, replacing a bath typically will involve the services of a number of trades, including a plumber, waterproofer, and/or tiler - unless you are going to use a dedicated bathroom renovator.

But how much is this going to cost? Before we get into the nitty gritty of the cost of this project, what type of bath are you going to go for?

Types of Baths

Besides the option of freestanding or built-in style bathtub, there are a number of materials used in the manufacture of modern baths - all at different price points and with their own pros and cons. These include:

  • Acrylic - an affordable, durable & versatile material
  • Cast iron - mid price, and when enamelled this material is a durable classic
  • Fibreglass - flexible and affordable but can scratch
  • Metal - designer option and costly
  • Polymer - versatile composite of materials, mid price
  • Steel - lighter than cast iron, mid price
  • Stone - high-end option, durable and stylish

Using a licensed tradie for your project

It is imperative you utilise licensed trades if you are renovating your bathroom. All aspects are critical to the structural integrity of this space, particularly the waterproofing which is also a legal requirement.

Hiring the right tradie for your bath installation

When it comes time to hiring a tradie, make sure they are right for your job. Some questions to ask them include:

  • Are you licensed?
  • Are you insured to work in my home?
  • How long will my job take?
  • Can you provide a written quote?
  • Do you have references I can follow up?
  • Can I see examples of your work?

#hiptip:  Always ask if your tradie is licensed for the job they are quoting for!

Once you have chosen a bathtub you need to find a service to carry out the job for you. Initially you need to decide if you are going to use a dedicated bathroom renovation service. The advantage of this is that they have all the relevant trades to hand and will take care of everything. The alternative is for you to source all the individual licensed trades your job requires. These may include a:

Plumber:  a plumber will be able to remove and install a bath, including altering or modifying any necessary fixtures and/or drainage.  Plumbers charge in the region of $100/hour, depending on where you live and there may also be a one-off call out charge.

Always use tradies who are licensed for your bathroom reno!

#hiptip: Always use a licensed plumber to carry out any work on your plumbing system!

Waterproofer:  even though your bathroom was initially waterproofed, ripping out an old bath and altering fixtures is likely to require fresh waterproofing. There are regulations governing the extent of waterproofing in bathrooms. A professional waterproofer will ensure your job is done to spec. Some states require a waterproofer to be licensed and/or issue a statement/certificate of compliance.  Expect waterproofing to cost anywhere from $35 to $70 per square metre, depending on the materials utilised.

Tiler:  your new bath is unlikely to be a like-for-like replacement so you will need a tiler to make the area like new.  Expect to pay in the region of $60 per square metre for bathroom tiling - with the type of tile and the scale of the job the determining factors.
