The cost to paint the interior of a house varies depending on the number of factors. These include the overall dimension of the room (e.g. ceiling height, room width), number of doors and windows, trim work, paint supplies and many others.

As first-time homeowners (or renovators), it helps to get an overview of the estimated cost to organise your finances. The average cost to paint the interior of a house is around $10 to $30 per square metre. You can expect to pay more than the given range depending on the pre-painting procedures included in the requirement.

How much does interior painting cost?

If, for instance, preparation, cleanup and finishing touches are part of the work, that’s a different computation. Likewise, applying a few enhancements on the interior walls, trims and ceilings can add to the cost. In that case, a qualified painting contractor can charge clients around $30 to $40+ for extra paint application and service. This may include adding textures (e.g. sponge painting) to your simple-looking wall.

The lowest amount covers a single colour and undercoat with one to two finishing coats for the interiors. However, higher demands account to higher costs. It will depend on the job difficulty, variety of colours required and other inclusions (i.e. painting materials supplied by the contractor).


On average, the price can start from $250 to $400 if you plan to have only one room painted. However, it will still depend on the room size and other details such as the contractor’s conditions indicated in the contract.

  • For painting two-bedroom house, expect the price to be around $500 to $1,200
  • For painting three bedrooms, the interior painting job can cost around $6,500 (inclusive of project materials and service)

Note: The cost to paint three bedrooms can possibly go lower than tackling a single room in one service. In this case, it’s better to plan for your interior painting project and have it serviced altogether to save you money.


Price estimates for a standard bathroom painting can play around $200 to $300. The cost covers drywalling and painting on walls and trims.

If you have two bathrooms to deal with, you may get discounts or a lower price range based on the agreement of both parties.

  • Drop cloths (to protect floor systems and other furniture)
  • Paint, primer and finishes
  • Paint stirrers, brushes, rollers and refills
