Are you wondering how to renovate a bathroom? Bathrooms are not just about bathrooms anymore.

Renovating a bathroom can be as simple as changing out towel rods and faucets for new ones, or as complex as knocking down walls and rearranging tubs and toilet. However, one of the most used fixtures and the primer decorative item in your bathroom or ensuite is the vanity.

Before you can begin your DIY bathroom renovation, you will need to plan it out. The more work you do at the planning stage, the easier it will be to carry out your plans once you move on to the next step.

Plan the Design and layout

Decide how you want the bathroom to look like. The design of your bathroom renovation is one of the most important elements of the project.

Think about what mood, theme, and colour scheme you want. The design you choose for your renovation should be based on your personal preferences, what aesthetic and design elements you think will look best in the space, and the budget.

As bathrooms are generally small rooms, it's important to design a layout that maximises the space available. Start by collating the essential information, and get your quotes: measure up your bathroom and design a floor plan, then find the tradies you’ll need; like tilers, carpenters, and plumbers etc.

The most common design elements you should definitely decide upon before you start your bathroom renovation are:

  • Colour scheme: what colours will you use for your bathroom renovation? Make sure that all of the elements of your design work together in terms of the colour scheme. If your bathroom is beginning to show signs of wear and tear, this simple upgrade will revitalise the space and give the impression of a fresh bathroom makeover.
  • Theme: such as modern, contemporary or coastal. Write down things that might go with that theme, such as rustic wood, lighthouses, others.
  • Fixtures: will you need completely new fixtures in your new bathroom, such as showers, sinks and tubs? If so, how many fixtures do you plan on replacing? Knowing this will play a large part in creating your budget as well as helping you decide on other aspects of your budget.
  • Storage: will you be adding storage space during your renovation? You will also need to find replacements for any areas of the bathroom that you’ve renovated by removing storage options, such as removing bathroom closets.
  • Lighting: make sure you have adequate lighting in your bathroom. Review how much natural light your bathroom windows are currently providing, then decide the type of lighting you require.
  • Heating and ventilation: there are several heating options in bathrooms, but the main heating solutions are heated towel rails and underfloor heating.
  • Utility: Where are the utilities in your bathroom located? Specifically, where are the electrical wiring and plumbing pipes in your bathroom located?

Define how much work needs to be done

Determine the scope of your ideal bathroom renovation. There are different types of renovations, and each requires a different amount of work, money and time. Some renovations may also require the aid of a trained professional, for which you will need to hire a contractor. You could choose between three main types of renovations:

  1. Basic Bathroom Renovation
  2. Mid-Range Bathroom Renovation
  3. High-End Bathroom Renovation

Consider this short list of things for your bathroom renovation:

  • Floor tile, tile bed, and grout
  • Shower/bath tile, tile bed and grout
  • Sink faucet
  • Showerhead and fixtures
  • Paint
  • Vanity cabinet or Mirror Cabinet
  • Mirror
  • Towel bars and hooks

Remodels accrue unexpected costs along the way. You will plan for this. So deduct 10% from the number you wrote on the paper. This is the dollar amount you can actually spend.

Define a budget

The more you plan on doing to your bathroom, the more money you will have to spend. After your floor plan is done, then comes research, and getting all the important quotes. Highlighting a single focal point in your bathroom to feature your style takes the pressure off the budget, as you put your money into a small area. This might be a floating vanity and splashback tiles and a coloured vessel basin, or mosaic on a shelf wall.

A complete bathroom renovation can involve a number of different trade specialists from plumbers, tilers, electricians, plasterers, painters, waterproofing specialists and more.

One of the most common ways to blow out your budget is by choosing everything separately. It also makes keeping track of your overall budget harder, and you end up spending far more than you intended.

The cost of a complete bathroom renovation will depend on several factors, including:

  • The size of the bathroom
  • The fittings selected (toilet, bath, sink etc.)
  • The materials, the quality of materials and products used (tiles, paint, etc.). Choose moisture and mildew-resistant paint.
  • The scope of plumbing, electrical work and other installations
  • The addition of luxury elements such as heated flooring or heated towel racks
  • If there will be new or moved ventilation systems such as an exhaust fan

But timelines in renovation can be off because of delays in supplies, unexpected conditions behind the walls, delays from subcontractors or even unexpected conditions.
