There are a few glaring signs that scream it's time to start that bathroom project you’ve been putting off for years. When you see mould starting to grow, linoleum lifting, and a toilet that flushes 13 litres with each use, there’s no denying you better roll up your sleeves and get down to work.

But where to start? The most important step to any renovation, including in bathrooms, is to have a well thought-out plan in place before starting a demo. So put down the hammer, pick up a pencil and start planning. 

What do you have to work with?

Take note of the space available. Does the shape work well for you? Is there a closet that can be removed to add a bit more space? Just remember: there are a lot of “things” hidden within bathroom walls – such as plumbing stacks, water lines, return air ducts, and electrical wiring – that may impact what you can or can’t do.

So before you get too far into your new bathroom layout, start exploring the locations of electrical, heating and plumbing lines. The best way to do this is to note the outlet and lighting locations in the bathroom and in adjacent rooms. You’ll also need to explore heating and plumbing units from your mechanical room.

Ensure you record all this information by drawing it out on graph paper or on the computer. The drawing needs to include your existing bathroom layout, the location of all the “things” and the dimensions of both.

What do you want?

Now consider both your needs and wants. For instance, will you replace the tub with another tub, or would you prefer a stand-alone shower instead? First draw up your new layout, taking note that fixtures typically come in standard sizes or have required clearances.

You can choose to have more custom selections too, like a tiled shower that can be any size or shape versus an acrylic shower that must fit into a given space. Don’t forget to plan out where you need to have lighting and power in the bathroom. Next start building your product and materials shopping list. Think about how well they will clean, hold up to moisture and wear over time. A bathroom is a harsh environment so select carefully.   

One option to consider if you’re having difficulty imagining a new space is to have a 3D drawing of your bathroom completed. There are countless benefits to using a 3D design option:

• It will show you what the space will look like before you start any work.
• It ensures all decision-makers in the process are agreeing to the same renovation.
• It helps you plan out the bathroom considering all 3D components, not just what you see on a floor plan.
• It helps you visualize how all the materials will look together.  
• It saves you money during the construction phase since you won’t be rebuilding elements multiple times trying to get the right look or function.

There are a few options available to complete a 3D design. If you are computer savvy and want to try your hand at doing it yourself, there are various programs as well as apps to try. Your other option is to hire an interior designer.

It is essential to plan smart with a solid design in place before you pick up the hammer and drill to start a bathroom renovation. With a smart plan you will have a drawing layout (floor plan), electrical drawing, 3D design, product and material shopping list and a confirmed budget. This plan will eliminate a lot of the stress that comes with any renovation.
