Bathroom Renovations how much do they cost

Bathroom Renovations – How Much Do They Cost?

According to Canadian Home Trends, an average 5′ by 10′ bathroom in a home will cost anywhere from $10,000 to $16,000. That figure includes the designing, planning, supplies, and installation. If you are renovating a bathroom in a condominium, you could expect to pay about 30% more because of the restrictions imposed by condo rules and existing building design. Therefore, renovating a condominium bathroom could cost from $13,000 to $20,800.

Part 2: The Flooring

It’s difficult to give you an exact number when it comes to flooring costs for your bathroom. That’s because the final numbers will depend on a number of factors including:

  • The type of flooring you choose
  • Whether or not your sub-floor needs repairing of replacing
  • Removal of your existing floor covering
  • The size of your bathroom

To give you a better idea about how much you should expect to spend on flooring for your bathroom renovation, we’ve broken down the costs into separate sections. The numbers quoted come from Danny Edell of Toronto-based boutique construction and renovation company True Contractors who put these figures together for HGTV.

Some Helpful Terms

When discussing flooring you may come across some terms like floor covering, finish floor, underlay, sub-floor and joists. The following will give you an idea of what each of these terms refers to.

Floor Covering or Finish Floor

The floor covering is the layer of flooring that you actually see and walk on. It can be changed and is not a requirement for structural support, however, it often provides supplementary support. When you remove the floor covering, you should find the real structurally supporting floor beneath. This is known as the substrate and it is your permanent floor. It consists of possibly an underlay, sub-floor, and joists. Some of the more common floor coverings include:

Floor Underlay

Underlay is a thin material that’s sandwiched between the exposed flooring (the part you can see) and the sub-floor. This layer is optional and its purpose is to provide a smooth, consistent surface for the floor covering. Different flooring covers require different underlay. The following are common flooring/underlay combinations:


A sub floor is a thick flat surface that the other floor layers, the underlay, and the top floor, rest on. It is the layer of flooring that is directly connected to the joists. It is usually made from plywood or OSB (oriented strand board) and can be anywhere from 19/32″ to 1 1/8″ thick. The sub-floor is very important as it is a structural, not a cosmetic, component. If you have a concrete slab floor then the slab itself may be the actual sub-floor.

To get a better idea about what a sub-floor looks like and how it is installed, watch the following video.


Joists are a structural component underneath your sub-floor. They support everything above them. They are made from engineered wood, laminated wood or dimensional lumber. All of the flooring in your home has joists except for those that are concrete slabs.
