Bathtub Installation

  • A bathtub in your bathroom is a sign of luxury and comfort. As per your needs, you can choose a corner bathtub, clawfoot, drop-in or flat bathtub. Based on the size of your bathroom, a contractor will be able to guide you on which bathtub to choose. It may cost you around $250 to install or replace a bathtub in Oshawa.

Faucet Installation

  • Old and rusty faucets can bring down the shine of your bathroom. You can receive contaminated water from rusty faucets and they can often create water puddles with small leaks. Replacing them with new and trendy faucets with the help of a professional will cost you around $240.

Sink Installation

  • There are different types of bathroom sinks. Based on your requirements and needs you can choose an under-mount sink, a wall-mounted sink or a vessel sink. If you wish to add a small cabinet below or above the sink, the type of sink you choose will change. A bathroom renovation specialist can introduce you to different types of sinks and help you make the right decision. It may cost you up to $1,500 to install a sink in Oshawa.

Shower Installation

  • Adding a beautiful glass shower stall can give your bathroom a modern look and prove to be a space saver. Shower installations include new floor, glass and installing new shower accessories. Excluding all the material costs, it may cost you approximately $4,000 to install a new shower stall.

Tile Installation

  • Based on the type of tile you choose for the bathroom, the cost of the project and the timeline will change drastically. Just like a sink installation, a professional contractor can help you choose the right non-slip tile for your bathroom. After measuring the area of your bathroom, the pro will be able to give you a budget and timeline estimate to complete this task. It may cost you $7,500 on average to replace or install new tiles.

Toilet Installation

  • Installing a toilet can be a difficult task as it needs to be connected with a water source and drainage line. Even the smallest gap in these connections can result in huge water-related damages. An expert installer can help you install and assemble different toilet parts without any damage. It may cost you around $587 on average to install a toilet.

Whole Bathroom Renovation

  • A whole bathroom renovation is a complete change of your bathroom from floor to ceiling and wall to wall. This includes replacing drywall, installing new bathroom fixtures like sink, toilet and bathtub, adding new furniture and light fixtures. A whole bathroom renovation is ideal if you’re trying to convert the powder room into a small shower room or adding a guest bathroom in the basement. Considering the number of tasks it involves, it may cost you up to $50,000 for a whole bathroom renovation.

Factors Impacting Bathroom Renovation Costs in Oshawa

Size of the Bathroom

  • There are three common types of bathroom sizes based on their dimensions: master bathroom, guest bathroom and small bathroom.
  • Based on the size of the bathroom, the cost to renovate it will change based on the dimensions. Be it converting a powder room into a small 3 piece bathroom, expanding the current bathrooms or just renovating them completely, a contractor will measure the size and then give you a cost estimate.

Number of Tasks Involved

  • There are two types of bathroom renovations: partial and whole. The tasks involved will vary as per your requirements and the more tasks you add, the more it will cost.
  • If you want to renovate or replace some parts of your bathroom such as a new bathtub, sink or flooring, then it will be considered a partial renovation. Whereas a whole renovation is a complete transformation of your bathroom from walls to ceiling, changing or replacing every single thing.
  • Doing a whole renovation is always ideal as you can plan and execute everything in one go. You won’t have to invest in renovating year after year, the design will be consistent and all the mess will be cleared in one go.
  • Based on your requirements, a bathroom renovation specialist in Oshawa will help you decide whether to opt for a whole bathroom renovation or partial.

Moving Plumbing

  • Moving or re-routing the plumbing is common for large fixtures like bathtubs and shower stalls. Beneath every bathroom floor, there is a plumbing joint that should not be damaged to avoid any drainage issues.
  • A bathroom renovation specialist will be able to reroute the plumbing with the help of an electrician and plumber in their team. These technicians will make sure that any electrical wires or previous plumbing fixtures beneath the floor or behind walls are not harmed. Based on the scale of the moving, the whole plumbing reroute can cost you heavily. The best way to avoid any damages is to hire a professional to reroute the plumbing.
  • You can save a significant amount of money by opting to keep your plumbing fixtures in place.

Step by Step Guide to a Whole Bathroom Renovation in Oshawa

Step 1: Make a List of Tasks

  • Start by making a list of all of the changes you would like to make in your bathroom. List all the small changes from replacing a socket to adding a shelf. Be sure to include big changes like removing your tub and adding a shower. Share this list with your contractor as it will help them provide you with a time and cost estimate.

Step 2: Cleaning and Demolition

  • Any replacement procedure in your bathroom requires the removal and demolition of existing fixtures. This process can create a lot of debris. Even after removing heavy fixtures like flooring or drywall, the contractor will be required to clean the area to clear some space for new fixtures. It is important to fix new bathroom equipment on a clean surface for their longevity.
  • A contractor will make sure to demolish only the specific areas which require replacement or repair. If you plan to do it yourself and damage any crucial parts accidentally, it may cost you heavily getting those repaired.

Step 3: Install or Repair Drywall, Ceiling and Flooring

  • Be it a whole renovation or partial, repairing and installing the basic structure of any bathroom is a delicate yet heavy task. A professional can replace drywall, add a new ceiling and flooring with minimum possibility of damages.
  • You can choose a colour palette for your bathroom and a specific type of flooring, the contractor will do the rest of the job. Depending on the size of the bathroom it may take 24-48 hours to complete this step.

Step 4: Bathroom Fixtures: Electrical, Plumbing and Furniture

  • After renovating the structure, the next step is to add all the fixtures and layers to your bathroom to make it more user-friendly. Here again, the contractor will employ multiple professional plumbers, electricians and carpenters to install various fixtures.
  • This includes plumbing fixtures, electrical fixtures and furniture installation:

| Plumbing Fixtures | Bathtub, sink, toilet, faucets, shower stall | | Electrical Fixtures | Lighting, sockets, heated floors | | Furniture Installation | Cabinets and shelves |

Step 5: Final Clean Up

  • No matter if you’re replacing or installing brand new fixtures, there is always a mountain of debris to clean up after.
  • A professional contractor will clear up all the debris and mess, clean the renovated surfaces and leave you with a sparkling new bathroom that is ready to use.

Important Facts to Remember

  • These steps provide you with an overview of how the renovation process works. Based on the size of your project, number and type of tasks involved, your desired timeline and budget, these steps may change. A bathroom renovation specialist can provide you with a customized execution plan to successfully complete your renovation.
  • Various tasks of the renovation project require different technicians like plumbers, electricians, carpenters and cleaning services. Hiring each technician independently, coordinating with them and managing a huge team coming in and out of your bathroom at all hours can be a planning disaster. You can end up with a botched up job, heavy bills and an extended timeline. If you hire a bathroom renovation contractor, you won’t have to worry about any of this. Contractors employ these technicians in their crew and manage them with professional skills as per the execution plan for your project.

Toilet Installation

It seems to me it would be simple to remove the old toilet and put in a new one. Do we really need a plumber to do it?

Is it okay to tile over existing tiles or should I take them out first?

Anonymous user 18/11/2025 - 9:41 AM

I’m planning a bathroom renovation and was wondering if it’s okay to install new tiles directly over the old ones or if it’s better to remove them completely first. The existing tiles are in decent shape and still well stuck to the wall, but I’m not sure if tiling over them would cause problems down the road with weight, adhesion or moisture. Has anyone done this? And what would you recommend?

What order should I follow for a bathroom renovation?

Anonymous user 18/11/2025 - 9:38 AM

I've got a small L-shaped bathroom that I want to remodel and I'm also planning to move a wall back by about 30 centimeters to make the room more square. I'm totally stuck on figuring out the order of everything because I need to find the right tradespeople. This is our only bathroom so I need it to be out of commission for as little time as possible. It feels like I need multiple people to handle everything, which makes this confusing, especially for such a tiny space! Here's what needs to be done: - Remove the tiles - Take out the bathroom fixtures - Replace the window in the outside wall - Install a ventilation fan in the external wall - Move the internal stud wall - Do all the plastering - Put in the new fixtures - Tile the bathroom - Install new lights What order should all these be done in? And who should I hire for each job?
