Frequently Asked Questions
What budget should I set aside for my bathroom renovation
The cost of bathroom renovation can vary significantly based on several factors, including the size of your bathroom, the quality of materials chosen and the complexity of the work involved. While a simple bathroom can be renovated for as little as $19,000, you can expect to pay between $25,000 and $35,000 on average for the complete renovation of a standard bathroom. For a higher-end bathroom, costs can easily reach $50,000. According to the National Bank, the maximum cost of a bathroom renovation is estimated at 5% of the value of your property. This means that for a $650,000 property, you should invest at least $32,500. For a more accurate estimate, let’s schedule a consultation so that we can discuss your specific needs and preferences.
How long will the renovation take?
The time needed to renovate a bathroom depends on the project scope. A simple refresh with new accessories and paint can take as little as 7 days, while a complete renovation with structural changes and high-end finishes can take 2-3 weeks. It’s also recommended to allow a few extra days for unforeseen situations, which are not uncommon in renovation projects. We’ll provide you with a detailed timeline upfront, including key milestones, so you can clearly understand the project’s progression.
Do I need a permit to renovate my bathroom?
The need for a permit depends on the scope of the bathroom renovation. Minor renovations, such as painting or replacing fixtures, generally don’t require a permit. On the other hand, more extensive work, such as plumbing or electrical modifications, structural alterations or enlarging the bathroom surface area, requires a permit. After assessing the specific requirements of your project, we’ll help you obtain the appropriate permits to ensure that everything is up to code.
Can I continue to use my bathroom during the renovation?
In most cases, a complete bathroom renovation means the space will be out of use for the project’s duration. If this is the only bathroom in your home, we recommend that you plan a temporary replacement solution. At our first meeting, we can discuss the details of using your bathroom during the renovation and the potential impact on the work schedule.
Will a bathroom renovation add value to my property?
As many sources say, bathroom renovations add value to a property. As a homeowner, you can expect a return on investment of 65% to 100% of the cost of your renovation ( in addition to an improved quality of life!).
How do you deal with unexpected changes or problems during renovation?
Unexpected changes and problems are not uncommon during renovation projects. As your bathroom renovation contractor, we handle these situations with clear communication and flexibility. If you request changes, or if we encounter unforeseen problems (such as hidden water damage or structural issues), we’ll immediately discuss the implications for schedule and budget.
