Bathroom Renos updated our basement bathroom (Dec 2025), gutting it down to the studs, replacing moldy drywalls, retiling the shower, floor and backsplash. They worked with us to re-use the existing sink and toilet. Nestor was very helpful and assisted us with choosing the tiles and the quantity. His staff was detailed in the work and we're very happy with the result and Nestor would show up frequently to inspect the work. We were so pleased, we asked him to install a bathroom fan on our main floor washroom. Thanks Nestor and team.

Nestor and his team at Bathroom Renos fully renovated our bathroom in January 2025. From our first meeting through completion of the work everyone involved was professional, courteous and responsive to our requests, ideas and on-the-fly adjustments to the project plan. The crew took great care to ensure the work space was kept clean and tidied up at the end of each day. The finished bathroom is both beautiful and a joy to use. Bathroom Renos deserves a 10/10 for exceeding our expectations.

With recommendation from neighbours, we arranged for Bathroom Renos to quote and ultimately chose them to fully renovate our main bathroom. Nestor gave us a very competitive quote and was very accommodating on schedule and provided good ideas on designs and supplier recommendations. The work Nestor and his team performed was excellent with great attention to details. I was also pleased that they installed proper waterproof membranes and backer boards in our new walk-in shower. Each day they put out mats to protect floors throughout the home and ensured the working area was clean and neat. During the project, we made a few minor changes and improvements and Nestor was always happy to oblige our changes. When the job was completed, we liked the work so much that we had his team come back and renovate our basement bathroom to install a deeper tub with new tile. Nestor was very engaged on a daily basis throughout our entire project and was quick to deal with any surprises or issues we encountered. And most importantly, he stands by his work and has graciously returned to support a minor warranty issue we encountered. We highly recommend Bathroom Renos to our friends and family who are also considering him for their projects.

Nestor and his team are amazing. We asked them to replace a leaky shower in November 2024. Our new shower looks great, and the whole process was quick and easy. The entire crew was professional and friendly. I highly recommend them!

Nestor and his team are really good at their craft. Not only that, they are really good at estimating how much it will cost as well and also give you options you can choose from depending on your budget.

We had our bathroom renovated a bit, with shower floor tiles changed and they did a great job with sealing the floor first, proper grout and making the floor tiles properly working so the water does not accumulate anywhere.

The suggestions they made for which tiles to get depending on our needs also worked so well. Finally, we needed a support bar installed and that is also done right to the measurement.

10/10 will hire them again if and when we need to.

Nestor has done many projects, large and small, for us over the years. The quality of his work is consistently exceptional. He did a makeover for our basement bathroom with a freestanding tub, shower with a sliding glass door, new sinks, vanities and extra storage. It looks like a high end hotel bathroom. Gorgeous!

We had our 1980's bathroom renovated by Nestor/Bathroom Renos in August 2024. We were very satisfied throughout the entire process with the level of communication and collaboration for the project. Nestor was responsive, organized, helpful and the level of professionalism (and cleanliness on the job) was 10/10. We were also extremely happy with the reno itself and are loving our new bathroom!

Nestor is amazing. Would highly recommend him and his team to anyone looking for a trustworthy contractor with excellent communication and fantastic results.

Two months ago we hired Nestor and his team to do a major bathroom renovation repairing a hole in the floor, tiling the floor, walls and shower enclosure, installing an exhaust fan (which required making a hole in the wall of the house) and new toilet, vanity and taps. Every evening the workplace was cleaned up and all equipment and tools were tidied. The workmen were quiet, polite and never intrusive and Nestor himself was attentive and very helpful at resourcing all the extra hardware needed (tiles, hinges, etc.). All the work was completed on time and within the budget estimate. It was all very professional and we were very pleased with the final results.

Nestor and his team worked on my ensuite washroom in less than 10 days! We had issues with the shower leaking into the surrounding wall so the project required a lot of internal repairs as well. Not only did they restore the internal structure, but they also upgraded the whole washroom with a more modern look that included marbled tiles and a pristine glass shower door. They were so professional and also very considerate of my home. Even after the work is done, they sweep the floors, vacuum and even POLISH the floors!! Would definitely use this company again for future projects.

Thank you so much Nestor. You and your team have done a wonderful job and you’ve been so easy to work with. Nothing has been too much trouble and your team is tidy, respectful and skilled at what they do. It’s been such a pleasure to work with you on this and the transformation from a tub shower that my 94 year old Dad was unable to use to a shower that is now safe yet stylish, is just perfect. 🤩
Response from the owner:It's been a true pleasure assisting you, Debbie, and we're thrilled to hear that both the transformation and our accommodating team have exceeded your expectations, making your father's shower both safe and elegant.

We had our main bathroom renovated and our second bathroom made fully accessible by Nestor and his crew. This was a complicated job in that we needed one accessible washroom throughout the work. Nestor had given us the most reasonable and transparent quote, and we were impressed by his professionalism, kindness and clear communication. During the project (which was finished as quickly as humanly possible), we were bowled over by the skill and hard work of his crew. The main washroom (gutted and changed from bathtub to walk-in shower with all new tile) is beautiful and feels larger with the new design, along with tile to the high ceiling. Nestor's crew members did careful, meticulous work and were consistently thoughtful. The tiled bench at the back of the shower was itself a tricky project, but we've found it drains well, is very useful and looks amazing. And after the job was finished, when one of the toilets rocked a bit, Nestor came out that day to fix it, making his guarantee for the work quite clear. Overall, this was the best work we have ever had done on any renovation, and we will always recommend Nestor and his crew as top professionals. I only hope he's open to doing other types of improvements for us!
Response from the owner:Thank you so much, Sheryl, for your wonderful words! We’re grateful for the chance to renovate your main bathroom and make your second washroom fully accessible. It was a pleasure transforming your bathtub into a walk-in shower and we’re thrilled you’re enjoying the custom bench. We take pride in offering transparent pricing, clear communication, and reliable service for bathroom renovations across Toronto and Etobicoke. Knowing you’re happy with both the design and functionality means the world to us. We’d be honoured to help you and Alan again with future home improvements!

Frequently Asked Questions

Bathroom Renovations in Etobicoke — FAQ

Several factors influence overall cost, including bathroom size, whether plumbing or electrical lines need relocating, and the quality of fixtures, flooring, and tile. Custom features like glass shower enclosures, heated floors, or luxury vanities also affect pricing. A mid-range renovation in Etobicoke typically runs $15,000–$30,000, while a full custom renovation with premium materials and layout changes can range from $30,000–$50,000+. For the most accurate estimate, we provide a detailed, no-obligation in-home consultation.
A standard bathroom renovation usually takes 2 to 4 weeks to complete. A simple tub-to-shower conversion may take less time, while a full remodel involving plumbing, electrical, tiling, and custom finishes will take longer. We provide a realistic timeline during your consultation and communicate progress daily throughout the project.
Set a realistic budget early and stick to it. Invest where it matters most — waterproofing and plumbing — and save on areas like fixture finishes or tile styles where durable alternatives exist. Request a detailed written quote, avoid last-minute changes, and source cost-effective but durable materials. Our transparent, fixed-price quoting means the number you see is the number you pay — no surprises mid-project.
We serve homeowners across all of Etobicoke, including Mimico, Long Branch, New Toronto, Alderwood, The Kingsway, Islington Village, Humber Bay, Princess Gardens, Markland Wood, and Eringate. From our base at 254 The Queensway, we also serve Toronto, Mississauga, and the wider GTA. If you're unsure whether we cover your area, give us a call at 416-220-6423.
Schluter Kerdi is a professional-grade waterproofing membrane system applied directly to the substrate, with tile set on top using thin-set mortar. Unlike old-style PVC liners that trap moisture beneath the tile and cause hidden rot, Kerdi creates a continuous, vapour-tight barrier with no gaps for moisture to accumulate. We install it on every shower and wet area we build — no exceptions. It's the difference between a shower that starts failing in 5 years and one that performs for 25+.
