We had trouble finding the click vinyl flooring we wanted at the big box stores in Trenton and Belleville, so we were very happy to find a great selection here. We got the Floorest Canada "Kasane" colour SPC Luxury Vinyl Flooring and are very happy with the choice. We found the store personnel to be very friendly and helpful. We ordered it and it came in within about a week.

What a great discovery this store has been! We first visited the Ottawa location and then began researching our options online, particularly for flooring. We are building in Picton and in one visit to the Belleville location we were able to purchase our flooring, subfloor materials, bathroom vanity and faucet, all interior doors, door hardware, and trim. Liam assisted us and he was so knowledgeable, patient and thorough. He knows all the products inside out and asked clarifying questions to make sure we were making the right choices. He was our trusted consultant, much more than an "order-taker"! Their prices cannot be beat and all the staff are so helpful and go above and beyond. My husband and I highly recommend Belleville Cosmaroma. Thank you Liam!

I am the owner of Classic Home Improvements.
I was introduced to the Cosmaroma Bellville store
By one of my customers. This store is second to none. The customer service is remarkable. The product selection is endless and the prices are unbeatable. If I lived closer, I would be there daily.
Pay them a visit, you will thank me.

This is the place to go for all the flooring and tile that you need for your home as well as other items within your home. All at great prices as well. The staff there, in the Belleville store, are so helpful. Thanks goes out to Dave, Liam and the two women at the front counter. Liam took the time to spend and inform us to finally decide which to chose. This is pics of our new bathroom shower and floor, as well as the kitchen floor! Cosmaroma Belleville is the place to go!
