We have been a client of OTC for a while now and have been sending clients to their store for selections. They have a wide variety, which would please any client. The entire staff is friendly and helpful and always assist us and our clients with any questions and queries. I would recommend OTC to all (builders and DIYers). 5 star service.

Was renovating my bathroom and have always noticed OTC tiles on Canterbury Rd as they have a massive collection of tiles so decided to check it out. The tile I was looking for was not on display but a helpful assistant managed to find it within their non display collection. Their pricing was also most competitive out of all the other quotes I had recieved. Fast service, efficient delivery and knowledgable staff. Would use them again if the opportunity came up.

We recently renovated our bathrooms and kitchen, with the consultation of Ryan and the team from OTC, the shopping and selection process for all our tiles and bathroom requirements was a pleasant one as they provided helpful professional advice, patient answering all our questions, overall excellent customer service in all aspects of our renovation journey. Pricing was also amazing and very competitive. Very satisfied and will come back!

We did a major full home renovation last year winter. We had our tiles, bathroom fixtures, vanity, toilets, shower screens, sinks, etc. all from OTC. We had a wonderful shopping experience with Ryan at OTC. He is very responsive to all my emails and msgs. We really appreciate his honesty, knowledge, and generosity. We definitely would recommend them to any of our family, relatives and friends, and anyone who is looking for a reliable supplier. You wouldn't disappoint with their services and products. I would return to them in the future for our next project! Highly recommend.
