Customer testimonials
I recently purchased the Gladstone model from Tasman Saunas, and it's truly exceeded all my expectations. This 6-person barrel sauna, beautifully crafted from Canadian Red Cedar, is not only a stunning addition to my outdoor space but also a powerhouse of warmth, consistently reaching temperatures of 85+ degrees Celsius.
Tasman Saunas made the purchase process a breeze. His professionalism and commitment to customer satisfaction were outstanding. The installation team was equally impressive, with their efficient and detail-oriented approach ensuring a seamless setup.
The guys at Tasman Saunas are incredible! It took me a while to make my mind about choosing what was the best option for me but the guys were very knowledgeable and patient. I am very happy with the service and product.
Fantastic build quality and Dylan was a pleasure to talk to. Really happy with the experience!
