Tom –
Dear TimberIN Team,
Many thanks to the whole team at TimberIN. We are really pleased with our wood burning hot tub. The delivery was on time and efficient, although I would stress to people taking delivery to ensure you have lots of friends to help move it and/or equipment on hand if it needs to go over a fence. We were 9 people in the end who manoeuvred the hot tub into position through a very tight gate hole and it was no easy job.
We had the tub up and running within hours and have been surprised how often we’re using it even after the initial honeymoon period.
The quality and craftsmanship are great and unlike other more conventional ‘plastic’ hot tubs we saw it really does look great. So far all members and ages of the family have enjoyed it, from our nephews splashing around over Christmas, to Grandma relaxing under the stars with a drink on hand in the ‘bar’.
We’re looking forward to many years of fun use to come!
Tom and Family
