Cedar Hot Tub Assembly Instructions
Introduction:
Thank you for selecting a Zen Bathworks tub! Your hot
tub will provide many years of soaking enjoyment.
Assembly will be easier if you follow the correct
sequence of steps and use the proper tools. ​ P lease take
the time to read the instructions completely and
carefully before starting the assembly process.
How wooden tubs hold water: ​ T he tub is
assembled dry. Because dry wood will swell a
significant amount when saturated with water, all
the joints compress tightly allowing the tub to hold
water.
Special note:​ ​ I t is important to keep the tub floor and
side staves stored in a dry place until assembly time​ . If
the tub gets wet prior to assembly, the wood may swell to
a larger size making assembly much more difficult and
slowing the sealing of the tub.

straps, benches.

Section 3: Site Preparation
Before assembling your tub, prepare a suitable spot for it.
Hot tubs will weigh from 1500 to 8000 lbs. when full of
water - so a stable foundation is essential. Cedar tubs
should be installed outdoors. You must provide for good
drainage and a solid foundation.
Outdoor installation:​
water from splashing, overflow, cleaning and draining
operations can be carried away from the site.
There are four basic styles of foundation for your tub.
