Cedar Hot Tub Assembly, Installation &
Maintenance Instructions
Introduction:
Thank you for selecting a Zen Bathworks tub! Your hot
tub will provide many years of soaking enjoyment. Even
if you purchased your tub factory pre-assembled, or are
hiring someone else to assemble it for you, please read
and understand these instructions as they contain many
relevant sections. Having an understanding of how your
tub went together and works is important, and will
increase your ability to maintain your hot tub properly. If
you are assembling your tub from a kit, assembly will be
easier if you follow the correct sequence of steps and use
the proper tools.
Please take the time to read the
instructions completely and carefully.
How wooden tubs hold water:
The tub is
assembled dry. When saturated with water the dry
wood will swell significantly. As the wood expands,
all the joints compress tightly allowing the tub to
hold water, provided it was assembled properly.
Special note:
It is important to keep the tub floor and
staves (The staves are the vertical wood parts that make
up the sides of the tub) 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 encumbering the sealing of the tub.

retention bands, bench segments.

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:
Good drainage is vital so that
water from splashing, overflow, cleaning and draining
operations can be carried away from the site. If not,
debris will collect around the lower areas of your hot tub
causing wood deterioration over time. Remember, wood
lasts longest either fully submerged, or ventilated .
Prolonged dampness will cause wood rot over time and
should be avoided wherever possible.
