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. Please take
the time to read the instructions completely and
carefully before starting the assembly process.
How wooden tubs hold water: The 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: It 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 1: Packing List
Locate the enclosed packing list to identify and confirm
that all items are included. A copy of the packing list is
inside the packaging. See Figure 1.1 to help identify the
major parts.
Section 2: Tools and Supplies Needed
A few basic tools and items are needed to complete the
assembly of your new tub. Gather what you will need
before you start.

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.
There are four basic styles of foundation for your tub.
You may consider a concrete pad, a gravel pad, piers
made of concrete or treated wood, or a deck.
See Figures 3.1 through 3.4 for ideas.
