Alternative Installation Procedure
STONE BATHTUB INSTALLATION
General Considerations:
•
Floor support under bath must provide for a minimum of 1400 lbs. (635 kg).
Hot water supply should be 70% of capacity or greater.
•
We strongly recommend to have access from the floor below, it will help you to connect the
piping much more easily. Connecting without having access is also possible.
•
Determine the location of the bathtub, taking the position for the faucets into account as well as the water
supply piping and the drain.
•
Shims may be required to level the tub depending on finish floor surfaces. Shims are not included.
When adjusting the level allow a slight clearance (1⁄8”) between the finished floor and the apron. Note: use
a level to ensure accuracy.
•
Install the plumbing and drainage before securing the unit in place.
•
Before cutting a hole in the floor for drain piping, ensure the space is free of pipes, floor joists, heating ducts
and electrical wires. If the location for the bathtub is not free of these please contact a building structure
expert prior to cutting any joist.
•
It is recommended to have the plumbing installed by a professional plumber.
Floor opening
Determine the position of the bathtub allowing enough space for the plumbing and making sure that the drain and plumbing
are not directly above the floor joists. You will need to cut an opening in the floor. We recommend that you do this only
once you have the tub on hand.

Installation Instructions if you don’t have
access from the room below:
•
Before placing the bathtub, insert the male part of
the expansion joint (1) halfway to the female part (2).
Note
– these 2 parts are not supplied with the tub
and must be supplied by your plumber.
•
Place the bathtub by raising it up 3 1/2” with 4X4
pieces of lumber so you can still have access from the
bottom of the bathtub.
•
Align the drain (3) to the expansion joint (1) (fig.3).
•
From the bottom of the bathtub, tighten the collars
of the expansion joint (1) to the drain (3) (don’t forget
to use the seal washer in between).
•
Tighten the collars of the expansion joint (2) just tight
enough so the male part (1) can still slide in. (Fig.3)
•
Fill the water in the bathtub and let it drain out.
•
From the bottom, make sure that all the joints are
watertight.
•
Move the bathtub down slowly by removing the pieces
of lumber.
•
Do a silicone joint pressure seal between the base of the
bathtub and the floor. The sealer absolutely must
penetrate thoroughly beneath the rim of the apron.
This will ensure that no water seeps underneath the
bathtub, while also supporting the tub apron.
