FREESTANDING BATH GENERAL GUIDELINES
IMPORTANT: Do not attempt to remove the foam from the bottom of the tub. Doing so may cause damage
and will void the warranty.
Rough in Dimensions –
For critical dimensions, we suggest taking the measurements of the actual
tub on site. All printed specifications are +/- ½ inch and subject to change without notice.
Access panel –
A removable access panel is located on the drain side of the bath, unless specified without
a panel. It provides access for installation of the waste and overflow. It is held in place by covered stainless
steel screws.
Fixtures-
No fixtures can be mounted on the tub deck of MTI BASICS freestanding tubs*. Floor-
or wall-mounted fixtures are required.
(*Except MBOFSX6636, which has an extended deck for
mounting a faucet and/or handshower.)
Wall-Mounted –
The position of the tub and the reach of the spout are critical. Ensure the
spout will extend out far enough to clear the tub flange and the falling water will not hit too
high up on the side wall of the tub and splash.
Floor-Mounted –
Some freestanding fixtures must be anchored to the tub drain for
stabilization. The drain and overflow is concealed under the access cover so anchoring to the
overflow pipe (or tub structure) is not possible. Many kits (with minor modification) can be
mounted to the wall (rather than the drain pipe) for stabilization.
Virtual Spout -
If your tub was ordered with the Virtual Spout tub filler, the tub will fill through the
small port on the inner wall of the tub. Incoming water is connected to mixing valves mounted on the
wall, or a small platform built adjacent to the tub. Output from the mixing valves must then be tied into
the brass Wilkins double check valve, located behind the access panel by the drain. Please check
local codes for specific backflow requirements.
INSTALLATION INSTRUCTIONS FOR FREESTANDING TUBS
1.
Determine final location of tub. The tub will sit on top of the finished floor, however, the drain
will sit approximately 1/2” - 1 1/2”
below
the finished floor. Tubs installed on a slab foundation
may require extra effort to gain clearance for the drain.
2. Ensure location is structurally sound, flat and level. See individual specification sheets for tub
weights and water capacity.
3. Remove access panel on rear of tub.
Save the screws and screw cap covers
for reinstalling later.
4. Roll tub onto front face being careful not to damage the acrylic finish. Use packing blanket or
other suitable material to protect the finish of the tub.
5. Install waste and overflow. Use 100% clear silicone to seal. Do not use plumbers putty as it may
discolor the acrylic or drain finish over time. Plumbers putty can dry and crack, leaving open the
opportunity for leaking. Many silicone products will be set in 30 minutes - check product label.
