FREE STANDING TUBS
GENERAL INFORMATION
•
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.
•
The tub must be level
BASIC INSTALLATION PROCEDURE
•
Determine final location of the tub. Tub will sit on top of finished flooring.
•
Ensure location is structurally sound, flat and level.
•
Align the tub in a manner that the drain lines up with the P-trap in the floor. DO NOT LET THE TUB REST ON
THE DRAIN PLUMBING.
•
Check the tub for level. It must be level end to end and side to side.
•
Caulk the gap between the skirt and the floor.
SUPPLEMENTAL INSTALLATION INFORMATION
FIXTURES
•
No Fixtures can be mounted on the tub deck. Floor and wall-mounted fixtures are required.
•
Wall-Mounted – The position of the tub and the reach of the spout are critical. Pay special attention to the spout
reach when choosing your fixtures. Be careful to ensure the spout will extend out far enough to clear the tub deck
and the falling water will not hit too high up the side wall of the tub and splash.
•
Floor-Mounted – Some freestanding fixtures must be anchored to the tub drain for stabilization.
•
Remote Mounting Blower – Due to the limited space between the inner and outer shell on all of The Metro
Collection Freestanding tubs, the blower must be remote mounted. In addition to the air pipe there is one
electrical connections between the tub and the blower. The electrical connection and the air pipe exit through the
bottom end of the bath. It is always desirable to remote mount the air blower as close to the tub as possible to
minimize loss of heat. Pipe insulation may be used on the air line to minimize heat loss.
•
It is not recommended that the blower be mounted over 8 feet away from the tub. The supplied wiring
between the tub and the blower is approximately 10 feet long.
•
Remote blower locations – There are several locations where the blower can be located. There must be a GFCI
electrical outlet within 2 feet of the blower. The blower is approximately 9.25 inches long and 8 inches in diameter
and 5” high. Substantial ventilation is required to keep the blower from overheating and to supply the large volume
of air being sent to the tub. Never wrap insulation around the blower as this will cause the equipment to fail. The
best location is directly below the tub in the floor joists. This location keeps the distance short and offers easy access
from below. If the room below has a finished ceiling, there are many fixtures such as HVAC return that can be used to
camouflage the access panel in the ceiling. Other possible locations include an adjacent closet, vanity or a same
level attic. Every home is different and there may be other desirable locations. Keep in mind that the blower must be
accessible for any future servicing.
•
Remote Blower Kit – If the blower is not mounted directly adjacent to the tub, a remote blower kit will be required.
The kit consists of: extension pipe, couplings and cable. Please indicate the necessary length of pipe and cable re
quired.
