Manual •
Check order details and tub specifications for drain type and
rough-in location.¹
Standard Waste & Overflow
Most MTI drop-in tub models will accommodate a standard waste
and overflow. Use product specification sheets or measure drain
distance on tub to determine size and location of rough-in.
Integrated Overflow with Toe-Tap
MTI Tubs with an integral overflow come with a toe tap drain kit
and straight PVC drain fitting. Plan P-trap location directly below
tub drain.
The tapered side of the drain gasket will make contact with
the bottom of the tub. Be sure to use the provided no-grip disc
between the gasket and the drain fitting to avoid twisting gasket
while tightening.
CAUTION: DO NOT overtighten and DO NOT exceed 7ft-lbs
maximum. Product damage will occur.
