Installation Instructions – Tubs with Integral Overflow*
The integral overflow tubs by MTI Baths require only the waste to be installed. The P-trap will be located directly
below the drain (see tub specification sheet). The tub comes equipped with a toe tap drain and PVC drain fitting.
1. Adhere tub to the finished floor using clear silicone. Make sure that tub is precisely located where desired
and that the hole in the floor for the drain aligns with the drain.
2. Install drain on tub using clear silicone under waste flange and on both sides of the rubber gasket on
underside of the tub. MTI recommends using a small amount of clear silicone on the threads of the PVC
drain fitting to act as a thread sealant. Tighten until it seats, plus one quarter turn. Finish installation from
below by connecting PVC drain fitting to P-trap using PVC cement.
3. Allow time for silicone to cure and water test for leaks. Many products are ready to test in as little as 30
minutes. Please refer to product label for details.
1. Stub out drain and P-trap with 1 ⁄ schedule 40 PVC pipe at least 1” above finished floor. Because the height
will vary slightly from tub to tub, box out around the pipe to allow trimming this pipe below grade upon
installing the MTI supplied fitting. The fitting is approximately 3” in diameter.
2. Determine gap between underside of tub (at drain) and the floor. Shorten 1 ⁄ inch pipe to allow the supplied
fitting and gasket height above the finished floor to match this gap. Glue fitting to pipe with PVC cement,
again making sure the final height matches the gap (remember to allow for the thickness of the rubber
gasket). Make sure that the top of the flange is level.
3. Use clear silicone to hold rubber gasket on top of flange. Apply another bead of silicone on top of gasket.
Put a small amount of silicone in the top threads of PVC drain fitting to act as a thread sealant. Adhere tub
to the finished floor using clear silicone. Immediately wipe o any excess silicone that may be on the floor
or exterior of the tub. Make sure that the drain hole, gasket and flange align so that the waste flange can be
threaded in from inside the tub.
4. Place a small bead of silicone under waste flange and thread into PVC drain fitting. Tighten until it seats plus
one quarter turn.
5. Allow time for silicone and water test for leaks. Many products are ready to test in as little as 30 minutes.
Please refer to product label for details.
MTI RECOMMENDS USING CLEAR 100% SILICONE SEALANT. DO NOT USE PLUMBER’S PUTTY.
