I did the tile in another bath - house built around 1990. Sub floor is in great shape and level(?).

Sterling (Kohler) 'Ensemble' unit. It appears there are 8 'feet' that are a part of the 'grid' affixed to the bottom of the unit. Their instructions say to lay the felt pad (IF included) under the unit so that 'feet' rest on it... continue with install. Then use shims to level the tub. When you put the tub into the stud pocket and fix it to the studs, unless you are two inches tall and can climb beneath it, how do I put in shims and know where they are needed?

Or the next section section of instructions they say to use a mortar base to level it. Lay 1 to 2" mortar under the tub and squish it down to level it etc.

I'm gonna go out on a limb and assumed the 'feet' are in plane with the bottom edge such that - assuming a flat level surface - there would be no need to shim.

I just got off the phone with Kohler. And I posed the same question about the 'felt pad', and shimming after the fact. They were unable to answer my question Just get a felt pad from one of the box stores...

Anyone have experience with this type of product - molded support grid with 8 tubular feet on the bottom? Will the "felt pad" be sufficient?

It's a trial and error thing. Place it, feel for wobble. Pull it out and make adjustments. Or avoid the whole fiasco and use mortar, which is the technique the pros use for obvious reasons. It's flexible and can be done in the blind.

And the reason it's necessary is because fiberglass things tend to be less precisely built than, say, wooden furniture. The front panel is left slightly longer to be sure that it rests tightly against the floor.

  • Got it, thanks, they make it sound like all I need is the pad. However, I had another go 'round with their support 2 minutes ago. They claim that if the floor is perfect all I need is the 'felt pad' which was explained to be landscaping material. Sounds to me like mortar wins the debate. I'm also thinking silicon along the floor edge is called for. – Lane M Jan 22 at 16:16

I have determined mortar is the only way to go. I talked to 3 different pros around here and all set it in a mortar base.

Thanks
