    The copper fin doesn't come in contact with the tub. It's not like a cast iron radiator were the water is running through it. There is no air circulation under the tub to produce heat. That set up wouldn't have even heated the room.

    Humm, a light bulb's filament doesn't touch the glass, but the glass gets plenty hot. Heat is heat...while there isn't much air in that cavity, what's there will circulate. Yes, my example isn't as extreme as the hot water in there, but even a convector that is closed up will get hot - it just won't warm the room as effectively.

    It would be good to hear from the OP to see how warm in real practice the tub got. Course, if they're running something like 120-degree water through it, it's not an issue.

    In the winter I did notice a slight warmth to the top of the skirt at times.I never thought I would find a radiator in it:(

    You can't touch a light bulb that's been on but you can handle copper fin that has 160-degree water running through it.

    Ok, I'm going to take out the panel in the closet on the left hand side of the picture. The 2x3 is going to be cut and then we will drag/walk the tub out through the closet. From there we will use either a dolly or slide it on the skirt.

    Ledger: this tub has no ledger and no shims and the feet rest on plywood, been here for 36 years! If I wanted a ledger would the cast tub need to be set in place and then marks put on the wall? Or would I measure based on the specs and put on a level board and set the tub in once?

    Thanks much:D

    What do the installation instructions say about it? The thing sits on the feet, is pretty heavy, but a ledger can ensure it can't tip a little.

    Kohler's installation instructions say for the tub to sit on only its 4 machined feet.

    *However*, these feet are very skinny (<1/4" wide) and will sink into the floor unless placed on metal shims. Also, they are not necessarily in-plane with each other. The Kohler Villager I just installed had warped and its feet were 1/8" out-of-plane. Wobbly tub, leaky drain (eventually).

    I eventually used a ledger board (despite Kohler's instructions saying not to) and am glad I did. No wobble. No sinking into the floor. Rock solid.

    I found it was an iterative process because the tub wasn't exactly true. Used deck screws to temporarily hold the ledger in place while I checked the tub for levelness and wobbles.

    Such is the nature of cast iron manufacturing I suppose. These beasts slump slightly as they cool, making them slightly different than spec.

    Do the drains have to be installed prior to dropping the tub in place? I have an opening to the drain pipe from underneath but it is small and covered with a bunch of other pipes.

    Thank you

    Thinking that your tub is going to be level is like expecting the floor to be level or all the walls to be square.

    A perfect tub install is often the "Apperance of perfection" not perfection its self.

    The last Kohler tub I installed was out over a 1/16". No way to get it perfect on all three sides so I just set it in the middle. The criss cross apple sauce marks where money. Like taking the average and setting it there.

    We set Villager and similar c.i. tubs on steel shims. The tricky bit, is getting the steel shims at the correct height. To do this, we check the feet of the tub to see where they line up and to verify if they're in-plane. Then, we use various thickness of plywood - without voids - to bring the steel to the correct height. We've tried the ledger bit, but the bottoms of the edges are often pretty rough, and removing/resetting c.i. tubs to get the ledger right is hard work and a pita. Not to mention, every time you set & reset one of these bad boys, you increase the risk of damaging something. :)

    The steel shims work. Once set and wall finishes installed, these things don't move. Ever. :)
