I have a 61" alcove ready for my 60" Mendota Kohler cast iron tub. How do I get the tub in there? I'm sure there are techniques for this. The Mendota has 4 small stubby feet that all the weight should sit on. I saw a previous post about cast iron tubs and flooring but I was confused. The flooring now is 3/4" plywood. This house was born in 1929 and I'm pretty sure originally there was a cast iron tub in it. So do I need more than the 3/4" plywood? Also, I'm concerned about the tub "sinking" into the wood. Do I need to put metal plates or something under those stubby feet? How would I do that? Thanks for your help. The tub is sitting in our driveway waiting for it's new home.
STATS: Mendota tub has apron front. No mention of ledger board to install. It says no weight should be on the apron, only on the feet.

To easily move your heavy tub into the alcove do this:

Make two skids out of 1x6 vinyl planks. Lay the skids running longways into the alcove spaced apart the same distance as the tub feet. The skids need to long enough so that 3' sticks out from the outer edge of the alcove. Lift the tub and place it on the two skids. If the tub slides easily, then you can just slide it in place - if it's hard to move, then get four teflon furniture slides and place one under each foot of the tub. Slide the tub as far back as it needs to go. Lift one end of the tub and remove the skid, repeat for other side. There you are.

AS far as adding something to the floor under the feet it really depends on how large the surface area of the foot is. Most are designed to be large enough to spread the weight on a solid subfloor. I would recommend that prior to installing the tub that you make sure that there is some solid framing under the subfloor in the area where the feet will stay. If not, then add some 2x framing to keep the plywood from bowing over time.
