Poorly installed whirlpool tub
Posted by ED on January 17, 1999 at 12:35:18:
I have a question about how to correct poor installation of a Kohler whirlpool type bathtub which was installed about eight years ago for the original owners of my house. Installed in a three wall enclosure against an outside wall of the house, the tub drops about 1/8 to 3/16 inches on the outside wall when it is filled with water. You can tell this by the caulking line.

I can find no model number on the tub. It is six feet long and has six jets (three on each side). The tub is sitting on what appears to be cedar boards on top of a concrete pad that is about 1 1/2 inches thick. The front rim of the tub is sitting on a 2 X 6 frame, The back edge of the tub rim has no support. The tub is on a lower floor of the house above a crawl space framed with 2 X 8s (fifteen inches apart) topped with 1/2 inch plywood. There is a concrete block pier supporting one of the 2 X 8s toward the front side of the tub. There are two loosely constructed concrete block piers (stacked with no morter) on either side of the first pier.

Does the tub require framing along the back edge and will that solve the problwem? If not what is likely needed?

Thanks
