What's this under my bath?

[amfisted]

Just about to remove the bath in our bathroom, ready to replace it with a shower cubicle and thermostatic shower. Underneath the shower end of the bath ( the bath taps are at the other end, on the inside of an outside wall) I discovered the arrangement in the picture. Its a low wall, two courses of cinder/breeze blocks of the type that forms the inner skin of this bungalow's cavity wall. I've no idea why its there, unless to support something which is long gone, and I'll have to remove it in order to install the cubicle. Does anyone have any idea what its original function might have been? The wall behind it is the lower part of the tiled wall above the bath.

Apologies for the images not appearing the right way round ( the bottom one is upside down), but I don't seem to be able to permanently rotate them.

Blocks look like they are supporting the bath

They do, but as far as I can tell there a gap between blocks and bath, which makes it look as if whatever was originally supported by the blocks is now long gone. Were they still fitting cast iron baths in the 1960s?

Yeah. My house was built in 1964 with iron bath

I guess that solves it, then. The blocks were put there in 1965 to support a cast iron or maybe steel bath. I can therefore take them out without the house falling down.
