||I saw some women climbing up a narrow stairs with a heavy bathtub on
their back on TV. I felt sorry for them but at the same time I wondered
why they were carrying such a heavy bathtub.
I doubted if why FRP had to be used for a bathtub with iron frame and
why it had to be so rigid. I thought it's CFRP 's turn to be used and
started the design immediately. As soon as I started, I became
incredibly busy and this project was automatically put on hold.
But this is a project I want to dig up from the past and start
development as an ultimate eldercare bathtub in the near future.
