Steel is much less likely to flex so you don't get the problem of the
sealant parting company with the bath/wall when fyull. Downside is the
bath water gets colder quicker ( or so I'm told) We've got a steel bath
and can't say I've ever noticed this though.





I've heard that insulating the underside of a steel bath with loft
insulation helps with the heat loss problem.
