unfortunatly its probably not worth the effort. but if you really like the bath then buy a fibre glass repair kit including the gelcoat and follow the instruction to repair it. I do warn you that you will probably have to take it out to do it as a newbie you will not get a perfect result and the cracks will show. it may be cheaper to replace the bath with an identical bath and keep the sports for the bedroom. cheers
