The centre cost£31m to build, against an original£20m budget, and was open for less than two years before faults forced Hackney to close it last autumn.
It was built with support from the national lottery and was among the largest council leisure projects of recent years.
Guy Nicholson, cabinet member for regeneration, told a scrutiny hearing: 'It is the mayor's view that there will be a Clissold leisure centre on this site, whether or not it is this centre.'
Hackney has sued architect Hodder Associates and cost consultant David Langdon Everest over the cost overuns.
It will not decide whether to take action against any company over the defects until it receives a report from consultants in September on the nature and extent of the faults.
The council compiled a list of 40 defects, the most serious of which included leaks from the swimming pool on to electrical equipment in the basement.
