The site of the swimming pool is to be sold off to save money
Bridgwater will be without any public swimming facilities from the end of August following a decision to close the existing Splash pool.
Sedgemoor District Council had originally agreed to not close the pool until a new one was built, but said it had run out of money.
A spokesman said closing the pool would ensure the money saved would go towards a new facility at Chilton Trinity.
The decision to close the pool and sell the land met with strong opposition.
Earlier this month swimmers staged a protest outside in a last minute attempt to save their pool.
Sedgemoor District Council claimed the pool currently costs the tax payer £700,000 per year.
The spokesman added it was aiming for 2012 as a timescale for a new pool and the council had committed £1.5m towards the pool at the Chilton Trinity site.
