From Art Deco finery to a pond in a park, the UK has some beautiful, quirky and practical places to have a dip within the confines of its cities. Do you have one you’d recommend?

The best tips will appear in print in next weekend's Travel section and the winner, chosen by Tom Hall of Lonely Planet, will receive a £200 hotel voucher from Hotels.com, allowing you stay in thousands of places worldwide. Submit your tips by clicking on the blue button and using the text tab. Try and include as much detail as possible – location, any website addresses etc – and feel free to add a photo if you own the copyright to it, but it will be the text we’re judging! Your tip should be around 100 words long. Terms and conditions.

Closes 18 June 2014 at 6am GMT
