Door can be left open if this is your preference. I treated my sister and I to a gift of Zero gravity floats. We are both OAP's . We were happy with the choice of leaving the doors fully open or slightly ajar or closed. The rooms which include their own shower are kept very clean. The room temperature was nice and warm and the shower was super! Ear plugs and light head rest are supplied. We brought our own pool slippers. We enjoyed a lovely mug of berry tea in the 'Chill out' room after. They staff are very helpful and polite. We highly recommend the floats and look forward to returning to try the other services.
