I looked up a number of Spa/hot tub suppliers and saw lots of great reviews for Posh Spas; so decided to buy a hot tub from them. So glad I did, the service from visiting the showroom to installation has been superb. Lovely professional guys and provided a superb service and confirms that we we were right to use Posh Spas.

Everyone is so friendly and have so much knowledge as to what to do and when which confirmed that we made the right decision buying from Posh Spas. Highly recommend! The Hogbens xx
