What Our Customers Say!

Well what can I say, its just brilliant and so simple and to not have the issues of broken cover lifters is a hassle im pleased to not have. The design is simple but hugely effective, the cover is also fully attached to the spa so no blowing off in the wind and when folded back it sits snug up to the hot tub. Well worth it

OMG, what can I say? I cannot thank Gavin enough for all his help and support. He spent the time to understand all of my issues methodically and ran me through the basics of maintaining a hot tub from the initial fill to the regular maintenance needed. I placed an order with the bits I needed straight away.

I was previously using chlorine but swopped on to bromine which was initially a bit daunting but with the advice from Spachem they helped with fantastic knowledge and experience and were not pushy in trying to sell additional items.

Absolutely fantastic service and customer care. I was looking for a part for my hot tub and didn’t know where to start. SpaChem where fantastic, great and fast communication to help and advise and then when ordered the part came in super fast time. They even messaged to check it had arrived. Brilliant company to deal with will definitely be back and wouldn’t hesitate to recommend. Thank you!


I had a few issues getting to grips with a good hot tub maintenance schedule so I rang SpaChem as I get all my chemicals from them. I contacted them on WhatsApp and I spoke with Gavin directly on the telephone, who I cannot thank enough. He spent time with me going over what I did in order to understand where he could help me.


Very helpful chap super fast delivery will defiantly use spachem again.
