Hi, I'm Andi!
Hi, Andi here. I own parts4tubs.com and also write all of the articles and info pages on the site. When you buy parts from my site you are buying from me - not just the internet! Some years back now, I built my own hot tub but struggled to find the information I needed. So, once my tub was complete, I started buildahottub.com to help others in their own pursuit of hot tub and plunge pools DIY building information. As that site grew in popularity, I was receiving more and more requests from hot tub owners like you about parts and assistance for their own plastic shell tubs. I found myself sending people over to other online stores to buy the parts they needed.So, I decided to create parts4tubs.com so that I could help everyone myself and supply the parts you need directly - Hopefully I can help you with the parts you need for your tub. Can't find what you are looking for? Then please get in touch. Cheers, Andi parts4tubs_shipping Just a note here on the shipping times - I am at the mercy of the carriers. These are the standard times I am being quoted but delivery may take longer than this - they are not guaranteed. Thanks!
