Planning your own build?

If a build like this has you thinking, my DIY hot tub plans give you the CAD drawings, plumbing layout, parts list and video course. If your space needs something custom, I can draw it up with architectural CAD and a 3D plumbing design.

Hi, Andi here. I own Buildahottub.com and also write all of the articles and info pages on the site. 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 this website to help others in their own pursuit of hot tub and plunge pools DIY building information.

Fast forward to 2025, I've helped over 1400+ DIY customers just like you all over the world build hot tubs and pools. Have a good look around the site, there are lots of resources here. Please do get in touch if I can help you. - Cheers, Andi
