Hot Tub Plumbing Pipe Size Guide

The following images are of actual pipe and should appear as actual size on your computer screen. The dimensions are as accurate as possible to enable you to perfectly match up your hot tub pipe.

The size dimension of the pipe relates to the internal dimension (ID) of the pipe.

*Please note Rigid hot tub pipe has not been included because it is very similar to the flexible pipe.

We mainly sell imperial PVC pipe in 'Flexible' and 'Rigid', but 'Rigid' metric is also available.
