Hi everyone,
I am building a shower bench with white cedar and some of the joints are bridle joints. I know there is the option of using Titebond for water proof applications or polyurethane Gorilla glue, which can be a bit messy if you are not careful

Has anyone done a similar project requiring a water proof adhesive, who can provide some advice?

Most of the parts for the bench are 1-1/2” thick, and according to the drawing require to be joint with a bridle joint. I know mortise and tenon would seem more ideal but the client wants to see the corners with a bridle joint.

On top of that the bench has handles that have a curve to it. My stock is 2” thick so for the curves I am planning to join the wood and make it thick enough to create the curves

I will appreciate any insight or advice as to how to go about this project
