Mallard M32 shower floor spongy

Hello all. First time poster. I wanted to share a problem and my solution. Our new M32 shower floor seemed to be pretty spongy and I was concerned it might affect the plumbing from the movement. I opened up the access panel and noticed there was no support on the tub underlying base plywood floor on the exterior wall side of the shower drain. Not sure if this was a oversight or design flaw. Any way I elected to add 5” 2x2 blocks to add support. One major problem was there was no room to add blocks near the elbo and drain line because of the location of the drain line relative to the support plywood under the tub. I used two blocks on either side of the drain with a metal flat plate to create a support bridge. This fixed the problem. I have attached a. Fore and after pic. Also added two videos to YouTube to better explain this.

Good videos. We had the same issue on our Pioneer and solved it pretty much the same way. Much more solid feeling now.
