Shed Base

I have built a wood shed base out of 2x4's for a Suncast resin shed that is 7x7'. The cross beams are at about every 14". The instructions also call for laying plywood on top of the 2x4's before laying down the shed floor. My question is how important is it to laydown the plywood? Seems like overkill to me.

You may be punished for not following manufacturer's instructions, should the shed not perform to your expectations. As in the company not standing behind its warranty. Spend a few bucks on plywood, just to play it safe.

And you did use PT 2 x 4s, yes?

I have built the same shed for a client, and recommend the plywood. The instructions I had called the plywood an "option", but believe me, you will not regret doing it right. BTW, this is by far the best shed I have installed for clients. It merely "fell" together.

Those 2 X 4's are about 1/2 the size they should have been and are going to sag for sure.
I would use 3/4" T X G Advantec for the subflooring. Far stronger and moisture resistant then plywood.
