My over indulgent SAB-UPATE W PICS

So I have some plastic sheeting and oak paneled plywood laying around from another project and don't have the money right now unfortunately to buy a flow hood filter, so I decided to build an oversized SAB out of said materials. I was bored and made a crappy model in sketchup. What do you think? I ordered 28" cotton lined chem resistant rubber gloves off of amazon for 16 bucks and have some pool paint I am putting on the inside so I can put pure bleach in the box and not hurt it. Going with a high gloss pecan stain/poly combo on the outside. ? 
UPDATE:Got all the wood cut and first stain down, gonna poly it tomorrow and cut holes ect. I decided to make the lid the top section and am thinking about making it wooden. Cut some 2x2s I had to make a lip around the edge so the seal would be better. Also the extra weight of the wood vs the plastic will help to ensure a good seal and I can put 6-8 magnetic latches on it to further compress the weather seal to keep air out and not worry about breaking the lid every time I open it. I think its going to work pretty well, getting excited about not having to work in a tub anymore. Also, using this design, later down the road I can just get a big hepa and do a vertical stack flow hood (of course removing the bottom, making a side door, and putting it on a stand with a grate for stuff to sit on) and have the huge area of sterile air
EDIT: Here are some pics of the MOSTLY finished product.

Skip the gloves. Regular latex or nitrile gloves with (or without) some Tyvek sleeves will do you better.
Maybe cut the PVC pipes for the armholes shorter. From the way it looks in your pic, they're gonna be rather restrictive.
Double check all your edges. Silicone is your friend.
No reason for that little shelf thing in the back either. A sealed box with some holes is all you need.
Consider using your Plexiglas (I'm assuming that's what you're using) on the top and front of your box for better visibility.
You're gonna need a high gloss paint on the inside, too, so you can clean it easier and reduce the texture on the walls. Using pure bleach is just a waste of bleach. It works best at a 10% concentration.
It'd also ensure a better seal if you put the hinges on the bottom. That way you can put your materials on the platform then basically put the box around that. Kinda how you use the lid for the bottom of a plastic SAB.

I remember a member (I think it was Kalypto) who made a box like this and regretted it, it didn't work very well for him no matter what he tried.
My super-duper still-air box is just a box with two holes, but it sits inside the middle of a 3'x3'x6' grow tent that I work partially inside of.

Here's a thread about it.
The best SAB is going to be the one that sits in the room with the least amount of drafts IMO. My contam rate has remained at an all time low.

Yeah, the room its in has no ac vents and the only moving air is from fans that I place or the window unit which I turn off for at least 3-4 hours and run my little HEPA b4 doing any work. I want a SEALED box, and also a bigger one as doing big bags is almost impossible in the biggest tub I could find. -The "tubes" are not tubes but just a place holder to show where the gloves go, they are going to be fixed to the glass goles so NO air goes in or out once its sealed. -I am back and forth on the shelf, I just threw it in there. Probably going to just throw in a metal wire rack when I need it to keep jars separated. -The pool paint it SUPER high gloss plastic shell paint that is really thick and forms an almost acrylic like layer and is like 90 bucks for a gallon. Only reason I am using it is it is left over from painting the pool. -I was saying I CAN use pure bleach, not that I am gonna, 10% works best, pure bleach is too goopy and hard to get off. -And its lexan, which is stronger than plexi, and yes its on the front and top for exactly the reasons you stated. And as far as having issues I think as long as I keep my tolerances within 1/16" I can use the silicone glue on any seams to keep it sealed and the weather stripping on the lid edge SHOULD make things sealed enough to where it will be a big chamber of still air that I can work in. I am a big guy, and working in a rubbermaid tub drives me FUCKING CRAZY as I can only have like 10 jars or one bag and one jar and doing bags in there SUCKS COMPETE DONKEY DICK. And its not a small tub, its like 145 qts. I am HOPING this will work well and am pretty sure I will be able to get it to work properly. I am going out now to cut the wood and am gonna take a pic, do a materials list and just throw a quick how to up there and a simple log even if hardly anyone will make a box like this as its not exactly easy, or cheap. Well, its simple enough, but these oak panels cost like 54 each and the lexan was like 400 for 30x36x.223 10 pack of the sheets so a cheapo tub would be the way to go. BUT, if you already have the materials laying around (well most of em) and nothing to do all week but hobby work, this (I think) will turn out to be pretty cool. Rambled on a bit, just first time of the day, and I tend to ramble when I get hi.

I do work inside my grow tent as well . I thought I would be growing weed with it, but it turns out I don't have the patience for growing bud (even though it is about 100x less labor intensive) . I've thought about trying to turn it into a greenhouse setup, but I just get such a kick out of being inside the tent with the crumpled reflective walls that I couldn't bring myself to do it.
I wish I was up and running but having moved 4 times in the last 3 months is killing me.
Here's a stock image of my baby:

I had thought that, but the gd thing is gonna be so big I think a magnetic latch door like for a cabinet and a good job with sealing it and I think I will be good. Use at least 3 mabe 4 magnet latches and set them to hit home past where the weather stripping starts touching so it will really compress the seal. I am also going around and around about what to do about the actual seal, whether to make a flat surface that latches or just attach it straight to the edge of the plywood.

Updated the OP with pics. If anyone has ANY desire to replicate this and is unable to from my pics I would be glad to help. Thing left to do are: Attach gloves, drill hole for pressure exchange filter port, make and install filter, re-paint floor, re-do seal (maybe) as what I had holding the lid open for glues to dry fell and the lid fell down overnight making the seals move and not be in the right spot. Also I want to get some way to latch the lid down, was going to do magnets but want something a little more solid and I worry the amount of magnets needed to compress the seal properly will be too expensive and difficult to maintain. Maybe a faew diy electro magnets? Probably just gonna goelets and j-hooks or maybe a 2x2 bar going across the top with some threaded rod going thru with butterfly bolts on top. The last one is probably the easiest for daily use, the second cheapest. And lastly I need to paint something cool on it and clean it up a little. There are a few rough spots you can sorta make out in my crappy pics.
