We did our own stalls inside our new pole barn. Husband built them. We used rough sawn White Oak, you get larger dimensions of boards when they are not planed smooth. Closer to a real 2" x 10" board. Also with fresh cut wood, you have an ability to drive the GALVANIZED nails that dry Oak won’t give you. You need to use galvanized nails because the tannin in green Oak will rust off the heads of plain steel nails, so in a few years you will be nailing boards back in place and it will be LOTS harder with dried wood! Know that green boards will shrink as they dry, so even making things nice and flush, you will have some gaps between edges later in time. We find the Oak tastes pretty bad, not much chewing on those boards. We still put edging on the windows, posts beside the doors to prevent chewing. Box stalls are 12ft x 12ft, fits most horses.
A less expensive metal for edging is galvanized sheet metal. We got our pieces bent-to-fit with rolled edges to prevent them being sharp. You have to give the dimensions to the Shop so they can size the metal pieces correctly. The metal was light and easy to handle, you can drive a nail thru it pretty easily. We used a Furnace shop that makes their own duct work, was happy to have the extra work from us. Their wide machines could bend long pieces of metal, made the fit perfect on the posts and windows.
We did pine boards on the aisle side of stall walls. We made the sliding doors, which are solid, don’t take up space on the aisle when open. A full sheet of plywood, hung from the nylon rollers by one narrow end, then put 2x6 boards around the outside edge with nails and glue, to make the board stiff. We did a cross-piece in the center, with an X across the lower half. Looks pretty nice, still in good shape MANY years later. Plywood is exterior grade, 1" thick, pretty impervious to damp, can take a big kick if needed. If I get a kicker in, they get retrained so they don’t do that again, using kick chains. Not having my barn trashed by a horse with bad habits!
We have Fortiflex corner mangers, though I am replacing them with antique iron ones as I find them. I have hay mangers over the corner feeder. Sounds silly, but we have moved the hay mangers locations with different horses. Currently one horse likes to watch things out his front window, so hay and grain mangers are in a front corner by the window. Other box stall has mangers in the back corner, horse is still able to see out the window but not close to it. She likes that way. Other horses have liked privacy for eating, or want to be up front to watch things that happen outside the stall. So we move things to make them happier. Water buckets are hung under the front windows, hoping for horses to drink more when standing to look out the window. Does help some.
I have rubber matting on the box stall floors, easier to clean, doesn’t let them dig holes.
Something to consider is putting in a nice tie stall. We have mostly tie stalls, 4 in the big barn that get used daily. We find them to be quite economical to bed and fast to clean to the floor daily. They are a great training device, horses learn much just being in them, getting worked around daily! Benefits are mine tie well for long times, move side to side as requested for filling buckets and hay mangers, not spooky with people and hose coming in from behind since they get rewarded most times with food! Horses load in trailers easily, with almost no effort. Seems they think it “Looks like a stall, just skinnier, so walk right in” to find the grain waiting for them. We don’t do it often, but if the center aisle is busy, we might back a horse into his tie stall, use it with cross ties for grooming or trimming manes. It was excellent with the Pony Club kids, 2 to a horse, with 6 horses being worked on at one time during various training sessions in braiding, clipping, mane pulling or thinning, in our barn. Sorry I only seem to have tie stall photos, none of the box stalls.

Left horse is 17H, while right side horse is about 16H, both are pretty full bodied. Still plenty of room in their stalls.

Tie stall also makes a good place to put wheelbarrow, tools, extra bales, out of your way but handy, when you are not keeping a horse in it. With a gate across the end, it can be a good place for pet goats, sheep, the pony if needed.
Our tie stalls are 12ft long, 5 1/2ft wide, hold our 16-17h horses that wear 84" blankets, have long necks, with plenty of room to lay down. They all seem to lay down at night, seem quite comfortable doing that in their tie stalls. They move over for me to go beside them, not kicky when surprised, since they are used to folks coming up behind them often. They don’t try to roll in tie stalls, have not had any ever get cast over a lot of years. The horses are turned out daily, so tie stall time is limited to 8-12 hours daily, depending on the time of year. Winters they are in longer than in summer time. A Draft size or Draft cross with bigger body might need a 6ft or 6 1/2ft wide tie stall to be more comfortable.
We have cement on the floor every where except the stalls. Surface is easy to clean, stays level, dry. We keep hay and other things like a carriage in the other part of the barn, don’t want dampness of dirt under them. Daily drive thru with tractor and spreader has no effect on my floors. We did use a coarse broom to rough the aisle after pouring that part. Has provided pretty good traction to the horses walking thru for many years. I use the leaf blower so that floor is clean after sweeping with the broom. Broom moves the bigger stuff, dirt piles, hay chaff, so it doesn’t just swirl around behind me. Leaf blower takes too long for that, but good on finish of dusty stuff removal broom won’t get. I have both end doors open to make dust leave fast, I put on a paper dust mask or pull up a bandana over mouth and nose so I don’t have to be breathing dirt. Horses are ALWAYS outside when the leaf blower is used to prevent breathing issues with dust and dirt in the air.
Hope some of these ideas are useful, will save you money over purchasing ready made stuff.
