Grey water pipes snake around above floor - why?

[c0pper]

I'm looking to convert the back bedroom of my 1995 Leprechaun into an open studio space. However, what appears to be the grey water pipes snake from the shower and the sink on the opposite side, run along the walls, then snake back under the bed (in the picture the pipes are under the long carpeted blocks) before going under the floor at the foot of the bed.

Right now my idea is to raise the floor in the room a few inches to accommodate so that I can have a mostly flat, useable area (I can cut down the blocks in the middle of the room a little, can't do it with the ones along the wall because of valves and electrical lines and stuff), but I'm also wondering why they are installed above the floor anyway, and why the heck they needed to snake them all over the place instead of using more direct lines to the dump valve. Would it be possible to just rerun the pipes to have them go under the floor in a more direct manner, do you see any issue with this?

Raising the floor poses issues of tripping over the step as I walk in as well as decreased headroom.

Thanks!

Those appear to be fresh water lines, the waste lines are a much bigger diameter and are black. They also would not be routed under the bed. You can probably re-route them but you do need to track them back to their source to see what you're dealing with.

The pipes I'm talking about are indeed black, and are indeed routed along both walls (my toilet/sink is separate from the shower, across the hall) and then under the bed, above the floor. The wires and fresh water lines you see along the back wall are not what I'm talking about.

Your pipes are likely run inside the room where there will be heat if you ever decide to use it in freeziing weather.

Also, they are much easier to get to for any repairs.

I have considered both of these things, and they are good points. I don't plan to have it in freezing weather except maybe when it is stored/winterized, although it's been a Colorado Front Range-based rig since it was new, so maybe the original owner ordered it this way. Maybe I could wrap them in some insulation?

Perhaps I could add access panels if I decide to reroute the pipes and then redo the floor? As it stands the only thing easily accessible anyway is the valves which have small access panels along the wall routing, otherwise you already have to tear up some wood to get to the majority of the piping, as the wood coverings are not easily removed. I plan to remove the carpet and install a floating plank "wood" floor.
